The application relates to the field of plastic pipe connection, in particular to a reinforced plastic pipe connection structure. The reinforced plastic pipe connection structure comprises a socket pipe fitting and a spigot pipe fitting fixed in the socket pipe fitting; an annular pressure response cavity surrounding the spigot pipe fitting is defined between the inner wall of the socket pipe fitting and the outer wall of the spigot pipe fitting, the spigot pipe fitting is provided with a pressure guide channel communicating with the response cavity; an adaptive locking mechanism is further arranged in the response cavity, the adaptive locking mechanism comprises a driving assembly capable of axially sliding along the socket pipe fitting and a plurality of locking assemblies capable of radially sliding along the socket pipe fitting; a limiting reinforcing sleeve is further fixed outside the socket pipe fitting, the limiting reinforcing sleeve extends to the outside of the spigot pipe fitting and is used for gradually elastically limiting the bending deformation of the spigot pipe fitting. The reinforced plastic pipe connection structure can improve the installation stability and use safety of the conveying pipe.
