Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire-fighting equipment technology, specifically a fire hose dragging structure. Background Technology
[0002] Fire hoses are crucial equipment for delivering high-pressure water in firefighting and rescue operations. They are typically made of wear-resistant rubber, polyurethane, or high-strength fiber fabric, with a waterproof inner lining to ensure pressure resistance. Standard hoses are generally 20 or 25 meters long, and come in various diameters such as 50mm and 65mm. They can operate at pressures ranging from 1.0 to 4.0 MPa and withstand the impact of high-pressure water pumps. Both ends are equipped with quick-connect fittings (male / female snap-fit or clip-on connectors) to ensure rapid connection to fire hydrants and nozzles. High-quality hoses are tear-resistant, corrosion-resistant, and mildew-resistant; some newer hoses also have antifreeze and antistatic properties. After use, water should be drained, and the hoses hung to dry. Regular pressure tests should be conducted, and folding should be avoided to prevent aging of the inner lining. As the "lifeline" of the fire protection system, their reliability directly affects firefighting efficiency and rescue safety.
[0003] A search revealed that Chinese Patent Publication No. CN201906384U discloses a fire hose. This hose has a simple structure with a three-layer design: an inner lining layer, a braided layer, and a fireproof layer, from the inside out, which enhances its fire resistance. Several fluorescent strips are arranged along the circumference of the outer wall of the fireproof layer to increase its warning function, making it convenient for users. However, during use, repeated, multi-range water spraying for fire extinguishing and cooling is required around the fire point. Additionally, the hose placement area may be some distance from the fire point, necessitating dragging. This dragging method requires manually holding the outer ring of the hose or wrapping the hose around the arm and then leaning forward to apply force to move it to the desired location. Because the hose's surface is smooth, consisting of the inner lining layer, braided layer, and fireproof layer, it is prone to detachment and difficult to secure during dragging, increasing the inconvenience of the dragging process. 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 dragging structure that is easy to operate, allowing for easy dragging of fire hoses and reducing the inconvenience of transporting and transferring fire hoses during firefighting and rescue operations. Furthermore, its simple structure makes it easy to carry during use, thus solving the aforementioned technical problems.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a fire hose dragging structure, comprising a first folded rod, a second folded rod connected to the bottom end of the first folded rod, an upper clamping plate connected to the bottom end of the second folded rod, a connecting rod provided in the middle of the bottom end of the first folded rod, a spring connected to the bottom end of the connecting rod, and a sliding rod slidably connected to its outer circumference, a blocking block connected inside the sliding rod, and a movable handle connected to its top end, a lower clamping plate connected to the bottom end of the sliding rod, a sliding groove opened on the side of the second folded rod, and a slider installed on the side of the lower clamping plate.
[0008] As a preferred embodiment of this utility model, the bottom end of the first folded rod is welded to one side of the top end of the second folded rod to form a fixed structure, and one side of the bottom end of the second folded rod is welded to the end of the upper clamping plate to form a fixed structure. The first folded rod and the second folded rod form a main support structure.
[0009] As a preferred technical solution of this utility model, the upper surface of the second folded rod is provided with a sliding groove for the sliding rod to slide up and down.
[0010] As a preferred embodiment of this utility model, the bottom end of the spring abuts against the top end of the block, and the outer edge of the block is welded to the inside of the slide rod to form a fixed structure.
[0011] As a preferred technical solution of this utility model, the movable handle is wrapped with rubber material.
[0012] As a preferred embodiment of this invention, the outer wall of the slider is slidably connected to the inside of the groove.
[0013] As a preferred embodiment of this utility model, multiple sets of locking teeth are arranged at the bottom end of the upper clamping plate and the top end of the lower clamping plate.
[0014] Compared with the prior art, this utility model provides a fire hose dragging structure, which has the following beneficial effects:
[0015] 1. This utility model involves attaching the hose between the upper and lower clamping plates. Then, by inserting a finger through the first folding rod and grasping the movable handle, force is applied. As force is applied, the handle moves the sliding rod closer to the first folding rod, and the block, which is linked to it, moves upward simultaneously. This compresses the spring, causing the lower clamping plate to gradually move closer to the upper clamping plate. With the cooperation of the upper and lower clamping plates, the hose is firmly clamped, making it easy to drag. After dragging is complete, simply release the handle. The spring, which was compressed due to the force, will push the sliding rod and the block back to their original positions. At this point, the clamping force between the upper and lower clamping plates disappears, and the hose can be easily released, completing the dragging operation.
