Description

Technical Field

[0001] This utility model relates to the field of fire hose technology, and in particular to a reinforced fire hose. Background Technology

[0002] Reinforced fire hoses are mainly used in fire rescue environments and emergency high-pressure water supply conditions to achieve an organic combination of high-strength pressure resistance and efficient fire extinguishing delivery. Through the scientific composite structure design of the reinforcing layer and multiple wear-resistant and aging-resistant materials, the hoses are ensured to maintain structural stability and are not easily damaged in scenarios such as high-pressure water flow, frequent bending and dragging, and harsh environmental impacts. They are suitable for various high-intensity fire fighting operations such as building fire fighting, forest fire fighting, and emergency rescue.

[0003] The reinforced fire hose mainly consists of an outer layer, a middle layer, and an inner layer. Its working principle is that the outer layer is made of wear-resistant and aging-resistant synthetic materials, which effectively resists scratches from sharp objects and environmental erosion. The reinforcing layer is designed with a high-strength fiber braided structure, which significantly improves the overall pressure-bearing capacity of the hose and resists the expansion force brought by high-pressure water flow. The inner layer is made of smooth and water-impact-resistant materials, which reduces water flow resistance and enhances the resistance to water flow erosion. The various layers and components work together to enable the reinforced fire hose to operate normally in high-pressure fire water supply and rescue scenarios.

[0004] When using existing reinforced fire hoses, some hoses become excessively long and drag on the ground in confined spaces such as narrow indoor passages or complex industrial plant mezzanines. This not only causes them to get caught on obstacles, hindering operation, but also affects water flow pressure due to excessive bending. In outdoor sites requiring long-distance operations, the fixed length of the hose cannot meet the working distance, requiring operators to drag the hose back and forth, delaying rescue opportunities. It is difficult to flexibly adapt to the length requirements of fire hoses in different operating scenarios. Therefore, a reinforced fire hose is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a reinforced fire hose, which aims to improve the problem that the length of the hose cannot be adjusted according to different scenario requirements in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reinforced fire hose includes a fire hose, a connecting block fixedly connected to the rear end of the fire hose, a docking block fixedly connected to the rear end of the connecting block, a sliding shell slidably connected to the outside of the docking block, an installation block slidably connected to the outside of the docking block, a stop block slidably connected to the inside of the docking block, a sliding column fixedly connected to the inside of the stop block, a spring sleeved on the outside of the installation block, and a reinforcing component provided inside the fire hose.

[0008] As a further description of the above technical solution:

[0009] The reinforcing component includes a fire-fighting pipe, a safety layer fixedly connected inside the fire-fighting pipe, a buffer layer fixedly connected inside the fire-fighting pipe, and a protective layer fixedly connected inside the fire-fighting pipe;

[0010] As a further description of the above technical solution:

[0011] A rubber ring is fixedly connected to the front end of the mounting block, and the outside of the rubber ring is in contact with the inside of the sliding shell;

[0012] As a further description of the above technical solution:

[0013] The mounting block has a sliding groove inside, and the sliding column is slidably connected to the inside of the sliding groove.

[0014] As a further description of the above technical solution:

[0015] The mounting block is slidably connected inside the sliding shell, and the blocking block is slidably connected inside the mounting block;

[0016] As a further description of the above technical solution:

[0017] The blocking block is spherical in shape, and its top end is in contact with the interior of the sliding shell.

[0018] As a further description of the above technical solution:

[0019] The safety layer is fixedly connected to the right end of the fire pipe, and the left end of the buffer layer is fixedly connected to the right end of the safety layer.

[0020] As a further description of the above technical solution:

[0021] The left end of the protective layer is fixedly connected to the right end of the buffer layer, and the right end of the protective layer is fixedly connected to the left end of the fire pipe.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the sliding shell is slid to the designated position and the spring is compressed, so that the mounting block is slid into the outside of the docking block. The blocking block is squeezed and moves upward. It slides inside the mounting block through the sliding column. When the mounting block reaches the designated position, the blocking block is locked into the docking block to achieve pre-fixation. The sliding shell is slid backward to abut against the blocking block to prevent shaking. The compressed spring pushes it back to reset, preventing the sliding shell from sliding and completing the splicing of the fire hose. This allows the operator to adjust the length according to the working distance, solving the problem of redundancy in dragging the entire hose in the traditional way. The rubber ring can fill the gap between the sliding shell and the mounting block to prevent water from overflowing. When disassembling, the sliding shell is slid forward to slide the mounting block out of the docking block. The spring pushes the sliding shell back to reset, which is convenient for the next splicing.

[0024] 2. In this utility model, when fluids such as water and extinguishing agents flow into the fire pipe, the protective layer is in direct contact with the fluid, which can prevent leakage and maintain a seal even under long-term high-pressure transportation. When the fluid in the pipe generates pressure, the buffer layer will evenly distribute the pressure to prevent the hose from bursting due to excessive pressure. At the same time, it will prevent local tearing caused by bending or dragging by the operator. The safety layer is in direct contact with the external environment. With its own wear resistance, it provides isolation between the buffer layer and the protective layer, reducing the interference of external factors on the functions of both and ensuring the stable operation of the fire pipe 1.

