Description

Pipeline connection injection molding socket Technical Field The utility model relates to the field of pipeline connection structures, in particular to a pipeline connection injection molding socket. Background For corrugated pipes and straight-wall pipes, the corrugated pipes are widely applied to the fields of water delivery systems, sewage disposal systems, municipal drainage and the like. When laying a plurality of pipes, a connecting structure is required to connect any two adjacent straight pipes (two corrugated pipes or two straight-wall pipes) so as to assemble a complete pipe with a required length. The existing straight pipe can be connected through a sleeve structure, and the split sleeve joint comprises an outer sleeve and an inner sleeve which are connected in a socket-joint mode, the connection firmness between the outer sleeve and the inner sleeve is low, dislocation is easy to generate, and leakage is caused. Disclosure of utility model The utility model aims to solve the problems in the background art, and provides a pipeline connection injection molding socket plug, which is used for carrying out anti-drop limit on socket connection between an outer sleeve and an inner sleeve through a limit structure and sealing through a rubber ring, so that the connection firmness and the tightness are ensured, and leakage is not easy to occur. The technical scheme includes that the pipeline connection injection molding socket comprises an outer sleeve and an inner sleeve, wherein one end of the outer sleeve is provided with a socket part, one end of the inner sleeve is provided with a socket part inserted into the inner side of the socket part, and the socket part is in limiting connection with the socket part through a limiting structure and is in sealing connection with the socket part through a rubber ring. Preferably, the first rubber ring is positioned between the limiting structure and the outer end of the socket part. Preferably, the other end of the outer sleeve and the other end of the inner sleeve each have a cannula portion. Preferably, the outer diameter and the inner diameter of both cannula parts are equal. Preferably, the inner peripheral surface of the bell mouth part is provided with a first groove for clamping the rubber ring I, the outer peripheral surface of the spigot mouth part is provided with a second groove for clamping the rubber ring I, and the first groove and the second groove are annular grooves. Preferably, the socket part is provided with a convex limiting ring part, the limiting ring part gradually inclines outwards along the direction from one end of the inner side of the socket part to one end of the outer side of the socket part, a clamping groove is formed in the inner side of the socket part, a plurality of notches are formed in the periphery of the socket part and correspond to the buckle plate part which can be clamped at the clamping groove, the inclination direction of the buckle plate part is the same as that of the limiting ring part, and the limiting ring part and the buckle plate part form a limiting structure. Preferably, the inner peripheral surface of the socket part is provided with a first buckling part protruding inwards, the outer peripheral surface of the socket part is provided with a second buckling part protruding outwards, and the first buckling part is in buckling connection with the second buckling part and forms a limiting structure. Preferably, the outer sleeve is provided with a plurality of reinforcing ribs at its outer periphery.
