Description

[Detailed explanation of the idea] The present invention relates to a cleaning port drainage fitting.

For example, in areas where the floor surface is flushed with water when cleaning, such as tiled floors or toilets, garbage may be poured in with water through the cleaning port provided on the floor surface, or the dirty water from cleaning may be flushed with water. is being drained.

However, conventional cleaning port drainage fittings are simply cylindrical metal fittings with a lid plate screwed onto the top, so when the surrounding area is hardened with cement to install it, the metal fittings are deformed by the shrinkage force when the cement solidifies. In some cases, the lid plate cannot be screwed together, and in particular, although the drainage effect is good, large debris tends to flow in with it, and the drain pipe often becomes clogged with debris, which requires considerable repair work. It took a lot of work.

The present invention relates to cleaning port drainage fittings, and is an attempt to solve the above-mentioned problems of conventional ones.

The purpose of this is to create cleaning port drainage fittings that are strong enough to prevent deformation due to shrinkage force caused by cement solidification when installed, and that can prevent large debris from flowing in and prevent drain pipes from clogging. That's what we're trying to offer.

The invention will be explained below by means of illustrated embodiments.

Reference numeral 1 denotes a drain fitting main body, which is a short cylindrical portion that can be engaged into the opening of the drain pipe 2, and has a flange portion 3 on its upper outer periphery.

A strainer part 4 having a large number of through holes 5 is formed integrally with the main body 1 at a substantially intermediate position inside the drain fitting main body 1, and is connected to the inner periphery of the main body 1 near the outer periphery of the upper surface of the strainer part 4. , it features a shallow annular groove 6 for engaging the backing.

A female screw portion 7 for screwing the cover plate is formed on the inner periphery of the upper portion of the main body 1.

Reference numeral 8 denotes a ring-shaped backing, the lower half of which is engaged in the groove 6.

Reference numeral 9 denotes a cover plate, which has a male threaded portion 10 on its outer periphery and is removably screwed into the female threaded portion 7 of the main body 1.

Its thickness (height) is such that when the lower surface contacts the upper surface of the backing 8 in relation to the backing 8, the upper surface of the cover plate 9 and the upper surface of the main body 1 are approximately on the same plane.

Note that 11 is a hook hole for rotation formed on the top surface of the lid plate.

12 indicates the floor surface. Next, the effects of the cleaning port drainage fitting of the present invention will be explained using the above embodiments.

First, (1) When installing a drainage fitting, the one of the present invention has a strength corresponding to the shrinkage force during cement solidification.

Conventional fittings have a short cylindrical shape with a flange, so when the fitting is installed on the floor, it may be deformed by the shrinkage force when the cement surrounding it solidifies, making it impossible to hold the lid plate in place. Ta.

However, in the present invention, the strainer part is provided in the middle part of the metal fitting body, which increases the strength against the force from the surrounding part, and even if shrinkage force is applied when the cement solidifies, it is not supported by the strainer part. There is no deformation and the lid plate can be screwed together smoothly.

In addition, the drainage fitting of this invention can prevent the drainage pipe from becoming clogged with debris.

The conventional type has a short cylindrical shape with a flange, so in places where the floor surface is flushed with water when cleaning, such as tiled floors or toilets, large debris can flow in with the water and clog the drain pipe. This frequently occurred and required a considerable amount of effort to repair.

However, in the present invention, a strainer part is provided in the drain fitting, so that it is possible to prevent large pieces of dirt from flowing into the drain fitting, thereby preventing the drain pipe from becoming clogged with dirt.

Moreover, if the strainer part is formed integrally with the metal fitting main body as in the above embodiment, there is no possibility that the strainer part comes off from the main body when removing dust attached to the strainer part.

In addition, if the lower half of the backing is engaged in the groove formed in the strainer part as in the above embodiment, the backing will not come off inadvertently when removing dust attached to the strainer part. few.

Further, in the above embodiment, the strainer part is integrally molded with the main body of the drain fitting, but the strainer part is not limited to this, and the strainer part may be placed separately from the main body on an annular step formed inside the main body. In that case as well, the same effect as above is achieved.

Claims (1)

[Scope of utility model registration request] This cleaning port drainage fitting is formed by screwing a lid plate 9 removably into a short cylindrical drainage fitting main body 1 having a flange 3 at the top, and has a large number of through holes 5 inside the main body 1. A cleaning port drainage fitting characterized in that a strainer part 4 is provided, and a backing 8 is interposed on the upper surface near the periphery of the strainer part 4 so as to be able to come into contact with the lower surface of the lid plate 9.
