Description

Technical Field

[0001] This utility model relates to the technical field of fire hose winding tools, and more specifically, to a fire hose quick winding and storage device. Background Technology

[0002] Fire hoses are flexible tubes used to transport high-pressure water or flame-retardant liquids such as foam. After use, fire hoses need to be coiled and stored to avoid affecting their next use.

[0003] However, in the existing technology, fire hose winding mostly relies on manual and random coiling, which has the disadvantages of low winding efficiency, easy messiness, poor compatibility with different widths of hoses, easy loosening after winding, and insufficient stability. In view of this, this utility model proposes a fire hose rapid winding and storage device. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fire hose quick coiling and storage device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire hose quick coiling and storage device, including a handle frame, with support frames welded to both sides of the outer wall of the handle frame, a hose guide structure fixedly installed on the top of each of the two support frames, a support plate welded to the bottom of the handle frame, a rotating disk rotatably mounted on the surface of the support disk, and two winding rods fixedly installed on the surface of the rotating disk, a rotating handle fixedly installed on the rear side of the rotating disk, and the rotating handle rotatably connected to the support disk through a bearing, the handle frame and the two support frames are all "T" shaped structures welded from two galvanized steel pipes.

[0006] As can be seen, when the hose is folded in half and placed over the outside of the two take-up rods, and then the rotating disc drives the take-up rods to rotate, the two ends of the hose move closer to the center, which greatly improves the hose take-up efficiency.

[0007] To flexibly adjust the distance between the upper and lower rotating rollers according to the width of the fire hose, ensuring stable guidance of the hose during winding and improving winding efficiency, the hose guiding structure preferably includes two support blocks, both welded to the top of a support frame, with a lower rotating roller rotatably mounted between the two support blocks. An upper rotating roller is positioned on top of the lower rotating roller. Rectangular grooves are formed through the surfaces of both support blocks, and movable seats are slidably disposed within each of the rectangular grooves. An adjusting screw is connected to the top of one of the movable seats. The upper rotating roller is rotatably connected between the two movable seats. The adjusting screw is threadedly connected to the corresponding support block, driving the corresponding movable seat to slide up and down within the rectangular groove to adjust the upper rotating roller.

[0008] In order to compress the hose after it is fully wound up by the extrusion disc and to limit the extrusion disc with a limiting nut to prevent the hose from detaching from the winding rod and to improve the stability of the hose after winding up, preferably, the extrusion disc is slidably and detachably mounted on the outside of both winding rods. The outside of the winding rod and the front side of the extrusion disc is provided with an external thread groove, and the limiting nut is threadedly installed on the outside of the winding rod through the external thread groove.

[0009] In order to lock the positioning plate and the support plate with positioning bolts after the water hose is wound up, and to limit the rotation handle to prevent it from rotating arbitrarily and causing the water hose to loosen, preferably, a positioning plate is provided on the outside of the rotation handle and near the rear side of the support plate. The positioning plate is fixedly connected to the rotation handle. Several interconnected threaded holes are provided at the connection between the positioning plate and the support plate. Positioning bolts are installed in the internal threads of the threaded holes.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. By folding the hose in half and looping it onto the winding rod, the rotating handle drives the rotating disk and winding rod to rotate, thus achieving winding. At the same time, the two ends of the hose move closer to the rotating disk under the action of the guide structure, reducing mess during the winding process and greatly improving the speed and efficiency of hose winding.

[0012] 2. The distance between the upper roller and the lower roller in the hose guide structure can be flexibly adjusted by adjusting the screw, which can adapt to fire hoses of different widths, ensure stable guidance during the winding process, avoid hose deviation or jamming, and improve the versatility of the device.

[0013] 3. After winding, the extrusion plate and the limit nut can effectively extrude and limit the water hose, preventing the water hose from detaching from the winding rod. At the same time, the positioning bolt can fix the rotating handle by locking the positioning plate and the support plate, preventing it from rotating unnecessarily and causing the water hose to loosen. This ensures the neatness and stability of the water hose after winding, making it convenient for subsequent storage and retrieval. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] As attached Figure 1-6 The fire hose quick coiling and storage device shown includes a handle frame 1, with support frames 2 welded to both sides of the outer wall of the handle frame 1. A hose guide structure is fixedly installed on the top of each of the two support frames 2. A support plate 3 is welded to the bottom of the handle frame 1. A rotating plate 4 is rotatably installed on the surface of the support plate 3, and two winding rods 5 are fixedly installed on the surface of the rotating plate 4. A rotating handle 6 is fixedly installed on the rear side of the rotating plate 4, and the rotating handle 6 is rotatably connected to the support plate 3 through a bearing. The handle frame 1 and the two support frames 2 are all "T"-shaped structures welded from two galvanized steel pipes.

[0023] Specifically, in this structure, when quickly coiling and storing the fire hose, the hose to be coiled is first folded in half along the center, and the folded part is placed over the outside of the two coiling rods 5. At this time, the two ends of the coiling hose are located at the hose guide structure of the corresponding support frame 2 and extend to both sides.

[0024] The operator manually rotates the rotary handle 6, causing it to rotate via the bearing and support plate 3. This rotation drives the rotary plate 4, which in turn winds up the hose through the two take-up rods 5. The two ends of the hose are brought closer together towards the rotary plate 4, maximizing the hose winding efficiency. This winding state is shown in the attached figure. Figure 6 As shown.

