Description

Technical Field

[0001] This utility model relates to the field of outdoor LED cabinets, and more particularly to outdoor front-opening LED cabinets. Background Technology

[0002] Outdoor LED display cabinets are widely used in advertising media, sports stadiums, traffic guidance, and urban lighting. They need to be exposed to harsh environments such as sunlight, rain, wind, sand, and alternating high and low temperatures for a long time. Therefore, extremely high requirements are placed on structural strength, waterproof and dustproof performance, heat dissipation capacity, and ease of maintenance. At present, most mainstream outdoor LED cabinets adopt a rear-maintenance design, that is, module replacement or circuit maintenance is carried out by opening the back of the cabinet. However, in high-altitude installations (such as building curtain walls and column screens) or space-constrained scenarios (such as embedded walls and narrow passages), the rear maintenance method has problems such as difficult operation, the need for large hoisting equipment, high maintenance costs, or even impracticality. To solve the above pain points, the industry has gradually introduced front-maintenance LED cabinets, which allow for quick disassembly and assembly from one side of the display surface.

[0003] However, existing front-opening LED cabinets still have significant technical defects: First, most products lack effective buffer mechanisms, and the lid is prone to sudden flipping due to its own weight or wind load during opening, which not only poses a risk of injury but also easily leads to hinge deformation or loosening of internal components; when closing, it often violently impacts the cabinet due to the lack of damping control, causing the sealing strip to be crushed, the seams to be misaligned, or even the LED modules to be damaged. Second, existing lids mostly rely on simple buckles or single-point locking, which cannot achieve stable positioning at multiple angles. During maintenance, the lid needs to be continuously supported by personnel, which seriously affects operational efficiency and safety.

[0004] Therefore, it is necessary to provide a new outdoor front-opening LED enclosure to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an outdoor front-opening LED cabinet.

[0006] The outdoor front-opening LED cabinet provided by this utility model includes a cabinet, a connecting plate two fixedly connected to the top of the cabinet, a rotating ring two fixedly connected to one side of the connecting plate two, a rotating shaft one fixedly connected to the inner wall of the rotating ring two, a rotating shaft two fixedly connected to the inner wall of the rotating shaft one, a spring sleeved on the outer wall of the rotating shaft two, one end of the spring fixedly connected to one end of the rotating shaft one, and a mounting ring fixedly connected to the other end of the spring. The inner wall of the mounting ring is slidably connected to the outer wall of the rotating shaft two, a spline fixedly connected to one end of the mounting ring, and a handle fixedly connected to one end of the mounting ring. The rotating ring one is rotatably connected to the outer wall of the rotating shaft one, and a groove is formed on the inner wall of the rotating ring one. A connecting plate one is fixedly connected to the bottom of the rotating ring one, and a cabinet cover is fixedly connected to the bottom of the connecting plate one.

[0007] Preferably, the outer wall of the second rotating shaft is fixedly connected with a key, and the inner wall of the mounting ring is provided with a groove.

[0012] Compared with related technologies, the outdoor front-opening LED cabinet provided by this utility model has the following beneficial effects: by pulling the handle, the user slides the spline out of the inner wall of the slot, releasing the locking restriction on the rotating ring one, allowing the user to lift the cabinet cover and open the cabinet.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 ,in, Figure 1 A schematic diagram of a preferred embodiment of the outdoor front-opening LED cabinet provided by this utility model; Figure 2 for Figure 1 The diagram shown is a schematic of the unfolded box lid. Figure 3 for Figure 1 The diagram shows the structural schematic of the support component. Figure 4 for Figure 1 The diagram shows the structure of the locking assembly. Figure 5 for Figure 1 The diagram shows the disassembled structure of the locking assembly.

