Abstract

The invention discloses an anti-loose retaining type connection structure, which comprises a bolt and a nut. The bolt comprises a screw rod and a limiting block located on one end of the screw rod andfixed to the screw rod; a center cavity is arranged in the screw rod; a first pore passage and a second pore passage communicating with the center cavity are arranged on a side wall of the screw rod;a push rod is arranged in a center hole; a pressing block is arranged on one end, close to the limiting rod, of the push rod; a first ejector rod and a second ejector rod movably connected with the push rod are arranged on one end, far away from the limiting block, of the push rod; axially arranged compression springs pressing against the first ejector rod and the second ejector rod are arrangedon one sides, far away from the push rod, of the first ejector rod and the second ejector rod; when the compression springs are at a natural state, one ends, far away from each other, of the first ejector rod and the second ejector rod penetrate through a first through hole and a second through hole so as to extend to the outer part of the screw rod; and a locked groove for the first ejector rod and the second ejector rod to insert is formed in an inner wall of the nut. According to the anti-loose retaining type connection structure provided by the invention, a connected workpiece is good in firmness, and cannot get loose and be separated.

Description

technical field [0001] The invention relates to the technical field of production and processing of forklift parts, in particular to an anti-loosening and anti-backward connection structure. Background technique [0002] The wheel hub is also called the rim, the steel ring, the wheel, and the tire bell. It is a barrel-shaped, center-mounted metal part that supports the tire on the inner profile of the tire. However, the existing bolt assembly used to connect the hub and the shaft is prone to loosening or even falling off due to the influence of various factors, and needs to be improved urgently. Contents of the invention [0003] Based on the technical problems in the above-mentioned background technology, the present invention proposes an anti-loosening and anti-backward connection structure. [0004] The present invention proposes an anti-loosening and anti-backward connection structure, including: bolts and nuts adapted to the bolts, wherein: [0005] The bolt include...
