Detailed Description

The present invention is further illustrated by the following figures and specific examples, which are to be understood as illustrative only and not as limiting the scope of the utility model, which is to be given the full breadth of the appended claims and any and all equivalent modifications thereof which may occur to those skilled in the art upon reading the present specification.

Examples

As shown in fig. 1, 2 and 4, a vertically liftable cabinet is damped using a gas spring 13. In the prior art, a coil spring is used as a damping mechanism, if the bearing capacity is strong, the elasticity of the coil spring needs to be increased, but if the elasticity of the coil spring is too large, the object carrying part can be recovered too fast, the use feeling is poor, and the potential safety hazard that a user is injured by rebounding exists. The utility model uses the combination of the gas spring and the lifting wheel 12, can enlarge the moving distance, leads the moving stroke to reach two times or more than the moving stroke of the telescopic rod of the gas spring, greatly enlarges the distance, simultaneously, because the gas spring is provided with damping, no matter how strong the resilience force is, the recovery speed can not be too fast, solves the contradiction between the too fast recovery and the bearing capacity, and simultaneously ensures the safety.

The travel guide rail 14 is used, so that the lifting wheel 12 moves in the guide groove, the travel route of the lifting wheel 12 is guaranteed to be vertical and not deviated, the lifting wheel is more stable in movement, is not interfered by other factors, can vertically run in any environment, and is suitable for various scenes. The effect of using the pulley can also be achieved by matching the gear with the rack.

As shown in fig. 3 and 5, the lower parts of the shoulders of the fixed rod 22 and the moving rod 23 in the locking assembly 2 penetrate through the locking box 21, and are limited by the locking box 21, so that the stability is enhanced.

A spring located between the locking tab 24 and the upper cross plate 212 cooperates with the locking tab 24 to effect locking.

When a user applies downward force to the bottom handle, the moving rod 23 in the locking assembly 2 is triggered to move downwards, the force of the shoulder part of the moving rod 23 on the locking tongue piece 24 is gradually reduced until the locking tongue piece 24 is in a horizontal state, the spring is in a relaxed state, the locking assembly 2 is unlocked, and if the user still pulls downwards, the moving rod 23 is gradually clamped by the hole in the moving rod 23 on the locking tongue piece 24 due to friction force, the spring is compressed by the locking tongue piece 24 and the fixed rod 22, downward elastic force is generated, and the friction force resists against each other, so that locking is realized. If not having released the handle to the minimum, the effect of locking still can be reached in the same way, reaches arbitrary position locking promptly, and is very safe and convenient, and the use feels outstanding.

When a user applies upward force to the bottom handle, the locking tongue piece 24 is forced by the shoulder of the moving rod 23 to jack upwards, so that unlocking can be achieved at a horizontal position instantly, the telescopic rod of the air spring naturally faces downwards to drive the lifting wheel to face downwards, the moving end of the flexible cable faces upwards, the loading part is pulled to automatically move upwards to retract, and similarly, the spring is still compressed, and only the compression direction is different, and position locking can be achieved in any process.
