Description

Technical Field

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

[0002] Fire hoses are water-spraying tools for extinguishing fires. Fire hoses can be divided into direct current hoses, spray hoses, and multi-purpose hoses according to the jet form and characteristics. Direct current hoses are commonly used. The water jet from a direct current hose is columnar and has a strong impact, but the water jet cannot change direction during use. When a fire occurs, there are many places that firefighters cannot enter directly. At this time, firefighters shoot water into the room from outside the door or window. However, the existing fire hoses cannot directly reach the fire beams, windows, and other fire sites in the house. This will result in jet blind spots and the maximum effect of the fire hose cannot be achieved.

[0003] This case was created to solve the above problems. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a novel corner fire-fighting water gun, which solves the problems raised in the above-mentioned background technology.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a new type of corner fire-fighting water gun, including a gun head, a gun barrel and a valve connected in sequence, a handle connected to the bottom of the valve, and a relatively rotatable handle installed on the upper side of the valve, wherein the gun head is connected to the gun barrel through a connecting pipe fitting and is detachably connected through a pipe sleeve, and the gun head is adjusted and the water outlet angle is changed through the connecting pipe fitting.

[0008] Preferably, the connecting pipe comprises a folded pipe, wherein the folded pipe forms an angle after being connected to the gun barrel, and the folded pipe is fastened to the gun barrel through a pipe sleeve to form a single water outlet angle of the gun head.

[0009] Preferably, the connecting pipe comprises a hose, and a steel wire rope is movably connected between the gun head and the handle, and the real-time change of the spraying angle of the gun head is achieved by rotating the handle with force in coordination with the gravity of the gun head.

[0010] Preferably, the length of the wire rope is such that when the gun barrel is rotated to the desired uppermost position, the handle rotates backwards until it almost touches the valve, and when it is rotated to the desired lowermost position, the handle rotates forwards until it almost touches the valve, and is in a taut state when in use.

[0011] Preferably, a winding seat is provided at the valve, wherein the wire rope is provided with surplus, and the excess wire rope is wound onto the winding seat, so that the exposed part of the wire rope is in a taut state.

[0012] Preferably, the hose is made of a deformable metal material.

[0013] (III) Beneficial effects

[0014] After adopting the above technical scheme, the utility model has the following advantages compared with the prior art: the utility model provides a new type of corner fire water gun, which can be controlled at a relatively long distance through the cooperation between the hose, the wire rope and the handle, and the spray angle can be adjusted in real time according to the fire source.

[0018] The utility model is further described in detail below through the drawings and embodiments.

[0019] like Figure 1 As shown: a new type of corner fire-fighting water gun, including a gun head 4, a gun barrel 3 and a valve 1 which are connected in sequence, the valve 1 is connected to an external water outlet pipe, the bottom of the valve 1 is connected to a handle 2, and a relatively rotatable handle 6 is installed on the upper side, wherein the length of the gun barrel 3 can be set longer, and then the fire-fighting water gun can be used by using both hands to exert force in conjunction with the handle 2 and the handle 6 to control the spraying of the fire-fighting water gun.

[0020] The gun head 4 is connected to the gun barrel 3 through a folding tube 9, and the connection between the two is connected through a pipe sleeve 5, so that the gun head 4 and the gun barrel 3 have a certain fixed angle under normal conditions, which is conducive to the switching of the upper and lower angles (in the horizontal state, only the entire valve 1 and the gun barrel 3 need to be held horizontally). The pipe sleeve 5 can be movably connected to the gun barrel 3 (bolt fastening, clamping, etc.), thereby realizing flexible disassembly and installation.

[0021] When the folded tube 9 is connected, it can only be used at a fixed angle, and has poor controllability and a small scope of application. Therefore, further improvements are made to the folded tube 9.

[0022] As attached Figure 2 As shown, the middle part of the folded tube 9 is replaced by a hose 7 instead of a rigid pipe, so that the spray direction at the gun head 4 can be changed in real time according to the external force. The downward force is provided by the gravity of the gun head 4 itself, and a steel wire rope 8 is connected between the gun head 4 and the handle 6. By applying force to rotate the handle 6 and cooperating with the gravity of the gun head 4, the spray angle of the gun head 4 is changed. At the same time, combined with the deflection of the entire valve 1, the full-range angle switching of the gun head 4 can be implemented.

[0023] The weight of the gun head 4 should not be too heavy, otherwise it will easily deflect sideways and be difficult to control.

[0024] It should be noted that the length of the steel wire rope 8 needs to be controlled so that it is basically in a tight state when in use. Figure 2 In this embodiment, when the gun barrel 3 is rotated to the desired uppermost position, the handle 6 is rotated backward until it almost touches the valve 1 , and when it is rotated to the desired lowermost position, the handle 6 is rotated forward until it almost touches the valve 1 .

[0025] A winding seat may also be provided at the valve 1, and the wire rope 8 may be provided with a surplus so that the exposed portion of the wire rope 8 is also in a taut state.

[0026] The hose 7 is preferably made of a metal deformable material (such as a conventional memory alloy material) to avoid damage due to high temperature of a fire source.

[0027] Fire hoses can be controlled at a relatively long distance, and the spray angle can be adjusted in real time according to the fire source. The application of controlled spray guns is more flexible, especially when there are multiple fires in a building that are located in the blind spots of the jets. There is no need to change the spray angle before adjusting the nozzle.

[0028] The corner fire-fighting water gun of this embodiment has a wide range of applications, especially when there are many fires in buildings that are located in the blind spots of the jet, and conventional direct current water guns cannot be used. Secondly, when used for electric vehicle fire extinguishing, with the help of the flexible adjustment of the length of the barrel 3 and the angle of the nozzle, it can penetrate into the battery position at the bottom of the electric vehicle to directly extinguish the fire.

[0029] 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.
