The present invention relates to a pipe connecting device, and more particularly, to a device for interconnecting a plurality of coupling objects including at least one pipe while ensuring continuity of the flow path.

Water purifiers, air nozzles, and the like, which are widely used in recent years, are provided with pipes for providing a liquid or gas flow path.

Such a pipe is connected to another pipe or filter through a predetermined pipe connection device, and FIG. 7 shows a conventional pipe connection device.

7 is an exploded perspective view of a conventional pipe connecting apparatus, and FIGS. 8A and 8B are cross-sectional views illustrating pipe coupling states of a conventional pipe connecting apparatus, respectively.

Conventional pipe connecting apparatus, as shown in these drawings, three pipe coupling holes 111 are formed so as to be exposed to the outside approximately T-shaped connection body 110 and each pipe coupling hole ( Three reverse catching members 120 mounted one by one on the 111, and has a rubber ring O-ring 161 installed one inside each of the pipe coupling hole 111 beyond the reverse catching member (120).

In addition to the pipe coupling hole 111, the connection body 110 is formed with an internal flow passage 113 to connect the pipe coupling holes 111 to each other.

Each pipe coupling hole 111 is formed to have a reverse catching slope section 111a gradually narrowing toward the outside.

Pipes 201 and 202a are coupled to each pipe coupling hole 111 one by one. The pipe 202a is formed integrally with one end of the filter 202 here.

Each reverse catching member 120 has a direction perpendicular to the plate surface from the circumferential region of the support plate 121 having the tube insertion hole 121a formed in the central region and the bottom tube insertion hole 121a of the support plate 121. It has four elastic wings 122 extended.

Each elastic wing 122 has a stopper jaw 122a formed on an outer surface thereof, and one pressing pin 122b is coupled to an inner surface of the stopper jaw 122a.

Reverse locking member 120 having such a configuration is a pipe coupling hole so that the pipe insertion hole 121a communicates with the pipe coupling hole 111, and the stopper jaw 122a enters the inside beyond the reverse locking slope section 111a. It is mounted at 111. Here, the operation of mounting the reverse catching member 120 to the pipe coupling hole 111 is made of a state in which the elastic wing 122 is pressed in a direction approaching each other.

Referring to the method using a conventional pipe connecting device having the above-described configuration is as follows.

First, a method of coupling the pipe 201 to the connection body 110 is as follows.

The O-ring 161 is mounted on one of the pipe coupling holes 111, and then the pipe 201 is sequentially passed through the through-hole 131, the pipe insertion hole 121a, and the O-ring 161 in a fitting manner. Let's do it.

Next, the pipe 201 is pulled in the opposite direction to the insertion (when negative pressure is generated inside the pipe coupling hole, this operation can be omitted). Here, the operation of pulling the pipe 201 in the opposite direction of insertion is performed until the stopper jaw 122a is caught by the reverse catching slope section 111a until the movement of the reverse catching member 120 is blocked. The support plate 121 is spaced apart from the connecting body 110 when the movement of the reverse catching member 120 is blocked.

Next, the pipe 202a can be coupled to the connecting body 10 in the same manner.

Meanwhile, when the pipes 201 and 202a are to be separated from the connecting body 110, the pipes 201 and 202a are made in the following manner.

First, in the case of the pipe 201, the reverse locking member 120 is pressed toward the O-ring 161 so that the locking state of the stopper jaw 122a and the reverse locking slope section 111a is released using a nail.

In the case of the pipe 202a, since the separation distance between the reverse locking member 120 and the filter body (except the pipe 202a) is small, it is difficult to use the nail, so that the stopper jaw 122a is reversed by using the lever of the tool. The reverse locking member 120 is urged toward the O-ring 161 so that the locking state of the inclined section 111a is released.

That is, the end of the tool is inserted into the space between the support plate 121 and the filter body, and then a force is applied to the reverse catching member 120 using the filter body as a support point.

Next, the pipe 201 or the filter 202 is pulled in a direction away from the connecting body 110 while the reverse catching member 120 is pressed.

Meanwhile, in the case of the conventional pipe connecting device shown in FIG. 7, the connecting body 110 is configured to have three pipe coupling holes 111, but as shown in FIG. There is also an example configured to have one filter coupling hole 112.