[0025] In this embodiment, as shown in the appendix Figure 1 , 4As shown in Figures 5 and 6, the water hose guiding structure includes two support blocks 7, both of which are welded to the top of the support frame 2. A lower rotating roller 8 is rotatably mounted between the two support blocks 7, and an upper rotating roller 9 is provided on the top of the lower rotating roller 8. A rectangular groove 10 is opened through the surface of each of the two support blocks 7. A movable seat 11 is slidably arranged inside each of the two rectangular grooves 10, and an adjusting screw 12 is connected to the top of one of the movable seats 11. The upper rotating roller 9 is rotatably connected between the two movable seats 11. The adjusting screw 12 is threadedly connected to the corresponding support block 7 and is used to drive the corresponding movable seat 11 to slide up and down inside the rectangular groove 10 to adjust the upper rotating roller 9.

[0026] Specifically, in this structure, the two ends of the water belt can be located between the corresponding upper roller 9 and lower roller 8, respectively. The operator can adjust the width of the water belt by rotating the adjusting screw 12, so that the adjusting screw 12 rotates with the support block 7, thereby driving the movable seat 11 to move up and down inside the rectangular groove 10 opened in the corresponding support block 7. The distance between the upper roller 9 and the lower roller 8 can be adjusted according to the width of the water belt. During the winding process, the lower roller 8 rotates between the two support blocks 7, and the upper roller 9 rotates between the two movable seats 11, thereby playing a good guiding role in the winding of the water belt and improving the winding effect.

[0027] In this embodiment, as shown in the appendix Figure 1 , 2 As shown in Figures 6 and 7, the two take-up rods 5 are slidably and detachably connected to the outside of the extrusion plate 13. The outside of the take-up rod 5 and the front side of the extrusion plate 13 are provided with an external thread groove. The outside of the take-up rod 5 is threaded with a limit nut 14 through the external thread groove.

[0028] Specifically, in this structure, after the water hose is completely wound up, in order to prevent the water hose from detaching from the outside of the two winding rods 5, the operator can slide the extrusion disc 13 onto the outside of the two winding rods 5, apply pressure so that the extrusion disc 13 extrudes the wound water hose. At the same time, two limit nuts 14 are installed on the outside of the winding rods 5 through external thread grooves to limit the extrusion disc 13, so that the extrusion disc 13 has a good extrusion and limiting effect on the water hose outside the winding rods 5, improving the stability of the water hose after winding.

[0029] In this embodiment, as shown in the appendix Figure 3 As shown, a positioning plate 15 is provided on the outside of the rotating handle 6 and near the rear side of the support plate 3. The positioning plate 15 is fixedly connected to the rotating handle 6. Several interconnected threaded holes 16 are provided at the connection between the positioning plate 15 and the support plate 3. Positioning bolts 17 are installed in the internal threads of the threaded holes 16.

[0030] Specifically, in this structure, after the water hose is wound up, in order to prevent the rotating handle 6 from rotating without cause, the rotating handle 6 drives the positioning plate 15 to rotate. Since the connection between the positioning plate 15 and the support plate 3 is provided with several interconnected threaded holes 16, the positioning bolt 17 is threaded into the threaded holes 16 at the positioning plate 15 and the support plate 3, thereby locking the positioning plate 15 and the support plate 3. The positioning plate 15 is fixedly connected to the rotating handle 6, thus limiting the rotation of the rotating handle 6 and preventing the water hose from loosening due to the rotation of the rotating handle 6 without cause.

[0031] Working principle of this utility model:

[0032] Before using this application, it is necessary to first check whether each structure can be used normally, and then use it in the order of use.

[0033] When in use, first fold the fire hose that needs to be wound up along the center part, and put the folded part over the outside of the two winding rods 5. The two ends of the hose extend to the hose guide structure of the corresponding support frame 2. According to the width of the hose, the operator rotates the adjusting screw 12, so that the adjusting screw 12 and the support block 7 rotate, driving the movable seat 11 to move up and down in the rectangular groove 10, thereby adjusting the distance between the upper roller 9 and the lower roller 8, so that the two ends of the hose are located between the upper roller 9 and the lower roller 8, preparing for subsequent winding.

[0034] The operator manually rotates the rotating handle 6, which is rotatably connected to the support plate 3 through the bearing, driving the rotating plate 4 to rotate, which in turn causes the two winding rods 5 to rotate to wind up the water hose. During the winding process, the lower rotating roller 8 rotates between the two support blocks 7, and the upper rotating roller 9 rotates between the two movable seats 11, which plays a good guiding role for the water hose. The two ends of the water hose move closer to the rotating plate 4, improving the winding efficiency.

[0035] After the water hose is completely wound up, in order to prevent the water hose from detaching from the outside of the winding rod 5, the operator slides the extrusion disc 13 onto the outside of the two winding rods 5, applies force to make the extrusion disc 13 squeeze the wound water hose, and at the same time installs the two limit nuts 14 through the external thread groove on the winding rod 5 to limit the extrusion disc 13, so that the extrusion disc 13 can squeeze and limit the water hose, thereby improving the stability of the water hose after winding.

[0036] After the hose is wound up and secured, to prevent the hose from coming loose due to the unwarranted rotation of the rotating handle 6, since the positioning plate 15 is fixedly connected to the rotating handle 6, rotating the rotating handle 6 aligns the positioning plate 15 with the threaded hole 16 of the support plate 3. The positioning bolt 17 is then threaded into the threaded hole 16 that connects the positioning plate 15 and the support plate 3, locking the positioning plate 15 and the support plate 3, thereby limiting the rotation of the rotating handle 6. Finally, the operator can pick up or move the wound hose through the handle 1.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
