Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a leg side mounting structure of a conduit connecting a faucet body and a leg.

[Prior Art] There are one and two operation handles for hot and cold water mixing faucets, one is called a single lever type, and two are called a two-handle type. There is.
In addition, there are two types of hot and cold water mixing faucets, in which the legs connected to the supply source of hot water and water are gathered in one cylinder, and the one is a two-hole type. . The present invention relates to a single-lever and two-hole hot and cold water mixing faucet.

A conventional single-lever two-hole hot and cold water mixing faucet is shown in a partial sectional front view of FIG. 6 and a partial sectional side view of FIG. As shown in the same figure, a conventional hot and cold water mixing faucet 1 of this type has a faucet body with a cylindrical pin member 5a, 5b at the center of a base outer shell 4 composed of a bottom plate 2 and a cover 3. 6 are erected. The bottom plate 2 and the cover 3 are connected by a screw member (not shown). The faucet body 6 is fixed to the bottom plate 2 by penetrating the cylindrical pin members 5a, 5b from the lower surface side of the bottom plate 2 and screwing the screw members 7a, 7b to the faucet body 6.

A water spout portion 9 having a water spout 8 is rotatably fitted on the outer peripheral surface of the faucet body 6 on the lower side. On the other hand, a cap 10 is externally mounted on the outer peripheral surface of the faucet body 6 on the upper side by screwing. A valve mechanism 13 composed of two disc valve bodies, a fixed disc 11 and a movable disc 12, is arranged on the upper surface side of the faucet body 6. Cap 10
By operating the movable disk 12 with a single lever 14 that penetrates the head of the
It is possible to control Thereby, the temperature of the hot water discharged from the water discharge port 8 can be adjusted to a desired value.

Thus, on both ends of the bottom plate 2, there are attached legs 15 and 16 which serve as both the hot and cold water mixing faucet 1 and the hot water and water inflow passages. The legs 15 and 16 are connected to hot water and water inlets 19 and 20 of the faucet body 6 via conduits 17 and 18 arranged in the base outer shell body 4. Said conduits 17 and 18
Has bent portions 17a, 17b and 18a, 18b bent in an L shape, and both ends of the bent portions 17a, 17b and 18a, 18b are the faucet body 6 and the leg portions 15 and 16, respectively.
Are connected by brazing. The leg portions 15 and 16 are configured such that the pin member 21 attached to the leg portions 15 and 16 fits into the pin hole of the bottom plate 2 to prevent the leg portions 15 and 16 from rotating. This is because, without this anti-rotation structure, when the nuts 23 are screwed and fastened when the leg portions 15 and 16 are attached to the wash counter 22 etc., the leg portions 15 and 16 and the conduits 17 and 18 become the nut 23. This is because there is a problem that the pipes 17 and 18 made of bronze are twisted together by the tightening force and twisted. In addition, as a rotation stopping mechanism between the leg portions 15 and 16 and the bottom plate 2, there is another method in which a polygonal portion is formed at a fitting portion between the both.

By the way, in FIGS. 6 and 7, 24 is a rubber packing arranged on the lower surface side of the bottom plate 2, 25 is a hot water outlet formed in the faucet body 6, and 26 is a mixing chamber.

[Problems to be solved by the device]

However, the conventional legs 15 and 16 and the conduits 17 and 18
The detent mechanism between and has a drawback that the upright postures of the legs 15 and 16 are easily inclined. That is, in both the case of using the pin member 21 and the case of forming the polygonal fitting portion, when the leg portions 15 and 16 are attached, the whirl-stop mechanism shown in FIG. When a moment in the direction of tilting the upright posture as shown by the arrow in FIG. 7 is applied, the bent portions 17b and 18b of the conduits 17 and 18 are easily bent and the posture thereof is collapsed. In particular,
In the rotation stop mechanism using the pin member 21, such a leg portion is
When the postures of 15 and 16 collapse, the pin member 21 and the pin hole of the bottom plate 2 cannot be fitted to each other, resulting in defective mounting.

Also, the connection between the legs 15 and 16 and the conduits 17 and 18 must be made by brazing. This brazing work is
This was extremely troublesome because the conduits 17 and 18 had to be left inserted into the legs 15 and 16 in the narrow area where b and 18b existed.

Furthermore, the legs 15 and 16 are, as shown in FIG.
It is formed of a flange portion 27 and a cylindrical body portion 28. And
In the conventional manufacturing of the leg portions 15 and 16, a tubular material having the size of the flange portion 27 is carved out. As a result, chips are generated by the amount of the dimensional difference between the flange portion 27 and the cylindrical body portion 28, and there is a drawback in that the amount of wasted material increases. Since such legs 15 and 16 are usually made of expensive bronze, the problem of a large amount of chips was extremely important.

[Means for Solving the Problems]

The present invention has been made by improving and removing the above problem in view of the above-mentioned conventional problems, and it is possible to form a connection between a conduit and a leg and a detent mechanism with a simple structure, and yet to prevent the flange of the leg from being formed. The purpose is to provide a mounting structure that can be omitted.

The means adopted by the present invention to solve the above-mentioned problems are a faucet body provided with a valve mechanism for controlling the flow rates of hot water and water, and a leg portion connected to a hot water and water supply source. In a hot and cold water mixing faucet configured to be connected by a conduit arranged in a base outer shell formed by a bottom plate and a cover, at a bent portion of the conduit located at a connecting portion with the leg portion, A hot and cold water characterized in that a divided holder capable of holding a bent portion is externally fitted and attached, the holder is screwed to the leg portion, and a rotation preventing mechanism for the holder is provided in a base outer shell. It is a leg mounting structure of a mixed faucet.
