Description

Technical Field

[0001] This utility model relates to the field of LED triangular display technology, and more specifically, to an LED triangular display. Background Technology

[0002] In the field of LED triangular displays, heat dissipation performance and installation stability are key factors affecting the service life and display effect of the equipment. However, LED triangular displays on the market still have many technical defects in practical applications. These problems not only affect the normal operation of the display, but may also reduce the service life and maintenance efficiency of the equipment.

[0003] The primary problem is the unreasonable design of the heat dissipation system. Existing LED triangular displays generally use natural heat dissipation, which has significant shortcomings: First, LED display units generate a large amount of heat during long-term operation, especially under high-brightness display conditions, where heat accumulation is even more pronounced; second, natural heat dissipation relies on natural airflow for heat exchange, resulting in low heat dissipation efficiency and failing to meet the heat dissipation requirements of continuous operation; third, heat accumulation leads to increased device temperature, affecting not only display performance but also accelerating LED device aging and shortening its lifespan. Furthermore, in enclosed or poorly ventilated environments, the effectiveness of natural heat dissipation is even more limited, potentially causing the device to overheat and trigger protection mechanisms, thus affecting normal operation.

[0004] Even more problematic is the serious flaw in the installation structure design. In existing technologies, both the display screen and the cooling fan need to be mounted on the mounting frame, but this installation method has many inconveniences: First, traditional installation methods usually require a large number of screws and fasteners, making the installation process cumbersome and time-consuming; second, the limited operating space during installation and disassembly increases the difficulty of maintenance; third, the need for specialized tools for complex installation steps also increases the risk of operational errors, which may affect the installation accuracy and stability of the equipment. Especially when emergency maintenance is required, the cumbersome disassembly and assembly process will prolong the equipment's downtime and affect its efficiency.

[0005] Most seriously, even though some improved equipment adopts quick-release structures, their designs still have significant shortcomings. While these quick-release devices simplify the replacement process of displays and fans to some extent, their structures are too simple and lack necessary shock-resistant and anti-loosening designs. In actual use, the equipment may be affected by various external factors, such as environmental vibration and wind impact. The simple fixing structure is difficult to resist these external interferences, which can easily lead to loosening and misalignment of the installation structure, or even cause the display or fan to fall off. This instability not only affects the display effect but may also cause equipment damage and safety hazards. At the same time, the instability of the installation structure will increase the maintenance frequency of the equipment. Maintenance personnel need to regularly check and adjust the fixing status, which increases maintenance costs and workload. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides an LED triangular display screen, which has the following beneficial effects:

[0019] 1. The heat dissipation device constructs a highly efficient active cooling system through the scientific combination of a fan, air intake slots, and filter plates. The detachable design of the fan facilitates maintenance and replacement, the reasonable layout of multiple air intake slots ensures sufficient air intake, and the filtration function of the filter plates effectively blocks dust and other impurities from entering the equipment. This active cooling solution not only significantly improves heat dissipation efficiency and avoids problems such as the equipment's display effect being affected or its lifespan being shortened due to excessive temperature, but also facilitates regular cleaning and maintenance through the detachable design of the filter plates, ensuring long-term stable heat dissipation.

[0020] 2. The quick-lock device achieves rapid installation and disassembly between the display screen and the mounting frame through the precise cooperation of the locking sleeve, control sleeve, control block, locking block, locking plate, movable shaft, movable groove, and control groove. The detachable design of the locking sleeve and locking rod, combined with the precise guidance of the slide bar and slide groove, ensures a smooth and accurate installation process. The rotational design of the control sleeve, in conjunction with the variable diameter structure of the control groove and control block, enables the rapid release and reset of the locking block. The flexible rotation of the locking plate in the movable groove through the movable shaft, combined with the elasticity of the tension spring, ensures the reliability of the locking mechanism. This design greatly simplifies the installation and disassembly process of the display screen and reduces maintenance time.

