In order to achieve the purpose, the invention provides the following technical scheme:

the utility model provides a pipeline connection's structure of inserting soon, includes fast socket and connector, fast socket sets up on first hard tube, the connector sets up on the second hard tube, fast socket is cylindrical flaring structure, the connector is cylindrical through structure, first hard tube is connected with the second hard tube through fast socket and connector, spacing recess has been seted up on the lateral wall of connector, be provided with the sealing washer in the spacing recess, be provided with spacing draw-in groove on the lateral wall of fast socket, the joint has the spring card in the spacing draw-in groove.

Preferably, the quick socket seat and the first hard pipe as well as the connector and the second hard pipe are of an integrated structure.

Preferably, the number of the limiting grooves is two, and each limiting groove is internally provided with a sealing ring.

Preferably, the sealing ring is an O-shaped sealing ring, and the section of the sealing ring is circular.

Preferably, the inner side wall of the quick socket is in interference fit with the sealing ring.

Preferably, the inner side of the quick insertion tube seat is provided with a first limiting boss, and the connector abuts against the first limiting boss.

Preferably, a second limiting boss is arranged on the outer side wall of the connector.

Compared with the prior art, the invention has the beneficial effects that:

the quick assembly disassembly can be realized through the cooperation of fast socket, connector, spacing draw-in groove and spring card, can guarantee good leakproofness through the sealing washer in the spacing recess. This insert structure soon can be convenient for the pipeline dismouting, improves assembly efficiency, practices thrift and arranges the space, simple structure simultaneously, reduce cost.
