Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a novel nut anti-loosening structure comprises a bolt 1, a stainless steel wire thread sleeve 2, a main nut 3 and a locking nut 4, wherein the stainless steel wire thread sleeve 2 is in threaded connection with the outer wall of the bolt 1, the main nut 3 is in threaded connection with the left side of the outer wall of the stainless steel wire thread sleeve 2, the locking nut 4 is in threaded connection with the right side of the outer wall of the stainless steel wire thread sleeve 2, a circle of hook groove 5 is arranged at the right part of the inner side of the main nut 3, a circle of hook block 6 is arranged on the outer wall of the left side of the locking nut 4, at least six positioning grooves 7 are uniformly formed in the outer wall of the hook block 6 in an annular shape, at least six slideways 8 are uniformly formed in the right side of the outer wall of the main nut 3 in an annular shape, the slideways 8 are communicated with the hook grooves 5, positioning pins 9 are arranged between the adjacent slideways 8 and the positioning grooves 7 in an alternating mode, the head ends, 6 left ends of hook piece extend to 5 inside with hook groove 5 joints, the quantity and the distribution of constant head tank 7 with the quantity and the distribution one-to-one of slide 8, reset spring 10 head and the tail both ends respectively with the location slightly 9 with main nut 3 contacts, passes the fixed orifices of equipment with bolt 1 after, changes over to bolt 1 outside with stainless steel wire swivel nut 2 earlier, rotates to hugging closely equipment fastening after 2 when stainless steel wire swivel nuts 2, changes over to 2 outsides of stainless steel wire swivel nut to hugging closely equipment fastening again with main nut 3 and lock nut 4 simultaneously.
