Description
Technical Field
[0001] This invention relates to the field of fire-fighting auxiliary tools, and more particularly to a foldable mobile fire hose rack. Background Technology
[0002] As the core equipment for fire fighting, the stable placement and flexible adaptation of fire hoses directly affect fire fighting efficiency and operational safety. In existing technologies, fire hose racks are mostly fixed structures, which are bulky and inconvenient for folding, storage, and transportation. During routine storage or cross-regional rescue operations, fixed racks occupy a lot of space, making them unsuitable for the limited storage space of fire trucks and the need for rapid deployment in various scenarios. Furthermore, their rigid structure makes them prone to damage during transport, significantly reducing the portability and lifespan of the equipment. Meanwhile, the angle adjustment function of existing fire hose racks has significant limitations. Most racks can only provide support at a single fixed angle, and cannot flexibly adjust the spray angle of the fire hose according to the actual location, height, and direction of fire spread. Although some have simple adjustment structures, the adjustment operation is cumbersome, and there is a lack of a reliable locking mechanism after adjustment. Therefore, we propose a foldable mobile fire hose rack. Summary of the Invention

[0014] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0015] Example like Figure 1 and Figure 2 As shown, a foldable fire hose reel mobile storage rack is provided, including a storage frame 1 and a storage frame 2 on the right side of the storage frame 1. Two bearing seats 3 are fixedly connected to the front surface of the placement frame 1. The two bearing seats 3 are connected to a screw 4 through a rotating shaft. A screw block 5 is threaded on the outer wall of the screw 4. A connecting rod 6 is rotatably connected to the front surface of the screw block 5 through a rotating shaft. The right side of the rear surface of the connecting rod 6 is rotatably connected to the lower part of the front surface of the placement frame 2 through a rotating shaft. Two fixing blocks 7 are fixedly connected to the rear surface of the placement frame 1. A guide rod 8 is fixedly connected between the two fixing blocks 7. A guide block 9 is slidably connected to the outer wall of the guide rod 8. A connecting rod 10 is rotatably connected to the rear surface of the guide block 9 through a pivot. The right side of the front surface of the connecting rod 10 is rotatably connected to the lower part of the rear surface of the placement frame 2 through a pivot. A knob 14 is fixedly connected to the top of screw 4; This part is used to realize the folding and unfolding operation of the placement rack. When in use, turn the knob 14 to drive the screw 4 to rotate around the shaft between the two bearings 3. When the screw 4 rotates, it drives the screw block 5 connected to the outer wall thread to move up and down along the axis of the screw 4. When the screw block 5 moves, it drives the connecting rod 6 to rotate through the shaft. At the same time, the connecting rod 10 on the rear surface of the placement frame 2 rotates synchronously with the movement of the placement frame 2. The guide block 9 slides along the guide rod 8 to guide and limit. When the screw block 5 moves upward, the connecting rod 16 and the connecting rod 10 push the placement frame 2 closer to the placement frame 1, realizing the folding of the placement rack. When the screw block 5 moves downward, the connecting rod 6 and the connecting rod 10 pull the placement frame 2 away from the placement frame 1, realizing the unfolding of the placement rack. After folding, it is easy to store and transport. After unfolding, it can stably support the fire hose.
[0016] like Figure 1 As shown, two universal wheels 11 are fixedly connected to the lower surface of both the first placement frame 1 and the second placement frame 2; The casters 11 are used to enable flexible movement of the placement rack. When the placement rack is unfolded or folded, the staff can push the placement frame 1 or the placement frame 2, and the entire placement rack will be moved by the rolling of the four casters 11. This makes it easy to transfer the placement rack to the designated location at the fire scene, adapting to the needs of rapid deployment in multiple scenarios. It eliminates the need for manual handling, reduces the labor intensity of the staff, and avoids damage to the placement rack during the handling process.
[0017] like Figure 3 As shown, a rear seat abutment block 12 is rotatably connected to the inner side of the placement frame 1 via a rotating shaft, and a U-shaped through-hole 13 is provided on the left side of the rear seat abutment block 12. The rear seat abutment block 12 is used to support the rear seat of the fire nozzle, and the U-shaped pipe opening 13 is used to pass through the fire hose. In use, the rear seat of the fire nozzle is abutted against the rear seat abutment block 12 on the inner side of the placement frame 1, and the fire hose is passed through the U-shaped pipe opening 13 to connect with the fire nozzle. This can limit the fire hose and prevent it from getting tangled or falling off. At the same time, the rear seat abutment block 12 can rotate around the pivot, and in conjunction with the subsequent angle adjustment structure, the spray angle of the fire nozzle can be flexibly adjusted.
[0018] like Figure 4 and Figure 5 As shown, the front surface of the second placement frame 2 has a vertical groove 15. The inside of the vertical groove 15 is rotatably connected to the screw 16 via a rotating shaft. The outer side wall of the screw 16 is threaded with a screw block 17. The rear surface of the second placement frame 2 has a vertical groove 18. The inside of the vertical groove 18 is fixedly connected to the guide rod 19. The outer side wall of the guide rod 19 is slidably connected to the guide block 20. The opposite sides of the screw block 17 and the guide block 20 are rotatably mounted with a clamping sleeve 21 via a rotating shaft. The top end of screw 16 extends through to the top of placement frame 2 and is fixedly connected to knob 22; The top of the clamping sleeve 21 is threaded with a fastening bolt 23, and the bottom end of the fastening bolt 23 extends through to the inside of the clamping sleeve 21. This part is used to clamp and fix the fire hose nozzle body and adjust its height and angle. In use, first place the fire hose nozzle body into the inside of the clamping sleeve 21, rotate the fastening bolt 23 so that the bottom end of the fastening bolt 23 abuts against the nozzle body to fix and lock the fire hose nozzle; rotate the knob 22 to drive the screw 16 to rotate around the shaft inside the vertical groove 15. The rotation of the screw 16 drives the screw block 17 to slide up and down along the vertical groove 15. At the same time, the guide block 20 slides synchronously along the guide rod 19 inside the vertical groove 18 to guide. When the screw block 17 and the guide block 20 move up and down, the clamping sleeve 21 is driven to rise and fall synchronously through the shaft to adjust the angle of the fire hose nozzle, ensuring that the angle is stable during spraying. It can be flexibly adjusted according to the location, height and direction of fire spread, improving fire extinguishing efficiency.
[0019] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
