It has the advantages of long range and large water volume. According to different jet forms and characteristics, it can be divided into: direct current water gun, spray water gun, multi-purpose water gun, etc.; the existing direct current water gun is composed of a water gun head and a water gun buckle, and the connection between the two is threaded connection or interlocking sleeve connection. When the threaded water gun buckle is connected to the water gun head, in order to prevent water from seeping out, it is necessary to wrap a sealing tape at the connection, which is inconvenient. In the process of repeated disassembly and assembly of the fire gun, the threaded connection part is easy to wear and leak, resulting in unstable water flow delivery, which reduces the use effect of the fire gun; therefore, it is urgent to develop a fire gun buckle that can tightly connect the fire gun head with the gun buckle body, improve the sealing effect to prevent water leakage, and ensure the stable water flow delivery effect of the fire gun.

[0006] Furthermore, one end of the mating shaft section of the fire gun head is provided with an inclined taper, and one end of the corresponding mating hole provided on the central water hole of the gun buckle body is also provided with an inclined taper that matches the mating shaft section; the sealing effect of the mating shaft section and the mating hole is improved to prevent water leakage, and at the same time facilitates the installation and connection between the gun buckle body and the fire gun head.

[0007] Furthermore, the outer diameter surface of the matching shaft section of the fire gun head is coated with a sealing rubber layer to improve the sealing fit between the matching shaft section of the fire gun head and the matching hole at one end of the water hole of the gun buckle body to prevent water leakage.

[0008] Furthermore, the outer diameter surface of the connecting sleeve is provided with anti-skid patterns, so that the user can easily rotate the connecting sleeve to connect and fix the gun buckle body and the fire gun head.

[0015] The utility model is further described below in conjunction with the accompanying drawings: Example

[0016] A fire gun buckle that stably delivers water flow, such as Figure 1-3As shown, it comprises a gun buckle body 1, one end of which is provided with a buckle shaft section 11 for fixing and buckling with a fire hose; a threaded shaft section 13 is provided on the outer diameter surface of the end of the gun buckle body 1 away from the buckle shaft section 11; a water hole 12 is provided at the center of the gun buckle body 1, and a matching hole is provided at one end of the water hole 12 close to the threaded shaft section 13; a fire gun head 2 is provided on the side of the gun buckle body 1 away from the buckle shaft section 11, and a fire gun head 2 is provided on the end close to the gun buckle body 1 A mating shaft section 21 is sealed and matched with the mating hole provided at one end of the central water hole 12 of the gun buckle body 1; a connecting sleeve 3 is also provided on the side of the gun buckle body 1 close to the fire gun head 2, and a threaded hole is provided on the end of the connecting sleeve 3 close to the gun buckle body 1 to mesh with the threaded shaft section 13 provided on the gun buckle body 1; a shoulder is provided on the end of the connecting sleeve 3 close to the fire gun head 2 for limiting the position of the mating shaft section 21 of the fire gun head 2; the fire gun head 2 is fixedly connected to the gun buckle body 1 through the connecting sleeve 3.

[0017] Working principle:

[0018] When installing the fire-fighting water gun connector of the utility model, the matching shaft section 21 of the fire-fighting gun head 2 is aligned with the matching hole provided on one side of the central water hole 12 of the gun buckle body 1, and then the matching shaft section 21 of the fire-fighting gun head 2 is pushed into the matching hole provided on one side of the central water hole 12 of the gun buckle body 1; the matching shaft section 21 of the fire-fighting gun head 2 is sealed and matched with the matching hole provided on one side of the central water hole 12 of the gun buckle body 1; then the connecting sleeve 3 is rotated to make the threaded hole provided on the connecting sleeve 3 mesh with the threaded shaft section 13 provided on the gun buckle body 1. When the connecting sleeve 3 is rotated, the connecting sleeve 3 will move toward the side of the gun buckle body 1 as the threads are meshed, and the shaft shoulder provided at one end of the connecting sleeve 3 will press the matching shaft section 21 of the fire-fighting gun head 2 toward the side of the gun buckle body 1, so that the fire-fighting gun head 2 is tightly connected with the gun buckle body 1.
