Description

Technical Field

[0001] This utility model relates to the field of fire hose technology, and in particular to a fire hose with an adjustable spray angle. Background Technology

[0002] Fire hoses are devices used by firefighters to spray water or other extinguishing agents (such as foam or dry powder) during fire fighting and rescue operations. By connecting to fire hoses, they convert the high-pressure water flow delivered by fire pumps into jets with specific shapes (direct flow, spray, spray, etc.) to achieve functions such as fire extinguishing, cooling, dilution, and isolation.

[0003] Existing technologies, such as the utility model patent with publication number CN207913069U, disclose a fire hose nozzle, including an outer wall, a spray pipe, and a hose. The spray pipe is threaded to the outer wall, and the front part of the hose is inserted into the rear part of the outer wall and fixed by a stainless steel ring. The stainless steel ring is formed by rolling a stainless steel strip with a length greater than the inner diameter of the outer wall, creating an opening. One end of the opening has a row of first positioning teeth, and the other end has second positioning teeth that engage with the first positioning teeth. A flow guide base is located in front of the positioning ring on the inner wall, and the edge of the flow guide base has an annular sealing protrusion. A sealing ring is located at the rear end of the spray pipe. In this utility model, the hose is fixed to the outer wall by an adjustable stainless steel ring. As the hose is used, the diameter of the stainless steel ring increases, thus ensuring that the hose is tightly fastened to the inner wall of the outer wall, preventing loosening or detachment. The water shut-off structure is relatively simple.

[0004] Based on the above, the following problems were found: When using fire hoses to extinguish fires, it is difficult to adjust the spray angle, which leads to inaccurate coverage of the fire source and inefficient use of water, reducing fire extinguishing safety and thus reducing the fire extinguishing efficiency of traditional fire hoses. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in adjusting the spray angle when using fire hoses to extinguish fires, which leads to inaccurate coverage of the fire source and inefficient use of water, thus reducing fire extinguishing safety and efficiency. Therefore, this invention proposes a fire hose with an adjustable spray angle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable spray angle fire hose, comprising a fire hose, one end of which is fitted with a nozzle, an adjustment device on the lower surface of the fire hose, the adjustment device comprising a rotating base, the upper surface of which is fixedly connected to the fire hose, fixed bases rotatably connected to both sides of the rotating base, a plurality of limiting holes being provided inside the fixed base, a fixing hole being provided inside the rotating base, pins being fitted into the fixing hole and the limiting hole, a turntable being fixedly connected to the lower surface of the fixed base, a rotating shaft being fixedly connected to the lower surface of the turntable, and a rotating platform being rotatably connected to the lower surface of the rotating shaft.

[0007] The effect achieved by the above components is to increase the spray range of the water gun by adjusting the water gun at multiple angles.

[0008] Preferably, the lower surface of the rotary table is rotatably connected to three legs, and a baffle is provided at the connection between the rotary table and the legs to limit the rotation angle of the legs.

[0009] The aforementioned components achieve the following effects: they enable the water gun to adapt to uneven ground, increase the stability of the water gun, and reduce the recoil force when the water gun is spraying.

[0010] Preferably, an anti-slip pad is fixedly connected to the lower surface of the support foot, and the surface of the anti-slip pad has irregular protrusions.

[0011] The effect achieved by the above components is to increase friction and enhance the stability of the support legs.

[0012] Preferably, the water gun has a handle fixedly connected to its arc surface, and the handle has a U-shaped cross-section.

[0013] The effect achieved by the above components is to allow for quick adjustment of the water gun angle using the handle.

[0014] Preferably, the water gun has a foam mixing device on its arc surface. The foam mixing device includes a foam liquid tank. The lower end of the foam liquid tank is fixedly connected to the water gun. A rotary switch is rotatably connected inside the foam liquid tank. A lid is rotatably connected to the upper surface of the foam liquid tank.

[0015] The effect achieved by the above components is to spray foam using foam liquid in the foam liquid tank in conjunction with a specific nozzle.

[0016] Preferably, one end of the water gun is fixedly connected to a threaded connector, and a control valve is rotatably connected inside the threaded connector.

[0017] The effects achieved by the above components are: quick installation of water pipes using threaded connectors, control of the water output of the water gun, and spraying of foam in conjunction with the foam liquid tank.

[0018] Preferably, a filter screen is fixedly connected inside the threaded joint, and the filter screen is made of stainless steel.

[0019] The effects achieved by the above components are: to filter impurities from the water outlet, prevent water gun clogging, and increase the service life of the water gun.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, when the water gun spray requires adjustment, the support leg rotatably connected to the rotating platform is rotated to its maximum angle and supported on the ground. Then, the pin inserted into the limiting hole and fixing hole to fix the rotating seat on the fixed seat is pulled out. The handle is pulled to rotate the angle of the water gun. After adjusting the water gun to a suitable angle, the pin is inserted along one of the limiting holes and fixing holes to fix the rotating seat on the fixed seat. Then, the water gun is connected to the water pipe, and the turntable is rotated. The rotation of the turntable drives the rotating shaft fixed on the lower surface of the turntable to rotate on the rotating platform to adjust the water gun's water outlet angle. At this time, the support leg can alleviate the recoil caused by the water gun's water outlet, reducing the pressure on the user. After use, the water pipe is removed, the support leg is retracted, and the angle of the water gun is adjusted back to its original position to reduce storage space.