[0016] 2. In this utility model, as the lower clamping plate moves closer to the upper clamping plate driven by the sliding rod, the slider installed on the side of the lower clamping plate will slide synchronously along the sliding groove on the second folding rod, which improves the stability of the upper clamping plate when it moves and effectively avoids problems such as unstable clamping caused by shaking or displacement.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0023] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] Please see Figure 1-4A fire hose dragging structure includes a first folded rod 1, a second folded rod 2 connected to the bottom end of the first folded rod 1, an upper clamping plate 3 connected to the bottom end of the second folded rod 2, a connecting rod 4 provided in the middle of the bottom end of the first folded rod 1, a spring 5 connected to the bottom end of the connecting rod 4, and a sliding rod 6 slidably connected to its outer circumference, a blocking block 7 connected inside the sliding rod 6, and a movable handle 8 connected to its top end, a lower clamping plate 9 connected to the bottom end of the sliding rod 6, a sliding groove 10 opened on the side of the second folded rod 2, and a slider 11 installed on the side of the lower clamping plate 9.
[0026] Furthermore, a stable support structure is first formed by the first folding rod 1 and the second folding rod 2, which forms a main connecting frame for the towing device. During firefighting and rescue, the commanders and fighters attach the hose between the upper clamping plate 3 and the lower clamping plate 9, then pass their fingers through the first folding rod 1 and grasp the handle, applying force to the handle. Under the action of force, the handle moves the sliding rod 6 closer to the first folding rod 1. At the same time, the sliding rod 6 moves the blocking block 7 upward, squeezing the spring 5. At this time, the lower clamping plate 9 moves closer to the upper clamping plate 3. The hose is clamped and fixed by the upper clamping plate 3 and the lower clamping plate 9, which facilitates the towing of the hose.
[0027] Furthermore, since the hose is clamped between the upper clamping plate 3 and the lower clamping plate 9, it is easy for the hose to fall off during the dragging process. Therefore, multiple sets of clamping teeth are arranged at the bottom of the upper clamping plate 3 and the top of the lower clamping plate 9. The teeth of the multiple sets of clamping teeth increase the friction for fixing the hose, thereby increasing the clamping force of the hose and the friction of the hose, and preventing the hose from falling off during the dragging process.
[0028] Furthermore, since the handle is designed as a hard object with sharpened edges, it is easy for the hand to repeatedly rub against the hard object during long-term gripping, thereby increasing the discomfort of gripping. Therefore, the movable handle 8 is wrapped with rubber material to isolate the discomfort caused by the friction of the hard handle against the hand. At the same time, when the handle is subjected to pressure, the rubber will produce slight deformation, further conforming to the palm contour and forming a dynamic sealing effect to prevent accidental slippage.
[0029] Furthermore, when the sliding rod 6 moves the lower clamping plate 9 closer to the upper clamping plate 3, it causes the slider 11 to slide synchronously inside the slide groove 10, increasing the stability of the movement of the upper clamping plate 3.
[0030] Furthermore, after the dragging is completed, simply release the handle. The handle will cause the slide rod 6 and the block 7 to exert pressure on the spring 5, which will reset the slide rod 6 and release the force applied to the upper clamping plate 3, allowing the upper clamping plate 3 to move away from the lower clamping plate 9, thus releasing the clamping of the water hose and completing the dragging operation.
[0031] In use, first, attach the hose between the upper clamp 3 and the lower clamp 9. Then, insert your fingers through the first folding rod 1 and grasp the handle. Apply force to the handle, and the handle will move the sliding rod 6 closer to the first folding rod 1. At the same time, the sliding rod 6 will move the plug 7 upward, compressing the spring 5. This will move the lower clamp 9 closer to the upper clamp 3. The hose is then clamped and fixed by the upper clamp 3 and the lower clamp 9, making it easy to drag the hose. After dragging, simply release the handle. The pressure of the handle on the sliding rod 6 and the plug 7 on the spring 5 will allow the sliding rod 6 to return to its original position. Releasing the force applied to the upper clamp 3 will move the upper clamp 3 away from the lower clamp 9, thus releasing the hose clamp and completing the dragging operation.
[0032] 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.
