Product Description:



Floor Spring is used for glass door, and they can be used together with door clamp. Floor Spring can be opened with double sizes, and on this point, it is different from that of door closer, which can just be opened by one size.  The key of technique lies on the loading seat under the main bearing, which decides the level of loading on the floor spring. Usually it can be opened from 300thousand or 1million times





u  Applicable for glass doors, wooden doors and the glass doors of metal frame and wooden frame.

u  Floor spring comply to EN 1154 and GB standard , and fire-rated EN1634 standard.

u  Maximum 500000 cycles tested without damage or maximum 7 years guarantee.

u  Double ways opening with smoothly movement, hold-open at 90°.

u  Closing speed and latching speed adjustable, latching point accurately at 0°

u  Stainless steel cover plate, satin or mirror surface available.

u  High quality casting iron floor spring body with 2 layers anti-rust coating.

u  All spindle types available for different countries.

u  Germany hydraulic machine oil and sealed rings, keep perfect working in cold temperature.

1.      Draw lines and make floor spring pivot center and door-nip pivot coincide with each other.

2.      Drill holes on the floor according to the instructions. The sizes of the holes must tightly match the floor spring.

3.      Place the floor spring into the holes and position it.

4.      Raise the door leaf installed with door-nip, and insert the floor spring pivot into the hole of the door leaf.

5.     Adjust the screws at three directions. Make them vertical and the upper and lower pivot center coincide with each other.

6.      Adjust the speed of door closing.

7.      Put the decoration cover on the floor spring.

Q:Displacement problems in a spring oscillator
In short, in vibration and wave, it is not easy to make mistakes when we grasp the difference and relationship between "displacement" and "displacement relative to the balance position"
Q:How to process Spring Steel
The available oxygen converter furnace and open hearth furnace or general production of spring steel; high quality spring steel or better quality with special properties, furnace or vacuum refining furnace. The content of carbon, manganese, silicon and other major elements in spring steel is narrow, and the chemical composition must be strictly controlled during smelting. When the silicon content is high, it is easy to form bubbles and other defects. After the ingot is rolled and rolled, the cooling is not easy. Therefore, the raw materials used for smelting must be dry, as much as possible to remove gas and inclusions, and to avoid overheating of the steel.
Q:Hydraulic diagram of the one-way valve has two kinds of drawing, with a spring, without a spring, what is the difference between automatic reset function is not? Without a spring, it will not be repeated
The simplified method of drawing without springs is the same
Q:I buy a spring made of 1.2mm steel wire from a hardware store that needs quenching
Spring: Spring quenching hardening is the steel is heated to the critical temperature of Ac, or Ac: the above heat preservation time, the austenite with greater than the critical cooling rate of rapid cooling, so as to obtain the heat treatment method of martensite.
Q:What kind of spring has the best performance?
Number of coils, coil number is greater than the difference between the 0.25 circle, will directly affect the intensity of emotion.
Q:What kind of production equipment does spring factory usually have?
Spring testing machines; fatigue testing machines; torsion testing machines; spring tension and compression testing machines
Q:What's the spring material to?
There are many kinds of spring steel, the most commonly used are 65Mn and 60Si2Mn.
Q:Cold rolled coil spring spring and difference "
Difference: the main annealing time is different. In the production process, is the first volume of coil spring and annealing, and spring is the first cold roll annealing, and then roll. Similar to cold rolling and hot rolling of steel.Note: spring making methodProduction method of cold rolled coil spring: to stress annealing, end surface grinding, (blast), (the whole school), (BKS), standing or forcing treatment, surface inspection and treatment.Production method of coil spring: blanking, end processing (rolled or forged flat), heating, coiling, quenching, tempering, grinding end to compression to (load test), shot peening (cleaning), coating.
Q:What are the categories of springs?
A compression spring is spring under axial pressure, the material section in which are round, rectangular and is also useful multi strand steel rayon coiled spring, generally for pitch, compression spring shapes: cylindrical, conical, convex and concave and a small amount of non circular, will there is a certain gap between the ring and the ring compression spring, when subjected to external load when the spring contraction deformation, deformation energy storage.
Q:Want to practice how to use pectoral muscle spring expander
The most simple way you can lie on the bed or on the floor and chest stretching is very effective and pay attention to more, so as not to hurt the small set of muscles.It takes at least one month to bear fruit
