A fixing ring is fixedly connected to the outer wall of the top of the waterproof cover, and the fixing ring is located above the connection port. The interior of the waterproof box has two wiring slots, and a pressure plate is movably connected inside each of the two wiring slots. A threaded rod is movably connected to the top of the waterproof box, and the bottom end of the threaded rod is rotatably connected to the pressure plate. A rack is fixedly connected to one side of the pressure plate. A slide is provided inside the waterproof box, and the rack moves along the slide. A gear is movably connected to the middle position of the slide, and the rack meshes with the gear. A detachable fixing component is provided between the top end of the threaded rod and the fixing ring. A sealing ring with a central hole is fixedly connected to the opening of the wiring slot.

[0007] As a further embodiment of this utility model, the connecting component includes two fixing blocks, which are respectively fixed to the outer walls of the waterproof box on both sides by bolts. Connecting blocks are fixedly connected to the outer walls of both sides of the waterproof cover. Screws are movably inserted into the interior of the connecting blocks, and the screws are threadedly connected to the fixing blocks.

[0022] Reference Figures 1-3 A waterproof orthopedic external frame junction box includes a waterproof box 5. A waterproof cover 9 is mounted on the top of the waterproof box 5 via a detachable connecting assembly. A connection port is provided on the top of the waterproof cover 9. A fixing ring 3 is bolted to the outer wall of the top of the waterproof cover 9, and the fixing ring 3 is located above the connection port. Two wiring slots 15 are provided inside the waterproof box 5. Wires located on both sides of the waterproof box 5 are passed through the wiring slots 15, and the two corresponding wires are connected. Pressure plates 11 are slidably connected inside both wiring slots 15. A threaded rod 19 is threaded to the top of the waterproof box 5, and the bottom end of the threaded rod 19 is rotatably connected to the pressure plate 11. A rack 13 is bolted to one side of the pressure plate 11. A slide rail 1 is provided inside the waterproof box 5. 4. The rack 13 moves along the slide 14. The middle position of the slide 14 is rotatably connected to the gear 12, and the rack 13 meshes with the gear 12. A detachable fixing component is provided between the top of the threaded rod 19 and the fixing ring 3. Rotating the threaded rod 19 causes the pressure plate 11 connected to it to drive the rack 13 to move downward, thereby causing the gear 12 to rotate. This causes the rack 13 at the bottom to drive the pressure plate 11 connected to it to move upward, thereby pressing and positioning the wire connection in the wiring groove 15. At the same time, the height of the pressure plate 11 is fixed by the fixing component. A sealing ring 4 with a round hole in the middle is glued to the opening of the wiring groove 15. Through the cooperation of the sealing ring 4, the waterproof cover 9 and the waterproof box 5, the outside of the device can be waterproofed.

[0023] In this utility model, it should be noted that the connecting assembly includes two fixing blocks 6, which are respectively fixed to the outer walls of the waterproof box 5 on both sides by bolts. Connecting blocks 7 are fixed to the outer walls of the waterproof cover 9 on both sides by bolts. Screws 8 are movably inserted into the interior of the connecting blocks 7, and the screws 8 are threadedly connected to the fixing blocks 6. Rotating the screws 8 separates them from the fixing blocks 6, and the operator moves the waterproof cover 9 upwards to separate it from the waterproof box 5, thus achieving disassembly. The fixing assembly includes two insertion holes 2, which are opened on the inner walls of the fixing ring 3 on both sides. A sliding groove 18 is opened at the top of the threaded rod 19, and a connecting rod is provided in the sliding groove 18. Moving posts 17 are slidably connected to both ends of the connecting rod, and the moving posts 17 can be inserted into the insertion holes 2. A spring 16 is sleeved in the middle of the connecting rod, and both ends of the spring 16 are respectively connected to the moving posts 17. The movable column 17 is slidably connected to the slide groove 18. The threaded rod 19 drives the pressure plate 11 to move downward and press the connection of the wire. At the same time, the threaded rod 19 moves downward first, causing the movable column 17 to move downward and contact the fixed ring 3, so that the curved end of the movable column 17 is squeezed. At this time, the movable column 17 moves towards the middle along the connecting rod, and the spring 16 contracts until the movable column 17 moves downward and corresponds to the position of the insertion hole 2. At this time, the spring 16 rebounds and extends, so that the movable column 17 is inserted into the insertion hole 2. Then, the height of the pressure plate 11 is fixed by the threaded rod 19. A connecting ring 10 is fixed to one side of the outer wall of the waterproof cover 9 by bolts, which facilitates the connection of the device with external devices. The top of the threaded rod 19 passes through the fixed ring 3 and is welded with a knob 1, which makes it convenient for the operator to rotate the threaded rod 19. One end of the movable column 17 is provided with a curved surface.

[0024] Working principle: In use, first, the wires on both sides are inserted into the wiring groove 15 through the holes inside the sealing ring 4, and the two corresponding wires are connected. Then, the threaded rod 19 is rotated, causing the pressure plate 11 connected to it to drive the rack 13 to move downward, thereby causing the gear 12 to rotate. This causes the rack 13 at the bottom to drive the pressure plate 11 connected to it to move upward, thereby pressing and positioning the wire connection in the wiring groove 15. At the same time, the threaded rod 19 moves downward, first causing the moving column 17 to move downward and contact the fixing ring 3, so that the arc-shaped end of the moving column 17 is squeezed. At this time, the moving column 17 moves towards the middle along the connecting rod, and the spring 16 contracts until the moving column 17 moves downward and corresponds to the position of the insertion hole 2. At this time, the spring 16 rebounds and extends, thereby inserting the moving column 17 into the insertion hole 2, and the height of the pressure plate 11 is fixed by the threaded rod 19.
