Abstract
This invention relates to the field of pipe joint technology, specifically a quick connector for concrete pumping pipes, comprising a first connector, a second connector, a limiting post, and a sleeve. The first connector has an annular limiting groove, and the second connector has a moving groove pointing towards its axis. A receiving groove is formed at the top of the moving groove, with a cross-sectional area larger than that of the moving groove. The limiting post matches the shape of the moving groove, and a limiting block is formed at the top of the limiting post. The cross-sectional shape of the limiting block matches that of the receiving groove, and the height of the limiting block is less than the height of the receiving groove. The limiting post and the limiting groove attract each other, and the sleeve attracts the limiting post. The sleeve is fitted over the second connector, enabling quick connection of the pumping pipe. The connection has high strength, is not easily separated, and is not easily affected by solidified concrete, avoiding the problem of inability to quickly connect due to adhering concrete. This design has practical significance and promotional value.
