Telecommunication engineering construction fireproof device

The utility model relates to the field of telecommunications engineering, and discloses a telecommunications engineering construction fireproof device, which comprises a telecommunications base; the protective shell is movably connected to the top of the telecommunication base; the fixed part is arranged on the outer wall of the protective shell; and the opening and closing part is arranged in the protective shell. The fixed part comprises an adjusting box which is fixedly connected to one side of the protective shell; and the clamping frame is fixedly connected to the top of the telecommunication base. Through a fixed part and a pressing button, a sliding rod pokes a movable block, so that a shaft rod between the inner walls of the movable block extrudes the sliding block, the sliding block slides along the outer wall of an extrusion column, meanwhile, a second spring is extruded, and when a first spring rebounds and the movable block rotates around a shaft, the second spring drives the sliding block to rebo
