Description

Technical Field

[0001] This utility model belongs to the field of fire hose technology, and in particular relates to a multi-layer pressure-resistant and wear-resistant fire hose support device. Background Technology

[0002] In the prior art, a search revealed a Chinese patent that discloses "a multi-layer pressure-resistant and wear-resistant fire hose," with publication number "CN222400089U." This patent mainly includes a support frame and a winding reel. The surface of the winding reel is wound with the fire hose body, which includes a rubber waterproof layer. The outer surface of the rubber waterproof layer is wrapped with an inner protective layer, which includes a polyamide fiber layer and a polyester fiber layer. The outer surface of the inner protective layer is wrapped with a TPU waterproof layer.

[0003] During use, existing fire hoses lack supporting structures, causing them to come into direct contact with the ground. This not only accelerates the wear and tear on the outer layer of the hose but also makes it easy for it to be scratched by sharp objects on the ground, thus reducing its service life. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-layer pressure-resistant and wear-resistant fire hose support device. By setting up a support part, the problem of the water hose being in direct contact with the ground due to the lack of a support structure is solved. This not only accelerates the wear of the outer layer of the water hose, but also makes it easy to be scratched by sharp objects on the ground, thereby reducing the service life of the water hose.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a multi-layer pressure-resistant and wear-resistant fire hose support device, including a support base, and further including: a support part, which is disposed at the bottom of the support base; and a fixing part, which is disposed at the top of the support base; wherein, the top of the support base is provided with an installation groove, which is adapted to the fixing part.

[0007] Furthermore, the support includes an adjustment assembly installed at the bottom of the support base. The adjustment assembly includes two upper folding rod groups hinged to the bottom of the support base. Each of the two upper folding rod groups has an adjustment plate hinged to its end away from the support base. Each of the two adjustment plates has a lower folding rod group hinged to its end away from the adjustment plate. Each of the two lower folding rod groups has a base plate hinged to its end away from the adjustment plate. Two slide rods are slidably connected to the two adjustment plates. A bidirectional screw is threaded onto the two adjustment plates. Both ends of the bidirectional screw are fitted with a manual knob. There are four upper folding rod groups and four lower folding rod groups, which are hinged together by the two adjustment plates.

[0008] Furthermore, an adaptation component is provided on the adjustment component. The adaptation component includes a plurality of screws threaded to the base plate. A manual turntable is fixedly connected to the top of each of the screws, and a fixing foot is fixedly connected to the bottom of each of the screws. There are four screws, four manual turntables and four fixing feet on each screw, and they are symmetrically distributed.

[0009] Furthermore, the fixing part includes a fixing assembly, which is installed on the top of the support base. The fixing assembly includes several lower guide rollers disposed on the support base, with fire hoses slidably connected to the outer walls of the several lower guide rollers. Several sliding rods are fixedly connected to the top of the support base, with mounting frames slidably connected to the outer walls of the several sliding rods. Several upper guide rollers are rotatably connected to the inner walls of the mounting frames. The outer walls of the several upper guide rollers are all in contact with the fire hoses. Reset members are provided on the several sliding rods. The outermost layer of the fire hose is a protective layer, the middle layer is a wear-resistant layer, and the innermost layer is a waterproof layer. The reset members include springs wrapped around the outer walls of the several sliding rods. One end of each spring is fixedly connected to the support base, and the other end of each spring is fixedly connected to the mounting frame.

[0010] Furthermore, a limiting component is provided, which is installed on the fixing component; wherein, there are two limiting components, which are symmetrically distributed on the fixing component, and each limiting component includes two screw rods fixedly connected to the top of the support base, and the outer walls of the two screw rods are threaded with manual knobs; wherein, both screw rods pass through the mounting frame and are slidably connected to the mounting frame.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up a support unit, when using the support device, first turn the manual knob one on the outer wall of the double-sided screw. Under the guidance of the two slide rods one, the double-sided screw will drive the two adjusting plates on it to move away from each other. Since the two adjusting plates are respectively hinged to the upper folding rod group and the lower folding rod group, as the adjusting plates move, the two folding rods will unfold synchronously, pushing the base plate away from the support seat, completing the opening action of the support device. At this time, the fire hose can be placed away from the ground, avoiding direct contact with the ground. This not only effectively reduces the wear of the outer layer of the hose and prevents it from being scratched by sharp objects on the ground, thereby improving the service life of the hose, but also makes it easy to adjust the height of the device according to actual needs. It is also very convenient to store after use. If the ground is uneven, simply turn the manual turntable on each corner screw, and the screw will drive the fixed feet to move up and down until the device is adjusted to a horizontal state, which significantly improves the environmental adaptability of the device.

