Description

Technical Field

[0001] This utility model relates to the field of LED screen technology, specifically to an LED screen that facilitates the replacement of displays. Background Technology

[0002] An LED display screen is a display device that uses LED (light-emitting diode) technology as its light source. It displays images, text, and other content through millions of tiny LED beads.

[0003] In practical applications, most LED displays are composed of multiple independent LED modules spliced ​​together. Each module contains a large number of red, green, and blue (RGB) LED beads, and by precisely controlling the brightness of each color bead, a rich and colorful display effect is achieved.

[0004] However, LED displays are highly susceptible to damage from impacts or scratches by hard objects, typically requiring repair or replacement of the damaged LED modules. Currently, most LED modules on the market use plug-in or extrusion-type structures for installation. This method of fixing often requires external tools (such as suction cups) during disassembly, making the process cumbersome. Furthermore, because the modules are stacked, the lower modules bear the weight of the upper modules, resulting in additional pressure and further increasing the risk of damage. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a method for replacing the LED screen of a display, which makes it easier to replace the LED screen body.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for easily replacing LED screens in a display, comprising a frame and several LED screen bodies installed inside the frame. A support frame is fixedly connected to the inner wall of the frame at the end away from the LED screen bodies. A connecting frame is fixedly connected to the side of each of the LED screen bodies near the support frame. An insert plate is fixedly connected to the other side of each of the connecting frames. Several fixing boxes are fixedly connected to the side of the support frame near the connecting frames. The interior of each fixing box has an insertion port. Several insert plates are slidably connected to several insertion ports. A limiting component and an auxiliary pushing component are connected inside each of the insertion ports. The limiting component and the auxiliary pushing component abut against the insert plate.

[0007] Furthermore, the inner wall of the socket has an installation cavity, and the limiting component is located inside the installation cavity.

[0008] Furthermore, the limiting assembly includes a limiting wedge block, a support block, and several push springs. The side wall of the support block is fixedly connected to the inner wall of the mounting cavity, the bottom surface of the support block is fixedly connected to the upper ends of several push springs, the lower ends of several push springs are all fixedly connected to the upper ends of the limiting wedge block, the lower end of the limiting wedge block is slidably connected to the insert plate, and the limiting wedge block slides within the insert and mounting cavity.

[0009] Furthermore, a lifting port is provided through the side of the socket away from the mounting cavity, and the auxiliary pushing component is located in the socket and the lifting port. The end of the auxiliary pushing component located in the socket is also connected to the side wall of the upper end of the limiting wedge block.

[0010] Furthermore, the auxiliary pushing component includes a lifting plate, an electromagnet, and a metal block. The side wall of the electromagnet is fixedly connected to the inner wall of the mounting cavity. One end of the metal block is fixedly connected to the side wall of the upper end of the limiting wedge block, and the bottom surface of the other end of the metal block is fixedly connected to the upper end of the lifting plate. The metal block is aligned in position, and the metal block and the lifting plate slide within the lifting port, the insertion port, and the mounting cavity.

[0011] Furthermore, at least one set of limiting wedges, fixing boxes, limiting components, and auxiliary pushing components are provided between the connecting frames and support frames of several LED screens.

[0012] Furthermore, several sets of limiting wedges, fixing boxes, limiting components, and auxiliary pushing components are evenly distributed between the LED screen and the support frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This type of LED screen is easy to replace. It uses a sliding fit between the insert plate and the socket of the fixing box, combined with the automatic reset function of the limit wedge block under the action of the push spring. The LED screen can be locked after being inserted, without the need for suction cups, screwdrivers or other tools, which is convenient and quick.

[0015] 2. This type of device facilitates the replacement of LED screens. During disassembly, an electromagnet triggers a metal block to move a limit wedge block upwards, while the inclined surface of the lifting plate simultaneously pushes the insert plate outwards, enabling one-click quick replacement and significantly improving maintenance efficiency.

[0016] 3. This type of LED screen facilitates easy replacement of the display screen. Each LED screen is directly connected to the support frame through a connecting frame and a plug plate. There is no stacking load-bearing relationship between modules, avoiding the additional stress damage caused by gravity squeezing of the lower module in traditional designs, and extending the service life of the LED screen.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1-6 A method for facilitating the replacement of LED screens in a display includes a frame 1 and several LED screen bodies 2 installed inside the frame 1. A support frame 3 is fixedly connected to the inner wall of the end of the frame 1 away from the LED screen bodies 2. A connecting frame 4 is fixedly connected to the side of each of the LED screen bodies 2 near the support frame 3. An insert plate 11 is fixedly connected to the other side of each of the connecting frames 4. Several fixing boxes 5 are fixedly connected to the side of the support frame 3 near the connecting frames 4. The interior of each of the fixing boxes 5 has an insertion port 502. The insert plates 11 are slidably connected to the insertion ports 502. Each of the insertion ports 502 has a limiting component and an auxiliary pushing component connected inside. The limiting component and the auxiliary pushing component abut against the insert plate 11.

