AI Technical Summary
The existing threaded connection method of explosion-proof junction boxes is inefficient and can easily cause the cable protection tube to twist and entangle, affecting cable operation.
The structure employs a sliding cylinder and trapezoidal insert, utilizing spring rebound force to achieve quick connection and separation of the cable protection tube. The threaded ring slides within the sliding cylinder to prevent twisting and entanglement, and the sealing design enhances the airtightness.
It enables quick connection and disassembly of cable protection tubes, prevents twisting and tangling, improves operational efficiency and sealing performance, and enhances the practicality of cable operation.

Abstract
Claims
1. An explosion-proof cable entry box with anti-entanglement, comprising an explosion-proof cable entry box (1), characterized in that: Both ends of the explosion-proof wiring box (1) are fixedly connected to wiring ports (2). A sliding cylinder (3) is slidably connected inside the wiring port (2). Springs (4) are snapped into both sides inside the wiring port (2). Trapezoidal plugs (5) are welded to the ends of the two springs (4) that are close to each other. Slots (6) for inserting into the trapezoidal plugs (5) are opened on both sides of the surface of the sliding cylinder (3). A pull rod (7) that is slidably connected to the wiring port (2) is welded to the side of the trapezoidal plug (5) away from the sliding cylinder (3). The springs (4) are sleeved on the surface of the pull rod (7).
2. An explosion-proof cable entry according to claim 1, characterized in that: The end of the sliding cylinder (3) away from the explosion-proof cable box (1) is rotatably connected to a threaded ring (8), and a T-shaped slider (9) that is slidably connected to the sliding cylinder (3) is welded to the surface of the threaded ring (8).
3. An explosion-proof cable entry according to claim 1, characterized in that: The explosion-proof wiring box (1) is provided with a cover plate (10) on the top. Both ends of the cover plate (10) are threadedly connected with connecting bolts (11). Threaded holes (12) are provided on both sides of the top of the explosion-proof wiring box (1) and are threadedly connected to the connecting bolts (11).
4. An anti-winding explosion-proof terminal box according to claim 3, characterized in that: A sealing gasket (13) is provided between the explosion-proof junction box (1) and the cover plate (10) and is engaged with the cover plate (10).
5. An explosion-proof cable entry boot according to claim 1, wherein: The end of the pull rod (7) away from the trapezoidal plug (5) is welded with a rotating bolt (14) that is rotatably connected to the threading port (2).
6. An explosion-proof cable entry boot according to claim 1, wherein: The end of the threading port (2) near the sliding cylinder (3) is fitted with a sealing ring (15), and the surface of the sliding cylinder (3) is provided with an extrusion groove (16) that works in conjunction with the sealing ring (15).
7. An explosion-proof cable entry according to claim 5, characterized in that: The surfaces of the sliding cylinder (3), the threaded ring (8), and the rotating bolt (14) are all provided with anti-slip stripes.
