Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically a waterproof and dustproof outdoor distribution box. Background Technology

[0002] Distribution boxes are electrical equipment characterized by their small size, easy installation, unique technical performance, fixed location, unique configuration functions, lack of site restrictions, widespread application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. The numerous parameters listed on distribution box data generally indicate that low-voltage distribution boxes are constructed according to electrical wiring requirements, assembling switching equipment, measuring instruments, protective electrical devices, and auxiliary equipment within enclosed or semi-enclosed metal cabinets or panels.

[0003] For example, Chinese patent CN219419918U, entitled "A Waterproof and Dustproof Outdoor Distribution Box," includes a box body with heat dissipation vents on both the left and right sides, each containing a dustproof mesh. Protective covers are connected to both sides of the box body, and a rain shield is attached to the top. An opening on the front of the box body houses a rotating door. A partition is installed inside the box, with a fixed plate connected to the top of the partition. The side wall of the fixed plate has a movable component corresponding to the protective cover. This invention utilizes a rotating lead screw, which moves a movable block via a threaded mechanism. As the movable block moves, it pulls a connecting rod, which in turn pulls a slider. This slider slides within the slotted opening and pulls the connecting plate, which in turn pulls the protective cover, moving it to the side of the dustproof mesh and exposing it. This increases the heat dissipation area of ​​the box body, effectively improving its cooling performance.

[0004] While the waterproof and dustproof outdoor distribution box described in the aforementioned patent is practical and convenient, it also has shortcomings. Due to the unpredictable outdoor weather, during emergency repairs, rainwater can easily seep into the distribution box after the door is opened, potentially wetting the electrical components inside. When these components are wet, they are prone to short circuits and leakage. Short circuits can generate large currents, potentially burning out electrical components or causing a fire, while leakage can lead to electric shock, posing a threat to personal safety.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-5 The present invention provides a technical solution: the waterproof and dustproof outdoor distribution box includes a box body 1, a rain shield 6, a locking assembly, and a transmission assembly. Two boxes 2 are symmetrically rotatably connected to one side of the box body 1. The rain shield 6 is horizontally slidably connected to the top of the box body 1. When the two boxes 2 are opened relative to the box body 1, the transmission assembly drives the rain shield 6 to slide horizontally out of the box body 1. When the two boxes 2 are opened to the maximum angle relative to the box body 1, the locking assembly can fix and lock the rain shield 6. Specifically, the bottom of the box body 1 is provided with heat dissipation holes 17 for heat dissipation.

[0022] In this embodiment, the transmission assembly includes two hinge rods 8. One end of each hinge rod 8 is hinged to one side of each of the two doors 2 facing the inside of the housing 1. Two cylinders 10 are symmetrically arranged at the bottom of the rain shield 6. The other ends of the two hinge rods 8 are rotatably sleeved with the two cylinders 10. Specifically, a guide groove is horizontally opened inside the housing 1, and the rain shield 6 is horizontally slidably connected within the guide groove. Two sliding grooves 9 are symmetrically opened inside the housing 1, and the two cylinders 10 are horizontally slidably connected within the two sliding grooves 9 respectively. The height of the rain shield 6 is higher than... At the top of the two boxes 2, and when the boxes 2 are opened relative to the box body 1, since the two cylinders 10 can only move horizontally in a straight line along the length of the slide groove 9, the other end of the hinge rod 8 drives the two cylinders 10 to move horizontally in a straight line. The two cylinders 10 drive the rain shield 6, which is set on the top together, to slide horizontally outward toward the box door 2. This can effectively prevent rainwater from splashing onto the electrical components such as circuit breakers, contactors, and terminals inside the box body 1, avoiding problems such as short circuits, corrosion, and insulation degradation, extending the equipment life and reducing the failure rate.

[0023] In this embodiment, a cover plate 3 is provided on the top of the box 1. The cover plate 3 is triangular in shape, and two water collection troughs 4 are symmetrically opened on both sides of the cover plate 3. A drain outlet 5 is provided on one side of each of the two water collection troughs 4. Specifically, the triangular shape allows rainwater to flow down along the inclined angle of the cover plate 3, preventing rainwater from accumulating on the top of the cover plate 3. The water collection troughs 4 are used to collect rainwater from the top, and the rainwater can be discharged from the drain outlet 5 along the water collection troughs 4, ensuring the dryness inside the box 1.

[0024] In this embodiment, the locking assembly includes a plug rod 12, which is vertically slidably connected to the cover plate 3 via an elastic unit. A slot 16 is provided on the top of the rain shield 6, and the plug rod 12 is inserted into the slot 16. The top of the plug rod 12 is inclined. A bolt 7 is screwed onto the top of the cover plate 3. The end of the bolt 7 facing the plug rod 12 abuts against the top of the plug rod 12. Specifically, in windy weather, the operator can use their body or one hand to control the door 2 at its maximum angle. At this time, the slot 16 on the rain shield 6 is located below the plug rod 12. By rotating the bolt 7, the bolt 7 continuously advances towards the plug rod 12, pushing the plug rod 12 downward so that the plug rod 12 is inserted into the slot 16, thus preventing the door 2 from shaking too much and affecting the maintenance process.

[0025] In another embodiment, the size of the slot 16 can be increased along the length of the slide 9 to increase the fault tolerance of the insertion rod 12 and the slot 16, and reduce the requirement for the accuracy of the insertion timing.

[0026] In this embodiment, the elastic unit includes a spring 14, a groove 15 is vertically formed in the cover plate 3, a retaining ring 13 is sleeved on the insert rod 12, the retaining ring 13 is vertically slidably connected in the groove 15, and the spring 14 is disposed between the retaining ring 13 and the bottom wall of the groove 15. Specifically, a vertical groove 11 is vertically formed in the cover plate 3 and communicates with the groove 15 and the guide groove. The insert rod 12 is vertically slidably connected in the vertical groove 11. During the process of unscrewing the bolt 7, the retaining ring 13 is driven by the action of the spring 14 to move the insert rod 12 vertically upward to reset.

[0027] Working principle: When inspecting or maintaining the internal components of this waterproof and dustproof outdoor distribution box 1, the opening of the door 2 is utilized. As the door 2 opens relative to the box 1, the two cylinders 10 can only move horizontally along the length of the slide groove 9. The other end of the hinge rod 8 then drives the two cylinders 10 to move horizontally, causing the rain shield 6, which is jointly mounted on top, to slide horizontally outwards towards the door 2. This effectively prevents rainwater from splashing onto the circuit breakers, contactors, terminals, and other electrical components inside the box 1. In terms of air components, problems such as short circuits, corrosion, and insulation degradation are avoided, extending equipment life and reducing failure rate. In windy weather, the operator can use their body or one hand to control the door 2 at its maximum angle. At this time, the slot 16 on the rain shield 6 is located below the plug rod 12. By rotating the bolt 7, the bolt 7 will continuously advance towards the plug rod 12, pushing the plug rod 12 down so that the plug rod 12 is inserted into the slot 16, preventing the door 2 from shaking too much and affecting the maintenance process.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
