Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and more specifically, it relates to a rotating and lifting intelligent LED display screen. Background Technology

[0002] LED displays are a new type of imaging electronic device made by arranging light-emitting diodes in sequence. Due to their high brightness, wide viewing angle, and long lifespan, they are widely used for information display and make it convenient for others to view.

[0003] In practical applications, different usage scenarios have diverse requirements for the display angle and height of the screen. For example, in a conference, the height and angle of the screen need to be flexibly adjusted according to the seating arrangement and viewing angle to achieve the best display effect.

[0004] Currently, the common method for adjusting the height of a display screen is to use a telescopic tube and bolts for fastening. When adjusting the height, it is necessary to first loosen the bolts, manually adjust the telescopic tube to the appropriate height, and then tighten the bolts to fix it. In terms of angle adjustment, the existing technology usually involves moving the entire display screen. Both adjustment methods have problems such as poor adjustment flexibility and laborious adjustment, which cannot meet the increasingly diverse practical application needs. Utility Model Content

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] Reference Figures 1-4A rotating and lifting intelligent LED display screen includes a base 1, with telescopic legs 2 symmetrically fixed at both ends of the base 1. A first support plate 3 is fixed to the top of the two telescopic legs 2. A vertical rod 4 is fixed in the middle of the base 1. A movable seat 5 is slidably sleeved on the vertical rod 4. The top of the movable seat 5 is fixedly connected to the bottom of the first support plate 3. A worm gear 6 and a worm wheel 7 are rotatably connected to the movable seat 5 through bearings. The worm wheel 7 meshes with the worm gear 6. A gear 8 is coaxially fixed on the worm wheel 7. A rack 9 that meshes with the gear 8 is vertically fixed on the side of the vertical rod 4 facing the gear 8. A rocker arm 10 extending to the outside of the movable seat 5 is coaxially fixed on the worm gear 6. A second support plate 11 is rotatably connected to the top of the first support plate 3 through bearings. A locking part 12 is provided between the second support plate 11 and the first support plate 3 to restrict their relative rotation. A mounting bracket 13 is fixedly fixed to the top of the second support plate 11. The display screen body 14 is fixedly fixed on the mounting bracket 13.

[0023] The locking part 12 includes a support 121 fixedly mounted on the first support plate 3. A locking block 122 is slidably connected to the support 121. The second support plate 11 has a circular structure, and the edge of the second support plate 11 is provided with a plurality of locking grooves 123. The plurality of locking grooves 123 are arranged in a ring array for the locking block 122 to be inserted into. An elastic element 124 is provided on the support 121. The elastic element 124 generates an outward sliding force on the locking block 122. The elastic element 124 is specifically a spring.

[0024] When it is necessary to release the restriction on the second support plate 11 to adjust the rotation angle of the display screen, the operator applies an inward force along the support 121 to the locking block 122, overcoming the outward sliding force exerted by the elastic element 124 on the locking block 122, causing the locking block 122 to exit from the slot 123 on the edge of the second support plate 11. At this time, the second support plate 11 can rotate freely relative to the first support plate 3. When the display screen body 14 rotates to the required angle, the force applied to the locking block 122 is released. Under the action of the elastic element 124, the locking block 122 slides outward and locks into the corresponding slot 123 on the edge of the second support plate 11, thereby restricting the rotation of the second support plate 11 relative to the first support plate 3, and fixing the display screen body 14 at the rotation angle. The locking part 12 has a simple structure and is easy to operate. Through the cooperation of the elastic element 124 and the locking block 122 with the slot 123, the restriction on the rotation of the second support plate 11 can be released and restored quickly and reliably, ensuring the convenience and stability of the display screen rotation angle adjustment.

[0025] A lever 125 is fixedly provided on the top of the locking block 122. The lever 125 allows the operator to apply force to the locking block 122, thereby overcoming the elastic resistance of the elastic element 124 and pushing the locking block 122 to slide smoothly.

[0026] Both sides of the end of the card block 122 facing the card slot 123 are provided with guide slopes 126. During the process of the card block 122 being inserted into the card slot 123, the guide slopes 126 on the card block 122 will play a guiding role, which helps the card block 122 to be inserted into the card slot 123 smoothly.

[0027] Two positioning strips 15 are fixedly sleeved on the upright 4. The two positioning strips 15 are located on both sides of the movable seat 5 and slide to limit it. The positioning strips 15 ensure that the movable seat 5 moves within the expected range and ensure that the gear 8 and the rack 9 maintain good meshing and transmission.

[0028] Working principle: When the display height of the LED display needs to be adjusted, the operator rotates the rocker arm 10 according to the actual needs. The rocker arm 10 drives the worm gear 6 to rotate, which in turn drives the worm wheel 7 to rotate. The gear 8 rotates synchronously. Under the action of the rotation of the gear 8, according to the meshing transmission principle of the gear 8 and the rack 9, the entire moving base 5 will slide in a straight line along the upright 4, thereby causing the first support plate 3, the second support plate 11 and the display body 14 connected to it to change in the height direction, thus realizing the adjustment of the display height.

[0029] The two symmetrically arranged telescopic outriggers 2 provide guidance for the lifting and lowering of the second support plate 11, enabling it to be adjusted in height smoothly;

[0030] Because of the self-locking property between the worm gear 7 and the worm 6, when the rocker arm 10 is released, the worm gear 7 cannot push the worm 6 to rotate in the opposite direction. This fixes the position of the movable seat 5 on the upright 4, so that the display screen body 14 can be stably maintained at the adjusted height for use.

[0031] When it is necessary to adjust the rotation angle of the display screen, firstly, the locking part 12 is released, which releases the restriction on the second support plate 11, allowing the second support plate 11 to rotate flexibly relative to the first support plate 3, thereby driving the display screen body 14 to rotate synchronously. After the display screen body 14 rotates to the required angle, the locking part 12 is used again to restrict the position of the second support plate 11, preventing it from rotating on its own under the action of other external forces and deviating from the required angle.

[0032] This application achieves flexible adjustment of the display screen height through the rocker arm 10 and the transmission structure of the worm gear 7, worm 6, gear 8, and rack 9. By setting up a first support plate 3 and a second support plate 11 that can rotate relative to each other, and cooperating with the locking part 12, the rotation angle of the display screen can be flexibly adjusted, which meets the diverse needs of different usage scenarios for the display screen height and angle, overcomes the problems of poor adjustment flexibility and laborious adjustment in the prior art, and improves the user experience.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
