[0002] A fire hydrant is a fixed fire-fighting facility, whose main function is to control combustibles, isolate combustibles, and eliminate fire sources. When the fire hydrant needs to be used, the handwheel on the top of the fire hydrant can be turned to open the valve. The handwheel has certain defects when used, so there are some sprinkler fire hydrants that have made improvements on the handwheel.

[0003] Patent No. CN217630250U discloses a lockable sprinkler fire hydrant for fire protection engineering. By setting an operating column, a connecting block and a fixing bolt, the groove opening of the connecting block is aligned with the fixing bolt and inserted, and at the same time, the end of the insertion rod passes through the surface of the second snap plate, so that the snap plate one and the snap plate two are fitted together, and finally the snap plate one and the snap plate two are locked with a lock, thereby locking the operating column at the side end of the fire hydrant, preventing irrelevant personnel from opening the fire hydrant at will, thereby avoiding waste of water resources and water theft.

[0004] However, although this method of locking the snap plate one and the snap plate two with a lock can avoid waste of water resources, if you want to open the fire hydrant, you must have a key, so only relevant personnel have the key.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] See also Figure 1-4A lockable sprinkler fire hydrant, characterized in that it comprises a fire hydrant 1, a docking port 2 is arranged on one side of the lower end of the fire hydrant 1, the docking port 2 is connected to the fire water pipe, a valve 5 is arranged on the top of the fire hydrant 1, the outer ring position of the top of the valve 5 is fixedly connected to one end of the clamping rod 3, the other end of the clamping rod 3 is slidably connected to the upper end of the self-locking structure 4, and the self-locking structure 4 is installed in the groove opened in the fire hydrant 1.

[0026] The self-locking structure 4 includes a locking rod 41, one end of which is slidably connected to the through hole provided in the clamping rod 3, the other end of which is slidably connected to one side of the middle position of the clamping plate 44, the two ends of the clamping plate 44 are rotatably connected to the first locking disk 45, one side of the first locking disk 45 is connected and fixed to one end of the second elastic member 48, the other end of the second elastic member 48 contacts the inner wall of the groove, the other side of the first locking disk 45 is rotatably connected to one side of the second locking disk 46, and the other end of the second locking disk 46 is connected and fixed to the knob 47. A clamping interface 411 is provided at the bottom of the locking rod 41, the clamping interface 411 is slidably connected to the clamping joint 441, the clamping joint 441 is fixedly connected to one side of the middle position of the clamping plate 44, a locking opening 451 is provided on one side of the first locking disk 45, the locking opening 451 is rotatably connected to the convex head 461, the convex head 461 is fixedly connected to the second locking disk 46, and the depth of the locking opening 451 and the clamping interface 411 are the same. When a fire occurs, the knob 47 is turned according to the numbers 1-9 engraved on the outer ring of the knob 47 near the fire hydrant 1, so that the second lock disk 46 and the protrusion 461 are docked with the lock port 451, thereby causing the second elastic member 48 to drive the first lock disk 45 and the card plate 44 to move, and further causing the card joint 441 on the card plate 44 to disengage from the card interface 411, so that the lock rod 41 is not restricted, and finally the first elastic member 42 drives the pressure block 43 to rise, thereby driving the lock rod 41 to rise and disengage from the card disk 49, so that the fire hydrant 1 can be rotated to open.

[0027] A first elastic member 42 is arranged on the outer ring at the upper end of the locking rod 41. The first elastic member 42 may be a spring. The top of the first elastic member 42 is connected and fixed to the bottom of the clamping rod 3. The bottom of the first elastic member 42 is connected and fixed to the top of the pressure block 43. The inner ring of the pressure block 43 is connected and fixed to the outer ring at the middle position of the locking rod 41. The first elastic member can drive the clamping rod 3 to rebound and drive the pressure block 43 to rise, thereby driving the locking rod 41 to rise and disengage from the chuck 49, so that the fire hydrant 1 can be rotated to open.

[0028] The locking rod 41 at the upper end of the pressing block 43 has a square cross section, which can prevent the card interface 411 on the locking rod 41 from rotating and failing to dock.

[0029] The fire hydrant 1 is engraved with numbers 1-9 near the outer ring of the knob 47.

The head of the locking bolt 453 contacts the rotating ring 452. In order to change the password, when the locking rod 41 is separated from the card plate 49, the card plate 49 can be rotated to separate from the fire hydrant 1, and then the locking bolt 453 is loosened by the person rotating it with a wrench, so that the first lock disk 45 can be rotated to change the password.

[0032] The specific operation process of the utility model is as follows: when a fire occurs, the knob 47 is turned according to the numbers 1-9 engraved on the outer ring position of the knob 47 near the fire hydrant 1, so that the second lock disk 46 and the protrusion 461 are docked with the lock port 451, thereby causing the second elastic member 48 to drive the first lock disk 45 and the card plate 44 to move, and further causing the card joint 441 on the card plate 44 to disengage from the card interface 411, so that the lock rod 41 is not restricted, and finally the first elastic member 42 drives the pressure block 43 to rise, thereby driving the lock rod 41 to rise and disengage from the card disk 49, so that the fire hydrant 1 can be rotated to open.

[0033] In order to change the password, when the locking rod 41 is disengaged from the chuck 49, the chuck 49 can be rotated to disengage from the fire hydrant 1, and then the locking bolt 453 is loosened by a person using a wrench to rotate the first lock disk 45 to change the password.
