Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, in particular to a foldable LED display screen. Background Technique

[0002] LED is a light-emitting diode. An LED display screen is a flat panel display composed of small LED module panels, which is a device for displaying various information such as text, images, videos, and video signals.

[0003] The application number is 202021779080.2, and the patent name is a foldable LED display screen structure. By pulling the square rod, the square rod is disengaged from the pin hole, and the limit fixation of the square rod on the second L-shaped clamping plate is released. The right display screen is rotated so that the right display screen rotates towards the left display screen with the fixed axis as the center, thereby folding the right display screen to the front of the left display screen, reducing the space occupied by the display screen, improving the convenience of transporting the display screen and the transportation cost, and effectively improving the convenience of carrying and handling the display screen.

[0004] However, there are still deficiencies: Although the occupied space of the display screen is reduced by folding the right display screen, during work, since the left and right display screens cannot be completely attached to each other, there is a sense of deficiency between the display screens, affecting the viewing effect of the display screen. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a foldable LED display screen, which effectively solves the problem that the display screens cannot be completely attached to each other in the prior art, resulting in a sense of deficiency between the display screens and affecting the viewing effect of the display screens.

[0006] To solve the above problems, the technical solutions adopted by the utility model are as follows:

[0007] A foldable LED display screen includes a base. Both sides of one end of the base are respectively rotatably connected with a first display screen and a second display screen. A third display screen slidably connected to the base is arranged between the first display screen and the second display screen. A folding structure is arranged on the base. The folding structure includes a first support rod and a second support rod slidably connected to the base. One end of the first support rod is rotatably connected to the first display screen, and one end of the second support rod is rotatably connected to the second display screen. First support turntables and second support turntables rotatably connected to the base are respectively arranged at the proximal ends of the first display screen and the second display screen. The first support turntable and the second support turntable are drivingly connected to the third display screen.

[0008] The folding structure includes a limiting frame fixedly connected to the base. A sliding plate is slidably connected to the limiting frame. The two ends of the sliding plate are respectively rotatably connected to a first support rod and a second support rod. A slider is fixedly connected to the upper end of the sliding plate. A screw rod threadedly connected to the slider is rotatably connected to the limiting frame.

[0009] Semicircular gears are respectively fixedly connected to the facing surfaces of the first support turntable and the second support turntable. A sliding support block is fixedly connected to the lower end of the third display screen. Rack teeth meshing with the semicircular gears are respectively arranged at the two ends of the sliding support block. A sliding pin slidably connected to the inner wall of the base is fixedly connected to the bottom of the sliding support block.

[0010] The thicknesses of the first display screen and the second display screen are greater than that of the third display screen.

[0011] The structure of the present utility model is novel, ingeniously conceived, and simple and convenient to operate. Compared with the prior art, it has the following advantages:

[0012] By arranging the folding structure in the present utility model, when the first support rod and the second support rod slide along the base, they swing towards each other. The first support rod and the second support rod respectively drive the first display screen and the second display screen to deflect and fold around the first support turntable and the second support turntable, reducing the space occupied by the display screens, improving the convenience of transporting the display screens and the transportation cost, and effectively improving the convenience of carrying and transporting the display screens.

[0013] The sliding support block drives the third display screen to slide outwards, and the sliding direction is opposite to the deflection direction of the first display screen and the second display screen. On the one hand, by arranging the third display screen, the third display screen can make up for the gap between the first display screen and the second display screen, avoiding a sense of deficiency between the first display screen and the second display screen. On the other hand, since the first display screen and the second display screen in the prior art are usually arranged in a fitting manner, the first display screen and the second display screen cannot be driven to rotate and fold when they are in contact. Therefore, when the first display screen and the second display screen in this application are driven to rotate and fold, the third display screen moves outwards, which can ensure that the first display screen and the second display screen can be normally driven to rotate and fold.

[0019] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] As Figures 1-4 shown, a foldable LED display screen includes a base 5. Both sides of one end of the base 5 are respectively rotatably connected with a first display screen 1 and a second display screen 2. A third display screen 4 slidably connected to the base 5 is arranged between the first display screen 1 and the second display screen 2. A folding structure is arranged on the base 5. The folding structure includes a first supporting rod 9 and a second supporting rod 11 slidably connected to the base 5. One end of the first supporting rod 9 is rotatably connected to the first display screen 1, and one end of the second supporting rod 11 is rotatably connected to the second display screen 2. First supporting turntables 13 and second supporting turntables 18 rotatably connected to the base 5 are respectively arranged at the adjacent ends of the first display screen 1 and the second display screen 2. The first supporting turntables 13 and the second supporting turntables 18 are drivingly connected to the third display screen 4.

[0021] When the present invention is in use, frames 3 are arranged on the first display screen 1 and the second display screen 2. The frames 3 play a role in supporting the first display screen 1 and the second display screen 2. The first supporting turntables 13 and the second supporting turntables 18 are fixedly arranged on the frames at the lower ends of the first display screen 1 and the second display screen 2. When it is necessary to fold the first display screen 1 and the second display screen 2, control the folding structure to work. When the first supporting rod 9 and the second supporting rod 11 slide along the base 5, they swing towards each other. The first supporting rod 9 and the second supporting rod 11 respectively drive the first display screen 1 and the second display screen 2 to deflect and fold with the first supporting turntables 13 and the second supporting turntables 18 as axes, reducing the space occupied by the display screen, improving the convenience of transporting the display screen and the transportation cost, and effectively improving the convenience of carrying and transporting the display screen. At the same time, the third display screen 4 moves outwards when the first display screen 1 and the second display screen 2 deflect. The sliding direction of the third display screen 4 is opposite to the deflection direction of the first display screen 1 and the second display screen 2, avoiding interference and limiting of the deflection of the first display screen 1 and the second display screen 2 by the third display screen 4. The third display screen 4 can make up for the gap between the first display screen 1 and the second display screen 2, avoiding a sense of deficiency between the first display screen 1 and the second display screen 2.

