However, during the use of outdoor LED advertising screen cabinets, some insects may collide with the display surface due to the light source, leaving dirt residue that can easily affect the display. Therefore, we propose an outdoor LED advertising screen cabinet. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides an outdoor LED advertising screen enclosure.

[0004] The technical solution adopted by this utility model to solve its technical problem is an outdoor LED advertising screen cabinet, including an advertising screen body. The outer wall surface of the advertising screen body is provided with a groove, and a frame piece for support is fitted and connected to the inner side of the groove. A soft film layer for protecting the LED advertising screen is provided on the inner circumference of the frame piece, and flexible magnetic pieces that are magnetically connected to each other are assembled on the opposite side of the frame piece and the groove.

[0005] The outer periphery of the frame piece has straight holes for limiting positioning, and there are multiple sets of straight holes. The inner side of the groove is fitted with a protruding rod that inserts into the straight hole, and there are multiple sets of protruding rods. The outer periphery of the protruding rod is engaged with an end cap for limiting the frame piece, and the inner periphery of the end cap has U-shaped grooves for limiting positioning, and there are multiple sets of U-shaped grooves. The outer periphery of the protruding rod is integrally constructed with a protrusion that engages with the U-shaped groove, and there are multiple sets of protrusions. The end of the end cap near the frame piece is glued with a sponge ring that abuts against the frame piece.

[0006] By adopting the above technical solution, during the use of outdoor LED advertising screen cabinets, the frame pieces can be easily fitted into the grooves on the outer periphery of the advertising screen body, and the flexible magnetic pieces between the frame pieces and the grooves can be magnetically connected to each other, which facilitates auxiliary positioning of the frame pieces. The soft film layer on the inner periphery of the frame pieces can protect the LED screen on the advertising screen body, thereby reducing the impact of mosquitoes hitting the screen and causing dirt. In addition, the frame pieces are easy to disassemble and clean, making the LED advertising screen cabinet more stable to use.

[0007] When the frame piece is fitted into the groove, the multiple sets of protruding rods in the groove can be inserted into the straight holes on the frame piece. Then, the end cap is removed and inserted into the protruding rods. The protrusions on the outer periphery of the protruding rods can easily fit into the U-shaped grooves on the inner periphery of the end cap. After rotating the end cap, the U-shaped grooves and protrusions can be locked together. The sponge ring on the end cap can push the frame piece back and make the U-shaped grooves and protrusions lock together stably. It can also provide auxiliary positioning for the frame piece, so that the frame piece can be more stably connected to the groove, which facilitates the use of the soft film layer inside the frame piece.

[0008] Specifically, the end cap near the frame has a recessed hole for receiving, and there are multiple sets of recessed holes. A retaining ring for limiting is screwed into the inner side of the recessed hole, and a T-shaped rod that abuts against the frame is slidably installed inside the recessed hole. A compression spring for pushing the T-shaped rod to move is assembled between the T-shaped rod and the recessed hole.

[0009] By adopting the above technical solution, after the end cap and the protruding rod are engaged, the compression spring in the concave hole of the end cap can easily push the T-shaped rod, allowing one end of the T-shaped rod to pass through the retaining ring and abut against the frame piece. This facilitates the provision of a counter-pushing force between the end cap and the protruding rod, enabling the end cap to engage more stably with the protruding rod. At the same time, it facilitates the end cap to limit the position of the frame piece. Subsequently, simply press the end cap firmly and rotate it in the opposite direction to allow the protrusion to slide along the U-shaped groove. Then, the end cap and the protruding rod can be disassembled, facilitating the subsequent disassembly, cleaning, or replacement of the frame piece. This allows the soft film layer to stably protect the main body of the advertising screen and facilitates its use.

[0010] Specifically, the inner circumferential surface of the retaining ring is provided with an arc-shaped groove for rotation, and there are multiple sets of arc-shaped grooves.

[0011] By adopting the above technical solution, the arc-shaped groove on the inner circumference of the retaining ring makes it easier to disassemble and assemble the retaining ring, and facilitates the maintenance or replacement of the structure in the concave hole.

[0012] Specifically, a ball bearing is provided at the end of the T-shaped rod away from the concave hole.

[0013] By adopting the above technical solution, the ball bearings on the outer end of the T-shaped rod can roll easily, thereby reducing the damage caused by friction between the T-shaped rod and the frame.

[0014] Specifically, a leak-proof film frame is adhered to the side of the frame piece near the groove.

