Its main function is to provide convenience for fire fighting operation and ensure the orderly storage and rapid deployment of fire fighting equipment, which is of great significance for controlling the spread of fire and protecting the safety of personnel and property.

[0003] In the prior art, a patent with the patent number CN202121924511.4 and the name of an integrated fire hose box with a self-contained heat tracing system discloses a fire hose box structure. In this structure, the fire hose is coiled on the fire reel inside the box body. This structure has some problems in actual use: when the hose needs to be pulled out for fire extinguishing operation, the pulling direction of the hose is not consistent with the output direction of the hose from the reel, which causes a certain resistance during the pulling of the hose. This not only prolongs the time of the fire fighters to take the fire hose and affects the fire extinguishing efficiency, but also in an emergency, the additional resistance may make it difficult for the fire fighters to operate the fire hose smoothly, causing the fire extinguishing action to be hindered, thus delaying the fire extinguishing opportunity and causing greater losses. In addition, the greater resistance may also cause damage to the fire hose itself, reducing the service life of the fire hose and increasing the maintenance cost.

[0004] In summary, the existing fire hose box structure has obvious deficiencies in the hose pulling operation, and needs to be improved to meet the demand for quick and efficient use of fire hoses in actual fire fighting operations. UTILITY MODEL CONTENTS

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] The following references Figures 1-5 will be used to illustrate the present application:

[0029] ​Embodiment: a fire-fighting device, comprising a box 1 and a reel 2, the box 1 serves as the shell of the entire device, which plays a role in containing, protecting the internal components and facilitating installation and fixation, providing a relatively stable storage space for the fire-fighting equipment, so as to prevent it from being disturbed and damaged by the external environment and ensure that the fire-fighting equipment can operate normally in critical moments. The reel 2 undertakes the task of winding the fire hose 8. Its design is directly related to the storage, release and convenience of use of the hose. When a fire occurs and the hose needs to be used for fire extinguishing operation, the hose 8 wound on the reel 2 must be smoothly and quickly pulled out, which requires the reel 2 to have reasonable structure and rotation performance.

[0030] It also includes an elongated swing arm 3, one end of which is rotatably connected to the box 1. This rotatable connection gives the swing arm 3 the ability to adjust the position flexibly.

[0031] The other end of the swing arm 3 is provided with a connecting hole 4 that penetrates it from top to bottom, and an L-shaped water inlet pipe is tightly connected in the connecting hole 4. The water inlet pipe is further divided into a vertical pipe part 5 and a horizontal pipe part 6. The vertical pipe part 5 is precisely rotatably connected in the connecting hole 4 and is axially fixedly connected with the connecting hole 4, which means that the vertical pipe part 5 can rotate around the shaft, but its own position along the axial direction is fixed, and such design ensures the stability of the connection between the water inlet pipe and the swing arm 3, avoiding problems such as loosening and displacement during use, thereby ensuring the reliability of the entire water supply system.

[0032] When the fire hose needs to be activated, the operator can easily rotate the swing arm 3 to conveniently rotate the reel 2 out of the box 1 by using the rotation function of the swing arm 3. This step effectively changes the initial position of the reel 2, so that it is no longer limited to a fixed orientation inside the box 1, thereby preliminarily adjusting the output direction of the hose, allowing the hose to stretch in a more convenient direction for use. More subtly, the rotation performance of the water inlet pipe itself, i.e. the rotation of the vertical pipe part 5 in the connecting hole 4 and the rotation of the reel 2 relative to the horizontal pipe part 6, can further finely adjust the position of the reel 2. Through this series of coordinated rotation operations, the final goal is achieved: the pulling direction of the hose is always highly consistent with the output direction of the hose from the reel. This consistency greatly optimizes the use process of the fire hose, reduces the resistance when pulling out the hose, and ensures that the fire-fighting personnel can deploy and use the fire hose at the fastest speed and most smooth operation in the fire-fighting action that is time-consuming, providing strong hardware support for timely extinguishing the fire and protecting life and property safety

[0033] It also includes a reel 2, which is rotatably connected with the horizontal pipe part 6.

[0034] The reel 2 comprises a center tube 9, both ends of which are connected with a disc body 10, the center tube 9 serving as a core support component of the reel 2, providing a stable connection basis for the disc body 10 at both ends, ensuring the structural strength of the entire reel 2, so that it can withstand the pressure brought by the winding of the fire hose 8 and the pulling force in the use process. The disc body 10 serves to provide a winding space for the fire hose 8 and can guide the orderly coiling of the hose 8, preventing the hose 8 from being wound in disorder during storage or use, and ensuring that the hose 8 can be smoothly paid out and retracted.

[0035] The connection mode of the cross pipe part 6 and the reel 2 is extremely innovative. The cross pipe part 6 extends into the center tube 9, and the two are rotationally connected through a bearing. The use of the bearing is the key to this connection design, which can effectively reduce the frictional resistance between the cross pipe part 6 and the center tube 9, so that the reel 2 can rotate smoothly and flexibly, and will not be stuck due to excessive friction, thereby ensuring that the fire hose 8 can be quickly and unobstructedly pulled out or retracted.