[0021] 3. The locking mechanism, through the organic combination of a release plate, locking sleeve, longitudinal plate, transverse plate, release groove, locking rod, connecting spring, and locking slot, constructs a reliable secondary locking system. The linkage design of the release plate and locking sleeve, through the cooperation of the longitudinal and transverse plates, achieves precise control of the locking state. The rotation design of the release groove, in conjunction with the sliding mechanism of the transverse plate, ensures smooth locking. The meshing structure of multiple locking rods and locking slots, through the elastic action of the connecting spring, provides stable locking force. The rounded corner design of the locking rod ends and the inner wall of the locking slot not only improves the smoothness of operation but also reduces wear on parts. The preload applied by the spring to the locking sleeve further enhances the reliability of the locking structure. This multi-locking mechanism effectively prevents the display screen from loosening and displacement due to external vibration during use, greatly improving the stability and safety of the equipment.

[0032] Please see Figures 1-6An LED triangular display screen includes a display screen 1. A mounting frame 2 is detachably mounted on one side of the display screen 1. A heat dissipation device is mounted on one side of the mounting frame 2. A quick-locking device is mounted on one side of the mounting frame 2. The quick-locking device includes a locking sleeve 3, a control sleeve 4, a control block 5, a locking block 6, a locking plate 7, a movable shaft 8, a movable groove 9, and a control groove 10. The locking sleeve 3 is detachably fitted onto the outside of a locking rod 40. The control sleeve 4 is rotatably mounted on the outside of the locking sleeve 3. The control block 5 slides in the control groove 10. The locking block 6 is fixedly connected to one side of the control block 5. The locking plate 7 is rotatably mounted in the movable groove 9 via the movable shaft 8. The movable groove 9 is located on the outside of the locking rod 40. The control groove 10 is located in the control sleeve 4. Both the control groove 10 and the control block 5 are variable... The locking mechanism is designed with a diameter structure and includes a locking mechanism on the outside of the locking sleeve 3. The locking mechanism includes a release plate 11, a locking sleeve 12, a longitudinal plate 13, a transverse plate 14, a release groove 15, a locking rod 16, a connecting spring 17, and a locking groove 18. The release plate 11 is rotatably mounted on the outside of the locking sleeve 3, the locking sleeve 12 is slidably mounted on the outside of the locking sleeve 3, the longitudinal plate 13 is fixedly connected to one side of the locking sleeve 12, three transverse plates 14 are fixedly connected to one side of the longitudinal plate 13, the release groove 15 is opened on the release plate 11, multiple locking rods 16 are slidably mounted on the side wall of the control sleeve 4, and multiple locking grooves 18 are opened on the outer wall of the locking sleeve 3. One end of the locking rod 16 is connected to the outer wall of the control sleeve 4 through the connecting spring 17, and the other end of the locking rod 16 is inserted into the locking groove 18.

[0033] The heat dissipation device includes an air intake slot 19, a fan 20, and a filter plate 21. The fan 20 is detachably mounted on the mounting frame 2. Multiple air intake slots 19 are formed on the side wall of the mounting frame 2. The filter plate 21 is detachably disposed inside the mounting frame 2.

[0034] In this embodiment, after prolonged use, the display screen 1 will generate a large amount of heat, and some of this heat will accumulate between the mounting frame 2 and the display screen 1. At this time, the fan 20 installed on the mounting frame 2 can be turned on to extract the heat from inside the mounting frame 2 and exhaust it to the outside. Fresh air from the outside will enter inward through multiple air inlets 19 on the side wall of the mounting frame 2. The air will then be filtered by the filter plate 21, and dust and other impurities in the air will be intercepted by the filter plate 21 and pushed to the outside. The filtered air will then enter between the mounting frame 2 and the display screen 1 through the filter holes on the filter plate 21, achieving effective air circulation and ensuring heat exchange efficiency, thereby ensuring the normal use of the display screen 1. After prolonged use, the filter plate 21 can be removed for cleaning and replacement to ensure excellent filtration performance.

[0035] Please see Figures 2-6 As a further implementation of the overall device: a card block 22 is fixedly provided on one side of the mounting frame 2, and a card slot 23 is provided on the back side of the display screen 1, and the card slot 23 is adapted to the card block 22.

