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
Skirt jointing generally uses direct insertion structure, and direct insertion structure is fixed by interference fit, still, if magnitude of interference mistake
Big then easily cause installation difficulty, the magnitude of interference is too small, and it is unreliable to cause to fix, particularly when changing the outfit suction tube jointing,
Water in pipe causes very big trouble to installation, and two end connectors of skirt jointing are all normally opens, after end-of-job
When pulling out joint, the liquid that is remained in conduit easily has leakage and brought inconvenience；The joint being fixed on collection device is also required to
Cap just can guarantee that the liquid in device will not be revealed, and installation seems particularly troublesome.
The content of the invention
It is an object of the invention to provide a kind of antidrip suction tube jointing, has quick for installation and connection can
Lean on, have and position auto-lock function in place, the water clock of raffinate in pipeline can be effectively avoided, 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 of bringing inconvenience.
To achieve 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 ends, elastic sealed body, valves
Core and spring；The joint body is sealedly and fixedly connected in fixing end, and 90 ° of interface ends are connected with fixing end rotatory sealing, described
The lower end of fixing end is provided with guide groove A, and valve element includes plunger and led with guide groove A quantity identical guide vanes side, valve element
Guide vane side is slidably matched with guide groove A, and one end and the fixing end of the spring offset, on the other end of spring and guide vane side
Spring card slot offsets, and elastic sealed body includes annular body, and the lower end of annular body has the conical ring upwardly extended；Conical ring
On be provided with fluid through-hole, the lower end of elastic sealed body offsets with intrinsic step, annular body and cone on elastic sealed body
Wing is formed between shape ring and holds liquid bath, the plunger is offseted by the sealing of the fluid through-hole of spring and elastic sealed body.
It is in close shape by Spring driving valve element that the wing of the present invention, which holds liquid bath axis center fluid through-hole in off working state,
State.
As the further scheme of the present invention：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 are inserted into fixing end.Such 90 ° of interface ends, which have, to be rotated about axis
360 ° of the free degree.It can guarantee that any position can jointing.
As the further scheme of the present invention：Guide groove B and locating slot, and guide groove B are provided with the outside of the joint body
Communicated with locating slot.Convenient it can be so attached with interface.
Compared with prior art, beneficial effect of the present invention：This antidrip suction tube jointing, only need to lead in connection
Crossing guide groove A and locating slot very easily docking port can be attached, and cause after fluid is aspirated due to holding liquid bath with wing
Remaining liquid can be back to wing and hold in liquid bath in joint, water clock will not be caused after so taking out joint, for there is pollution
The particularly medical upper recovery with infectious body fluids is very useful, the problem of will not causing secondary pollution.
