However, in this device, "a ring sleeve is provided on the back side of the back frame, and the water tank is inserted into the ring sleeve", and the water tank is simply inserted into the ring sleeve, and the placement stability is poor. When the firefighters are on a steep slope in the forest, or their bodies are tilted at a certain angle, the water tank is prone to movement, or even fall off from the ring sleeve, affecting the firefighting operation, which has disadvantages. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a backpack structure, which is convenient for carrying and moving fire-fighting equipment and is suitable for forest terrain environments. The water tank is firmly supported to prevent the water tank from moving or even falling off the mobile back frame when the firefighters are on a steep slope in the forest or their bodies are tilted at a certain angle. The water tank is easy to disassemble, assemble and replace while the firefighting operation is carried out, and the forest fire-fighting device can be easily assembled and operated with other equipment.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0007] The position control support plate of the utility model has a slide rod through hole, the slide rod through hole is adapted to the slide rod, the slide rod passes through the slide rod through hole, both ends of the slide rod are connected to a back frame, the outside of the back frame is provided with a placement ring, the placement ring is connected to the outside of the rubber sleeve, and the inside of the rubber sleeve is connected to the fire extinguisher barrel.

[0008] The fire extinguisher barrel of the utility model has a limiting circular plate, which fits the placement ring. The fire extinguisher barrel is connected to one end of a water hose, the other end of the water hose is connected to a delivery pump, the delivery pump is connected to a battery, the lower part of the battery is connected to a support plate, and the upper part of the support plate is connected to the delivery pump. Beneficial Effects

[0009] The shoulder strap of the utility model is provided with an adjustment buckle, and the length of the shoulder strap can be flexibly retracted or extended according to the actual height of the firefighter. The soft pad on the back increases the carrying comfort of the shoulder frame and reduces the working burden of the firefighter. The shoulder strap structure is easy to carry and move, and is suitable for forest terrain environments. The placement ring on the outside of the shoulder frame provides a hanging fulcrum for the fire extinguisher barrel, which improves the convenience of taking and placing the fire extinguisher barrel. The internal rubber sleeve increases the friction resistance between the placement ring and the contact surface of the fire extinguisher barrel, preventing the fire extinguisher barrel from falling when the firefighter moves.

[0010] The utility model discloses that water is filled into the water tank through the filling convex pipe, and after being carried to the forest fire extinguishing point through the back frame, it is extracted and transported into the fire extinguishing gun barrel through the water guiding hose, the delivery pump and the water delivery hose to extinguish the fire point. The storage battery is connected with the delivery pump through the electric wire to provide electric energy for the control drive of the delivery pump. The nut is fixedly connected with the filling convex pipe through the thread, and the disassembly and assembly are convenient. The water guiding hose can be quickly assembled with the replaced water tank, which saves the assembly time between the water tank and the equipment after the replacement. At the same time, the anti-detachment baffle is used to limit the position to prevent the water guiding hose from floating up and detaching from the water tank, thereby improving the structural stability.

[0011] The two sides of the threaded support rod of the utility model are respectively positioned and connected with the threaded support sleeves on both sides through positive and negative threads, so that when the threaded support rod is driven to rotate by turning the knob, the threaded support sleeves on both sides drive the clamping plates on both sides to perform synchronous linear displacement inward or outward at the same time through the position control support plate. When the clamping plate is displaced until its inner surface is in contact with the outer surface of the water tank and the locking block is embedded in the locking groove, the supporting positioning of the back frame on the water tank can be increased, and the carrying stability of the water tank can be strengthened, so as to avoid the water tank from moving or even falling off the back frame when the firefighter is on a steep slope in the forest or his body is tilted at a certain angle, thereby ensuring the normal progress of the firefighting operation. When the water in the water tank is exhausted and the water tank needs to be replaced, the clamping plate can be driven to move by turning the knob in the opposite direction, and the locking block is completely separated from the locking groove. At this time, the positioning fulcrum of the back frame on the water tank disappears, and the water tank can be quickly disassembled and replaced, and the operation is convenient.

[0012] The utility model adopts a backpack structure, which is convenient for carrying and moving fire-fighting equipment and is suitable for forest terrain environments. The water tank is firmly supported to prevent the water tank from moving or even falling off the backpack when the firefighters are on a steep slope in the forest or their bodies are tilted at a certain angle. While ensuring the normal progress of firefighting operations, the water tank is easy to disassemble, assemble and replace, and is convenient to assemble and operate with equipment.