[0036] The back of the display screen 1 is provided with a plug rod 24, and the mounting frame 2 is fixedly provided with a sleeve 25 on one side, and the plug rod 24 is inserted into the sleeve 25.

[0037] A slide bar 26 is fixedly provided on the inner side of the lock sleeve 3, and a slide groove 27 is provided on the outer side of the lock rod 40, with the slide bar 26 sliding in the slide groove 27.

[0038] A tension spring 28 is movably installed in the movable groove 9, with its two ends connected to the inner wall of the movable groove 9 and the inner wall of the locking plate 7, respectively.

[0039] Both the end of the locking rod 16 and the inner edge of the locking groove 18 are designed with rounded corners.

[0040] A spring 29 is connected to one side of the locking sleeve 12, and the other end of the spring 29 is in contact with the release plate 11.

[0041] More specifically, when maintenance or replacement of internal components of mounting frame 2 is required, or when disassembly and maintenance of display screen 1 or fan 20 is required, first rotate release plate 11, causing release plate 11 to drive release groove 15 to rotate. When release groove 15 rotates to the position corresponding to horizontal plate 14, it pushes locking sleeve 12. Locking sleeve 12 drives horizontal plate 14 to slide through vertical plate 13, causing the corresponding horizontal plate 14 to gradually pass through release groove 15. At the same time, locking sleeve 12 and release plate 11 cooperate to compress spring 29. When spring 29 is compressed to its limit, a horizontal plate 14 near locking sleeve 12 just passes through release groove 15 and moves to the other side of release plate 11. Then continue to rotate release plate 11, causing release plate 11 to drive release groove 15 to rotate to a position where it is not aligned with horizontal plate 14. The horizontal plate 14 and the vertical plate 13 cooperate to limit the locking sleeve 12 to one side of the release plate 11. At this time, the locking sleeve 12 no longer limits the locking rod 16. Then, the control sleeve 4 is rotated in the forward direction, so that the control sleeve 4 drives the locking rod 16, which is slidably set on the side wall, to move. Then, the inner wall of the locking groove 18 presses against one end of the locking rod 16. Due to the rounded corner structure design at the end of the locking rod 16 and the edge of the inner wall of the locking groove 18, one end of the locking rod 16 will slide out of the locking groove 18, and the other end of the locking rod 16 will drive the connecting spring 17 to stretch. At the same time, the control sleeve 4 will drive the multiple control grooves 10 opened on the inner side to rotate in the forward direction. Since the control block 5 is slidably set in the control groove 10, and both the control block 5 and the control groove 10 adopt a variable diameter structure design, the control... Block 5 will drive the locking block 6 to move outward, so that the locking block 6 no longer limits one end of the locking plate 7. Then, the locking sleeve 3 will be pulled to one side, and the inner wall of the sloping top of the locking sleeve 3 will no longer limit one end of the outer side of the locking plate 7. Then, the tension spring 28 will gradually pull the locking plate 7 to rotate and reset, so that the locking plate 7 rotates and resets along the movable shaft 8 in the movable groove 9. Then, the other end of the locking plate 7 will rotate into the movable groove 9, so that multiple locking plates 7 are in a parallel state. Then, the locking sleeve 3 will be completely removed, and the mounting frame 2 and the display screen 1 will be separated, so that the insertion rod 24 is pulled out from the insertion sleeve 25 and the locking block 22 is removed from the locking groove 23. The fan 20 can be removed as needed, and the filter plate 21 can be removed for cleaning and replacement. Then, the corresponding parts The components are reassembled one by one, and then the display screen 1 is reassembled onto one side of the mounting frame 2, so that the locking block 22 is engaged in the slot 23, the insert rod 24 is inserted into the sleeve 25, and the locking rod 40 passes through the sleeve 25. Then, the locking sleeve 3 is re-fitted onto the outside of the locking rod 40, and the multiple sliding strips 26 on the inner side of the locking sleeve 3 slide into the sliding groove 27 on the outside of the locking rod 40. Then, one end of the locking plate 7 contacts the inner wall of the ramp at the top of the locking sleeve 3, and the ramp presses one end of the locking plate 7 inward, so that the locking plate 7 rotates along the movable groove 9 of the movable shaft 8, and the other end of the locking plate 7 drives the tension spring 28 to stretch. After the locking sleeve 3 is fully fitted onto the outside of the locking rod 40, the control sleeve 4 is rotated in the opposite direction, and the control sleeve 4 drives the locking rod 16 to rotate and reset.Simultaneously, the control sleeve 4 drives the inner control groove 10 to rotate in the opposite direction and reset. Then, the control block 5 drives the locking block 6 to slide and reset, so that the locking block 6 re-limits one end of the locking plate 7. When the locking block 6 is fully reset, the connecting spring 17 drives the locking rod 16 to slide and reset into the original locking groove 18. Then, the release plate 11 is rotated again, so that the release plate 11 drives the release groove 15 to rotate again. When the release groove 15 rotates to the position corresponding to the horizontal plate 14, the spring 29 pushes the locking sleeve 12 to slide and reset, and the locking sleeve 12 drives the horizontal plate 14 to slide and reset through the vertical plate 13. When the spring 29 is fully reset, the other two horizontal plates 14 are just... The release plates are moved to both sides of the release plate 11, and then the release plate 11 is rotated further, causing the release plate 11 to rotate the release groove 15 to a position that does not correspond to the horizontal plate 14 and the vertical plate 13. Then, the vertical plate 13 and the corresponding two horizontal plates 14 cooperate to limit the locking sleeve 12 to one side of the release plate 11. Combined with the preload applied to the locking sleeve 12 by the spring 29, the locking sleeve 12 will not easily slip, thus ensuring that the inner wall of the locking sleeve 12 stably limits the outer end of the locking rod 16. Then, the locking rod 16 and the locking groove 18 cooperate to stably lock the control sleeve 4, preventing the control sleeve 4 from rotating, thereby ensuring the stability of the installation structure and, consequently, the stability of the equipment operation.

