[0002] In mechanics, the typical pulley is a round pulley that can rotate around the central axis, and has a groove on the circumference of the round pulley. The rope is wound in the groove, and when pulling either end of the rope, the friction between the rope and the round pulley will cause the round pulley to rotate around the central axis. The pulley is actually a deformed and rotatable lever. The main functions of the pulley are to pull the load, change the force direction, transmit power, etc. The mechanism composed of multiple pulleys is called "pulley block" or "compound pulley". The mechanical benefit of the pulley block is large, and it can pull a heavy load. The pulley can also be a component of chain transmission or belt transmission, which transmits power from one rotating shaft to another rotating shaft.

[0003] The existing pulley winds the rope in the groove to achieve the corresponding transmission purpose when in use, but has the following defects: (1) when the pulley is in use, the rope is placed in the groove of the pulley for traction, but during the pulling process, the rope is easy to deviate and fall out of the groove of the pulley, which causes the pulley to not work normally. Therefore, we propose a pulley with anti-deviation structure. UTILITY MODEL CONTENT
