[0013] Example 1, by Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6This utility model relates to a high-sealing aviation plug-specific junction box, comprising a box body 1, a junction board assembly 2 fixedly installed at the bottom of the box body 1, five through holes 3 extending through the outer side of the box body 1, two of which are symmetrically arranged on one side of the box body 1 and the other three are evenly arranged on the other side of the box body 1, a wiring sealing assembly 4 fixedly installed inside each of the five through holes 3, a cover plate 5 installed on the top of the box body 1, a sealing strip 6 fixedly installed at the bottom of the cover plate 5, connecting bolts 7 installed at the four corners of the cover plate 5, and connecting seats 8 symmetrically fixedly installed at the top of the front and rear sides of the box body 1, with the connecting bolts 7 threadedly connected to the connecting seats 8. In use, through the interaction of the box body 1, through holes 3, wiring sealing assembly 4, cover plate 5 and sealing strip 6, the aviation plug-specific junction box can achieve better sealing performance during use, improve the safety of the junction box, and thus facilitate better practicality. Mounting plates 24 are fixedly installed at both ends of the box 1. Mounting slots 25 are opened through the interior of the two mounting plates 24 at the ends that are far apart from each other. During use, the interaction between the mounting plates 24 and the mounting slots 25 makes it easier to fix the entire junction box during use, which is convenient to operate and ensures the stability of the junction box during use. The wiring sealing assembly 4 includes a wiring tube 9, which is fixedly installed inside the through hole 3. One end of the wiring tube 9 is located inside the housing 1, and the other end extends to the outside of the housing 1. The length of the end of the wiring tube 9 outside the housing 1 is greater than the length of the end of the wiring tube 9 inside the housing 1. An external threaded sleeve 10 is fixedly installed outside the housing 1 and outside the wiring tube 9. An internal threaded movable ring 11 is threadedly installed on the outer side of the external threaded sleeve 10 away from the housing 1. A limit stop ring 23 is fixedly installed on the outer side of the external threaded sleeve 10 away from the internal threaded movable ring 11. The diameter of the limit stop ring 23 is greater than the diameter of the internal threaded movable ring 11. First connecting blocks 12 are symmetrically fixedly installed on the outer side of the internal threaded movable ring 11. The two first connecting blocks 12 are located away from the internal threaded movable ring 11. A connecting strip 13 is fixedly installed on one side of the moving ring 11. A second connecting block 14 is fixedly installed on the end of each of the two connecting strips 13 away from the first connecting block 12. A connecting bearing 15 is fixedly installed between the two second connecting blocks 14. A circular movable block 16 is rotatably installed inside the connecting bearing 15. A circular hole 17 is opened through the inside of the circular movable block 16. A conical rubber block 18 is fixedly installed on the side of the circular movable block 16 near the cable conduit 9. A wire hole 19 is opened through the inside of the conical rubber block 18. One end of the wire hole 19 is connected to the circular hole 17. A third connecting block 20 is fixedly installed in the middle of the side of the two connecting strips 13 away from each other. An adjusting ring 21 is fixedly installed on the outside of the third connecting block 20. Anti-slip protrusions 22 are evenly fixedly installed on the outside of the adjusting ring 21.

[0014] Working principle: During operation, the cable is first inserted through the circular hole 17 inside the circular movable block 16 into the wire hole 19 inside the conical rubber block 18, and then extended through the cable conduit 9 into the interior of the housing 1. Then, the adjusting ring 21 is rotated, which drives the connecting strip 13 to rotate via the third connecting block 20. The connecting strip 13 drives the internal thread movable ring 11 to rotate outside the external thread sleeve 10 via the first connecting block 12. The internal thread movable ring 11 rotates and moves, driving the first connecting block 12 to move. The first connecting block 12 drives the connecting strip 13 to move, which in turn drives the second connecting block 14 to move. The second connecting block 14 drives the connecting bearing 15 to move, which in turn drives the circular movable block 16 to move. The circular movable block 16 then drives the conical rubber block 18 to move, with one end of the conical rubber block 18 inserted into the end of the cable conduit 9 located outside the housing 1. As the conical rubber block 18 is inserted, it seals the inside of the end of the cable tray 9 located outside the box 1. Simultaneously, the conical rubber block 18 contracts under the pressure of the cable tray 9 during movement, sealing the cable inside the cable hole 19. Then, the adjustment ring 21 stops rotating. After the five cable sealing components 4 have sealed the cables, the ends of the five cables are connected to the terminal block assembly 2. The cover plate 5 is then placed on top of the box 1 and fixed to the top of the box 1 using four connecting bolts 7. After fixing, the sealing strip 6 seals the space between the cover plate 5 and the inside of the top of the box 1. Then, mounting bolts matching the size of the mounting groove 25 are used to fix the mounting plate 24, thus achieving a fixed installation of the entire junction box. This ensures better sealing during use of the aviation plug-specific junction box, improving the safety of the junction box and facilitating better practicality.
