Technical Field

The utility model relates to the technical field of pipe fittings, in particular to an embedded quick pipe inserting joint.

Background

The air pipe joint is a part applied in industrial production, medical industry and various industries, the common joint has various varieties, joints with different structures are generally selected according to different application areas, for example, dozens or hundreds of air joints are externally connected on a main air pipe of a production line, a conventional main air pipe is arranged at the upper end of the production line, a working air pipe with a quick connector at the connecting end is connected to the air joint externally connected with the main air pipe to supply air to a starting tool, however, the air joint externally connected on the main air pipe on the production line is generally a straight cylinder type quick connector female part with a conventional structure and is limited by the application environment, and once the matching property is modified according to the change of the application environment, the phenomenon of poor sealing property exists. Therefore, the air pipe joint in the related art has the defects of low adaptability and poor sealing performance.

Therefore, there is a need to provide a new quick connect coupling for a male cannula that solves the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the technical problems and provide an embedded quick cannula joint with higher adaptability and better sealing property.

The utility model provides an embedded quick-insertion pipe joint, which comprises a pipe joint body, a fixed sleeve, an elastic sheet, a supporting seat, a sealing ring, a lining core, a check ring and a locking ring, wherein the fixed sleeve, the elastic sheet, the supporting seat, the sealing ring, the lining core, the check ring and the locking ring are fixed on the pipe joint body, the elastic sheet supports against the fixed sleeve and is accommodated in the supporting seat, the supporting seat simultaneously supports against the fixed sleeve, the sealing rings comprise a first sealing ring, a second sealing ring and a third sealing ring, the first sealing ring is sleeved in the pipe joint body and clamped between the lining core and the inner wall surface of the pipe joint body, the second sealing ring and the third sealing ring are sleeved and fixed outside the pipe joint body, the lining core is sleeved and fixed in the pipe joint body and sequentially penetrates through the fixed sleeve, the elastic sheet and the supporting seat, the check ring and the locking ring are sleeved and fixed outside the pipe joint body, and the check ring is clamped between the pipe joint body and the locking ring.

Preferably, the sealing ring is an O-ring.

Preferably, the elastic sheet is a quincuncial elastic sheet.

Preferably, the pipe joint further includes a cap covering the second sealing ring and the third sealing ring.

Preferably, the retainer ring is a plum blossom retainer ring.

Preferably, the pipe joint further includes a loosening cap covering the core and inserted into the pipe joint body.

Preferably, the retainer ring and the lock ring are both located between the second seal ring and the third seal ring.

Compared with the prior art, the embedded quick insertion pipe joint has higher adaptability and better sealing property.
