Description

Technical Field

[0001] This utility model relates to the field of LED displays, and in particular to a self-rotation adjustment support structure for LED displays. Background Technology

[0002] An LED display screen self-rotation adjustment support structure is a bracket used to adjust and fix an LED display screen. It allows the display screen to be adjusted at multiple angles in a plane, thereby enabling multi-directional display and improving the practicality of the LED display screen.

[0003] Existing LED display screen self-rotation adjustment support structures typically use gear meshing to rotate the connecting shaft of the frame, thereby driving the display screen to rotate. However, they lack auxiliary positioning functions for the connecting shaft. When the display screen is subjected to external forces, the connecting shaft may rotate, causing the display screen angle to shift.

[0004] Therefore, the existing LED display screen rotation adjustment support structure typically uses gear meshing to rotate the connecting shaft of the frame, thus driving the display screen to rotate. However, it lacks an auxiliary positioning function for the connecting shaft. When the display screen is subjected to external forces, the connecting shaft may rotate, causing the display screen angle to deviate. A new LED display screen rotation adjustment support structure can be designed. By setting a first drive motor, its output end will drive a bidirectional screw to rotate during operation. When the bidirectional screw rotates, it can drive two moving seats that are threaded together to move in opposite directions. When the moving seats move, they can drive the connecting rod to move synchronously, thereby allowing the two grippers to clamp the rotating shaft, thus positioning the rotating shaft and preventing it from rotating after debugging, improving the overall stability of the device. Utility Model Content

[0005] To overcome the problem that existing LED display screen self-rotation adjustment support structures typically use gear meshing to rotate the connecting shaft of the frame, thereby driving the display screen to rotate, but lack auxiliary positioning function for the connecting shaft, the connecting shaft may rotate when the display screen is subjected to external forces, causing the display screen angle to deviate.

[0006] The technical solution of this utility model is as follows: an LED display screen self-rotation adjustment support structure, including a base; it also includes a device base, a first drive motor, a bidirectional screw, a movable seat, a connecting rod, and a gripper. A driven gear is rotatably connected to the middle of the inner bottom surface of the base. A rotating shaft is provided at the middle of the top surface of the driven gear. The top of the rotating shaft passes through the upper surface of the base and is connected to a turntable. A support rod is provided on the top surface of the turntable. A mounting frame is provided on the top of the support rod. A device base is provided at the rear side of the upper surface of the base. A first drive motor is provided on the right side surface of the device base. The output end of the first drive motor passes through the right side surface of the device base and is connected to one end of the bidirectional screw. The other end of the bidirectional screw is rotatably connected to the left side of the inner surface of the device base. Two symmetrical movable seats are threaded through the outer surface of the bidirectional screw. A connecting rod is provided on the front surface of the movable seat, and a gripper is provided on the other end of the connecting rod.

[0007] Preferably, by setting a first drive motor, its output end will drive the bidirectional screw to rotate during operation. When the bidirectional screw rotates, it can drive the two moving seats that are threaded with it to move in opposite directions. When the moving seats move, they can drive the connecting rod to move synchronously, so that the two grippers clamp the rotating shaft, thereby playing a role in positioning the rotating shaft and preventing the rotating shaft from rotating after the debugging is completed. This improves the overall stability of the device. This solves the problem that the existing LED display screen self-rotation adjustment support structure usually uses gear meshing transmission to rotate the connecting shaft of the frame to achieve the function of driving the screen to rotate. However, it lacks the auxiliary positioning function of the connecting shaft. When the screen is subjected to external forces, the connecting shaft may rotate, causing the screen angle to deviate.

[0008] Preferably, both gripper surfaces are provided with anti-slip pads made of rubber.

[0009] Preferably, a bearing is embedded in the middle of the upper surface of the base, and the inner ring surface of the bearing is connected to the outer surface of the rotating shaft.

[0010] Preferably, a second drive motor is provided at the bottom of the inner surface of the base, to the right of the driven gear, and a drive gear is provided at the output end of the second drive motor, which meshes with the driven gear.

[0011] Preferably, the inner surface of the base has equally spaced heat dissipation vents on both the left and right sides.

[0012] Preferably, dustproof nets are provided on both the left and right sides of the base at the positions corresponding to the heat dissipation vents, and fixing screws are provided at the four corners of the dustproof nets, which are then fixed to the base.

