Description

Technical Field

[0001] This invention relates to the field of advertising displays, and more particularly to an anti-magnetic LED display screen. Background Technology

[0002] LED displays rely on the electromagnetic wave modulation characteristics of metamaterials as a technological support, and achieve stable and efficient device integration based on hybrid substrates. With high-brightness diodes as the core display unit, they present an immersive naked-eye 3D effect through a precision optical structure, injecting innovative momentum into advertising and marketing by integrating virtual and real elements. At the same time, in order to prevent the LED display from being affected by the magnetic force of the internal magnetic connectors and attracting metal dust, magnetic shielding is usually placed on the outside of the magnetic connectors to prevent magnetic leakage.

[0003] At various event sites, LED displays often need to be temporarily installed on the steel frame of glass partitions to display advertisements and other information. However, in the actual installation process, since there is no pre-fitting installation structure on the steel frame of the glass partition, a special mounting bracket must be welded onto the steel frame before the LED display can be mounted and installed. The installation process is time-consuming, resulting in low efficiency of temporary installation. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing an anti-magnetic adsorption LED display screen.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an anti-magnetic adsorption LED display screen, comprising an LED display screen, a threaded rod horizontally installed at the middle of the rear end of the LED display screen housing, the threads at both ends of the threaded rod being symmetrically arranged, two threaded sleeves symmetrically screwed onto the outer surface of the threaded rod, a horizontal clamping block extending from the rear end of each of the two threaded sleeves, the two horizontal clamping blocks being symmetrically arranged, two support frames symmetrically arranged in front of the threaded rod, the support frames being fixed to the rear end of the LED display screen housing, two vertical clamping plates symmetrically slidably installed on the outer surface of the support frames, concave levers elastically installed on the opposite sides of the two support frames, push plate frames connecting the two ends of the concave levers to the two vertical clamping plates, a control plate fixedly installed at the front end of the threaded sleeves, a fixing lug extending from the front end of the control plate, the fixing lug pressing against the concave lever, and an adsorption component installed at the rear end of the LED display screen housing.

[0006] Preferably, one end of the push plate frame is rotatably connected to the end of the concave lever frame, and the opposite surfaces of the two vertical clamps each extend with a connecting ear, and the other end of the push plate frame is rotatably connected to the end of the connecting ear.

[0007] Preferably, two guide posts are symmetrically fixedly installed on the side of the concave lever, the support frame is slidably installed on the outer surface of the guide posts, a retractable spring is wound around the outside of the guide posts, one end of the retractable spring is fixed to the side of the support frame, the other end of the retractable spring is fixed to the side of the concave lever, and a limit cap is coaxially fixedly installed at the end of the guide post.

[0008] Preferably, two horizontal positioning frames are symmetrically and rotatably installed on the middle of the outer surface of the threaded rod. The front end of the horizontal positioning frame is fixed to the rear end of the LED display screen cabinet. Both ends of the threaded rod are rotatably installed with pole carriers. The front end of the pole carriers is fixed to the rear end of the LED display screen cabinet. The distance between the two horizontal positioning frames is adapted to the distance between two adjacent vertical steel frames of the glass partition. Vertical positioning plates are fixedly installed at the upper and lower ends of the support frame. The distance between the two vertical positioning plates is adapted to the distance between two adjacent horizontal steel frames of the glass partition.

[0009] Preferably, guide rails are fixedly installed at the upper and lower ends of the two horizontal positioning frames, and the ends of the guide rails are fixed to the rod carrier. Guide ears extend from the upper and lower ends of the threaded sleeve, and the guide ears are slidably installed inside the guide rails.

[0010] Preferably, the adsorption component includes two sets of fixed plate frames symmetrically fixedly installed at the rear end of the LED display screen housing, with two support frames located between the two sets of fixed plate frames. Each set of fixed plate frames contains two fixed plate frames. The ends of both fixed plate frames are connected to hand pump suction cups, which are located above and below the threaded rod, respectively. A plate rod is fixedly installed between the opposite surfaces of the two fixed plate frames. Two pressure handle plates are symmetrically slidably installed on the outer surface of the plate rod. The two pressure handle plates are respectively attached to the pump handle ends of the two hand pump suction cups. The upper and lower ends of the control plate are wavy. Pressure handle wheels are connected to the opposite surfaces of the two pressure handle plates, and the two pressure handle wheels are respectively attached to the upper and lower ends of the control plate.