[0015] By adopting the above technical solution, the film frame can improve the tightness of the connection between the frame and the groove, thereby reducing the possibility of dust, debris or insects seeping in, and improving the protective effect of the soft film layer on the main body of the advertising screen.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of grooves, frames, soft film layers, and flexible magnetic sheets, allows the frames to be easily fitted into the grooves on the outer periphery of the advertising screen body during the use of outdoor LED advertising screen cabinets. The flexible magnetic sheets between the frames and the grooves can be magnetically connected to each other, which facilitates auxiliary positioning of the frames. The soft film layer on the inner periphery of the frames can protect the LED screen on the advertising screen body, thereby reducing the impact of insects hitting the screen and causing dirt. In addition, the frames are easy to disassemble and clean, making the LED advertising screen cabinet more stable to use.

[0018] 2. The technical solution of this application, through the design of straight holes, protruding rods, end caps, arc-shaped blocks, U-shaped grooves, and sponge rings, allows multiple sets of protruding rods in the groove to interlock with the straight holes on the frame piece when the frame piece is fitted into the groove. Then, the end cap is removed and interlocked with the protruding rods. The protrusions on the outer periphery of the protruding rods can easily fit into the U-shaped grooves on the inner periphery of the end cap. After rotating the end cap, the U-shaped grooves and protrusions can be locked together. The sponge ring on the end cap can push the frame piece back and make the U-shaped grooves stably lock together with the protrusions, and can also provide auxiliary positioning for the frame piece, so that the frame piece can be more stably connected to the groove, facilitating the use of the soft film layer inside the frame piece.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3 This utility model provides a technical solution: an outdoor LED advertising screen housing, including an advertising screen body 1, a groove 2 is provided on the outer wall surface of the advertising screen body 1, and a frame piece 3 for support is fitted and connected to the inner side of the groove 2. A soft film layer 4 for LED advertising screen protection is provided on the inner circumference of the frame piece 3, and flexible magnetic pieces 5 that are magnetically connected to each other are assembled on the opposite side of the frame piece 3 and the groove 2. A straight hole 6 for limiting is opened on the outer circumference of the frame piece 3, and there are multiple sets of straight holes 6. A protruding rod 7 that is inserted into the straight hole 6 is assembled on the inner side of the groove 2, and there are multiple sets of protruding rods 7. An end cap 8 for limiting the frame piece 3 is snapped on the outer circumference of the protruding rod 7, and a U-shaped groove 10 for limiting is opened on the inner circumference of the end cap 8, and there are multiple sets of U-shaped grooves 10. A protrusion 9 that is snapped and connected to the U-shaped groove 10 is integrally constructed on the outer circumference of the protruding rod 7, and there are multiple sets of protrusions 9. A sponge ring 11 that abuts against the frame piece 3 is glued to the end of the end cap 8 near the frame piece 3.

[0026] When using the outdoor LED advertising screen cabinet, the frame piece 3 can be easily fitted into the groove 2 on the outer periphery of the advertising screen body 1, and the flexible magnetic piece 5 between the frame piece 3 and the groove 2 can be magnetically connected to each other, which facilitates the auxiliary positioning of the frame piece 3, and allows the soft film layer 4 on the inner periphery of the frame piece 3 to protect the LED screen on the advertising screen body 1, thereby reducing the impact of mosquitoes hitting the screen and causing dirt. In addition, the frame piece 3 is easy to disassemble and clean, making the LED advertising screen cabinet more stable to use.

[0027] When the frame piece 3 is fitted into the groove 2, the multiple sets of protruding rods 7 in the groove 2 can be inserted into the straight holes 6 on the frame piece 3 respectively. Then, the end cap 8 is taken out and inserted into the protruding rods 7. The protrusions 9 on the outer periphery of the protruding rods 7 can easily fit into the U-shaped grooves 10 on the inner periphery of the end cap 8. After rotating the end cap 8, the U-shaped grooves 10 and the protrusions 9 can be engaged with each other. The sponge ring 11 on the end cap 8 can push the frame piece 3 back and make the U-shaped grooves 10 stably engage with the protrusions 9. It can also provide auxiliary positioning for the frame piece 3, so that the frame piece 3 can be more stably connected to the groove 2, which facilitates the use of the soft film layer 4 inside the frame piece 3.

[0028] like Figure 3 As shown, the end cap 8 has a recessed hole 12 for receiving near the frame piece 3, and there are multiple sets of recessed holes 12. A retaining ring 13 for limiting is screwed into the inner side of the recessed hole 12, and a T-shaped rod 14 that abuts against the frame piece 3 is slidably installed inside the recessed hole 12. A compression spring 15 for pushing the T-shaped rod 14 to move is assembled between the T-shaped rod 14 and the recessed hole 12.