9 is an exploded perspective view of another conventional pipe connecting apparatus.

In the case of other conventional pipe connecting devices, the pipes 201 are coupled to one pair of pipe coupling holes 111, and the filter 202 is coupled and separated by a screw coupling method or the like to the filter coupling holes 112. Except for the conventional piping connection device shown in Figure 7 has the same structure and function.

However, according to the conventional pipe connection device, since the force to apply the force to the reverse locking member 120 using a nail or a tool is a problem that the operation of separating the pipes 201, 202a from the connection body 110 is complicated and difficult there was.

Accordingly, it is an object of the present invention to provide a pipe connecting device that allows the pipe to be easily separated from the connecting body.

According to the present invention, a plurality of coupling holes in which a plurality of coupling objects including one or more pipes are coupled to each other are formed to be exposed to the outside, and the coupling holes of the coupling holes are coupled to the outside of the coupling holes. A connecting body having an internal flow path formed to connect the coupling holes with each other, a support plate having a tube insertion hole formed in a central region, and one surface of the support plate, and a circumference of the tube insertion hole A plurality of elastic wings are formed extending from the area in a direction perpendicular to the plate surface and each of which has a stopper jaw formed on the outer surface thereof, the pipe insertion hole communicates with the pipe coupling hole, and the stopper jaw extends the reverse locking slope section. In the pipe connecting device having a reverse catching member mounted to the pipe coupling hole so as to enter the interior beyond The through hole is formed in the central area so as to penetrate along the longitudinal direction, and the through hole communicates with the tube insertion hole and presses the reverse catching member to release the locking state between the stopper jaw and the reverse catching slope. It is achieved by a pipe connecting device comprising a reverse locking release member coupled to the connecting body to be movable along the longitudinal direction of the pipe coupling hole.

Wherein the reverse catching member has a moving protrusion formed on an inner surface of the through hole so that the reverse catching member can be easily pressed and the pressurizing state can be stably maintained when the pipe is separated; The connecting body is configured to form a guide rail for guiding the moving projections so that the reverse locking member moves along the longitudinal direction of the pipe coupling hole when the reverse locking member is rotated on an outer surface thereof. The locking release member has a pressing plate formed with the through hole and a pressing operation portion extending along a direction perpendicular to the plate surface from the circumferential edge of the pressing plate and having an inclined surface formed on the inner surface thereof to descend toward the pressing plate. It is coupled to the connecting body to surround the pipe coupling hole; The connecting body may be configured such that an actuating protrusion interacting with the actuation inclined surface is formed such that the reverse catch release member moves along the longitudinal direction of the pipe coupling hole when the actuation pressing portion is pressed on an outer surface.

And the moving projections are formed in a pair with a phase difference of 180 degrees so that the rotation operation direction can be arbitrarily selected when constituting the locking release member including the moving projections; Preferably, the guide rails are formed to have a pair of V-Zegs connected to each of the moving protrusions one by one and connected to each other.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of a pipe connecting device according to an embodiment of the present invention, Figure 2a and 2b is a cross-sectional view showing a pipe coupling state of the pipe connecting device according to an embodiment of the present invention, respectively.

Piping connection device according to an embodiment of the present invention, as shown in these drawings, three pipe coupling holes (11) and the connection body 10 of the approximately T-shape formed to be distributed to the outside and , Three reverse catching members 20 mounted one by one in each pipe coupling hole 11, and an O-ring 61 made of rubber material installed one inside each of the pipe coupling holes 11 beyond the reverse catching member 20. Have

In addition to the pipe coupling hole 11, the connection body 10 has an inner flow passage 13 formed to connect the pipe coupling holes 11 to each other, and a guide rail 14 is formed on the outer surface.

Each pipe coupling hole 11 is formed to have a reverse catching slope section 11a gradually narrowing toward the outside.

Pipes 201 and 202a are coupled to each pipe coupling hole 11 one by one. The pipe 202a is formed integrally with one end of the filter 202. Here, the pipes 201 and 202a constitute a coupling object.

The guide rail 14 is formed in a rectangular cross section, and is divided into a pair of V-shaped sections 14a connected to each other.

Each V section 14a guides each moving projection 32 to be described later one by one when rotating the reverse stop release member 30.

