Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a protective device for the water supply stop valve of a low tank for flushing toilets. It is related to the stopper.

[Prior Art] A water stop valve for a low tank is installed in the middle of the water supply pipe to the low tank, and is used to shut off water during installation or repair of the low tank, or to reduce the pressure of tap water supplied to the low tank. Used for adjustment, etc.

Conventionally, once the opening of this type of stop valve has been adjusted to suit the type of toilet being used in accordance with the tap water pressure at the site where the toilet is installed, it cannot be adjusted again unless an accident related to the water supply occurs. There's no need to do it.
Furthermore, if the opening degree is changed inadvertently due to mischief or the like, problems such as loud water supply noise or prolonged water supply may occur.

For this reason, unlike the handle of a general water faucet, the operation part of this type of water stop faucet has the tip of the shaft of the spindle for adjusting the opening exposed to the outside, and a groove is carved into the tip. The opening degree is adjusted by inserting and operating a flat head screwdriver into the groove.

[Problems to be solved by the invention] As mentioned above, the spindle tip of the water stop valve has no handle and is sharp. This type of water stop valve is installed exposed on the inner wall surface of the toilet. For this reason, in the case of Japanese-style toilets where the stop valve is located above the toilet bowl, parts of the body may hit and cause injury when the body moves up and down during use. The situation was ripe. In particular, when used by young children, there is a high risk of injury due to hitting the stop valve's spindle with the forehead.

[Means for solving the problem] The present invention has been devised in view of the above points, and its structure is made of materials such as rubber and synthetic resin, and has a water stop function to adjust the amount of water or to stop water. It is formed into a generally bowl-shaped outer shape so as to cover the spindle of the stopcock and a nut for fixing the spindle, and has an insertion hole for a screwdriver for operating the stopcock at its top.

[Function] According to the stop valve protector of the present invention, even if a toilet user or the like hits his/her head against the stop valve, no injury will occur due to the elasticity of the protector.

Moreover, the opening degree of the water stop valve can be adjusted using a screwdriver while the protective equipment is attached to the water stop valve.

[Example] Examples will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view showing the structure of a protective device according to an embodiment of the present invention, and FIG. 2 is an overall side view showing the state of use thereof.

The protective gear 9 in this embodiment is made of a soft material such as rubber or synthetic resin, and has a substantially bowl-shaped outer shape. Specifically, a nut 5 for fixing a spindle 3 formed continuously to an on-off valve (not shown) of a water stop valve 2 that supplies water to a low tank 1 to a water stop valve main body 4, and a tip 3 of the spindle 3. The outer shape is approximately bowl-shaped and covers the .

This protector 9 has a fitting cavity 6 formed therein, and a peripheral edge 7 has a protruding edge 8 slightly protruding inward.

Also, a screwdriver insertion hole 1 is provided at the top 10 of the protective equipment 9.
1, the water stop valve 2 can be opened and closed with the protective equipment attached in the event of a water supply accident. Note that the insertion hole 11
The protector 9 is made thicker so that it does not directly contact the tip 3' of the spindle 3 when it comes into contact with a human body.

In the present invention, in order to facilitate fitting into the water stop valve 2, a cut portion consisting of a plurality of grooves extending in the insertion/removal direction of the water stop valve is formed on the inner circumferential surface of the protector 9. Good too. In the figure, 13 is a wall surface, 14 is a cleaning pipe that leads water in the low tank 1 to the toilet bowl 15, and 16 is a water supply pipe.

[Effects] As explained above, since the present invention has an extremely simple structure, it can not only be provided at low cost but also be safe for use by infants and the like. Furthermore, in cases where a large number of people use the system, such as in a public restroom, it is possible to prevent water supply noise caused by mischievous operation of the spindle or poor cleaning due to insufficient water volume when water is continuously used for a long time. Furthermore, in the case of a seated toilet, it can be used as a stopper when the toilet seat is used in an upright position, and this is an extremely useful device as it can prevent damage to the toilet seat.
