Referring to Fig. 1, the bolt assembly anti-loose method that one embodiment of the invention proposes, including step S101~S104.

S101 opens up groove in the threaded portion of bolt；

Wherein, as shown in Fig. 2, opening up groove 12 in the threaded portion of bolt 11 111, the quantity of the groove 12 can be 1 It is a or multiple.

Specifically, when the quantity of the groove 12 is at least two, it is preferred that the groove 12 is in the bolt 11 Threaded portion 111 is uniformly distributed.

Wherein, the bore for implementing groove 12 cannot be excessive or too small, the excessive integral strength that will affect bolt 11, too small meeting Lead to anaerobic adhesive insufficient infusion, and inconvenient operation, it is preferred that the bore of the groove 12 is the 11 embryo diameter of bolt 15%-20%.

S102, injecting original state in the trench is solid anaerobic adhesive；

Wherein, as shown in figure 3, injecting original state in groove 12 is solid anaerobic adhesive 13.

The original state of anaerobic adhesive at normal temperature is solid-state, can be converted to liquid by solid-state after anaerobic adhesive is heated.It is preferred that , anaerobic adhesive is solid-state at 18~26 DEG C, is liquid at 30~80 DEG C.When it is implemented, anaerobic adhesive can be using happy safe The related glue of model is realized.