[0013] 2. By setting up a fixing part, when fixing the fire hose, first pass the hose through the fixed guide structure composed of multiple lower guide rollers and upper guide rollers. Then, simultaneously rotate the manual knobs on the outer walls of the two screws. As the manual knobs rotate, the mounting frames on the outer walls of the two screws will drive the multiple upper guide rollers on them to gradually approach the multiple lower guide rollers on the support base, thereby clamping and fixing the fire hose. This setting of lower and upper guide rollers can not only fix the hose, but also significantly reduce the friction when the hose moves, ensuring smooth and unobstructed hose delivery. It is worth noting that when the mounting frame approaches the support base, it will also compress the springs on the outer walls of the multiple sliding rods, allowing the springs to accumulate elastic potential energy. When it is necessary to release the limit on the fire hose, the springs release energy, providing power for the mounting frame to drive the multiple upper guide rollers to reset, achieving convenient and quick operation.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-5 As shown, this utility model is a multi-layer pressure-resistant and wear-resistant fire hose support device, including a support base 1, and further including: a support part 2, which is disposed at the bottom of the support base 1; and a fixing part 3, which is disposed at the top of the support base 1; wherein, the top of the support base 1 is provided with an installation groove, which is adapted to the fixing part 3.

[0025] The support 2 includes an adjustment assembly 21, which is mounted on the bottom of the support base 1; and an adaptation assembly 22, which is disposed on the adjustment assembly 21. The adjustment assembly 21 includes two upper folding rod assemblies 211 hinged to the bottom of the support base 1. An adjustment plate 212 is hinged to the end of each upper folding rod assembly 211 away from the support base 1. Lower folding rod assemblies 213 are hinged to the ends of each lower folding rod assembly 213 away from the adjustment plate 212. A base plate 214 is hinged to the end of each lower folding rod assembly 213 away from the adjustment plate 212. Two sliding rods are slidably connected to the two adjustment plates 212. 215. Two adjusting plates 212 are threadedly connected to bidirectional screws 216, and both ends of the bidirectional screws 216 are fitted with manual knobs 217. Four upper folding rods 211 and four lower folding rods 213 are provided, and they are hinged together by the two adjusting plates 212. The adapting component 22 includes several screws 221 threadedly connected to the base plate 214. A manual turntable 222 is fixedly connected to the top of each screw 221, and a fixing foot 223 is fixedly connected to the bottom of each screw 221. The screws 221 and their corresponding manual knobs... Four movable turntables 222 and four fixed feet 223 are provided, symmetrically distributed. By providing the support part 2, when using the support device, first rotate the manual knob 217 on the outer wall of the bidirectional screw 216. Under the guidance of the two sliding rods 215, the bidirectional screw 216 will drive the two adjusting plates 212 on it to move away from each other. Since the two adjusting plates 212 are respectively hinged to the upper folding rod group 211 and the lower folding rod group 213, as the adjusting plates 212 move, the two folding rods will unfold synchronously, pushing the base plate 214 away from the support seat 1, thus completing the support device's operation. When activated, the fire hose 312 is positioned away from the ground, avoiding direct contact. This not only effectively reduces wear on the outer layer of the hose and prevents it from being scratched by sharp objects on the ground, thus extending its service life, but also allows the device to be adjusted in height according to actual needs. It is also very convenient to store after use. If the ground is uneven, simply rotate the manual turntable 222 on each corner screw 221, and the screw 221 will drive the fixing feet 223 to move up and down until the device is adjusted to a horizontal position, significantly improving the device's environmental adaptability.

