[0020] To solve this technical problem, this utility model provides a portable manual fire hose reel, which is used for reeling fire hoses.

[0021] For details, please refer to Figures 1-3 Portable manual fire hose reels specifically include: The base frame 1 has a column 102 on its top. A first winding rod 201 is rotatably connected to the column 102 via a bearing. A crank 203 is fixedly connected to one end of the first winding rod 201. A first baffle 2 is provided on the outer surface of the first winding rod 201. A second winding rod 202 is also connected between the first baffle 2 and the first winding rod 201.

[0022] The portable manual fire hose reel provided by this utility model features a first reel 201, a second reel 202, and a crank 203. By turning the crank 203, the first and second reel 201 and the second reel 202 can be rotated to wind the fire hose between them. During the storage process, the base frame 1 and the column 102 provide support, allowing firefighters to turn the crank 203 without bearing the weight of the entire hose, thus reducing the physical burden on firefighters and lowering the risk of fatigue caused by prolonged operation.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1, please refer to Figures 1-3 A portable manual fire hose reel includes a base frame 1, with a column 102 on top of the base frame 1. A first reel 201 is rotatably connected to the column 102 via a bearing. A crank 203 is fixedly connected to one end of the first reel 201. A first baffle 2 is provided on the outer surface of the first reel 201, and a second reel 202 is connected between the first baffle 2 and the first reel 201. By turning the crank 203, the first reel 201 and the second reel 202 can be rotated to wind the fire hose between the first reel 201 and the second reel 202. During the winding process, the support of the base frame 1 and the column 102 allows the firefighter to only need to turn the crank 203 without bearing the weight of the entire hose, reducing the physical burden on the firefighter and lowering the risk of fatigue due to prolonged operation.

[0027] Example 2 further optimizes the portable manual fire hose reel provided in Example 1. Specifically, the first reel rod 201 and the second reel rod 202 are fixedly connected to the first baffle 2. The first baffle 2 can limit the fire hose, improve the stability of the fire hose during reeling, and reduce the occurrence of looseness and mess. The stable reeling process not only makes the hose storage more efficient, but also reduces the damage that the hose may suffer due to looseness during transportation and storage.

[0028] Example 3 further optimizes the portable manual fire hose reel provided in Example 1, specifically, as follows: Figure 2 As shown, a connecting plate 207 is fixedly connected to one end of the second take-up rod 202. The connecting plate 207 is fixedly sleeved on the outer surface of the first take-up rod 201. The first baffle 2 is inserted and connected to the outer surfaces of the first take-up rod 201 and the second take-up rod 202. The first take-up rod 201 and the second take-up rod 202 are connected through the connecting plate 207, so that the first baffle 2 can be removed from the first take-up rod 201 and the second take-up rod 202, which greatly facilitates the disassembly of the first baffle 2, brings great convenience to the maintenance and use of the equipment, and improves the operability and practicality of the equipment.

[0029] Example 4 further optimizes the portable manual fire hose reel provided in the above embodiments, specifically, as follows: Figure 1 As shown, a second baffle 206 is sleeved between the outer surfaces of the first winding rod 201 and the second winding rod 202. The outer surface of the first winding rod 201 is also sleeved with a sleeve 204 that is fixedly connected to the second baffle 206. The second baffle 206 and the first baffle 202 cooperate with each other to limit the fire hose during the winding process.

[0030] Furthermore, such as Figure 1 As shown, a first hand-tightening bolt 205 is threaded onto the sleeve 204. One end of the first hand-tightening bolt 205 is inserted into the sleeve 204 and contacts the first winding rod 201. Tightening the first hand-tightening bolt 205 can fix the position of the sleeve 204 and the second baffle 206. Loosening the first hand-tightening bolt 205 can push the second baffle 206 to move. On the one hand, the distance between the first baffle 206 and the second baffle 206 can be adjusted. On the other hand, the second baffle 206 can be removed after winding is completed so that the fire hose can be taken off.

[0031] Example 5 further optimizes the portable manual fire hose reel provided in the above embodiments, specifically, as follows: Figure 1 As shown, the bottom end of the column 102 is fixedly connected to the base frame 1.

[0032] In use, first remove the second baffle 206 from the first retractor 201, bend the fire hose and place it on the outer surface of the first retractor 201, then install the second baffle 206. Turn the crank 203 to drive the first retractor 201 and the second retractor 202 to rotate, so that the fire hose is wound around the outer surface of the first retractor 201 and the second retractor 202. After winding is completed, loosen the first hand-tightening bolt 205 and remove the second baffle 206. Then pull the fire hose to remove the wound fire hose.

[0033] Example 6 further optimizes the portable manual fire hose reel provided in Examples 1, 3, or 4 above. Specifically, as follows: Figures 3-5 As shown, the top of the base frame 1 is connected to a connecting plate 3 via a rotating shaft. The connecting plate 3 has several first through holes 301. The base frame 1 is threaded with a second hand-tightening bolt 302. The second hand-tightening bolt 302 is inserted into one of the first through holes 301. After unscrewing the second hand-tightening bolt 302, the column 102 can be rotated.

[0034] Furthermore, such as Figures 3-4 As shown, a first connecting seat 303 is fixedly connected to both sides of the top of the connecting plate 3, and a connecting shaft 304 is fixedly connected between the two first connecting seats 303. A second connecting seat 305 is sleeved on the outer surface of the connecting shaft 304. The second connecting seat 305 is fixedly connected to one end of the column 102, and the column 102 can rotate around the connecting shaft 304.

[0035] Furthermore, such as Figures 3-4 As shown, the second connecting seat 305 has two second through holes 307. A third hand-tightening bolt 306 is threaded onto one of the first connecting seats 303. One end of the third hand-tightening bolt 306 is inserted into one of the second through holes 307. The position of the column 102 can be fixed by inserting the third hand-tightening bolt 306 into the second through hole 307. The column 102 can be folded after the third hand-tightening bolt 306 is unscrewed.

[0036] Furthermore, such as Figure 1 As shown, limit plates 4 are fixedly connected to the four corners of the top of the base frame 1. After the first baffle 2 and the second baffle 206 are removed, they can be placed on the top of the base frame 1 and horizontally limited by the limit plates 4. The first baffle 2 and the second baffle 206 are folded by the position of the column 102 after the column 102 is folded, that is, the whole can be folded to improve portability.

[0037] When folding, remove the first baffle 2 and the second baffle 206 and place them on top of the base frame 1. Then, unscrew the second hand-tightening bolt 302 and the second through hole 307, fold the column 102 toward the first baffle 2 and the second baffle 206, and then loosen the second hand-tightening bolt 302 and the second through hole 307, as shown. Figure 5 As shown, when unfolding, unscrew the second hand-tightening bolt 302 and the second through hole 307, then stand the column 102 upright and rotate it back to its original position, screw on the second hand-tightening bolt 302 and the second through hole 307, and then install the second baffle 206 and the first baffle 2 onto the first winding rod 201 and the second winding rod 202.
