Description
Technical field
The present invention relates to suction tube jointing equipment technical field, especially a kind of antidrip suction tube jointing.
Background technology
Suction tube jointing is widely used in daily life and industrial production it may be said that ubiquitous, traditional suction
The commonly used direct insertion structure of skirt jointing, direct insertion structure relies on interference fit to fix, but, if magnitude of interference mistake
Big then easily cause installation difficulty, the magnitude of interference is too little, causes fixation unreliable, particularly when changing the outfit suction tube jointing,
Water in pipe causes very big trouble to installing, and two end connectors of skirt jointing are all normally opens, after end-of-job
When pulling out joint, in conduit, the liquid of residual easily has leakage and brings inconvenience；The joint being fixed on collection device is also required to
Liquid in cap guarantee device will not be revealed, and install and seem particularly troublesome.
Content of the invention
It is an object of the invention to provide a kind of antidrip suction tube jointing, have quick for installation and connect can
Lean on, there is positioning auto-lock function in place, can effectively avoid the water clock of raffinate in pipeline, to solve to propose in above-mentioned background technology
Installation difficulty, the stationarity of installation is unreliable, and the liquid in conduit easily reveals the problem bringing inconvenience.
For achieving the above object, the present invention provides following technical scheme：
A kind of antidrip suction tube jointing, including joint body, fixing end, 90 ° of interface end, elastic sealed body, valve element and
Spring；Described joint body is sealedly and fixedly connected in fixing end, and 90 ° of interface end are connected with fixing end rotatory sealing, described fixation
End lower end be provided with gathering sill, valve element include plunger and with gathering sill quantity identical guide vane side, the guide vane side of valve element
It is slidably matched with gathering sill, one end of described spring and fixing end offset, the Spring Card on the other end of spring and guide vane side
Groove offsets, and elastic sealed body includes annular body, and the lower end of annular body has upwardly extending conical ring；Have on conical ring
Fluid through-hole, the lower end of elastic sealed body is offseted with intrinsic step, the annular body on elastic sealed body and conical ring it
Between form wing and hold liquid bath, the fluid through-hole that described plunger passes through spring and elastic sealed body seals and offsets.
It is in close shape by Spring driving valve element that the wing of the present invention holds liquid bath axle core flow through hole in off working state
State.
As the further scheme of the present invention：Described 90 ° of interface end external diameters have annular boss, and fixing end internal diameter also has
Ring-type positive stop lug boss, the interface end with annular boss section is inserted in fixing end.Such 90 ° of interface end have and are rotated about axis
360 ° of the free degree.Can guarantee that any position can jointing.
As the further scheme of the present invention：Have gathering sill and locating slot outside described joint body, and gathering sill with
Locating slot communicates.So can convenient be attached with interface.
Compared with prior art, beneficial effect of the present invention：This antidrip suction tube jointing, only needs to lead to when connecting
Cross gathering sill and locating slot can very easily docking port be attached, after suction fluid, hold liquid bath so that connecing due to having wing
In head, remaining liquid can be back to wing and hold in liquid bath, does not result in water clock after so taking out joint, special for there being pollution
Be not have on medical infectious body fluids recovery very useful, do not result in the problem of secondary pollution.
