Description

Technical Field

[0001] This utility model belongs to the field of display screen technology, and in particular relates to a quick disassembly mechanism for display screen back panel. Background Technology

[0002] According to the published patent CN220773881U, an LED display screen that is easy to disassemble quickly includes a display screen shell, a display screen body, and a display screen back plate. The display screen body is connected inside the display screen shell, and the display screen back plate is mated to the outer wall of the display screen shell. Furthermore, heat dissipation holes are provided on both sides of the outer wall of the display screen shell. This solves the problem of needing to repeatedly turn bolts with screwdrivers or other tools to disassemble and replace the display screen, which is cumbersome and causes wear on the bolt structure. Over time, the bolts may strip or become stuck, affecting the use of the LED display screen. However, it still has the following shortcomings: The aforementioned device achieves rapid disassembly upon completion. However, the rapid disassembly structure in this device is relatively simple, which may cause the back panel to lose sufficient support or stability during disassembly or long-term use. The back panel is easily affected by external forces, which may cause deformation or damage to the display screen casing, thereby affecting the overall quality and durability of the product. Therefore, we propose a rapid disassembly mechanism for the display screen back panel. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-release mechanism for the back panel of a display screen. By combining the quick-release mechanism with the protective mechanism, the above-mentioned device achieves the effect of quick disassembly upon completion. However, the quick-release structure in this device is relatively simple, which may cause the back panel to lose sufficient support or stability during disassembly or long-term use. The back panel is easily affected by external forces, which may cause deformation or damage to the display screen casing, thereby affecting the overall quality and durability of the product.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a quick-release mechanism for a display screen back panel, including a fixed frame, a display screen is fixedly connected to the inner wall of the fixed frame, and a quick-release mechanism is provided on the outer wall of the display screen. The quick-release mechanism includes an outer frame, the outer wall of which is fixedly connected to the outer wall of the display screen. The outer wall of the outer frame has several positioning slots. The inner wall of the outer frame is fixedly connected to several plug-in boxes, each with its own slot. The outer wall of the outer frame contacts a back plate, the outer wall of the back plate is inserted into the inner walls of the positioning slots, and the outer wall of the back plate is fixedly connected to several plug-in blocks. The outer walls of these plug-in blocks are inserted into the inner walls of the plug-in boxes, and each plug-in block has a T-slot on its inner wall. The inner wall of the back plate is screwed with several threaded rods, the outer walls of which are slidably connected to the inner walls of the T-slots. The outer wall of the plug-in boxes is provided with a protective mechanism.

[0005] Furthermore, each of the bottom outer walls of the screws is rotatably connected to an extrusion block, each of the inner walls of the T-slots is fixedly connected to a fixing plate, and each of the inner walls of the fixing plates is slidably connected to a limit sliding shaft.

[0006] Furthermore, the inner walls of several of the plug-in blocks are provided with sliding grooves, one end of several of the limiting sliding shafts near the fixed plate is slidably connected to the outer wall of the sliding groove, the outer wall of the end of several of the limiting sliding shafts away from the fixed plate is in contact with the outer wall of the extrusion block, and the outer wall of several of the limiting sliding shafts is sleeved with springs.

[0007] Furthermore, the protective mechanism includes several support plates, the outer walls of the several support plates are fixedly connected to the outer wall of the plug-in box, the outer wall of the back plate is fixedly connected to several fixing brackets, the outer walls of the several support plates are in contact with the protective plate, and the outer wall of the protective plate away from the support plates is fixedly connected to several fixing blocks.

[0008] Furthermore, each of the inner walls of the fixed blocks is fixedly connected to a fixed shaft, and each of the outer walls of the fixed shafts is fitted with a spring.

[0009] Furthermore, each of the fixed shafts has a sliding plate slidably connected to its outer wall, and each of the sliding plates has a fixed frame fixedly connected to its outer wall on the side away from the second spring.

[0011] Furthermore, a damper is fixedly connected to the outer wall of the protective plate, and the outer wall of the damper at the end away from the protective plate is fixedly connected to the outer wall of the back plate.

[0012] This utility model has the following beneficial effects: 1. This utility model incorporates a limiting slide shaft. When the limiting slide shaft is in use, it simultaneously releases the pressure on the spring. When the spring is no longer compressed, it rebounds, and the rebound force drives the limiting slide shaft to reset. After resetting, the limiting slide shaft retracts one end, which was originally in the slot, into the insertion block, thus releasing the limiting effect on the insertion block and consequently releasing the fixing limitation on the back panel. This allows the back panel to be removed quickly, greatly simplifying the display screen maintenance process. This not only reduces downtime but also improves maintenance efficiency.

