Description

[Detailed description of the invention] This invention relates to a drain plate plug that can be attached to the floor or sink of a bathroom, washing machine storage area, etc.

Drainage plate plugs currently on the market consist of a perforated plate receiving part on a flange that has a drain pipe attachment part and a perforated plate removably attached to this perforated plate receiving part. There was a drawback that cockroaches, worms, slugs, etc. could enter the room through the drain pipe through the holes provided.

Therefore, this invention aims to provide a drainage perforation plug that is free from the risk of these animals entering the drain.

That is, this invention provides a drainage perforated plug consisting of a flange-shaped perforated plate receiving part having a drain pipe mounting part and a perforated plate removably provided in the perforated plate receiving part, and an intermediate receiving part is provided in the drain pipe fitting part. The present invention is characterized in that a fine-mesh inner screen is fitted into the inner receiving part, and a knob that reaches the perforated plate is provided on the inner screen.

An embodiment of this invention will be described below based on the drawings.

In the figure, reference numeral 1 denotes a known drainage perforated plug comprising a flange-shaped perforated plate receiving portion 2 at the upper end, a drain pipe attachment portion 3, and a perforated plate 4 detachably provided on the perforated plate receiving portion 2.

The drain pipe attachment part 3 is formed into a tapered cylindrical shape so that the diameter gradually decreases toward the bottom, and a cylindrical adapter 5 made of synthetic resin and having a required wall thickness is fitted on the outside thereof. Like the drain pipe attachment part 3, this adapter 5 also has a tapered cylindrical shape so that the diameter becomes smaller toward the bottom.

A middle receiving part 6 that also serves as a stopper is integrally formed on the inner surface of the lower part of the adapter 5, and even when the middle receiving part 6 is installed fully in the drain pipe attachment part 3, it is located at a flange-like perforated plate receiving part. 2, a gap P into which the tip of a screwdriver can fit is formed.

A fine inner mesh 7 is fitted into the stepped portion 6a of the inner receiving part 6, and the inner mesh 7 is provided with a knob 8 long enough to reach the upper perforated plate 4.

As described above, the drainage perforation plate plug according to this invention has a fine inner mesh 7 fitted into the inner receiving part 6 provided in the drain pipe attachment part, and a knob 8 that contacts the perforation plate 4, so that it is normally used. Since the perforated plate 4 is engaged with the perforated plate receiving part 2 by the hooks 4a, 4a, it is not restrained in the fitted position and does not move, which prevents the intrusion of cockroaches, worms, slugs, etc., and also prevents fine dust from entering. It has the effect of preventing the flow of water.

If the inner screen 7 becomes clogged, the long knob 8 is provided so that the inner screen can be easily removed and the dirty garbage can be removed without touching it, and can be used as a drain plate plug. It is suitable.

In this embodiment, the middle receiving part 6 is provided on the adapter 5, but it goes without saying that it may be provided on the drain pipe attachment part 3 of the drainage perforated plug 1.

Note that this embodiment is designed so that a large diameter drain pipe can be connected when the adapter 5 is attached, and a small diameter drain pipe can be connected when it is removed, but the design is not limited to this. Of course.
