Abstract

The invention relates to the technical field of firm connecting pieces, in particular to a connecting bolt. The connecting bolt comprises a bolt head, a threaded rod integrated with the bolt head, and a gasket which sleeves the threaded rod, wherein a plurality of circular notches are opened in the peripheral wall of the threaded rod in the axial line direction, an elastic component is arranged in each circular notch, and press blocks for pressing the elastic components in the circular notches are firmly arranged on the gasket. A plurality of elastic components are assembled in the circular notches in a one-to-one correspondence mode, the gasket sleeves the threaded rod, the press blocks on the gasket compress the elastic components, when connecting spare parts, the gasket contacts with the spare parts, and the firm connection is realized through screwing down the threaded rod; by means of the elastic components, there is a certain elasticity between the gasket and bolt head, and then the hard damage of the gasket to the spare parts is lowered.

Description

technical field [0001] The invention relates to the technical field of fixed connectors, in particular to a connecting bolt. Background technique [0002] Bolts usually play the role of connecting and fastening parts; in specific assembly, it is necessary to put a washer on the bolt, and rely on the elastic force of the washer to increase the friction force, so that the bolt is firmly connected and prevents loosening. This connection method It is the direct contact between the gasket and the parts, which will cause damage to the surface of the parts. Contents of the invention [0003] In view of the above technical problems, the present invention provides a connecting bolt with a simple structure, which can generate a certain degree of elasticity between the washer and the parts, thereby reducing the hard damage caused by the washer to the parts. [0004] Realize the technical scheme of the present invention as follows: [0005] A connecting bolt, comprising a bolt head,...
