Description

[Detailed explanation of the idea] The present invention relates to improvements in drainage traps.

Conventional drain traps of this type include those with a so-called DV joint structure and those with a tsuge joint structure, but as shown in FIG. Since the length is short, the adhesive strength is weak.

In addition, as shown in Fig. 2, in the latter case, the insertion allowance 1 can be large, but a step recess X is formed in the part of the drain pipe connection part 2 that is not inserted into the drain pipe 1, and dirt remains in this step recess X. The problem was that it was difficult to do.

Furthermore, since the trap body 3 of all conventional drainage traps is opaque, it is difficult to check for water leakage and is very time-consuming.

The present invention was developed in view of the above-mentioned drawbacks, and its purpose is to provide a long insertion distance for the drain pipe connection part into the drain pipe, to provide strong adhesive strength, and to prevent dirt from accumulating at the drain pipe connection part. There is a drain trap provided.

The present invention will be explained below with reference to examples.

FIG. 3 shows a sectional view of one embodiment, in which the trap body 3 is molded from transparent resin and has a drain pipe connection part 2 integrally protruding from the side surface.

This drain pipe connection part 2 has one end integrally connected to the side opening of the trap body 3 and has an inner circumferential surface that widens toward the other end.
It consists of a joint pipe part 4 that constitutes a V vertical joint, and a straight pipe part 5 whose one end is integrally connected to the other end of this joint pipe part 4. When connecting the drain pipe 1, the outer periphery of the tip of the drain pipe 1 is As shown in the figure, it is inserted up to the inner periphery of one end of the joint pipe section 4.

Reference numeral 6 designates a slatted upper lid, 7 an inner cylinder, and 8 an inner cylinder retaining ring body screwed onto the trap body 3.

Further, 9 is the floor surface.

In the present invention, the drain pipe connection part has a joint pipe part that has one end integrally connected to the side opening of the trap body and has a tapered inner peripheral surface that widens toward the other end. It can be connected in the same way as a so-called DV vertical joint, does not create a stepped recess where dirt can easily get stuck, and can prevent dirt from getting stuck.Moreover, it has a straight pipe part with one end connected to the other end of the joint pipe part. Therefore, it has the advantage that the insertion distance into the drain pipe can be increased and the adhesive strength can be increased.

If the trap body is made of transparent resin, it will be easier to check for water leaks.

[Brief explanation of the drawing]

1 and 2 are sectional views of a conventional example, and FIG. 3 is a sectional view of an embodiment of the present invention, in which 1 is a drain pipe, 2 is a drain pipe connection part, 3 is a trap body, and 4 is a sectional view of an embodiment of the present invention. The joint pipe section 5 is a straight pipe section.
