DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] See also Figure 1-5 The utility model provides an LED display screen that can be quickly assembled, including a base plate 1 and multiple LED display screen bodies 2, multiple universal self-locking wheels 3 are installed at the bottom of the base plate 1, positioning mechanisms 4 are arranged near the two sides of the top of the base plate 1, two supporting columns 5 are fixedly connected to the top of the base plate 1, multiple cross bars 6 are fixedly connected between the two supporting columns 5, multiple cross bars 6 are rotatably connected to multiple groups of fixing bolts 7 at the rear ends, multiple LED display screen bodies 2 are fixedly connected to back plates 8 at the rear ends, multiple back plates 8 are fixedly connected to connecting columns 9 at the rear ends, multiple connecting columns 9 are fixedly connected to mounting plates 10 at the rear ends, multiple back plates 8 are fixedly connected to connecting mortise grooves 11 on one side, multiple back plates 8 are fixedly connected to connecting tenons 12 on the other sides, multiple back plates 8 are fixedly connected to two plugs 13 on the tops, and multiple back plates 8 have two sockets 14 at the bottoms.

[0024] Further as Figure 4 As shown, it is worth specifically explaining that the positioning mechanism 4 includes a convex frame 401 fixedly connected to the top of the base plate 1, and the inner walls of the front and rear ends of the convex frame 401 are slidably connected with sliders 402, and a partition 403 is fixedly connected between the two sliders 402. A servo motor 404 is installed on the top of the partition 403, and the output end of the servo motor 404 passes through the partition 403 and is fixedly connected with a threaded rod 405, and a fixed suction cup 406 is rotatably installed at the bottom of the threaded rod 405. When the device moves to a specified position, the servo motor 404 is turned on, and the servo motor 404 drives the threaded rod 405 to rotate. While rotating, the threaded rod 405 drives the fixed suction cup 406 to descend and contact with the ground, thereby stably positioning the device.

[0025] Further as Figure 4 As shown, it is worth explaining in detail that the inner walls of the front and rear ends of the convex frame 401 are both provided with limiting grooves corresponding to the slider 402, and the limiting grooves play a role in limiting and guiding the movement of the slider 402, so that the lifting and lowering of the fixed suction cup 406 is more stable.

[0026] Further as Figure 4 As shown, it is worth explaining in detail that a thread groove corresponding to the threaded rod 405 is opened inside the bottom plate 1, and the thread groove and the threaded rod 405 cooperate to ensure that the threaded rod 405 can be lifted and lowered while rotating.

[0027] According to the above working process, it can be known that the universal self-locking wheel 3 and the positioning mechanism 4 are matched, and the universal self-locking wheel 3 allows the device to be easily moved and adjusted in position, especially when the position of the display screen needs to be frequently changed or fine-tuned, the operation can be completed quickly and accurately, and the positioning mechanism 4 can ensure that the display screen is stably fixed after the position is set, reduce unnecessary movement and shaking, and avoid the device from tipping over and being damaged.

[0028] Further as Figure 1 and Figure 4 As shown, it is worth mentioning that a protective film is attached to the front end of the plurality of LED display screen bodies 2. The protective film can effectively protect the front end of the LED display screen body 2 and the lamp beads from external physical damage, such as touch, scratch, impact, etc., which helps to extend the service life of the LED lamp beads and reduce the maintenance and replacement costs caused by mechanical damage. At the same time, the protective film has the characteristics of anti-reflection and contrast enhancement, which can improve the visual effect of the display screen and make the image and text clearer and easier to read. The protective film has dustproof and waterproof functions, which can effectively prevent dust, moisture and other particulate matter from entering the interior of the display screen, which is especially important for outdoor display screens and can keep the screen clear and in a stable working state.

[0029] Further as Figure 2 and Figure 3As shown, it is worth specifically explaining that the rear ends of the plurality of mounting plates 10 are provided with mounting holes corresponding to the fixing bolts 7 to ensure that the mounting holes and the fixing bolts 7 are matched, so as to facilitate the installation and disassembly of the back plate 8 and the LED display screen body 2.

[0030] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that the outer wall of the connecting tenon 12 fits tightly with the inner wall of the connecting tenon groove 11, and the connecting tenon groove 11 cooperates with the connecting tenon 12, so that multiple LED display screen bodies 2 in the horizontal direction can be connected into a whole, and the outer wall of the plug 13 fits tightly with the inner wall of the socket 14, connecting multiple LED display screen bodies 2 in the vertical direction into a whole.

[0031] This solution has the following working process: in actual use, when splicing in the horizontal direction, align the connecting tenon 12 with the inner wall of the connecting tenon groove 11 and insert it; when splicing in the vertical direction, insert the plug 13 into the inner wall of the socket 14, assemble multiple LED display screen bodies 2 into a whole, and then install the back panel 8 and the LED display screen body 2 at the front end of the cross bar 6 through the fixing bolts 7; move the device to the specified position through multiple universal self-locking wheels 3, and then turn on the servo motor 404, the servo motor 404 drives the threaded rod 405 to rotate, and the threaded rod 405 drives the fixed suction cup 406 to descend and contact with the ground while rotating, so as to stably position the device.

[0032] In summary: the universal self-locking wheel 3 and the positioning mechanism 4 are matched, and the universal self-locking wheel 3 allows the device to be easily moved and adjusted in position, especially when the display screen position needs to be frequently changed or fine-tuned, the operation can be completed quickly and accurately, and the positioning mechanism 4 can ensure that the display screen is stably fixed after the position is set, reduce unnecessary movement and shaking, and avoid the equipment from tipping over and being damaged; by setting the connecting groove 11 and the connecting tenon 12 to match, multiple LED display screen bodies 2 in the horizontal direction can be connected into a whole, and by setting the plug 13 and the socket 14 to match, multiple LED display screen bodies 2 in the vertical direction are connected into a whole, so that the multiple LED display screen bodies 2 are firmly connected to each other, which is convenient for the splicing and disassembly of the display screen and increases the stability of the device.
