Narrow gap plugging injection device in mechanical and electrical installation

The invention relates to the technical field of installation plugging, in particular to a narrow gap plugging injection device in mechanical and electrical installation, which comprises a tank body with a feed hopper arranged at the top end, the bottom end of the feed hopper penetrates into the tank body, a delivery pump is arranged at the bottom end of the tank body, and a metal hose is arranged on one side of the delivery pump. A plugging pipe is arranged at the other end of the metal hose, and a fixing ring is fixedly connected to the surface of the plugging pipe; the mixing assembly is arranged in the tank body, the labor intensity of the plugging pipe in the plugging process is reduced, and the auxiliary assembly for reducing shaking of the plugging pipe is arranged on the surface of the fixing ring. The device is simple in structure, corresponding gaps can be effectively filled, air in a pipeline and a sleeve can be exhausted, and time and labor are saved during operation. 本发明涉及安装封堵技术领域，具体的说是一种机电安装中狭小缝隙