[0011] Preferably, a return spring is wound around the upper and lower parts of the outer surface of the plate rod. One end of the return spring is fixed to the fixed plate frame, and the other end of the return spring is fixed to the pressure handle plate. A limit groove is formed on the outer surface of the plate rod, and a limit slider extends from the inner surface of the pressure handle plate. The limit slider is slidably installed inside the limit groove. A wheel support is connected to the end of the wheel axle of the pressure handle wheel, and the end of the wheel support is fixed to the pressure handle plate.

[0012] Preferably, a first clamping ring is fixedly installed at the end of the fixed plate frame, and a second clamping ring is fixedly installed at the rear end of the first clamping ring by screws. The first and second clamping rings are clamped to the outer surface of the pump body of the hand pump suction cup.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The rotating threaded rod drives two threaded sleeves to move towards each other, which in turn drives two horizontal clamping blocks to move towards each other. This allows the two horizontal clamping blocks to clamp onto the opposite surfaces of two adjacent vertical steel frames of the glass partition. During this process, the moving threaded sleeves also drive the control plate to move, causing the fixed lugs on the control plate to push the concave lever, thereby driving the push plate frame to move and pushing the two vertical clamping plates to move in opposite directions. This allows the two vertical clamping plates to press against the opposite surfaces of two adjacent horizontal steel frames of the glass partition. Under the clamping of the horizontal clamping blocks and vertical clamping plates, the LED display screen is installed on the steel frame of the glass partition. This process eliminates the need to weld mounting brackets onto the steel frame of the glass partition before installation, effectively saving time and improving the efficiency of temporary installation.

[0014] 2. With the control panel's upper and lower ends arranged in a wave-like pattern, as the control panel moves, it continuously pushes the pressure handle wheel, thereby causing the two pressure handle plates to move in opposite directions. This continuously presses the pump handle of the hand pump suction cup, expelling the air between the hand pump suction cup and the glass of the glass partition. This allows the hand pump suction cup to firmly adhere to the glass of the glass partition, strengthening the restraint force on the LED display screen and ensuring its secure fixation. This guarantees the stability of the installation. Simultaneously, simply rotating the threaded rod completes the operation of clamping the horizontal clamping block and vertical clamping plate onto the vertical and horizontal steel frames of the glass partition, as well as allowing the hand pump suction cup to adhere to the glass of the glass partition. The process is simple to operate and effectively facilitates use. Attached Figure Description

[0017] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] like Figures 1-10The diagram illustrates an anti-magnetic adsorption LED display screen, comprising an LED display screen 1. A magnetic shield is provided on the outer side of the magnetic connector inside the LED display screen 1 to prevent magnetic leakage and thus prevent the LED display screen from adsorbing metal dust due to the magnetic force of the internal magnetic connector. Since this anti-magnetic adsorption method is existing technology and has been disclosed in patent application CN201921286803.2, it is not described in detail here. A threaded rod 5 is horizontally installed at the middle of the rear end of the LED display screen 1. The threads at both ends of the threaded rod 5 are symmetrically arranged. Two threaded sleeves 16 are symmetrically screwed onto the outer surface of the threaded rod 5. The symmetrical arrangement of the threads at both ends of the threaded rod 5 allows the two threaded sleeves 16 to move towards each other. A horizontal clamping block 17 extends from the rear end of each of the two threaded sleeves 16. The two horizontal clamping blocks 17 are symmetrically arranged. The two threaded sleeves 16 drive the two horizontal clamping blocks 17 to move towards each other, allowing the two horizontal clamping blocks 17 to clamp onto two adjacent glass partitions 31. On the opposite side of the vertical steel frame, two support frames 7 are symmetrically arranged in front of the threaded rod 5. The support frames 7 are fixed to the rear end of the LED display screen 1. Two vertical clamping plates 9 are symmetrically slidably installed on the outer surface of the support frames 7, and the support frames 7 serve to guide the vertical clamping plates 9. Concave levers 14 are elastically installed on the opposite sides of the two support frames 7. Push plate frames 10 are connected between the two ends of the concave levers 14 and the two vertical clamping plates 9. The concave levers 14 drive the push plate frames 10 to move. Threaded sleeve 1 A control plate 11 is fixedly installed at the front end of the LED display screen 1. A fixed lug 24 extends from the front end of the control plate 11. The fixed lug 24 is pressed against the concave lever 14. The threaded sleeve 16 drives the control plate 11 to move, so that the fixed lug 24 on the control plate 11 pushes the concave lever 14, thereby driving the push plate frame 10 to move and pushing the two vertical clamps 9 to move in opposite directions, so that the two vertical clamps 9 can press against the opposite surfaces of the two adjacent horizontal steel frames of the glass partition 31. An adsorption component is installed at the rear end of the LED display screen 1.