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a reinforced fire hose, including a fire hose 1 for transporting fluids such as water and extinguishing agents required for firefighting. A connecting block 2 is fixedly connected to the rear end of the fire hose 1, serving to connect the fire hose 1 to a connecting block 3. The connecting block 3 is also fixedly connected to the rear end of the connecting block 2. The connecting block 3, in conjunction with an installation block 5, allows for splicing between the fire hoses 1. A sliding shell 4 is slidably connected to the outside of the connecting block 3, allowing the sliding shell 4 to fix a stop block 6. The mounting block 5 is slidably connected to the connecting block 3, and can slide outside the connecting block 3 to provide a foundation for splicing the fire pipe 1. The connecting block 3 is slidably connected to the inside of the connecting block 3, and can slide inside the connecting block 3 to complete the fixation between the mounting block 5 and the connecting block 3. The shape of the connecting block 6 is spherical. The spherical design allows the connecting block 6 to slide more smoothly when subjected to force. The top of the connecting block 6 contacts the inside of the sliding shell 4. Through the contact method, when the sliding shell 4 slides to the designated position, it can stop the connecting block 6 to prevent it from shaking.

[0033] A spring 8 is fitted around the outside of the mounting block 5. The spring 8 can be compressed when the sliding shell 4 slides, and can push the sliding shell 4 back to its original position to prevent it from sliding out of the mounting block 5. A rubber ring 9 is fixedly connected to the front end of the mounting block 5. The rubber ring 9 can enhance the sealing between the mounting block 5 and the sliding shell 4. The outside of the rubber ring 9 is in contact with the inside of the sliding shell 4. Through contact, it can fill the gap between the rubber ring 9 and the sliding shell 4 to prevent water from overflowing during operation. The fire pipe 1 is equipped with a reinforcing component inside. The reinforcing component can improve the overall strength of the fire pipe 1 and make it less likely to be damaged during operation. A sliding groove is opened inside the mounting block 5. The sliding groove provides directional and positional restrictions for the sliding column 7. The outside of the sliding column 7 is slidably connected to the inside of the sliding groove. Through the sliding connection, the stop block 6 slides inside the mounting block 5 along a predetermined trajectory to ensure the stability of the movement of the stop block 6.

[0034] Reference Figure 1 , Figure 2 and Figure 4The reinforcing components include a fire pipe 1, which provides a load-bearing foundation for the reinforcing components. A safety layer 10 is fixedly connected inside the fire pipe 1. The safety layer 10 is composed of fluororubber and provides basic safety protection for the interior of the fire pipe 1. A buffer layer 11 is fixedly connected inside the fire pipe 1. The buffer layer 11 is composed of aramid fiber woven mesh and nitrile rubber. The buffer layer 11 can buffer the impact force generated by the fluid flowing inside the fire pipe 1 and reduce the damage to the fire pipe 1 caused by water flow impact. A protective layer 12 is fixedly connected inside the fire pipe 1. The protective layer 12 is composed of polyethylene and can further improve the overall protective performance of the fire pipe 1 and resist external damage that may be caused to the fire pipe 1.

[0035] Safety layer 10 is fixedly connected to the right end of fire pipe 1. This fixed connection allows safety layer 10 to provide initial safety protection for fire pipe 1, ensuring its stable operation. Buffer layer 11 is fixedly connected to the right end of safety layer 10. This fixed connection allows buffer layer 11 to work in conjunction with safety layer 10, providing a buffering effect while maintaining safety. Protective layer 12 is fixedly connected to the right end of buffer layer 11. Protective layer 12 can withstand the pressure on buffer layer 11 and activate a certain buffering effect, forming continuous protection. Protective layer 12 is fixedly connected to the left end of fire pipe 1. This fixed connection allows protective layer 12 to effectively protect fire pipe 1. Together with safety layer 10 and buffer layer 11, they form a comprehensive and enhanced protection for fire pipe 1.

[0036] Working principle: When the operator uses the reinforced fire hose, slide the sliding shell 4 to the designated position at the front end and compress the spring 8, sliding the mounting block 5 into the outside of the docking block 3. At this time, the blocking block 6 moves upward under the pressure of the docking block 3. Under the action of the sliding column 7, the blocking block 6 slides inside the mounting block 5. When the mounting block 5 slides to the designated position outside the docking block 3, the blocking block 6 slides into the inside of the docking block 3, realizing the pre-fixation of the mounting block 5 on the docking block 3. Slide the sliding shell 4 to the designated position at the rear end, so that the sliding shell 4 abuts against the blocking block 6, preventing the blocking block 6 from shaking, and is simultaneously compressed. The spring 8 pushes the sliding shell 4 back to its original position, preventing the sliding shell 4 from sliding out of the mounting block 5, thus completing the splicing of the fire pipe 1. This allows the operator to adapt the length of the fire pipe 1 spliced ​​according to different distance requirements of the work scenario, avoiding the dragging redundancy caused by the traditional whole hose being too long. At the same time, the rubber ring 9 can fill the gap between the sliding shell 4 and the mounting block 5 to prevent water from overflowing during operation. When it is necessary to remove it, the sliding shell 4 is slid forward to the designated position, and the mounting block 5 is slid out of the docking block 3. The compressed spring 8 pushes the sliding shell 4 back to its original position, ready for the next splicing.

[0037] During the operation of reinforced fire hoses, when water, extinguishing agents, or other fluids flow into the interior of the fire hose 1, the protective layer 12 comes into direct contact with these fluids, preventing leakage. Even with long-term high-pressure transport, it can maintain a sealed state. When the fluid inside the hose generates pressure, the buffer layer 11 can evenly distribute the pressure to every part of itself, preventing the hose from bursting due to excessive pressure. It also prevents the operator from bending or dragging the fire hose 1, which could cause local tearing. The safety layer 10 comes into direct contact with the external environment. Through its wear resistance, weather resistance, and puncture resistance, it provides an isolation effect between the buffer layer 11 and the protective layer 12, reducing the interference of external factors on the function of the buffer layer 11 and the protective layer 12, and ensuring the stable operation of the fire hose 1.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
