Description

Vacuum adsorption device {Vacuum adhesion device}

The present invention relates to a vacuum adsorption device, and more particularly, to a vacuum adsorption device that can be used to hang a tile, a wall, or the like by using a vacuum adsorption force, which can firmly adsorb to a wall surface having a non-flat surface.

Conventionally, household goods such as towel racks, soap trays and tissue hangers have been used to fix the walls using nails or adhesives. However, this method has a problem that the walls are damaged. It is fixed to and used.

In general, the vacuum suction port is attached to a flat surface of a glass, a mirror, a tile or the like, and is used by many users because it is easy to attach or detach the fixing position so that the user can easily change the mounting position.

As shown in FIG. 1, the conventional vacuum suction port is integrally coupled with the soft suction plate 10, the cover part 8 covering the soft suction plate 10, and the soft suction plate 10. It consists of a screw rod (6) formed to penetrate to the rear side of the cover portion (8), and the nut operating portion (2) coupled to the screw rod (6).

In the conventional vacuum suction port, the soft suction plate 10 is pulled by rotating the nut operating part 2 while pulling the screw rod 6 in a state in which the soft suction plate 10 is brought into close contact with a surface such as the tile surface 12. The central portion is pulled into the cover portion 8 while being sucked while a vacuum is generated between the surface of the tile surface 12 and the like.

In the conventional vacuum suction port as described above, since the adsorption plate 10 is composed of one, the edge of the adsorption plate 10 should be closely adhered to the surface such as the tile surface, so that the adhesion force is remarkably inferior or unevenly adhered to the uneven surface. There is a problem that does not come up.

In addition, when used in a bathroom or kitchen where a large number of tiles are attached, since the grooves are formed between the tiles and the tiles, when the suction plate 10 spans the boundary line between the tiles, the vacuum is maintained due to the grooves. There is a problem in that it is not adsorbed properly, so that it is not only very difficult to select the attachment position of the adsorption plate 10, but also many restrictions are imposed on the size of the adsorption plate 10, resulting in inconvenience in use.

Accordingly, the present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a vacuum adsorption device capable of firmly adsorbing even on a non-flat surface such as a tile on which embossing or the like is formed.

The vacuum adsorption device of the present invention as described above, the seal layer is formed on one surface, the adsorption face plate having a plurality of perforated adsorption holes in the thickness direction; A pulling piece having a pull protrusion formed to be fitted into and coupled to the suction hole on one surface thereof, and a pulling piece having a lifting rod formed to protrude from the other surface; An elastic portion formed to fill a gap between the pulling protrusions being coupled to the suction hole; A cover having a stepped portion formed by engaging an outer circumferential portion of the adsorption face plate, wherein the lifting rod is formed to pass through the through hole; The screw is coupled to the lifting bar, characterized in that it comprises a rotating member for lifting the lifting bar by a rotary motion.

A hole penetrating in the longitudinal direction may be formed in the pulling protrusion.

The end of the pull protrusion is preferably formed to be located in the thickness direction of the adsorption hole of the adsorption face plate.

The suction hole has a narrow upper side and a wide trapezoidal shape at the lower side, and the seal layer is silicon or polyurethane.

In addition, the vacuum adsorption apparatus of the present invention comprises: a suction surface plate having a plurality of adsorption holes perforated in the thickness direction and having a rubber coating layer on an outer surface thereof; A pulling piece having a protrusion formed to be pressed into the suction hole on one surface thereof, and a pulling piece having a lifting rod formed to protrude on the other surface thereof; A cover having a stepped portion formed by engaging an outer circumferential portion of the adsorption face plate frame, the lifting rod being formed to pass through the through hole; The screw is coupled to the lifting bar, characterized in that it comprises a rotating member for lifting the lifting bar by a rotary motion.

The end of the pull protrusion is preferably formed to be located in the thickness direction of the suction hole of the adsorption face plate frame.

Here, the pull piece is formed by drilling holes in the thickness direction, and the adsorption face plate frame is perforated with the adsorption holes corresponding to the fitting holes, and penetrates through the corresponding adsorption holes to be fitted into the fitting holes. It may further include an adsorption rod having a locking projection at one end.

