Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As illustrated in fig. 1 and 2, a kind of anti-leak sampler, including：Housing unit, the cunning being movably arranged in housing unit
Move component and make slide assemblies that there is the spring 14 of the unidirectional mobile trend of relative housing unit.Housing unit is included from top to bottom
Static seal connects steel ball 15, upper end cover 1, sleeve 3 and the bottom end cover 4 to form internal connection successively.Slide assemblies include slip pipe 5,
Locating part 6 and cock body 7.Upper end cover 1 has the pilot hole for axially extending.Slip pipe 5 is constituted in being slidedly assemblied in pilot hole
Being slidably connected vertically.Locating part 6 is arranged on slip pipe 5 and stretches out on the part of upper end cover 1.Cock body 7 is arranged under slip pipe 5
End.The inwall of bottom end cover 4 has first conical surface 4.1 and bulge loop 4.2 for stopping that cock body 7 is moved up, and bulge loop 4.2 offers some
Inlet opening 4.3.The outer wall of cock body 7 has second conical surface 7.1 that can be engaged with first conical surface 4.1.Spring 14 is arranged on convex
So that second conical surface has the trend for first conical surface separate, energy when slip pipe 5 is slided with respect to housing unit between platform and cock body
