INTRODUCTION
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
FEATURES

SPECIFICATION
INSTALLATION STEPS
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:What kind of material does spring have?
- Alloy spring steel: alloy spring steel is used to make spring or other elastic parts of steel. Spring is generally under alternating stress, the fatigue failure is a common failure forms, therefore, alloy spring steel must have high yield and yield ratio (s/ b) and the anti fatigue performance of elastic limit, and to ensure that the spring has enough elastic deformation ability and can withstand greater load. At the same time, alloy spring steel also requires a certain plasticity and toughness, a certain hardenability, not easy to decarburization and not overheating. Some special springs also require heat resistance, corrosion resistance, or a stable elasticity over a long period of time. Medium carbon steel and high carbon steel can be used as springs, but because of its hardenability and low strength, it can only be used to make smaller cross-section, less force of the spring. Alloy spring steel can produce important spring with large cross section and high yield limit
- Q:What is an independent bagged spring?
- The characteristics of independent bagged springs is independent bagged spring each spring can be independent of support, stretching alone, completely conform to the body curve, so that all parts of the body are the best care, with ergonomic, closely supporting effect. Spring tube respectively operation, a force, not elsewhere, even if the pillow was over, it will not affect the sleeping of another, especially by adding a layer of high elastic cotton blanket and wave type sponge bed, bump by using body wave sponge flip natural movement to achieve the massage and health care enjoy the ultimate role of sleep.
- Q:Can springs be used for support?
- If there is a condition, the upper and lower parts of the spring are mounted, similar to the bearing parts, and more thoroughly separated from the gears.
- Q:Spring dynamometer and spring balance what is the difference
- The principle is similar, but the uses are somewhat different
- Q:Stainless steel and spring steel hardness, who is hard?
- Hardness is checked by indentation, not by pliers.Stainless steel, of course
- Q:How to process Spring Steel
- Ha ha, friend,At first I thought it was a springFirst, you want to buy hot, or annealed spring steel, the standard number is GB/1222-2007< more than and 10 grades, including you 65 and 60 Si 2 A> Meng MengI'll probably help you figure it out. There are so many processes1 turning 2 milling machine processing openings 3 heat treatmentWell, I'm going to work, tooI hope my answer is of some use to you
- Q:The glass door spring is broken. How much would it cost to change it?
- The price of the spring itself is about 200-800, plus part of the labor cost. After all, it's very expensive. There are about 150 of the spring, but the quality is not good, or safety first. Labor costs are probably about 120. Specific prices should be based on your actual situation, you and the master speak.
- Q:What kind of spring has the best performance?
- Spring verticality, verticality is bad, will directly affect the strength and life.
- Q:I buy a spring made of 1.2mm steel wire from a hardware store that needs quenching
- In general, hot bending spring coil spiral spring and disc spring of hot stamping, preferably in hot forming and quenching by the heat immediately. In this way, the heating and the decarburization degree of the spring can be omitted, and the surface quality of the spring can be improved both economically and at the same time.
- Q:What are the main functions of spring?
- Absorb vibration and impact energy, such as damping springs in various kinds of vehicles and springs of various buffers
