Description

[Detailed description of the device] 【Technical field】

The present invention relates to the structure of a square joint such as a square elbow connected to a water collector.

[Background technology]

When connecting the water collector 1 ′ and the rectangular joint A ′ such as the square elbow, the rectangular tubular drain port 2 is provided at the bottom of the water collector 1 ′.
Is provided and the connecting tubular portion 3 above the joint A ′ is fitted and fixed to the outer periphery of the drainage port 2.
It is difficult to use locking means such as turning and hooking the joint A'because of the fitting of the square shapes, and therefore,
As shown in FIG. 5, this is performed by bonding with an adhesive 6. However, if the connection is made by the adhesive 6 as described above, the joint A'cannot be removed from the water collector 1'after the joint A'is attached to the water collector 1 ', and disassembly and cleaning or the like is not possible. There is a problem in that it cannot be carried out, and there is a problem in that it is necessary to hold the joint A ′ before the adhesive 6 is hardened during the construction, which is troublesome. In order to solve such a problem, actual development Sho 58-16
As disclosed in Japanese Unexamined Patent Publication No. 8628 and Japanese Utility Model Laid-Open No. 53-125927, a locking structure of a through-hole-shaped locking hole and a locking projection is also proposed, but a through-hole-shaped locking hole and locking projection. In the case of locking with, the through locking is performed even when the orientation of the joint with respect to the water collector is wrong, and when changing the orientation of the joint, it is difficult to pull out the locking protrusion from the locking hole, There was a problem that it was difficult to change the orientation. Further, there is a problem that rattling is likely to occur in the locked state because of the locking configuration of the through-hole-shaped locking hole and the locking projection.

[The purpose of the device]

The present invention has been made in view of the above circumstances, and its purpose is to provide a structure of a rectangular joint such as a rectangular elbow connected to a water collector without using an adhesive. The purpose of the invention is also to enable detachable connection to improve workability, and also to easily change the orientation of the joint with respect to the water collector and to avoid rattling in the connection.

[Disclosure of device]

The present invention has a structure of a joint in which a rectangular tube-shaped drainage port 2 at a lower portion of a water collector 1 is fitted with a rectangular tube-shaped connecting tube portion 3 at an upper end thereof to be connected, and A thin wall portion 5 for locking which is pierced by the locking projection 4 on the outer surface of the drainage port 2 when fitted to the drainage port 2 of the water container 1 is provided, and the above-mentioned object is achieved by this configuration. It is a thing. That is, when the adhesive cylinder portion 3 of the joint A is fitted into the drainage port 2 of the water collector 1, the locking thin portion 5 is pierced by the locking projection 4, and the joint A is connected to the water collector 1. Therefore, the rectangular joint 5 can be connected to the water collector 1 without using the adhesive 6, and the locking projection 4 can be detached by pressing the locking projection 4. As a result, the water collector 1 and the joint A can be disassembled, which does not hinder cleaning or the like. Hereinafter, the present invention will be described with reference to the embodiments shown in the accompanying drawings. The water collector 1 is a synthetic resin molded product, and has a rectangular tubular shape that is open at the top and bottom, and a rectangular tubular drainage port 2 having a smaller diameter than the main body is provided in the lower portion. One locking projection 4 having a triangular shape in a side view is provided on each of the outer surfaces of the opposite side pieces of the drain port 2 of the water collector 1.
Is projected. The joint A is a square elbow, the connecting tubular portion 3 at the upper end has a diameter larger than that of the main body, and the engaging thin wall portions 5 are provided on the opposite side pieces. In the embodiment shown in FIG. 1, the locking thin-walled portion 5 has a concave inner surface.
Are formed. Then, the connecting cylinder portion 6 of the joint A is connected to the drain port 2 of the water collector 1.
, The locking projection 4 on the outer surface of the drainage port 2 is fitted into the locking thin portion 5 and temporarily fixed (FIG. 3 (b)), and then the locking projection 4 is locked. The part 5 is pierced to be permanently fixed (Fig. 3 (c)). By pressing the locking projection 4, the locked state with the broken thin wall portion 5 for locking is released, and the joint A can be separated from the water collector 1. The locking thin-walled portion 5 may be formed by recessing the outer surface of the connecting cylinder portion 3 as shown in FIG. In the present invention, the joint A includes not only the elbow as in the above embodiment, but also a joint, a cosmetic wedge gutter, etc. It is a thing.

[Effect of device]

According to the present invention, since the connecting cylinder is provided with the locking thin portion that is pierced by the locking projection on the outer surface of the drain when it is fitted into the drainage port of the water collector, If it fits in the drainage port of the water collector, the locking thin portion is pierced by the locking protrusion, and the joint is connected to the water collector.
A square joint can be connected to the water collector without using an adhesive. Moreover, by pressing the locking protrusion, the locking protrusion can be disengaged, and the water collector and the joint can be disassembled. Since there is no hindrance to the connection, and furthermore, when the drainage port of the water collector is fitted into the connection cylinder part, a thin locking part is provided that is pierced by the locking projection on the outer surface of the drainage port. , When connecting the fitting to the water collector, if the fitting is inserted in the wrong orientation with respect to the water collector, the locking thin part can prevent the protrusion of the locking projection, and there is no locking thin part. In this case, it is possible to prevent the locking projection from easily entering and removing the fitting in order to change the direction of the fitting, making it difficult to pull out the locking projection and avoiding the trouble of changing the orientation of the fitting. There is an advantage that you can. Moreover, since the locking projection is locked by breaking through the locking thin portion, it is possible to avoid rattling in the locking of the locking projection.