[0016] In the specific implementation process, such as Figure 1-3 As shown, this utility model provides an outdoor front-opening LED cabinet including a cabinet 1. Heat dissipation plates 3 are fixedly connected to both sides of the cabinet 1. Multiple heat dissipation plates 3 are arranged in an equidistant array on both sides of the cabinet 1. A fixing plate 21 is fixedly connected to the inner side of the cabinet cover 2. Multiple mounting holes are equidistantly opened on the fixing plate 21. A rotating rod 7 is rotatably connected to the inner wall of the mounting holes. A hydraulic damper 4 is fixedly connected to one end of the rotating rod 7. A rotating rod 6 is fixedly connected to one end of the hydraulic damper 4. A mounting plate 5 is rotatably connected to the outer wall of the rotating rod 6. The bottom of the mounting plate 5 is fixedly connected to the bottom of the inner wall of the cabinet 1. The two fixing plates 21, the rotating rod 7, the hydraulic damper 4, the rotating rod 6, and the mounting plate 5 are symmetrically arranged at both ends of the cabinet cover 2. It should be noted that the hydraulic damper 4 is a tension damper. When the cover 2 is lifted upwards, the angle between the first rotating rod 6 and the second rotating rod 7 increases, and the hydraulic damper 4 is stretched, generating a damping force to slow down the opening speed of the cover 2. When closed, the hydraulic damper 4 slowly retracts to prevent the cover 2 from falling rapidly. The first rotating rod 6 is hinged to the mounting plate 5 through a pin to form a fixed fulcrum. The second rotating rod 7 is hinged to the mounting hole of the fixed plate 21 through a pin and rotates synchronously with the cover 2. The two ends of the hydraulic damper 4 are respectively hinged to the two rotating rods to form a four-bar linkage buffer mechanism.

[0017] In the specific implementation process, refer to Figure 4-5 As shown, this utility model provides an outdoor front-opening LED cabinet. A connecting plate 21 is fixedly connected to the top of the cabinet 1. A rotating ring 20 is fixedly connected to one side of the connecting plate 21. A rotating shaft 12 is fixedly connected to the inner wall of the rotating ring 20. A rotating shaft 23 is fixedly connected to the inner wall of the rotating shaft 12. A spring 14 is sleeved on the outer wall of the rotating shaft 23. One end of the spring 14 is fixedly connected to one end of the rotating shaft 12, and the other end of the spring 14 is fixedly connected to a mounting ring 17. The inner wall of the mounting ring 17 is slidably connected to the outer wall of the rotating shaft 23. One end of the mounting ring 17 is fixedly connected to... A handle 19 is fixedly connected to one end of a spline 16 and a mounting ring 17. A rotating ring 9 is rotatably connected to the outer wall of a rotating shaft 12. A groove 10 is opened on the inner wall of the rotating ring 9. A connecting plate 8 is fixedly connected to the bottom of the rotating ring 12. A cover 2 is fixedly connected to the bottom of the connecting plate 8. A locking key 15 is fixedly connected to the outer wall of a rotating shaft 2 13. A slot 18 is opened on the inner wall of the mounting ring 17. Two springs 14, a mounting ring 17, a spline 16, a handle 19, a locking key 15, and a slot 18 are symmetrically arranged at both ends of a rotating shaft 12. Grooves 10 are opened at both ends of a rotating ring 9. It should be noted that the groove 10 has multiple grooves along the circumference. The spline 16 can be inserted into any groove under the preload of the spring 14, realizing the mechanical self-locking of the cover 2 in the closed state and at multiple maintenance angles. When the angle needs to be changed, pull the handle 19 to disengage the spline 16 from the groove 10, and the cover 2 can be rotated freely. The locking key 15 and the locking groove 18 form an axial limiting structure to ensure that the spline 16 is always aligned with the groove 10. At the same time, the mounting ring 17 is allowed to move a short distance axially with the operation of the handle 19 to disengage the spline 16 from the groove 10. The rotating ring 19 and the rotating ring 20 are coaxially mounted on the outer wall of the rotating shaft 12. They can rotate relative to each other and together form an integrated hinge mechanism between the cover 2 and the box body 1. The mechanism (connecting plate 18, rotating ring 19, groove 10, connecting plate 21, rotating shaft 12) 2. Two sets of components (rotating shaft 13, spring 14, locking key 15, spline 16, mounting ring 17, locking groove 18, handle 19, and rotating ring 20) are symmetrically arranged on the left and right sides of the top of the housing 1 to ensure balanced force on the cover 2. Spring 14 is a helical compression spring, which is in a pre-compressed state under natural conditions. When the user pulls the handle 19, the mounting ring 17 overcomes the axial thrust of the spring 14 and slides outward, causing the spline 16 to disengage from the groove 10. After releasing the handle 19, the restoring thrust of the spring 14 pulls the mounting ring 17 back to its original position, causing the spline 16 to re-embed into the groove 10, achieving automatic locking. An annular dustproof sealing ring (such as a fluororubber O-ring) is provided at the fit gap between rotating ring 19 and rotating ring 20 to prevent rainwater and dust from entering the internal transmission mechanism. Drainage micro-holes are provided at the end of rotating shaft 12 to prevent water accumulation.

