Technical Field

[0001] This utility model relates to the field of LED display technology, and specifically to an LED display with a waterproof and anti-oxidation function for the back socket. Background Technology

[0002] An LED display screen is a large electronic display composed of countless light-emitting diodes (LEDs) as pixels. By controlling the color and brightness of these "little bulbs," any dynamic or static image, such as text, pictures, and videos, can be created.

[0003] Currently, LED displays have a port compartment on the back, which contains multiple USB ports, audio jacks, etc. However, the current port compartments lack a sealed structure. These jacks are rarely used in actual use, so they are exposed to the outside environment for a long time. External moisture and oxygen can easily come into contact with them, causing oxidation and corrosion of the interfaces, which affects their service life. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an LED display screen with waterproof and anti-oxidation function for the back socket, which can cover and seal the port compartment through the cover plate, so as to solve the problem mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: an LED display screen with waterproof and anti-oxidation function for the back insertion hole, including a cover plate covering the port compartment on the back of the LED display screen body. The port compartment on the back of the LED display screen body is provided with positioning grooves on both sides vertically. Positioning strips are installed on both sides of the cover plate and are slidably set in the positioning grooves. A thickened part is protruding on the outer side of the cover plate. A storage groove is formed by recessing the inner side of the cover plate opposite to the thickened part. One end of the storage groove extends into the thickened part. A recessed groove communicating with the storage groove is provided vertically on the bottom surface of the storage groove. A frame is slidably installed in the recessed groove. A part of the frame extends into the opening of the storage groove. A filter screen is installed inside the frame.

[0006] As a preferred technical solution, the outer side of the cover plate is provided with a through hole at the lowest point of the port compartment. A positioning rod is provided in the through hole. One end of the positioning rod extends into the interior of the port compartment and contacts the bottom surface of the port compartment. The other end extends to the outside and is fitted with a handle. A first compression spring is fitted on the exposed section of the positioning rod. One end of the first compression spring is installed on the cover plate and the other end is installed on the handle.

[0007] As a preferred technical solution, a limiting plate is installed on the back of the LED display body above the port compartment, with one end of the cover plate abutting against the limiting plate.

[0008] As a preferred technical solution, both the positioning groove and the positioning strip have an "L" shaped cross-section.

[0009] As a preferred technical solution, the inner side of the cover plate is fitted to the back of the LED display screen body.

[0010] As a preferred technical solution, the two sides of the recessed groove are provided with vertical sliding grooves, one end of each sliding groove extends into the storage groove, and the two sides of the frame protrude to form sliding strips, which are slidably disposed in the sliding grooves.

[0011] As a preferred technical solution, multiple second compression springs are installed on the bottom surface of the relief groove, and the other end of each second compression spring is installed on the frame.

[0012] As a preferred technical solution, the inner side of the frame does not protrude beyond the inner side of the cover plate.

[0013] The beneficial effects of this utility model are as follows: This utility model has a simple structure and the cover plate is independently set, which facilitates disassembly and assembly. The desiccant can be put into the storage slot by pressing down the frame from the outside. After the frame is released, the frame can rebound by the second compression spring, thereby covering the opening of the storage slot, preventing the desiccant from falling out, and also facilitating the replacement of the desiccant. The cover plate can slide along the positioning groove and be assembled on the back of the LED display screen body. After contacting the limiting plate, the positioning rod can be inserted into the bottom of the port compartment, thereby positioning the cover plate up and down to ensure the stability of the installation. The cover plate and desiccant can make the back socket waterproof and anti-oxidation, increasing the service life. Attached Figure Description

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an LED display screen with waterproof and anti-oxidation functions for the back insertion hole. It includes a cover plate 2 that covers the port compartment 8 on the back of the LED display screen body 1. The port compartment 8 on the back of the LED display screen body 1 has vertically arranged positioning grooves 3 on both sides. Positioning strips 10 are installed on both sides of the cover plate 2. The positioning strips 10 are slidably arranged in the positioning grooves 3. A thickened part 6 is protruding on the outer side of the cover plate 2. A storage groove 11 is recessed on the inner side of the cover plate 2 opposite to the thickened part 6. One end of the storage groove 11 extends into the thickened part 6. A relief groove 14 is vertically arranged on the bottom surface of the storage groove 11 and communicates with the storage groove 11. A frame 12 is slidably installed in the relief groove 14. A part of the frame 12 extends into the opening of the storage groove 11. A filter screen 13 is installed inside the frame 12.

[0021] In this embodiment, a through hole 16 is provided on the outer side of the cover plate 2 at the lowest point of the port compartment 8. A positioning rod 9 is provided in the through hole 16. One end of the positioning rod 9 extends into the interior of the port compartment 8 and contacts the bottom surface of the port compartment 8. The other end extends to the outside and is fitted with a handle 5. A first compression spring 4 is sleeved on the exposed section of the positioning rod 9. One end of the first compression spring 4 is installed on the cover plate 2 and the other end is installed on the handle 5.

[0022] In this embodiment, a limiting plate 7 is installed on the back of the LED display body 1 above the port compartment 8, and one end of the cover plate 2 is set to abut against the limiting plate 7.

[0023] In this embodiment, the cross-sections of the positioning groove 3 and the positioning strip 10 are both set in an "L" shape. The positioning groove and the positioning strip can position the cover plate, preventing the cover plate from falling out directly.

[0024] In this embodiment, the inner side of the cover plate 2 is fitted to the back of the LED display body 1. A rubber layer can be adhered to the inner side of the cover plate to increase the sealing between the cover plate and the back of the LED display body.

[0025] In this embodiment, sliding grooves are provided vertically on both sides of the relief groove 14, and one end of each sliding groove extends into the storage groove 11. Sliding strips are formed by protrusions on both sides of the frame 12. The sliding strips are slidably disposed in the sliding grooves. The sliding grooves and sliding strips can restrict the frame in the relief groove and the storage groove, preventing it from falling out on its own.

[0026] In this embodiment, a plurality of second compression springs 15 are installed on the bottom surface of the recess 14, and the other end of each second compression spring 15 is installed on the frame 12.

[0027] In this embodiment, the inner side of the frame 12 does not protrude from the inner side of the cover plate 2, which avoids friction between the frame and the back of the LED display body, thus preventing the frame from shifting downwards when the cover plate moves along the positioning groove.

[0028] Working principle: The cover plate 2 slides with the positioning groove 3 on the back of the LED display body 1 through the positioning strips 10 on both sides, so that the inner side of the cover plate 2 fits tightly with the back of the LED display body 1, completely covering the port compartment 8. During installation, the positioning rod is pulled outward by the grip rod. After the upper end of the cover plate 2 abuts against the limiting plate 7, the rebound of the first compression spring can drive the positioning rod to insert into the bottom of the port compartment 8, thereby fixing it from top to bottom, ensuring that the cover plate 2 is installed firmly, forming a sealed environment, and isolating external moisture and oxygen.

[0029] After the positioning rod is pulled out, the cover plate can be removed from the LED display body along the positioning groove. After disassembly, the frame can be pressed down, causing the frame 12 to slide backward and open the storage slot 11 to facilitate the insertion or replacement of the desiccant. After the frame 12 is released, the second compression spring 15 rebounds and pushes the frame 12 back to its original position. The filter screen 13 prevents the desiccant from falling off, while allowing air circulation so that the desiccant can continuously absorb moisture in the port compartment 8 and prevent oxidation and corrosion of the socket.

[0030] Furthermore, the cover plate can be replaced independently after it is damaged.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
