Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a fire fighting water gun with high stability. Background Art

[0002] As the name suggests, a fire pump is a pump used in firefighting. Fire pumps are imported products and are divided into different types according to different classification methods. With its fully sealed, leak-free and corrosion-resistant characteristics, it is widely used in environmental protection, water treatment, firefighting and other departments. It is used to pump various liquids and spray them through a fire hose. However, as the pressure of the fire pump continues to increase, the impact force of the water flow sprayed from the fire hose is greater, so there will be a greater recoil and the stability is extremely poor.

[0003] Existing fire hoses are often of a single structure, and usually multiple support components are provided to disperse the impact force to the firefighters. For example, patent number CN220237624U, entitled "A Fire Hose", installs multiple support components on the spray gun body, so that part of the impact force is transferred from the firefighter's hands to the firefighter's neck and waist. However, although this support method increases the stability of the fire hose to a certain extent, it still essentially requires the firefighters to use their hands to resolve the recoil, which causes the firefighters to easily become tired and unable to effectively resolve the recoil of the fire hose, seriously affecting the efficiency of firefighting operations.

[0004] This case was created to solve the above problems. Utility Model Content

[0023] The utility model is further described in detail below through the drawings and embodiments.

[0024] like Figure 1-6 As shown: a highly stable fire-fighting water gun, comprising a water pipe 2 and a gun head 1 connected to the water pipe 2, a raised ring 11 is sleeved on the gun head 1, and the protrusion of the raised ring 11 faces outward, a limiting ring 12 is provided on the outer side of the raised ring 11, and a groove matching the raised ring 11 is provided on the limiting ring 12, a connecting rod 3 is provided below the water pipe 2, an adjusting assembly 6 is provided on the connecting rod 3, and the adjusting assembly 6 is connected to the limiting ring 12, a supporting frame 5 is connected below the connecting rod 3, and a shoe cover 51 is provided at the bottom of the supporting frame 5 for fixing and cooperating with the limiting ring 12 and the connecting rod 3 to stabilize the fire-fighting water gun.

[0025] The cross section of the support frame 5 is triangular, and the shoe cover 51 is made of a hard material and is fixedly connected to the support frame 5 .

[0026] The adjustment assembly 6 includes an adjustment rod 61 with one end slidably connected to the connecting rod 3, a cross telescopic rod 62 with one end located at the end of the connecting rod 3, and a connecting plate 63 located at the end of the adjustment rod 61. The limit ring 12 is hinged to the upper end of the connecting plate 63, the end of the cross telescopic rod 62 is connected to the connecting plate 63, and the cross telescopic rod 62, the adjustment rod 61 and the connecting rod 3 form a triangular cross-section.

[0027] A plurality of fixing grooves 31 are arranged in an array on the connecting rod 3 , and the size of the fixing groove 31 matches the size of the end of the adjusting rod 61 , so as to be used for inserting and fixing the adjusting rod 61 .

[0028] A placement guard plate 7 is provided on the top of the connecting rod 3 . The placement guard plate 7 is arc-shaped, and the arc-shaped surface is matched with the surface of the water pipe 2 , and is used for placing the water pipe 2 .

[0029] The support frame 5 is provided with an arc-shaped fixed belt 4, and an insert block 41 is connected to one end of the fixed belt 4, and a notch is provided at the other end of the fixed belt 4, and the shape of the notch is adapted to the insert block 41 for tightening the fixed belt 4.

[0030] When in use, the firefighter puts his right foot into the shoe cover 51, which is made of wood or iron, and tightens the insert 41 on the fixed belt 4 to fix the fixed belt 4 on the firefighter's waist, so that the device moves with the firefighter as he moves.

[0031] When the spraying point is reached, the firefighter sets up the water pipe 2 on the placement guard plate 7 so that the placement guard plate 7 bears the gravity of the water pipe 2 and transmits it downward to the connecting rod 3 and the support frame 5, thereby relying on the ground to resist the gravity applied by the water pipe 2, preventing the firefighter from lifting the water pipe 2 for a long time and causing fatigue. At the same time, the gun head 1 is placed in the limiting ring 12. Since a raised ring 11 is fixedly provided on the gun head 1, which is mutually engaged with the limiting ring 12, the gun head 1 is fixed on the limiting ring 12, and the gun head 1 is opened to spray water to the area where fire needs to be extinguished. At this time, the recoil generated by the water spraying is first transmitted to the triangular area formed by the cross telescopic rod 62, the adjusting rod 61 and the connecting rod 3, and the stability of the triangle is used to resolve the recoil to a certain extent. At the same time, the firefighter himself steps on the shoe cover 51 and uses the firefighter's own gravity to maintain the stability of the entire device, so that the firefighter does not need to manually offset the recoil.

[0032] When it is necessary to adjust the angle of the spray water flow, the end of the adjusting rod 61 is pulled out from the fixing groove 31 of the connecting rod 3, so that the cross telescopic rod 62, the adjusting rod 61 and the connecting rod 3 form a triangle and are opened, and then slide to the upper fixing groove 31 position and press into the fixing groove 31, so that the adjusting rod 61 is fixed in the fixing groove 31 of the connecting rod 3, and a stable triangle is formed again between the cross telescopic rod 62, the adjusting rod 61 and the connecting rod 3, and by adjusting the inclination angle of the hinge block 32, the spraying angle of the sprinkler head 1 is changed, thereby improving the efficiency of the firefighting operation.

[0033] The above-mentioned embodiments are for inspiration. Through the above-mentioned description, relevant staff can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
