Preferably, being provided with the gear handle for rotating inner cylinder on the inner cylinder, turned by keeping off what be can be convenient Dynamic inner cylinder, operates more convenient laborsaving.

Preferably, be arranged on the outer barrel it is jagged, the gear can along notch left-right rotation, structure is simple, It is easy to process.

Preferably, the sample tap on sample tap and outer barrel when the gear is notch right end is in, on inner cylinder Alignment, sample tap is open state at this time；The gear is sample tap when turning to left end from notch right end, on inner cylinder It is staggered completely with the sample tap on outer barrel, sample tap is closed state at this time.Structure is simple, low manufacture cost, can be a wide range of It promotes and applies.

Preferably, the outer barrel is the stainless steel tube of overall length 600mm, diameter 62mm, the inner cylinder is overall length The stainless steel tube of 500mm, diameter 60mm.Material is cheap and easily-available, and durable, low manufacture cost, guarantees service life.

Preferably, the notch is the semicircular opening that width is 10mm, structure is simple, easy to process.

Preferably, being provided with annular shoulder block on the outer barrel, play the role of support limit in sampling.

The beneficial effects of the utility model are: rotation airtight sampler described in the utility model, sample tap can be closed, When taking out sampler, in sample will not wherein device be lost from sampling, sample completely be retained, and alleviate operator's Labor intensity greatly improves work efficiency；And, it is ensured that sample will not be sucked by operator, realize safety operation, be protected Hinder the health of operator, meets the control to product quality sampling accuracy in production.Rotation described in the utility model Turn airtight sampler, structure is simple, and easy to process, low manufacture cost can be applicable on a large scale.
