Description

Technical Field

[0001] The invention relates to the technical field of fire boots, in particular to a fire boot for fire fighting and extinguishing. Background Art

[0002] Fire boots are a kind of functional protective boots designed for firefighters. They are mainly used to protect firefighters from high temperature, flames, sharp objects and water stains during firefighting and rescue operations. They are usually made of flame-retardant, waterproof, non-slip and puncture-resistant materials. The soles are resistant to high temperatures and non-slip, and the boots can cover the calves for additional protection. Some high-end fire boots also integrate thermal insulation, anti-static functions and smart sensors to further enhance safety and practicality. Fire boots are an important part of firefighters' personal protective equipment, ensuring that they can complete their tasks safely and efficiently in extreme environments.

[0003] Before firefighters go out to put out fires, they often wear firefighting equipment, among which fire boots are indispensable. However, during the use of current fire boots, due to the large opening at the upper end of the fire boot shaft, the legs of firefighters are too open when using the fire boots. When walking or running, the fire boots cannot fit tightly to the legs, which will cause discomfort, thus affecting the firefighters' firefighting and rescue work. Summary of the invention

[0004] The object of the present invention is to provide a fire boot for fire fighting to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a firefighting boot for firefighting, comprising a firefighting boot body and a sole, and also comprising;

[0006] The airbag 1 is embedded in the inner side of the fire boot body, a shell is fixed on the right side of the fire boot body, a screw is rotatably connected to the top of the inner cavity of the shell, a fixing sleeve is threadedly connected to the surface of the screw, a pressure plate is arranged at the other end of the fixing sleeve, airbag 2 is fixed between the bottom of the pressure plate and the inner wall of the shell, a connecting pipe is connected to the left side of the airbag 2, and the other end of the connecting pipe passes through the fire boot body and is connected to the airbag 1;

[0007] A force-applying structure is arranged inside the shell and used to drive the screw to rotate, and a water outlet hole is opened on both the front and rear sides of the bottom of the fire boot body;

[0008] A limit plate movably connected to the inside of the right end of the sole, two water outlet holes are opened on both sides of the limit plate, a spring is fixed on both sides between the other side of the limit plate and the inner wall of the sole, and drainage holes are opened on both sides of the bottom of the sole;

[0009] A movable plate is movably connected to both sides of the sole, and a plurality of anti-slip protrusions are fixed to the bottom of the movable plate. A plurality of springs are fixed between the top of the movable plate and the inside of the sole. Limiting structures for limiting the movable plate are arranged at the front and rear of both sides of the sole.

[0033] The force-applying structure 10 includes a torsion plate 101, a first bevel gear 102 and a second bevel gear 103. The torsion plate 101 is arranged on the right side of the housing 4. The left side of the torsion plate 101 is fixed to one side of the first bevel gear 102 through a rotating rod. The second bevel gear 103 is fixed to the surface of the screw 5. One side of the first bevel gear 102 is meshed with one side of the second bevel gear 103. In this way, when the screw 5 is driven to rotate, the torsion plate 101 can be rotated, and the first bevel gear 102 can be driven to rotate through the rotating rod, and the second bevel gear 103 and the screw 5 can be driven to rotate at the same time.

[0034] The limiting structure 20 includes a concave rod 201, a limiting plate 202, a spring three 203 and a limiting hole 204. The concave rod 201 is movably connected to the front and rear of both sides of the sole 2. The limiting plate 202 is fixed to the surface of one end of the concave rod 201. The spring three 203 is sleeved on the surface of the concave rod 201. The two ends of the spring three 203 are respectively fixed to the limiting plate 202 and the inner wall of the sole 2. The limiting holes 204 are arranged in the front and rear of both sides of the movable plate 18. In this way, the elastic force of the spring three 203 itself can drive the limiting plate 202 and the concave rod 201 to move backward, so that one end of the concave rod 201 enters the interior of the limiting hole 204, thereby limiting the movable plate 18.

[0037] A fixing rod 16 is fixedly connected to both sides of the inner wall of the sole 2, and the other end of the fixing rod 16 is movably connected to the inside of the limit plate 14. A spring 17 is sleeved on the surface of the fixing rod 16, so that the limit plate 14 can be auxiliary supported and the stability of the limit plate 14 can be maintained when it moves.

[0038] A restraining strap 24 is fixed to the top of the outer surface of the fire boot body 1, a Velcro surface 25 is arranged on the outer side of one end of the restraining strap 24, a Velcro hook surface 26 is arranged on one side of one end of the restraining strap 24, and the Velcro surface 25 and the Velcro hook surface 26 are bonded to each other, so that after the firefighter wears the fire boot body 1, the restraining strap 24 can be used to tighten the fire boot body 1.

[0039] Handles 27 are provided on both sides of the top of the fire boot body 1, so that the fire boot body 1 is convenient to carry and take.

[0040] A groove 29 is formed on the right side of the housing 4 , and the torsion plate 101 is located inside the groove 29 , so that the torsion plate 101 does not protrude from the outer surface of the housing 4 .

[0041] Reflective strips 28 are provided on both the front and rear sides of the fire boot body 1, so that reflective reminders can be provided under the illumination of light.

[0042] Working principle: After the firefighter steps into the fire boot body 1 and puts it on, the force structure 10 can drive the screw 5 to rotate, and drive the fixing sleeve 6 and the pressure plate 7 to move downward, thereby squeezing the airbag 2 8, so that the gas inside the airbag 2 8 enters the airbag 1 3 through the connecting pipe 9. At this time, the airbag 1 3 will expand and contact the firefighter's legs. This not only improves the comfort of the firefighter after wearing, but also avoids the gap between the fire boot body 1 and the firefighter's legs being too large to affect subsequent use. If the ground for extinguishing the fire is relatively smooth, the firefighter can lift one leg at this time. , and pull the concave rod 201 outward, then drive the limit plate 202 to squeeze the spring three 203. At this time, the spring two 21 can drive the movable plate 18 and the anti-skid protrusion 19 to move downward through its own elastic force until the anti-skid protrusion 19 protrudes, and then release the concave rod 201, and through the elastic force of the spring three 203 itself, it can drive one end of the concave rod 201 to enter the inside of the limiting hole 204, thereby limiting the movable plate 18. This can increase the friction between the sole 2 and the ground to prevent slipping. During the fire fighting, when the firefighters are resting on the spot, there will be water in the fire boots. Then the foot can be lifted up so that the bottom end of the sole 2 contacts the ground, and the limiting plate 14 is pressed. The pressed limiting plate 14 will enter the inner side of the sole 2. At this time, the water outlet 2 15 will be connected with the water outlet 1 13 and the drainage hole 22. Finally, the water source inside the fire boot body 1 will be discharged through the water outlet 13, the limiting plate 14 and the drainage hole 22, thereby reducing the trouble of cleaning the slippers back and forth.
