Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packing for connecting the drain port of a flush toilet, which is mainly used when connecting the drain port of a flush toilet to the socket of a drain pipe.

In order to connect the drain port of a flush toilet and the socket of the drain pipe, soft putty or the like was filled between the outer surface of the drain port and the inner surface of the socket. Due to the distortion in the mouth part, there is a problem that not only is workability poor, but also it is almost impossible to join tightly.There is also a problem that the socket part of the drain pipe cannot be accurately and easily joined to the drain port part of flush toilets. Therefore, there is a strong demand for the development of packing for connecting the drain port of flush toilets, which can accurately and easily connect the socket of a drain pipe to the drain port of flush toilets.

The present invention was completed for the purpose of packing for connecting the drain port of flush toilets in response to the above-mentioned demands, and as shown in the illustrated embodiment, a plurality of short flanges 1 are provided on the outer peripheral surface. At the tip of a short cylindrical main body 2 made of an elastic material such as rubber, a short cylindrical part 3 made of the same material whose inner diameter is slightly larger than the inner diameter of the main body 2 is attached to the inner peripheral surfaces of the main body 2 and the short cylindrical part 3. The short cylindrical portion 3 is connected to the slanted surface 4 between the short cylindrical portion 3 and the short cylindrical portion 3 at the tip thereof.
It is characterized by having an inner flange 5 and an outer flange 6 made of the same material.

In a toilet constructed in this way, first, a short cylindrical main body 2 made of an elastic material such as rubber and a short cylindrical part 3 connected to the tip of the main body 2 are arranged in the discharge cylinder part B of the flush toilet A. Using this, the inner flange 5 provided at the tip of the short cylinder part 3 is fitted to a position where the mouth edge of the discharge cylinder part (B) comes into contact with the inner flange part 5, so that it is slightly inside from the mouth edge of the discharge cylinder part (B). If the main body 2 is fitted into the concave groove C, even if there is distortion in the discharge cylinder B, the main body 2 will be connected to the tip of the main body 2 through the inclined surface 4 with an inner diameter slightly larger than the inner diameter of the main body 2. Since the short cylinder part 3 is in the state shown in FIG. 2 in which the outer periphery of the distal end of the discharge pipe part B is properly enclosed, the socket part D of the drain pipe is then inserted into the discharge pipe with the packing fitted as described above. When it is fitted into the main body 2, as shown in FIG. The sealing effect of the outer flange portion 6 and the short flange portion 1, which bend toward the base due to elasticity and attempt to return to their original shape, and the sealing effect of the outer flange portion 6 and the short flange portion 1, which are interposed between the mouth end of the ejection tube portion B and the socket portion D, Due to the sealing effect of the inner flange portion 5, the drain port portion is properly sealed, and the socket portion D is connected to the drain tube portion B. Furthermore, the only work required during this time is to fit and push the packing according to the present invention into the discharge tube part RO, and then to fit and push the socket part 2 of the drain pipe, so the joining work is extremely simple. Even an unskilled person can easily connect the drain pipe. In addition, it is preferable that both the short flange part 1 and the outer flange part 6 have one surface, that is, one surface on the front side, made into a tapered surface as shown in the figure so that the thickness becomes thinner toward the tip of the flange. By doing so, the fitting operation of the socket part 2 can be carried out more smoothly, and the sealing effect can be further enhanced.

Therefore, the present invention has great practical value as a packing for connecting the drain port of flush toilets, which allows a drain pipe to be connected accurately and easily to the drain pipe of flush toilets.
