DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-8 A stepless lifting structure of a TV stand includes a support column 1, which is composed of a column tube 101 and a telescopic column 102. A tripod support rod 2 is fixedly connected to the bottom of the support column 1. The tripod support rod 2 is a three-leg structure, and the position distribution angle of the three legs is 120 degrees, so as to stably support the support column 1. An adjustment structure 3 is arranged on the outside of the support column 1, and a lifting component 4 is arranged on the inside of the column tube 101.

[0027] The adjustment structure 3 includes a fixing seat 301 coaxially fixed to the outer side of the support column 1, an aluminum alloy gear control component 302 is arranged on the back side of the fixing seat 301, and a first anti-slip component 303 is fixedly connected to the inner side of the aluminum alloy gear control component 302, and the first anti-slip component 303 can increase the friction force when the adjustment plate 3022 and the gear plate 3021 are engaged, and an angle control component 304 is arranged on the outside of the aluminum alloy gear control component 302, and a second anti-slip component 305 is fixedly connected to the inner side of the fixing seat 301, and the second anti-slip component 305 can increase the friction force between the fixing seat 301 and the support column 1, thereby increasing the load-bearing capacity when the TV is installed.

[0028] The lifting assembly 4 includes a threaded column 401 rotatably connected to the inside of the column tube 101, a worm wheel 402 is coaxially fixed to the outside of the bottom of the threaded column 401, and a worm 403 is rotatably connected to the inside of the adjusting block. By rotating the worm 403 and engaging the worm 403 to drive the worm wheel 402, the threaded column 401 rotates synchronously and drives the telescopic column 102 to rise through the slip ring to adjust the installation height.

[0029] When implementing, follow these steps:

[0030] 1) First, the adjustment plate 3022 is connected to the card strip on the shift plate 3021 through the card slots at different positions, and different installation height gears are adjusted, and the adjustment plate 3022 and the shift plate 3021 are fixed by bolt rods;

[0031] 2) Then fix the back of the TV structure to the back of the adjustment plate 3022 through a bolt structure to complete the TV installation;

[0032] 3) Rotate the adjustment rod 3041 again, and use the adjustment rod 3041 to drive the shift plate 3021 so that the TV can be adjusted to the left or right installation angle;

[0033] 4) Finally, by rotating the adjusting screw, the limit ring 3043 is meshed and connected with the gear 3042 structure to limit and fix the installation angle.

[0034] according to Figure 2 As shown, the support column 1 includes a column barrel 101 and a telescopic column 102 structure. The threaded column 401 is rotated by rotating the worm 403 structure in the adjustment block on the left side of the column barrel 101 and utilizing the worm 403 to engage with the worm wheel 402 structure on the outer side of the bottom of the threaded column 401. Since both the telescopic column 102 and the column barrel 101 are provided with hollow grooves of cylindrical structures, and a slip ring is fixed to the inner bottom of the telescopic column 102, the slip ring is threadedly connected to the threaded column 401.

[0035] according to Figure 2As shown, the threaded column 401 is used to drive the slip ring to move up and down, so that the telescopic column 102 can move up and down synchronously to adjust the installation height. The tripod support rod 2 is a three-leg structure, and the position distribution angle of the three legs is 120 degrees, which can provide stable support for the column tube 101 and the upper structure.

[0036] according to Figure 4 and Figure 5 As shown, the aluminum alloy gear control component 302 includes a gear plate 3021 and two adjustment plates 3022, both of which are made of solid aluminum alloy material. The card slot structure on the front of the adjustment plate 3022 is adapted to the card strips at the top and bottom of the gear plate 3021 to facilitate the card connection of the adjustment plate 3022 to the gear plate 3021. At the same time, the installation gear height can be adjusted according to the card slots at different positions. The solid aluminum alloy material has a strong ability to resist fracture and damage, so that the aluminum alloy gear control component 302 can effectively bear a weight of more than 100 kilograms, which is far more than 5 times the weight of the TV.

[0037] according to Figure 5 and Figure 6 as well as Figure 7 As shown, the adjustment plate 3022 is clamped with the first anti-slip part 303 on the inner top wall and the inner bottom wall of the shift plate 3021 through a clamping groove. The first anti-slip part 303 is made of POM engineering plastic anti-slip material, which can increase the friction between the adjustment plate 3022 and the shift plate 3021 when clamped, making the clamping structure more stable, and the adjustment plate 3022 and the shift plate 3021 are further fixed by inserting the bolt rod through the threaded hole structure on the back of the adjustment plate 3022. The second anti-slip part 305 is also made of POM engineering plastic anti-slip material, which can increase the friction between the fixing base 301 and the support column 1, thereby increasing the load-bearing capacity when the TV is installed.

[0038] according to Figure 5 and Figure 6 as well as Figure 7 As shown, first rotate the adjusting screw to disengage the limit ring 3043 from the gear 3042 structure on the outer side of the top of the adjusting rod 3041, and then rotate the adjusting rod 3041 to drive the shift plate 3021 to rotate, so as to adjust the left and right angles of the TV when it is installed. After the angle adjustment is completed, rotate the adjusting screw again to re-engage the inner tooth layer of the limit ring 3043 with the gear 3042, thereby limiting and fixing the installation angle.

[0039] The adjusting screw rod 3043 is rotated to engage with the gear 3042 structure of the adjusting rod 3041 to limit and fix the left and right angles of the TV when the TV is installed, thereby solving the problem that the liftable TV bracket in the above-mentioned background technology cannot adjust the angles of the support member and the support plate, and cannot meet the left and right adjustment requirements when the TV is installed.
