Name: Floor Spring, also known as Ground Closer or Floor Hinge.

Function: It is a type of automatic door closer installed beneath the door pivot, used for double-swing doors. It provides automatic closing and positioning functions.

Basic Configuration: Top pivot and bottom pivot (also called floor pivot). The top pivot is a component that connects the door frame and the door leaf at the upper part. It consists of a bolt-adjustable pin fixed to the door leaf and a pivot sleeve also mounted on the door leaf.

Working Principle:

Opening Process: When the door leaf is pushed open, it rotates around the axis of the top pivot and the connecting rod. The internal worm gear mechanism of the floor spring compresses the spring to store energy.

Closing Process: When released, the spring inside the floor spring releases energy, driving the worm gear to rotate in the opposite direction, thereby automatically closing the door. During this process, the hydraulic system controls the closing speed to provide cushioning and prevent a strong impact when the door shuts.

Positioning Principle: When the door is opened to 90°, the arched recess of the braking arm allows the door to remain at that position, functioning as a door stopper.
