The Structure And Use Of Floor Springs

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.

As a kind of hydraulic door closer, the basic configuration of the floor spring is divided into two major parts: the sky shaft and the ground shaft. The sky shaft mainly connects the door frame and the door fitting, and consists of a pin-type shaft fixed on the door, which can be adjusted with bolts, and a sleeve fixed on the door. Its worm gear design, which can be rotated forward and backward, can be applied to almost all wooden, steel, aluminum doors and frameless glass doors using glass door clips.

Precautions for installation of floor springs

1、The size of the groove is moderate, not too big or too small, too big affect the elegance, too small is a less stable material, the firm is not firm.

2、The position of the axis of the floor spring must be correct, and the plumb line or other things to find the vertical line must be used.

3、The thickness of cement or quick-drying powder used for stabilization is in line with the strength of the ground spring to ensure stability.

4、After slotting and stabilizing the floor spring, the cement or quick-drying powder must have sufficient strength before installing the door body to stop the ground spring from shifting and causing rework.

The use of floor springs

1、Closing speed is too fast, you should adjust the speed knob in time, if there is no response, you should check whether the ground spring is leaking oil, if there is oil leakage, please replace it in time.

2、If the floor spring is found to be leaking oil, it should be replaced in time, please do not continue to use it, there are safety hazards of oil leakage.

3, the door only opens in one direction, any artificial strong closing action will lead to damage to internal components resulting in one-way open or damage, so it should automatically return to close the door is better.

4、If the two doors are misaligned, you should check whether the lower box of the floor spring is fixed on the concrete floor, and adjust the up and down front and rear adjustment knob.

5、It is strictly forbidden to grind the center spindle head of the floor spring without permission.

The speed adjustment method of the floor spring

1、The first section speed and the second section speed can be adjusted to the appropriate speed independently.?

2、The speed of closing the floor spring is divided into the speed of starting to close (the first speed knob, range about 90 degrees - 20 degrees) and the speed of closing completely (the second speed knob, range about 20 degrees - 0 degrees).?

3, start closing the door of the speed (the first paragraph speed) should be faster than the second paragraph speed.

Of course, many people do not know how to buy floor springs, in fact, the focus of buying floor springs is to determine the weight-bearing of the glass door, and then to make a selection of different models of floor springs. The standard is qualified product ≥ 300,000 times open, superior product ≥ 500,000 times open, the foreign standard is at least 500,000 times so that the quality of the floor spring should reach 500,000 times. 500,000 times is not arbitrarily said to have, it is necessary to pass the test.

HEINDA's floor spring has test reports，if you are interested in our floor spring or you are observing the content of the floor spring. If you are interested in our floor springs or you are looking at the content of our floor springs, you are always welcome to discuss it with us.
