Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a faucet that is easy to install.

(Conventional technology) Conventionally, in order to install a faucet on a counter such as around a sink, a mounting thread provided at the installation end of the faucet body was inserted into a mounting hole made at the mounting position of the counter. After that, a tightening nut was screwed into the mounting thread that penetrated the back side of the counter, and the counter was tightened and fixed.

However, since the bottom of the sink and water supply piping are often installed close to the back of the counter, when tightening the tightening nut after installing the water dispensing device, it is difficult to use a spanner or the like to tighten the tightening nut. The bolts were bumping into each other and were difficult to tighten, making the workers cry.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a faucet that is easy to install.

(Technical Problem) The problem described above is that the faucet main body must be fixed by tightening a tightening nut located under the counter where there are many obstacles.

A technical problem of the present invention is to enable tightening of a tightening nut and a mounting screw from a location free of obstacles.

(Means for Solving the Problems) The faucet of the present invention takes the following measures to solve the above-mentioned problems.

A mounting bolt is passed through the faucet main body and protrudes from the mounting end of the faucet main body, and a tightening nut is screwed onto the protruding end, and the nut has an outer circumferential portion deviated from the screw hole. A notch is formed to fit a water supply pipe extending from the attachment side end of the main body.

(Function) The tightening nut is screwed onto the protruding end of the mounting bolt, and is prevented from rotating by the water supply pipe that fits into the fitting portion of the nut. By tightening the mounting bolt from the main body side, the tightening nut moves in the tightening direction of the bolt without spinning idly, and is interposed between the mounting side end of the main body and the tightening nut. Hold the counter board.

(Example) An example of the present invention will be described based on the drawings. In the drawings, A indicates a faucet. The main body 1 of the faucet A is provided with 5 single sticks for temperature adjustment and flow rate adjustment, and a rotatable water spout pipe 6.
The single stake 5 has a water supply pipe 4 for hot water and water introduced from the end on the side where the main body is attached.
4 is connected to mix hot water and water at a predetermined ratio, and at the same time, the necessary amount of mixed water is discharged to the water discharge pipe 6.

The faucet main body 1 described above is fixed to a counter plate 7 around the sink by means of a mounting bolt 2 passing through the inside of the main body from the top surface to the bottom surface.

The mounting bolt 2 is inserted into the bolt insertion hole 1 on the top surface of the main body 1.
It consists of a head 2a projecting upward from b, and a threaded part 2b penetrating the inside of the main body and projecting from the mounting side end 1a of the main body. The head 2a has a bolt fitting socket 1
It is formed to have approximately the same diameter as the fitting hole 1b so as to fit into the fitting hole 1b, and a tightening hole 2c for inserting the tightening tool B is provided on the upper surface thereof, and a locking hole 2c is provided on the circumferential surface of the same head. A collar 2d is provided around the periphery so that when the mounting bolt 2 is inserted into the main body 1, it is latched by the insertion opening 1b.

Further, from the bottom of the tightening hole 2c, a flow path 10 leading to an inlet 9 opened at the mixing chamber 8 position in the main body 1 is bored along the center of the bolt 2, so that the mixing from the single lever 5 section is made. Water is led to the water discharge pipe 6 through the inside of the bolt 2, and gaskets 11 are arranged at key points on the circumferential surface of the bolt 2 to prevent water from leaking from the fitting surface of the main body.

The threaded portion 2b at the tip of the mounting bolt 2 mentioned above has a
The tightening nut 3 is screwed into the counter plate 7 through a stop plate 12 fitted to the back side of the mounting hole 7a.

The tightening nut 3 is formed into a disc shape, and has a female threaded hole 3a in its center for screwing the mounting bolt 2, and a water supply extending from the main body mounting side end 1a on the outer periphery. A fitting part 3b for fitting and fixing the tubes 4, 4 is formed by cutting out the fitting part 3b.

To attach the faucet A having the above configuration to the counter plate 7 around the sink, first insert the faucet main body 1 without the faucet pipe 6 installed into the mounting hole 7a of the counter plate 7 via the washer 13. Attach by inserting the mounting bolt 2 from the tip (Fig. 3).
Then, fit the stop plate 12 into the mounting hole 7a of the counter plate 7 from the back side, screw the tightening nut 3 onto the tip of the mounting bolt 2 by 2 to 3 pitches via the washer 13, and tighten the end of the main body mounting side. Water supply pipes 4, 4 extending parallel to the mounting bolt 2 from the portion 1a are fitted into the fitting portion of the tightening nut 3. By this,
The tightening nut 3 cannot rotate relative to the mounting bolt 2.

Thereafter, the special tightening tool B is inserted into the tightening hole 2c of the head 2a of the bolt 1 protruding from the insertion opening 1b in the upper part of the main body 1, and the mounting bolt 2 is rotated in the tightening direction. Thus, the tightening nut 3 in the above-described state moves upward along the rotating mounting bolt 2 and clamps the counter plate 7 between the main body mounting side end 1a and the stop plate 12. As a result, the faucet main body 1 is securely fixed to the counter plate 7.

Next, the water discharge pipe 6 is fitted onto the head 2a of the mounting bolt 2, and the retaining ring 14 is engaged with the fitting portion to prevent the water discharge pipe 6 from coming off.

In addition, in the above-mentioned embodiment, the mounting bolt 2
Although the inside of the bolt 2 was used as a part of the flow path to the water discharge pipe 6, it is of course optional to use the bolt 2 merely for attachment.

(Effects) In the faucet of the present invention, a mounting bolt is passed through the faucet body and protrudes from the mounting end of the faucet body, and a tightening nut is screwed onto the protruding end.
The nut has a notch formed on the outer periphery that is offset from the screw hole to fit the water supply pipe extending from the installation end of the main body, so that the faucet main body can be attached to the counter board. After installing it on the counter, screw the tightening nut onto the mounting bolt protruding from the back of the counter (2~
3 pitches) and fitting the water supply pipe extending from the installation end of the main body into the fitting part of the nut, the tightening operation of the tightening nut can be performed using the bolt head protruding from the top of the main body. This can be done by tightening. Therefore, the work of tightening the tightening nut, which was conventionally done on the back of the counter board where there were many obstacles, can be easily done on the top of the main body where there are no obstacles, reducing the time required to install the faucet. It can be significantly shortened.
