Description
Technical field
The invention belongs to medical instruments field, relate to a kind of cryopreservation tube, be specifically related to a kind of improvement structure of cryopreservation tube.
Background technology
Cryopreservation tube is at biology or is medically often used to, for low-temperature storage cell or other material.Cryopreservation tube sealing on market is poor, cause in-built material to be polluted or to reveal, and body easily splits after low temperature.The patent No. is the structure that the Chinese invention patent of CN102845414 discloses a kind of cryopreservation tube on January 2nd, 2013, comprise body, pipe lid, described pipe mounts cover in described body, described pipe lid comprises center circle, surrounding anchor ring, male structure under center, the apical ring structure of the mouth of pipe of described body is flush-mounted in male structure under described center, in the formed annular gap of surrounding anchor ring, the outer ring surface of the described mouth of pipe is connected with the surrounding anchor ring screw threads for fastening of described pipe lid, it makes to be difficult for leaking under long-term ultralow temperature refrigeration, guaranteed that cell is not contaminated, guarantee normally carrying out of subsequent experimental.But also there is its inevitable defect in the structure of this evolute, as: the pollution source of evolute easily touch male structure under Guan Gai center, in pollution source lead-in tube; Evolute because moisture is easily trapped in the screw thread place of pipe lid and body junction, freeze at low temperatures, strengthened the difficulty that pipe lid is turned on, have much room for improvement.
Summary of the invention
The improvement structure that the object of this invention is to provide a kind of cryopreservation tube, its cryovial good airproof performance, is easy to screw operation, and intensity is high, saves material, and cost of manufacture is low.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of improvement structure of cryopreservation tube, comprise body and Guan Gai, being connected with described body of described pipe lid inner-rotary type, described pipe covers and is provided with external screw thread, the mouth of pipe of described body is provided with internal thread, and described internal thread is for establishing each other internal thread segment jaggy or internal thread point.
The present invention adopts the pipe lid of inner-rotary type, has solved outward turning easy-to-leak liquid, the defect that pad easily falls, better tightness; If adopt traditional inside spin structure, when the pouring out of liquid feeding or liquid in pipe in pipe, have certain inhibition, cause liquid in pipe to have residual, impact operation and accuracy, and the internal thread of the mouth of pipe adopts segmentation or dot structure, can not affect pouring out to liquid feeding in pipe or liquid in pipe.
As preferably, described pipe lid is cylindric, by top to bottom, comprises that hand twists portion and connecting portion, and the external diameter that described hand is twisted portion is greater than the internal diameter of described connecting portion, twists the formation convergence part, junction of portion and described connecting portion at described hand.
As preferably, described convergence part is provided with sign sealing ring, and the internal diameter of described sign sealing ring is greater than the external diameter of described connecting portion, and the internal diameter of described sign sealing ring is more than or equal to the external diameter that described hand is twisted portion.
Sign sealing ring is set, can plays sealing function, guarantee the sealing of cryopreservation tube, by the sealing ring of different colours is set, can also play mark action simultaneously, easy to use, need not specially remove to arrange mark again, save cost and technique.
As preferably, below described sign sealing ring, be provided with auxiliary seal ring, the internal diameter of described auxiliary seal ring is identical with described sign sealing ring, and external diameter is greater than the external diameter of described sign sealing ring.
Because cryovial is usually to take out from low temperature, sign sealing ring can be adhered to mouth of pipe place, is turning on pipe while cover, indicates that sealing ring can be driven, repeatedly, affect its sealing function, auxiliary seal ring is set, double shield, and when twisting the lid off, finger props up sealing ring to the hand portion of twisting, prevent from being driven, auxiliary seal ring external diameter is greater than described sign sealing ring, conveniently props up action.
As preferably, between the upper surface of described externally threaded top one circle and the lower surface of the stubborn portion of described hand, form seal groove, described sealing ring is arranged in described seal groove.Can enhanced leaktightness circle fixing, the service life that strengthens sealing ring.
As preferably, the width of described seal groove equals the thickness sum of described sign sealing ring and described auxiliary seal ring, can block sealing ring by seal groove, and preventing, because turning on of pipe lid moves up and down it, affects its intensity and sealing.
As preferably, described hand twists portion and described connecting portion is cylindrical-shaped structure empty in one, and the bottom of described connecting portion is provided with end face.
The cylindrical-shaped structure of interior sky can be saved material, reduces costs, and the setting of the bottom end face of connecting portion, sealed tube body, also prevents from managing interior material and enters in pipe lid, causes waste or pollutes.
As preferably, in the cylindric interior sky of the stubborn portion of described hand, be provided with the reinforcement that connects circumference.
Because cryovial is usually to take out from low temperature, turn on pipe while cover, need certain dynamics, if power is excessive or the service time of cryopreservation tube is longer, the pipe of interior sky lid is easily bad, and the intensity that reinforcement can reinforced pipe covers is set, and extends its service life.
As preferably, described reinforcement vertically arranges, and through the center of circle of place, described cylindrical cross section circle, reinforced pipe lid intensity effect is better.
By implementing technique scheme, the present invention has following beneficial effect: cryopreservation tube good sealing effect provided by the invention, do not affect pouring out of the interior material of pipe, and be easy to screw operation, intensity is high, has group indication function, saves material, and cost of manufacture is low.
