Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) The present invention relates to a joint, particularly to a pipe joint for water purifier construction, which is used when the water purifier is directly attached to a sink.

(Prior Art) Among the conventional water purifiers that have been attached and used, there is one in which the main body of the water purifier is installed inside a sink.
In this case, since the water purifier is provided inside the sink, the water purifier does not get in the way at the time of housework and the appearance is good.

In such construction, as a method of branching the water supply to the water purifier, if there is a branch or pipe outlet in the sink, or branch the upper water pipe on the sink,
There is a method of introducing it inside the sink.

The work is easy if there is a branch or a pipe outlet inside the sink, but there are practically few sinks with such pipes. For this reason, there are many construction examples in which piping is introduced from the upper part of the sink.

In the case of construction in which piping is introduced from the upper part of the sink, generally, for example, the nipple 11 shown in Fig. 3 is used, and the wall surface of the sink is used.
In general, a hole 13 is bored in the vicinity of 12, and the nipple 11 is inserted into the hole 13 from below the sink, and the nipple 11 is held and tightened by a nut 14 to fix the nipple 11 to the sink.

(Problems to be Solved by the Invention) As described above, when the conventional normal nipple 11 is used for construction, there are the following inconveniences.

That is, since the nipple 11 is inserted from under the sink, the nipple is
When tightening the nut 14 while holding 11, keep the nipple
The work of tightening the nut while holding 11 is difficult to work alone because the construction site is behind the sink.
There was a problem that workability was poor.

Also, because the nipple 11 does not have an appropriate and sufficient size, the plate surface of the sink is clamped with the nut 14, and the thickness of the plate of the sink makes it difficult to connect the pipe to be connected to this nipple 11 after fixing. There was also a problem that it could be uncertain.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a pipe joint having good workability and a good appearance after the work.

Configuration of the Invention (Means for Solving the Problem) The present invention provides a flow passage inside a cylindrical joint body having a predetermined length with a thread cut on the outer periphery, and a lower portion is provided near the upper side of the joint body. A fixed body having a large-diameter flange is fixed to the fixed body, and the a portion of the joint body exposed above the fixed body is used as a connection screw portion, and the lower portion of the fixed body, the b portion, is a through hole of the plate body of the sink. The joint body is fixed to the lower surface of the plate body of the sink through the washer and the packing with a nut screwed from below the joint body, and the joint body exposed below the nut is used as the connection screw portion, A pipe joint device for water purifier construction, characterized in that a connection screw part is connected to a pipe of a tap, and a connection screw part is connected to a pipe of a water purifier housed in a lower part of a sink.

(Operation) The present invention is configured as described above, and the joint main body is inserted from above into the through hole penetrating the plate near the wall surface of the sink. A fixed body having a collar portion with a large diameter is fixed to the lower part of the joint body toward the upper side. Therefore, when the joint body is inserted into the hole, the lower side of the joint body, which has been long-threaded, protrudes below the plate body, so fixing work with nuts etc. is good at locations where it is difficult to attach sinks, etc. Act to be able to.

Also, since the collar part of the fixed body is formed with a larger diameter than the joint body, it is possible to hide it securely even if the hole penetrating the plate body at the attachment site such as the sink is roughly formed. It works as it can.

Furthermore, in the case where the joint body is manufactured by forming screws in the same direction on the outer circumference, after installing the joint body, do not use the branch pipe from the water supply or the connection pipe to the water purifier with the reverse thread. Good, the number of parts can be reduced, and when a female screw screwed inside the fixed body is screwed into the joint body and the screwing position is located on the upper side of the joint body and fixed with an adhesive, screw Since the position can be selected arbitrarily, it works so that it can be used as a pipe joint according to the condition of construction.

Further, when the fixed body is decorated, it acts to prevent the appearance of a sink, a system kitchen or the like from being adversely affected.

(Example) An example in which the pipe joint of the present invention is applied to a sink will be described below with reference to the drawings.

Cylindrical joint body 1 made of appropriate material such as iron
A screw is screwed in the same direction on the outer periphery of the. The joint body 1 may be a commercially available pipe having a threaded outer periphery.

A fixed body 2 made of an appropriate material is screwed onto the joint body 1.

The screwing position should be on the upper side of the joint body 1 as shown in FIG. 1, for example, a = 10 to 20 mm away from the upper end of the joint body 1,
The fixed body 2 is fixed by an appropriate means such as an adhesive so that the upper end of the fixed body 2 comes to the top. Further, it is preferable that the flange portion 3 of the fixed body 2 and the lower end of the joint body 1 are formed with a distance of b = 100 to 200 mm.

The fixed body 2 is provided with a flange portion 3 having a large diameter on the lower side thereof. The fixed body may be nickel-plated or the like when it is used for a stainless steel sink, etc., though it depends on the place of use.

In FIG. 1, 4 is a nut for fixing the joint body 1 after inserting it into the through hole 6 of the plate 5 of the sink, 7 is a washer, and 8 is a packing made of an appropriate material such as rubber. Therefore, water on the sink is prevented from flowing out of the through hole 6 and leaking into the inside.

Further, in FIG. 2, reference numeral 9 indicates a tap of a water tap, and 10 indicates a water purifier.

 Next, a construction example of this embodiment will be described.

The joint body 1 is inserted from above so that the fixed body 2 is located above the through hole 6 penetrating the plate body 5 near the wall surface of the sink, and the flange portion 3 covers the through hole 6 of the plate body 5.

Next, the joint body 1 is fixed to the plate body 5 with the nut 4 from below the plate body 5 of the sink. At this time, the packing 8 is fixed between the collar portion 3 and the plate body 5, and the nut 4 and the plate body 5 are fixed via the washer 7 and the packing 8.

The connection screw portion 1a exposed at the upper end of the joint body 1 fixed in this way is attached to the branch portion 9 of the tap of the water pipe.
The connection screw portions 1b exposed at the lower end of the water purifier 10 are connected to the water purifier 10, and the tap water is supplied to the water purifier 10 through the inside of the joint body 1.

In addition, in the embodiment, the example in which the screw has one direction is described. This is because the thread cutting work is simple and the position of the fixed body 2 can be arbitrarily selected.
The present invention is not limited to this, and it goes without saying that the upper and lower threads of the joint body 1 may be formed as reverse threads.

In addition, in the embodiment, an example of using between the branch part of the water supply and the water purifier has been shown, but the present invention is not limited to this. It may be used for pipe fittings for other uses that are used for the portion of thickness.

Advantageous Effects of the Invention The present invention has the above-described configuration and operation, and when the water purifier main body is installed inside the sink when the water is introduced from the tap outside the sink, it penetrates the sink. In addition to the simple and easy piping work, the single joint can be used regardless of the thickness of the sink plate, and a pipe joint having a good appearance after the work can be provided.

In addition, the fitting itself is suitable for the location where it is installed, the screw length can be easily set, and the configuration is simple. In particular, the fitting body can be a general-purpose pipe that is commercially available, so it can be produced at low cost. It has excellent effects such as possible.
