[0015] The present application embodiment discloses a fire hydrant for fire engineering that is easy to connect, referring to Figure 1 , Figure 2 and Figure 3, including a fire hydrant body 1 and a base 2, the base 2 is located at the bottom of the fire hydrant body 1, a connecting ring 31 is welded on the top of the base 2, and the connecting ring 31 is communicated with the base 2, an outer wall of the connecting ring 31 is provided with an external thread, a mounting ring 32 is welded on the bottom end of the fire hydrant body 1, and the mounting ring 32 is communicated with the fire hydrant body 1, an inner wall of the mounting ring 32 is provided with an internal thread, the external thread provided on the outer wall of the connecting ring 31 is matched with the internal thread provided on the inner wall of the mounting ring 32, the mounting ring 32 is threadedly sleeved on the outer surface of the connecting ring 31, and an outer octagonal rotating ring 33 is fixedly sleeved on the outer surface of the mounting ring 31, by placing the fire hydrant body 1 on the top of the base 2, and making the mounting ring 32 located directly above the connecting ring 31 and in contact with the connecting ring 31, then rotating the outer octagonal rotating ring 33 to drive the mounting ring 32 to rotate, so that the mounting ring 32 can be threadedly sleeved on the outer surface of the connecting ring 31, thereby completing the connection between the mounting ring 32 and the connecting ring 31, so that the fire hydrant body 1 can be installed on the base 2.

[0016] Reference Figure 2 and Figure 3 The fire hydrant body 1 is composed of a fire hydrant body 11, a water outlet pipe 12 and a sealing cover 13. There are two water outlet pipes 12 and two sealing covers 13. The two water outlet pipes 12 are connected to the fire hydrant body 11. The two water outlet pipes 12 can discharge water from the fire hydrant body 11. The outer walls of one end of the two water outlet pipes 12 are provided with external threads, and the inner walls of the two sealing covers 13 are provided with internal threads. The external threads provided on the outer walls of one end of the two water outlet pipes 12 are adapted to the internal threads provided on the inner walls of the two sealing covers 13. The two sealing covers 13 are respectively threadedly sleeved on the outer surfaces of the two water outlet pipes 12. A hexagonal block 14 is welded to one side of the sealing cover 13. By using an external wrench to rotate the two hexagonal blocks 14 to drive the two sealing covers 13 to rotate, the two sealing covers 13 are respectively threadedly sleeved on one end of the two water outlet pipes 12, so as to achieve the purpose of blocking the two water outlet pipes 12. After the two sealing covers 13 are threadedly disengaged from the two water outlet pipes 12, one end of the external fire hose is stuck inside the two water outlet pipes 12, so that the water in the external fire-fighting pipeline can be transported to the inside of the fire hose through the fire hydrant body 11 and the water outlet pipe 12, and then discharged from the fire hose for fire extinguishing.
