Description

Technical Field

[0001] The utility model relates to the field of water gun connectors, in particular to a high-stability fire-fighting water gun connector. 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 existing fire hose clamps have poor holding stability and fastening stability. The impact force of the high-pressure water flow in the fire hydrant entering the fire hose for the first time is relatively large, which makes it difficult for firefighters to grasp and control the fire hose well, which easily causes the fire hose to slip out of their hands. At the same time, the huge impact force of the water flow makes it easy for the joint between the fire hose and the fire hose to fall off, resulting in the inability to carry out normal firefighting work and the inability to effectively control the fire. Therefore, it is urgent to develop a high-stability fire hose clamp that can reduce the impact force when the high-pressure water flow enters the fire hose and improve the holding stability and fastening stability. Utility Model Content

[0022] Working principle:

[0023] The fire gun head is fixedly connected to the gun buckle body 1 through a thread. When in use, the gun buckle body 1 is buckled with the connecting sleeve at one end of the fire hose through the buckle pipe tooth 12 set on one side of the buckle shaft section 11; when the high-pressure water flow flows out from the fire hydrant and enters the fire hose gun buckle body 1, the high-pressure water flow first impacts the buffer baffle 53 of the buffer structure 5 in the central through hole of the gun buckle body 1, and the buffer baffle 53 is impacted by the high-pressure water flow and moves in the flow direction of the high-pressure water flow. The buffer baffle 53 is buffered by the buffer spring 54. The buffer baffle 53 and the buffer spring 54 play a role of buffering and stabilizing the high-pressure water flow, preventing the impact force of the water flow from being too large when the high-pressure water flow enters the gun buckle body 1, causing the gun buckle body 1 and the fire hose to fall off and cause leakage; then the water flows from the water outlet set on the buffer baffle 53 into the central water hole of the mounting sleeve 51, enters the fire gun head through the water hole, and finally sprays out through the fire gun head to extinguish the fire.

[0024] The buffer structure 5 provided in the gun buckle body 1 is used to buffer and stabilize the high-pressure water flow that first enters the fire hose, thereby improving the buckle stability of the fire hose. At the same time, a gripping rod 3 is provided on the outer diameter surface of the gun buckle body 1. When performing fire-fighting operations, firefighters can grasp the gripping rod 3 for use, thereby improving the stability of the firefighter's grip and preventing the fire hose from slipping out of their hands due to the huge impact force during water jetting.