Each of the reverse catching members 20 is perpendicular to the plate surface from the circumferential region of the support plate 21 in which the tube insertion hole 21a is formed in the center region and the bottom tube insertion hole 21a of the support plate 21. It has four elastic wings 22 extended.

Each elastic wing 22 has a stopper jaw 22a formed on an outer surface thereof, and a crimping pin 22b is coupled to an inner surface of the stopper jaw 22a.

Reverse locking member 20 having such a configuration is a pipe coupling hole so that the pipe insertion hole 21a communicates with the pipe coupling hole 11, and the stopper jaw 22a enters the inside beyond the reverse locking slope section 11a. 11 is mounted. Here, the operation of mounting the reverse catching member 20 to the pipe coupling hole 11 is made of a state in which the elastic blade 22 is pressed in a direction approaching each other.

The reverse locking release member 30 is formed in the central region so that the through hole 31 penetrates along the longitudinal direction, and a pair of moving protrusions 32 are formed on the inner surface of the through hole 31. .

The pair of moving protrusions 32 are formed with a phase difference of 180 degrees. And the pair of moving protrusions 32 are formed to have a gap with respect to the inner surface of the guide rail (14). Accordingly, when the reverse catching member 20 moves in a direction away from the O-ring 61, the reverse catching release member 30 may also move together.

And the reverse stop release member 30 is formed at one end of the pressing flange 33 is bent toward the inside, a pair of holding protrusions 34 on the outer surface is formed with a phase difference of 180 degrees along the longitudinal direction.

In the reverse locking release member 30 having such a configuration, the through hole 31 communicates with the tube insertion hole 21a, and each moving protrusion 32 has one center of the V section 14a of the guide rail 14. It is coupled to the connecting body 10 to be inserted in.

Accordingly, the reverse stop release member 30 is moved along the longitudinal direction of the pipe coupling hole 11 by the rotation operation. Pressure is applied to the reverse catching member 20 while the reverse catching release member 30 moves along the longitudinal direction of the pipe coupling hole 11, and thus, the stopper jaw 22a and the reverse catching slope section 11a are removed. The jam state is released.

Referring to Figures 3a and 3b using a pipe connecting apparatus according to an embodiment of the present invention having such a configuration as follows.

First, the method of coupling the pipe 201 to the connection body 10 is as follows.

After the O-ring 61 is installed in one of the pipe coupling holes 11, the pipe 201 is sequentially passed through the through-hole 31, the pipe insertion hole 21a and the O-ring 61 in an interference fit manner. . Here, each moving projection 32 of the reverse stop release member 30 maintains the state inserted in the center of the V section (14a) of the guide rail (14).

Next, the connection body 10 is grasped and the pipe 201 is pulled in the opposite direction of the insertion (when negative pressure is generated inside the pipe coupling hole, this operation can be omitted). The operation of pulling the pipe 201 in the opposite direction to the insertion is performed until the stopper jaw 22a is caught by the reverse catching slope section 11a and the movement of the reverse catching member 20 is blocked. The support plate 21 approaches the pressing flange 33 when the movement of the reverse catching member 20 is prevented.

Meanwhile, the operation of separating the pipe 201 from the connecting body 10 will be described.

Holding the gripping protrusions 34, the reverse locking member 30 is rotated.

When the reverse locking release member 30 rotates, the reverse locking release member 30 and the reverse locking member 20 move along the longitudinal direction of the pipe coupling hole 11, and the stopper jaw 22a and the reverse locking slope section ( The locking state of 11a) is released.

Next, the pipe 201 is pulled in the opposite direction to the insertion in the state where the moved reverse catch release member 30 is gripped to separate from the pipe coupling hole 11.

Next, the holding state of the reverse stop releasing member 30 is released. Accordingly, when the reverse catching member 20 moves in a direction away from the O-ring 61, the reverse catching release member 30 may also move together.

The pipe 202a can also be coupled to or separated from the connecting body 10 in the same manner.

Meanwhile, in the above-described embodiment, the reverse locking release member 30 is configured to move along the longitudinal direction of the pipe coupling hole 11 through the rotation operation, but the reverse locking release member 30 is connected to the pipe coupling hole through the pressure operation. It can be comprised so that it may move along the longitudinal direction of (11).

