Description

[Detailed description of the invention] This invention has the strength to allow easy installation even under conditions where the faucet cannot be rotated due to obstructions from other objects, such as bathtubs, when installing a faucet to an existing water pipe. The purpose of the present invention is to provide a rotary socket for a faucet that is also excellent in terms of performance.

Generally, when the connecting end of a water pipe installed inside a concrete wall or the like is buried beneath the wall surface, the faucet is attached via a faucet socket.

However, as shown in Fig. 1, conventional faucet sockets have a cylindrical shape with a through hole 3' formed in a hexagonal or other different diameter cross section in order to fit a rotary operating tool such as a hexagonal wrench. Member 1'
A male threaded portion 2' is formed at one end to be screwed into a female threaded portion a' formed at the end of the existing water pipe A', and the other end is threaded into a male threaded portion of a water faucet (not shown). Since the structure had a female threaded part 8' that fits, when installing the faucet,
The faucet side had to be rotated and screwed into the female threaded portion 8' of the socket, and it was therefore necessary to secure a large working space around the socket in which the faucet could be rotated.

The present invention has developed a rotary socket for a faucet that is superior in operability and strength and can overcome these conventional drawbacks.

An embodiment of the present invention will be described based on the drawings. Fig. 2 is an exploded perspective view showing an example of a rotary socket for a faucet according to the invention, and Fig. 3 is a cross-sectional plan view showing its usage state.

In the figure, reference numeral 1 denotes a male threaded part 2 that screws into a female threaded part a formed at the end of an existing water pipe A, and a cross-section with a different diameter (see the drawing Although the shape shown above is hexagonal, it may be any other polygonal shape or may be oval.

) is a metal cylindrical member having a through hole 3, and the male threaded portion 2 is formed into a tapered shape so as to prevent loosening of the threaded engagement with the female threaded portion a.

Reference numeral 4 denotes a metal cap nut-shaped member that rotatably engages with the cylindrical member 1, and the retaining portions of both members 1 and 4 are conical with the same slope so that they are in surface contact with each other. It is formed on tapered surfaces S, , S,.

5 is a rubber gasket, B is a faucet, and 6 is a male thread formed at the connecting end of the faucet B.

7 is an adjuster used when the diameters of the male threaded portion 6 and the female threaded portion 8 of the cap nut-shaped member 4 do not match and it is not possible to directly screw them together; several types of adjusters with different inner diameters are prepared in advance. has been done.

(Incidentally, if the diameters of 6 and 8 match, the adjuster 7 is not necessary.

) C is a concrete wall.

According to the above configuration, with the cap nut member 4 rotatably engaged with the cylindrical member 1, a rotary operating tool such as a hex wrench is fitted into the through hole 3, and the cylindrical member 1 is connected to the existing water supply pipe. After screwing the adjuster 7 into the female thread part a of the pipe A, as shown in FIG. The faucet B is attached to the existing water pipe A by screwing it onto the water pipe A.

In this case, since the cap nut-shaped member 4 is rotatably engaged with the cylindrical member 1, simply rotating the cap nut-shaped member 4 in one direction connects the female screw portion 8 of the cap nut-shaped member 4 with the adjuster. 7 can be screwed together with the external threaded part 9 of faucet B.
No need to rotate.

Moreover, the engaging portions of both members 1 and 4 have a conical tapered surface S.
1. S4, these tapered surfaces S1. S
As a result, the self-aligning function of the cap nut-shaped member 4 is suppressed, and as a result, twisting of the female threaded portion 8 and the male threaded portion 9 is prevented, and the side threaded portions 8 and 9 can be easily connected. Moreover, it can be screwed into the cylindrical member 1 without any looseness.

Further, since the engaging portion between the cylindrical member 1 and the cap nut-like member 4 is in surface contact with each other by the tapered surfaces S, S4, local wear and deformation of the retaining portion are prevented, and the engagement Since the force generated in the retaining part acts in the radial direction on both members 1 and 4, which have a closed loop cross section, the retaining part does not deform and is extremely robust.

That is, for example, if a flange part perpendicular to the axis is provided at the outer end of a cylindrical member, and a cap nut-shaped member is engaged with this flange part, a flange part that is generated at the engaging part due to screw fitting. The force in the axial direction is resisted only by the bending strength of the flange portion, which tends to deform, but in the above structure, the force is resisted by the strength of the entire cylindrical member 1.
There is no risk of deformation.

The present invention has the above-mentioned configuration, and the faucet can be attached by rotating the nut-shaped member, so there is no need to rotate the faucet side, and there is no need to prevent other objects such as the bathtub from getting in the way. Even under conditions where rotation is not possible, the faucet can be easily attached to an existing water pipe.

In particular, since the cap nut-shaped member and the cylindrical member engage with each other at their conical tapered surfaces, the self-aligning function of the tapered surfaces is exhibited, and the connection between the faucet side and the cap nut-shaped member is achieved. Screw fitting can be easily done without twisting, there is no looseness between the cylindrical member and the nut-shaped member, and there is no local wear or deformation at the engaging portion of both members. , very robust.
