Floor Spring

The floor spring is a hydraulic door closer, and the device that compresses the spring is a worm gear instead of a rack and pinion. Since the worm gear can rotate forward and reverse, the floor spring can be used for doors that open in two directions, while traditional door closers can only be used for doors that open in one direction.

The floor spring consists of two upper and lower metal plates and a spring in the middle. Its structure is relatively simple. The upper and lower metal plates can ensure the stability of the device, while the spring in the middle serves as sound insulation and shockproof. The spring coefficient of the floor spring is high, which can greatly reduce the transmission of vibration energy, thereby achieving good sound insulation and shockproof effects. In addition, the floor spring also has a certain load-bearing capacity, and its load-bearing level is determined by the load-bearing seat under the main shaft.

Floor springs are suitable for a variety of occasions, such as subways, highways and other places where sound insulation, shockproof and equipment stability are required. When selecting a floor spring, factors such as the weight of the door body, door frame, and wind pressure need to be considered to ensure the applicability and stability of the floor spring. In addition, you also need to pay attention to the aspect ratio, that is, the ratio of the height and width of the door leaf, to ensure the normal use of the door leaf.

In short, as a hydraulic door closer, the floor spring has the advantages of simple structure, good sound insulation and shockproof effect, and wide application range. It is widely used in various occasions where the stability of the equipment and sound insulation and shockproof are required.