[0018] The working principle provided by this utility model is as follows: The user holds the handle 19 on either side of the top of the box cover 2 and pulls it out horizontally along the axial direction. The mounting ring 17 overcomes the pre-compression thrust of the spring 14 and slides along the axis of the rotating shaft 13. The spline 16 disengages from the groove of the current slot 10, releasing the lock on the rotating ring 9. The user continues to lift the box cover 2. The box cover 2 rotates around the top integrated hinge by the rotating ring 9 and the rotating ring 20. At the same time, the fixing plate 21 on the inner side of the box cover 2 drives the rotating rod 7 to rotate synchronously. The angle between the rotating rod 7 and the rotating rod 6 on the bottom mounting plate 5 increases, stretching the hydraulic damper 4. The hydraulic damper 4 generates a reverse damping force, which effectively slows down the opening speed of the box cover 2 and prevents it from suddenly flipping over due to gravity or wind. When the cover 2 is opened to the required maintenance angle, release the handle 19, the spring 14 returns to the pre-compression state, pushes the mounting ring 17 to return to its axial position, and the spline 16 automatically embeds into the groove of the flower groove 10 at the corresponding angle to achieve mechanical self-locking. The cover 2 is stably maintained at this angle without manual support, making it easy to operate the internal LED module or circuit with both hands. After maintenance, pull handle 19 again to disengage spline 16 from the groove, and slowly lower the cover 2. The hydraulic damper 4 controls the retraction speed to prevent the cover 2 from falling rapidly and hitting the housing 1. When the cover 2 is fully closed, release handle 19. Spring 14 pushes spline 16 to accurately embed into the groove 10, achieving automatic locking and repositioning. Throughout the use, the equidistant array heat dissipation plates 3 on both sides of the housing 1 continuously dissipate heat from internal components such as LED driver power supply, reducing the operating temperature and extending the equipment life through natural convection.

[0019] This outdoor front-opening LED cabinet has the following advantages: 1. The hydraulic damper 4, as a tension-type buffer element, is stretched when the cover 2 is opened to generate damping force, effectively suppressing sudden overturning caused by gravity or wind load. When closed, the hydraulic damper 4 slowly retracts to prevent the cover 2 from falling rapidly and hitting the box body 1, avoiding damage to LED modules, sealing strips or structural components. It is suitable for high-altitude, strong wind or narrow space operations, reducing the operational risks for maintenance personnel. 2. The spline 16 and the groove 10 work together to form a multi-position mechanical self-locking mechanism. After reaching the target angle, the handle 19 is released and the spring 14 automatically pushes the spline 16 to reset and embed into the corresponding groove. There is no need for manual support of the cover 2. Maintenance personnel can freely operate the internal equipment with both hands, improving maintenance efficiency and comfort. 3. Two sets of hydraulic buffer mechanisms and self-locking hinges are symmetrically arranged on the left and right sides to ensure that the load is evenly distributed during the opening or closing of the cover 2, avoiding torsional deformation, sealing failure or hinge fatigue fracture caused by unilateral force.