[0019] One end of the push plate frame 10 is rotatably connected to the end of the concave lever frame 14. The opposite surfaces of the two vertical clamping plates 9 each have connecting ears 28. The other end of the push plate frame 10 is rotatably connected to the end of the connecting ear 28. The connecting ear 28 serves to facilitate connecting the push plate frame 10 and the vertical clamping plates 9 together.

[0020] Two guide posts 26 are symmetrically fixedly installed on the side of the concave lever 14. The support frame 7 is slidably installed on the outer surface of the guide posts 26. The guide posts 26 guide the concave lever 14. A coiling spring 27 is wound around the outside of the guide posts 26. One end of the coiling spring 27 is fixed to the side of the support frame 7, and the other end of the coiling spring 27 is fixed to the side of the concave lever 14. The coiling spring 27 can push the concave lever 14 to move laterally and reset, thereby driving the two vertical clamps 9 to reset and converge. A limit cap 25 is coaxially fixedly installed at the end of the guide post 26. The limit cap 25 prevents the concave lever 14 and the support frame 7 from separating.

[0021] Two horizontal positioning frames 6 are symmetrically and rotatably installed on the middle of the outer surface of the threaded rod 5. The front end of the horizontal positioning frame 6 is fixed to the rear end of the LED display screen 1. The horizontal positioning frame 6 can be used for positioning and to strengthen the connection strength of the threaded rod 5. Both ends of the threaded rod 5 are rotatably installed with rod carriers 2, which serve to support the threaded rod 5. The front end of the rod carrier 2 is fixed to the rear end of the LED display screen 1. The distance between the two horizontal positioning frames 6 is adapted to the distance between the two adjacent vertical steel frames of the glass partition 31. Vertical positioning plates 8 are fixedly installed at the upper and lower ends of the support frame 7. The distance between the two vertical positioning plates 8 is adapted to the distance between the two adjacent horizontal steel frames of the glass partition 31. This allows the vertical positioning plates 8 to be close to the opposite surface of the horizontal steel frame of the glass partition 31, and the horizontal positioning frames 6 to be close to the opposite surface of the vertical steel frame of the glass partition 31 for positioning.

[0022] Guide rails 18 are fixedly installed at the upper and lower ends of the two horizontal positioning frames 6. The ends of the guide rails 18 are fixed to the rod carrier 2. Guide ears 15 extend from the upper and lower ends of the threaded sleeve 16. The guide ears 15 are slidably installed inside the guide rails 18. The cooperation between the guide rails 18 and the guide ears 15 prevents the threaded sleeve 16 from rotating.

[0023] The adsorption component includes two sets of fixed plate frames 4 symmetrically fixedly installed at the rear end of the LED display screen 1 housing. Two support frames 7 are located between the two sets of fixed plate frames 4. Each set of fixed plate frames 4 consists of two pieces. A hand pump suction cup 3 is connected to the end of each of the two fixed plate frames 4. The hand pump suction cup 3 is model BX1. Since adsorption is achieved by continuously pressing the handle of the hand pump suction cup 3, and this technology is widely used, the specific structure of the hand pump suction cup 3 is not described in detail here. The fixed plate frames 4 serve to support the hand pump suction cup 3. The two hand pump suction cups 3 are located above and below the threaded rod 5, respectively. A plate rod 23 is fixedly installed between the opposite faces of the two fixed plate frames 4. Two pressure handle plates 13 are symmetrically slidably installed on the outer surface of the plate rod 23. The control plate 11 serves to guide the pressure plate 13. The two pressure plates 13 are respectively attached to the pump handle ends of the two hand pump suction cups 3. The upper and lower ends of the control plate 11 are wavy. The opposing surfaces of the two pressure plates 13 are connected to pressure wheels 22. The two pressure wheels 22 are respectively attached to the upper and lower ends of the control plate 11. When the control plate 11 moves, it will use the wavy surfaces of the upper and lower ends to continuously push the pressure wheels 22, thereby driving the two pressure plates 13 to move in opposite directions continuously, so as to continuously press the pump handle of the hand pump suction cup 3, so that the air between the hand pump suction cup 3 and the glass of the glass partition 31 is discharged, allowing the hand pump suction cup 3 to be firmly attached to the glass of the glass partition 31, thereby strengthening the restraining force on the LED display screen 1 and firmly fixing the LED display screen 1.

