Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, how to implement the present invention is further explained below with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 to 6, an embodiment of the detachable socket anti-disengaging structure for a drainage pipeline of the present invention includes a socket joint 1 and a socket joint 2, which are in socket fit with each other and are respectively disposed on two drainage pipelines butted with each other; specifically, two anti-falling buckles 11 are arranged on the bellmouth joint 1, and the two anti-falling buckles 11 are symmetrically arranged on two sides of one end, close to the socket joint 2, of the bellmouth joint 1; two annular protruding stop ribs 21 and three annular sealing grooves 22 are arranged on the socket joint 2, the two annular protruding stop ribs 21 are arranged at the end, far away from the socket joint 1, of the socket joint 2 at intervals, and the three annular sealing grooves 22 are arranged at the end, close to the socket joint 1, of the socket joint 2 at intervals. Each annular raised stop rib 21 arranged on the socket joint 2 is used for stopping and matching with two anti-falling buckles 11 arranged on the socket joint 1, so that the socket joint 2 only can move forward and cannot move backward when being inserted into the socket joint 1, and the socket joint has an anti-falling function while realizing water-closing connection between two adjacent drainage pipelines 4; a sealing rubber ring 3 which is used for being matched with the annular sealing groove 22 is arranged in each annular sealing groove 22 arranged on the socket joint 2, and each sealing rubber ring 3 is used for realizing the sealing connection between the socket joint 2 and the socket joint 1 when the socket joint 2 is inserted into the socket joint 1.
