?Types of Floor Springs and Their Uses

Floor springs are relatively unknown products to consumers. However, when it comes to the use of floor springs, many consumers should be familiar with them. Many public places choose floor springs to ensure the convenience of entering and leaving. Here, I will give you a detailed introduction to the uses and product types of floor springs, if you are interested, let's learn about them!

Uses of floor springs

A floor spring is a hydraulic door closer, and unlike other springs, the device that compresses the spring is a worm wheel instead of a rack and pinion. Floor springs are suitable for doors that open in both directions because the worm wheel of floor springs can rotate forward and backward, so they are generally used in the exterior doors of banks and companies so that it is convenient for the people who enter and exit. From the production point of view, the worm wheel structure of the floor spring makes the compression degree of the spring smaller than that of the rack and pinion driven door closer, and the force arm of the floor spring closing the door is also short, so the quality of the floor spring is very dependent on the structural design and processing accuracy. Moreover, the door plane of the two-way door opening has a great force on the floor spring, so the fluctuation range of the floor spring falls widely in price. There are many varieties of floor springs, but due to different testing methods, there is no comparability in the number of openings between the American standard, European standard and national standard. The price is also not the same. For our Chinese standard floor springs, they generally meet the requirement of opening test more than 500,000 times and are suitable for external doors with anti-theft requirements and low frequency of use.

Types of floor springs

Luxury beautiful type and economic beautiful type - These two types are similar in appearance and size, and the angle of application of the door is the same, and some characteristics are also similar. However, there are many differences hidden in the nature. The fan weight bearing force of the luxurious beautiful type is larger, and the economic beautiful type is applicable to one speed adjustment, while the luxurious beautiful type is applicable to two speed adjustments. The Deluxe Aesthetic type floor springs are mostly used in large buildings.

Super heavy duty and novel and light type - Super heavy duty floor springs are larger in appearance than others, and the maximum door weight is 230-300kg, and the applicable angle of the door is 1200mm-1500mm, which is very different from novel and light type floor springs. The novel and lightweight type of floor spring is small in appearance, with a door load capacity of only 50 kg and a door angle of 800-900 mm, but the characteristics of these two types of floor springs are the same: two-way opening of the center arm, 90° stop, and two-speed adjustment.

Fire and moisture resistant - These two types of floor springs have a similar scope of action, one being fire resistant and the other moisture resistant. The fire-resistant type is longer than the moisture-resistant type, but smaller in width and height than the moisture-resistant type. In terms of door load-bearing size, the fire-resistant floor spring is higher than the moisture-resistant floor spring, and the applicable width of the door is larger. Other characteristics are the same.

Through the above understanding of the types of floor springs and product usage, I believe that friends have a more comprehensive understanding of floor springs. When choosing a floor spring, the person concerned must judge which type of floor spring to choose according to the actual use, and pay more attention to the brand and quality of the product, and determine the service life of the floor spring.

There are several types of floor springs

As one of the primary accessories for doors and windows, the floor spring has always been one of the aspects that people outside the industry pay attention to, because the doors and windows, despite the quality of the main itself, but these accessories are still an aspect that can not be ignored, especially the floor spring, its effect is very significant, not only to ensure the quality of the doors and windows, and can also significantly increase the service life of the doors and windows. The floor spring consists of two major components. Its upper structure for the top shaft and the top shaft sleeve plate, the lower structure for the rotary shaft and base. Floor spring can not only make the door active closure, smooth operation, no noise, and can also adjust the speed of the door active closure. From the point of view of manufacturing, the worm gear structure of the floor spring so that the degree of tightening than the rack and pinion drive door closer, the force arm of the floor spring to close the door is also short, so the quality of the floor spring on the structure of the planning and processing accuracy of higher dependence. In addition, because of the two-way door opening door along the door plane has a great effect on the spring, so the grade of low floor spring life and high floor spring distance will be great. The basic equipment of the floor spring is the sky axis and the ground axis (or called the foot). Sky axis is the upper part of the door frame and door accessories, by a fixed in the door fan can be adjusted with a bolt pin type shaft and a fixed in the door sleeve. The floor spring can be used for all wooden, steel, aluminum doors and frameless glass doors with glass door clips.

There are several floor spring specifications

The floor spring planning 90 degrees to stop and 116 degrees without stopping, closing the door process from 90 degrees or 116 degrees of the position off back to 20 degrees of the position called closing speed, usually set about 5 seconds, 20 degrees back to 0 degrees for the locking speed is usually set at about 2 seconds, theoretically locking speed is slightly faster than the closing speed, so as to increase the locking force of the door, but in the actual use of the situation are now on the locking The speed is slower than the closing speed is to avoid the door touches the heel of the passing personnel, also known as the speed buffer, most of the floor spring back to zero will present a certain reset error, the normal floor spring reset error is usually within 1mm. HEINDA ground spring types are: HD-75/75V, HD-95, HD-212, HD-128, HD-220B, HD-208, HD-222, HD-818, K-6000, K-8300, HD-7300, HD-7305. HD-8400, HD-84, HD-8800, TS-80, HD-65, HD-850.

Suitable door width specifications are: 600mm, 700mm, 750mm, 800mm, 850mm, 900mm, 1000mm, 1050mm, 1100mm, 1200mm, 1250mm, 1500mm, 1600mm, etc.
