Description

Technical Field

[0001] This utility model relates to the field of display screen technology, specifically a modular splicing LED display screen and plastic kit. Background Technology

[0002] With the rapid development of display technology, LED displays have been widely used in advertising media, stage performances, sports venues, smart cities, and other fields due to their advantages such as high brightness, high contrast, long lifespan, and energy saving and environmental protection. However, traditional LED displays mostly adopt an integrated or fixed splicing structure, which has shortcomings such as insufficient installation flexibility and low maintenance efficiency.

[0003] When using this device, traditional displays require specialized tools for overall disassembly and assembly. Especially when replacing faulty modules, it is necessary to disassemble the surrounding components one by one, which is time-consuming and prone to secondary damage. Therefore, we need to propose a modular splicing LED display and plastic kit. Utility Model Content

[0004] The purpose of this utility model is to provide a modular splicing LED display screen and plastic kit, which, by setting up components such as guide rails and damping plates, facilitates the individual installation and removal of multiple display panels, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A modular LED display screen includes:

[0007] The mounting frame has multiple evenly distributed guide rails fixedly connected inside. Multiple damping plates are slidably connected inside each of the multiple guide rails. Mounting tubes are in contact with the side walls of each of the multiple damping plates. Screws are threadedly connected inside each of the multiple mounting tubes. Mounting plates are fixedly connected to the ends of each of the multiple screws. Each of the multiple mounting plates is in contact with the multiple guide rails. Display panels are fixedly connected to the side walls of each of the multiple mounting plates. Multiple LED beads are provided on the side walls of each of the multiple display panels.

[0008] Preferably, two symmetrically distributed fixing brackets are fixedly connected to the side walls of each of the plurality of mounting tubes, and the plurality of fixing brackets are slidably connected to the plurality of damping plates respectively.

[0009] Preferably, springs are fitted on the outer sides of each of the plurality of fixing frames.

[0010] Preferably, a limit ring is fixedly connected to the outer side of each of the plurality of mounting tubes.

[0011] Preferably, each of the multiple guide rails has a sliding groove inside, and the multiple sliding grooves respectively contact multiple limiting rings.

[0012] Preferably, a top plate is bolted to the upper end of the mounting frame, and the top plate contacts multiple guide rails respectively.

[0013] A plastic kit includes a modular splicing LED display screen and a first magnetic block. A plurality of first magnetic blocks are fixedly connected to the side walls of the plurality of display panels in a ring. A transparent shell is in contact with the side walls of the plurality of display panels. A plurality of second magnetic blocks are fixedly connected to the interior of the plurality of transparent shells in a ring. The plurality of second magnetic blocks are magnetically connected to the plurality of first magnetic blocks respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model incorporates components such as guide rails and damping plates. The guide rails provide precise guidance during installation, ensuring rapid positioning of the display panel. The damping plate, after being frosted, forms a stable frictional force with the guide rail surface. This allows for non-destructive disassembly via a compression spring and automatic locking during resetting, preventing loosening of the joints. This design requires no complex tools, allowing a single person to complete modular operation, shortening maintenance time, and ensuring the long-term stability of the display unit under vibration.

[0024] 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.

[0025] Please see Figure 1-7 This utility model provides a technical solution:

[0026] A modular LED display screen includes:

[0027] The mounting frame 1 has multiple evenly distributed guide rails 3 fixedly connected inside. Multiple damping plates 4 are slidably connected inside each guide rail 3. Mounting tubes 5 are in contact with the side walls of each damping plate 4. Screws 10 are threadedly connected inside each mounting tube 5. Mounting plates 11 are fixedly connected to the ends of each screw 10. Each mounting plate 11 is in contact with each guide rail 3. Display plates 12 are fixedly connected to the side walls of each mounting plate 11. Multiple LED beads 13 are provided on the side walls of each display plate 12.

[0028] For example, the mounting frame 1 is made of high-strength aluminum alloy profile, and multiple guide rails 3 are evenly distributed inside through precision machining. The lower ends of the multiple guide rails 3 are connected by a connecting plate. The connecting plate limits the damping plate 4 and the mounting tube 5 to prevent the mounting tube 5 from falling downward. The damping plate 4 is injection molded from polyoxymethylene (POM) engineering plastic, and its surface is frosted to enhance friction. The mounting tube 5 is a hollow cylindrical structure with threaded holes inside for threaded connection with the screw 10. The screw 10 is made of stainless steel, and its end is fixedly connected to the mounting plate 11 through cold forging process. The mounting plate 11 is galvanized steel plate with epoxy resin anti-rust paint sprayed on the surface. The display panel 12 is a PCB substrate with multiple LED beads 13 evenly distributed on its surface. The spacing of the LED beads 13 can be selected according to the pixel density requirements, such as P2.5 / P3 / P4.

