The hidden door closer achieves automatic door closure through an internal hydraulic or mechanical transmission system:
Opening stage: When the door is opened, it drives the transmission mechanism inside the door closer (such as the rack plunger or cam) to move, compresses the reset spring, and stores elastic potential energy.
Closing stage: Release elastic potential energy, drive the transmission mechanism to move in reverse, slowly close the door body, and at the same time, the hydraulic system controls the closing speed through the throttle valve core to achieve buffering effect.
Positioning function: Some models are equipped with a sliding groove positioning device, which can stop the door at a specific angle and facilitate personnel passage.
