Technical Field
[0001] This utility model relates to the field of fire protection technology, specifically to a hand-cranked hose reel. Background Technology
[0002] Fire hoses are flexible tubes used to transport high-pressure water or flame-retardant liquids such as foam. Both ends of a fire hose have metal connectors, allowing you to attach another hose to extend the distance or a nozzle to increase the liquid spray pressure. Fire hoses are essential equipment in fire drills and emergency rescue operations. Ensuring the effective deployment of the fire hose requires a secure coil; therefore, mastering fire hose coiling is an indispensable part of the daily training for firefighters.
[0003] Traditional fire hose coiling methods typically involve manual coiling. Manual coiling often results in loose coils, uncoiled coils, slow coiling speeds, and difficulty coiling stiff hoses, directly impacting the speed of hose deployment and connection. This can delay rescue efforts in emergencies. Fire hoses withstand high pressure and are made of stiff, thick nylon-lined material, making them difficult to coil and prone to kinking. The hose reels are often loose or even uncoiled, hindering rapid deployment and causing problems with coiling speed and looseness. Furthermore, a single coil of fire hose weighs approximately 4 kilograms. Manual coiling requires continuous hand-eye coordination and arm rotation, taking nearly 4 minutes to coil a single roll. This slow, inefficient, and physically demanding process is detrimental to the operator. Summary of the Invention
[0004] This utility model addresses the problems of existing fire hoses being difficult to coil, coiling too loosely, and coiling slowly. It provides a hand-cranked fire hose coiler that facilitates fire hose coiling operations, ensures a tight coiled loop, prevents the hose from unraveling, allows for quick ejection of the hose when swinging it, and enables rapid coiling, saving time and effort, reducing the time required for fire hose coiling, and lowering the labor intensity of operators.
[0005] To achieve the above objectives, the technical solution of this utility model is: a hand-cranked fire hose reel, comprising a bracket and a crank handle. The bracket includes a support frame and support legs, with the support frame connected to the support legs. One end of the crank handle passes through the support frame and is rotatably connected to it. A notch at one end of the crank handle forms two corresponding fixing clips. A hose reel is fixedly fitted onto the end of the crank handle that passes through the support frame. The notch at one end of the crank handle forms two fixing clips, which secure the fire hose. The operator can rotate the crank handle to easily reel in the fire hose, ensuring a tight and secure loop that is not prone to loosening. The hose reel prevents the fire hose from deviating during reeling.
[0006] One of the support legs is fixedly equipped with a guide assembly at its top, which corresponds to the fixing clip. The guide assembly includes a U-shaped rod and a rotating cylinder. One end of the U-shaped rod is fixedly connected to the support leg, and the other end forms a notch with the support leg. The rotating cylinder is rotatably sleeved on the horizontal part of the U-shaped rod. When coiling fire hoses, the guide assembly straightens the fire hoses, automatically aligning the coiled fire hoses, reducing the manual straightening process, and improving the efficiency of fire hose coiling.
[0007] Furthermore, the support frame has an inverted "Y" shape, with support legs connected to the lower ends of both inclined sections, and a handrail vertically installed at the upper end of the vertical section. The support legs provide support for the support frame, allowing operators to hold onto the handrail to stabilize the hose reel when coiling it.
[0008] Furthermore, a bearing is fixedly installed at the connection point of the inclined portions of the two support frames, and an arc-shaped groove matching the bearing is opened on the inner side of the upper end of the inclined portion of the support frame; one end of the crank handle is rotatably connected to the support frame through the bearing. The bearing facilitates the rotation of the crank handle, enabling easy coiling of the fire hose and allowing for quick coiling of the fire hose.
[0009] Furthermore, the hose reel includes an inner ring, an outer ring, and fixed rods. The inner ring is fixedly sleeved on the crank handle, and multiple fixed rods are arranged in a ring between the inner ring and the outer ring. The inner ring, the outer ring, and the fixed rods cooperate to form the hose reel, so as to prevent the fire hose from deviating during the hose reeling process.
[0010] Furthermore, one of the fixing clips is movably fitted with a pull-out sleeve, which facilitates the unwinding of the coiled fire hose.
[0011] The beneficial effects of this utility model through the above technical solution are as follows:
[0012] This utility model has a reasonable structure and good performance. It facilitates the coiling of fire hoses while ensuring that the coiled fire hose is tight and not prone to loosening or uncoiling. This allows the fire hose to be quickly thrown out when it is unloaded. It can also quickly coil the fire hose, increasing the speed of fire hose coiling, saving time and effort, shortening the time required for fire hose coiling, improving the efficiency of fire hose coiling, and reducing the labor intensity of operators.
[0013] This utility model uses two fixing clips formed by opening a notch at one end of the crank handle to fix the fire hose, so as to fix the fire hose before winding it up; the fire hose turntable can prevent the fire hose from winding off-center when winding it up; and the pull sleeve can be used to make it easy to unwind the wound fire hose.
[0014] This invention utilizes bearings to facilitate the rotation of the crank handle, while the accompanying components help to straighten the fire hose. This allows the fire hose to be positioned at the U-shaped rod and rotating drum, automatically aligning the wound fire hose. This reduces the need for manual straightening of the fire hose, making it easier to coil and quickly coil the fire hose, thus improving the efficiency of fire hose coiling.
[0015] This invention utilizes the bearing to enable the crank handle to rotate the fire hose from bottom to top, allowing even hard fire hoses to be easily coiled. Compared to the uneven force of manual coiling, the fire hose coils produced by the coiler are tight, easy to use, and do not fall apart. At the same time, it saves time and effort, shortens the time required to coil the fire hose, improves the efficiency of fire hose coiling, and reduces the labor intensity of operators.

