Abstract

The invention relates to an anti-loosing fastener, which comprises a nut body and a screw which are screwed mutually, wherein one end of the screw is provided with external screw threads, and the other end of the screw is provided with a chock plug; the cap body is a regular polygonal prism block with an internal threaded hole in the axial direction; an axial striped hole communicated with the internal threaded hole is formed in the centre area of each of at least two opposite sides in the cap body, and the axial central lines of the two striped holes and the axial line of the cap body are coplanar; a radial perforation which passes through the axial line is formed on one end with the external screw threads of the screw; and an opening pin is arranged in the striped hole on one side, the perforation and the striped hole on the other side to position the cap body on the screw. The two ends, positioned outside the cap body, of the opening pin are sleeved with a gasket respectively. The cap body is a regular hexagonal prism block, and an axial striped hole which is communicated with the through hole with the internal screw threads is positioned in the centre area of each of every two opposite sides in the cap body respectively, and axial centre lines of the opposite every two striped holes and the axial line of the cap body are coplanar. When used, the fastener is not loosed caused by vibration and the like.

Description

technical field [0001] The invention relates to an anti-loosening fastener. Background technique [0002] The existing fastener consisting of bolts and nuts is easy to install, easy to disassemble and widely used. Due to the threaded connection, the nut is easy to loosen. At present, for the anti-loosening of the fasteners, the simple structure of double nuts or spring washers is widely used. Although these structures have a certain anti-loosening effect, there are still the following disadvantages: the fasteners are vibrated more violently. Or when used in places with frequent sports, the phenomenon of nut loosening will still occur, so that its insurance factor is low, accidents are prone to occur, and production and personal safety are endangered. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-loosening fastener, which will not loosen due to vibration and other reasons when the anti-loosening fasten...