[0026] like Figures 1 to 6As shown, in this utility model, the easy-to-replace LED screen for display is installed by connecting the frame 1 to a wall, ground, or external bracket using bolts or other fixing structures. Then, several LED screen bodies 2 are installed sequentially within the frame 1. During installation, the connecting frame 4 of the LED screen body 2 is first inserted into the support frame 3 of the frame 1, aligned with the support frame 3. During insertion, the insert plate 11 on the side of the connecting frame 4 away from the LED screen body 2 is aligned with the insertion port 502 of the fixing box 5 on the support frame 3. As the insert plate 11 enters the insertion port 502, the limiting component inside the insertion port 502 is pushed out. As the insert plate 11 continues to be inserted until it is fully inserted into the insertion port 502, the limiting component automatically resets, restricting the insert plate 11 within the insertion port 502 from the side closest to the LED screen body 2. This increases the overall connection stability between the LED screen 2 and the frame 1. Furthermore, the support of the insert plate 11 and the fixing box 5 prevents the upper LED screen 2 from squeezing the lower LED screen 2. Then, connect the power and data cables of the LED screen 2 and the auxiliary pushing component to the external controller. Afterwards, install all the LED screens 2 in the above manner, and after overall debugging, it can be put into formal use. During formal use, if one or more LED screens 2 malfunction, the maintenance personnel only need to release the auxiliary pushing component through the external controller. The auxiliary pushing component will automatically release the limit on the damaged LED screen 2 and push the corresponding LED screen 2 outward a certain distance, making it easier for the maintenance personnel to remove it from the frame 1.

[0027] As a preferred embodiment of this utility model, the inner wall of the socket 502 is provided with an installation cavity 501, and the limiting component is located in the installation cavity 501.

[0028] More specifically, by setting the mounting cavity 501, the limiting component can be stored and supported.

[0029] As a preferred embodiment of this utility model, the limiting component includes a limiting wedge block 9, a support block 12, and a plurality of push springs 8. The side wall of the support block 12 is fixedly connected to the inner wall of the mounting cavity 501, the bottom surface of the support block 12 is fixedly connected to the upper end of the plurality of push springs 8, the lower end of the plurality of push springs 8 is fixedly connected to the upper end of the limiting wedge block 9, the lower end of the limiting wedge block 9 is slidably connected to the insert plate 11, and the limiting wedge block 9 slides within the insert 502 and the mounting cavity 501.

[0030] More specifically, when the insert plate 11 is inserted into the socket 502, the inclined surfaces of the insert plate 11 and the limiting wedge block 9 abut against each other (as shown in the image). Figure 5 and Figure 6Therefore, the insert plate 11 will push the limiting wedge block 9 upward, and the limiting wedge block 9 will compress the push spring 8 as it moves upward. When the insert plate 11 is fully inserted into the socket 502, the limiting wedge block 9 will descend under the action of the push spring 8, so that the straight surfaces of the insert plate 11 and the limiting wedge block 9 can be pressed together to prevent the insert plate 11 and the LED screen body 2 from falling off.

[0031] As a preferred embodiment of this utility model, a lifting port 503 is provided through the side of the socket 502 away from the mounting cavity 501. An auxiliary pushing component is located in the socket 502 and the lifting port 503, and one end of the auxiliary pushing component located in the socket 502 is also connected to the side wall of the upper end of the limiting wedge block 9.

[0032] More specifically, by setting up the lifting port 503, the auxiliary pushing component can be stored and supported.

[0033] As a preferred embodiment of this utility model, the auxiliary pushing component includes a lifting plate 6, an electromagnet 7, and a metal block 10. The side wall of the electromagnet 7 is fixedly connected to the inner wall of the mounting cavity 501. One end of the metal block 10 is fixedly connected to the side wall of the upper end of the limiting wedge block 9, and the bottom surface of the other end of the metal block 10 is fixedly connected to the upper end of the lifting plate 6. The metal block 10 is aligned, and the metal block 10 and the lifting plate 6 slide within the lifting port 503, the insertion port 502, and the mounting cavity 501.

[0034] More specifically, when one or more LED screens 2 are damaged, the maintenance personnel should first turn off the power to all LED screens 2 to avoid danger. Then, the maintenance personnel should turn on the electromagnet 7 on the corresponding LED screen 2. After the electromagnet 7 is energized, it will generate a suction force instantly, which will then pull the metal block 10, the limiting wedge block 9, and the lifting plate 6 upward together (at the same time, the push spring 8 is forcibly compressed). Because the side of the lifting plate 6 near the insertion plate 11 is also inclined, and because of the action of the electromagnet 7, the distance that the metal block 10, the limiting wedge block 9, and the lifting plate 6 rise is much greater than the height that the insertion plate 11 previously pushed the limiting wedge block 9. Therefore, the limiting wedge block 9 will release its restraint on the insertion plate 11. At the same time, the inclined surface of the lifting plate 6 will cooperate with the inclined surface of the insertion plate 11 to push the insertion plate 11 a short distance towards the outside of the insertion port 502, so that the maintenance personnel can easily pull out the damaged LED screen 2.

[0035] As a preferred embodiment of this utility model, at least one set of limiting wedge blocks 9, fixing boxes 5, limiting components and auxiliary pushing components are provided between the connecting frames 4 and support frames 3 of several LED screen bodies 2.

[0036] More specifically, by setting multiple sets, the connection stability between the LED screen 2 and the support frame 3 can be increased.

[0037] As a preferred embodiment of this utility model, several sets of limiting wedge blocks 9, fixing boxes 5, limiting components and auxiliary pushing components are evenly distributed between the LED screen body 2 and the support frame 3.

[0038] More specifically, uniform distribution allows the LED screen body 2 to be subjected to more even force, making it less prone to loosening.

[0039] 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.
