The modern hydraulic door closer (hereinafter referred to as the door closer) began with a patent registered by the Americans at the beginning of the 20th century. It is different from the traditional door closer in that it achieves buffering effect by throttling the liquid in the door closer. The core design idea of the hydraulic door closer is to realize the control of the closing process so that various functional indicators of the closing process can be adjusted according to the needs of people.
