Fig. 3 is the structural schematic diagram of the utility model middle tube body.
Specific embodiment
The utility model is described in further detail combined with specific embodiments below.
The cryopreservation tube with protective device, including outer protection cap 1, inner cover 2, ferrule pressure pad 3 and tube body 4；It protects outside
The outer wall lower end of protecting cover 1 is equipped with outer protection cap external screw thread 1.1, is fixed with gasket mounting ring in the inner wall integral middle of inner cover 2
2.2, ferrule pressure pad 3 is integrally fixed in gasket mounting ring 2.2, the inner cover 2 above gasket mounting ring 2.2
Inner wall is equipped with the first inner cover internal screw thread 2.1, and the inner wall of the inner cover 2 below gasket mounting ring 2.2 is equipped in the second inner cover
The inner wall of screw thread 2.3, the inner cover 2 below the second inner cover internal screw thread 2.3 is equipped with inner cover handle ratchet wheel 2.4, in corresponding nozzle position
The outer wall of tube body 4 be equipped with tube body external screw thread 4.1, be equipped with outside tube body on the outer wall of the tube body 4 below tube body external screw thread 4.1
Ratchet 4.2；
Cooperated by the first inner cover internal screw thread 2.1 with outer protection cap external screw thread 1.1, outer protection cap 1 is screwed with inner cover 2；It is logical
It crosses tube body external screw thread 4.1 and the second inner cover internal screw thread 2.3 cooperates, tube body 4 is screwed with inner cover 2；By ratchet 4.2 outside tube body with it is interior
Lid handle ratchet wheel 2.4 cooperates, tube body 4 and 2 one-way locking of inner cover；Ferrule pressure pad 3 is pressed on tube body by gasket mounting ring 2.2
4 nozzle.
The outer protection cap 1 is between outer land stage structure, and the upper section outer diameter of outer protection cap 1 is greater than the lower section outer diameter of outer protection cap 1,
The outer protection cap external screw thread 1.1 is equipped in the lower section outer wall of outer protection cap 1.
The outer cover antislip cog 1.2 of setting in a vertical shape is equipped in the upper section outer circle of outer protection cap 1.
The inner cover antislip cog 2.5 of setting in a vertical shape is equipped in the outer circle of the inner cover 2.
Inner cover 2 and the ferrule pressure pad 3 of silica gel material use Double-color integrated injection molding, pass through spiral shell in the second inner cover
Line 2.3 and tube body external screw thread 4.1, inner cover 2 is tightened on tube body 4, while ferrule pressure pad 3 is also by gasket mounting ring 2.2
It is pressed on above the nozzle of tube body 4, plays the role of sealing.
By outer protection cap external screw thread 1.1 and the first inner cover internal screw thread 2.1, outer protection cap 1 can screw in inner cover 2, make outer
Protection cap 1 plays sealing function to inner cover 2, in this way, can also screw on outer protection again after ferrule pressure pad 3 is pierced
Lid 1 guarantees the leakproofness of this cryopreservation tube.
The inner wall of inner cover 2 below the second inner cover internal screw thread 2.3 is equipped with inner cover handle ratchet wheel 2.4, in tube body external screw thread 4.1
The outer wall of the tube body 4 of lower section is equipped with the outer ratchet 4.2 of tube body, when so that inner cover 2 being tightened in the clockwise direction, inner cover handle ratchet wheel
2.4 can enter the outer ratchet 4.2 of tube body, and when inner cover 2 needs counterclockwise to unscrew, due to inner cover handle ratchet wheel 2.4 and tube body outside
The locking of ratchet 4.2 and can not unscrew.
The working principle of the utility model is as follows:
After the sample that need to be stored is put into tube body 4, inner cover 2 is screwed on, ferrule pressure pad 3 is moulded in inner cover 2
Molding together, that is, screwing on inner cover 2, ferrule pressure pad 3 also seals the nozzle compression of tube body 4 simultaneously, after inner cover 2 screws,
Inner cover handle ratchet wheel 2.4 and the outer ratchet 4.2 of tube body of tube body 4 on inner cover 2 are mutually twisted, and cannot reversely be unscrewed, be played locking again
De- effect.Outer protection cap 1 is spun on inner cover 2 again, for protecting nozzle sealed pressure pad 3.When sampling, outer protection is first opened
Lid 1, inner cover 2 are needed at this time with sampling probe since the effect of ratchet mechanism cannot open by the ferrule pressure pad 3 in inner cover 2
Medium position puncture is sampled, and after ferrule pressure pad 3 is pierced, is no longer sealed, outer protection cap 1 can be spun on inner cover 2
On, sample can continue to save, while ferrule pressure pad 3 be pierced after this sample can be prompted whether intact or be drawn
It crosses.
