Embodiment

[0016] Embodiment: A method for preventing locking bolts from loosening according to the present invention is improved on the basis of the existing bolt and nut connection. a keyway, and insert a key block into each keyway, the key block can be made of nylon material or a metal material whose hardness is less than that of the nut material; The thread teeth on the key block are extruded and deformed, and the thread that is tightly matched with the nut is extruded on the key block, so that the thread of the nut and the extruded thread on the key block are closely matched together to produce Locking force, so as to achieve the purpose of preventing the locking bolt from loosening.

[0017] A locking bolt assembly of the present invention constructed according to the above method is: the structural schematic diagram of the locking bolt assembly is as follows figure 1 As shown, including the existing bolt 1, at least one keyway 3 is provided on the threaded section 2 of the bolt 1...

Abstract

The invention discloses a method for preventing a lock bolt from loosening and a lock bolt assembly. According to the invention, at least one key slot is made on the thread section of a bolt, and a key block is inserted into the key slot, then the bolt is screwed into a nut, thread teeth on the nut are used for extruding the key block to be deformed, a thread in closely matched with the nut is extruded on the key block, and then the thread of the nut can be tightly matched with the thread extruded on the key block to generate a locking force, so as to achieve the aim of preventing the lock bolt from loosening. The method for preventing the lock bolt from loosening and the lock bolt assembly not only have the advantages of being reliable in self-locking, good in strength and light in weight, but also has the advantages of being low in requirements on heat treatment, easy to product, low in production cost, convenient to use and the like.

Description

technical field [0001] The invention relates to a method for preventing locking bolts from loosening and a locking bolt assembly, belonging to the technical field of self-locking bolts. Background technique [0002] Ordinary bolts generally do not have a self-locking function, and they can basically meet the requirements for use in general occasions. However, when used in some occasions with high vibration, the bolts will loosen due to the vibration. Therefore, in some special occasions, a shockproof locking bolt must be used. There are many locking bolts on the market at present, and the structures are also different. However, these locking bolts generally have the problems of troublesome manufacture and high production cost, and some of them have the problem of poor strength, so their use effect is not ideal. Contents of the invention [0003] The object of the present invention is to provide a method for preventing locking bolts from loosening and a locking bolt asse...
