Description

Technical Field

[0001] The utility model relates to the technical field of pulley brackets, in particular to a pulley bracket for preventing from slipping out of the groove. Background Technique

[0002] A pulley is a small wheel with a groove on its periphery that can rotate around an axis. A simple machine that can rotate around a central axis and is composed of a disc with a groove that can rotate around the central axis and a flexible cable (rope, tape, steel cable, chain, etc.) that crosses the disc is called a pulley.

[0003] Currently, the pulley brackets for preventing from slipping out of the groove in the prior art are usually pulley brackets for restricting flexible cables. When in use, since most pulley installation positions are at high places and are installed by bolts, the stability is poor and the installation efficiency is low. There is a problem that it is not convenient to install the pulley bracket. And when in use, the flexible cables matched with the pulley are different, and the diameter sizes are also different accordingly, while the anti-slip-out-of-groove structure cannot be adjusted. Therefore, the anti-slip-out-of-groove effect is poor, and there is a problem that the position of the anti-slip-out-of-groove structure cannot be adjusted. Content of the Utility Model
