[0019] Figure 3 It is a schematic diagram of the cut-open structure of the rotating frame in the embodiment of the present utility model. Detailed Description of the Embodiment
[0020] The following combines the drawings and embodiments to further describe the specific implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.
[0021] As Figures 1-3 shown, the fire fighting water gun includes a water gun body 5, a fixed seat 1, and a U-shaped rotating frame 4. A fixed rod 2 is provided on the fixed seat 1. A connecting rod 3 is penetrated through the fixed rod 2. The water gun body 5 is arranged on the connecting rod 3. The rotating frame 4 is rotatably arranged at the end of the connecting rod 3. Rotating shafts 6 are rotatably arranged at both ends of the rotating frame 4. Both sides of the water gun body 5 are connected to the rotating shafts 6. An adjusting device for adjusting the height of the water gun is provided between the fixed rod 2 and the connecting rod 3.
[0022] Specifically, the adjusting device includes an adjusting rod 9 and a sliding block 11. A fixing sleeve 10 is provided on the fixing rod 2. The adjusting rod 9 is slidably inserted through the fixing sleeve 10. A fixing channel 7 is formed in the connecting rod 3 from top to bottom. One end of the adjusting rod 9 is inserted into the fixing channel 7. The sliding block 11 is slidably disposed within the fixing sleeve 10. The sliding block 11 is disposed on the fixing rod 2. A spring 12 is provided within the fixing sleeve 10. The other end of the adjusting rod 9 extends out of the fixing sleeve 10. Among them, when using the water gun, directly connect the water gun to the water hose, place the fixing base 1 on the ground, then pull the adjusting rod 9, pull out the connecting rod 3 to a height suitable for the staff to operate the water gun, and then release the adjusting rod 9, so that the adjusting rod 9 slides into the fixing channel 7 and engages. Then the staff can directly operate the water gun to spray water without having to hold the fire water gun anymore, which greatly facilitates the operation of the staff, enables the staff to carry out firefighting for a long time, and only requires a single person to operate, which is very convenient.
[0023] In order to be able to adjust the spraying angle and thus spray water better, a drive box 13 is further included. The drive box 13 is disposed on the side of the rotating frame 4.
