As an example, a thread locking agent is applied to prevent loosening when the nut is assembled with the thread.
In particular, the thread locking agent is a one-component sealing adhesive prepared by utilizing the oxygen-free radical polymerization inhibition principle, and can be used for bonding and sealing. When the adhesive-coated surface is isolated from air and is catalyzed, it can be polymerized and cured quickly at room temperature. The screw is easy to loosen or fall off under the action of impact vibration, the traditional mechanical locking method is not ideal, and the chemical locking method is cheap and effective. If the screw is assembled after being coated with anaerobic adhesive, a tough plastic adhesive film is formed in a thread gap after solidification, so that the screw is locked without loosening.
As an example, the thickness of the rivet connection pair is determined by the length of the thread.
Specifically, by controlling the length of the screw thread, the adjustable riveting thickness is realized, and the flexible adjustability of the rivet connection pair is improved. Considering the size of the space of the cavity structure, the thread length is not suitable to be longer, and can be set according to actual conditions.
