Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, specifically to a fire hose storage structure. Background Technology

[0002] Fire hoses are an important fire extinguishing device. After use, firefighters need to roll up and retract the fire hoses. During this process, residual liquid may remain in the fire hoses. If not cleaned properly, it will affect the service life of the hoses. Fire hoses are also large and heavy, which adversely affects the retraction work. It is time-consuming and laborious for firefighters to manually retract the hoses.

[0003] A search revealed that Chinese patent CN208838951U discloses a fire hose retraction device. This device incorporates a squeezing mechanism. The fire hose's head is passed through the gap between an upper and lower squeezing roller. When the head is placed on a winding device for winding, residual liquid in the rear of the hose is squeezed out by the upper and lower squeezing rollers as the winding process continues. However, considering the potential differences in thickness and material between fire hoses of different sizes, and the fixed gap between the upper and lower squeezing rollers, the squeezing effect is poor for thinner fire hoses. For thicker fire hoses, the squeezing process may cause wear on the hose surface. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a fire hose storage structure to solve the problem mentioned in the background art of the difficulty in adjusting the distance between the two squeezing rollers.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fire hose storage structure, including a support frame, the support frame being triangularly supported, a support rod fixedly connected to the top of the support frame, and a lifting handle fixedly connected to the support rod. By rotating the lifting handle, the wound fire hose can be removed for easy carrying. It also includes:

[0008] A take-up roller, which is rotatably connected to the support rod via a rotation limiting member;

[0009] A water-squeezing roller is located on one side of the take-up roller, and the take-up roller is located directly below the water-squeezing roller, with a small space between them. The fire hose is wound around the take-up roller. When the take-up roller rotates, the water-squeezing roller squeezes the fire hose. The water-squeezing roller and the take-up roller rotate and cooperate to discharge the residual water in the fire hose.

[0010] An adjustment component is provided on the rotation limiter for adjusting the gap between the squeezing roller and the winding roller, and for squeezing the fire hose.

[0011] Preferably, the rotation limiting member includes:

[0012] A rotating rod, one end of which is rotatably connected to the bottom of the support rod, and the other end of which passes through the take-up roller and is rotatably connected to the take-up roller;

[0013] The first limiting screen plate is rotatably connected to one end of the rotating rod, and one end of the first limiting screen plate is fixedly connected to one end of the winding roller;

[0014] The second limiting mesh plate has one end fixedly connected to the other end of the take-up roller. The first limiting mesh plate and the second limiting mesh plate fix the fire hose and play a guiding role to prevent the fire hose from overlapping or shifting.

[0015] A connecting rod, one end of which is fixedly connected to the other end of the second limiting mesh plate;

[0016] A crank handle, which is sleeved on the connecting rod and rotatably connected to the connecting rod.

[0017] Furthermore, the adjustment component includes:

[0018] A rotating shaft passes through the dewatering roller and is rotatably connected to the dewatering roller;

[0019] Two movable seats are fixedly connected to both ends of the rotating shaft, and the first limiting mesh plate and the second limiting mesh plate are each provided with a movable groove, and the movable seats slide in cooperation with the inner wall of the movable groove.

[0020] A telescopic rod, one end of which is fixedly connected to one end of the movable seat, and the other end of which is fixedly connected to the inner top wall of the movable groove;

[0021] A compression spring is provided, one end of which is fixedly connected to one end of the movable seat, and the other end of which is fixedly connected to the inner top wall of the movable groove. The telescopic rod is disposed inside the compression spring. During the process of the fire hose being wound on the take-up roller, the number of winding turns and the thickness increase. Through the cooperation of the adjusting component and the squeezing roller, the distance between the squeezing roller and the take-up roller can be increased, which also facilitates the squeezing of the fire hose.

[0022] Furthermore, both sides of the take-up roller and the squeezing roller are in contact with the side walls of the first limiting mesh plate and the second limiting mesh plate, and the distance between the first limiting mesh plate and the second limiting mesh plate is the same as the width of the fire hose.

[0023] As a further embodiment of this solution, the second limiting mesh plate has an empty groove for guiding one end of the fire hose.

[0024] Based on the aforementioned scheme, a fixed hook is fixedly connected to the second limiting mesh plate.

[0034] 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.

[0035] Please see Figures 1 to 4 This embodiment proposes a fire hose storage structure, including a support frame 1, which is triangularly supported, a support rod 2 is fixedly connected to the top of the support frame 1, and a lifting handle 3 is fixedly connected to the support rod 2. It also includes a winding roller 4, a squeezing roller 5, and an adjustment assembly.

