A quick connector for a concrete grouting pipe used in building construction

Abstract

This utility model proposes a quick-connect coupling for concrete grouting pipes used in building construction, including a bend and ends, with several ends fixedly connected to the end of the bend. The advantages of this utility model are: simultaneous operation of two handles enables quick connection between the connecting pipe and the main pipe, eliminating the need for complex multi-point fastening or bolt fastening methods. Disassembly is achieved simply by rotating the handles in the opposite direction, significantly shortening installation and disassembly time. This immediacy is particularly important for construction sites requiring frequent replacement or adjustment of grouting pipe sections, improving work efficiency. It allows for faster grouting operations, improving overall work efficiency and shortening the construction period. Lifting the handles causes the movable plate to rotate synchronously, with the outer shafts on both sides of the movable plate connecting to the slope of the fastening part until the outer shafts are engaged in the positioning groove of the fastening part. At this point, the fastening ring pulls the boom upwards, and the connecting pipe is tightly inserted into the main pipe port, ensuring the tightness and sealing of the connection between the connecting pipe and the main pipe.