[0013] Preferably, casters are provided at the corners of the bottom surface of the base, and the casters are fixed to the base by external bolts.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a first drive motor, its output end will drive the bidirectional screw to rotate during operation. When the bidirectional screw rotates, it can drive the two moving seats that are threaded with it to move in opposite directions. When the moving seats move, they can drive the connecting rod to move synchronously, so that the two grippers can clamp the rotating shaft, thereby playing a role in positioning the rotating shaft and preventing the rotating shaft from rotating after debugging. This improves the overall stability of the device. This solves the problem that the existing LED display screen self-rotation adjustment support structure usually uses gear meshing transmission to rotate the connecting shaft of the frame to achieve the function of driving the screen to rotate. However, it lacks the auxiliary positioning function of the connecting shaft. When the screen is subjected to external forces, the connecting shaft may rotate, causing the screen angle to deviate.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of an LED display screen self-rotation adjustment support structure, including a base 1; it also includes a device base 7, a first drive motor 8, a bidirectional screw 9, a movable seat 10, a connecting rod 11, and a gripper 12. A driven gear 2 is rotatably connected to the middle of the inner bottom surface of the base 1. A rotating shaft 3 is provided at the middle of the top surface of the driven gear 2. The top of the rotating shaft 3 passes through the upper surface of the base 1 and is connected to a turntable 4. A support rod 5 is provided on the top surface of the turntable 4, and a mounting frame 6 is provided on the top of the support rod 5. The device base 7 is provided at the rear side of the upper surface of the base 1. The first drive motor 8 is provided on the right side surface of the device base 7. The output end of the first drive motor 8 passes through the right side surface of the device base 7 and is connected to one end of the bidirectional screw 9. The other end of the bidirectional screw 9 is rotatably connected to the left side of the inner surface of the equipment base 7. The outer surface of the bidirectional screw 9 is threadedly connected to two symmetrical movable seats 10. One end of the connecting rod 11 is provided on the front surface of the movable seat 10, and the other end of the connecting rod 11 is provided with a gripper 12. By setting the first drive motor 8, its output end will drive the bidirectional screw 9 to rotate during operation. When the bidirectional screw 9 rotates, it can drive the two movable seats 10 that are threaded with it to move in opposite directions. When the movable seats 10 move, they can drive the connecting rod 11 to move synchronously, so that the two grippers 12 can clamp the rotating shaft 3, thereby playing a role in positioning the rotating shaft 3 and preventing the rotating shaft 3 from rotating after debugging, thus improving the overall stability of the device.

[0023] Please see Figures 2-4 In this embodiment, the clamping surfaces of both grippers 12 are provided with anti-slip plates 13. The anti-slip plates 13 are made of rubber. By providing anti-slip plates 13 made of rubber, the friction between the gripper and the rotating shaft 3 can be increased, thereby improving the clamping effect and preventing the rotating shaft 3 from rotating. A bearing 14 is embedded in the middle of the upper surface of the base 1. The inner ring surface of the bearing 14 is connected to the outer surface of the rotating shaft 3. By providing the bearing 14, the rotating shaft 3 can be assisted to rotate, thereby improving the overall stability of the device in angle adjustment. A second drive motor 15 is provided at the bottom of the inner surface of the base 1, to the right of the driven gear 2. The output end of the second drive motor 15 is provided with a drive gear 16. The drive gear 16 meshes with the driven gear 2. By providing the second drive motor 15, its output end will drive the drive gear 16 to rotate during operation. When the drive gear 16 rotates, it can drive the driven gear 2 meshing with it to rotate, thereby completing the angle adjustment of the display screen.

[0024] Please see Figures 1-4In this embodiment, the inner surface of the base 1 is provided with equally spaced heat dissipation vents 17 on both the left and right sides. By setting the heat dissipation vents 17, the heat dissipation effect inside the base 1 can be improved, and the overheating of the second drive motor 15 can be avoided, which may cause damage to the components. Dustproof nets 18 are provided on both the left and right sides of the base 1 at the positions corresponding to the heat dissipation vents 17. Fixing screws 19 are provided at the four corners of the dustproof nets 18. The dustproof nets 18 are fixed to the base 1 by the fixing screws 19. By setting the dustproof nets 18, dust can be prevented from entering the interior of the base 1 from the heat dissipation vents 17, thus ensuring the cleanliness of the interior of the base 1. Universal wheels 20 are provided at the corners of the bottom surface of the base 1. The universal wheels 20 are fixed to the base 1 by external bolts. By setting the universal wheels 20, it is easy for the staff to move the whole device, which improves the convenience of use.

[0025] During operation, the rubber anti-slip pads 13 increase the friction between the contact surface and the rotating shaft 3, thereby improving the clamping effect and preventing the rotating shaft 3 from rotating. The bearings 14 assist the rotating shaft 3 in rotating, improving the overall stability of the device during angle adjustment. The second drive motor 15 drives the drive gear 16 to rotate during operation. The drive gear 16, when rotating, drives the driven gear 2 meshing with it to rotate, thereby completing the angle adjustment of the display screen. The heat dissipation vents 17 improve the heat dissipation effect inside the base 1, preventing the second drive motor 15 from overheating and damaging the components. The dustproof net 18 prevents dust from entering the interior of the base 1 through the heat dissipation vents 17, ensuring the cleanliness of the interior of the base 1. The casters 20 facilitate the movement of the entire device by the operator, improving the convenience of use.

[0026] Through the above steps, by setting the first drive motor 8, its output end will drive the bidirectional screw 9 to rotate during operation. When the bidirectional screw 9 rotates, it can drive the two moving seats 10 that are threaded with it to move in opposite directions. When the moving seats 10 move, they can drive the connecting rod 11 to move synchronously, so that the two grippers 12 can clamp the rotating shaft 3, thereby playing a role in positioning the rotating shaft 3 and preventing the rotating shaft 3 from rotating after debugging. This improves the overall stability of the device. This solves the problem that the existing LED display screen self-rotation adjustment support structure usually uses gear meshing transmission to rotate the connecting shaft of the frame to achieve the function of driving the display screen to rotate. However, it lacks the auxiliary positioning function of the connecting shaft. When the display screen is subjected to external forces, the connecting shaft may rotate, causing the display screen angle to deviate.
