Gas springs are commonly called support rods in the industry. From the current point of view, the use of support rods is very wide, ranging from automobile and motorcycle industry, machinery industry, electronic industry to transportation, fitness sports, medical equipment, and ubiquitous. The gas spring needs to be installed as far as possible down the piston rod during use, so as to ensure the best damping effect and cushioning performance. The gas spring should not be subjected to tilting force or lateral force during work, and must not be used as a handrail, which is very dangerous.
In order to ensure the reliability of the seal, the gas spring must not damage the surface of the piston rod, and it is strictly forbidden to apply paint and chemical substances on the piston rod. It is also not allowed to install the gas spring in the required position before spraying or painting. Remember that the piston rod must not rotate to the left. If you need to adjust the direction of the joint, you can only turn it to the right. This can also be rotated to a fixed direction. The size of the gas spring should be reasonable, the size of the force should be appropriate, and the stroke size of the piston rod should be spaced, and it cannot be locked. This will be a problem for future maintenance.
The connection point of the gas spring installation connection point should be as perpendicular as possible to the center line of rotation when the gas spring swings, otherwise it will affect the normal expansion and contraction of the gas spring, and even jam or abnormal noise.
Gas spring is a kind of liftable spring that can save effort. It can be divided into self-locking gas spring (such as the bottom of the seat lift, the backrest of the boss chair, etc.), and the non-self-locking gas spring (such as the lift of car trunk and closet door) Support), the structure of the gas spring is mainly composed of a sleeve, a piston and a piston rod. High pressure air or high pressure nitrogen is added to the sleeve. Due to the unequal area of the two ends of the piston, the pressure difference is generated, which pushes the piston and the piston rod to move and supports the person. Or heavy objects.
Compression-type gas springs have four types of joints: single-piece, single-ear, binaural and universal ball joints, followed by single-piece, single-ear, binaural and universal ball joints. In the design, the matching joint type should be selected according to the specific conditions of the installation location and the gas spring specifications. It is recommended to use the universal ball head type. This type of gas spring can automatically adjust the connection angle during the working process, thereby eliminating the lateral force in the gas spring working, and is especially suitable for occasions that require high installation accuracy. If the installation space is limited, the single-ear type can be used. This type of gas spring has a simple structure and requires less space for installation, but it cannot eliminate the lateral force caused by different shafts during the working process. Therefore, additional design of gas spring pins is required The shaft is connected to it. In short, no matter which type of joint is selected, it must be ensured that the door (cover) opens and closes smoothly without interference or jamming after the gas spring is installed.
