Description

[Detailed Description of the Invention] The present invention relates to a socket mounting structure for a drainage basin.

Conventionally, in order to attach a drain pipe or socket to a drainage basin body made of synthetic resin foam, a through hole 6 is drilled in advance in the peripheral wall of the drainage basin body 5 using a hole saw, etc., as shown in Fig. 1. After fitting the seal ring 7... to the periphery of the ring 7...
A drain pipe 8, etc., was inserted inside, but this installation method required a lot of work and had the disadvantage that the seal ring deteriorated over long periods of use.

The present invention was developed to solve these drawbacks, and consists of a drainage basin body made of hard synthetic resin foam including an adjuster cylinder, and a drain basin body that can be easily attached to the peripheral wall of the drainage basin body by screwing. It is characterized by being combined with a socket body of a novel structure that allows for

A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. Figure 2 shows a state in which a socket body 2 is attached to a drain basin body 1 by screw insertion, and reference numeral 11 denotes a drain basin body. A drainage basin main body part 12 made of foamed resin such as polypropylene, which constitutes the bottom part of the drainage basin, is connected to an engaging part 11a formed on the upper part of this basin main body part 11 as necessary in order to freely increase or decrease the capacity of the drainage basin. This is an adjuster cylinder body that is engaged and connected.

The socket main body 2 is molded into a rectangular cylinder shape using synthetic resin, and the drain basin main body 1 is located in the middle of the socket body 2.
A tapered threaded protrusion 2a formed in a widening shape so that the starting end located on the insertion direction side becomes tapered.
It is screwed into a through hole 3 bored in the peripheral wall surface of the drainage basin main body part 11.

FIG. 3 shows another embodiment of the socket main body 2. This socket main body 2 is formed into an elbow shape, and in the middle thereof there is a starting end portion located on the insertion direction side of the drainage basin main body 1. Only the threaded protrusion 2b has a tapered shape, and the other parts have a threaded protrusion 2a with threads formed to have the same diameter, and the starting end 2b of the threaded protrusion 2a has about two tapered threaded threads. This facilitates screw insertion and attachment to the drainage basin main body 1.

FIG. 4 is a diagram showing still another embodiment of the socket body, in which the threads are formed in a tapered shape similar to the case in FIG. A flexible tube 4 that can be expanded, contracted, and bent freely is provided in the outer part.

As described above, the socket main body 2 that can be applied to the drainage basin mounting structure of the present invention can be implemented in various modifications, and in addition to the above-described
As shown in the figure, it may be formed into a universal joint type in which the bending angle can be freely changed around the connecting portion 2c. Further, the socket body having the above characteristics may be formed by directly providing the above-mentioned threaded protrusion on the drainage pipe attached to the drainage basin body. In addition, it goes without saying that all types of drainage basins can be used depending on the purpose of use, and the socket bodies formed accordingly have threaded protrusions that are the same as or better than the drainage basin body. Needless to say, any shape can be used as long as it is made of a hard material.

Therefore, when attaching the socket body to the peripheral wall of the above-mentioned drainage basin, for example, after drilling an appropriate through hole with a hole saw or the like in an appropriate place in the drainage basin, adjuster cylinder body, etc., insert the socket body into this through hole. If you insert the socket and screw the thread of the socket into the periphery of the through hole, there will be no gap in the peripheral wall of the drainage basin because the threaded part of the socket main body is tapered at the starting end. It can be easily installed, and there is no need to use a seal ring, making the installation process extremely easy.
