[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods:

[0024] like Figure 1-6As shown, the utility model provides a mobile bracket for an LCD TV, comprising a base 1 and a bracket 2, wherein the inner wall of the base 1 is provided with a mounting groove, the bracket 2 slides in cooperation with the mounting groove, and one end thereof abuts against the inner wall of the mounting groove, a limiting component 3 and a positioning component 5 are arranged between the base 1 and the bracket 2, the limiting component 3 comprises two limiting rods 303, the outer wall of the limiting rod 303 is provided with a slot 304, two slides 305 are fixedly mounted on the inner wall of the base 1, a return spring 306 is arranged on the inner wall of the slide 305, the positioning component 5 comprises a bidirectional screw rod 501 and two positioning blocks 502, the bidirectional screw rod 501 can drive the two positioning blocks 502 to move toward each other, the slot 304 can squeeze the return spring 306 when sliding in the slide 305, a transmission component 4 is arranged in the mounting groove, the transmission component 4 comprises a rotating rod 402, and the rotating rod 402 drives the bidirectional screw rod 501 to move toward each other, Rotate towards the screw rod 501, a number of moving wheels 100 are provided at the bottom of the base 1, a number of dust covers 101 are provided on the sliding sleeve of the outer wall of the base 1, a number of positioning holes of different shapes are opened on the outer wall of the bracket 2, the positioning block 502 and the slot 304 slide in cooperation with the positioning holes of different shapes, the limiting assembly 3 also includes a connecting plate 301 and a handle 302, the limiting rod 303 slides in cooperation with the base 1, the connecting plate 301 is fixedly mounted on one end of the two limiting rods 303, the handle 302 is fixedly mounted on one end of the connecting plate 301, the positioning assembly 5 also includes two guide blocks 503 and a slide rail 504, the slide rail 504 is fixedly mounted on the bottom end of the inner wall of the mounting groove, the two guide blocks 503 are both slidably matched with the slide rail 504, and are respectively fixedly connected to the bottom of the two positioning blocks 502, and the two positioning blocks 502 are both threadedly sleeved on the bidirectional screw rod 501.

[0025] When the bracket 2 and the base 1 need to be disassembled, the two-way screw rod 501 is rotated. When the two-way screw rod 501 rotates, it is threadedly engaged with the two positioning blocks 502. The positioning blocks 502 move toward each other under the limit of the slide rail 504 and the guide block 503, thereby allowing the two positioning blocks 502 to disengage from the slots 304 and the positioning holes. At this time, the two limiting rods 303 are no longer limited by the positioning blocks 502, and the return spring 306 releases the pressure, which can push the limiting rod 303 to move horizontally, thereby causing the handle 302 and the connecting plate 301 to move a certain distance, making it convenient for the staff to take out the entire limiting assembly 3. At the same time, the bracket 2 is no longer fixed, and the bracket 2 can be directly taken out from the base 1. There is no need for the operator to repeatedly install individual parts, which reduces the operation steps and time, and further improves work efficiency.

[0026] Bracket 2 is prior art and will not be explained here.

[0027] like Figure 5-6As shown, in one embodiment, the transmission assembly 4 also includes a fixing member 406, which is fixedly installed on the top of the inner wall of the mounting groove, and the bidirectional screw rod 501 is rotatably connected to the fixing member 406. One end of the fixing member 406 is rotatably connected to the rotating shaft 405. The outer walls of the rotating shaft 405 and the bidirectional screw rod 501 are fixedly installed with pulleys 407. Belts 408 are sleeved on the two pulleys 407. The rotating rod 402 is rotatably connected to the base 1. The two ends of the rotating rod 402 are respectively fixedly installed with a turning handle 401 and a driving bevel gear 403. The outer wall of the rotating shaft 405 is fixedly installed with a driven bevel gear 404, and the driving bevel gear 403 is meshed with the driven bevel gear 404.

[0028] The rotating rod 402 is rotated by turning the handle 401, and the rotating rod 402 drives the driving bevel gear 403 to rotate. When the driving bevel gear 403 rotates, it engages with the driven bevel gear 404 and drives the driven bevel gear 404 and the rotating shaft 405 to rotate. After the rotating shaft 405 rotates, the two-way screw rod 501 is driven to rotate through two pulleys 407 and belt 408. The bracket 2 is unlocked by rotating the rotating rod 402 sideways, and the disassembly time will not be increased due to the impact of the equipment volume. The installation and disassembly efficiency is fast and the applicability is strong.

[0029] The following is a detailed description of the working principle of the LCD TV mobile bracket:

[0030] When the bracket 2 and the base 1 need to be disassembled, the rotating rod 402 is rotated by turning the handle 401. After the rotating rod 402 rotates, the driving bevel gear 403 is driven to rotate. When the driving bevel gear 403 rotates, it meshes with the driven bevel gear 404 and drives the driven bevel gear 404 and the rotating shaft 405 to rotate. After the rotating shaft 405 rotates, the two-way screw rod 501 is driven to rotate through two pulleys 407 and belt 408. When the two-way screw rod 501 rotates, it is threadedly engaged with the two positioning blocks 502. The positioning blocks 502 move toward each other under the limit of the slide rail 504 and the guide block 503, thereby making the two positioning blocks 502 The two limiting rods 303 are no longer limited by the positioning block 502, and the return spring 306 releases the pressure, which can push the limiting rod 303 to move horizontally, thereby causing the handle 302 and the connecting plate 301 to move a certain distance, making it easier for the staff to remove the entire limiting assembly 3. At the same time, the bracket 2 is no longer fixed and can be directly removed from the base 1. The operation method is simple. The bracket 2 is unlocked by rotating the rotating rod 402 sideways. The disassembly time will not be affected by the size of the equipment and will not increase. The installation efficiency is fast and the applicability is strong:

[0031] At the same time, the bidirectional screw 501 can drive the two positioning blocks 502 to move in opposite directions when reversing, so that the two positioning blocks 502 can quickly position the bracket 2 and the limit rod 303, eliminating the need for operators to repeatedly install individual parts, reducing operation steps and time, and further improving work efficiency.

[0032] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
