Anti-shake fixture for tail end of walker parts

Abstract

The invention discloses an anti-sway fixture for the tail end of a walker part, which includes a fixture, a flexible part, a sleeve and an end cover. One end of the flexible part is connected with the clamp, and the other end of the flexible part is connected with the sleeve, and the sleeve can be placed on the pipe. On, the end cap is provided with internal threads. The pipe fittings are inserted into the casing and then clamped by the fixture, and the end cap is screwed to the end of the casing and pressed against the end of the pipe inside the casing. When the end cover is rotated, the end cover is displaced axially relative to the sleeve, and the sleeve tightens the flexible part. The tail end of the pipe is limited by the sleeve and the end cover. When the operator cuts, chamfers, grinds or otherwise cuts the front end of the pipe During processing operation, the tail end of the pipe will not swing, and the pipe is positioned stably.

Description

technical field [0001] The invention relates to a rehabilitation appliance and a living aid, in particular to a walking aid. Background technique [0002] A walker, also known as an assisted rehabilitation walker, has an overall structure similar to a wheelchair, including a frame, wheels installed at the bottom of the frame, and a pair of handles installed at the top and back of the frame. Among them, the vehicle frame is assembled from several pipe fittings, and the pipe fittings need to be cut, chamfered and polished before assembly. [0003] According to the prior art, pipe fittings are cut, chamfered, and polished, and fixtures are required to clamp the pipe fittings. If the pipe fittings are long, a thimble needs to be pushed against the tail end of the pipe fittings to prevent the pipe fittings from shaking. The thimble needs a corresponding guide rail for its displacement. The guide rail and the fixture should be an integral structure, or the guide rail and the fixt...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned cooperation of the clamp and the thimble for fixing the pipe fittings has the following problems: first, the clamp and the thimble, and the supporting guide rail or base occupy a large space; The cost is high. During use, the accuracy deviation of the guide rail or thimble exceeds the allowable value, that is, it cannot be used normally; third, the thimble acts on the tail end of the pipe, and the pipe part between the tail end of the pipe and the fixture is easy to bend
