When connecting, the protruding ring 308 on the first rubber ring 305 is aligned with the first groove 309 on the second rubber ring 306. The two circular rings 301 are tightly connected to prevent water leakage. The elastic force generated by the honeycomb rubber ring 307 can make the connection between the first rubber ring 305 and the second rubber ring 306 even tighter.

[0031] In one embodiment, Figure 4 When the cam 314 is in the unlocking state, the locking plate 312 is locked and the locking plate 314 is locked, so that the cam 314 can be unlocked and the lock 302 can be unlocked.

[0032] In one embodiment, a slot is provided on the surface of the wedge block 303 , which matches the slot of the block 314 on the locking block 302 . When the locking block 302 slides to a specified position along the wedge block 303 , the block 314 will be stuck in the slot on the surface of the wedge block 303 .

[0033] In one embodiment, Figure 1 As shown, the installation mechanism 400 includes a hose 401, a guide member 402 and a tie clamp 404. There are six guide members 402 in total, which are evenly distributed on the outside of the ring 301. The hose 401 is fixed on the inside of the guide member 402. Two tie clamps 404 are arranged on the outside of the guide member 402. The tie clamp 404 is fixed to the outside of the guide member 402 by a limit member 403. When connecting, the fire-fighting pipe is put on the first connecting pipe 100 and the second connecting pipe 200, and the fire-fighting pipe is extended into the hose 401 along the guide member 402, and then the fire-fighting pipe is fixed by the tie clamp 404.

[0034] In one embodiment, Figure 5 As shown, the fastening knob 500 includes a mounting seat 501, a winding wheel 505, a rotating wheel 507 and a knob cover 511. The mounting seat 501 is fixed to the outside of the guide member 402. A baffle 502 is provided inside the mounting seat 501. The winding wheel 505 is provided below the baffle 502. The rotating wheel 507 is provided above the baffle 502. The knob cover 511 is fixed above the rotating wheel 507. When in use, the rotating wheel 507 is driven to rotate by rotating the knob cover 511, and the rotating wheel 507 drives the winding wheel 505 to rotate.

[0035] In one embodiment, Figure 5As shown, a first tooth groove 503 is provided on the inner wall of the mounting seat 501, and the first tooth groove 503 is located at the upper end of the baffle 502. Two wire inlets 504 are symmetrically provided at the lower end of the mounting seat 501. A connecting end 506 with a convex tooth is provided at the top of the winding wheel 505. The convex tooth on the connecting end 506 matches the second tooth groove 510 on the rotating wheel 507. An elastic arm 508 is provided on the outer side of the rotating wheel 507. A limiting tooth 509 is provided on the outer side of the elastic arm 508. The limiting tooth 509 matches the first tooth groove 503 in the mounting seat 501. When in use, one end of the tie hoop 404 is fixed to the winding wheel 505 through the wire inlet 504, and the other end of the tie hoop 404 is fixed to On the outside of the mounting seat 501, the rotating knob cover 511 drives the rotating wheel 507 to rotate, and the rotating wheel 507 drives the winding wheel 505 to rotate, and the winding wheel 505 drives the binding hoop 404 to tighten. The limiting teeth 509 on the outside of the rotating wheel 507 interact with the first tooth groove 503 on the mounting seat 501, so that the rotating wheel 507 can only rotate in one direction. When the binding hoop 404 needs to be loosened, the knob cover 511 is lifted upward, and the rotating wheel 507 moves upward with the knob cover 511, so that the limiting teeth 509 on the outside of the rotating wheel 507 disengage from the first tooth groove 503 on the mounting seat 501, so that the rotating wheel 507 can rotate in the opposite direction to loosen the binding hoop 404.

[0036] The above embodiment discloses a fire-fighting pipe connection interface. When in use, the fire-fighting pipe is connected to the first connecting pipe 100 and the second connecting pipe 200 respectively, and then the knob cover 511 is rotated to drive the winding wheel 505 to tighten the tie 404 to firmly connect the fire-fighting pipe with the first connecting pipe 100 and the second connecting pipe 200. Then, the rings 301 on the first connecting pipe 100 and the second connecting pipe 200 are docked. When docking, the convex ring 308 on the first rubber ring 305 is aligned with the first groove 309 on the second rubber ring 306. The two rings 301 are tightly connected. Then, the ring 301 is rotated so that the locking block 302 on the ring 301 moves along the wedge. When the block 303 slides, and the locking block 302 slides to the specified position along the wedge block 303, the blocking block 314 on the locking block 302 will automatically be stuck in the blocking groove on the surface of the wedge block 303, completing the connection of the fire pipe; when the interface needs to be loosened, the button 315 on the locking block 302 is pressed, and the ring 301 is rotated at the same time to separate the locking block 302 from the wedge block 303; when the fire pipe needs to be removed, the knob cover 511 is lifted upward, and the rotating wheel 507 moves upward with the knob cover 511, so that the limiting tooth 509 on the outer side of the rotating wheel 507 is separated from the first tooth groove 503 on the mounting seat 501, and the rotating wheel 507 is rotated in the opposite direction to loosen the tie clamp 404, and then the fire pipe is pulled out.

[0037] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
