Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a waterproof structure for an outdoor junction box. Background Technology

[0002] Outdoor junction boxes are used for connecting outdoor electrical lines and need to withstand environmental erosion such as rain, snow, moisture, and dust. Waterproof performance is the key to ensuring their safe and stable operation. Existing structures often fail to provide waterproofing due to poor sealing, insufficient weather resistance, or complex installation. Therefore, it is urgent to optimize the waterproof structure design.

[0003] In existing technologies, the waterproof connectors in traditional outdoor junction boxes are prone to loosening due to vibration and aging, resulting in a decline in sealing performance over long-term use; and the maintenance of traditional outdoor junction boxes requires disassembly of the entire structure, which is complicated and leads to insufficient convenience in installation and maintenance.

[0004] Therefore, a waterproof structure for outdoor junction boxes is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof structure for outdoor junction boxes, which can solve the problems of reduced sealing performance after long-term use and the convenience of maintenance and installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof structure for an outdoor junction box, comprising a junction box body, wherein waterproof connectors are fixedly connected to the front, left, and right sides of the junction box body, a nested protective mechanism is movably connected to the outer side of the junction box body, and a sealing self-resetting component is movably connected to the outer side of the nested protective mechanism, wherein the nested protective mechanism includes a sealing bottom cover snapped into the bottom of the junction box body, a sealing top cover is provided on the top of the sealing bottom cover, a mounting plate is fixedly connected to the bottom of the sealing bottom cover, and a reinforcing component is movably connected to the top of the mounting plate, the reinforcing component being movably connected to the outer side of the waterproof connector.

[0007] Preferably, the sealing self-resetting assembly includes a supporting spindle fixedly connected to the rear side of the sealing bottom cover, the sealing top cover being rotatably connected to the outside of the supporting spindle, and an elastic sealing block being fixedly connected to the bottom of the sealing top cover.

[0008] Preferably, torsion springs are fixedly connected to both sides of the sealing top cover, and the torsion springs are fixedly connected to both sides of the inner side of the supporting main shaft.

[0009] Preferably, the top of the sealing bottom cover is provided with a sealing groove, and the elastic sealing block is inserted into the inner side of the sealing groove.

[0010] Preferably, the reinforcement component includes three sliding guide rails fixedly connected to the outside of the mounting plate frame, and the three sliding guide rails are respectively disposed at the bottom of the three waterproof joints. Fixing blocks are slidably connected to both sides of the top of the sliding guide rails, and two fixing blocks are respectively disposed on both sides of the waterproof joint.

[0011] Preferably, support blocks are fixedly connected to both sides of the top of the sliding guide rail, and a telescopic rod is fixedly connected to the side of the support block and the fixed block opposite to it. A compression spring is fixedly connected to the inner side of the telescopic rod, and a positioning magnetic block is fixedly connected to the side of the fixed block near the support block.

[0012] Preferably, a mounting ring is fixedly connected to the side of the sliding guide rail away from the sealing bottom cover, and fastening bolts are bolted to the inner side of the mounting ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application enhances waterproofing through a nested protective mechanism with double sealing protection. The telescopic rod with compression springs drives the fixing blocks to elastically clamp the waterproof connector from both sides, preventing the sealing performance from deteriorating over long-term use due to vibration and aging. At the same time, the top cover of the external sealing structure can rotate and the mounting plate can be moved outward, so that the entire structure does not need to be disassembled during maintenance, simplifying the operation. Thus, it not only solves the problem of easy deterioration of the sealing performance of traditional outdoor junction box waterproof connectors, but also improves the convenience of installation and maintenance. 2. This application, by setting a self-resetting sealing component, can enhance the sealing performance at the joint between the sealing top cover and the sealing bottom cover by squeezing and locking the elastic sealing block into the sealing groove. The torsion spring supporting the outside of the main shaft can quickly reset the top cover after it is opened and promote the locking of the elastic sealing block. The magnetic buckle maintains the sealing state. This solves the potential problems in the above examples, such as unreliable sealing between the sealing top cover and the sealing bottom cover, loose locking of the sealing block after reset, and difficulty in maintaining the sealing state, and further improves the reliability of the sealing structure.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: An outdoor waterproof junction box structure includes a junction box body 1. Waterproof connectors 2 are fixedly connected to the front, left and right sides of the junction box body 1. A nested protective mechanism 3 is movably connected to the outside of the junction box body 1. A sealing self-resetting component 4 is movably connected to the outside of the nested protective mechanism 3. The nested protective mechanism 3 includes a sealing bottom cover 31 that is snapped onto the bottom of the junction box body 1. A sealing top cover 32 is provided on the top of the sealing bottom cover 31. A mounting bracket 33 is fixedly connected to the bottom of the sealing bottom cover 31. A reinforcing component 34 is movably connected to the top of the mounting bracket 33. The reinforcing component 34 is movably connected to the outside of the waterproof connectors 2.

