[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1-6 As shown, a fire hydrant box includes a box body 1 and also includes:

[0027] A fire hydrant 2, on which a rotary valve 24 and a water outlet 25 are provided;

[0028] A water hose 3, a first end of which is fixedly connected to the water outlet 25;

[0029] The clockwork mechanism 22 includes a clockwork sleeve 223 . The clockwork sleeve 223 is driven to rotate to drive the rotary valve 24 to rotate.

[0030] Specifically, Figure 1 As shown, the first end of the water hose 3 is first fixedly connected to the water outlet 25 on the fire hydrant 2, and the other end is fixedly connected to the water gun 4, and the water hose 3 is arranged in a serpentine folded shape on the water hose storage rack 5 in the box body 1, the first end of the water hose 3 is connected to the water outlet 25 through the groove at the bottom of the water hose storage rack 5, and the water gun 4 is also placed on the water hose storage rack 5. By connecting the water hose 3 to the water outlet 25 and the water gun 4 in advance, when using it, there is no need to perform the connection steps, which saves firefighting time. Since the water hose 3 is arranged in a serpentine folded shape on the water hose storage rack 5 in the box body 1, when using it, just take the water gun 4 to the fire point, and the water hose 3 is directly stretched out with the movement of the water gun 4. Compared with the winding arrangement of the water hose 3 in the prior art, the step of unfolding the water hose 3 is omitted, which further saves firefighting time and is more convenient and quick to use.

[0031] Furthermore, when the fire point is reached, the clockwork sleeve 223 is directly driven to rotate. The rotation of the clockwork sleeve 223 drives the rotary valve 24 to rotate automatically through the connecting rod 23, thereby opening the water outlet 25, and spraying water to the fire point through the water hose 3 and the water gun 4 to extinguish the fire. There is no need for personnel to travel back and forth between the fire point and the fire hydrant position. After moving the water gun 4 to the fire point, the fire can be extinguished directly, which saves preparation time and does not require the cooperation of multiple people. It is more convenient and quick to use, is not limited by the number of people, can be operated by one person, and has stronger applicability.

[0032] It should be noted that the driving mechanism of the spring sleeve 223 can be a remotely controlled driving motor to drive the spring sleeve 223 to rotate; or a hydraulic rod drives the connecting rod to drive the spring sleeve 223 to rotate; or any technical means known to those skilled in the art can be used.

[0033] In the above technology, by directly driving the spring sleeve 223 to rotate, the spring sleeve 223 rotates to drive the rotary valve 24 to rotate automatically, thereby opening the water outlet 25, and spraying water to the fire point through the water hose 3 and the water gun 4 to extinguish the fire. There is no need for personnel to travel back and forth between the fire point and the fire hydrant position. After moving the water gun 4 to the fire point, the fire can be extinguished directly, which saves preparation time and does not require the cooperation of multiple people. It is more convenient and quick to use, is not limited by the number of people, can be operated by one person, and has stronger applicability.

[0034] As a further embodiment of the present invention, the clockwork mechanism 22 further includes a clockwork spring 222 and a housing 221 . A first end of the clockwork spring 222 is fixedly connected to an outer wall of a clockwork spring sleeve 223 , and another end thereof is fixedly connected to an inner wall of the housing 221 .

[0035] Specifically, Figure 3 As shown, the shell 221 is fixed on the fire hydrant 2 through the fixing column 21, the clockwork 222 is arranged in the shell 221, and the initial state is the tightened state, and the initial state of the clockwork sleeve 223 is the locked state. When in use, the water gun 4 is directly taken to the fire point, and the water hose 3 is directly stretched with the movement of the water gun 4. When the fire point is reached, the clockwork sleeve 223 is unlocked, and the clockwork 222 needs to restore the deformation. Since the end fixed to the inner wall of the shell 221 cannot move, the end fixed to the outer wall of the clockwork sleeve 223 drives the clockwork sleeve 223 to rotate to restore the deformation. Figure 5 As shown, the rotation of the clockwork sleeve 223 drives the rotary valve 24 to rotate automatically through the connecting rod 23, eliminating the need for personnel to travel back and forth between the fire point and the fire hydrant position, saving time, and eliminating the need for an additional driving source, thereby simplifying the structure and saving manufacturing costs.

[0036] As a further embodiment of the present invention, a locking groove 2221 is provided on the mainspring sleeve 223 .

[0037] Specifically, a connecting sleeve 251 is slidably provided on the water outlet 25, and a locking rod 254 is provided on the connecting sleeve 251. The locking rod 254 cooperates with the latch of the locking groove 2221 to lock the spring sleeve 223. The connecting ring 31 provided on the water hose 3 is fixedly connected with the connecting sleeve 251 by bolts to achieve the pre-fixation of the water hose 3 and the water outlet 25. A first spring 253 is provided between the connecting sleeve 251 and the water outlet 25. The initial state of the first spring 253 is a compressed state. The first spring 253 pushes the locking rod 254 on the connecting sleeve 251 to cooperate with the latch of the locking groove 2221 of the spring sleeve 223 to lock the spring sleeve 223 due to the need to restore the deformation. When the spring sleeve 223 is in the locked state, the spring 222 is in the tightened state, and the rotary valve 24 is in the closed state.