[0042] In summary, during the use or operation of the entire device: after prolonged use, the display screen 1 will generate a large amount of heat, and some of this heat will accumulate between the mounting frame 2 and the display screen 1. At this time, the fan 20 installed on the mounting frame 2 can be turned on, and the fan 20 will draw out the heat inside the mounting frame 2 and exhaust it to the outside. At this time, fresh air from the outside will enter inward through the multiple air inlet slots 19 opened on the side wall of the mounting frame 2. The air will then be filtered by the filter plate 21, and the dust and other impurities contained in the air will be intercepted by the filter plate 21 and pushed to the outside. The filtered air will then enter between the mounting frame 2 and the display screen 1 through the filter holes opened on the filter plate 21, achieving effective air circulation and ensuring heat exchange efficiency, thereby ensuring the normal use of the display screen 1. After a long period of use, the filter plate 21 can be removed for cleaning and replacement to ensure excellent filtration performance.

[0043] When maintenance or replacement of internal components of mounting frame 2 is required, or when disassembly and maintenance of display screen 1 or fan 20 is needed, first rotate release plate 11, causing release plate 11 to drive release groove 15 to rotate. When release groove 15 rotates to the position corresponding to horizontal plate 14, it pushes locking sleeve 12. Locking sleeve 12 drives horizontal plate 14 to slide through vertical plate 13, causing the corresponding horizontal plate 14 to gradually pass through release groove 15. At the same time, locking sleeve 12 and release plate 11 cooperate to compress spring 29. When spring 29 is compressed to its limit, a horizontal plate 14 near locking sleeve 12 just passes through release groove 15 and moves to the other side of release plate 11. Then continue to rotate release plate 11, causing release plate 11 to drive release groove 15 to rotate to a position not corresponding to horizontal plate 14. Then, the horizontal plate 14 and the vertical plate 13 cooperate to limit the locking sleeve 12 to one side of the release plate 11. At this time, the locking sleeve 12 no longer limits the locking rod 16. Then, the control sleeve 4 is rotated in the forward direction, so that the control sleeve 4 drives the locking rod 16, which is slidably set on the side wall, to move. Then, the inner wall of the locking groove 18 presses against one end of the locking rod 16. Due to the rounded corner structure design at the end of the locking rod 16 and the edge of the inner wall of the locking groove 18, one end of the locking rod 16 will slide out of the locking groove 18, and the other end of the locking rod 16 will drive the connecting spring 17 to stretch. At the same time, the control sleeve 4 will drive the multiple control grooves 10 opened on the inner side to rotate in the forward direction. Since the control block 5 is slidably set in the control groove 10, and both the control block 5 and the control groove 10 adopt a variable diameter structure design, the control block 5 will... Move the locking block 6 outward so that it no longer limits one end of the locking plate 7. Then pull the locking sleeve 3 to one side. The inner wall of the sloping top of the locking sleeve 3 no longer limits one end of the locking plate 7. Then the tension spring 28 