DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Example

[0019] like Figure 1-4 As shown, the utility model proposes a split type external wiring junction box, including a box body 1 and a sealing cover 2, the upper end opening of the box body 1 is clamped with the sealing cover 2, the outer periphery of the upper end opening of the box body 1 is provided with a sealing groove 16, a sealing strip 22 is fixed to the bottom of the sealing cover 2 and at a position corresponding to the sealing groove 16, a pair of fixing columns 23 are fixed to the bottom of the sealing cover 2, a sealing plate 3 is fixed to the bottom of the fixing columns 23, a sealing airbag 31 is fixed to the outer side wall of the sealing plate 3, an inflation frame 4 is fixed between the sealing plate 3 and the sealing cover 2, and an inflation component for inflating the sealing airbag 31 is arranged in the inflation frame 4.

[0020] The inflation component includes an inflation groove 41 and a piston plate 43. The inflation groove 41 is provided in the inflation frame 4. A connecting hole 42 is provided between the bottom of the inflation groove 41 and the sealing airbag 31. The piston plate 43 is slidably connected in the inflation frame 4. A threaded rod 45 is fixed at the center position of the upper end of the piston plate 43. A threaded sleeve 46 is rotatably connected at the center position of the sealing cover 2. The upper end of the threaded rod 45 is threadedly connected in the threaded sleeve 46. A rotating plate 47 is fixed at the upper end of the threaded sleeve 46. The rotating plate 47 is rotatably connected to the top of the sealing cover 2. A limiting rod 44 is fixed in the inflation groove 41. The limiting rod 44 passes through the piston plate 43 and is slidably connected to the piston plate 43. Rotating the rotating plate 47 can drive the threaded sleeve 46 to rotate, so that the threaded rod 45 moves downward, pushing the piston plate 43 to move downward, and the gas in the inflation groove 41 is injected into the sealing airbag 31 through the connecting hole 42, so that the sealing airbag 31 expands.

[0021] The box body 1 is composed of a main box 11 and an additional box 12. Mounting plates 13 are fixed on both sides of the bottom of the additional box 12. Mounting holes 15 are provided on the mounting plates 13. Positioning holes 14 are provided at the four corners of the upper ends of the main box 11 and the additional box 12. Fixing bolts 21 that match the positioning holes 14 are installed at the four corners of the sealing cover 2.

In this process, the sealing strip 22 is inserted into the sealing groove 16 to seal the connection between the sealing cover 2 and the box body 1, thereby reducing the risk of water stains entering. At the same time, when the sealing cover 2 is installed, the sealing plate 3 will be inserted into the box body 1 simultaneously. When the sealing cover 2 is fixed, the rotating plate 47 is rotated to drive the threaded sleeve 46 to rotate, so that the threaded rod 45 moves downward, pushing the piston plate 43 to move downward, and the gas in the inflation groove 41 is injected into the sealing airbag 31 through the connecting hole 42, so that the sealing airbag 31 expands, and then the outer wall of the sealing airbag 31 will be tightly attached to the inner wall of the box body 1, further increasing the sealing inside the box body 1, ensuring that water stains cannot penetrate, and improving the waterproof effect of the junction box.
