Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-4, the pipeline connection structure comprises a plug 1 and a socket 5, wherein the plug 1 is slidably inserted into the socket 5, a spring 4 is installed between the plug 1 and the socket 5, U-shaped grooves 6 are further formed in two sides of a top end opening of the socket 5, connecting pins 2 are arranged on two sides of the plug 1 and correspond to the U-shaped grooves 6, the connecting pins 2 are clamped in the U-shaped grooves 6, and the connecting pins 2 located in the U-shaped grooves 6 are limited and check through check clamping rods 7.

The plug 1 is T-shaped, the extrusion part 11 of the plug 1 is in extrusion contact with the spring 4, the plug 1 is in sliding fit with the inner cavity of the socket 5, and the plug 1 is sleeved with the sealing ring 3 and is in sealing connection with the inner cavity of the socket 5.

Wherein, U type groove 6 includes vertical push down, lift channel 61, horizontal rotatory passageway 62 and the spacing groove 63 of opposite side in proper order, and connecting pin 2 card is established in spacing groove 63 department, is located and rotates on the socket 5 outer wall directly over the spacing groove 63 and installs non return clamping lever 7, and non return clamping lever 7 is the T type of handstand.

Wherein, when the check clamping rod 7 rotates to vertical, the vertical portion of the check clamping rod 7 is embedded in the connecting pin 2, the horizontal portion of the check clamping rod 7 is contacted with the bottom of the connecting pin 2, and the vertical groove is formed in the middle of the tail end of the connecting pin 2, and the groove is matched with the vertical portion of the check clamping rod 7.

In this embodiment, during installation, only need with plug 1, connecting pin 2 push in socket 5 along U type groove 6 direction, connecting pin 2 pushes down along pushing down, lift channel 61 is down, plug 1 bottom extrusion spring 4, anticlockwise rotatory connecting pin 2 moves to spacing groove 63 department in rotatory passageway 62 again, after plug 1 loosens, connecting pin 2 card goes into spacing groove 63, inlay the vertical portion that vertical back card pole 7 was rotated to check card pole 7 in connecting pin 2, the horizontal part of check card pole 7 and the bottom contact of connecting pin 2, and sealing washer 3 on plug 1 and socket 5's inner chamber form sealedly, accomplish the erection joint promptly, not only the leakproofness is good, moreover can lock plug 1 for plug 1 and socket 5 stable connection.
