Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a faucet having a structure in which a base of a water discharging device is rotatably connected to a columnar faucet main body that stands upright on a mounting surface.

[Conventional technology]

Conventionally, a column-shaped faucet body was fixed to the mounting surface, and the base of the faucet, which had a faucet attached to the tip, was rotatably connected to the body of the faucet body. There is one described in Publication No. 35949.

As shown in Fig. 3, this is a single-lever type hand spray faucet, with a rotating supporting part 52 that allows a hand spray 51 to be inserted into and taken out from the body of the faucet main body 50, which has a built-in valve element on the upper side. Mixed water at a comfortable temperature is discharged from the hand sprayer 51 by opening and closing a flow path of a valve element which is freely connected and linked to the operation of a lever handle 53 disposed at the upper part.

The support part 52 forms a holder part 55 for storing and supporting the base end of the hand spray 51 on the side of a cylindrical part 54 into which the body of the faucet main body 50 is fitted, and allows the hand spray 51 to be taken out in any direction. It has a configuration in which it is connected to the faucet main body 50 so that it can be changed.

[Problem that the invention attempts to solve]

The faucet main body 50 is installed and fixed on the mounting surface 56 by inserting the cylindrical portion 57 provided at the bottom of the faucet main body 50 into the mounting opening 58 and screwing the fixing nut 59 onto the male thread of the cylindrical portion 57. This is done by

In this case, keep the faucet body 50 stationary and tighten the nut 59.
The faucet body 50 must be rotated and tightened using a tool such as a spanner, but in order to fix the holder part 55 on the mounting surface 56 so that it faces the front, the faucet body 50 must be tightened with the nut 59.
It is necessary to hold it so that it does not rotate due to tightening.

However, since the faucet body 50 does not have any tool hooking part and the support part 52 rotates relative to the faucet body 50, in order to hold the faucet body 50, care must be taken to avoid damaging the upper part of the faucet body 50. It is necessary to prevent co-rotation by holding it down.

In this way, with the conventional faucet structure, tools cannot be hung on the faucet body 50, so the nut 59
There is a problem in that co-rotation due to tightening cannot be completely prevented, and it is difficult to fix the faucet main body 50 onto the mounting surface 56.

The purpose of the present invention is to easily install and fix the faucet body in a faucet in which the base end of the water discharging device is rotatably connected to the faucet body, which is erected through the installation opening. It is.

[Means and actions for solving problems]

In this invention, a sleeve is provided at the bottom of the faucet main body through which the installation port is inserted, a supply pipe is inserted through the sleeve to the valve element in the main body, and a male screw formed in the sleeve is connected to the mounting surface. In a faucet in which a fixing nut is screwed from below, and the base end of the water spout is formed into a cylindrical shape and is inserted into the faucet so as to be rotatable, a ring that supports the lower surface of the base of the water spout is fitted to the bottom of the main body. When inserted, the ring is fixed with a fixing screw whose head is exposed to the outside, and the head of the fixing screw is provided with a recess for hanging a tool, and when the tool is engaged with the recess, the main body is tightened. This is to prevent the parts from rotating together.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 is a longitudinal sectional view of a faucet according to the present invention, and FIG. 2 is a partially cutaway front view.

In the figure, 1 is a water supply at the bottom, a water supply connecting hot water pipes 2 and 3, and a connecting tube for communicating the flow path from the hot water source to the water outlet side, and 4 is connected to the lower end of the connecting tube 1 for installation. A sleeve 6 is screwed and connected to the upper part of the connecting tube 1 and has a valve inside. A valve cylinder equipped with elements, and 7 are a water discharging tool which integrally connects a water discharging pipe 8, has a cylindrical base end, and is rotatably inserted into the circumferential surface of the connecting pipe 1,
These elements constitute the main body C of the faucet.

In the above-described main body C structure, the valve cylinder 6 is provided with a cartridge type case 10 containing a valve element, and the operating rod 12a is operated by operating the fixed valve plate 11 and lever handle 12 stationary within the case 10.
A movable valve plate 13 is arranged to slide on the surface of the fixed valve plate 11 via the movable valve plate 13.

The fixed valve plate 11 has a water inflow hole 14 communicating with the water supply and hot water supply pipes 2 and 3, a hot water inflow hole 15, and a mixed water outflow hole 16 communicating with the cavity 1a formed in the connecting tube 1.
has been established. In addition, the movable valve plate 13 always has a first valve hole 17 communicating with the mixed water outflow hole 16 of the fixed valve plate 11, a water inflow hole 14, and a hot water inflow hole 15, which can be aligned or misaligned by operating the lever handle 12. A second valve hole 18 is provided to make the flow path opening variable.
A flow path 19 is formed in the movable valve plate 13 through which water and hot water flow, and the water and hot water supply pipes 2 and 3 are communicated with the cavity 1a of the connecting tube 1.

Note that 20 is a synthetic resin cover attached to the valve cylinder 6.

As described above, the connecting tube 1 has a cavity 1a that communicates with the inside of the case 10, an opening 21 that communicates with the water discharge pipe 8, and a female threaded hole 22 in the lower part of the back side. There is.

Reference numeral 23 denotes a cylindrical ring that fits around the circumferential surface of the connecting tube 1, and the lower end surface of the water discharging tool 7 slides on and supports the upper end surface of the ring. The fixing screw 25 is then screwed into the female screw hole 22. A recess 26 is formed in the head of the fixing screw 25 to hold a tool, and also to restrain displacement of the ring 23 in the circumferential direction and fix the ring 23.

In the above configuration, in order to install the main body C, which integrates the cover 20, the lever handle 12, and the ring 23, on the mounting surface A, insert the sleeve 4 into the mounting opening B as shown in FIG.
A washer 31 is attached, and the nut 5 is screwed onto the male thread 4a of this sleeve 4 and tightened. At this time, the recess 2 of the fixing screw 25 arranged on the ring 23
A tool such as a screwdriver is inserted into 6 to hold the entire main body C so that it does not rotate.

As described above, the main body C can be fixed to the mounting surface A by using the tool to prevent the main body C from rotating together with the tightening rotation of the nut 5.

Furthermore, if the ring 23 that slides and supports the cylindrical lower surface of the base end of the water discharging tool 7 is made of synthetic resin, the water discharging tool 7 can smoothly rotate and the direction of the water discharging pipe 8 can be changed with a light touch. .

[Effect of idea]

This invention has a tool hook on the main body of the faucet, so even if the water discharging device is rotatably connected to the main body, it can prevent co-rotation due to tightening and rotation of the nut, and it can be easily installed and fixed on the mounting surface. It has the effect of being able to do it.