[0019] In this embodiment: When the outdoor junction box body 1 is used outdoors, in order to enhance waterproofing and prevent rainwater infiltration and short-term immersion, during installation, it is inserted into the inner side of the external sealing structure composed of the sealing bottom cover 31 and the sealing top cover 32 through the groove that fits the external shape. It achieves double protection in conjunction with its own sealing structure. The mounting plate bracket 33 on the rear side of the junction box body 1 is moved to the outside of the sealing bottom cover 31, which is convenient for fixing and installation by the mounting ring 5 and fastening bolt 6 on the outside of the mounting plate bracket 33. The sealing top cover 32 is rotatably connected to the top of the sealing bottom cover 31. It can be removed by flipping the cover or maintained inside during maintenance or adjustment. The wiring is connected and sealed by the waterproof connector 2. The reinforcement component 34 can fix the waterproof connector 2 in a straight position to prevent loosening due to long-term use and failure of the seal.

[0020] Specifically, such as Figure 2 , Figure 5As shown, the sealing self-resetting assembly 4 includes a support spindle 41 fixedly connected to the rear side of the sealing bottom cover 31, a sealing top cover 32 rotatably connected to the outside of the support spindle 41, and an elastic sealing block 42 fixedly connected to the bottom of the sealing top cover 32.

[0021] Specifically, such as Figure 2 , Figure 5 As shown, torsion springs 43 are fixedly connected to both sides of the sealing top cover 32, and the torsion springs 43 are fixedly connected to both sides of the inner side of the supporting main shaft 41.

[0022] Specifically, such as Figure 2 , Figure 5 As shown, a sealing groove 44 is provided on the top of the sealing bottom cover 31, and an elastic sealing block 42 is inserted into the inner side of the sealing groove 44.

[0023] In this embodiment: the elastic sealing block 42 is squeezed into the sealing groove 44 between the sealing top cover 32 and the sealing bottom cover 31 to seal the fitting area. There is a torsion spring 43 on the outer side of the supporting main shaft 41, which can quickly reset after opening and also promote the locking of the elastic sealing block 42. The magnetic buckle 7 keeps the sealing state.

[0024] Specifically, such as Figure 3 , Figure 4 As shown, the reinforcement component 34 includes three sliding guide rails 3401 fixedly connected to the outside of the mounting plate frame 33, and the three sliding guide rails 3401 are respectively set at the bottom of the three waterproof joints 2. The top two sides of the sliding guide rails 3401 are slidably connected with fixing blocks 3402, and the two fixing blocks 3402 are respectively set on both sides of the waterproof joint 2.

[0025] Specifically, such as Figure 3 , Figure 4 As shown, support blocks 3403 are fixedly connected to both sides of the top of the sliding guide rail 3401. A telescopic rod 3404 is fixedly connected to the opposite side of the support block 3403 and the fixing block 3402. A compression spring 3405 is fixedly connected to the inner side of the telescopic rod 3404. A positioning magnetic block 3406 is fixedly connected to the side of the fixing block 3402 near the support block 3403.

