Description

Technical Field

[0001] The utility model relates to the technical field of closed pins, in particular to a closed pin component that is easy to use and prevents a nut from separating. Background Art

[0002] A closing pin is a device used to limit the position of a nut. During the operation of the equipment, vibrations will be generated, which will cause the nut to separate from the bolt. The nut is fixed by a closing pin. The closing pin is cylindrical, with a larger diameter at one end to prevent the closing pin from falling due to vibrations generated during the operation of the equipment. The closing pin can ensure stable operation of the equipment.

[0003] Most of the existing closed pins are of a single length. One model of closed pin can only adapt to the corresponding kit, and the length cannot be adjusted. It is not suitable for most nuts. In addition, during the rotation of the equipment, the end of the closed pin with a smaller diameter is likely to fall off, and the nut cannot be stably fixed. In response to this technical problem, the present application proposes an easy-to-use anti-nut detachment closed pin assembly. Utility Model Content
