[0018] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0019] like Figure 1 As shown, the utility model provides a high-strength aluminum casting for firefighting, comprising a water gun buckle body 1 and a threaded groove 2 provided on the top inner side of the water gun buckle body 1, wherein the water gun buckle body 1 is made of aluminum alloy;

[0020] When in use, the water gun buckle body 1 is connected to the fire water gun in a threaded connection manner through the threaded groove 2, and on the contrary, the inner bottom of the water gun needs to pre-open an annular groove corresponding to the support ring 3 and the support rod 4, and the other end of the water gun buckle body 1 away from the fire water gun is connected to the buckle on the fire hose, thereby completing the connection between the fire hose and the fire water gun. When extinguishing a fire, the water gun buckle body 1 is used to transport fire water. It has the advantage of being lightweight and more convenient to carry and use.

[0021] like Figures 1 to 3As shown, in this embodiment, a protective layer 5 is provided on the water gun buckle body 1, a support ring 3 is built in the thread groove 2, and the bottom of the support ring 3 is an integrated structure with a plurality of support rods 4, and the end of the support rod 4 away from the support ring 3 is integrally connected with the bottom of the inner side of the thread groove 2 to cooperate with the support ring 3 to provide auxiliary support for the water gun buckle body 1;

[0022] The protective layer 5 includes a silicate protective layer 51, an epoxy resin layer 52 and a zirconium oxide protective layer 53 which are arranged on the outer surface of the water gun buckle body 1 from the inside to the outside, and is used to provide auxiliary protection for the water gun buckle body 1 to strengthen the water gun buckle;

[0023] In this embodiment, the protective layer 5 also includes a nano silicon carbide protective layer 54 arranged on the inner circle of the water gun buckle body 1, which improves the impact resistance of the water gun buckle body 1, makes the inner wall of the water gun buckle body 1 smoother, and reduces the water flow resistance;

[0024] Among them, a spacing is set between the side surface of the support ring 3 and the inner circle of the thread groove 2, and the thread groove 2 and the support ring 3 are arranged in concentric circles, which is conducive to the support ring 3 being stably attached to the inner wall of the water gun;

[0025] Among them, the support rods 4 on the support ring 3 are distributed in an annular shape with equal intervals, providing stable auxiliary support for the support ring 3;

[0026] Among them, the top surface of the support ring 3 is lower than the top surface of the water gun buckle body 1, so that the support ring 3 can provide stable auxiliary support for the water gun buckle body 1;

[0027] In this embodiment, the support rod 4 on the support ring 3 extends outwardly from top to bottom, thereby increasing the stability of the support rod 4;

[0028] When in use, during the installation of the water gun buckle body 1, the support ring 3 is fitted onto the inner side of the annular groove opened on the inner wall of the water gun, and the support ring 3 cooperates with the support rod 4 to provide auxiliary support for the water gun buckle body 1.
