Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically to a climbable LED display cabinet frame. Background Technology

[0002] With technological advancements and growing market demand, LED displays have been widely adopted in advertising, stage performances, live sports broadcasts, and many other fields. Large-screen LED displays, with their advantages of high brightness, high contrast, and wide viewing angles, have gradually become important tools for information dissemination and visual presentation. However, as the size of LED displays continues to increase, the need for maintenance and repair is also growing. Traditional maintenance methods typically require external ladders or scaffolding to access the fault point for repairs. This not only increases maintenance time costs but may also make it difficult to find suitable supports for these facilities due to site limitations. Furthermore, each maintenance requires the rearrangement and dismantling of ladders and other auxiliary equipment, significantly reducing the efficiency of maintenance work. While some have suggested installing handles on the LED display cabinet frame as climbing ladders, practical applications have revealed several issues. Firstly, existing LED displays, in pursuit of lightweight design, use thinner materials for the cabinet frame, which may prevent the frame from supporting the weight of maintenance personnel, potentially leading to safety accidents. Secondly, the connection between the handles and the LED display cabinet frame is not always secure, and they are prone to loosening or even falling off during use, also causing safety hazards. Therefore, it is of great significance to design a lightweight, climbable, and highly safe LED display cabinet frame. Utility Model Content

[0003] To address the aforementioned technical challenges, this application provides a climbable LED display cabinet frame, comprising a rectangular frame, a power supply box base plate, and reinforcing ribs. The power supply box base plate is mounted within the frame, and the reinforcing ribs are positioned between the power supply box base plate and the frame. The frame consists of a three-layer structure: an inner ABS plastic layer, a middle honeycomb aluminum plate layer, and an outer stainless steel layer. Two integrally formed spare handles are provided on both sides of the frame. The spare handles are generally U-shaped, comprising a horizontal connecting portion, a supporting portion, and extension portions extending outward from both ends of the horizontal connecting portion. The supporting portion extends outward from the middle of the horizontal connecting portion and is fixedly connected to the reinforcing ribs. The horizontal connecting portion is parallel to the frame, and the extension portions are integrally formed with the frame. The surface of the spare handles is provided with anti-slip textures.

[0004] Preferably, the side of the frame is provided with a pin hole, and a hidden movable positioning pin is provided in the pin hole. The hidden movable positioning pin is provided with a slide groove. The hidden movable positioning pin is provided with a first limiting groove and a second limiting groove at both ends of the slide groove. The fastener can fix the hidden movable positioning pin by cooperating with the first limiting groove or the second limiting groove. The fastener is screwed onto the frame.

[0005] Preferably, soft rubber sleeves are provided at the four top corners of the frame.

[0006] Preferably, the four top corners of the frame are provided with clearance positions, and fixed connectors are provided at the clearance positions, with module corner protectors rotatably connected to the fixed connectors.

[0007] Preferably, the reinforcing rib is also provided with a receiving groove, and a wire harness clip is provided in the receiving groove.

[0008] Preferably, the wire harness clip includes a connecting part and a snap-fit ​​part disposed opposite to it. The snap-fit ​​parts are respectively disposed on both sides of the connecting part and integrally formed with the connecting part, so that the wire harness clip is generally in the shape of a "U". The connecting part is fixed in the receiving groove by fasteners.

[0009] Preferably, the side of the frame is provided with an arc-shaped lock.

[0010] Preferably, the side of the frame is provided with a box handle groove, and the box handle groove is provided with a protrusion integrally formed with the frame. The two ends of the protrusion are provided with connecting holes, and the two ends of the box handle are provided with connecting shafts. The connecting shafts are rotatably connected to the connecting holes. The box handle groove is also provided with a box handle cover. Fasteners pass through the box handle cover and enter the connecting holes to be screwed to the connecting shafts.

[0011] The beneficial effects are as follows: This application improves upon existing climbable LED display cabinet frames. Firstly, the frame border is redesigned with a three-layer structure. The inner layer is made of ABS plastic, which is lightweight, easy to process, and provides cushioning. The middle layer is a honeycomb aluminum plate layer, which significantly improves the rigidity of the entire frame and reduces its weight. The outer layer is made of stainless steel, which greatly enhances the strength of the entire frame and provides excellent corrosion resistance. This design not only meets the lightweight requirements of the entire cabinet frame but also makes it more robust and reliable, improving safety. Furthermore, integrated spare handles are provided on both sides of the frame. When multiple LED display cabinet frames are assembled, these spare handles form a climbing ladder. Maintenance personnel can use this ladder to climb to the location requiring repair without the need for external ladders or tools. Compared to ordinary ladders, this design is not limited by the height of the display screen, reducing the difficulty of repairs. The triangular fixing structure formed by the support, horizontal connection, and extension makes the spare handles more stable, and the anti-slip texture further enhances safety.