[0036] like Figure 2 , Figure 3 As shown, the take-up roller 4 is rotatably connected to the support rod 2 via a rotating limiting component. The rotating limiting component includes a rotating rod 6, a first limiting screen plate 7, a second limiting screen plate 8, a connecting rod 9, and a crank handle 10. One end of the rotating rod 6 is rotatably connected to the bottom of the support rod 2, and the axis of the rotating rod 6 is located at the center of the top of the support rod 2 and the bottom of the support frame 1. The rotating rod 6 and the take-up roller 4 are coaxially connected. The other end of the rotating rod 6 passes through the take-up roller 4 and is rotatably connected to it. The first limiting screen plate 7 is rotatably connected to one end of the rotating rod 6 and is located on one side of the support rod 2. One end of the first limiting screen plate 7 is fixedly connected to one end of the take-up roller 4. One end of the second limiting screen plate 8 is fixedly connected to the other end of the take-up roller 4. The second limiting screen plate 8 has a slot 16 for... One end of the fire hose is guided, and a fixed hook 17 is fixedly connected to the second limiting mesh plate 8 to fix one end of the fire hose. One end of the connecting rod 9 is fixedly connected to the other end of the second limiting mesh plate 8. The crank handle 10 is sleeved on the connecting rod 9 and rotatably connected to the connecting rod 9. First, one end of the fire hose is passed around the take-up roller 4 and fixedly hung on the fixed hook 17 through the slot 16. By turning the crank handle 10, the crank handle 10 rotates outside the connecting rod 9, causing the connecting rod to make a circular motion around the axis of the take-up roller 4. The connecting rod drives the second limiting mesh plate 8 to rotate. The second limiting mesh plate 8 drives the fixed hook 17, the take-up roller 4 and one end of the fire hose to rotate. The take-up roller 4 drives the first limiting mesh plate 7 to rotate, thus winding the fire hose on the take-up shaft.

[0037] like Figure 3 , Figure 4 As shown, the squeezing roller 5 is located on one side of the take-up roller 4. The squeezing roller 5 and the take-up roller 4 rotate to discharge the residual water in the fire hose. Both sides of the take-up roller 4 and the squeezing roller 5 are in contact with the side walls of the first limiting mesh plate 7 and the second limiting mesh plate 8. The adjusting component is located on the rotating limiting component and is used to adjust the gap between the squeezing roller 5 and the take-up roller 4, and to squeeze the fire hose. The adjusting component includes a rotating shaft 11, two movable seats 12, a telescopic rod 14 and a compression spring 15. The rotating shaft 11 passes through the squeezing roller 5 and is connected to the squeezing roller 5. A rotatable connection is made, with two movable seats 12 fixedly connected to both ends of the rotating shaft 11 respectively. Movable grooves 13 are provided in both the first limiting mesh plate 7 and the second limiting mesh plate 8. The movable seats 12 slide against the inner walls of the movable grooves 13. One end of the telescopic rod 14 is fixedly connected to one end of the movable seat 12, and the other end is fixedly connected to the inner top wall of the movable groove 13. One end of the compression spring 15 is fixedly connected to one end of the movable seat 12, and the other end is fixedly connected to the inner top wall of the movable groove 13. The telescopic rod 14 is set... Inside the compression spring 15, one end of the fire hose is wrapped around the take-up roller 4 and fixed to the fixed hook 17 through the slot 16. By pulling the squeezing roller 5, the squeezing roller 5 squeezes the compression spring 15, causing both the compression spring 15 and the telescopic rod 14 to retract. This moves the moving seat 12 away from the take-up roller 4, which in turn moves the rotating shaft 11 and the squeezing roller 5 away from the take-up roller 4, increasing the distance between them. The fire hose is then placed between the squeezing roller 5 and the take-up roller 4. Subsequently, the take-up roller 4 is released, and the take-up roller 4 and the squeezing roller 5 together... The waterproof hose is squeezed flat, and then the crank handle 10 drives the take-up roller 4 to rotate. The fire hose is wound on the take-up roller 4. The squeezing roller 5 and the take-up roller 4 squeeze out the residual water in the fire hose. During the winding process, the number of winding turns increases and the distance between the take-up roller 4 and the squeezing roller 5 increases. The telescopic rod 14 and the compression spring 15 retract and drive the moving seat 12 to move in the moving groove 13. The compression spring 15 also generates elastic force on the moving seat 12, so that the squeezing roller 5 squeezes the fire hose to avoid poor water squeezing effect.

[0038] Working principle: During use, this fire hose storage structure increases the distance between the squeezing roller 5 and the take-up roller 4 by lifting the squeezing roller 5. The fire hose is then placed between the squeezing roller 5 and the take-up roller 4. The take-up roller 4 is then released, and the take-up roller 4 and squeezing roller 5 flatten the fire hose. One end of the fire hose is then wrapped around the take-up roller 4 and fixed to the fixed hook 17 via the slot 16. Finally, rotating the crank 10 causes the take-up roller 4 to move in a circular motion with its axis as the center. The movement of the connecting rod drives the second limiting mesh plate 8 to rotate, which in turn drives the take-up roller 4 to rotate outside the rotating rod 6. The take-up roller 4 drives the first limiting mesh plate 7 to rotate, thus winding the fire hose onto the take-up shaft. During the winding process, the squeezing roller 5 and the take-up roller 4 squeeze out the residual water in the fire hose. As the number of winding turns increases, the telescopic rod 14 and the compression spring 15 contract, adjusting the gap between the squeezing roller 5 and the take-up roller 4 and applying pressure to the fire hose to improve the water squeezing effect.

[0039] 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.