[0022] In this invention, when a foam mixing device is needed to extinguish oil fires, the lid of the foam liquid tank is turned open, foam liquid is poured into the tank, and the lid is closed again. A water pipe is connected through the threaded connector at one end of the water gun. The filter screen in the threaded connector can filter impurities from the water outlet to prevent the water gun from clogging. The foam nozzle is then attached to the other end of the water gun, and the control valve and rotary switch are turned on to spray foam. When the water spray mode needs to be switched, the rotary switch can be turned off. The water flow can be controlled by rotating the control valve. After use, the rotary switch and control valve are turned off, and the original nozzle is then attached to one end of the water gun. Attached Figure Description

[0029] The specific settings and functions of the regulating device 3 and the foam mixing device 4 will be explained in detail below.

[0030] Reference Figure 2 and Figure 3 As shown in this embodiment: the adjusting device 3 includes a rotating base 301, the upper surface of which is fixedly connected to the water gun 1. Fixed bases 302 are rotatably connected to both sides of the rotating base 301. Several limiting holes 303 are provided inside the fixed bases 302. Fixed holes are provided inside the rotating base 301. Pins 304 are engaged with the fixed holes and limiting holes 303. A turntable 305 is fixedly connected to the lower surface of the fixed base 302. A rotating shaft 306 is fixedly connected to the lower surface of the turntable 305. A rotating platform 307 is rotatably connected to the lower surface of the rotating shaft 306. The effect achieved by these components is to increase the spray range of the water gun 1 by adjusting it at multiple angles. Three support legs 308 are rotatably connected to the lower surface of the rotating platform 307. A baffle is provided at the connection between the rotating platform 307 and the support legs 308 to limit the rotation angle of the support legs 308. The effect achieved by these components is to allow the water gun 1 to adapt to uneven ground, increase the stability of the water gun 1, and reduce the recoil force when the water gun 1 sprays. An anti-slip pad 309 is fixedly connected to the lower surface of the support leg 308. The surface of the anti-slip pad 309 has irregular protrusions. The effect of the above components is to increase friction and enhance the stability of the support leg 308. A handle 310 is fixedly connected to the arc surface of the water gun 1. The handle 310 has a "U" shaped cross-section. The effect of the above components is to allow for quick adjustment of the angle of the water gun 1 using the handle 310.

[0031] Reference Figure 4As shown in this embodiment: the foam mixing device 4 includes a foam liquid tank 41, the lower end of which is fixedly connected to the water gun 1. A rotary switch 43 is rotatably connected inside the foam liquid tank 41, and a tank cover 42 is rotatably connected to the upper surface of the foam liquid tank 41. The effect of the above components is to use the foam liquid in the foam liquid tank 41 to spray foam with a specific nozzle 2. One end of the water gun 1 is fixedly connected to a threaded connector 44, and a control valve 45 is rotatably connected inside the threaded connector 44. The effect of the above components is to use the threaded connector 44 to quickly install the water pipe, control the water output of the water gun 1, and coordinate with the foam liquid tank 41 to spray foam. A filter screen 46 is fixedly connected inside the threaded connector 44. The filter screen 46 is made of stainless steel. The effect of the above components is to filter impurities brought by the water pipe outlet, prevent the water gun 1 from clogging, and increase the service life of the water gun 1.

[0032] Working principle: When the water gun 1 needs to spray and the adjustment device 3 is required, rotate the support leg 308, which is rotatably connected to the rotating table 307, to the maximum angle to support it on the ground. Then, pull out the pin 304 that is inserted into the limiting hole 303 and the fixing hole to fix the rotating seat 301 on the fixing seat 302. Pull the handle 310 to rotate the angle of the water gun 1. After adjusting the water gun 1 to a suitable angle, insert the pin 304 along one of the limiting holes 303 and the fixing hole to fix the rotating seat 301 on the fixing seat 302. Then, connect the water gun 1 to the water pipe and rotate the turntable 305. The rotation of the turntable 305 drives the rotating shaft 306, which is fixed on the lower surface of the turntable 305, to rotate on the rotating table 307 to adjust the water outlet angle of the water gun 1. At this time, the support leg 308 can relieve the recoil caused by the water gun 1 spraying water and reduce the pressure on the user. After use, remove the water pipe, retract the support leg 308, and adjust the angle of the water gun 1 back to its original position to reduce storage space.

[0033] In this utility model, when it is necessary to use the foam mixing device 4 to extinguish oil fires, rotate and open the cover 42 on the foam liquid tank 41, pour foam liquid into the foam liquid tank 41, and then close the cover 42. Connect the water pipe through the threaded connector 44 at one end of the water gun 1. At this time, the filter screen 46 in the threaded connector 44 can filter impurities brought by the water pipe outlet to prevent the water gun 1 from being blocked. Then, snap the foam nozzle onto the other end of the water gun 1, open the control valve 45 and the rotary switch 43 to spray foam. When it is necessary to switch the water spray state, simply close the rotary switch 43. When it is necessary to control the water flow, it can be controlled by rotating the control valve 45. After use, close the rotary switch 43 and the control valve 45, and then snap the original nozzle 2 onto one end of the water gun 1.
