BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated structure of a water and water mixing faucet, in which a water supply pipe and a hot water supply pipe for pipe communication with a valve portion of a water faucet main body are mounted by penetrating a faucet mounting surface. Things.

[0002]

2. Description of the Related Art A water supply pipe and a hot water supply pipe are pierced through a water faucet mounting surface such as a sink surface or a wash basin deck surface, and the water supply pipe and the hot water supply pipe are mounted on a valve portion of a water faucet body mounted on the mounting surface. A configuration in which the water supply pipe and the hot water supply pipe are covered with a cover and integrated with the faucet main body while communicating with the pipes has been conventionally described in Japanese Utility Model Publication No. 4-30464.

[0003]

However, according to the structure described in the above-mentioned publication, when an external force is applied to the sockets brazed at the ends of the water supply pipe and the hot water supply pipe at the time of transportation or installation of the pipes, the sockets are not provided. There is a possibility that the water supply pipe or the hot water supply pipe may be separated from the mounting plate in the cover, and the water supply pipe or the hot water supply pipe may be bent or the brazed portion may come off to cause water leakage. That is, conventionally, the socket has a structure in which the flange portion is simply sandwiched between the mounting plate and the cover, so that when an inward external force is applied to the socket, the socket separates from the mounting plate, and in this state, the socket is detached. When the nut is tightened to the socket, the socket may rotate around, and stress may concentrate on the brazed portion and breakage may occur.

[0004]

The hot and cold water mixing faucet of the present invention is intended to solve the above-mentioned problem, and a fixing plate is fixed to a lower part of a faucet body containing a mixing valve element by a suitable fixing means. A water supply pipe and a hot water supply pipe communicating with the mixing valve element are arranged on a mounting plate from a lower part of the faucet body, and a socket fixed to the other end of the water supply pipe and the hot water supply pipe is provided at a lower part of the faucet body of the mounting plate. A water / water mixing faucet, which hangs down from the more displaced opening and covers the water supply pipe and the hot water supply pipe by covering the mounting plate with a cover provided with an installation port through which a faucet main body projects upwards, At the upper end, a flange is formed integrally with the upper surface of the mounting plate, and a claw piece integrally provided on the peripheral edge of the opening of the mounting plate is engaged with the upper surface of the flange to thereby form the socket with respect to the mounting plate. It is special that the It is obtained by the.

[0005]

Since the claw is engaged with the upper surface of the flange of the socket, the socket and the mounting plate are integrated so as not to be easily detached by an external force, so that deformation and breakage can be prevented.

Reference numeral 24 denotes a substantially rectangular mounting plate fixed to a lower part of the faucet main body 1, that is, a protruding shaft portion 25 which is formed to hang down from the lower surface of the base cylinder body 2 by screws 26 as fixing means. Reference numeral 24 denotes a steel plate, on which ribs 27 for reinforcement are formed, and through holes 2 on both side edges of the central portion through which screws 26 can be inserted from below.
8 have been established.

At both ends of the mounting plate 24 displaced from the lower part of the faucet main body, openings 33 and 34 are formed through which the sockets 29 and 30 can penetrate and hang down. 35, 36 are hexagonal openings 3 matching the outer diameter of the flanges 31, 32;
7 is formed, and the fixing plates 35 and 36 are attached to the mounting plate 2 by fixing plates having claw pieces 38 formed upright at the inner edge of the opening 37.
The openings 33 and 34 have the same centers on the upper surfaces of both ends of 4 and are integrally fixed by spot welding.

Reference numeral 39 denotes an engagement piece integrally formed on both side edges of the mounting plate 24 so as to be bent upright. The engagement piece 39 has an elongated hole-shaped engagement window 40. 41 is the mounting plate 2
4 is a vibration-retaining piece that extends further outward than both ends.

FIG. 5 shows sockets 29 and 30 with openings 33 and 3 respectively.

It can be fixed without play using

As shown in FIGS. 1 and 2, a packing 48 is laid on the mounting surface 47,
Sockets 29, 3 respectively in the mounting holes 49, 50 opened in
0, and from the lower side of the mounting surface 47, the sockets 29, 3
The installation is set by connecting the sockets 29 and 30 to a water supply source and a hot water supply source, respectively, by fastening the nuts 53 with the packing 51 and the washer 52 interposed therebetween. When tightening the nut 53, the sockets 29, 30
Torque is applied to the nut 53, which can tighten the nut 53 without rotating since the flanges 31 and 32 are non-rotatably fitted in the openings 37.

As shown by phantom lines in FIG. 4, fixing plates 35 'and 36' having claw pieces 38 'bent inside.
If the sockets 29 and 30 are passed through the water supply pipe 7 and the hot water supply pipe 8 before they are joined to the water supply pipe 7 and the hot water supply pipe 8, the fixing plates 35 'and 36' can be spotted on the mounting plate 24 later. The flanges 31 and 32 can be fixed on the mounting plate 24 by welding.

In the above-described embodiment, the fixing plates 35, 36 or the fixing plates 35 ', 36' are fixed to the upper surface of the mounting plate 24, so that the sockets 29, 30 can be set non-rotatably. Even without using a simple fixing plate, for example, as shown in FIG. 6, the claw pieces 3 are formed on the peripheral portions of the openings 33, 34 so as to be positioned upright on the polygonal surfaces of the flanges 31, 32.
The sockets 29 and 30 can also be fixed non-rotatably by forming 8 'and bending the claw piece 38'.

The flanges 31 and 32 are not limited to the hexagons shown in the embodiment but may be other polygons or claw pieces 38 or 3.
A notch may be formed so that 8 'can be engaged. Further, in the above-described embodiment, an example in which a disk-type mixing valve unit is used as the mixing valve element has been described, but a valve body having a cylindrical shape or another form may be used.

[0021]

As described above, in the hot and cold water mixing faucet of the present invention, the socket does not separate from the mounting plate surface even when external force is applied by fixing the faucet body and the socket to the mounting plate.
It can effectively prevent water pipes and hot water pipes from being deformed or their brazed parts peeling off and leaking water, as well as damage to the cover. There are beneficial effects to improve.