Figure 4 is an exploded perspective view of a pipe connecting device according to another embodiment of the present invention, Figure 5 is a cross-sectional view showing a pipe coupling state of the pipe connecting device according to another embodiment of the present invention.

Piping connection device according to another embodiment of the present invention has the same structure and function as the pipe connection device according to an embodiment of the present invention except for the connection body 40 and the reverse locking release member 50 and These same components are shown in FIGS. 4 and 5 with the addition of a dash '.

The connecting body 40 according to another embodiment of the present invention is configured in the form of a roughly T-shape formed so that the three pipe coupling holes 41 are exposed to the outside, and the reverse locking member 50 is each It is coupled to the connecting body 40 to be movable along the longitudinal direction of the pipe coupling hole 41.

The connection body 40 has an internal flow path (not shown) formed in the pipe coupling hole 41 so as to connect the pipe coupling holes 41 to each other, and the working protrusion 44 is formed on the outer surface.

Each pipe coupling hole 41 is formed to have a reverse catching slope section 41a that becomes narrower toward the outside.

The working protrusion 44 is formed to interact with the working inclined surface 52a to be described later when pressing the pressing manipulation unit 52 to be described later.

Each reverse locking release member 50 has a pressing plate 51 having a through hole 51a formed therein, and a pressing operation portion 52 extending along a direction perpendicular to the plate surface from the circumferential edge of the pressing plate 51.

The pressing operation part 52 is formed in the inner surface with the working inclination surface 52a which descends toward the pressing plate 51, and the pair of cut-away incisions 52b are formed with the phase difference of 180 degree | times.

Reverse locking member 50 having such a configuration is coupled to the connecting body 40 so that the pressure control unit 52 surrounds the pipe coupling hole 41.

In the state in which the reverse locking release member 50 is coupled to the connection body 40, the action inclined surface 52a is in contact with the action protrusion 44. Accordingly, the reverse stiffening release member 50 is moved along the longitudinal direction of the pipe coupling hole 41 by the pressing operation. Pressure is applied to the reverse catching member 20 'while the reverse stiffening release member 50 moves along the longitudinal direction of the pipe coupling hole 41, and thus the stopper jaw 22'a and the reverse catching slope section ( The locking state of 41a) is released. Then, the pair of escape cuts 52b facilitates the pressing operation of the reverse stiffening release member 50.

In the pipe connecting apparatus according to another embodiment of the present invention having such a configuration, as shown in FIGS. 6A and 6B, when the pipe 201 is separated from the connecting body 40, the pressure connecting unit 52 is pressurized. By the interaction between the working slope 52a and the working protrusion 44, the reverse catching release member 50 and the reverse catching member 20 'are moved along the longitudinal direction of the pipe coupling hole 41 and the stopper jaw. It can be used in the same manner as in the case of the embodiment of the present invention except that the locking state between the 22'a and the reverse catching slope section 41a is released.

According to the embodiments of the present invention as described above, by releasing the locking state of the stopper jaw (22a, 22'a) and the reverse stop slope (11a, 41a) through the reverse stop release member (30, 50), The pipes 201 and 202a can be easily separated from the connecting bodies 10 and 40.

Stopper jaw (22a, 22'a) through the interaction of the guide rail 14 and the moving projection 32 of the reverse locking member (30, 50) or the action of the inclined surface (52a) and the action protrusion 44 By releasing the locking state of the over-locking inclination section (11a, 41a), it is possible to easily press the reverse catching members (20, 20 ') during the separation of the pipe and to maintain a stable pressurized state.

In addition, the pair of moving projections 32 form a phase difference of 180 degrees and the guide rails 14 are formed to have a pair of V-sections 14a for guiding each moving projection 32 one by one, thereby preventing the reverse jamming member. By rotating the 30 in an arbitrary direction, the pipe 201 can be separated from the connecting body 10.

Meanwhile, in the above-described embodiment, a case in which three pairs of pipes 201 and 202a are coupled to the connection bodies 10 and 40 is described. However, one or two pipes and one screw-type filter are connected to the connection body 10. It is a matter of course that the present invention can be practiced for a combination of various types of coupling objects including a single pipe, such as coupling to (40).

Therefore, according to the present invention, by releasing the locking state between the stopper jaw and the reverse locking inclination section through the rotation operation or the pressing operation of the reverse locking release member, the pipe can be easily separated from the connecting body.
