[0036] Please see Figure 1-6 A cable junction box includes a base 1. First limiting rods 3 are symmetrically fixedly connected to both sides of the top of the base 1. A box body 2 is slidably connected to the outside of the first limiting rods 3. Second limiting rods 4 are fixedly connected to both sides of the outside of the box body 2. Sealing plates 5 are slidably connected to the outside of the two second limiting rods 4. Multiple heat dissipation slots 6 are provided on both sides of the outside of the box body 2. A transmission component is provided inside the base 1.

[0037] Specifically, the transmission assembly includes a bidirectional lead screw 7 and a linkage unit. The bidirectional lead screw 7 is rotatably connected to the inside of the base 1. A motor 8 is fixedly connected to the outer side of the base 1 via a sealing cover. The output end of the motor 8 extends to the inner side of the base 1 and is fixedly connected to the bidirectional lead screw 7. Moving blocks 9 are connected to both outer sides of the bidirectional lead screw 7 via lead screw nut pairs. Connecting rods 10 are rotatably connected to the top of each of the two moving blocks 9. The tops of the two connecting rods 10 are rotatably connected to the housing 2. The sealing plate 5 can be moved via the linkage unit. The linkage unit includes a first transmission lead screw 11. The first transmission lead screw 11 is rotatably connected to both sides of the top of the base 1 extending into the inside of the housing 2. Rotating rods 20 are rotatably connected to both sides of the top of the inner wall of the housing 2. The rotating rods 20 are slidably connected to the first transmission lead screw 11. Inside the lead screw 11, threaded sleeves 12 are rotatably connected to both sides of the bottom of the inner wall of the housing 2. The threaded sleeves 12 are connected to the outside of the first transmission lead screw 11 through the lead screw nut pair. The outside of the two rotating rods 20 are fixedly connected to the first bevel gears 13. The outside of the housing 2 are rotatably connected to the worm gears 14. One end of each of the two worm gears 14 extends into the inside of the housing 2 and is fixedly connected to the second bevel gears 15. The first bevel gears 13 and the second bevel gears 15 are meshed. The outside of the housing 2 are rotatably connected to the second transmission lead screws 16 through the limit blocks. The outside of each of the two second transmission lead screws 16 is fixedly connected to the worm gears 17. The worm gears 17 are meshed with the corresponding worm gears 14. The two sealing plates 5 are respectively connected to the outside of the corresponding second transmission lead screws 16 through the lead screw nut pair.

[0038] Through the above technical solution, the heat dissipation grooves 6 on both sides can dissipate heat from the device. During the rainy season, the motor 8 is started, and the output end of the motor 8 drives the bidirectional lead screw 7 to rotate. The bidirectional lead screw 7 then drives the two moving blocks 9 to move to both sides through the lead screw nut pair. This causes the moving blocks 9 to drive the corresponding connecting rod 10 to push the box 2 upward under the limit of the first limit rod 3, which can drive the box 2 to rise to a certain height, avoiding water accumulation that could cause soaking or water entering the interior of the box 2. In daily use, the box 2 can be lowered to the bottom to improve stability. During the upward movement of the box 2, the threaded sleeve 12 can rise synchronously, and at the same time, the rotating rod 20 can slide upward inside the first transmission lead screw 11. The threaded sleeve 12 then drives the corresponding first transmission lead screw 11 to rotate through the lead screw nut pair. The first transmission lead screw 11 then drives the rotating rod 20 and the first bevel gear 13 to rotate, so that the first bevel gear 13 rotates. Gear 13 drives the second bevel gear 15 and worm 14 to rotate through meshing. Worm 14 drives the corresponding worm wheel 17 and second transmission screw 16 to rotate through meshing. The second transmission screw 16 then drives the corresponding sealing plate 5 to move towards the heat dissipation groove 6 under the limit of the second limit rod 4 through the screw nut pair, until the heat dissipation groove 6 is sealed. This effectively prevents rainwater and water vapor from entering, effectively improving the waterproof performance of the device. In addition, the inclined surface of the inclined plate 19 allows rainwater to slide off quickly, preventing it from accumulating on the top of the box 2. During the rainy season, the device can lift the box 2 upward to prevent water accumulation from soaking or entering the interior of the box 2. During daily use, the box 2 can be lowered to the bottom to improve stability. After the box 2 is raised, it can drive the sealing plates 5 on both sides to block and seal the heat dissipation groove 6, effectively preventing rainwater and water vapor from entering, further improving the waterproof performance of the device.

[0039] Specifically, the threads of the two first transmission screws 11 are opposite, a door 18 is installed on the outside of the housing 2, a handle is fixedly connected to one side of the outside of the door 18, universal wheels are symmetrically installed on both sides of the bottom of the base 1, an inclined plate 19 is fixedly connected to the top of the housing 2, multiple heat dissipation slots 6 are all set obliquely to the outside and downward of the housing 2, sealing gaskets are set on the inner side of the two sealing plates 5, and the motor 8 is electrically connected to the external controller.

[0040] Through the above technical solution, the set door 18 allows staff to easily open and maintain the internal components, and the set casters allow the device to be easily pushed to any working position.

[0041] During use, the device can be cooled by the heat dissipation slots 6 on both sides. In rainy weather, the motor 8 is started, and the output of the motor 8 drives the bidirectional lead screw 7 to rotate. The bidirectional lead screw 7 then drives the two moving blocks 9 to move to both sides through the lead screw nut pair. This causes the moving blocks 9 to drive the corresponding connecting rod 10 to push the box 2 upward under the limit of the first limit rod 3, which can raise the box 2 to a certain height to prevent water accumulation and soaking or water entering the interior of the box 2. In daily use, the box 2 is lowered to the bottom to improve stability. During the upward movement of the box 2, the threaded sleeve 12 rises synchronously, and the rotating rod 20 slides upward inside the first transmission lead screw 11. The threaded sleeve 12 then drives the corresponding first transmission lead screw 11 to rotate through the lead screw nut pair. The first transmission lead screw 11 then drives the rotating rod 20 and the first bevel gear 13 to rotate, so that the first bevel gear 13 drives the second bevel gear 15 and the worm gear 14 to rotate through the meshing relationship. 14 drives the corresponding worm gear 17 and the second transmission screw 16 to rotate through the meshing relationship. The second transmission screw 16 then drives the corresponding sealing plate 5 to move towards the heat dissipation groove 6 under the limit of the second limit rod 4 through the screw nut pair, until the heat dissipation groove 6 is sealed. This can effectively prevent rainwater and water vapor from entering, effectively improving the waterproof performance of this device. In addition, the inclined surface of the inclined plate 19 can allow rainwater to slide off quickly, preventing it from accumulating on the top of the box 2. This device can lift the box 2 upward during the rainy season to prevent water accumulation from soaking or entering the interior of the box 2. In daily use, the box 2 can be lowered to the bottom to improve the stability of use. After the box 2 is raised, it can drive the sealing plates 5 on both sides to block and seal the heat dissipation groove 6, which can effectively prevent rainwater and water vapor from entering, further improving the waterproof performance of this device. The box door 18 can be opened by the staff for maintenance of the internal components. The universal wheels can be used to push this device to any working position.