[0027] Example

[0028] Please see Figure 1 , Figure 1 This is a schematic diagram of the overall structure of this utility model. This embodiment provides a climbable LED display screen cabinet frame, including a rectangular frame 1, a power supply box base plate 2, and reinforcing ribs 3. The power supply box base plate 2 is mounted inside the frame 1, and the power supply box is detachably installed on the power supply box base plate 2. Reinforcing ribs 3 are located between the power supply box base plate 2 and the frame 1, and there can be multiple reinforcing ribs 3. The reinforcing ribs 3 enhance the load-bearing capacity and strength of the frame 1, eliminate internal stress in the frame 1, reduce deformation, increase toughness, and prevent deformation of the frame 1 due to insufficient strength. The frame 1 consists of a three-layer structure: an inner layer of ABS plastic, a middle layer of honeycomb aluminum plate, and an outer layer of stainless steel. The frame 1 is redesigned with a three-layer structure. The inner layer is made of ABS plastic, which is lightweight, easy to process, and has a cushioning effect. The middle layer of honeycomb aluminum plate significantly improves the rigidity of the entire frame and reduces its weight. The outer layer of stainless steel greatly increases the strength of the entire frame and provides good corrosion resistance. This design not only makes the entire enclosure frame meet the requirements for lightweighting, but also makes the enclosure frame more robust and reliable, thus improving safety.

[0029] See also Figure 1 Please refer to the following: Figure 4 , Figure 4This is an exploded view of the present invention. Two integrally formed spare handles 16 are provided on both sides of the frame 1. The spare handles 16 are generally U-shaped, including a horizontal connecting part 161, a supporting part 162, and extension parts 163 extending outward from both ends of the horizontal connecting part. The supporting part 162 extends outward from the middle of the horizontal connecting part 161 and is fixedly connected to the reinforcing rib 3. The horizontal connecting part 161 is parallel to the frame 1, and the extension parts 163 are integrally formed with the frame 1. The surface of the spare handles 16 is provided with anti-slip textures 164. When multiple LED display cabinet frames are assembled, these spare handles 16 form a ladder that can be climbed. Maintenance personnel can use this ladder to climb to the location requiring repair without the need for external ladders or other tools. Compared to ordinary ladders, this design is not limited by the height of the display screen, reducing the difficulty of repair. The triangular fixing structure formed by the supporting part 162, the horizontal connecting part 161, and the extension parts 163 makes the spare handles 16 more stable overall, and the anti-slip textures 164 greatly improve safety.

[0030] See also Figure 1 Combined again Figure 2 and Figure 3 , Figure 2 This is a cross-sectional view of the concealed movable positioning pin inserted into the pin hole of the frame according to this utility model. Figure 3 This is a cross-sectional view of the concealed movable positioning pin. A pin hole is provided on the side of the frame 1, and a concealed movable positioning pin 11 is provided inside the pin hole. The concealed movable positioning pin 11 has a sliding groove 111. At both ends of the sliding groove 111, the concealed movable positioning pin 11 has a first limiting groove 112 and a second limiting groove 113, respectively. A fastener engages with the first limiting groove 112 or the second limiting groove 113 to fix the concealed movable positioning pin 11. The fastener is screwed onto the frame 1. In this embodiment, screws can be used as the fastener. When the concealed movable positioning pin 11 is needed to position the climbable LED display cabinet frame, simply loosen the fasteners and pull the concealed movable positioning pin 11 out of the pin hole. At this time, the concealed movable positioning pin 11 extends outward from the pin hole towards the frame 1. Then, insert the fastener into the second limiting groove 113 of the concealed movable positioning pin 11 and tighten it to fix the concealed movable positioning pin 11. When the concealed movable positioning pin 11 is not needed to position the climbable LED display cabinet frame, especially when the installation space is limited due to ceilings or other situations, simply loosen the fasteners and press the concealed movable positioning pin 11 back into the pin hole. At this time, the concealed movable positioning pin 11 extends inward from the pin hole towards the frame 1. Then, insert the fastener into the first limiting groove 112 of the concealed movable positioning pin 11 and tighten it to fix the concealed movable positioning pin 11, thus achieving perfect concealment of the positioning pin. (See also...) Figure 1 Combined again Figure 7 , Figure 7This is a schematic diagram of the assembled structure of this utility model. One side of the frame 1 is also provided with a pin 18, and the corresponding position on the other side is provided with a socket 19. When in use, the pin 18 can be directly inserted into the socket 19 to lock it, which can achieve precise positioning without adjustment. It is very simple and practical.

