[0002] As a common structure in household products, the cover plate structure is usually installed in cabinet doors, room doors, windows and other locations. To facilitate the opening and closing of the cover plate structure, damping devices are usually provided on both sides of the cover plate to ensure that the cover plate will not suddenly fall and hit people's hands when it is closed. However, the existing cover plate damping devices cannot be used interchangeably. Consumers need to manually distinguish between left and right during installation, which sometimes leads to installation errors and delays in the installation process. If one of the paired damping devices is damaged, it will affect the stability of the entire cover plate structure.

[0003] At the same time, the existing dampers are fixed torque dampers, which are only allowed to be used within a certain range. If they exceed the damping range, they will lose the damping effect, which will cause safety problems. In order to cope with actual use, dampers with different torque specifications must be produced. However, dampers with different torques will bring many problems during processing and actual use, such as production, appearance, installation, packaging, transportation, etc. The wide variety of dampers brings huge pressure to manufacturers and also causes many inconveniences for users to actually purchase and use.