[0036] The cross pipe part 6 is also connected with the reel 2 through a rotary joint 7, which contains an inner core tube and an outer shell tube rotationally connected. The inner core tube is fixedly connected with the cross pipe part 6 and becomes an extension of the cross pipe part 6, ensuring the continuity of the water flow channel; the outer shell tube is fixedly connected with the center tube 9 and provides a support frame for the rotation of the inner core tube. This double-layer nested rotary joint 7 design further enhances the stability and flexibility of the connection between the cross pipe part 6 and the reel 2, allowing the reel 2 to rotate freely while ensuring the water supply line is not affected.

[0037] The vertical pipe part 5 of the water inlet pipe is responsible for connecting with the water supply network. As the starting end of the water source introduction, it must ensure the sealing and reliability of the connection to prevent water leakage and other problems from affecting the fire water supply effect. The cross pipe part 6 is connected with the hose through the adapter 7, and the ingenious part of this design is that when the reel 2 rotates due to various operation requirements, thanks to the above-mentioned bearing and rotary joint 7 and other ingenious designs, it will not cause any interference to the water supply of the cross pipe part 6. No matter how the reel 2 rotates and adjusts the position, the water flow can be continuously and stably delivered to the fire hose 8 through the water inlet pipe, the cross pipe part 6 and the adapter 7, providing uninterrupted water source guarantee for fire fighting operation, and meeting the stringent requirements of fire fighting work for water supply timeliness and stability.

[0038] The hose 8 is wound on the reel 2, and one end of the hose 8 is connected to the outer shell pipe through the central pipe 9. The water inlet pipe supplies water to the hose 8 through the inner core pipe and the outer shell pipe. In this way, a complete water supply path from the water inlet pipe to the hose 8 is formed. The water inlet pipe supplies water to the hose 8 through the inner core pipe and the outer shell pipe, the inner core pipe serves as a direct channel for water flow transmission, stably conveying the water source from the vertical pipe part 5 to the outer shell pipe, and the outer shell pipe not only plays a supporting and connecting role, but also cooperates with the inner core pipe to complete the water supply task of the hose 8, ensuring that water flow can continuously reach the end of the hose 8 during fire extinguishing, and providing sufficient water support for fire extinguishing operations.

[0039] The disc body 10 away from the water inlet pipe is detachably arranged. This design opens up a new way for the release of the fire hose 8. In some special fire extinguishing scenarios, the conventional pulling method of the hose 8 may not meet the requirements. For example, when there are complex obstacles in the fire scene, the hose cannot be pulled forward, or the hose needs to be laid quickly and over a long distance, the user can use this detachable structure. After the disc body 10 is detached, the user can take out all the hoses 8 wound on the reel at one time, then hold the hose 8, and release the hose 8 in time according to the direction of fire spread and the fire extinguishing demand, which greatly improves the flexibility and speed of hose laying, and can more efficiently cope with complex fire scenes.

[0040] The key to realizing the detachable function of the disc body 10 lies in the ingenious design of the central pipe 9. The central pipe 9 is provided with a plug hole 11 penetrating through itself in the radial direction, and a latch 12 is tightly connected in the plug hole 11, and the detachable disc body 10 is located on the inner side of the latch 12. In the daily state, the latch 12 is inserted into the plug hole 11, and the disc body 10 is stably fixed on the central pipe 9, ensuring the stability of the overall structure of the reel 2 and guaranteeing the normal winding and storage of the fire hose 8. When facing an emergency situation that requires a special hose release method, the user only needs to pull out the latch 12, and the disc body 10 loses the lateral fixing constraint, so that the disc body 10 can be easily detached, preparing for the subsequent flexible use of the hose 8. The whole process is simple and fast, and fully considers the high efficiency requirement of fire fighting operation in emergency state.

[0041] The two disc bodies 10 are provided with an expansion member 13, and the expansion member 13 is arranged in a spaced manner with the central pipe 9. The expansion member 13 is arc-shaped.

[0042] The expansion member 13 is fixedly connected with the disc body 10 close to the water inlet pipe. The stability of the expansion member 13 during the operation of the reel 2 is ensured, and displacement caused by vibration or other external factors is avoided, so as to affect the normal use of the whole device.

[0043] When the disc body 10 is disassembled according to the detachable design as described above, a space for a hand to reach into is naturally formed between the reamer 13 and the central tube 9. In actual fire fighting scenarios, time is pressing and the task is arduous, and the fireman needs to take the fire hose 8 at the fastest speed. At this time, the space intentionally left plays a key role, and the fireman does not need to waste effort to find other auxiliary tools or fumble a complex operation path, but only needs to directly reach into the space to stably hold the entire hose 8 wound on the central tube 9 and smoothly take it off.

[0044] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
