Introduction to door closers:
The door closer is a spring-like hydraulic device on the door head. When the door is opened, it can be compressed and released to automatically close the door. It acts like a spring door and can ensure that the door is opened accurately and timely to the initial position. .
Modern hydraulic door closers (referred to as door closers) began with a patent registered by the Americans in the early twentieth century. It is different from traditional door closers in that it achieves a buffer effect by throttling the liquid in the door closer. . The core of the design idea of the hydraulic door closer is to realize the control of the closing process, so that the various functional indexes of the closing process can be adjusted according to the needs of people.
