Technical Field

[0001] The utility model relates to the field of fire-fighting equipment, in particular to a fire-fighting water gun fixing device. Background Art

[0002] Fire hoses are the terminal tools used to spray fire extinguishing agents during firefighting. Connected to fire hoses, they offer advantages such as long range, high water volume, and adjustable spray flow. Based on the jet form and function, they are mainly categorized into direct current, spray, water curtain, foam, and multi-function nozzles.

[0003] During firefighting operations, a water gun is sometimes required to continuously spray a fixed location, which requires firefighters to hold the water gun at their work locations all the time, consuming their physical strength.

[0009] Preferably, the second rotation drive mechanism includes a second, meshing worm gear and a second worm gear, both rotatably mounted on the outside of the riser. The second worm gear is connected to a second output shaft, which passes through the riser and is fixedly connected to the pitch adjustment base. One end of the second worm gear is connected to a second drive motor, which is connected to a remote control signal. The worm gear mechanism drives pan and tilt, resulting in a high speed ratio, smooth rotation, and self-locking capability, ensuring a more stable position of the water gun.

[0010] Preferably, the pitch adjustment seat includes a fixing ring, which is used to surround and fix the fire hose, and connecting rods are provided at both ends of the fixing ring, and the connecting rods on both sides are rotatably mounted on the two vertical plates respectively.
