[0003] When the fire hose is used up, it is generally necessary to drain the water in the fire hose before the fire hose can be reeled in. However, when reeling in a general fire hose, firefighters are required to drain the water in the fire hose before reeling it in. However, since the fire hose is relatively long, it is also a waste of firefighters' time when draining the water. Utility Model Content

However, when reeling in a general fire hose, the firefighters are required to drain the water in the fire hose before the fire hose can be reeled in. However, since the fire hoses are relatively long, it takes a lot of time for the firefighters to drain the water.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a safety fire hydrant for fire fighting, comprising a fire box, a fire hydrant body is installed at the bottom of the fire box, a first interface is opened on one side end surface of the fire hydrant body, a valve handle is arranged at the top of the fire hydrant, a plurality of raised blocks in a circular array are fixedly installed on the valve handle, a first pressure roller is arranged on the inner wall of the fire box closer to the right side, a second pressure roller is arranged on the left side of the first pressure roller, a connecting column is fixedly installed on the inner wall of the fire box body closer to the upper end, and a winding disk is arranged on the connecting sleeve.
[0006] By adopting the above technical scheme, the fire hydrant body is protected by a fire hydrant box, and then the first interface opened on one end face of the fire hydrant body can be connected to the second interface on the water hose to facilitate water supply, and then the valve handle on the top of the fire hydrant body is rotated to open the valve in the fire hydrant body. Because a plurality of raised blocks are installed on the surface of the valve handle, the operator can better open the valve without slipping, and then the connecting column installed in the fire hydrant box facilitates the rotation of the reel.
[0007] Preferably, a winding roller is fixedly mounted on the front end surface of the winding disk, a cross-shaped slot is provided on the front end inner wall of the winding roller, and a fire hose is wound on the winding roller.
[0008] By adopting the above technical solution, the fire hose is wound up by means of a winding roller installed on the surface of the winding disk, and then the card slot provided in the winding roller facilitates engagement and disassembly with the limit plate.
[0009] Preferably, a second interface is provided at one side end of the fire hose, and a water outlet gun is fixedly installed at the water outlet end of the fire hose.
[0010] By adopting the above technical solution, the second interface provided on one end face of the fire hose can be connected to the first interface provided on the fire hydrant body, and then the water outlet gun fixedly installed at the water outlet end of the fire hose can discharge water from the water outlet end.
[0011] Preferably, a limit plate is inserted into the slot opened at the inner end of the winding roller, and a block is fixedly installed on the inner end face of the limit plate. The shape of the block is a cross and the size of the block matches the size of the slot. A rotating handle is provided on the front end surface of the limit plate.
[0012] By adopting the above technical solution, the limit plate and the reel are fixed to each other due to the cooperation between the clamping block and the clamping slot. At the same time, the reel is mounted on the connecting column, so that the reel can be rotated by turning the handle to reel in order to reel up the fire hose.
[0013] Preferably, a fire box door is movably mounted on the front end surface of the fire box, a door handle is fixedly mounted on the front end surface of the fire box door, and a positioning hole is provided on the right end surface of the fire box door.
[0014] By adopting the above technical solution, the fire box door installed at the front end of the fire box can be opened to use the fire-fighting facilities in the fire box, and then the positioning hole opened at the right end of the fire box door facilitates the insertion rod to limit the fire box door.
[0015] Preferably, an insertion rod is inserted into the right end face of the fire extinguisher box, and the insertion rod passes through the right end face of the fire extinguisher box and is inserted into a positioning hole opened at the right end of the fire extinguisher box door. A connecting plate is fixedly installed on the outer end of the insertion rod, and a spring is fixedly installed on the inner end face of the connecting plate. The other end of the spring is fixedly installed on the right surface of the fire extinguisher box, and a pull ring is fixedly installed on the outer surface of the connecting plate. An observation window is opened on the front end surface of the fire extinguisher box, and the material used for the observation window is a hard PVC transparent plastic plate.
[0016] By adopting the above technical solution, by pulling the pull ring outward, and because the pull ring is installed on the mounting plate, when the pull ring is pulled, the spring has a certain elastic force and can be stretched well, so that the plug rod is pulled out from the positioning hole opened on the right end face of the fire box door, thereby canceling the fixation of the fire box door, and then because the observation window set at the front end of the fire box door is made of hard PVC transparent plastic plate, compared with traditional glass observation windows, the hard PVC transparent plastic plate has high hardness and transparency, and is not easy to deform, so it will not break.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] 1. A fire-fighting safety fire hydrant. When the fire hose is rolled up, the fire hose is placed between the first pressing roller and the second pressing roller. Since the gap between the first pressing roller and the second pressing roller is small, the water in the fire hose can be squeezed out better, so that the residual water in the fire hose can be discharged from the water outlet nozzle, so that the fire hose can be rolled up faster, effectively saving the time of firefighters.
[0019] 2. This fire-fighting safety fire hydrant is operated by pulling the pull ring outward. Since the pull ring is installed on the mounting plate, the spring has a certain elastic force when the pull ring is pulled and can be stretched well, so that the plug rod can be pulled out of the positioning hole opened on the right end face of the fire box door, thereby canceling the fixation of the fire box door, and then the fire box door is opened by pulling the door handle to use the fire hydrant in the fire box.

[0030] Working principle: when it is necessary to use a fire hydrant, first remove the fire hose 12, and then align the second interface 13 on the fire hose 12 with the first interface 3 of the fire hydrant body 2. After the first interface 3 and the second interface 13 are installed, turn the valve handle 4 at the top of the fire hydrant body 2 to open the valve in the fire hydrant body 2. Because the surface of the valve handle 4 is equipped with a plurality of protrusions 5, the operator can better open the valve without slipping. Then, when the fire hydrant body 2 is opened, the water will be discharged from the water nozzle 14 at the other end of the fire hose 12. Then, when the operator has completed extinguishing the fire, it is generally necessary to squeeze out the water in the fire hose 12 and then reel the fire hose 12. Therefore, first install the reel 9 into the connecting column 8, and then align the block 16 installed on the inner end surface of the limit plate 15 to the reel.