[0026] The fixing part 3 includes a fixing component 31, which is installed on the top of the support base 1; and a limiting component 32, which is installed on the fixing component 31. Two limiting components 32 are provided and symmetrically distributed on the fixing component 31. The fixing component 31 includes several lower guide rollers 311 disposed on the support base 1. Fire hoses 312 are slidably connected to the outer walls of the lower guide rollers 311. Several sliding rods 313 are fixedly connected to the top of the support base 1. A mounting frame 314 is slidably connected to the outer walls of the sliding rods 313. The inner walls of the mounting frame 314 are rotatably connected. The system includes several upper guide rollers 315, the outer walls of which are in contact with the fire hose 312. Several sliding rods 313 are equipped with reset components. The fire hose 312 has an outermost protective layer, a middle wear-resistant layer, and an innermost waterproof layer. The limiting assembly 32 includes two screw rods 321 fixedly connected to the top of the support base 1. The outer walls of both screw rods 321 are threaded with manual knobs 322. Both screw rods 321 penetrate the mounting frame 314 and are slidably connected to it. The reset components are wrapped around the outer walls of the sliding rods 313. The wall springs 316, one end of each spring 316 is fixedly connected to the support base 1, and the other end of each spring 316 is fixedly connected to the mounting frame 314. By setting the fixing part 3, when fixing the fire hose 312, the hose is first passed through the fixed guide structure composed of multiple lower guide rollers 311 and upper guide rollers 315. Then, the manual knobs 322 on the outer wall of the two screws 321 are rotated synchronously. As the manual knobs 322 rotate, the mounting frame 314 on the outer wall of the two screws 321 will drive the multiple upper guide rollers 315 on it to gradually approach the multiple lower guide rollers 315 on the support base 1. 11, thereby clamping and fixing the fire hose 312. This setting of the lower guide roller 311 and the upper guide roller 315 not only fixes the hose, but also greatly reduces the friction when the hose moves, ensuring that the hose is transported smoothly. It is worth noting that when the mounting frame 314 moves closer to the support base 1, it will also compress the springs 316 on the outer wall of multiple slide rods 313, allowing the springs 316 to accumulate elastic potential energy. When it is necessary to release the limit on the fire hose 312, the springs 316 release energy, providing power for the mounting frame 314 to drive the multiple upper guide rollers 315 to reset, realizing convenient and fast operation.

[0027] A specific application of this embodiment is as follows: When using the support device, first rotate the manual knob 217 on the outer wall of the bidirectional screw 216. Under the guidance of the two slide rods 215, the bidirectional screw 216 will drive the two adjusting plates 212 on it to move away from each other. Since the two adjusting plates 212 are respectively hinged to the upper folding rod group 211 and the lower folding rod group 213, as the adjusting plate 212 moves, the two folding rods will unfold synchronously, pushing the base plate 214 away from the support seat 1, completing the opening action of the support device. At this time, the fire hose 312 can be placed away from the ground, avoiding direct contact with the ground. This not only effectively reduces the wear of the outer layer of the hose and prevents it from being scratched by sharp objects on the ground, thereby improving the service life of the hose, but also makes it easy to adjust the height of the device according to actual needs. It is also very convenient to store after use. If the ground is uneven, simply rotate the manual turntable 222 on each corner screw 221, and the screw 221 will drive the fixed foot 223 to move up and down until the device is adjusted to a horizontal state, significantly improving the efficiency of the fire hose. The device's environmental adaptability is enhanced. When fixing the fire hose 312, the hose is first passed through a fixed guide structure composed of multiple lower guide rollers 311 and upper guide rollers 315. Then, the manual knobs 322 on the outer walls of the two screws 321 are rotated simultaneously. As the manual knobs 322 rotate, the mounting frames 314 on the outer walls of the two screws 321 drive the multiple upper guide rollers 315 on them to gradually approach the multiple lower guide rollers 311 on the support base 1, thereby clamping and fixing the fire hose 312. This method of using the lower guide rollers 311... The installation of 11 and the upper guide roller 315 not only fixes the water hose but also significantly reduces the friction when the water hose moves, ensuring smooth and unobstructed water hose transportation. It is worth noting that when the mounting frame 314 moves closer to the support base 1, it also compresses the springs 316 on the outer wall of multiple slide rods 313, allowing the springs 316 to accumulate elastic potential energy. When it is necessary to release the limit on the fire hose 312, the springs 316 release energy, providing power for the mounting frame 314 to drive the multiple upper guide rollers 315 to reset, achieving convenient and quick operation.
