[0002] The door closer is a hydraulic device similar to a spring on the door head. When the door is opened, it can be compressed and then released to automatically close the door. It has the function of a spring door, which can ensure that the door is accurately and timely closed to the initial position after being opened. The floor spring is a hydraulic door closer, but the device that compresses the spring is a worm gear instead of a gear or rack. Because the worm gear can rotate forward and backward, the floor spring can be used for doors that open in both directions, while the door closer can only be used for doors that open in one direction. The technical key of the floor spring is the bearing seat at the bottom of the main shaft, which determines the load-bearing level of the floor spring.
