Description

technical field [0001] The 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 the traction force and the impact force, and keep a certain distance between the vehicles. According to the opening method, the coupler is divided into two types: the upper-action type and the lower-action type. The coupler plays an important role in ensuring the safety and reliability of the vehicle connection. Therefore, in principle, the vehicle technology stipulates that the coupler of various buffer couplers must be equipped with protective devices. [0003] At present, the protection devices on the market cannot prevent abnormal wear of the coupler caused by foreign objects such as mud, ice, and rainwater, thereby shortening the se...
