Abstract

The invention discloses a dustproof cover for a car coupler device, and relates to the technical field of dustproof covers. The dustproof cover comprises a dustproof cover body, a bowl-shaped groove is formed in the upper end face of the dustproof cover body, a circular groove is formed in the lower end face of the dustproof cover body, the circular groove and the bowl-shaped groove are located inthe same horizontal line, mounting holes are formed in the corners of the dustproof cover body, a sealing strip is arranged on the lower end face of the dustproof cover body, a closed area is definedby the sealing strip, and the circular groove and the bowl-shaped groove are located in the closed area. The invention further discloses a preparation method of the dustproof cover for the car coupler device. The dustproof effect of the dustproof cover is improved, the strength of the dustproof cover is improved, abrasion resisting performance is greatly improved, and the service life of the dustproof cover is prolonged.

Description

Technical field [0001] The present invention relates to the technical field of dust cover, in particular to a dust cover for a coupler device and a preparation method thereof. Background technique [0002] The coupler is a vehicle component used to realize the connection between the locomotive and the vehicle or the vehicle and the vehicle, transmit traction and impact force, and keep a certain distance between the vehicles. The coupler is divided into two types: upper-acting and lower-acting according to the opening mode. The coupler plays an important role in ensuring the safety and reliability of the vehicle coupling. Therefore, the vehicle technology principle stipulates that the coupler of various buffer couplers must be equipped with protective devices. [0003] The current protective devices on the market cannot prevent abnormal wear of the coupler due to foreign objects such as muddy water, ice, rain, etc., which shortens the service life of the coupler and may even cause d...
