[0002] A display screen, also known as an electronic display screen or a mobile display screen, is composed of an LED dot matrix. It displays text, images, animations, and videos by turning red, blue, yellow, white, and green LEDs on and off. Outdoor advertising display screens are a type of display screen used to play advertisements.

[0003] Patent CN207471078U discloses an LED display screen for advertising, including a bracket, a mounting back plate, a rear housing, a front housing, an LED display screen, and a display screen holder. The mounting back plate is connected to the upper surface of the bracket, and the rear housing is connected to the front surface of the mounting back plate. The mounting back plate is movably mounted on the bracket. The display screen is mounted on the display screen holder, and casters are fixedly connected to the bottom of the bracket. Although the above patent allows for height adjustment of the display screen by setting a telescopic rod, it cannot fix the rotation angle of the rear casters when pushing the bracket, which can easily lead to the rear casters rotating arbitrarily, increasing the difficulty of pushing.

[0004] Therefore, there is a particular need for an ultra-high-definition COB display that can fix the rotation angle of the rear casters in order to solve the problems existing in the prior art. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents that cannot fix the rotation angle of the rear casters when pushing the bracket, which easily leads to the rear casters rotating randomly and increasing the difficulty of pushing, this utility model provides an ultra-high-definition COB display screen that can fix the rotation angle of the rear casters.

[0006] This utility model is achieved through the following technical means: an ultra-high-definition COB display screen, including a base, a bracket, a telescopic plate, a pressure plate, elastic elements, sliders, a display screen body, and casters. The bracket is fixedly connected to the base, and the telescopic plate is slidably arranged inside the bracket. The pressure plate is fixedly connected to the telescopic plate, and multiple elastic elements are connected to the telescopic plate and the bracket. Two grooves are opened on the base, and two sliders are slidably arranged inside the grooves. The display screen body is rotatably arranged on the two sliders. The pressure plate is in contact with the display screen body. Multiple casters are installed at the bottom of the base. It also includes a support plate, a control rod, a limit block, a rope, and a handle. Two support plates are installed on the base, and the control rod is slidably arranged on the two support plates. Two limit blocks for positioning are fixedly connected to the casters. The control rod and the limit blocks are connected to a rope, and a handle is fixedly connected to the control rod.

[0007] Furthermore, it also includes a fixing frame, a first motor, a winding wheel, and a winding rope. The fixing frame is mounted on the base, and the first motor is mounted on the fixing frame. A winding wheel for winding the winding rope is fixed to the output shaft of the first motor. The winding rope is wound on the winding wheel, and one end of the winding rope is connected to the display screen body.

[0008] Furthermore, it also includes a second motor, a screw, a guide rod, a moving plate, and a wiping block. The second motor is installed on the display screen body, and a screw is set on the output shaft of the second motor through a coupling. A guide rod is fixed to the display screen body, and a moving plate is threaded on the screw. A wiping block for wiping the surface of the display screen body is embedded in the moving plate, and the wiping block is in contact with the display screen body.

[0012] Based on the above description of the structure of this utility model, the design starting point, concept, and advantages of this utility model are as follows:

[0013] 1. By moving the control lever left and right to the appropriate position, the rope pulls the limit block to position the rear caster at the appropriate angle, thereby fixing the rotation angle of the rear caster and preventing it from rotating randomly, which would increase the difficulty of pushing.

[0014] 2. By turning on the first motor, the output shaft of the first motor rotates, driving the winding wheel to rotate and wind the winding rope. This causes the winding rope to pull the display screen body to rotate backward to a suitable angle, thereby achieving the purpose of automatically adjusting the display screen body's playback angle so that pedestrians can better view the display screen body.

[0015] 3. By turning on the second motor, the output shaft of the second motor rotates, which drives the screw to rotate, thereby causing the moving plate to move the wiping block downward to wipe the surface of the display screen body, so as to avoid excessive dust and other impurities from adhering to the surface of the display screen body and affecting the playback effect.

Detailed Implementation

[0021] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Example 1: An ultra-high-definition COB display screen, see [link / reference] Figures 1-4 As shown, the device includes a base 1, a bracket 101, a telescopic plate 103, a pressure plate 102, elastic elements 104, sliders 11, a display screen body 2, and casters 3. The bracket 101 is welded onto the base 1. The telescopic plate 103 slides inside the bracket 101. The pressure plate 102 is welded onto the telescopic plate 103. Multiple elastic elements 104 are connected to both the telescopic plate 103 and the bracket 101. Two grooves 12 are formed on the base 1. Two sliders 11 slide inside the grooves 12. The display screen body 2 is rotatably mounted on both sliders 11. The pressure plate 102 contacts the display screen body 2. The base 1 has multiple casters 3 bolted to its bottom, which are distributed on the left and right sides of the bottom. It also includes a support plate 8, a control rod 7, a limit block 5, a rope 6, and a handle 9. The base 1 has two support plates 8 bolted to its bottom, and the control rod 7 is slidably mounted on both support plates 8. The casters 3 have two limit blocks 5 welded to them for positioning. The control rod 7 and the limit blocks 5 are connected to the rope 6. The control rod 7 has a handle 9 welded to it, which increases the contact area between the operator's hand and the control rod 7, making it easier to move the control rod 7.

