[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 7As shown, the fire hose portable rack includes a U-shaped portable rack 1, a U-shaped limiting rod 2 and a hose body 3. The U-shaped portable rack 1 is a hollow tube, the U-shaped limiting rod 2 is solid, one end of the U-shaped limiting rod 2 is slidably inserted in the U-shaped portable rack 1, and the U-shaped limiting rod 2 is slidably connected to the U-shaped portable rack 1 through a blocking connection component 4. A positioning bolt 5 and an upper blocking rod 6 are connected to the U-shaped portable rack 1. The positioning bolt 5 is connected to a bearing 7 through a built-in connecting rod 13. A roller 8 is fixedly sleeved on the bearing 7. The hose body 3 is wound around the roller 8. The upper blocking rod 6 is used to limit the hose body 3 from above. The upper blocking rod 6 and the U-shaped limiting rod 2 are respectively installed with The upper limit part 9 and the lower limit part 10 are each provided with a limit strap 11. The limit strap 11 is used to tighten and limit the hose body 3 wrapped around the roller 8. When in use, the fire hose body 3 is wrapped around the roller 8. By sliding the U-shaped limit rod 2 in the U-shaped handheld frame 1, the blocking connection component 4 is cooperated with the U-shaped limit rod 2 to press and limit the hose body 3. By using the bearing 7 on the positioning bolt 5, the roller 8 can rotate smoothly, which is convenient for the rapid deployment and storage of the hose body 3. The upper blocking rod 6 performs a preliminary limit on the hose body 3 from above to ensure that the hose body 3 will not slip off at will. Subsequently, the water hose body 3 is further tightened and limited by the limiting straps 11 on the upper limit part 9 and the lower limit part 10. When the limiting straps 11 are tightened, the U-shaped limiting rod 2 slides in the U-shaped handheld rack 1, and the bottom of the rolled-up water hose body 3 is pressed and limited to ensure its stability during transportation or storage. At the same time, when the straps are untied, the U-shaped limiting rod 2 automatically slides downward to avoid affecting the laying of the water hose body 3, thereby improving the use efficiency and providing strong conditions for firefighting and rescue.

[0023] The ends of the limiting strap 11 are fixedly connected by a connecting buckle 12. When the hose body 3 is tightened, the connecting buckle 12 is close to the upper barrier rod 6. The width of the connecting buckle 12 is greater than the width of the upper limit portion 9. The upper barrier rod 6 is located on the inner side of the U-shaped portable frame 1, and the distance between the upper barrier rod 6 and the bottom of the U-shaped portable frame 1 is the same as the length of the U-shaped limiting rod 2. The hose body 3 is wrapped around the roller 8 and the limiting strap 11 is used to further tighten the hose body 3. The ends of the limiting strap 11 are fixedly connected by the connecting buckle 12, so that the U-shaped limiting rod 2 is pressed against the bottom of the hose body 3 to limit the hose body 3, ensuring that the hose body 3 is stably clamped between the upper barrier rod 6 and the U-shaped limiting rod 2. The connecting buckle 12 is set close to the upper barrier rod 6 and its width is greater than the width of the upper limit portion 9, so that the strap can pass through and be fixed smoothly, avoiding the problem of the limiting strap 11 offsetting and slipping out.

[0024] The blocking connection assembly 4 includes a cylindrical threaded sleeve 401 and a blocking connection nut 402. The cylindrical threaded sleeve 401 is threadedly connected to one end of the U-shaped limit rod 2. The cylindrical threaded sleeve 401 is slidably inserted in the U-shaped portable frame 1. The blocking connection nut 402 is threadedly connected to one end of the U-shaped portable frame 1. A large threaded hole is provided at one end of the blocking connection nut 402, and the large threaded hole is threadedly engaged with one end of the U-shaped portable frame 1. A small clearance hole is provided at the other end of the blocking connection nut 402. The diameter of the small clearance hole is the same as the diameter of the U-shaped limit rod 2. Through the threaded connection of the cylindrical threaded sleeve 401 and the U-shaped limit rod 2, and the sliding insertion of the cylindrical threaded sleeve 401 in the U-shaped portable frame 1, a stable and adjustable sliding connection of the U-shaped limit rod 2 in the U-shaped portable frame 1 is achieved. At the same time, the large threaded hole of the blocking connecting nut 402 is engaged with the thread at one end of the U-shaped handrail 1, and the small clearance hole is designed to intersperse and give way to the U-shaped limit rod 2, which not only enhances the stability of the connection, but also makes the position adjustment of the U-shaped limit rod 2 easier and more flexible.

[0025] The process of fixing the water hose body 3 is as follows: 1. Roll up the water hose body 3; 2. Place the connected positioning bolt 5, built-in connecting rod 13, bearing 7 and roller 8 in the middle of the rolled water hose reel and adjust them; 3. Put the positioning bolt 5 on the U-shaped portable frame 1 to connect the U-shaped portable frame 1 with the bearing 7 and roller 8; 4. Connect the U-shaped limit rod 2 to the U-shaped portable frame 1 through the blocking connecting nut 402; 5. Adjust and fix the placed water hose body 3 and the U-shaped limit rod 2 on the upper blocking rod 6 through the limiting strap 11 and the connecting buckle 12. The limiting strap 11 is a hook and loop Velcro strap.

[0026] Laying process of the hose body 3: Unfasten the connecting buckle 12, lift the U-shaped handrail 1, and detach the connecting buckle 12 and the two ends of the limiting strap 11 and drop them to the ground. The positioning bolt 5 slides downward on the U-shaped handrail 1, allowing the bearing 7, roller 8 and hose reel to naturally fall to the blocking connection nut 402, leaving space for the upper hose reel to rotate; the U-shaped limiting rod 2 naturally falls to the maximum extension point, leaving space for the lower hose reel to rotate; after pulling out the hose body 3 and fixing it at the external interface, the hose body 3 can be laid as the U-shaped handrail 1 moves and the bearing 7 and roller 8 rotate.
