Chinese utility model patent discloses a kind of novel stem cells cryopreservation tube, notification number is 203353518U, it arranges external screw thread at the outer side-lower of the tube mouth of cryopreservation tube, bottom arranges spill base, pipe lid bottom inside arranges internal thread, body bottom pipe lid is fixed body seal protection ring, its cooperation by internal and external threads and seal protection ring stop bacterium and biological entering, but this kind of device needs to reequip cryopreservation tube, and cryopreservation tube is once other devices that damage and cryopreservation tube install additional also can not use, and it can only play the sealing on definite meaning by threaded closure, its sealing effectiveness can only be increased by the length lengthening screw thread, sealing effectiveness is bad, impracticable.
Utility model content
For above-mentioned situation; for overcoming the defect of prior art; the object of the utility model is just to provide a kind of stem cell cryopreserving protection of pipe cover; it can directly be sleeved on existing cryopreservation tube; can directly need not use its repacking; and another use is not affected when cryopreservation tube or any one damage of protective sleeve, and which increase rubber stopper seal, sealing effectiveness is better.
Its solution is, comprise the base that the pipe lid of lower openings and upper end are provided with cylindrical cell body, the sidewall of cylindrical cell body is fitted with the first rubber bush, multiple vertical connector is circumferentially fixed in interval around cylindrical cell body in base upper end, the other end of connector is fixed on the vertical branch sleeve lower end be placed in above base, second rubber bush coaxial with the first rubber bush is equipped with in branch sleeve, branch sleeve is provided with external screw thread, first rubber bush and the second rubber bush and cryopreservation tube closely cooperate, described branch sleeve lower end stretches out and is provided with circular fold, circular fold upper surface is provided with sealing gasket, the internal thread matched with external screw thread is provided with inside described pipe lid bottom opening, top in pipe cover gab is provided with rubber stopper close-fitting with the cryopreservation tube mouth of pipe.
The utility model protective sleeve can be used on the different cryopreservation tubes coordinated with it; be demountable structure with cryopreservation tube; easy to use; cryopreservation tube need not be reequiped, even if cryopreservation tube damages also by this application of installation in other cryopreservation tubes, can save resource; and good sealing effect; effectively stopped the pollution of stem cell in cryopreservation tube, base can make cryopreservation tube be placed on any platform, easy to use.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Provided by Fig. 1 to Fig. 6, the utility model comprises the base 2 that the pipe lid 1 of lower openings and upper end are provided with cylindrical cell body 201, the sidewall of cylindrical cell body 201 is fitted with the first rubber bush 202, multiple vertical connector 3 is circumferentially fixed in interval around cylindrical cell body 201 in base 2 upper end, the other end of connector 3 is fixed on vertical branch sleeve 4 lower end be placed in above base 1, second rubber bush 5 coaxial with the first rubber bush 201 is equipped with in branch sleeve 4, branch sleeve 4 is provided with external screw thread 401, first rubber bush 201 and the second rubber bush 5 closely cooperate with cryopreservation tube 6, described branch sleeve 4 lower end stretches out and is provided with circular fold 402, circular fold 402 upper surface is provided with sealing gasket 403, the internal thread 101 matched with external screw thread 401 is provided with inside described pipe lid 1 bottom opening, top in pipe lid 1 opening is provided with rubber stopper 7 close-fitting with cryopreservation tube 6 mouth of pipe.
Described connector 3 is elastic component, its degree of depth that pipe lid 1 can be coordinated to screw, and the lower end of pipe lid 1 can be made simultaneously more tight with coordinating of rubber stopper 7, provide a uplift force to base 2 simultaneously.
Described connector 3 is non-elastic member, and it can play the effect of support and connection sleeve 4, and can, to base 2 one uplift forces, make the cooperation of base 2 and cryopreservation tube 6 more fastening in time screwing pipe lid 1 downwards.
The bottom of described pipe lid 1 is provided with sealing ring, and sealing ring coordinates with sealing gasket 403 and makes sealing effectiveness better.
Upper end in described first rubber bush 202 is provided with chamfering, cryopreservation tube 6 is inserted wherein convenient.
Upper end in described second rubber bush 5 is provided with chamfering, cryopreservation tube 6 is inserted wherein convenient.
Described rubber stopper 7 rotates and is fixed on pipe lid 1, and when pipe lid 1 is rotated down time, rubber stopper 7, due to the frictional force with body, makes rubber stopper 7 not rotate relative to body, moving downward advantageously in rubber stopper 7, makes cooperation tightr.
When the utility model uses, the body of cryopreservation tube 7 is inserted on the first sleeve 202 on base 2 through the second sleeve 5, then the internal thread 101 of pipe lid 1 is coordinated with the external screw thread 401 of branch sleeve 4, rotate pipe lid 1, make pipe lid 1 constantly downward relative to body, drive rubber stopper 7 to be constantly inserted in cryopreservation tube 6 simultaneously, finally the lower end of pipe lid 1 is pressed on sealing gasket 403, because the second rubber bush 5 closely cooperates with body, therefore the second rubber bush 5, an annular seal space is formed between body and pipe lid 1, stop entering of bacterium and microorganism, and rubber stopper 7 further sealed tube body, make the sealing effectiveness of body more firm, base 1 can make cryopreservation tube be placed on any platform, easy to use.
The utility model protective sleeve can be used on the different cryopreservation tubes coordinated with it; be demountable structure with cryopreservation tube; easy to use; cryopreservation tube need not be reequiped, even if cryopreservation tube damages also by this application of installation in other cryopreservation tubes, can save resource; and good sealing effect; effectively stopped the pollution of stem cell in cryopreservation tube, base can make cryopreservation tube be placed on any platform, easy to use.
