Description

Technical Field

[0001] The present application relates to a lock body, and in particular to an anti-rotation lock body and an automatic pipeline winder. Background Art

[0002] The automatic pipeline winder is a structure used to automatically wind up the pipeline (including the pipe body or the wire) to store the pipeline. The commonly used automatic pipeline winder mainly includes a mandrel, a wheel rotatably mounted on the mandrel, a spring arranged between the mandrel and the wheel, etc. The pipeline is wound on the wheel. When the pipeline is pulled out, the pulled out pipeline drives the wheel to rotate around the mandrel, thereby driving the spring to continuously compress and accumulate potential energy; when the pulled out pipeline needs to be wound and stored, the compressed spring releases the potential energy to drive the wheel to rotate, so that the pipeline is wound on the wheel again.

[0003] Among them, an arbitrary locking structure will also be designed on the automatic pipeline winder. Its purpose is to help users more conveniently realize the free pipe output, arbitrary anti-rotation locking and automatic pipe winding of the automatic pipeline winder when using the automatic pipeline winder. The most commonly used arbitrary locking structure is the best use structure with a track group and a locking rod slidably installed in the track group. When the locking rod slides or stops at various positions in the track group, the pipe output rotation, arbitrary anti-rotation locking and pipe winding rotation of the wheel assembly can be realized in turn.

[0004] The above-mentioned push rod is acted upon by the elastic force of the elastic plate so that the push rod always slides in close contact with the track group. However, when the push rod slides inside the track group, the reaction force of the track group on the push rod causes the elastic plate to bend and deform under force. When the elastic plate is in a bent state for a long time, the elastic plate is prone to plastic deformation, resulting in a decrease in its elastic performance, poor structural reliability, and the problem of the pipeline being unable to rewind.
