Technical Field

[0001] This utility model relates to the field of fire-fighting equipment, and in particular to a fire hydrant box. Background Technology

[0002] Fire hydrant boxes are indispensable and important equipment in fire protection systems. They are mainly used to store fire hoses, nozzles, fire hydrants, and other fire-fighting tools, and are key devices for quickly accessing fire-fighting equipment during fire emergency rescue. In the event of a fire, the speed at which the fire hydrant box can be opened and the efficiency of accessing its internal equipment directly affect the effectiveness and timeliness of fire rescue efforts; therefore, the rationality and functionality of its design are of paramount importance.

[0003] However, existing fire hydrant boxes have some shortcomings in practical applications. For example, traditional door opening methods typically rely on manual springs or simple mechanical structures, requiring significant force and being slow to open, potentially delaying rescue efforts. Furthermore, the internal equipment is often cluttered, with hoses, nozzles, and other components easily tangled, leading to inconvenience and even potentially hindering rescue efficiency due to misoperation. These problems mean that the actual performance of existing fire hydrant boxes in fire emergencies needs improvement, necessitating a more efficient and convenient fire hydrant box design to address these technical issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fire hydrant box. The torsion spring hinge and linkage mechanism enable the box door to open quickly, saving time and improving emergency response speed. The internal modular design with clear component partitions, combined with the telescopic rod and turntable, allows for quick retrieval of items, improving efficiency, reducing the risk of misoperation, and providing a guarantee for rescue.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire hydrant box, comprising a fire hydrant box, a torsion spring hinge provided on the left front end of the fire hydrant box, a box door rotatably connected to the left front end of the fire hydrant box via the torsion spring hinge, a switch cavity provided in the middle of the right end of the box door, a sliding rod slidably connected to the inner wall of the switch cavity, a fixed rod fixedly connected to the outer front wall of the sliding rod, a movable plate fixedly connected to the middle of the sliding rod, a spring sleeved on the outer left end of the sliding rod, a connecting rod fixedly connected to the left end of the sliding rod, a telescopic rod fixedly connected to the lower left side of the inner wall of the fire hydrant box, a turntable rotatably connected to the upper side of the drive end of the telescopic rod, and a winding roller fixedly connected to the upper end of the turntable.

[0006] Furthermore, one end of the spring is connected to one side of the movable plate, and the other end of the spring is connected to a fixed plate, with the outer wall of the sliding rod slidably connected to the inner wall of the fixed plate.

Detailed Implementation

[0024] 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.

[0025] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a fire hydrant box, comprising a fire hydrant box 1, a torsion spring hinge 3 provided on the left front end of the fire hydrant box 1, a torsion spring provided in the middle of the torsion spring hinge 3, a box door 2 rotatably connected to the left front end of the fire hydrant box 1 via the torsion spring hinge 3, a fire hydrant hose reel 12 provided on the upper right side inside the fire hydrant box 1, a water gun frame 14 fixedly connected to the upper left side inside the fire hydrant box 1 for holding a water gun, and a fire hydrant interface 13 provided on the lower right side inside the fire hydrant box 1.

[0026] Specifically, the fire hydrant box 1 has its door 2 located on the front left side, connected to the box body via a torsion spring hinge 3. During the closing process, the torsion spring accumulates elastic potential energy; when the door needs to be opened, this accumulated potential energy is released, allowing the door to open quickly and effectively shortening the operation time. The fire hydrant hose reel 12 is used to wind the fire hose; the nozzle frame 14 is specifically for holding the nozzle; and the fire hydrant connector 13 is used to connect the hose. The internal components of the fire hydrant box 1 are rationally arranged and their functions are clearly defined.

