[0042] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] See also Figure 1-2 , portable hose reel, comprising:

[0044] A reeling component 10, which is used to reel in the hose. The reeling component 10 has two sets of hose clamping rods 101 arranged in parallel. The length of the hose clamping rods 101 must be greater than the width of the hose. The hose is wound around the two sets of hose clamping rods 101, so that the hose has a reeling center after being rolled up, and the reeling center is located between the two sets of hose clamping rods 101; and

[0045] The hand crank assembly 20 can perform a rotational action to drive the winding component 10 to rotate so as to wind up the water hose.

[0046] Specifically, the operating principle of the present reel is as follows: after folding the 40, 65, 80 type water hoses used at the fire scene in half, place the folded portion in the water hose clamp rod 101 of the reeling component 10 (the folded portion is placed on a group of water hose clamp rods 101 located at the top), and drive the reeling component 10 to rotate through the hand crank assembly 20 to quickly reel in the water hose; or place one end of the water hose used at the fire scene or the agricultural irrigation water hose on two groups of water hose clamp rods 101, and shake the hand crank assembly 20 to reel in the water hose; when reeling in the rope, you can reel in the middle of the rope or the end of the rope.

[0047] The reeling component 10 and the hand crank assembly 20 are the main structures of the reeling hose, and have the following two embodiments in specific applications:

[0048] In the first embodiment, as shown in the attached Figure 1 As shown, two groups of parallel arranged water hose clamp rods 101 are connected by setting a connecting plate 102, and the connecting plate 102 is located on the end surface on the same side of the two groups of water hose clamp rods 101 to support the parallel arrangement of the two groups of water hose clamp rods 101 without affecting the water hose being placed on the two groups of water hose clamp rods 101 from the other side for winding.

[0049] Further, the hand crank assembly 20 includes:

[0050] A rotating shaft 201, which is connected to the connecting plate 102 at a central position on a side opposite to the hose clamping rod 101 and is arranged parallel to the hose clamping rod 101; and

[0051] A hand crank 202 , the rotation axis of the hand crank 202 is coaxially connected to the rotation shaft 201 and is opposite to one end of the connecting plate 102 .

[0052] Specifically, the rotating shaft 201 is driven to rotate by manually shaking the hand crank 202, so as to drive the two groups of hose clamping rods 101 on the connecting plate 102 to rotate, so as to reel in the hose.

[0053] Furthermore, a winding trolley 30 is also included, and the winding trolley includes:

[0054] The frame 301, the rotating shaft 201 is rotatably arranged horizontally at the upper end of the frame 301 through a bearing;

[0055] A wheel axle 302, the wheel axle 302 is rotatably disposed at the lower end of the frame 301 through a bearing;

[0056] Wheels 303, wheels 303 are provided at both ends of the axle 302;

[0057] An adjustable telescopic rod 304, one end of which is connected to the vehicle frame 301 and the other end of which is connected to a push handle 305;

[0058] The fixing rings 306 are at least two groups arranged at the upper end of the outer side of the frame 301 for the adjustable telescopic rod 304 to be inserted into, so as to fix the adjustable telescopic rod 304 by pressing the tightening bolts on the frame 301, and the adjustable telescopic rod 304 is provided with a locking pin 307 at one end of the adjustable telescopic rod 304 opposite to the push handle 305 to prevent the adjustable telescopic rod 304 from being separated from the fixing ring 306; and

[0059] The transmission mechanism is disposed between the wheel axle 302 and the rotating shaft 201 to drive the rotating shaft 201 to rotate in one direction, so as to drive the winding component 10 to rotate and wind.

