Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and more specifically, to a handheld rotary fire hose reel. Background Technology

[0002] Fire hoses are indispensable equipment in firefighting operations. They are flexible tubes used to transport water or other liquid extinguishing agents and are widely used in fire fighting, disaster relief, and other scenarios. At the fire scene, fire hoses can quickly deliver water from fire trucks, fire hydrants, and other water sources to firefighting equipment or firefighters, providing a stable water supply for firefighting. Their performance and condition directly affect the efficiency and effectiveness of fire rescue. Fire hoses must be rolled up after use because randomly stacked fire hoses not only take up a lot of space but also easily lead to tangling and knotting, causing damage to the internal structure and shortening their service life. At the same time, messy fire hoses are difficult to deploy quickly in emergency rescues, which can seriously delay rescue opportunities. Properly rolled fire hoses are easy to store, manage, and quickly retrieve, ensuring they can play a role in critical moments.

[0003] A search revealed that Chinese patent application number CN202021567891.6 discloses a manual fire hose reel, comprising a base, a support rod fixedly connected to the top of the base, a fixed cylinder fixedly connected to the top of the support rod, a rotating shaft rotatably connected to the middle of the fixed cylinder via a bearing, a handle fixedly connected to one end of the rotating shaft, a limiting disc fixedly connected to the other end of the rotating shaft, a second fixed rod fixedly connected to the side of the limiting disc away from the fixed cylinder, and two second fixed rods, with a sleeve sleeved on the outer side of the second fixed rod;

[0004] Although the aforementioned patent describes a manual fire hose reel that, by setting up a sleeve, a handle, and a second fixing rod, allows the sleeve to be detached from the second fixing rod by pulling the handle, thus facilitating the removal of the wound fire hose and solving the problem of inconvenience in removing fire hoses, it still has the following shortcomings in use: 1. After the hose is wound up, the disassembly and installation process is cumbersome and requires a lot of time and effort, which cannot meet the needs of fire rescue where every second counts; 2. During the winding process, it is also difficult to adapt to different specifications of hoses, which can easily lead to the hose becoming loose or shifting, resulting in poor winding quality.

[0005] Therefore, there is an urgent need for a handheld rotary fire hose reel to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a handheld rotary fire hose reel to solve the problems mentioned in the background art.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] like Figure 1-6 As shown, this embodiment proposes a handheld rotary fire hose reel, including a fixed plate 1. A rotating rod 10 is rotatably connected to the outer wall of the fixed plate 1. A ratchet 9 is fixedly connected to the outer wall of the rotating rod 10. Symmetrically distributed linkage rods 13 are fixedly connected to the outer wall of the ratchet 9. A rotating plate 11 is fixedly connected to the outer wall of the rotating rod 10. A handle 12 is rotatably connected to the outer wall of the rotating plate 11. The operator holds the handle 12 on the rotating plate 11 and rotates the rotating rod 10. The rotating rod 10 drives the ratchet 9 to rotate, and the linkage rods 13 connected to the ratchet 9 rotate accordingly, thereby driving the rotating sleeve 19 to rotate, realizing the reel winding. A ratchet mechanism composed of a mounting plate 26, a strong spring 7, and a pawl 8 prevents the ratchet 9 from accidentally reversing. It also includes:

[0029] The quick unloading assembly includes an extension frame 6 fixedly connected to the outer wall of the fixed plate 1. A slider 15 is slidably connected to the outer wall of the extension frame 6. A strong tension spring 14 is fixedly connected to the outer wall of the slider 15, and the end of the strong tension spring 14 away from the slider 15 is fixedly connected to the extension frame 6. A connecting frame 16 is fixedly connected to the outer wall of the slider 15. A positioning frame 17 is rotatably connected to the outer wall of the connecting frame 16. A turntable 18 is rotatably connected to the outer wall of the positioning frame 17. After winding is completed, the slider 15 is pulled, and the slider 15 compresses the strong tension spring 14. The positioning frame 17 moves through the connecting frame 16, and the positioning frame 17 moves the turntable 18 and the rotating sleeve 19, so that the linkage rod 13 is disengaged from the rotating sleeve 19, and the wound fire hose can be quickly removed.

[0030] An adjustable limit component is located on the outer wall of the linkage rod 13.

