Description
Technical field
Protecting box field is the utility model is related to, in particular, it is related to a kind of guarantor of SEM sample
Protect box.
Background technology
SEM（SEM）It is the relatively modern RESEARCH ON CELL-BIOLOGY instrument of nineteen sixty-five invention, with scanning
The update of Electronic Speculum, not only in cell biology, and have widely in other fields such as material science, ore assay etc.
Using.But as SEM use range is more and more wider, corresponding sample is also more and more, how effectively to preserve
Sample is a problem, particularly some precious electron microscopic samples for needing to preserve for a long time, and Sample storage box it is also proposed newly
Requirement.
Preferable Sample storage requirement, 1, vacuum environment, electron microscopic observation chamber is simulated, reach the optimum state of Sample storage.
The more difficult operation of this point, but for substantial amounts of sample, a closed container can be positioned over together and vacuumized together, or for
A small amount of precious sample, carries out vacuumizing preservation.But so operation has a disadvantage, will not if often to pick and place sample
It is convenient.2, sample is fixed and isolated with surrounding articles.Most of electron microscopic sample conserving case is both for this click-through on the market
Exploitation is gone, but has been only limitted to tee T sample stage, there is porous plate, may be inserted into sample stage, a box preserves multiple.This sample
The inconvenience of box is due to that sample is in same box, can not effectively completely cut off interfere between each other, such as samples setting-out.
If sample box receives larger vibrations, the sample in original sample box is still very likely excessively led due to picking and placeing number
Socket is caused to fluff and be easier to drop.More importantly for screw socket electron microscopic sample platform, also led without corresponding fixed bin, this point
Such sample stage is caused easily to be destroyed by ectocine.3, sample mark is simple, picks and places conveniently.For tee T electron microscopic sample platform
Conserving case, it can meet that in general marks, but if wanting separate marking and not influenceing sample, this kind of and box is just more difficult full
This requirement of foot, while it is related to the problem of interfering, this kind of conserving case can also interfere in the fetching process of sample.4,
Conserving case price is low.The Sample storage box unit price of general import is all more than 150 yuan, and each box can only preserve on a small quantity
Sample, for the more user of sample size, a kind of cheap conserving case effectively can help researcher to protect
More samples are deposited in favor of sample comparative studies.
Although in the market has the demand of this respect, in view of electron microscopic sample platform is not belonging to mass product, corresponding company
The feedback in market is have ignored, in the market is also without the matured product of this respect.The present invention is aiming at this case, with reference to itself
Research practice demand develops a kind of conserving case of new SEM sample stage.
The content of the invention
The utility model overcomes the deficiencies in the prior art, and a kind of new scanning is developed with reference to research practice demand itself
The conserving case of electron microscope sample desk, its cost savings, easy to operate, protection is strong.
The technical solution of the utility model is as follows：
A kind of protecting box of SEM sample, including containment vessel and installation are covered, and the containment vessel includes hollow out
Cylindrical portion and threaded joints, the hollow out cylindrical portion are not covered close to one end of installation lid, the hollow out cylindrical portion other end
Centrally disposed passage, rubber stopper is set on passage；The threaded joints use annulus post, the outside of threaded joints
Rotation screw thread is set, and rotation screw thread is more than or equal to 2 layers；The installation lid includes installing lid body and fixed column, the installation lid
The thread groove corresponding with threaded joints is provided with the inside of body；Described fixed column one end is fixed on installation lid body central,
The fixed column other end is provided with sample fixed thread.
Further, tag slot is provided with the outside of the hollow out cylindrical portion, to identical samples information.
Further, hex bolts is set in the fixed column.
Further, the containment vessel and installation lid all use clear glass.
Further, the containment vessel and installation lid all use highstrenghtpiston.
Advantage is the utility model compared with prior art：The utility model structure design is simple, reasonable, easy to make,
Practical, production cost is relatively low, easily promotes the use of.The utility model can simulate electron microscopic observation close to vacuum environment
Chamber, reach the preferable states of Sample storage.Sample of the present utility model can be fixed and isolate with surrounding articles.This practicality
New sample mark is simple, picks and places conveniently.

Marked in figure：Containment vessel 1, passage 11, hollow out cylindrical portion 12, threaded joints 13, installation lid 2, fixed column 21
With installation lid body 22.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of protecting box of SEM sample, including containment vessel 1 and installation lid 2.The guarantor
Protective case 1 includes hollow out cylindrical portion 12 and threaded joints 13, and the hollow out cylindrical portion 12 is not covered close to one end of installation lid 2,
The centrally disposed passage 11 of the other end of hollow out cylindrical portion 12, rubber stopper is set on passage 11, passing through evacuator will
Air in protecting box is extracted out, produces the environment of near vacuum, the inside rarefaction of air, to need vacuum to preserve, and it is dangerous tight
Lattice require that the sample of vacuum provides good carrier.The outside of hollow out cylindrical portion 12 is provided with tag slot, to identify sample
Product details.The threaded joints 13 use annulus post, and the outside of threaded joints 13 sets rotation screw thread, rotates screw thread
More than or equal to 2 layers, and rotate screw thread and compare between layers closely, minimum can reach the spacing that only screw thread itself is wide, so
Sealing protection can be effectively carried out, after installation lid 2 is loaded onto, it is not easy to so that air enters.The installation lid 2 includes installation
Lid body 22 and fixed column 21, the inner side of installation lid body 22 are provided with the thread groove corresponding with threaded joints 13, used
With sealing protection, it can also increase rubber sheet gasket in specific implementation and be arranged on threaded joints 13 or the inner side of lid body 22 is installed
On thread groove, annulus rubber also or in threaded joints 13 is set close to one end of hollow out cylindrical portion 12, to improve sealing
Property.Described one end of fixed column 21 is fixed on the center of installation lid body 22, and the other end of fixed column 21 is provided with sample fixed thread, used
To dispose sample stage, screwed hole is provided among sample stage, can be fixed in fixed column 21, this allows for sample and is placed on this guarantor
When protecting in box, without worrying to come off, interfered with each other after vibrations between sample.Further, six are set in the fixed column 21
Corner bolt, it is so economical and practical, greatly reduce production cost.
Further, the containment vessel 1 and installation lid 2 all use clear glass or transparent highstrenghtpiston, so both
Sample situation can be conveniently observed, also can provide possibility near vacuum environment.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
Art personnel, without departing from the concept of the premise utility, some improvements and modifications can also be made, these improvements and modifications
Also should be regarded as in scope of protection of the utility model.
