Description
Technical field
What the present invention relates to is a kind of two-way sealing pull-off resisting plug-in type rapid joint, is applicable to make air and liquid transmission pipeline connected element.
Background technique
At present, air and liquid transmission pipeline jointing easy to leak easily come off, and pipeline circularity is required height, and it is convenient inadequately to install and use.
Summary of the invention
The present invention seeks at above-mentioned deficiency, a kind of two-way sealing pull-off resisting plug-in type rapid joint is provided, comprise joint body, locking nut, elastic pawl, tube stay and O RunddichtringO, owing to there is tube stay to hold round pipeline outer wall, the O RunddichtringO is subjected to end face and the extruding of side bi-directional secondary, can be to carrying out reliable sealing between pipeline and the joint body; Because the metal pallets of elastic pawl inboard can be thrust pipeline outer wall, reach the purpose that pipeline locking resistance to plucking takes off simultaneously.Because the joint body upper locking nut can be pre-installed, and can quickly and easily pipeline directly be inserted joint body, realize inserting the purpose of fast-assembling.
Two-way sealing pull-off resisting plug-in type rapid joint takes following scheme to realize: two-way sealing pull-off resisting plug-in type rapid joint comprises joint body, locking nut, elastic pawl and O RunddichtringO.Joint body hollow, be provided with the body connecting port at joint body one end, be provided with the locking outside thread in outside, body connecting port, on the locking outside thread, locking nut is housed, in the body connecting port, elastic pawl is housed, between elastic pawl and inside, body connecting port, the O RunddichtringO is housed.Elastic pawl has the elastic pawl body, and the elastic pawl body is provided with several elastic claws, has notch between the elastic claw, and the preceding outer end of elastic claw is provided with tilted conical surface, and elastic pawl body hollow is equipped with the metal thorn claw in the elastic claw inboard.The metal thorn claw can be provided with the 2-8 sheet, determines according to connecting the body size.Locking nut hollow, the front end inboard is provided with conical surface, and its conical surface matches with the elastic claw outer end tilted conical surface of elastic pawl.Body disposes tube stay in the connecting port.
Two-way sealing pull-off resisting plug-in type rapid joint, unclamp locking nut during use, loosen elastic pawl, the pipe end portion that need are connected inserts tube stay, again pipeline is inserted in the body connecting port of joint body, pass the O RunddichtringO, then locking nut is locked, when pipeline passed the O RunddichtringO, the O RunddichtringO produced lateral compression, formed pipeline and joint body lateral seal, lock locking nut simultaneously, the conical surface promotion elastic pawl of locking nut front end inboard moves backward and pushes the O RunddichtringO, makes the O RunddichtringO form the sealing of end face direction once more between joint body and pipeline, reaches the two-way effect of sealing once more.The proal while of elastic pawl, the outside tilted conical surface of the conical surface of locking nut front end inboard extrusion elastic claw, inwardly the compressed metal ratchet thrusts pipeline outer wall, thereby reaches locking pipe, prevent the purpose that pipeline comes off.
When needing dismounting locking nut is unclamped, elastic pawl unclamps simultaneously, and the metal thorn claw of elastic claw inboard unclamps from pipeline outer wall, promptly pipeline conveniently can be extracted from joint body.
Two-way sealing pull-off resisting plug-in type rapid joint is reasonable in design, compact structure.Owing to there is tube stay to hold round pipeline outer wall, the O RunddichtringO is subjected to end face and the extruding of side bi-directional secondary, can be to carrying out reliable sealing between pipeline and the joint body; Because the metal pallets of elastic pawl inboard can be thrust pipeline outer wall, reach the purpose that pipeline locking resistance to plucking takes off simultaneously.Because the joint body upper locking nut can be pre-installed, and can quickly and easily pipeline directly be inserted joint body, realize inserting the purpose of fast-assembling.