[0038] Furthermore, when it is necessary to extinguish a fire, the user can directly take the water gun 4 to the fire point, and the water hose 3 will be directly stretched out with the movement of the water gun 4. When the fire point is reached, the water hose 3 is pulled again to make the water hose 3 in a straight state, thereby stretching, stretching and arranging the water hose 3 to facilitate water flow. At the same time, by stretching the water hose 3, the connecting ring 31 is pulled to drive the connecting sleeve 251 to slide on the water outlet 25 and squeeze the first spring 253, thereby driving the locking rod 254 set on the connecting sleeve 251 to disengage from the locking groove 2221 of the spring sleeve 223, thereby completing the unlocking of the spring sleeve 223, and no additional driving source is required to unlock the spring sleeve 223, which further simplifies the structure and saves manufacturing costs. At the same time, the arrangement of the water hose 3 and the unlocking of the spring sleeve 223 are completed, thereby further reducing the preparation time and improving the firefighting efficiency.

[0039] Further, the spring sleeve 223 is unlocked, and the spring 222 needs to restore its deformation. Since the end fixed to the inner wall of the housing 221 cannot move, the end fixed to the outer wall of the spring sleeve 223 drives the spring sleeve 223 to rotate to restore the deformation. Figure 5 As shown, the rotation of the clockwork sleeve 223 drives the rotary valve 24 to rotate automatically through the connecting rod 23, eliminating the need for personnel to travel back and forth between the fire point and the fire hydrant position, saving time, and eliminating the need for an additional driving source, thereby simplifying the structure and saving manufacturing costs.

[0040] As a further embodiment provided by the present invention, limit blocks 2512 are symmetrically arranged on the connecting sleeve 251 .

[0041] Specifically, a sealing ring 252 is provided on the water outlet 25. When the fire point is reached, the water hose 3 is pulled again to make the water hose 3 in a straight state, thereby stretching, stretching and arranging the water hose 3 to facilitate water flow. At the same time, when the water hose 3 is stretched, the connecting ring 31 is pulled to drive the connecting sleeve 251 to slide on the water outlet 25 and squeeze the first spring 253, thereby driving the locking rod 254 provided on the connecting sleeve 251 to disengage from the locking groove 2221 of the spring shaft sleeve 223, thereby completing the unlocking of the spring shaft sleeve 223. When the connecting sleeve 251 moves to a predetermined position, the limiting block 2512 moves under the drive of the second spring and enters the limiting groove 255 provided on the water outlet 25 (the initial state of the second spring is a compressed state), thereby locking the connecting sleeve 251. Figures 4 to 6 As shown, at this time, the sealing ring 252 is located at the connection gap between the connecting sleeve 251 and the connecting ring 31, as shown in FIG. Figures 3 to 5 As shown, the connection between the connecting sleeve 251 and the connecting ring 31 is sealed more tightly, thereby effectively preventing water leakage at the connection between the water outlet 25 and the water hose 3 during fire extinguishing.

[0042] Furthermore, after the fire is extinguished, the pull rod 2511 is pulled, thereby driving the limit block 2512 to disengage from the limit groove 255. The first spring 253 pushes the locking rod 254 on the connecting sleeve 251 to move toward the spring sleeve 223 and abut against the outer wall of the spring sleeve 223 due to the need to restore its deformation. The rotary valve 24 is manually rotated, thereby driving the spring sleeve 223 to rotate in the opposite direction through the connecting rod 23, thereby tightening the spring 222. When the rotary valve 24 rotates to the preset position, the first spring 253 pushes the locking rod 254 on the connecting sleeve 251 to cooperate with the locking groove 2221 pin on the spring sleeve 223, and then the water hose 3 is folded and placed on the water hose storage rack 5 for convenient use next time. It should be noted that the connecting sleeve 251 cooperates with the keyway of the water outlet 25 to keep the connecting sleeve 251 in linear motion to prevent rotational dislocation during the sliding process.

[0043] Working principle: first, the first end of the water hose 3 is fixedly connected to the water outlet 25 on the fire hydrant 2, and the other end is fixedly connected to the water gun 4, and the water hose 3 is folded in a snake shape and arranged on the water hose storage rack 5 in the box body 1. The first end of the water hose 3 is connected to the water outlet 25 through the groove at the bottom of the water hose storage rack 5, and the water gun 4 is also placed on the water hose storage rack 5. By connecting the water hose 3 to the water outlet 25 and the water gun 4 in advance, when it is necessary to extinguish the fire, just take the water gun 4 to the fire point, and the water hose 3 is directly stretched with the movement of the water gun 4. When it reaches the fire point, pull the water hose 3 again to make the water hose 3 in a straight state, thereby stretching, stretching and arranging the water hose 3 to facilitate water flow. At the same time, by When stretched, the connecting ring 31 is pulled to drive the connecting sleeve 251 to slide on the water outlet 25 and squeeze the first spring 253, thereby driving the locking rod 254 set on the connecting sleeve 251 to disengage from the locking groove 2221 of the spring sleeve 223, thereby completing the unlocking of the spring sleeve 223. No additional driving source is required to unlock the spring sleeve 223, further simplifying the structure and saving the manufacturing cost. At the same time, the arrangement of the water hose 3 and the unlocking of the spring sleeve 223 are completed. The spring sleeve 223 is unlocked, and the spring 222 needs to restore the deformation. Since the end fixed to the inner wall of the shell 221 cannot move, the end fixed to the outer wall of the spring sleeve 223 drives the spring sleeve 223 to rotate to restore the deformation. Figure 5 As shown, the clockwork sleeve 223 rotates to drive the rotary valve 24 to rotate automatically through the connecting rod 23, thereby opening the water outlet 25, and spraying water to the fire point through the water hose 3 and the water gun 4 to extinguish the fire.

[0044] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
