Eccentric Shaft Floor Spring Fittings Frame Door Shaft
What is a floor spring ?
A floor spring is actually a hydraulic door closer, except that the device that compresses the spring is a worm gear instead of a rack and pinion. 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 to the floor spring is the load-bearing seat on the lower part of the spindle, which determines the load-bearing level of the floor spring. Because the ground spring for two-way opening is not like the door closer, the ground spring needs to carry the weight of the door body, so that the weight of the door body plays a decisive role in the selection of the ground spring, but of course, the door width and wind pressure are also very important for the selection of the ground spring model.
