The height-adjustable table can be adjusted directly, which saves the cost of purchasing another table.

2. Any product has common characteristics, the more complex the structure is, the higher the possibility of failure will be. To achieve the purpose of adjustable, the height adjustable table must have movable parts, which are generally realized through the hardware. If the strength of the fittings is not enough, the problem of looseness will occur after a long time. It will shake and even make noise while using it every time. This kind of table is not as comfortable as a common desk.

3. Let’s take a look at the cost performance of height-adjustable tables for children. The price of such products varies greatly in the market.

Height-adjustable tables are very common in our lives, especially in offices and schools. In many schools, it has been updated to height-adjustable tables, but how much do you know about the lifting principle of height-adjustable tables? Let’s learn it together.

1. Principle of pneumatic lift chair

The pneumatic lift chair is a new type of chair. There is a cylinder in the lift chair, the piston rod in the cylinder moves up and down to control swivel chair lifting.

2. Principle of hydraulic lift chair

As the key part of the hydraulic lift chair, the hydraulic jack is driven by the hydraulic pump manually. Through the hydraulic system transmission, the cylinder or piston is used as the lift. Hydraulic jacks can be divided into integral and separated types. The integral pump is integrated with the hydraulic cylinder; the separated pump is separated from the hydraulic cylinder, and connected with a high-pressure hose in the middle.

3. Principle of spiral lift chair

The basic principle can be summarized by “screw twisting”. The chair position is locked through the self-locking of the screw pair. It has the advantages of a simple structure and high security. In general, there would be no potential safety hazards. It should be noted that the bolts and nuts of spiral lift chairs are easy to rust, so the durability is not very good. In addition, after a long time of use, the screw connection part is easy to loosen due to wear and tear.

4. Principle of fixed position lift chair

The legs of such lift chairs are composed of two parts, and only two parts of components are used, then connected by screws, which is relatively safe. However, it is connected by screws, so the screws must be screwed before and after each lifting, and the operation is not very convenient. Moreover, such kind of lift chairs can only achieve fixed position lifting, and the flexibility is not very good.

5. Principle of electric lift chair principle

Linear drive electric push rod lifting device The electric push rod lifting column is a new linear lifting actuator, which is mainly composed of a motor, push rod and control device, and can realize remote control and centralized control. It adopts a four-sided guide structure design and DC electric push rod drive so that the electric push rod lifting column has the advantages of stable lifting and quiet.