[0024] The upper and lower parts of the outer surface of the rod 23 are wound with return springs 12. One end of the return spring 12 is fixed to the fixed plate 4. The return spring 12 serves to keep the pressure handle wheel 22 in contact with the control plate 11. The other end of the return spring 12 is fixed to the pressure handle plate 13. A limit groove 19 is opened on the outer surface of the rod 23. A limit slider 20 extends from the inner surface of the pressure handle plate 13. The limit slider 20 is slidably installed inside the limit groove 19. The cooperation between the limit slider 20 and the limit groove 19 serves to prevent the pressure handle plate 13 from rotating. The end of the axle of the pressure handle wheel 22 is connected to a wheel support 21. The end of the wheel support 21 is fixed to the pressure handle plate 13. The wheel support 21 serves to support the pressure handle wheel 22.

[0025] A first clamping ring 29 is fixedly installed at the end of the fixed plate frame 4. A second clamping ring 30 is fixedly installed at the rear end of the first clamping ring 29 by screws. The first clamping ring 29 and the second clamping ring 30 are clamped to the outer surface of the pump body of the hand pump suction cup 3. The first clamping ring 29 and the second clamping ring 30 can adapt to the shape of the hand pump suction cup 3 and fix the hand pump suction cup 3 and the fixed plate frame 4 together.

[0026] During installation, the LED display screen 1 is placed on the glass partition 31. The vertical positioning plate 8 is pressed against the opposite surface of the horizontal steel frame of the glass partition 31, and the horizontal positioning frame 6 is pressed against the opposite surface of the vertical steel frame of the glass partition 31 for positioning. Simultaneously, the hand pump suction cup 3 is pressed against the glass surface of the glass partition 31. Then, the threaded rod 5 is rotated to move the two threaded sleeves 16 towards each other, thereby moving the two horizontal clamping blocks 17 towards each other. This allows the two horizontal clamping blocks 17 to clamp onto the opposite surfaces of two adjacent vertical steel frames of the glass partition 31. During this process, the moving threaded sleeves 16 also move the control plate 11, causing the fixing lugs 24 on the control plate 11 to push the concave lever 14, thereby moving the push plate frame 10 and pushing the two vertical clamping plates 9 to move in opposite directions. This allows the two vertical clamping plates 9 to press against the opposite surfaces of two adjacent horizontal steel frames of the glass partition 31, thus securing the horizontal clamping blocks... 17. With the vertical clamping plate 9 clamping, the LED display screen 1 is installed on the steel frame of the glass partition 31. At the same time, when the control plate 11 moves, it will also use the wavy surface at the upper and lower ends to continuously push the pressure handle wheel 22, thereby driving the two pressure handle plates 13 to move in opposite directions continuously, so as to continuously press the pump handle of the hand pump suction cup 3, so that the air between the hand pump suction cup 3 and the glass of the glass partition 31 is discharged, allowing the hand pump suction cup 3 to be firmly attached to the glass of the glass partition 31, thereby strengthening the restraining force on the LED display screen 1 and firmly fixing the LED display screen 1. Then, the LED display screen 1 can be used to display advertisements and other information. In the above process, only rotating the threaded rod 5 can simultaneously complete the operation of clamping the horizontal clamping block 17 and the vertical clamping plate 9 on the vertical and horizontal steel frames of the glass partition 31, and allowing the hand pump suction cup 3 to be attached to the glass of the glass partition 31, which effectively facilitates the use.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