[0023] See Figure 1 As shown, it also includes a rain cover 17. The rain cover 17 is installed on the display body 2 by means of bolts to protect it from rain. The rain cover 17 is made of rainproof material to prevent rainwater from dripping onto the display body 2 through the rain cover 17.

[0024] See Figure 1 and Figure 2 As shown, it also includes a rubber sleeve 18. The handle 9 is covered with a rubber sleeve 18 for anti-slip purposes. The rubber sleeve 18 is made of rubber, which has adhesive properties and can achieve a good anti-slip effect.

[0025] When the advertising display screen needs to be used, the staff member holds the handle 9 and pushes the base 1. The rubber sleeve 18 increases the friction between the staff member's hand and the handle 9 to prevent the staff member's hand from slipping. When pushing the base 1, the universal wheel 3 rotates to reduce the friction between the base 1 and the ground, making it easier for the staff member to push the base 1. The staff member moves the control lever 7 left and right to the appropriate position, so that the rope 6 pulls the limit block 5 to make the universal wheel 3 on the rear side at the appropriate angle, thereby achieving the purpose of fixing the rotation angle of the universal wheel 3 on the rear side and preventing the universal wheel 3 from rotating randomly and increasing the difficulty of pushing. After pushing the base 1 to the appropriate position, the staff member turns on the display screen body 2 and makes the display screen body 2 start playing advertisements for pedestrians to watch. In rainy weather, the rain cover 17 protects the display screen body 2 from rain and prevents rainwater from dripping onto the display screen body 2.

[0026] Example 2: Based on Example 1, refer to Figure 1 and Figure 4 As shown, it also includes a fixing frame 10, a first motor 1001, a winding wheel 1002, and a winding rope 1003. The fixing frame 10 is bolted to the base 1, and the first motor 1001 is bolted to the fixing frame 10. The winding wheel 1002 for winding the winding rope 1003 is welded to the output shaft of the first motor 1001. The winding rope 1003 is wound on the winding wheel 1002, and one end of the winding rope 1003 is connected to the display screen body 2.

[0027] See Figure 1 and Figure 4 As shown, it also includes an anti-slip pad 19, which is embedded in the base 1 to increase friction.

[0028] When the display screen 2 is turned on to play an advertisement, the staff turns on the first motor 1001. The output shaft of the first motor 1001 rotates, driving the winding wheel 1002 to rotate and wind the winding rope 1003. This causes the winding rope 1003 to pull the display screen 2 to rotate backward, causing the display screen 2 to press the pressure plate 102 and the telescopic plate 103 to move backward. The elastic element 104 is compressed accordingly, and the anti-slip pad 19 increases the friction between the display screen 2 and the base 1, allowing the display screen 2 to rotate smoothly backward. When the display screen 2 rotates to a suitable angle, the staff turns off the first motor 1001, thereby achieving the purpose of automatically adjusting the playback angle of the display screen 2, so that pedestrians can better view the display screen 2. The pressure plate 102 supports the display screen 2 and prevents the display screen 2 from rotating backward.

[0029] See Figure 1 and Figure 4 As shown, it also includes a second motor 13, a screw 14, a guide rod 15, a moving plate 16, and a wiping block 1601. The second motor 13 is bolted to the display body 2. The output shaft of the second motor 13 is connected to the screw 14 via a coupling. The guide rod 15 is welded to the display body 2. The moving plate 16 is threaded onto the screw 14. The wiping block 1601 for wiping the surface of the display body 2 is embedded in the moving plate 16. The wiping block 1601 is in contact with the display body 2 and is made of a soft material to avoid scratching the surface of the display body 2.

[0030] When an advertisement is playing on the display screen 2, dust and other impurities from the outside world will adhere to the surface of the display screen 2. The staff will turn on the second motor 13. The output shaft of the second motor 13 will rotate, which will drive the screw 14 to rotate, thereby causing the moving plate 16 to move the wiping block 1601 downward to wipe the surface of the display screen 2, so as to avoid too much dust and other impurities from adhering to the surface of the display screen 2 and affecting the playback effect. After wiping is completed, the staff will turn off the second motor 13.

[0031] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
