Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] as attached figure 1 As shown, a kind of anti-loosening bolt according to the present invention includes a head 1 and a threaded shank 2, and there is a step 3 between the head 1 and the threaded shank 2, and the step 3 can be internally threaded The movable step is provided with a perforation 4 that can communicate with the outside from the inside of the threaded rod part 2 to the outer surface of the step 3; inside the said threaded rod part 2, there are also multiple groups that communicate with the perforated holes 4 and communicate with the said step. The oblique hole 5 extending on the outer surface of the threaded rod part 2; the oblique hole 5 and the through hole 4 are integrally injection molded with the head part 1 and the threaded rod part 2. Wherein the oblique hole 5 is connected with the perforation 4 in a ratch...

Abstract

The invention relates to a lock bolt. The lock bolt comprises a head and a threaded rod part, wherein a step is formed between the head and the threaded rod part, and perforations which can be externally communicated are formed from the interior of the threaded rod part to the outer circular surface of the step; multiple groups of inclined holes which are communicated with the perforations and extend toward the outer circular surface of the threaded rod part are also formed inside the threaded rod part; and the inclined holes, the perforations, the head and the threaded rod part are integrated in an injection moulding manner. The lock bolt provided by the invention can effectively prevent looseness during transportation or in a long-term using process, fastening performance is enhanced, and transportation safety and reliability are enhanced, so that a safety accident can be avoided; meanwhile, the structure is simple and reasonable.

Description

technical field [0001] The invention relates to a bolt, in particular to an anti-loosening bolt, and belongs to the technical field of fasteners. Background technique [0002] Bolts are widely used, and in many occasions a tight fit between the bolt and the nut is required to prevent the bolt from loosening. Such as the bolts on the car, the current common solution to the loosening of the bolts is to add a spring washer between the bolt and the nut to prevent the bolts from loosening. But even this only reduces the possibility of bolt loosening, and does not address the real cause of bolt loosening. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a lock bolt that can not only effectively prevent loosening, but also increase the fastening performance, increase the safety and reliability of transportation, and thus avoid safety accidents. [0004] In order to achieve the above object, the ...