[0029] Two symmetrically distributed fixing brackets 6 are fixedly connected to the side walls of multiple mounting tubes 5. The multiple fixing brackets 6 are slidably connected to multiple damping plates 4 respectively, and springs 7 are sleeved on the outer side of the multiple fixing brackets 6.

[0030] For example, the fixing frame 6 is made of aluminum alloy extrusion molding. The sliding end of the fixing frame 6 is provided with a cylindrical slide rod. The surface of the slide rod is plated with hard chrome to reduce the coefficient of friction. The damping plate 4 is provided with a guide hole at the corresponding position to ensure smooth sliding. The spring 7 is a stainless steel compression spring to keep the damping plate 4 in stable contact with the mounting tube 5. The spring 7 is a compression spring so that the spring 7 always has a pushing force on the guide rail 3 on the damping plate 4, which facilitates the control of the position of the damping plate 4.

[0031] Multiple mounting tubes 5 are fixedly connected to the outer side of each limiting ring 8, and multiple guide rails 3 are provided with sliding grooves 9 inside each, with each sliding groove 9 contacting the multiple limiting rings 8 respectively.

[0032] For example, the limiting ring 8 is made of stainless steel. When the sliding damping plate 4 is sliding, the limiting ring 8 limits the mounting tube 5 under the limiting action of the sliding groove 9, preventing the mounting tube 5 from falling out of the guide rail 3. At the same time, it does not affect the up and down movement of the mounting tube 5 inside the guide rail 3, which is convenient for the use of the mounting tube 5 in different positions. At the same time, the limiting ring 8 does not affect the rotation of the mounting tube 5, which is convenient for the threaded movement between the mounting tube 5 and the screw 10.

[0033] A top plate 2 is bolted to the upper end of the mounting frame 1, and the top plate 2 contacts multiple guide rails 3 respectively.

[0034] For example, the top plate 2 is bolted to the upper end of the mounting frame 1, which facilitates the top plate 2 to limit the guide rail 3. At the same time, the top plate 2 and the mounting frame 1 form a fixed frame, which can support the display panel 12.

[0035] A plastic kit includes a modular splicing LED display screen and a first magnetic block 14. A plurality of first magnetic blocks 14 are fixedly connected to the side walls of a plurality of display panels 12 in a ring. A transparent shell 15 is in contact with the side walls of the plurality of display panels 12. A plurality of second magnetic blocks 16 are fixedly connected to the interior of the plurality of transparent shells 15 in a ring. The plurality of second magnetic blocks 16 are magnetically connected to the plurality of first magnetic blocks 14 respectively.

[0036] For example, each display panel 12 has multiple annularly distributed first magnetic blocks 14 fixedly connected to its sidewall via an insert injection molding process. The first magnetic blocks 14 are neodymium iron boron strong magnets with nickel plating for rust prevention. The transparent shell 15 is made of PC (polycarbonate) material and is injection molded with high precision, giving it high hardness and light transmittance. The inner wall of the transparent shell 15 has multiple annularly distributed grooves for fixing second magnetic blocks 16. The second magnetic blocks 16 are ferrite magnets with epoxy resin insulating paint sprayed on their surface. When two display panels 12 are spliced ​​together, the first magnetic blocks 14 and the second magnetic blocks 16 automatically attract each other. The transparent shell 15 not only protects the LED beads 13 from collisions.

[0037] Working principle: During installation, the damping plate 4 is moved to adjust the position of the mounting tube 5. When it is moved to the appropriate position, the damping plate 4 is pulled out and rotated. The damping plate 4 drives the mounting tube 5 to rotate through the fixing bracket 6. After the screw 10 is installed inside the mounting tube 5, the damping plate 4 is released. Under the elastic force of the compression spring 7, the damping plate 4 is stuck inside the guide rail 3. The guide rail 3 limits the mounting tube 5 and installs the display panel 12. After the lower display panel 12 is installed, the upper display panel 12 is installed. The lower display panel 12 supports the upper display panel 12. At the same time, the spring 7 ensures that the damping plate 4 and the guide rail 3 maintain stable contact. The damping plate 4 uses friction to limit the damping plate 4 without the display panel 12 installed.

[0038] The fixing frame 6 is fixed to the side wall of the mounting tube 5 by riveting. The cylindrical slide rod with hard chrome plated at its sliding end is inserted into the guide hole of the damping plate 4. By moving the damping plate 4, the spring 7 is compressed. At the same time, the damping plate 4 is disengaged from the limit of the guide rail 3 and rotated. The damping plate 4 drives the mounting tube 5 to rotate through the fixing frame 6. The mounting tube 5 and the screw 10 have a threaded movement. The screw 10 moves out of the mounting tube 5. At the same time, the removed display panel 12 is manually supported to facilitate the removal of the screw 10 and the mounting plate 11 and other components.

[0039] When the transparent shell 15 is installed, the first magnetic block 14 and the second magnetic block 16 automatically attract each other, and the transparent shell 15 covers the surface of the LED bead 13, achieving anti-collision protection and light transmission display.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
