JP5387970B2 - Release wire end of remote-controlled drain plug device - Google Patents

Description

  The present invention relates to an end portion of a release wire of a remote-operated drain plug device, and more particularly to a built-in structure of the end portion.

The both ends or one end of the release wire of the conventional remote-operated drain plug device are composed of a box body to which the outer tube is fixed and a cap body through which the shaft continuing to the inner wire is slidably inserted. Thus, the box body and the cap body are snap-fitted and integrated.
Further, the box body and the cap body are bonded by welding.

However, the case in which the box body and the cap body are integrated by snap-fitting is inconvenient because the box body may come off from the cap body when a load is applied.
In addition, a box body and a cap body that are joined and integrated by welding may be decomposed in the event of a lack of welding. This could cause poor sliding of the shaft.

  Therefore, a male screw is formed on the outer peripheral surface of the box body to which the outer tube is fixed, and a female screw is formed on the inner peripheral surface of the cap body through which the shaft continuing to the inner wire is slidably inserted. These are integrated with each other by screwing.

When inserting into the cap body, an axial groove is formed through which the projection body and the nail body are inserted, and when the box body inserted in the axial direction is twisted, the projection body is twisted around. A horizontal groove that is guided and guided is formed, and an axial rotation prevention groove that prevents the nail body from being twisted back is formed, and the horizontal groove for these protrusions and the nail body is prevented. Cylinder can be secured by fixing to the groove. In which the body and the box body and are integrated.

  The present invention forms a protrusion and a sawtooth unidirectionally rotatable claw member extending in the axial direction on the outer peripheral surface of one cap body or box body, and the inner peripheral surface of the other cylindrical box body or cylindrical cap body. In the axial direction, a groove is formed in the axial direction through which the protrusion and the claw body are inserted, and a lateral groove is formed along which the protrusion follows the twist, and the twisting back of the nail body is prevented. By forming the anti-returning groove, it is possible to easily and easily fix the protrusion and the claw body to the lateral groove and the anti-returning groove by simply inserting and twisting the work. Can do. In addition, it is possible to form a rigid built-in bond that does not easily decompose.

And even if a load is applied without causing a slack as in the case of being integrated by screwing, the screwing is not released due to the loosening and is not disassembled, and does not fall off due to the disassembly.
Further, unlike the case of bonding by welding, the inner wire and the shaft do not slide and the built-in thrust lock mechanism does not operate due to the effects of welding distortion and burrs generated in the welding allowance.