[0026] In this embodiment: A sliding guide rail 3401 is located on the side of the mounting plate 33 near the wiring terminal of the waterproof connector 2. Two sets of fixing blocks 3402 are slidably connected on the inner side. Before installation, the three sets of fixing blocks 3402 corresponding to the three waterproof connectors 2 are first pushed apart along the sliding guide rail 3401 to both sides, causing the telescopic rod 3404 and the internal compression spring 3405 between the fixing blocks 3402 and the support block 3403 of the support structure to retract. After being pushed a certain distance, the fixing blocks 3402 are attracted by the positioning magnet 3406. 02 and support block 3403 are used to keep telescopic rod 3404 and compression spring 3405 retracted. Then, the junction box body 1 is installed inside the sealed bottom cover 31 and sealed top cover 32. After connecting the waterproof connector 2 to complete the overall snap-fit ​​installation, the magnetic attraction limit of fixing block 3402 and support block 3403 is released one by one. The compression spring 3405 releases elastic potential energy to make telescopic rod 3404 extend rapidly, driving fixing block 3402 to elastically contact the wiring terminals of waterproof connector 2 from both sides, thereby straightening and fixing to prevent loosening.

[0027] Specifically, such as Figure 1 , Figure 2 As shown, a mounting ring 5 is fixedly connected to the side of the sliding guide rail 3401 away from the sealing bottom cover 31, and fastening bolts 6 are bolted to the inner side of the mounting ring 5.

[0028] Specifically, such as Figure 1 As shown, magnetic snap fasteners 7 are fixedly connected to the front sides of both the sealing bottom cover 31 and the sealing top cover 32.

[0029] In this embodiment: the mounting is fixed by the mounting ring 5 on the outside of the mounting plate frame 33 and the fastening bolt 6, and the sealing top cover 32 and sealing bottom cover 31 are kept sealed by the magnetic buckle 7.

[0030] Working principle: When using the outdoor junction box body 1, to further ensure its waterproof capability, prevent rainwater infiltration, and allow for short-term immersion, during installation, the outdoor junction box body 1 is first inserted into the inner side of the external sealing structure composed of the sealing bottom cover 31 and the sealing top cover 32 through the groove that fits its external shape. This, combined with the sealing structure of the junction box body 1 itself, achieves a double protection effect. The mounting plate bracket 33, originally used for installation on the rear side of the junction box body 1, is moved to the outside of the sealing bottom cover 31, facilitating fixed installation via the mounting ring 5 on the outside of the mounting plate bracket 33 and the fastening bolts 6. The top cover 32 is rotatably connected to the top of the sealed bottom cover 31. Therefore, when maintenance or adjustment of the junction box is required, it can be easily removed by flipping the cover or maintained inside. Waterproof connectors 2 are used at the wiring points of the junction box body 1 to achieve both wiring and sealing. To prevent the waterproof connectors 2 from loosening and causing sealing failure over time, a sliding guide rail 3401 is provided on the side of the mounting bracket 33 near the wiring end of the waterproof connector 2. Two sets of fixing blocks 3402 are slidably connected to the inner side of the sliding guide rail 3401. Before installation, the three sets of fixing blocks 3402 corresponding to the three waterproof connectors 2 are first pushed to both sides along the sliding guide rail 3401. The telescopic rod 3404 and its internal compression spring 3405 between the fixed locking block 3402 and the support block 3403 are retracted. After the fixed locking block 3402 is pushed a certain distance, the positioning magnetic block 3406 attracts the fixed locking block 3402 and the support block 3403, keeping the telescopic rod 3404 and the compression spring 3405 in a retracted state. Then, the junction box body 1 is installed inside the sealed bottom cover 31 and the sealed top cover 32, and the waterproof connector 2 is connected to complete the overall snap-fit ​​installation. Then, the magnetic attraction limit between the fixed locking block 3402 and the support block 3403 is contacted one by one, so that the telescopic rod 3404 extends rapidly under the release of the elastic potential energy of the compression spring 3405, thereby driving the fixed locking block 3404 to extend. Block 3402 achieves the effect of elastic contact between the terminals of the waterproof connector 2 on both sides, thereby aligning and fixing it to prevent loosening. In addition, during use, elastic sealing blocks 42 and sealing grooves 44 are provided between the sealing top cover 32 and the sealing bottom cover 31. The elastic sealing blocks 42 are squeezed into the sealing grooves 44 to seal and protect the contact area. A torsion spring 43 is provided along the outside of the main shaft 41 at the rotation point of the sealing top cover 32 and the sealing bottom cover 31. After opening, the torsion spring 43 quickly resets the structure and promotes the locking of the elastic sealing blocks 42. The magnetic buckle 7 maintains the sealing state. In summary, the waterproof structure of the outdoor junction box body 1 is optimized.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
