Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of a gasket for a water faucet mounting portion, and more particularly to a technique for preventing water leakage from a mounting hole in which a water faucet is attached.

[Background Art] Conventionally, in order to attach a water tap 3 to a mounting hole 1 of a counter 2 of a bathroom vanity or a system kitchen via a gasket 4, as shown in FIG.
The seal 4 was simply inserted between the counter 2 and the faucet 3, and the seal 4 was tightened only by the lower outer periphery of the faucet 3.
Due to variations in the method and during construction,
As shown in Figure 4, the gasket 4 easily enters the inside of the faucet 3, and when the gasket 4 enters the inside of the faucet 3 in this way, water flowing along the counter 2 flows from the mounting hole 1 to the bottom surface of the counter 2. There was a problem with water leaking.

[Purpose of the invention] The present invention was made in view of the above-mentioned problems, and its purpose is to provide a structure for the gasket of the water faucet mounting part that can prevent water leakage with a simple device. There is a particular thing.

[Disclosure of the invention] The present invention includes a gasket 4 interposed between the counter 2 provided with the mounting hole 1 and the water faucet 3 attached to the installation hole 1, and an elastic material between the gasket 4 and the water faucet 3. This is related to the structure of the gasket of the water faucet mounting portion, which is constructed by intervening an elastic gasket 5 having By configuring this structure, the above objective could be achieved. In other words, by intervening the packing 4 and the elastic packing 5 between the counter 2 and the faucet 3, the packing 4 can be adjusted to accommodate variations in the dimensions of the packing 4 and construction.
Even if the liquid enters the inside of the faucet 3, the elastic gasket 5 is located between the gasket 4 and the faucet 3 inside the outer edge of the faucet 3, and the gasket 5 is strongly pressed against the counter 2 via the elastic gasket 5. and the insertion hole 1 for the elastic packing 5.
The diameter of the elastic gasket 5 is made smaller than the diameter of the insertion hole 9 of the gasket 4, and the elastic gasket 5 interposed between the gasket 4 and the faucet 3 is compressed as the faucet 3 is attached to the counter 2. The small-diameter insertion hole 14 of the elastic packing 5 has an even smaller diameter, so that the insertion hole 14 of the elastic packing 5 can be prevented from coming off the edge of the insertion hole 9 of the packing 4 when the elastic packing 5 is in a compressed state. , and since the insertion hole 14 of the elastic packing 5 becomes small in diameter when it is compressed, it can be expected that the insertion hole 14 will come into elastic contact with the side of the faucet 3 through which it is inserted, ensuring the sealing performance by the elastic packing 5. This makes it possible to strongly suppress water leakage.

Embodiments of the present invention will be described in detail below based on the drawings.

The faucet 3 consists of a water supply part 6 and a hot water supply part 7, and the water supply part 6 and the hot water supply part 7 are operated independently or simultaneously, so that the supplied water and hot water can be mixed and discharged from the faucet 8. It is set as. The counter 2 to which the faucet 3 is attached has an insertion hole 9 for the water supply part 6 and the hot water supply part 7, and an insertion hole 10 for inserting an opening/closing handle (not shown) for opening and closing the drain hole (not shown) of the washbowl. Each is formed. A second valve is installed between the counter 2 and the water tap 3.
A substantially rectangular packing 4 shown in the figure is interposed.
Further, an elastic packing 5 having elasticity is interposed between the packing 4 and the faucet 3. As shown in FIG. 2, this elastic packing is formed into a substantially spectacle shape, and the arcuate portions at both ends may form part of an inscribed circle inscribed at both ends of the rectangular packing 4. , it may be formed to have a smaller diameter arc than this inscribed circle. The gasket 4 is made of synthetic resin such as foamed polyethylene or rubber, and has almost no elasticity. The elastic packing 5 is made of synthetic resin such as foamed polyethylene or rubber, and has sufficient elasticity. The elastic packing 5 also has an insertion hole 14 and a hole 15 formed therein. Water tap 3
is the connecting tube 11 in the water supply section 6 and the hot water supply section 7.
Insert into the insertion hole 9 and the insertion hole 14, and connect the connecting tube 11.
The water faucet 3 is firmly attached to the counter 2 by tightening a nut 13 to the male threaded portion 12 on the outer periphery of the water tap. In this case, as shown in FIG. 1, the diameter of the insertion hole 14 of the elastic packing 5 is made smaller than the diameter of the insertion hole 9 of the packing 4.

According to such a configuration, by interposing the packing 4 and the elastic packing 5 having elasticity between the counter 2 and the water faucet 3, the packing 4 can be easily adjusted due to variations in the dimensions of the packing 4 or variations in construction.
Even if a part of the outer edge part enters inside the outer edge of the faucet 3, the seal 4 can be strongly pressed inside the outer edge part via the elastic packing 5, and water leakage is strongly suppressed.

``Effect of the invention'' In short, the present invention uses a packing and an elastic packing between the counter and the faucet. Even if it enters the inside of the faucet at the outer edge, the elastic gasket is between the gasket and the faucet, and the elastic gasket can be strongly pressed against the counter via the elastic gasket. Since the diameter of the insertion hole is smaller than that of the gasket, the elastic gasket inserted between the gasket and the faucet is compressed as the faucet is installed on the counter.
The small diameter insertion hole of the elastic packing becomes even smaller in diameter, so that when the elastic packing is compressed, the insertion hole of the elastic packing can be prevented from coming off the edge of the insertion hole of the packing, and the insertion hole of the elastic packing can be prevented from coming off the edge of the insertion hole of the packing. Because the pore becomes smaller in diameter when compressed,
It can also be expected to come into elastic contact with the water faucet that is inserted into the insertion hole, which has the advantage of ensuring the sealing performance of the elastic packing and strongly suppressing water leakage.
