[0013] Figure 2 This is a structural schematic diagram of the connecting pipe part of a backpack-type fire extinguishing device proposed by the utility model;

[0014] Figure 3 This is a cross-sectional view of a three-dimensional view of the connecting pipe part of a backpack-type fire extinguishing device proposed by the utility model.

[0015] In the figure: 1. water tank; 2. shoulder strap; 3. first connecting pipe; 4. water gun; 5. second connecting pipe; 6. connecting ring; 7. spring; 8. pull rope; 9. winding reel; 10. worm gear; 11. worm; 12. sealing ring; 13. connecting pipe; 14. nozzle. DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Example 1: Reference Figure 1-3 A backpack fire extinguishing equipment comprises a water tank 1, the water tank 1 is connected with a shoulder strap 2, the shoulder strap 2 plays a role of carrying, the water tank 1 is connected with a connecting hose 13, the connecting hose 13 is connected with a water gun 4, the water gun 4 is connected with a first connecting pipe 3, a sealing ring 12 is abutted in the first connecting pipe 3, the sealing ring 12 plays a sealing role, a second connecting pipe 5 is fixedly connected to the sealing ring 12, the second connecting pipe 5 is connected with a nozzle 14, the first connecting pipe 3 and the second connecting pipe 5 are adjusted by an adjusting mechanism, and the position of the second connecting pipe 5 in the first connecting pipe 3 is adjusted to adjust the length of the connecting pipe part, so that when extinguishing a fire on a tree trunk, water can be sprayed on the tree trunk to extinguish the fire.

[0018] The adjusting mechanism includes a connecting ring 6, and the connecting ring 6 is fixedly connected to the first connecting tube 3 and the second connecting tube 5. A spring 7 is arranged between the two connecting rings 6. The connecting ring 6 located on the second connecting tube 5 is connected to a pull rope 8, and the pull rope 8 is pulled by a pulling mechanism. By loosening the pull rope 8, the second connecting tube 5 will be driven to move under the action of the restoring force of the spring 7, so as to adjust the position of the second connecting tube 5 in the first connecting tube 3. When it is necessary to increase the overall length of the connecting tube part, the second connecting tube 5 is pulled by the pulling mechanism to insert the second connecting tube 5 into the first connecting tube 3, thereby shortening the overall length of the connecting tube part.

[0019] The pulling mechanism includes a winding reel 9, which is rotatably connected to the water gun 4 through a bearing, and the winding reel 9 is connected to the pull rope 8. A worm wheel 10 is fixedly connected to the winding reel 9, and a worm 11 is rotatably connected to the water gun 4 through a bearing, and the worm 11 is meshed with the worm wheel 10. The worm 11 rotates, thereby driving the worm wheel 10 to rotate, so that the winding reel 9 rotates, thereby adjusting the length of the connecting pipe part. At the same time, due to the self-locking property between the worm 11 and the worm wheel 10, the winding reel 9 is prevented from rotating when in use, thereby ensuring the fixation of the position of the second connecting pipe 5.

[0020] When extinguishing a tree trunk fire, the worm 11 is rotated to drive the worm wheel 10 to rotate, so that the winding reel 9 is rotated and the pull rope 8 is unwound. Under the action of the restoring force of the spring 7, the position of the second connecting pipe 5 in the first connecting pipe 3 is adjusted to adjust the length of the connecting pipe part, the nozzle 14 is aimed at the fire, and the water gun 4 is pressed to spray water to extinguish the fire.

[0021] Example 2: Reference Figure 1-3 As another preferred embodiment of the utility model, on the basis of embodiment 1, the plastic material is prone to thermal deformation, and the water tank 1 is made of aluminum material to avoid this situation. At the same time, the weight is lighter than other metal materials.

[0022] The first connecting pipe 3, the second connecting pipe 5 and the spring 7 are all provided with an anti-rust layer, which is formed by the drying of the paint to prevent rust.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