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0022] like Figures 1-4 As shown, a hand-cranked fire hose coiler includes a bracket and a handle 5. The bracket includes a support frame 1 and support legs 2, with the support frame 1 connected to the support legs 2. One end of the handle 5 passes through the support frame 1 and is rotatably connected to it. A notch 6 is provided at one end of the handle 5 to form two corresponding fixing clips 7. A hose reel is fixedly fitted onto the end of the handle 5 that passes through the support frame 1. In this embodiment, there are two support legs 2, which support the support frame 1. The handle 5 has a "Z"-shaped structure. Two corresponding fixing clips 7 are formed by the notch 6 at one end of the handle. When coiling the fire hose, the fire hose can be folded in half, and the folded end can be fitted onto the fixing clips 7. The fixing clips 7 secure the fire hose, facilitating coiling. The hose reel prevents the fire hose from deviating during coiling. The hose reel is welded and fixed to the handle 5.
[0023] One of the supporting legs 2 has a connecting component fixedly installed on its top, corresponding to the fixing clip 7. The connecting component includes a U-shaped rod 11 and a rotating cylinder 12. One end of the U-shaped rod 11 is fixedly connected to the supporting leg 2, and the other end forms a notch with the supporting leg 2. The rotating cylinder 12 is rotatably sleeved on the horizontal part of the U-shaped rod 11. In this embodiment, one end of the U-shaped rod 11 is welded and fixed to the top of the supporting leg 2, and the other end of the U-shaped rod 11 does not contact the supporting leg 2, forming a notch. That is, the two vertical parts of the U-shaped rod 11 have different lengths. The purpose of this is because the end of the fire hose is connected to a metal joint, which cannot pass through the U-shaped rod 11. When the fire hose is coiled, it is convenient to move the end of the fire hose out of the notch of the U-shaped rod 11. The rotating cylinder 12 facilitates the movement of the fire hose through the U-shaped rod 11.
[0024] The support frame 1 has an inverted "Y" shape. The lower ends of the two inclined sections of the support frame 1 are connected to the support legs 2, and a handrail 3 is vertically installed at the upper end of the vertical section of the support frame 1. In this embodiment, the inverted "Y" shape of the support frame 1 aims to improve the overall stability of the hose reel. The two support legs 2 support the support frame 1, thereby enhancing the stability of the hose reel. When reeling fire hoses, the operator can also step on the support legs 2 to ensure the stability of the support structure. The handrail 3 is parallel to the support legs 2 and the fixing clip 7, and is located above the fixing clip 7. When reeling fire hoses, the operator can hold onto the handrail 3 to further ensure the stability of the hose reel.
[0025] A bearing 4 is fixedly installed at the connection of the inclined portions of the two support frames 1. An arc-shaped groove matching the bearing 4 is opened on the inner side of the upper end of the inclined portion of the support frame 1. One end of the crank handle 5 is rotatably connected to the support frame 1 through the bearing 4. In this example, the arc-shaped groove provides an installation position for the bearing 4 to facilitate its fixation. The angle of the arc-shaped groove is 120°. The outer ring of the bearing 4 is welded and fixed to the inclined portion of the support frame 1, and the inner ring of the bearing 4 is interference-fitted with the crank handle 5 and welded and fixed to the crank handle 5. The crank handle 5 is rotated by the action of the bearing 4, thereby facilitating the coiling operation of the fire hose.
[0026] The hose reel includes an inner ring 8, an outer ring 9, and fixing rods 10. The inner ring 8 is fixedly sleeved on the crank handle 5, and multiple fixing rods 10 are arranged in a ring between the inner ring 8 and the outer ring 9. In this embodiment, the inner ring 8 is welded and fixed to the crank handle 5, and there are seven fixing rods 10. The two ends of the fixing rods 10 are welded and fixed to the inner ring 8 and the outer ring 9, respectively.
[0027] One of the fixing clips 7 is movably fitted with a pull-out sleeve 13. In this embodiment, before the fire hose is rolled up, the pull-out sleeve 13 can be fitted onto the fixing clip 7. When the fire hose is about to be rolled up, the pull-out sleeve 13 can be pulled off, thereby making it easy to remove the fire hose roll from the crank handle 5.
[0028] The working principle of this utility model is as follows: First, fully extend the fire hose to be coiled and lay it flat on the ground. Then, fold the fire hose from one end to the other. Then, pass the folded end of the fire hose through the U-shaped rod 11 and insert it between the two fixing clips 7. Use the fixing clips 7 to hold the folded end of the fire hose in place. Then, put the pull-out sleeve 13 on the fixing clip 7 located below. Then, the operator can step on one of the support legs 2, hold the hose reel with the left hand to assist in coiling, and turn the crank handle 5 with the right hand to drive the hose reel and fixing clips 7 to rotate. Then, the fire hose can be wound on the fixing clips 7 and pull-out sleeve 13 through the U-shaped rod 11 and the rotating cylinder 12. When the fire hose is about to be coiled, pull out the pull-out sleeve 13. Then, the fire hose roll can be removed and straightened. Finally, remove the end of the fire hose from the notch of the U-shaped rod 11 to complete the coiling operation of the fire hose.
[0029] The embodiments described above are merely preferred embodiments of the utility model and are not intended to limit the scope of the utility model. Therefore, all equivalent changes or modifications made to the technical solutions described in the scope of the utility model patent application should be included within the scope of the utility model patent application.