[0013] 2. This utility model incorporates a backplate. When the backplate moves, it drives the connecting rod to rotate via the second fixing frame. When the connecting rod rotates, it drives the slide plate to move on the fixed shaft via the fixing frame. When the slide plate moves, the second spring is compressed. When the second spring is compressed, it contracts. During the contraction process, the elastic potential energy released by the spring cancels out the impact force. When the backplate moves, it also compresses the damper simultaneously. At this time, the damper also cancels out part of the impact force. This achieves the effect of protecting the display screen, reducing damage caused by drops or accidental impacts, protecting the internal electronic components and display panel of the device, and avoiding functional failure or permanent damage caused by impact.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6 As shown, this utility model is a quick-release mechanism for the back panel of a display screen, including a fixing frame 1. The inner wall of the fixing frame 1 is fixedly connected to the display screen 101. The fixing frame 1 fixes the display screen 101 to prevent it from falling during use. The outer wall of the display screen 101 is provided with a quick-release mechanism 2. The quick-release mechanism 2 includes an outer frame 201, the outer wall of which is fixedly connected to the outer wall of the display screen 101. The outer wall of the outer frame 201 has several positioning slots 202, which serve a positioning function during installation, facilitating subsequent installation. The inner wall of the outer frame 201 is fixedly connected to several connector boxes 203, each with a slot 204 on its inner wall. These slots 204 are for engaging with subsequent components, facilitating subsequent installation and fixation. The outer wall of the outer frame 201 contacts a back plate 205, whose outer wall engages with the inner walls of the positioning slots 202. A number of plug-in blocks 206 are fixedly connected to the outer wall of the plate 205. The outer walls of the plug-in blocks 206 are all plugged into the inner wall of the plug box 203. The back plate 205 can be quickly installed by connecting the plug-in blocks 206 on the back plate 205 to the plug box 203. The inner walls of the plug-in blocks 206 are provided with T-slots 207. A number of threaded rods 208 are screwed to the inner wall of the back plate 205. The outer walls of the threaded rods 208 are slidably connected to the inner walls of the T-slots 207. When the threaded rods 208 start to rotate, they will rotate in the T-slots 207 and move upward through the back plate 205. The outer wall of the plug box 203 is provided with a protective mechanism 3. Several lead screws 208 are rotatably connected to the outer bottom walls of their respective screws 208. Several T-slots 207 are fixedly connected to the inner walls of their respective T-slots 207. When the lead screws 208 begin to move upward, they synchronously drive the extrusion blocks 209 to move upward. Several fixed plates 210 are slidably connected to their inner walls by limiting slide shafts 211. Several plug-in blocks 206 have sliding grooves 212 on their inner walls. The ends of the limiting slide shafts 211 closest to the fixed plates 210 are slidably connected to the outer walls of the sliding grooves 212. When the extrusion blocks 209 cease to extrude force on the limiting slide shafts 211, they release their limiting effect. The outer walls of the ends of the limiting slide shafts 211 furthest from the fixed plates 210 then contact the outer walls of the extrusion blocks 209. A spring 213 is fitted on the outer wall of several limiting slide shafts 211. When the spring 213 is no longer compressed, it will rebound. At this time, the rebound force of the spring 213 will drive the limiting slide shaft 211 to quickly reset. The protective mechanism 3 includes several support plates 301. The outer wall of the several support plates 301 is fixedly connected to the outer wall of the plug box 203. Several fixing brackets 309 are fixedly connected to the outer wall of the back plate 205. The outer wall of the several support plates 301 is in contact with the protective plate 302. The support plates 301 are used to support and fix the protective plate 302, thereby preventing the protective plate 302 from falling off during use. Several fixing blocks 303 are fixedly connected to the outer wall of the protective plate 302 away from the support plates 301. A number of fixed blocks 303 are fixedly connected to fixed shafts 304 on their inner walls. A second spring 305 is fitted onto the outer wall of each fixed shaft 304. The second spring 305 uses its own elastic potential energy to counteract the transmitted impact force. A sliding plate 306 is slidably connected to the outer wall of each fixed shaft 304. A fixed frame 307 is fixedly connected to the outer wall of each sliding plate 306 on the side away from the second spring 305. A connecting rod 308 is rotatably connected to the outer wall of each fixed frame 307. When the connecting rod 308 starts to rotate, it will pass through the fixed frame 307. The slide plate 306 moves on the fixed shaft 304. When the slide plate 306 starts to move, the spring 305 will compress it. The inner wall of the end of several connecting rods 308 away from the fixed frame 307 is rotatably connected to the outer wall of the fixed frame 309. The outer wall of the protective plate 302 is fixedly connected to the damper 310. When the back plate 205 starts to move, it will also compress the damper 310 synchronously. At this time, the damper 310 will also offset part of the impact force. The outer wall of the end of the damper 310 away from the protective plate 302 is fixedly connected to the outer wall of the back plate 205.

[0020] One specific application of this embodiment is: When the operator needs to use the equipment, first rotate the lead screw 208. As the lead screw 208 rotates, it moves upwards, causing the pressing block 209 to move upwards as well. After moving a certain distance, it disengages from one end of the limiting slide shaft 211. At this point, the pressing block 209 releases its pressure on the limiting slide shaft 211, and the limiting slide shaft 211 simultaneously releases its pressure on the spring 213. When the spring 213 is no longer compressed, it rebounds. The rebound force of the spring 213 then resets the limiting slide shaft 211. After resetting, the limiting slide shaft 211 retracts its end, which was originally in the slot 204, into the insertion block 206, thus releasing the limiting position on the insertion block 206 and consequently releasing the fixing limit on the back plate 205. The back plate 205 can then be removed. To achieve the effect of quick disassembly of the back panel 205, when the device falls, the back panel 205 will move due to the impact force when it contacts the ground. When the back panel 205 starts to move, it will drive the connecting rod 308 to rotate through the second fixing frame 309. When the connecting rod 308 starts to rotate, it will drive the sliding plate 306 to move on the fixed shaft 304 through the fixing frame 307. When the sliding plate 306 starts to move, the second spring 305 will be squeezed. When the second spring 305 is squeezed, it will contract. During the contraction process, the elastic potential energy released by itself will cancel out the impact force. When the back panel 205 starts to move, it will also squeeze the damper 310 at the same time. At this time, the damper 310 will also offset part of the impact force. At this time, the display screen 101 is protected, preventing the impact force from damaging the display screen 101 and its internal electronic components.