In addition, it is preferable that the adsorption hole into which the adsorption rod and the adsorption rod penetrate is formed so that the diameter of the lower end is wider than the middle portion.

According to the present invention, there is an effect that the grooves are formed on the interface between the tiles, or even on a non-flat surface such as a tile on which embossing or the like is formed, using a plurality of adsorption holes, it is possible to firmly adsorb them.

Further, according to the present invention, there is an advantage that the vacuum adsorption device can be freely designed and used in various forms.

With reference to the accompanying drawings, the vacuum adsorption apparatus of the present invention as described above will be described in detail below.

Figure 3 is a partial cutaway perspective view of the combined state of the vacuum adsorption device of the present invention, Figure 4 is a cross-sectional view and a partially enlarged view of the vacuum adsorption device of the present invention, Figure 5 is a tile attached state of the vacuum adsorption device of the present invention It is a figure which shows.

In the vacuum adsorption apparatus of the present invention, as shown in FIG. 3, a plurality of adsorption holes 43 are punctured in the thickness direction of the hard adsorption face plate 40.

In addition, in the adsorption face plate 40, a soft seal layer 42 is formed on one surface in a thickness direction except for the adsorption hole 43.

The soft seal layer 42 formed as described above is preferably a silicone or polyurethane in order to improve adhesion to the surface to be closely adhered to the tile surface or the like.

A pulling protrusion 33 formed on one surface of the pulling piece 30 is fitted into the suction hole 43 of the suction surface plate 40. Here, the lifting bar 32 is formed to protrude from the central portion of the other surface of the pull piece 30.

The pulling protrusion 33 formed in the pulling piece 30 may have a hole 35 penetrating in the longitudinal direction in the central axis.

When a filler such as rubber is injected into and filled in the hole 35 formed through the central axis of the pulling protrusion 33 in the longitudinal direction, the bonding force with other parts can be further increased.

As shown in FIG. 3, the pulling protrusion 33 formed to protrude on one surface of the pulling piece 30 is inserted into the suction hole 43 of the adsorption face plate 40 in the thickness direction, and then the pulling protrusion 33 is disposed. Is inserted into the adsorption hole 43, the elastic portion 50 is filled between the elastic material such as MBR rubber is formed therebetween.

That is, an elastic material such as MBR rubber is injected into the gap 35 between the pulling protrusion 33 and the suction hole 43 and into the hole 35 formed through the pulling protrusion 33 to form the elastic portion 50. When the pulling projection 33 is buried in the elastic portion 50 is firmly coupled.

At this time, the end of the pulling projection 33 of the pulling piece 30 is in the thickness direction of the suction hole 43 of the suction surface plate 40 so as not to protrude from the seal layer 42 formed on the suction surface plate 40. It is preferably formed so as to be located inside. This means that when the pulling protrusion 33 is formed to protrude more than the seal layer 42, a vacuum may not be formed at the end of the suction hole 43, and thus the pulling protrusion 33 is positioned inside the thickness direction of the suction hole 43. It is desirable to have a length of the degree.

An elastic portion 50 may be formed between the adsorption face plate 40 and the pulling piece 30. In this case, the adsorption face plate 40 and the pulling piece 30 are coupled to the elastic portion 50 by a medium.

Referring to FIG. 4, the outer circumferential portion of the adsorption face plate 40 is coupled to the stepped portion 22 formed on the inner diameter side of the cover 20.

The step portion 22 of the cover 20, the outer peripheral portion of the adsorption face plate 40 when the pull piece 30 to the upper side by the elevating rod 32 due to the step portion 22, the The adsorption face plate 40 serves to prevent the rise with the pulling piece (30).

A through hole 25 is formed in the cover 20, and the lifting bar 32 is installed through the through hole 25.

Since the outer periphery of the adsorption face plate 40 is hooked to the stepped portion 22 of the cover 20, the lifting bar 32 inserted through the through hole 25 of the cover 20 is inserted into the cover 20. When the outer side is pulled to the upper side using the rotating member 60, only the pulling piece 30 is moved upward by the lifting bar 32 to the upper side of the cover 20.

The rotating member 60 for elevating the elevating bar 32 is formed in a general nut structure, and a thread is formed on the outer circumferential surface of the elevating bar 32. When the rotating member 60 is rotated, the elevating bar is rotated. The 32 can be easily pulled to the upper side of the cover 20.