gradually pulls the locking plate 7 to rotate and reset, so that the locking plate 7 rotates and resets along the movable shaft 8 in the movable groove 9. Then the other end of the locking plate 7 will rotate into the movable groove 9, so that multiple locking plates 7 are in a parallel state. Then completely remove the locking sleeve 3. Then separate the mounting frame 2 and the display screen 1, so that the insertion rod 24 is pulled out from the insertion sleeve 25 and the locking block 22 is removed from the locking groove 23. The fan 20 can be removed as needed, and the filter plate 21 can be removed for cleaning and replacement. Then the corresponding parts are... After reassembly, the display screen 1 is reassembled onto one side of the mounting frame 2, so that the locking block 22 engages in the slot 23, the insert rod 24 is inserted into the sleeve 25, and the locking rod 40 passes through the sleeve 25. Then, the locking sleeve 3 is re-fitted onto the outside of the locking rod 40, and the multiple sliding strips 26 on the inner side of the locking sleeve 3 slide into the sliding groove 27 on the outer side of the locking rod 40. Then, one end of the locking plate 7 contacts the inner wall of the ramp at the top of the locking sleeve 3, and the ramp presses one end of the locking plate 7 inward, so that the locking plate 7 rotates along the movable groove 9 of the movable shaft 8, and the other end of the locking plate 7 drives the tension spring 28 to stretch. After the locking sleeve 3 is fully fitted onto the outside of the locking rod 40, the control sleeve 4 is rotated in the opposite direction, and the control sleeve 4 drives the locking rod 16 to rotate and reset.Simultaneously, the control sleeve 4 drives the inner control groove 10 to rotate in the opposite direction and reset. Then, the control block 5 drives the locking block 6 to slide and reset, so that the locking block 6 re-limits one end of the locking plate 7. When the locking block 6 is fully reset, the connecting spring 17 drives the locking rod 16 to slide and reset into the original locking groove 18. Then, the release plate 11 is rotated again, so that the release plate 11 drives the release groove 15 to rotate again. When the release groove 15 rotates to the position corresponding to the horizontal plate 14, the spring 29 pushes the locking sleeve 12 to slide and reset, and the locking sleeve 12 drives the horizontal plate 14 to slide and reset through the vertical plate 13. When the spring 29 is fully reset, the other two horizontal plates 14 are just... The release plates are moved to both sides of the release plate 11, and then the release plate 11 is rotated further, causing the release plate 11 to rotate the release groove 15 to a position that does not correspond to the horizontal plate 14 and the vertical plate 13. Then, the vertical plate 13 and the corresponding two horizontal plates 14 cooperate to limit the locking sleeve 12 to one side of the release plate 11. Combined with the preload applied to the locking sleeve 12 by the spring 29, the locking sleeve 12 will not easily slip, thus ensuring that the inner wall of the locking sleeve 12 stably limits the outer end of the locking rod 16. Then, the locking rod 16 and the locking groove 18 cooperate to stably lock the control sleeve 4, preventing the control sleeve 4 from rotating, thereby ensuring the stability of the installation structure and, consequently, the stability of the equipment operation.
