Description

[Detailed description of the invention] This invention relates to a drain plate plug that can be attached to the floor, sink, etc. of bathrooms, hand wash rooms, etc.

Conventionally, the commonly used drain plate plug has been simply fitted with a metal drain plate on a metal body, but when a large amount of water is flushed, the metal drain plate lifts up and separates from the main body. It often comes off and washes away the garbage that was put in place, rendering it useless.

Furthermore, if the drain plate is clogged, it may be difficult to remove it even if you try to remove it for cleaning.

Furthermore, in this type of drainage device, a synthetic resin pipe is normally used as the drain pipe, but since the main body is made of metal, there is a problem that the adhesion at the connecting part is insufficient and dirt leaks.

This invention was devised in view of the above-mentioned circumstances, and aims to provide a drainage perforation plug that does not have these problems.

That is, in this invention, a protrusion with notches at an appropriate number of places is provided on the inside of a synthetic resin main body with a metal cover on the flange part to form a perforated plate receiving part, and the plate is fitted into the perforated plate receiving part. The mating perforated plates are provided with an appropriate number of L-shaped hooks that engage with the protrusions, and an undulating knob with a stopper at the bottom.An example of this is explained based on the drawings as follows. be.

In the figure, the drain perforation plug main body 3 is made of synthetic resin, and the flange portion 1 is provided with a reinforcing metal cover 2, and a protrusion 5 having two notches 4, 4 on the left and right is provided inside the perforation plate receiving portion. 6 was formed. The perforated plate 7 is made of metal, fits into the perforated plate receiving portion 6, has L-shaped hooks 8, 8 on both left and right sides of the lower surface that engage with the protrusion 5, and has a stopper 9 approximately in the center.
An undulating knob 10 having a shape is pivotally mounted 11.

In use, this perforated plate 7 is placed on the perforated plate receiving portion 6 with the direction of the knob 10 aligned with the index X, and rotated to engage the L-shaped hooks 8, 8 with the protrusion 5.

As mentioned above, since the drainage perforated plate plug according to this invention is of the type in which the perforated plate 7 is locked to the protrusion 5 of the main body 3, even when a large amount of water is flushed, the drainage perforated plate plug according to the present invention does not have the same effect as the conventional drain perforated plate plug. The plate 7 will not float and come off.

Further, when cleaning the perforated plate 7, the perforated plate 7 can be easily removed by raising the knob 10 and lifting the knob. In addition, since knob 10 has stopper 9,
In its natural state, it maintains a fallen state due to its own weight, protecting the knob 10 and preventing hands or objects from getting caught in the knob 10.

Furthermore, the drain plate plug according to this invention has a main body 3 made of synthetic resin, and a metal cover 2 on the flange portion 1.
As a result, the appearance after installation is the same as that of conventional products and has an excellent design.Moreover, it has the effect of reinforcing the flange part 1 and has good adhesion to synthetic resin drainage pipes, making it lightweight and inexpensive. This makes it suitable as a drainage perforation plug.
