Description
Technical Field
[0001] The utility model belongs to the technical field of fire-fighting equipment, and specifically relates to an internal snap-in leak-proof interface for a fire hose. Background Art
[0002] A fire hose is a hose used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber lining and are wrapped with linen fabric on the outer surface, while advanced fire hoses are made of polymeric materials such as polyurethane.
[0003] Both ends of the fire hose have metal connectors, which can be connected to another hose to extend the distance or to a nozzle to increase the liquid spraying pressure. Currently, when connecting the fire hose to the water pump connector, a clamp is usually used for fixation. However, if only relying on the clamp to fix when transporting high-pressure water or foam, the hose may slide on the interface, and the connection between the hose and the interface is not stable enough, resulting in a risk that the hose may fall off from the water pump interface, and there may also be a problem of leakage of high-pressure water flow at the connection between the interface and the hose.
[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

An annular snap-in groove is opened on one side of the internal snap-in seat. The hose connector is snap-connected inside the annular snap-in groove. Moving grooves are opened on both the left and right sides of the hose connector. Wedge-shaped limit blocks are slidably connected to the inner walls of one sides of the two moving grooves. Symmetrically arranged limit grooves are opened on the inner walls of the opposite sides of the annular snap-in groove. The two limit blocks are respectively snap-connected to the inner walls of the two limit grooves. Connecting plates are slidably connected to the inner walls of one sides of the two moving grooves. One sides of the two connecting plates are respectively fixedly connected to the outer walls of one sides of the two limit blocks. Connecting springs are installed on the inner walls of one sides of the two moving grooves. One ends of the two connecting springs are respectively fixedly connected to the outer walls of one sides of the two connecting plates.
[0007] As a preferred embodiment of the present utility model, a second connecting pipe is fixedly installed in the middle of one side of the internal snap-in seat, and the opposite ends of the hose and the second connecting pipe are in contact.
[0008] As a preferred embodiment of the present utility model, the first connecting pipe is sleeved on the outer wall of the second connecting pipe, and a clamp is provided outside the first connecting pipe.
[0009] As a preferred embodiment of the present utility model, symmetrical movable holes are provided on the left and right sides of the inner buckle seat, and the two movable holes communicate with the two limiting grooves respectively.
[0010] As a preferred embodiment of the present utility model, piston plates are slidably connected to the inner walls of the two movable holes.

When connecting the hose 2 and the water pump connector 1, first insert the hose connector 5 at the end of the hose 2 into the annular snap-in groove 8 provided on one side of the internal snap-in seat 3, so that the two limiting blocks 11 can move into the two limiting grooves 12 under the action of the two moving grooves 10, the two connecting plates 13 and the two connecting springs 14, realizing the limiting effect on the hose connector 5, so that the hose connector 5 can be stably connected to the internal snap-in seat 3, and thus the hose 2 can be stably connected to the water pump connector 1.
[0024] In the specific embodiment, a second connecting pipe 9 is fixedly installed in the middle of one side of the internal snap-in seat 3. The opposite ends of the hose 2 and the second connecting pipe 9 are in contact. The first connecting pipe 4 is sleeved on the outer wall of the second connecting pipe 9.
