Flow-controllable indoor fire hydrant

The flow-controllable indoor fire hydrant comprises an indoor fire hydrant shell installed in an indoor wall, a first connecting part connected with a water supply end is formed at the bottom of the indoor fire hydrant shell, and a second connecting part connected with output is formed on the indoor fire hydrant shell; a first communicating channel is arranged between the first connecting part and the second connecting part, the flow control block is movably connected to the first communicating channel, and the cross section of the flow control block is sequentially or intermittently reduced from top to the cross section of the first communicating channel. A certain angle is formed between the second connecting rod and the first connecting rod, switching and flow regulation control of an indoor fire hydrant installed in a wall can be facilitated, the second connecting rod and the first fixing block are connected through the damping connecting shaft, and therefore rotation limiting can be achieved, the size of
