The principle and working mechanism of air pressure rod

1、 The principle and working mechanism of air pressure rod
The office chair air pressure rod utilizes the change in pressure of a sealed gas inside the rod to achieve the lifting or lowering of the chair. Specifically, the air pressure rod contains a piston and a valve inside. When pressure is applied to the bottom of the chair, the valve opens, allowing gas to flow into the piston. As gas flows in, the pressure inside the pressure bar gradually increases, causing the chair to rise; On the contrary, if the pressure at the bottom is reduced, the valve closes, gas flows out, and the pressure inside the pressure rod decreases, causing the office chair to lower. Therefore, the principle and working mechanism of the pressure rod are based on the pressure principle of solids and gases.
2、 Classification and characteristics of air pressure rods
According to the structure and function of the air pressure rod, it can be divided into the following types:
1. Fixed air pressure rod: usually used in situations where frequent height adjustment is not necessary, such as seats in sports stadiums or shopping centers. This type of air pressure rod has the characteristics of stability and strong load-bearing capacity.
2. Self elevating air pressure rod: an air pressure rod that can be quickly lifted and lowered. When the weight of the human chair is applied to the air pressure rod, the air pressure rod automatically rises and loads a linear spring, making the chair height automatically adapt to the body shape. The characteristics of this type of air pressure rod are adjustable height, high load-bearing capacity, and simple operation.
3. Rotating air pressure rod: mainly used in situations that require left and right rotation or adjustment of sitting posture, such as office chairs, beauty chairs, etc. The advantages of this type of air pressure rod are convenient rotation and strong flexibility.
In summary, the principle and working mechanism of the office chair air pressure rod is to use the pressure principle of solid and gas, and adjust the height of the chair seat through the pressure change inside the closed gas. In different situations, different types of air pressure rods can be selected to meet the needs, such as fixed air pressure rods, self elevating air pressure rods, and rotating air pressure rods.
