[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-5 As shown, this utility model provides a universal angle-adjustable display rack, including a base 1. The upper surface of the base 1 has a rectangular array of slots 7. A weight-adding block 6 is fixedly installed on the inner wall of the slot 7. The weight-adding block 6 can increase the weight of the base 1, thereby improving the overall stability of the display rack. A housing 8 is fixedly connected to the upper surface of the base 1. A support rod 9 is slidably connected inside the housing 8. The damped sliding connection between the housing 8 and the support rod 9 allows the support rod 9 to move smoothly up and down within the housing 8, facilitating the adjustment of the display rack's height. A positioning mechanism 3 is provided between the housing 8 and the support rod 9. The positioning mechanism 3 can position the support rod 9 after it is adjusted to a suitable height, preventing the support rod 9 from automatically slipping down and ensuring the stability of the display rack structure.

[0021] Above the support rod 9 is a display panel body 5, which is a magnetic plate. Multiple magnetic blocks 4 are magnetically connected to one side of the display panel body 5. The display panel body 5 is designed as a magnetic plate and works with the magnetic blocks 4 to facilitate users to attach the posters to the display panel body 5 using the magnetic blocks 4. Installation and disassembly are convenient and quick. An angle adjustment mechanism 2 is provided between the display panel body 5 and the support rod 9, which allows the display panel body 5 to be adjusted to multiple angles to meet the display needs of different angles and improve the practicality of the display rack.

[0022] The angle adjustment mechanism 2 includes a first DC motor 23, which is fixedly installed inside the support rod 9. The output end of the first DC motor 23 passes through the support rod 9 and is fixedly connected to a support plate 22. The lower surface of the support plate 22 is rotatably connected to the upper surface of the support rod 9. The first DC motor 23 drives the support plate 22 to rotate, which in turn drives the display panel body 5 connected to the support plate 22 to rotate, thereby realizing the angle adjustment of the display panel body 5 in the horizontal direction.

[0023] A guide frame 26 is fixedly connected to the upper surface of the support plate 22. A second DC motor 202 is fixedly installed on one side of the guide frame 26. A support platform 201 for use with the second DC motor 202 is fixedly connected to one side of the guide frame 26. The second DC motor 202 is fixedly installed on the upper surface of the support platform 201. The support platform 201 provides a stable installation position for the second DC motor 202. The output end of the second DC motor 202 passes through the guide frame 26 and is fixedly connected to a screw 27. The second DC motor 202 drives the screw. The screw 27 rotates, and one end of the screw 27 facing away from the output end of the second DC motor 202 is rotatably connected to the inner cavity of the guide frame 26. The guide frame 26 ensures the stable rotation of the screw 27. The outer surface of the screw 27 is threaded with a slider 29. When the screw 27 rotates, it drives the slider 29 to move along the axial direction of the screw 27 within the guide frame 26. Horizontal plates 28 are symmetrically fixedly connected to both sides of the slider 29. The slider 29 is slidably connected to the guide frame 26. The lower surface of the horizontal plate 28 is slidably connected to the support plate 22. The movement of the slider 29 drives the horizontal plate 28 to move.

[0024] A first hinge 203 is fixedly connected to the upper surface of the horizontal plate 28, and a second hinge 25 is fixedly connected to one side of the display panel body 5 in parallel. Correspondingly, a connecting rod 24 is rotatably connected between the first hinge 203 and the second hinge 25. A hinge rod 21 is fixedly connected to one side of the display panel body 5, and the hinge rod 21 is rotatably connected to the support plate 22 through a rotating shaft. When the slider 29 and the horizontal plate 28 move, the first hinge 203 and the second hinge 25 connected by the connecting rod 24 drive the display panel body 5 to rotate around the rotating shaft of the hinge rod 21 and the support plate 22, thereby realizing the tilt angle adjustment of the display panel body 5 in the vertical direction, improving the angle adjustment range of the display panel body 5, and meeting different display needs.

[0025] The positioning mechanism 3 includes a first positioning groove 33, which is located on one side of the support rod 9. The housing 8 has a second positioning groove 31, which is equally spaced on one side and works in conjunction with the first positioning groove 33. The inner cavities of the first positioning groove 33 and the second positioning groove 31 are fitted with a positioning rod 32 for damping. When the height of the support rod 9 needs to be adjusted, the positioning rod 32 is pulled out. After adjusting to a suitable height, the positioning rod 32 is inserted into the corresponding first positioning groove 33 and the second positioning groove 31 to position the support rod 9. The operation is simple and convenient, effectively preventing the support rod 9 from slipping off automatically and ensuring the stability of the display rack structure.

[0026] Working principle: When the height of the display rack needs to be adjusted, the positioning mechanism 3 is used first. The positioning rod 32 in the positioning mechanism 3 is originally damped and inserted into the corresponding first positioning groove 33 and second positioning groove 31. The positioning rod 32 is pulled out, and the support rod 9 can slide damped within the housing 8. After adjusting to the appropriate height, the positioning rod 32 is inserted into the corresponding first positioning groove 33 and second positioning groove 31 to lock the height of the support rod 9, prevent the support rod 9 from slipping down automatically, and ensure the stability of the display rack height.

[0027] When it is necessary to adjust the horizontal angle of the display panel body 5, the first DC motor 23 in the angle adjustment mechanism 2 is activated. The output end of the first DC motor 23 drives the support plate 22 to rotate around the connection point with the support rod 9, thereby driving the display panel body 5 installed on the support plate 22 to adjust the angle in the horizontal direction to meet different display needs.

[0028] When the vertical angle of the display panel body 5 needs to be adjusted, the second DC motor 202 in the angle adjustment mechanism 2 is activated. The output end of the second DC motor 202 drives the screw 27 to rotate. When the screw 27 rotates, the slider 29 moves linearly along the guide frame 26. At the same time, the lower surface of the horizontal plate 28, which is symmetrically fixed on both sides of the slider 29, is slidably connected to the support plate 22 to ensure the stability of the movement of the horizontal plate 28.

[0029] The first hinge seat 203 on the upper surface of the horizontal plate 28 is rotatably connected to the second hinge seat 25 on one side of the display plate body 5 via the connecting rod 24. A hinge rod 21 is also fixedly connected to one side of the display plate body 5. The hinge rod 21 is rotatably connected to the support plate 22 via a rotating shaft. As the horizontal plate 28 moves stably, the connecting rod 24 drives the display plate body 5 to rotate around the rotating shaft of the hinge rod 21 and the support plate 22, thereby realizing the tilt angle adjustment of the display plate body 5 in the vertical direction. The coordinated action of the first DC motor 23 and the second DC motor 202 realizes the multi-angle adjustment of the display rack.

[0030] When displaying posters, the posters are fixed to one side of the display board body 5 by magnetic blocks 4, making it convenient and quick to display the posters. At the same time, the weight-adding blocks 6 increase the weight of the base 1, lower the center of gravity of the display rack, and enhance the overall stability of the display rack during use.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
