Abstract

The invention discloses a connection fixing device with a separation / loosening preventing structure. The connection fixing device comprises a screw, a nut and a lock washer, wherein at least two lock round holes are formed uniformly in the lock washer, propping round holes communicated with the lock round holes are formed in the centers of side surfaces of the lock washer, arc-shaped position locking elastic pieces are arranged in the lock round holes, L-shaped clamping blocks are arranged at outer side ends of the arc-shaped position locking elastic pieces, middles of the L-shaped clamping blocks are connected to the edge of the lock washer through rotating shafts, clamping holes are uniformly formed in the surface of the nut, propping columns are arranged in the propping round holes, and bottom ends of the propping columns are fixed in centers of outer arc edges of the arc-shaped position locking elastic pieces. The connection fixing device is reasonable in structural arrangement, the screw and the nut are not prone to loosening or separation even in a vibration environment, the technical defect that the screw and the nut are prone to loosening during use in the traditional technology is overcome, and the connection fixing device is good in use stability and high in adaptability.

Description

technical field [0001] The invention belongs to the technical field of connection and fixing, and in particular relates to a connection and fixing device with an anti-loosening structure. Background technique [0002] Bolts are a commonly used connection structure in the connection of equipment and various structures. Bolts are mainly composed of screws and nuts. Since the screw and the screw are threaded, they are easy to loosen or fall off during use. Traditional technologies mainly use gaskets and other structures. Buffering, although it can achieve bolt loosening to a certain extent, it is also easy to loosen under low torque or vibration environment, and it is difficult to achieve the ideal anti-loosening technical effect, so the applicability and practicability are limited. Contents of the invention [0003] The purpose of the present invention is to provide a connection and fixing device with a reasonable structure and good stability in use and an anti-loosening str...
