Problems solved by technology

[0002] With the development of industry, a large number of screws are used in industrial production. There are many kinds of screw structures. After these screws are produced and stored in the space for a long time, many screws will oxidize, which makes the screws unusable. It will eventually lead to the scrapping of the screw. At the same time, the friction generated during the usual transportation will also wear the thread on the surface of the screw, which is very troublesome. In addition, it is used in some vibration equipment. After combining the screw with the screw sleeve, Due to long-term vibration, it is easy to cause looseness between the screw and the screw sleeve, which will cause the screw to slip off and cause equipment failure

Abstract

The invention relates to a locking type screw socket with pre-stress. The locking type screw socket with pre-stress comprises a sleeve and inner threads formed in the inner wall of the sleeve, wherein an anti-rusting layer coats on the outer surface of the sleeve, and is 1-2 mm in thickness; a glue injecting hole is formed in the side wall of the sleeve; an S-shaped slot communicating with the glue injecting hole is formed in the inner wall of the sleeve. The locking type screw socket with pre-stress disclosed by the invention injects an adhesive during use, so that the connection between the screw and the screw socket is relatively firm, and a slip phenomenon is avoided.

Description

technical field [0001] The invention relates to the field of connecting parts, in particular to a locking screw sleeve with prestress. Background technique [0002] With the development of industry, a large number of screws are used in industrial production. There are many kinds of screw structures. After these screws are produced and stored in the space for a long time, many screws will oxidize, which makes the screws unusable. It will eventually lead to the scrapping of the screw. At the same time, the friction generated during the usual transportation will also wear the thread on the surface of the screw, which is very troublesome. In addition, it is used in some vibration equipment. After combining the screw with the screw sleeve, Due to long-term vibration, it is easy to cause looseness between the screw and the screw sleeve, which will cause the screw to slip off and cause equipment failure. Contents of the invention [0003] The technical problem to be solved by th...
