JPH082211Y2 - Mounting structure of drain valve in toilet bowl water tank - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a drain valve mounting structure in a toilet bowl water tank.

(Prior Art) A conventional mounting structure is proposed in, for example, Japanese Utility Model Publication No. 59-5103. (See FIG. 4) In this configuration, the shaft portions 51, 51 are provided on the left and right sides of the base portion 50, respectively, while the bifurcated leg member 53 of the drain valve 52 is provided with the shaft holes 54, 54, respectively. The drain valve 52 is attachable to the pedestal portion 50 by extending the bifurcated leg member 53 to the left and right and fitting the shaft holes 54 from the left and right of the shaft portion 51.

(Problems to be solved by the invention) By the way, the drain valve is periodically replaced because it deteriorates with age and its water-stopping ability decreases.

In this respect, in the above-mentioned conventional one, the drain valve attachment / detachment operation is a horizontal movement, and the attachment / detachment work in a tank having a narrow cross-sectional space is considerably limited and troublesome.

The present invention was developed in consideration of such circumstances, and an object of the present invention is to provide a drain valve mounting structure in which the drain valve can be replaced by a vertical detaching operation.

(Means for Solving Problems) In the drainage valve mounting structure of the toilet bowl water tank of the present invention, in the toilet bowl water tank in which the drain port on the bottom surface of the tank is opened and closed by the drain valve, It consists of a base part to be placed, a drain valve to which a leg part is attached to this base part, and a presser part that fixes this leg part to the base part, and the base part and the drain valve leg part have a vertical direction. A receiving part and a protruding part that are fitted to each other are provided, and a through hole is formed in the holding part in the up-down direction, and a screw is inserted into this through hole and screwed into the screw hole of the base part. It is characterized in that the drain valve can be attached to the portion in the vertical direction.

(Operation) To attach the drain valve to the base, attach the legs of the drain valve to the base by fitting the protrusions and the receivers of the both of them up and down, and then cover the foot from the top of the leg. , Insert the screw into the through hole of the holding part from above and screw it into the screw hole of the base part, and press the foot part of the drainage valve to the base part with the holding part to attach and fix it.

Then, in order to remove the drain valve from the base portion, the drain valve can be removed in the upward direction by the procedure opposite to the above-described mounting order.

As a result, the drain valve can be attached and detached in all vertical operations.

(Embodiment) Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

In the tank 1, a base portion 3 is bulged to the side of the drainage port 2 on the inner bottom surface 1a, and the leg portion 5 of the drainage valve 4 is screwed and fixed to the base portion 3 with a holding portion 6. .

At the left and right ends of the base part 3, the receiving parts 7, 7 are vertically recessed,
Screw holes 8 and 8 are vertically provided between the receiving portions 7 and 7.

The drain valve 4 has a leg portion 5 formed in a bifurcated shape on the base side of the valve portion 9, and a projection 10 that fits into the receiving portion 7 is vertically provided on the lower surface of the leg portion 5. , 10 are attached to the receiving parts 7, 7 in a fitting manner.

Through holes 11 and 11 are vertically penetrated through the central portion of the holding portion 6, and fitting portions 12 and 12 into which the leg portions 5 can be fitted are provided on the left and right bottom sides, respectively. The leg portion 5 is covered from above so that the leg portion 5 is fitted in the fitting portions 12, 12.

The screws 13 and 13 are respectively screwed into the screw holes 8 and 8 through the through holes 11 and 11, respectively, to fix the holding portion 6 to the base portion 3 and to fix the leg portion 5 in the fitting portions 12 and 12 downward. The protrusions 10, 10 on the lower surface of the leg portion 5 are held in the receiving portions 7, 7 in a fitted state by being pressed against.

Thereby, the drain valve 4 has the leg portion 5 fixed, the valve portion 9 can open and close the drain port 2, and the drain valve 4 can be vertically attached and detached by tightening or loosening the screw 13. is there.

Further, in the above embodiment, the tank 1 is made of synthetic resin in which the base portion 3 and the drainage port 2 are integrally molded by a molding die, but may be made of earthenware and is not limited.

The drain valve 4 is preferably made of rubber, and the holding portion 6 is made of synthetic resin or earthenware.

Further, when the base part 3 is a synthetic resin molded product integrally molded with the drainage port 2 by a molding die, the mounting structure of the present invention can be adopted for the tank 1 made of ceramics. It does not change anything.

(Effect of the Invention) Therefore, the present invention has the following advantages.

The drain valve can be replaced in all up and down operations, and can be quickly and easily performed in a narrow cross-section space tank.

All you have to do is to fit everything up and down, except for screw operation, so no special technique is required and any number of people can replace it.
