What is a floor spring?

The floor spring is a hydraulic door closer, but the device that presses the spring is a worm gear rather than a gear rack. Because the worm gear can rotate in both directions, 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 load-bearing seat at the lower part of the main shaft, which determines the load-bearing level of the floor spring.

What is the principle of floor spring?

The working principle of the floor spring is to use a turbine device to compress the spring and achieve the closure of the door. The floor spring is divided into two parts: the sky axis and the earth axis. The earth axis is fixed on the door frame, and the sky axis is used to connect the door leaf and the door frame. The release of spring pressure pushes the sky axis, allowing the door to close freely.

What is the structure of the floor spring?

The basic configuration of a floor spring is the axis of the sky and the axis of the earth (also known as the foot). The sky axis is an accessory that connects the door frame and door leaf at the upper part, consisting of a bolt adjustable pin type axis fixed on the door leaf and a shaft sleeve fixed on the door leaf. The axis of heaven and earth can be applied to almost all wooden, steel, aluminum alloy doors, and frameless glass doors that use glass door clips.
