Through the setting of the sealing groove 3, the sealing assembly 4 and the pressure-stabilizing hollow tube 7, when the fire hose interface is in use, the water pressure generated by the high pressure reaches the pressure-stabilizing hollow tube 7 to reduce the impact force and maintain a stable pressure. At the same time, the spring washer 401 can provide continuous axial elastic force to compensate for the decrease in sealing performance caused by water pressure fluctuations. The spring washer 401 will deform appropriately to enhance the seal and avoid crushing, which helps to maintain the stability of water flow and improve the reliability of the interface seal.
[0028] The fastening assembly 9 includes a lower clamping component 901, an upper clamping component 902, a rotating ball 903, a fixing component 904, and a locking component 905.

The lower clamping component 901 and the upper clamping component 902 are then clamped onto them, the fixing component 904 is clamped into the slot 12, and the locking component 905 is tightened to secure them. This prevents the fire hoses from falling off the interface, avoiding the common use of elastic clamps for fixing, which could cause them to fall off if the water pressure increases. This helps improve the explosion-proof function of the interface and increases the safety of its use.
[0029] The sealing assembly 4 includes a spring gasket 401 disposed inside the sealing groove 3, and a sealing gasket 402 disposed on one side of the spring gasket 401. The sealing assembly 4 is designed to deform the spring gasket 401 under high pressure to enhance the seal and prevent crushing.
[0030] One end of the sealing gasket 402 is inserted into the middle of one end of the A interface 1. The sealing gasket 402 is made of high compression ratio rubber. The sealing gasket 402 plays a sealing role.
[0031] Two buckles 10 are fixedly connected to the outer periphery of both interface component A 1 and interface component B 2. A strip 11 is fixedly connected to the edge of one end of interface component A 1 and interface component B 2. The width inside the buckle 10 matches the thickness of the strip 11. The setting of the strip 11 and buckle 10 achieves the function of quick connection.
[0032] The fastening assembly 9 includes a lower clamping part 901 that is sleeved on the outside of the protective cloth 8. One end of the lower clamping part 901 is rotatably connected to an upper clamping part 902 via a connecting rod.

[0034] One end of the clamping upper part 902 is provided with a slot 12, which is adapted to the fixing part 904. The slot 12 serves as a connection.
[0035] In this invention, the working steps of the device are as follows:
[0036] First step: When using, connect one end of each of the two fire hoses to the first connecting pipe 5 and the second connecting pipe 6 with iron wire. Then, wrap the protective cloth 8 around the outside of the fire hoses and the first connecting pipe 5 and the second connecting pipe 6. Then, clamp the lower clamping piece 901 and the upper clamping piece 902 on top, clamp the fixing piece 904 in the slot 12, and tighten the locking piece 905 to fix it.
[0037] The second step: When the fire hose is in use, the high pressure generated by the water reaches the pressure stabilizing hollow tube 7 to reduce the impact force and maintain a stable pressure. At the same time, the spring washer 401 can provide continuous axial elasticity to compensate for the decrease in sealing caused by water pressure fluctuations. The spring washer 401 will deform appropriately to enhance the seal and prevent crushing.