As shown in FIG. 5, when the pulling piece 30 is moved upward in the direction of the arrow, the pulling protrusion 33 integrally formed therewith is also moved upward in the suction hole 43.

Since the pulling protrusion 33 is buried and coupled to the elastic part 50 in the suction hole 43, the pulling protrusion 33 is pulled upwards, so that the elastic part 50 also comes up, so that the suction hole ( At the end of 43, a space is generated and it becomes a vacuum state. That is, when the elastic portion 50 filling the suction hole 43 is pulled up, a vacuum space as much as it is pulled is formed at one end of the suction hole 43, and the end of the suction hole 43 is as described above. When vacuum is generated in the vacuum suction force is generated between the tile surface 100 and is firmly adsorbed.

In the present invention, as shown in FIGS. 4 and 5, the adsorption holes 43 may have a narrow trapezoidal shape at the upper side and a wide trapezoidal shape at the lower side thereof, thereby increasing the adsorption area.

In addition, since the diameter of the adsorption hole 43 on the upper side is formed small, when the elastic portion 50 formed inside the suction hole 43 is pulled by the pulling protrusion 33, the elastic portion 50 is separated from the upper side. To prevent it from going up.

As described above, a vacuum is generated between the tile surface 100 while the elastic portion 50 formed inside the adsorption hole 43 of the adsorption surface plate 40 is pulled out, and at this time, one surface of the adsorption surface plate 40 is The seal layer 42 formed thereon is in close contact with the tile surface 100 to block outside air from entering.

The elastic part 50 of the present invention may use MBR rubber or the like, or may use other materials having good elasticity and sealing properties.

In addition, the seal layer 42 formed on the adsorption face plate 40 of the present invention preferably uses silicone or polyurethane having excellent adhesion and sealing properties, but may be used with other materials having good adhesion and sealing properties. Of course.

In this manner, after the seal layer 42 surface of the adsorption face plate 40 is brought into close contact with the tile surface 100 or the like, when the pulling protrusion 33 is pulled upward, the elastic part 50 is also pulled along. At the end of 43, the tile surface 100 and the vacuum are generated while being vacuum-adsorbed and attached.

As shown in FIG. 5, a plurality of adsorption holes are formed in other portions even when vacuum is not generated due to grooves formed between tiles in the adsorption hole 43 at the boundary line 101 of the tile surface 100. Since 43 is adsorbed by generating a vacuum, it can be adsorbed firmly. In addition, in the present invention, since a vacuum is generated in the plurality of adsorption holes 43 formed in the adsorption face plate 40, the vacuum adsorption is easily carried out by being closely adhered to the tiles having embossing, the tiles having a rough surface, and the like.

That is, since the vacuum adsorption portion formed by the plurality of adsorption holes 43 is adsorbed on the tile surface or the like, the adsorption force is very excellent, and the other adsorption hole 43 parts are vacuum even when the vacuum of any one of the adsorption holes 43 is released. As it maintains the state, the overall vacuum can be easily released and maintains the suction power.

A second embodiment of the vacuum adsorption device of the present invention will be described in detail below with reference to the accompanying drawings.

Figure 6 is a view showing a second embodiment of the vacuum adsorption device of the present invention, Figures 7a, 7b is a view showing a coupling cross section of the vacuum adsorption device of Figure 6, Figure 7c is an operating state of the vacuum adsorption device of Figure 6 It is a figure which shows.

In the vacuum adsorption device of the second embodiment of the present invention, a rubber coating layer 51 having a predetermined thickness is formed on an adsorption face plate frame 41 having a plurality of adsorption holes 43. The rubber coating layer 51 has elastic restoring force, and as long as it has elastic restoring force, other materials may be used.

The rubber coating layer 51 also forms a coating layer on the inner diameter side of the plurality of adsorption holes 43 formed in the adsorption face plate frame 41.

At this time, the rubber coating layer 51 is covered only with the inner diameter surface so that the adsorption hole 43 may penetrate without filling the inside of the adsorption hole 43.