[0022] The folding structure includes a limit frame 8 fixedly connected to the base 5. A sliding plate 12 is slidably connected to the limit frame 8. The two ends of the sliding plate 12 are respectively rotatably connected to a first support rod 9 and a second support rod 11. A slider 10 is fixedly connected to the upper end of the sliding plate 12. A screw rod 7 threadedly connected to the slider 10 is rotatably connected to the limit frame 8.

[0023] As Figure 1 shown, a rotating handle 6 is provided at one end of the screw rod 7. By driving the screw rod 7 to rotate through the rotating handle 6, during the rotation of the screw rod 7, through the threaded cooperation with the slider 10, the slider 10 is driven to slide along the axial direction of the screw rod 7. The slider 10 drives the lower sliding plate 12 to slide along the upper end surface of the limit frame 8. The two ends of the sliding plate 12 respectively drive the first support rod 9 and the second support rod 11 to deflect towards each other. The first support rod 9 and the second support rod 11 respectively drive the first display screen 1 and the second display screen 2 to deflect towards each other with the first support turntable 13 and the second support turntable 18 as axes, thereby folding the first display screen 1 and the second display screen 2.

[0024] Semicircular gears 17 are respectively fixedly connected to the facing surfaces of the first support turntable 13 and the second support turntable 18. A sliding support block 15 is fixedly connected to the lower end of the third display screen 4. Rack bars 16 meshing with the semicircular gears 17 are respectively provided at the two ends of the sliding support block 15. A sliding pin 14 slidably connected to the inner wall of the base 5 is fixedly connected to the bottom of the sliding support block 15.

[0025] As Figure 3 and 4 shown, when the first support turntable 13 and the second support turntable 18 are driven to rotate along with the first display screen 1 and the second display screen 2, the first support turntable 13 and the second support turntable 18 respectively drive the semicircular gears 17 to rotate. When the semicircular gears 17 rotate, they drive the sliding support block 15 at the lower end of the rack bar 16 to slide outwards under the limitation of the sliding pin 14. The sliding support block 15 drives the third display screen 4 to slide outwards, and the sliding direction is opposite to the deflection direction of the first display screen 1 and the second display screen 2. On the one hand, the third display screen 4 can make up for the gap between the first display screen 1 and the second display screen 2, avoiding a sense of missing between the first display screen 1 and the second display screen 2. On the other hand, since the display screens in the prior art are usually arranged in a fitting manner, the display screens cannot be driven to rotate and fold when they are fitted. Therefore, when the first display screen 1 and the second display screen 2 in this application are driven to rotate and fold, the third display screen 4 moves outwards, which can ensure that the first display screen 1 and the second display screen 2 can be normally driven to rotate and fold.

[0026] The thickness of the first display screen 1 and the second display screen 2 is greater than that of the third display screen 4.

[0027] As Figure 2 and 3As shown in the figure, the third display screen 4 is arranged between the first display screen 1 and the second display screen 2. By setting the thickness of the third display screen 4 to be less than that of the first display screen 1 and the second display screen 2, it can effectively avoid interference with the third display screen 4 when the first display screen 1 and the second display screen 2 are folded inwardly, affecting the rotation of the first display screen 1 and the second display screen 2.

[0028] The working process of the present utility model is as follows: When the present utility model is in use, when it is necessary to fold the first display screen 1 and the second display screen 2, the handle 6 drives the screw rod 7 to rotate. During the rotation of the screw rod 7, through the threaded cooperation with the slider 10, the slider 10 is driven to slide along the axial direction of the screw rod 7. The slider 10 drives the lower end skateboard 12 to slide along the upper end surface of the limiting frame 8. The two ends of the skateboard 12 respectively drive the first supporting rod 9 and the second supporting rod 11 to deflect towards each other. The first supporting rod 9 and the second supporting rod 11 respectively drive the first display screen 1 and the second display screen 2 to deflect towards each other with the first supporting turntable 13 and the second supporting turntable 18 as axes, thereby folding the first display screen 1 and the second display screen 2. At the same time, when the first supporting turntable 13 and the second supporting turntable 18 rotate with the first display screen 1 and the second display screen 2 during driving rotation, the first supporting turntable 13 and the second supporting turntable 18 respectively drive the semi-gear 17 to rotate. When the semi-gear 17 rotates, it drives the sliding support block 15 at the lower end of the rack 16 to slide outwards under the limitation of the sliding pin 14. The sliding support block 15 drives the third display screen 4 to slide outwards, and the sliding direction is opposite to the deflection direction of the first display screen 1 and the second display screen 2. On the one hand, the third display screen 4 can make up for the gap between the first display screen 1 and the second display screen 2, avoiding a sense of deficiency between the first display screen 1 and the second display screen 2. On the other hand, since the display screens in the prior art are usually arranged in a fitting manner, the display screens cannot be driven to rotate and fold when they are fitted. Therefore, when the first display screen 1 and the second display screen 2 in this application are driven to rotate and fold, the third display screen 4 moves outwards, which can ensure that the first display screen 1 and the second display screen 2 can be normally driven to rotate and fold.
