As shown in fig. 1-5, a screen lifting mechanism with a rolling device comprises a vertical column 1 and a lifting column 2, and further, the cross sections of the vertical column 1 and the lifting column 2 are rectangular. The inner part of the upright post 1 is hollow, the lifting post 2 is arranged in the upright post 1 along the length direction of the upright post 1, a rolling device 5 is arranged in the upright post 1, and the rolling device 5 is contacted with the side wall of the lifting post 2; the vertical column 1 is internally provided with a coil spring 6, one end of the coil spring 6 is fixed on the inner wall of the vertical column 1, and the other end of the coil spring is connected with the lifting column 2. The coil spring 6 can be directly obtained from the market, and the elastic coefficient of the coil spring 6 is 10N/mm-25N/mm.

The screen lifting mechanism with the rolling device comprises a thirty-year-old upright post 1 and a lifting post 2, wherein the lifting post 2 is arranged inside the upright post 1, so that the assembly is convenient; install in the stand 1 rolling device 5, rolling device 5 with 2 lateral walls of lifting column contact, work as lifting column 2 is in during the up-and-down motion in the stand 1, rolling device 5 rolls, be lifting column 2 with the friction between rolling device 5 is rolling friction, and frictional force is little, the lift cooperation is smooth and easy, has improved user's comfort, has great practical value.

More specifically, the top of the lifting column 2 can be used for installing a screen, after the lifting column 2 is installed inside the upright column 1, one end of the coil spring 6 is connected with the lifting column 2, and the other end of the coil spring is fixed on the upright column 1. The lifting column 2 can move up and down freely in the upright column 1. When the lifting column 2 ascends, the coil spring 6 is driven to contract, and the coil spring 6 generates downward pressure to keep the lifting column 2 in a downward trend. After the lifting column 2 is adjusted to be lifted to the required height, the lifting column is fixed, and the screen is at a proper height. When the screen needs to be lowered, the lifting column 2 is released, and the lifting column 2 moves downwards under the pulling of the coil spring 6. It is to be noted that the means for fixing the lifting column 2 may be screws, which are well known in the art and therefore not described in detail. The outer wall of the lifting column 2 in the lifting process is in contact with the rolling device 5 to drive the rolling device 5 to roll, and rolling friction is formed between the lifting column 2 and the rolling device 5. For the polyoxymethylene sliding friction of present crowded material of aluminium and base, frictional force is less, and the cooperation is smooth and easy, consequently user's use comfort is high, installs screen lift on the lift post 2 is also more smooth and easy.

Further, a fixed seat 3 is fixed on the top of the upright post 1, and a through opening 31 for the upright post 1 to pass through is formed in the middle of the fixed seat 3. The fixing base 3 is installed at the top of the upright post 1, on one hand, the rolling device 5 is convenient to install, on the other hand, the lifting post 2 is limited, and the lifting post 2 is prevented from being deviated left and right in the up-down moving process and is straightened to fall off.

Further, the rolling device 5 is installed on the fixed seat 3, as shown in fig. 2, as one embodiment, the rolling device 5 includes an axle core 51 and a roller 52, the axle core 51 is horizontally disposed on the fixed seat 3, and the roller 52 is installed on the axle core 51 and is in rotating fit with the axle core 51. The roller 52 is connected with the shaft core 51 in a rolling manner, and when the lifting column 2 moves up and down, the roller 52 is driven to roll, so that the friction between the lifting column 2 and the roller 52 becomes rolling friction, and the up-and-down movement of the lifting column 2 is smoother. Furthermore, the rolling device 5 comprises a connecting rod and a bearing, the connecting rod is horizontally fixed on the fixed seat 3, and the bearing is installed on the connecting rod. The bearing inner ring and the connecting rod are fixed with each other, and when the lifting column 2 moves up and down, the bearing rotates, so that the friction between the bearing and the lifting column 2 is changed into rolling friction, and the friction force is small.

Further, a spring seat 4 is fixed at the bottom of the lifting column 2, an accommodating cavity is arranged in the spring seat 4, the accommodating cavity is internally provided with the coil spring 6, one end of the coil spring 6 is fixed in the accommodating cavity, and the other end of the coil spring extends out of the accommodating cavity and is fixed on the inner side wall of the upright post 1. The coil spring 6 is fixed in the accommodating cavity, so that the coil spring 6 is prevented from occupying the volume inside the upright post 1, the volume of the whole lifting structure is reduced, and the lifting structure is more convenient to install.

Furthermore, a slotted hole is formed in the middle of the lifting column 2 and penetrates through the lifting column 2 from top to bottom, a boss 41 is arranged at the top of the spring seat 4, and the boss 41 is matched with the slotted hole in shape. Further, the spring seat 4 and the lifting column 2 have hitherto been fixed to each other by screws. The arrangement of the slotted holes saves materials and reduces the weight of the whole lifting mechanism, the left and right movement of the boss 41 is limited by the slotted holes, and the spring seat 4 is fixed on the lifting column 2 by screws to prevent the spring seat 4 from falling.

Furthermore, the top of the fixing seat 3 protrudes outward to form a flange 32, and after the fixing seat 3 is fixed on the upright post 1, the flange 32 abuts against the top of the upright post 1. The flanging 32 is matched with the top of the upright post 1, so that the fixing seat 3 is convenient to install and fix.

Furthermore, a side wall of the upright post 1 is provided with an opening, a side cover 11 is arranged at the opening, and the side cover 11 is connected with the upright post 1 through a screw. The opening is arranged to facilitate installation of relevant parts into the upright post 1, and the side cover 11 facilitates fixing of the coil spring 6 on the side wall of the upright post 1.

Variations and modifications to the above-described embodiments may occur to those skilled in the art, in light of the above teachings and teachings. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention. Furthermore, although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
