Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing.

[0012] Such as figure 1 As shown, an improved bolt structure includes a thread 10, a nut 11, a screw 12 and a groove 13, the nut 11 and the screw 12 are integrally formed, the nut 11 is provided with a groove 13, and the screw 12 is provided with a thread 10. The outer surface of the nut 11 is provided with a pattern layer 14, the nut 11 is cylindrical, and the groove 13 is cross-shaped.

[0013] The method of use is like ordinary bolts, which are fastened into the threaded holes. There is a pattern layer on the surface of the nut, the structure design is reasonable, it has the function of anti-slip, and it is convenient to use.

Abstract

The invention discloses an anti-loosening nut, and belongs to the field of bolts. The anti-loosening nut comprises a screw body, a screw disc, an internal threaded hole, a threaded wall surface, a threaded surface and an annular groove, one side of the screw body extends outwards to form the screw disc, the threaded wall surface higher than the screw disc is arranged at the outer end edge of the internal threaded hole in an extending manner, the threaded surface connected with the internal threaded hole in an extending manner is arranged on the inner edge surface of the threaded wall surface, and the annular groove is formed between the outer edge surface of the threaded wall surface and the screw disc. The anti-loosening nut has the advantages that the threaded wall surface can be pressed to deform and expand towards two sides when a screw is screwed with a nut, the form of a continuous thread is changed, a gap formed in combination of screws, and the combined screws are prevented from loosening.

Description

technical field [0001] The invention relates to a bolt, in particular to an improved bolt structure, belonging to the field of bolts. Background technique [0002] A bolt is a type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten and connect two parts with through holes. [0003] However, the surface of the general bolt and nut is smooth, which causes installation inconvenience, so it is necessary to find a new bolt to solve the above shortcomings. Contents of the invention [0004] Aiming at the above-mentioned problems in the prior art, the present invention provides an improved bolt structure. The surface of the nut is provided with a pattern layer, which has an anti-skid function and is convenient to use. [0005] In order to achieve the above object, the technical solution adopted by the present invention is: including thread, nut, screw rod and groove, the nut and the screw rod are integr...