[0060] Specifically, the wheel 303 is used to walk on the ground, and during the walking process, the wheel axle 302 rotates synchronously therewith, and then the transmission mechanism between the wheel axle 302 and the rotating shaft 201 drives the rotating shaft 201 to rotate in one direction, wherein the adjustable telescopic rod 304 is pushed by the hand-held push handle 305 to push the entire frame 301 to move, so that the wheel 303 rotates, and then the transmission mechanism can be used to synchronously drive the winding component 10 to rotate and rewind in the process of pushing the winding cart 30 forward. The adjustable telescopic rod 304 telescopically moves in the fixed ring 306 to adjust the height of the adjustable telescopic rod 304 extending from the frame 301, so as to match the use of people of different heights, making the use of the retractor more flexible and convenient, and after adjusting the height, the tightening bolt on the frame 301 is tightened on the side of the adjustable telescopic rod 304 to fix the position of the adjustable telescopic rod 304.

[0061] Furthermore, the transmission mechanism comprises:

[0062] A first pulley 308, the first pulley 308 is coaxially arranged on the rotating shaft 201, and a one-way bearing is arranged between the first pulley 308 and the rotating shaft 201 to enable the first pulley 308 and the rotating shaft 201 to rotate in one direction;

[0063] A second pulley 309, which is rotatably coaxially disposed on the axle 302 via a bearing; and

[0064] The transmission belt 310 is disposed between the first pulley 308 and the second pulley 309 for belt transmission.

[0065] Specifically, the rotation of the wheel axle 302 drives the second pulley 309 to rotate. When the second pulley 309 rotates, the first pulley 308 is driven to rotate through the belt transmission of the transmission belt 310. At this time, a one-way bearing is provided between the first pulley 308 and the rotating shaft 201. In the present embodiment, it is set to push the winding trolley 30 forward. When the wheel 303 rotates, the rotating shaft 201 is driven to rotate synchronously through the transmission mechanism, thereby driving the winding component 10 to rotate synchronously, and the water hose will not scatter when it is reversed. On the contrary, when the winding trolley 30 is pulled to move in the opposite direction, the transmission mechanism cannot implement transmission due to the one-way bearing. At this time, the rotation of the first pulley 308 cannot drive the rotating shaft 201 to rotate. Therefore, after the water hose is wound, the winding trolley 30 can be pulled to move and transfer, so as to realize the transportation of the wound water hose without causing the winding component 10 to rotate at any time.

[0066] Furthermore, two sets of hose rollers 311 are arranged parallel to each other on the wheel axle 302, and the two sets of hose rollers 311 are located between the frame 301 and a set of wheels 303 at one end of the wheel axle 302;

[0067] Of the two groups of hose rollers 311: one group of hose rollers 311 close to the wheel axle 302 is fixedly arranged on the wheel axle 302, and one group of hose rollers 311 close to the wheel 303 is fixedly connected to the wheel axle 302 by tightening the threaded rod latch;

[0068] The distance between the two groups of water hose rollers 311 is set corresponding to the width of the water hose.

[0069] Specifically, the distance between the two groups of hose rollers 311 is set to correspond to the width of the hose, so that when the hose is rolled up, the hose moves between the two groups of hose rollers 311, which guides the position of the hose during the rolling process, so that the rolled hose is neatly rolled up. And according to the rolling work of hoses of different widths, the position of the group of hose rollers 311 close to the wheel 303 is adjusted to adjust the distance between the two groups of hose rollers 311, and the group of hose rollers 311 close to the wheel 303 is tightened on the wheel axle 302 through a threaded rod latch for fixed connection, or fixed by a limit fixing method such as a latch.

[0070] In the second embodiment, as shown in the attached Figure 2 As shown, among the two groups of hose clamp rods 101, one group is a rod structure, and the other group is a pipe structure. However, when reeling, the hose clamp rod 101 of the pipe structure still acts as a rod structure and cooperates with the other group of hose clamp rods 101 of the rod structure to reel the hose.

[0071] The two groups of parallel arranged water hose clamp rods 101 are connected by setting a connecting rod 103, and the connecting rod 103 is located on the end surface on the same side of the two groups of water hose clamp rods 101 to support the parallel arrangement of the two groups of water hose clamp rods 101 without affecting the water hose being placed on the two groups of water hose clamp rods 101 from the other side for winding.