[0031] See also Figure 1 and Figure 4 The four corners of frame 1 are equipped with soft rubber sleeves 12, which act as cushioning to prevent damage to frame 1 during handling. The four corners of frame 1 are also equipped with clearance features 13. (This is combined with...) Figure 5 , Figure 5 This is a schematic diagram of the module corner protector structure. A fixed connector 131 is located at the clearance position 13, and a module corner protector 132 is rotatably connected to the fixed connector 131. The module corner protector 132 can rotate 180° relative to the fixed connector 131. When transporting the LED display screen, the module corner protector 132 can be rotated to the top corner of the module to protect the top corner from damage due to collision. When splicing the LED display screen, the module corner protector 132 can be rotated to avoid being hidden at the clearance position 13. The fixed connector 131 has a first through hole, and the module corner protector 132 has a corresponding second through hole. A pivot pin passes through the first and second through holes to achieve a rotatable connection between the module corner protector 132 and the fixed connector 131.

[0032] See also Figure 4 Combined again Figure 6 , Figure 6 This is a schematic diagram of the wire harness clip structure. The reinforcing rib 3 also has a receiving groove 31, within which the wire harness clip 311 is housed. The wire harness clip 311 includes a connecting part 3111 and opposing engaging parts 3112. The engaging parts 3112 are respectively located on both sides of the connecting part 3111 and integrally formed with the connecting part 3111, making the wire harness clip 311 roughly "U"-shaped. The connecting part 3111 is fixed in the receiving groove 31 by fasteners. This design makes the wire harness clip 311 easy to install and remove, and can fix wire harnesses of different diameters. This wire harness clip 311 does not require CNC machining; it is directly injection molded, resulting in a simple manufacturing process, low cost, and easy disassembly and installation. Screws can be used as the fasteners.

[0033] See also Figure 1 , Figure 4 and Figure 7The frame 1 has an arc-shaped lock 14 on its side, which enables the LED display screen to be spliced ​​in an arc shape. Specifically, one side of the frame 1 has an arc-shaped lock seat 141 with an arc-shaped cavity inside. The arc-shaped lock core is movably disposed in the arc-shaped cavity. The arc-shaped surface of the arc-shaped lock seat 141 has an arc-shaped groove, and at least a part of the arc-shaped lock core extends out of the arc-shaped groove. The arc-shaped lock core slides along the arc-shaped lock seat 141 to adjust the angle of the arc-shaped lock core. The side of the frame 1 of the adjacent climbable LED display screen cabinet frame has a quick-locking tongue 142. The quick-locking tongue 142 cooperates with the arc-shaped lock core to lock it. When the LED display screen needs to be spliced ​​in an arc shape, simply adjust the angle of the arc-shaped lock core, and then insert the quick-locking tongue 142 on the adjacent climbable LED display screen cabinet frame into the arc-shaped lock core of the climbable LED display screen cabinet frame to lock it. Of course, the side of frame 1 is also equipped with a quick lock plate 17. If the LED display screen does not require curved splicing or the curved lock seat 141 is damaged and cannot be used, the quick lock plate 17 can be activated. The two adjacent LED display screen cabinet frames can be locked and fixed by inserting the quick lock tongue 142 into the lock hole of the quick lock plate 17.

[0034] See also Figure 1 and Figure 4 The side of the frame 1 has a box handle groove 15, and the box handle groove 15 has a protrusion 151 integrally formed with the frame. Both ends of the protrusion 151 have connecting holes. Both ends of the box handle 152 have connecting shafts 1521, which are rotatably connected to the connecting holes. The box handle groove 15 also has a box handle cover 153. Fasteners pass through the box handle cover 153 and enter the connecting holes to be screwed onto the connecting shafts 1521. This integrated handle design makes the box handle 152 more securely attached to the frame 1, and also reduces assembly costs and increases safety. The box handle 152 adopts a concealed design and can be stored inside the box handle groove 15 when not in use. When needed, the box handle 152 can be opened from inside the box handle groove 15. The box handle 152 makes handling more comfortable for users. The handle cover 153 can further improve the structural stability on the one hand, and on the other hand, it can achieve waterproof and dustproof protection to prevent internal components such as connecting shaft 1521 and fasteners from being affected by external moisture, dust and other factors, thus reducing their service life.

[0035] In summary, this application improves several parts of the existing climbable LED display cabinet frame. The most significant improvement lies in two aspects: firstly, the frame 1 is redesigned with a three-layer structure, making the entire cabinet frame lightweight and more robust and reliable, thus enhancing safety; secondly, an integrated spare handle 16 is added to the frame of the climbable LED display cabinet frame. This spare handle 16 forms a triangular fixing structure with the support part 162, the horizontal connecting part 161, and the extension part 163, making the overall structure more stable. Combined with the anti-slip texture 164, it provides high safety. When multiple LED display cabinet frames are assembled, these spare handles 16 form a climbing ladder, allowing maintenance personnel to climb to the location requiring repair without the need for external ladders or other tools. In addition, this application adds soft rubber sleeves, module corner protectors, spare handles, and other components. Furthermore, improvements have been made to the arc-shaped lock, cabinet handle, and wire harness buckle, making the improved climbable LED display cabinet frame more convenient and practical.

[0036] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model.
