[0023] Furthermore, the lifting mechanism 1 further comprises an outer sleeve 13, a fixed base 14 and a pulley 15. The outer sleeve 13 is a tubular structure with an opening at one end. The outer sleeve 13 has a tube space 133 inside which the lifting rod 11 and the pneumatic rod 12 can be lifted up and down. The fixed base 14 is arranged at the bottom of the tube space 133.

One end of the piston rod 122 is provided with a piston 1221 which is inserted into the pneumatic cylinder 121 for mating connection. The piston 1221 is arranged in the pneumatic cylinder 121. At this time, the interior of the pneumatic cylinder 121 is a closed space 1211, and the closed space 1211 is filled with compressed gas. The other end of the piston rod 122 is mounted on the fixed base 14, so that the piston rod 122 is fixed on the fixed base 14, so that the control unit 2 can lift the lifting rod 11, and the lifting rod 11 drives the air cylinder 121 to cooperate with the piston rod 122 to perform piston movement along the inner space 133 of the tube.

[0024] Furthermore, in the utility model, a damping ring 123 is provided on the piston 1221, and the damping ring 123 is arranged inside the pneumatic cylinder 121 in cooperation with the piston 1221. The damping ring 123 can provide stable damping, so that the position control of the pneumatic rod 12 during the lifting process will be more precise, and can meet the use requirements of higher precision. At the same time, it can reduce the wear problem of the pneumatic cylinder 121 and the piston rod 122, and can improve the stability and working efficiency of the entire pneumatic rod 12.

[0025] In this embodiment, the lifting rod 11 is provided with a pair of clamping strips 111, and the inner tube space 133 is provided with a pair of assembly grooves 1331. The lifting rod 11 is limited and installed in the assembly grooves 1331 by the clamping strips 111, so as to realize the rapid and foolproof installation of the lifting rod 11. Furthermore, in order to make the lifting rod 11 move more smoothly in the inner tube space 133. Among them, the lifting rod 11 is provided with a plurality of pulleys 15 and limit blocks 16, and a pair of pulley limit grooves 1332 are provided in the inner tube space 133, and the pulleys 15 and limit blocks 16 are installed in the pulley limit grooves 1332 in cooperation with the lifting rod 11. The pulley 15 cooperates with the lifting rod 11 to achieve a more stable up and down movement along the space 133 in the tube. The cross-section of the lifting rod 11 is square, so that the lifting rod 11 will not shake when sliding up and down in the space 133 in the tube with a square cross-section. Limit blocks 16 are set on both sides of the lifting rod 11 to further prevent the lifting rod 11 from shaking when sliding up and down in the space 133 in the tube.

[0026] The opening of the outer sleeve 13 is provided with an armrest limiting groove 131 and a screen-hanging limiting groove 132, which are used to limit the movable height of the control unit 2 and the screen-hanging assembly 3. Specifically, the control unit 2 is connected to the lifting rod 11 through the armrest limiting groove 131, one end of the connecting arm 4 is installed on the lifting rod 11 through the screen-hanging limiting groove 132, and the screen-hanging assembly 3 is installed on the other end of the connecting arm 4.

The handle mounting plug 211 is matched and connected with the handle mounting hole 112 to fix the handle 21 on the lifting rod 11. The handle cover 22 is sleeved on the handle 21 and is used to protect the handle 21 to prevent the handle 21 from being damaged due to long-term use.

[0028] In the utility model, the pneumatic rod 12 is controlled to be raised and lowered by the lifting rod 11, and the enclosed space 1211 inside the pneumatic cylinder 121 is filled with compressed gas. When the control unit 2 lifts the lifting rod 11 to rise and adjust, the lifting rod 11 drives the pneumatic cylinder 121 to move upward, and the gas in the enclosed space 1211 increases the air pressure as the pneumatic cylinder 121 rises, thereby generating an outward thrust, i.e., a supporting force, which enables the pneumatic rod 12 to overcome its own weight and external load; when the control unit 2 pulls down the lifting rod 11 to descend and adjust, the gas in the enclosed space 1211 decreases the air pressure as the pneumatic cylinder 121 descends, which can help the lifting rod 11 maintain its position or descend slowly.

[0029] The utility model relates to a lifting bracket, in which a pneumatic rod 12 can position a lifting rod 11 at different positions, and can achieve arbitrary position positioning without an external release mechanism / particularly suitable for large load changes within a limited load range. The pneumatic rod 12 controls the compression and expansion of the internal gas to achieve smooth lifting and lowering, thereby improving the stability of the lifting bracket. Among them, in the utility model, the damping ring 123 provides damping properties to the pneumatic rod 12, so that the pneumatic rod 12 can stay at any position during the lifting process. To change the working position, external force must be applied by hand. When the external force is removed, the pneumatic rod 12 can remain in this position, so that the user can freely adjust a more suitable viewing height according to their own needs, giving the user a better viewing experience.