[0031] like Figure 6As shown, in a preferred embodiment, based on the above method, the adjustable limiting component further includes a sleeve 25 slidably connected to the outer wall of the linkage rod 13. A rotating sleeve 19 is fixedly connected to the outer wall of the sleeve 25, and the rotating sleeve 19 is fixedly connected to the turntable 18. A symmetrically distributed screw 21 is rotatably connected to the inner wall of the rotating sleeve 19. A driven bevel gear 22 is fixedly connected to the outer wall of the screw 21. A knob 20 is rotatably connected to the outer wall of the rotating sleeve 19. A driving bevel gear 23 is fixedly connected to the outer wall of the knob 20, and the outer wall of the driving bevel gear 23 is fixedly connected to the outer wall of the knob 20. The screw 21 is threadedly connected to the outer wall of the driven bevel gear 22 and the outer wall of the screw 21 is threadedly connected to the limit bracket 24. The limit bracket 24 is slidably connected to the rotating sleeve 19. According to the width of the fire hose, the knob 20 is rotated, which drives the drive bevel gear 23 to rotate. The driven bevel gear 22, which meshes with the drive bevel gear 23, drives the screw 21 to rotate. The rotation of the screw 21 causes the threaded limit bracket 24 to slide on the rotating sleeve 19. The spacing of the limit bracket 24 is adjusted to achieve stable limiting of fire hoses of different widths and ensure that they will not deviate during the winding process.

[0032] like Figure 1 As shown, in a preferred embodiment, based on the above method, the outer wall of the fixed plate 1 is further provided with symmetrically distributed auxiliary rods 4, and the outer wall of the auxiliary rods 4 is rotatably connected with an anti-detachment frame 5. The water hose is initially positioned by using the symmetrically distributed auxiliary rods 4 and the rotatably connected anti-detachment frame 5 on the outer wall of the fixed plate 1.

[0033] like Figure 1 As shown, in a preferred embodiment, based on the above method, a mounting plate 26 is fixedly connected to the outer wall of the fixed disk 1, a strong spring 7 is fixedly connected to the outer wall of the mounting plate 26, a pawl 8 is fixedly connected to the end of the strong spring 7 away from the mounting plate 26, and the pawl 8 is rotatably connected to the fixed disk 1, and the strong spring 7 always pushes the pawl 8 to fit against the ratchet 9.

[0034] like Figure 1 As shown, in a preferred embodiment, based on the above method, the outer wall of the fixed disk 1 is further provided with symmetrically distributed support frames 2, and the end of the support frame 2 away from the fixed disk 1 is fixedly connected with a support plate 3. The equipment is supported and positioned by the support frame 2 and the support plate 3.

[0035] Specifically, when using this handheld rotary fire hose reel: The auxiliary rods symmetrically distributed on the outer wall of the fixed plate 1 and the rotatably connected anti-detachment bracket 5 are used to initially position the fire hose. The anti-detachment bracket 5 is located on the upper side of the fire hose to ensure stable starting of the reeling. One end of the fire hose is inserted crosswise onto the sleeve 25. Simultaneously, the ratchet mechanism, consisting of the mounting plate 26, a strong spring 7, and a pawl 8, prevents the ratchet 9 from accidentally reversing. The operator holds the handle 12 on the rotating plate 11 and rotates the rotating rod 10. The rotating rod 10 drives the ratchet 9 to rotate, and the linkage rod 13 connected to the ratchet 9 rotates accordingly, thereby driving the rotating sleeve 19 to rotate, achieving the reeling of the fire hose. According to the fire... To adjust the width of the fire hose, rotate knob 20. Knob 20 drives drive bevel gear 23 to rotate, and driven bevel gear 22, which meshes with drive bevel gear 23, drives screw 21 to rotate. The rotation of screw 21 causes threaded limit frame 24 to slide on rotating sleeve 19. Adjusting the spacing of limit frame 24 achieves stable limiting of fire hoses of different widths, ensuring no deviation during winding. After winding, pull slider 15. Slider 15 compresses strong tension spring 14, which drives positioning frame 17 to move through connecting frame 16. Positioning frame 17 drives turntable 18 and rotating sleeve 19 to move, causing linkage rod 13 to disengage from rotating sleeve 19, allowing the wound fire hose to be quickly removed.
