Abstract

The invention provides an integral type anti-falling bolt structure which comprises a bolt, a connecting piece and a fixing piece, and a threaded rod of the bolt penetrates through an inserting hole of the connecting piece and is connected into a threaded hole of the fixing piece in a threaded mode. A positioning protrusion is arranged on the outer ring of the end, connected with the nut, of the screw, and the diameter of the positioning protrusion is larger than that of the insertion hole. A containing groove is formed in the top end of the fixing piece threaded hole, and the positioning protrusion is located in the containing groove. An annular caulking groove is formed in the connecting position of the positioning protrusion and the nut, the caulking groove is opposite to the connecting piece in position, and an elastic piece is arranged in the caulking groove. When the integral type anti-falling bolt structure is used, the elastic piece can be installed in the embedding groove in advance, then the positioning protrusion is pressed into the inserting hole in advance, an integral part is formed, so that integral installation of the connecting piece and the fixing piece is achieved, and the repeated bolt installing process on an assembly line is reduced. Meanwhile, due to the arrangement of the elastic piece, the friction force between the connecting piece and the bolt can be increased, and the effects of fixing the positions of the connecting piece and the bolt, sealing and damping are achieved.

Description

technical field [0001] The invention belongs to the technical field of fasteners, and in particular relates to an integral anti-loosening bolt structure. Background technique [0002] With the process of industrialization, in order to improve the economic benefits of enterprises and reduce the operating costs of enterprises, higher requirements have been put forward for the production efficiency of products in various industries, especially the strict control of the action time of each process in the assembly line. Improve the product output rate per unit time. [0003] In the traditional general assembly process, due to the complexity and diversity of the installed parts, it is often necessary to carry out repeated tasks such as taking connectors and bolts many times, which limits the production efficiency of the assembly line, and special processes require multiple people to cooperate with each other. Caused a waste of human resources. The present invention is mainly to ...