Therefore, as shown in FIG. 7A, the suction holes 43 of the suction surface plate frame 41 having the rubber coating layer 51 are provided with a plurality of pulling projections 33 formed to protrude on one surface of the pulling piece 30. Push in the direction of the arrow. A lifting bar 32 is formed to protrude from the central portion of the other surface of the pulling piece 30.

When the pull protrusion 33 is inserted into the suction hole 43 of the suction surface plate frame 41, as shown in FIG. 7B, the rubber protrusion layer 51 coated on the inner diameter side of the suction hole 43 is pulled. Since the 33 is pushed and fitted, it is sealed between the pulling protrusion 33 and the suction hole 43 so that air or the like cannot escape.

In addition, the lifting bar 32 formed on one surface of the pull piece 30 is fitted into the through hole 25 formed in the cover 20 to be coupled.

Since the through hole 25 is formed in the cover 20, when the elevating bar 32 of the pulling piece 30 is fitted into the through hole 25 and coupled thereto, the cover 20 protrudes out of the cover 20. The rotating member 60 is fitted to the lifting bar 32 that protrudes.

When the lifting bar 32 is pulled to the upper side of the cover 20 by the rotating member 60 as described above, the pulling protrusion 33 formed to protrude to the lower side of the pulling piece 30 is also pulled up and raised at the same time. .

At this time, since the pulling protrusion 33 is fitted into the adsorption hole 43 of the adsorption face plate frame 41, the rubber coating layer 51 formed on one surface of the adsorption face plate frame 41 is the tile surface 100 or the mirror. Pulling protrusions 33 are pulled in a state in close contact with the glass surface or the like.

When the pulling protrusion 33 is pulled in this way, the suction surface plate frame 41 is coupled over the stepped portion 22 formed on the inner diameter side of the cover 20, so that the pulling protrusion 33 is the suction hole 43. The upper side is pulled on the upper side), and in each of the adsorption holes 43, which are end portions of the pulling protrusions 33, the vacuum is generated by the rising of the pulling protrusions 33, and is vacuum-adsorbed and attached.

According to the second embodiment of the present invention, a plurality of adsorptions are formed in other portions even if no vacuum is generated due to the grooves formed between the tiles in the adsorption hole 43 in the boundary 101 of the tile surface 100. Since the holes 43 are adsorbed by generating a vacuum, the holes 43 can be firmly adsorbed. In addition, in the present invention, since a vacuum is generated in the plurality of adsorption holes 43 formed in the adsorption face plate frame 41, the vacuum adsorption is easily carried out by being closely adhered to the tiles having embossing or the tiles having the rough surface.

The end of the pulling projection portion 33 of the pulling piece 30 is in the thickness direction of the suction hole 43 of the suction surface plate frame 41 so as not to protrude from the rubber coating layer 51 formed on the suction surface plate frame 41. It is preferably formed so as to be located inside. This means that when the pulling protrusion 33 is formed to protrude more than the rubber coating layer 51, a vacuum may not be formed at the end of the suction hole 43, and thus the pulling protrusion 33 is positioned inside the thickness direction of the suction hole 43. It is desirable to have a length of the degree.

A third embodiment of the vacuum adsorption device of the present invention will be described in detail below with reference to the accompanying drawings.

8A is a view showing a third embodiment of the vacuum adsorption device of the present invention, and FIG. 8B is a view showing an operating state of the vacuum adsorption device of FIG. 8A.

In the third embodiment of the present invention, one or more fitting holes 38 are formed in the pulling piece 30 in the thickness direction, and the adsorption holes corresponding to the fitting holes 38 are formed in the adsorption face plate frame 41. 43 is further punctured, and further includes an adsorption rod 39 having a locking projection 37 at one end so as to pass through the corresponding adsorption hole and fit into the fitting hole 38.

Referring to FIG. 8A, while the adsorption rod 39 having the engaging projection 37 is inserted into the adsorption hole 43 from the lower side of the adsorption face plate frame 41 through the interference fit, the engaging projection 37 is fitted. It is fitted into the hole 38 and is engaged.

It is preferable that the adsorption hole 43 into which the adsorption rod 39 and the adsorption rod 39 are fitted has a diameter at the lower end thereof wider than that of the middle portion. As such, when the diameter of the lower end of the adsorption rod 39 is wide, the area in which the vacuum is generated can be widened and the adsorption force can be improved.
