Description

Technical Field

[0001] The utility model relates to a fire-fighting water gun, in particular to a fire-fighting water gun for firefighting. Background Art

[0002] The fine water mist fire gun uses a high-pressure water source to spray water into tiny "fog" droplets. The small mist particles can quickly drift around the fixed fire source and effectively control the spread of the fire. It is more commonly used in sudden fire situations such as home environments or factory environments. However, in many cases, the lighting conditions in the fire environment are not good. If the firefighting personnel cannot find and wear explosion-proof headlights in time, they will not be able to see the situation around the fire source, such as the charging interface. Once the fire-fighting water source is sprayed to dangerous locations such as the charging interface, it is easy to have an adverse effect on the control of the spread of the fire and affect the effectiveness of the firefighting water gun.

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The utility model discloses a fire-fighting water gun, the structure of which is arranged as follows Figure 1As shown, it includes a main pipe 2, and a ball valve 1 is connected to the water inlet end of the main pipe 2, and the ball valve 1 is used for regulating the water volume and opening and closing control; a water inlet connector 11 is fixedly connected to the water inlet end of the ball valve 1, and the water inlet connector 11 is used for access to a high-pressure water source.

[0024] The water outlet end of the main pipe 2 is connected to a pressurized thin water pipe 3. High-pressure water enters the pressurized thin water pipe 3 through the main pipe 2. The diameter of the pressurized thin water pipe 3 is reduced, so that the high-pressure water is further pressurized and finally sprayed out from the atomizing nozzle 5 installed at the front end of the water outlet of the pressurized thin water pipe 3 in the form of tiny "mist" water droplets.

[0025] Considering that fires occur suddenly in home or factory environments, if the lighting in the fire environment is poor and the firefighters cannot find a wearable explosion-proof headlamp in time, the firefighting process will be affected. The firefighting water gun disclosed in the present invention is provided with an explosion-proof lighting flashlight 4 at the pressurized water pipe 3. The explosion-proof lighting flashlight 4 is detachably assembled above the pressurized water pipe 3 through a locking assembly 6 and can be used for lighting.

[0026] The structure of explosion-proof lighting flashlight 4 is as follows Figure 3 As shown, a finished explosion-proof flashlight can be used, which has explosion-proof and waterproof properties. In order to make the explosion-proof lighting flashlight 4 universally assembled on the pressurized capillary water pipe 3, a locking component 6 is specially designed. The structural arrangement of the locking component 6 is as follows Figure 2 As shown, it includes a clamping body in a clamp-type structure, the clamping body has a cylindrical sleeve 61 and a clamping piece 62 extending from an opening of a side wall of the cylindrical sleeve 61;

[0027] Among them, the cylindrical sleeve 61 is adapted to the shell of the explosion-proof lighting flashlight 4, and the clamping groove 63 adapted to the pressurized thin water pipe 3 is stamped on the clip 62. After the cylindrical sleeve 61 clamps the shell of the explosion-proof lighting flashlight 4 and the clamping groove 63 is clamped on the pressurized thin water pipe 3, the fixing bolts are locked to achieve fixation.

[0028] The fixing bolts are divided into an upper locking bolt 64 and a lower locking bolt 65, wherein the upper locking bolt 64 is located on the clip between the cylindrical sleeve 61 and the clamping groove 63, and the lower locking bolt 65 is located on the clip below the clamping groove 63. After the upper locking bolt 64 is tightened, the side opening of the cylindrical sleeve 61 and the upper side opening of the clamping groove 63 are tightened and shrunk, and the lower locking bolt 65 tightens and shrinks the lower side opening of the clamping groove 63, so that the explosion-proof lighting flashlight 4 is fixedly assembled above the pressurized capillary water pipe 3.

[0029] As a preferred embodiment, in order to facilitate the holding and use of the fire hose, a front handle 8 distributed in a vertical state is assembled on the main pipe 2, and a rear handle 9 distributed in an inclined state is assembled under the valve body of the ball valve 1. The handles distributed in front and behind allow the firefighter to hold the fire hose with both hands to better resist the recoil when spraying water.

[0030] The front handle 8 is assembled and connected with the main body tube 2 through a fixing bracket 7; screws are symmetrically welded on both sides of the main body tube 2, and the fixing bracket 7 is installed on the screws and locked with the screws through a fixing nut.

[0031] As for the rear handle 9, it is assembled under the valve body of the ball valve 1 through the elbow joint 10; Figure 4 As shown, a through hole 12 is opened at the top plane of the bent joint 10 of the rear handle 9, and a limiting hanging column 13 is passed through the through hole 12. The limiting hanging column 13 is welded to the valve body of the ball valve 1.

[0032] In summary, it can be seen that for the fire-fighting water gun disclosed by the utility model, on the basis of the structure of the existing fine water mist fire-fighting water gun, an explosion-proof lighting flashlight is combined with the pressurized fine water pipe of the fire-fighting water gun. The explosion-proof lighting flashlight is used as a lighting tool. It is suitable for extinguishing small fire sources and in poor lighting conditions. It can assist fire-fighting personnel to better see the environment around the fire point, thereby ensuring that fire extinguishing can be carried out accurately and efficiently, so as to reduce the temperature of the fire source and achieve the purpose of extinguishing the fire.

[0033] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
