Description

Technical Field

[0001] The utility model relates to the field of water gun buckles, in particular to an anti-dropping type water gun buckle. Background Art

[0002] Fire hose is one of the more common fire-fighting tools. When connected to a fire hose or a fire truck, it can spray out dense and substantial water flow. Commonly used fire hoses include direct current hoses and spray hoses. Regardless of the type of hose, the hose and the water hose are locked together using a fire hose buckle.

[0003] The connection between the existing water gun buckle and the water hose buckle generally adopts a rotating combination method. When in use, they need to be aligned and connected first and then rotated to position the two. This connection method is not reliable enough. In actual use, when firefighters hold water guns for firefighting, a slight twist will cause the water gun buckle parts to reverse and disengage, which will cause emergencies and easily cause casualties to firefighters. Its safety and practicality need to be improved. Therefore, it is urgent to develop an anti-detachment water gun buckle that can prevent the excessive impact of water flow or the firefighter's accidental twisting from causing the buckle parts of the gun buckle body to reverse and disengage, thereby improving safety and stability of use. Utility Model Content

[0004] In order to overcome the shortcomings of the existing water gun connector and the water hose connector, which generally adopt a rotational combination method, the connection reliability is insufficient, and the water gun buckle component will be reversed and disengaged if slightly twisted, the technical problem to be solved by the utility model is to provide an anti-detachment water gun connector that can prevent the excessive water flow impact force or the firefighter's accidental twisting from causing the gun buckle main body buckle component to be reversed and disengaged, thereby improving safety and stability in use.

[0005] The utility model is achieved by the following specific technical means:

[0008] Furthermore, the clamping shaft extends through and to one end outside the baffle and is provided with an arc-shaped ball head, so that the clamping shaft can be grasped and stretched toward both sides.

[0009] Furthermore, the mounting hole provided in the center of the protrusion has a smaller aperture near the end of the collar than the end away from the collar, and the mounting hole is in a stepped hole shape; this prevents the card shaft from escaping from the mounting hole provided in the protrusion and serves to limit the card shaft.

[0010] Furthermore, two protrusions are provided on the outer diameter surface of the ring, and the two protrusions are equidistantly arranged relative to each other. Two corresponding clamping shafts are also provided, which are respectively slidably arranged in the mounting holes provided by the two protrusions; at the same time, two clamping holes are also provided on the outer diameter surface of the buckle shaft section relative to the two clamping shafts; the two buckle pipe teeth on the fire hose buckle are respectively limited and clamped to improve the clamping effect and clamping strength.

[0022] Working principle:

[0023] The fire gun body 2 is fixedly connected to the gun buckle body 1 through a thread. When in use, the gun buckle body 1 is buckled with the buckle on the fire hose through the buckle pipe thread 13; the pipe thread of the buckle on the fire hose is snapped into the buckle groove 12; then the snap-in structure 3 sleeved on the outer diameter surface of the gun buckle body 1 is rotated, and when the mounting holes set in the centers of the two protrusions 32 on the outer diameter surface of the ring 31 are aligned with the two snap-in holes 14 set on the outer diameter surface of the snap-in shaft section 11, the snap-in shaft 33 slidingly arranged in the mounting hole pops out under the action of the spring 34, and the snap-in shaft 33 extends out of the mounting hole and snaps into the snap-in hole 14 set on the snap-in shaft section 11; the snap-in shaft 33 passes through the snap-in groove and extends into the buckle groove 12 of the snap-in shaft section 11, limiting the pipe thread of the fire hose buckle, thereby circumferentially limiting the fire hose buckle, preventing the buckle component of the gun buckle body 1 from reversing and disengaging due to excessive water flow or accidental twisting by firefighters, thereby improving safety and stability in use.