[0029] In use, after the end cap 8 and the protruding rod 7 are engaged, the compression spring 15 in the recess 12 on the end cap 8 can easily push the T-shaped rod 14, allowing one end of the T-shaped rod 14 to pass through the retaining ring 13 and abut against the frame piece 3. This facilitates the provision of a counter-pushing force between the end cap 8 and the protruding rod 7, enabling the end cap 8 to engage more stably with the protruding rod 7. It also helps the end cap 8 to limit the position of the frame piece 3. Subsequently, simply press the end cap 8 firmly and rotate it in the opposite direction to allow the protrusion 9 to slide along the U-shaped groove 10. Then, the end cap 8 and the protruding rod 7 can be disassembled, facilitating the subsequent disassembly, cleaning, or replacement of the frame piece 3. This allows the soft film layer 4 to stably protect the main body 1 of the advertising screen and facilitate its use.

[0030] like Figure 3 As shown, the inner circumferential surface of the retaining ring 13 is provided with an arc-shaped groove 18 for rotation, and there are multiple sets of arc-shaped grooves 18.

[0031] When in use, the arc-shaped groove 18 on the inner circumference of the retaining ring 13 makes it easier to disassemble and assemble the retaining ring 13, and facilitates the maintenance or replacement of the structure in the concave hole 12.

[0032] like Figure 1 and Figure 3 As shown, a ball bearing 16 is provided at the end of the T-shaped rod 14 away from the concave hole 12.

[0033] During use, the ball bearings 16 on the outer end of the T-shaped rod 14 are easy to roll, thereby reducing the damage caused by friction between the T-shaped rod 14 and the frame piece 3.

[0034] like Figure 2 As shown, a leak-proof film frame 17 is glued to the side of the frame 3 near the groove 2.

[0035] When in use, the film frame 17 facilitates the tightness of the connection between the frame 3 and the groove 2, thereby reducing the possibility of dust, debris or insects seeping into it, and improving the protective effect of the soft film layer 4 on the advertising screen body 1.

[0036] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. During the use of the outdoor LED advertising screen cabinet, the frame piece 3 can be easily fitted into the groove 2 on the outer periphery of the advertising screen body 1. The flexible magnetic strip 5 between the frame piece 3 and the groove 2 can be magnetically connected to each other, facilitating auxiliary positioning of the frame piece 3. This also allows the soft film layer 4 on the inner periphery of the frame piece 3 to protect the LED screen on the advertising screen body 1, thereby reducing the impact of insects hitting the screen and causing dirt. The frame piece 3 is easy to disassemble and clean, making the LED advertising screen cabinet more stable to use. Simultaneously, when the frame piece 3 is fitted into the groove 2, the multiple sets of protruding rods 7 in the groove 2 can be inserted into the straight holes 6 on the frame piece 3. Then, take out the end cap 8 and insert it into the protruding rods 7. The protrusions 9 on the outer periphery of the protruding rods 7 can easily fit into the U-shaped groove 10 on the inner periphery of the end cap 8. After rotating the end cap 8, the U-shaped groove 10 and the protrusions 9 can be locked together. The sponge ring 11 on the cover 8 can push the frame piece 3 back and make the U-shaped groove 10 stably engage with the protrusion 9, and can also provide auxiliary positioning for the frame piece 3, so that the frame piece 3 can be more stably connected with the groove 2, which facilitates the use of the soft film layer 4 inside the frame piece 3. Moreover, when the end cover 8 and the protrusion 7 are engaged, the compression spring 15 in the recess 12 on the end cover 8 can easily push the T-shaped rod 14, so that one end of the T-shaped rod 14 can pass through the retaining ring 13 and abut against the frame piece 3, thereby facilitating auxiliary positioning. The end cap 8 provides a counter-thrust force between the end cap 8 and the protrusion 7, enabling the end cap 8 to more stably engage with the protrusion 7. It also facilitates the end cap 8 in limiting the position of the frame piece 3. Subsequently, simply press the end cap 8 firmly and rotate it in the opposite direction to allow the protrusion 9 to slide along the U-shaped groove 10, and then the end cap 8 and the protrusion 7 can be disassembled. This makes it convenient to disassemble, clean, or replace the frame piece 3, ensuring that the soft film layer 4 can stably protect the main body 1 of the advertising screen and facilitate its use.