[0027] Reference Figure 2 , Figure 3 and Figure 5A switch chamber 18 is provided in the middle of the right end of the fire hydrant box 2. A switch door 4 is rotatably connected to the left front end of the switch chamber 18. A handle 5 is fixedly connected to the front side of the switch door 4. A rubber strip 19 is provided in the right front end of the switch chamber 18. A sliding rod 6 is slidably connected to the inner wall of the switch chamber 18. A fixed rod 7 is fixedly connected to the outer front side of the sliding rod 6. A moving plate 8 is fixedly connected to the middle of the sliding rod 6. A spring 9 is sleeved on the outer left end of the sliding rod 6. One end of the spring 9 is connected to one side of the moving plate 8. The other end of the spring 9 is connected to the fixed plate 10. The outer wall of the sliding rod 6 is slidably connected to the inner wall of the fixed plate 10. The front side of the fixed plate 10 is fixedly connected to the rear side of the fire hydrant box 2. A connecting rod 11 is fixedly connected to the left end of the sliding rod 6. The right end of the sliding rod 6 is slidably connected to the right front end of the fire hydrant box 1.

[0028] Specifically, when it is necessary to open the fire hydrant box 2, the operating steps are as follows: First, use the handle 5 to open the switch door 4; then, move the fixing rod 7 to the left. The fixing rod 7 only moves inside the switch cavity 18 and cannot drive the sliding rod 6 out of the switch cavity 18. When the fixing rod 7 moves, it will drive a series of components to move together, and the sliding rod 6, the moving plate 8, and the connecting rod 11 will move to the left. During the movement, the moving plate 8 will compress the spring 9, and at the same time, the connecting rod 11 will drive the limit rods at its upper and lower ends to move to the left together. When the sliding rod 6 and the limit rods at the upper and lower ends of the connecting rod 11 slide out from the front right side of the fire hydrant box 1, the box door 2 can be quickly opened under the action of the torsion spring hinge 3.

[0029] Reference Figure 2 and Figure 6 A telescopic rod 15 is fixedly connected to the lower left side of the inner wall of the fire hydrant box 1. A turntable 16 is rotatably connected to the upper side of the drive end of the telescopic rod 15. A winding roller 17 is fixedly connected to the upper end of the turntable 16. The winding roller 17 is used to wind the water hose.

[0030] Specifically, the winding roller 17 is used to wind the fire hose. When using the fire hose, moving the turntable 16 outward will extend the telescopic rod 15. The telescopic rod 15 has a manually extendable structure, and the turntable 16 and the fire hose will also extend out of the box together. At this time, holding one end of the fire hose will allow for quick release of the hose. This design greatly facilitates the use of the fire hose. Moreover, the reasonable layout inside the fire hydrant box 1 ensures that all components are securely placed, avoiding the occurrence of messy tangling of components.

[0031] Working principle: The front left side of the fire hydrant box 1 is connected to the box door 2 via a torsion spring hinge 3. When the box door 2 is closed, the torsion spring accumulates elastic potential energy. When the box door 2 is opened, the elastic potential energy is released, allowing the box door 2 to open quickly and reducing operation time. When the box door 2 needs to be opened, first open the switch door 4 using the handle 5, then move the fixed rod 7 to the left. The movement of the fixed rod 7 drives the sliding rod 6, the moving plate 8, and the connecting rod 11 to move to the left. The moving plate 8 then compresses the spring 9, and the connecting rod 11 drives the limit rods at its upper and lower ends to move to the left, so that the limit rods at the upper and lower ends of the sliding rod 6 and the connecting rod 11 slide out of the front right side of the fire hydrant box 1 at the same time, thus opening the box door 2. Under the action of the torsion spring hinge 3, the box door 2 opens quickly. The fire hydrant hose reel 12 is used to wind the fire hose, the water gun frame 14 is used to hold the water gun, and the winding roller 17 is used to wind the water hose. When in use, the telescopic rod 15 can be extended by moving the turntable 16 outward, and then the turntable 16 and the water hose will extend accordingly. The water hose can be quickly released by holding one end of the water hose. This setting makes it easy to remove the water hose.

[0032] 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.
