Description

[Detailed Description of the Invention] The present invention relates to an improvement in a faucet in which the spindle is installed by threading a spindle support member that is screwed into a cylindrical portion provided in the main body.

Conventionally, various structures have been known for this type of faucet.
For example, there is a method disclosed in Japanese Utility Model Application Publication No. 54-12010 shown in FIG.

To explain the thing in Fig. 2, a spindle support member is screwed onto the inner peripheral surface of the cylindrical portion 4 of the faucet body a, and the spindle C is screwed through the inner peripheral surface of the spindle support member. It extends into the stopper body a so that it can move forward and backward, and as the spindle C moves back and forth, a valve body f provided at the tip of the spindle C approaches and separates from the valve seat 3 to open and close the valve portion.

The spindle support member is formed into an enlarged opening 12 via a stepped portion 11 at the front of the threaded part with the spindle C, and the spindle C is formed into an enlarged opening 12 in front of the threaded part with the spindle support member. A large diameter portion 17 having approximately the same diameter as the inner diameter of the enlarged opening 12 of the spindle support member is formed.

Therefore, when the spindle C is moved backward and the valve part is opened to the maximum extent, the upper surface of the large diameter part 17 of the spindle C comes into contact with the lower surface of the stepped part 11 of the enlarged opening 12 of the spindle support member. The spindle C and the spindle support member S rotate together due to the frictional force, and the spindle support member S falls off from the faucet body a.

The present invention solves the above problem and opens the valve part to the maximum extent (thereby, even if the rotational force of the spindle is applied to the spindle support member screwed onto the faucet body, the spindle support member is lower than the faucet body). The purpose is to prevent it from falling off.

The technical means taken by the present invention to achieve the above object is to provide a male screw part on the outer peripheral surface of the cylindrical part of the faucet body, and to screw the presser part into the male thread part. The flange of the spindle support member is clamped between the lower surface of the flange and the upper edge surface of the opening of the cylindrical portion, and the spindle support member is fixed to the faucet body, so that rotation of the spindle is applied to the spindle support member. This is to prevent the spindle support member from rotating even when the spindle support member is rotated.

Since the present invention has the above configuration, it has the following advantages.

■ Even if the upper surface of the large diameter part of the spindle comes into contact with the soil wall surface of the enlarged opening of the spindle support member due to spindle operation, the first flange of the spindle support member will The spindle supporting member rotates with respect to the faucet body due to the rotation of the spindle. There's nothing to do.

Therefore, the spindle support member does not come off from the faucet body due to the operation of the spindle.

■ If adhesive is applied to the threaded part between the spindle support member and the faucet body to prevent the spindle support member from falling off, it will not be possible to disassemble the two, making it difficult to repair the valve part.
According to the present invention, even if the valve part breaks down, the holding tool can be unscrewed and removed from the main body, making it easy to repair the valve part.

■ The structure is extremely simple and can be manufactured at low cost.
