[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 , Figure 2As shown, this utility model provides a manual fire hose reel, which consists of a support frame 1 that is assembled together during use and disassembled for storage after use, two support components 6 for straightening the fire hose, a rotating assembly 5 for winding the fire hose, and a crank 3 for rotating the rotating assembly 5. This reel is easy to assemble and disassemble, has a small size, effectively reduces the space occupied by the equipment box, and greatly improves space utilization.

[0021] The support frame 1 is triangular in shape and consists of a bottom support tube 8, two side support tubes 7, and roller bearings 10 connected to the upper ends of the two side support tubes 7. A short shaft 9 is inserted into the inner hole of the roller bearing 10, and the short shaft 9 and the roller bearing 10 are interference-fitted. The bottom support tube and the side support tubes are cut from 20×20×2 square steel tubes. The bottom of the side support tube 7 has a square through hole for assembling the support component 6.

[0022] The crank handle 3 is L-shaped, with a bakelite handle sleeve 2 fitted at one end and a stepped shaft with a cotter pin hole at the other end for connection with the short shaft 9. The end of the crank handle 3 with the stepped shaft passes through the crank handle connection hole on the short shaft and is locked by a cotter pin 4 inserted into the cotter pin hole.

[0023] The rotating assembly is engaged with a short shaft fixed to the roller bearing in the support frame. The rotating assembly is driven to rotate by the crank handle to wind up the water hose, which solves the problem of time-consuming, labor-intensive, and inefficient manual winding of water hoses due to their length and quantity.

[0024] like Figure 3 As shown, the rotating assembly 5 is welded together from a central shaft 12 and a rotating round bar 11. The central shaft 12 is made of a φ20 stainless steel round bar, and its rear end is a threaded stepped shaft. The rotating round bar 11 is L-shaped and made of a φ8 stainless steel round bar.

[0025] like Figure 4 As shown, one end of the short shaft 9 has an axial inner hole with an internal thread that mates with the external thread of the central shaft 12, and the other end has a radial crank handle connection hole.

[0026] like Figure 5 As shown, the support member 6 is L-shaped and made of φ8 stainless steel round bar. One end of the support member 6 is a square stepped shaft for connecting with the support frame 1.

[0027] The usage process of this utility model is as follows: First, assemble the support frame 1, support member 6, rotating assembly 5, and crank handle 3 together. Connect the external thread of the central shaft 12 of the rotating assembly 5 to the internal thread of the short shaft 9. Insert the two support members 6 into the square through hole at the bottom of the side support tube 7 via their square stepped shafts, and lock them with cotter pins. Insert the crank handle 3 into the crank handle connection hole on the short shaft 9 via its stepped shaft, and lock it with cotter pins. After assembly, place the retractor in the middle of the fire hose. Pass the fire hose through the support members 6 on both sides of the bottom of the support frame 1 in sequence. Then, pick up the fire hose and place it on the central shaft 12 of the rotating assembly 5 so that the fire hose is positioned between the central shaft 12 and the rotating rod 11. Hold the bakelite handle sleeve 2 and turn the crank handle 3. The short shaft 9 drives the rotating rod 11 in the rotating assembly 5 to rotate, thereby achieving rapid retraction of the fire hose. Meanwhile, during the hose reeling process, the support members 6 on both sides of the bottom of the support frame 1 can straighten the tangled hose. After the hose is reeled in, pick up the reel and remove the reeled hose from the handle-less side of the reel. Then, disassemble and store the support frame 1, support members 6, rotating assembly 5, and crank handle 3.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