[0072] Furthermore, the hand crank assembly 20 includes a crank handle 203, the rotation axis position of the crank handle 203 is coaxially connected to a group of hose clamp rods 101 of the pipe structure, and the crank handle 203 is located on the hose clamp rod 101 at one end opposite to the connecting rod 103. In this embodiment, the group of hose clamp rods 101 of the rod structure uses the group of hose clamp rods 101 of the pipe structure as the rotation axis, and is manually cranked and driven to rotate by the crank handle 203.

[0073] Furthermore, a winding support structure 40 is included. The winding support structure 40 is used to support the winding component 10 of this embodiment to rotate for winding. The winding support structure 40 includes:

[0074] A triangular bracket 401 is provided with a crossbeam 402 connected to the inner side of the triangular bracket 401, and a vertical plug rod 403 is vertically connected to the center position of the upper surface of the crossbeam 402. The vertical plug rod 403 extends into a group of hose clamp rods 101 of the pipe structure and is rotatably connected to the group of hose clamp rods 101 of the pipe structure through bearings, that is, the crossbeam 402 on the triangular bracket 401 plays a role in supporting the vertical plug rod 403, so that the group of hose clamp rods 101 of the pipe structure and the vertical plug rod 403 are rotatably connected through bearings, which plays a role in supporting the winding component 10 and also enables the winding component 10 to rotate and be wound under this support;

[0075] A main sub-clamping rod 404, wherein the three corner positions of the upper surface of the triangular bracket 401 are vertically provided with the main sub-clamping rod 404; and

[0076] Auxiliary sub-clamping rods 405 are provided on one side of any two adjacent groups of main sub-clamping rods 404 on the triangular bracket 401. The auxiliary sub-clamping rods 405 and the main sub-clamping rods 404 are arranged parallel to each other, and there is a space between the auxiliary sub-clamping rods 405 and the main sub-clamping rods 404 for the water hose to pass through.

[0077] Specifically, the space between the two sets of auxiliary sub-clamping rods 405 and the main sub-clamping rod 404 for the hose to pass through plays a guiding role in the position of the hose during the hose winding process, so that the hose is neatly wound during the winding process of the winding component 10. More specifically, if the hose is folded in half, the two ends of the hose placed in the winding component 10 are supported and guided by the two sets of auxiliary sub-clamping rods 405 and the main sub-clamping rod 404 respectively and wound, and one end of the hose is placed on the two sets of hose clamping rods 101, then only one set of auxiliary sub-clamping rods 405 and the main sub-clamping rod 404 are needed to support and guide the hose to be wound.

[0078] Furthermore, the triangular bracket 401 is fixedly connected to the fire truck. Specifically, according to the space layout on the fire truck, the triangular bracket 401 is fixed to an idle position of the fire truck by bolt connection or the like, so that the retractor can be used with the fire truck conveniently.

[0079] In another embodiment, the triangular bracket 401 can also be directly nailed to the ground by tools such as ground nails, so that the retractor can be put into use at the corresponding position at any time.

[0080] To sum up, the device is simple to operate, easy to carry, and saves time and effort. It can not only reel in the water hose after compromising, but also reel in a single head. It can be operated by one person or by two people at the same time. Especially in winter and at larger fire scenes, the water hose is used in large quantities, and the water hose hardens at low temperatures after it comes out of water. Reeling it in by people is not only time-consuming and labor-intensive, but also easily causes the risk of frostbite to rescue workers. Reeling it in by this reel can not only reduce the time that firefighters stay at the fire scene and shorten the time for collecting equipment, but also improve the efficiency of collecting equipment. At the same time, in the field of agricultural production to irrigate rice fields, the irrigation water pipes are not only large but also wide, and it is very laborious for individuals to reel them in. Most of the time is spent on reeling, which reduces the irrigation efficiency. Reeling it in by this reel can not only greatly shorten the farmers' reeling time, save time and effort, but also improve the irrigation efficiency.

[0081] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
