Description

Technical Field

[0001] The utility model belongs to the technical field of threaded sleeves, and in particular relates to a connecting piece threaded sleeve and a connecting mechanism. Background Art

[0002] Common connectors are usually fixed with bolts. Sometimes, in order to enhance the connection strength, improve wear resistance as a consumable, or when the load increases but the diameter and number of bolts cannot be increased, the protective thread will be fixed with a wire screw sleeve. This often has the following disadvantages: 1) The connector is in harsh working conditions or improperly stressed. It is very easy for the thread to slip or the bolt head to break during dismantling. It may be necessary to drill out the bolt to repair the thread or even cause the entire connector to be scrapped, seriously reducing the utilization rate and stability of the equipment. 2) There is a risk that the wire screw sleeve will be easily damaged and carried out. If the bolt breaks inside, it still cannot be easily removed. The removal of the wire screw sleeve requires special tools, which requires high skills of the operator. 3) The wire screw sleeve itself has limited loosening and release performance.
