Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, 2 and 3, the anti-disassembly nut comprises a nut base body 1 and a hexagonal rotating body 2, an internal thread through hole is formed in the nut base body 1, limiting steps 3 are arranged at two ends of the nut base body 1, ratchet parts 4 are arranged on the outer peripheral wall of the nut base body 1, the hexagonal rotating body 2 is sleeved on the nut base body 1, a plurality of mounting grooves 5 are uniformly formed in the inner peripheral wall of the hexagonal rotating body 2, anti-disassembly assemblies are mounted in the plurality of mounting grooves 5, each anti-disassembly assembly comprises a pawl 6 and an elastic piece 7, the pawl 6 and the elastic pieces are meshed with the ratchet parts, and the elastic pieces 7 are arranged between the bottoms of the mounting grooves 5 and the pawl 6.

In a detailed description, the hexagonal rotary body 2 and the nut base body 1 are connected in a riveting mode, a gap is formed between the inner peripheral wall of the hexagonal rotary body 2 and the outer peripheral wall of the nut base body 1, the hexagonal rotary body 2 can rotate clockwise along the central axis through the gap, the nut base body 1 is kept still, the one-way anti-disassembly effect is achieved, and the stability and the inseparable effect are enhanced through the connection in a riveting mode.

Principle of operation

Through the arrangement of the pawls 6 on the inner peripheral wall of the hexagonal rotary body 2, which are matched with the ratchet parts 4 on the outer peripheral wall of the nut base body 1, when the hexagonal rotary body 2 is screwed up in a counterclockwise rotating manner, the pawls 6 can drive the nut base body 1 with the ratchet parts 4 to be screwed up in a rotating manner; when the hexagonal rotary body 2 rotates clockwise, the pawl 6 moves upwards along the back of the ratchet part 4 to separate the ratchet part 4, so that the nut base body 1 is fixed, and the hexagonal rotary body 2 rotates clockwise, thereby achieving the effect of unidirectional anti-disassembly.
