Abstract
The utility model provides a dewar bottle with bottle lid, including bottle and sample cell, its characterized in that, the bottle top still is equipped with the lid, the upper end of lid is the disc type, is equipped with the through -hole in the disc type quotation of lid, and the sample cell can penetrate the through -hole, the upper end of sample cell is equipped with the block that elastic material made, the sample cell top is equipped with limit structure. The utility model provides a dewar bottle with bottle lid can overcome the prior art dewar does not have the lid, directly puts the sample cell and enters, and the liquid nitrogen is easy to flow out and the technical problem of the position of out -of -control sample cell. The utility model discloses simply, reliably, after the verification dewar bottle was increasing bottle lid and capsule many times, the sample cell position control of not only being convenient for made things convenient for the sample test, and it is bad to prevent also that the glass sample cell from bumping, has gained good technological effect.
Description
Technical field
This utility model relates to the Dewar flask of a kind of use for laboratory.A kind of Dewar flask with bottle cap.
Background technology
Dewar flask, is again hot water bottle, thermos flask.(Dewars) it is that storage liquid gas, low temperature research and crystal element are protected
The more satisfactory container of one protected and instrument.Modern Dewar flask is Scotland physicist and chemist James-Dewar jazz
Invention.1892, Dewar instruction Burger was by one special vial of glass blowing.This is a Double-layer glass vessel, two
Layer bottle with glass liner wall all fills silver, then the air between two layers of walls is taken out, and forms vacuum.Silver on two-layer gallbladder wall is possible to prevent spoke
Penetrating heat radiation, vacuum-energy prevents convection current and heat loss through conduction, is therefore contained in the liquid in bottle, and temperature is not susceptible to change.
The Dewar that prior art uses does not has lid, and namely directly setting-out QC is entered, dynamics improperly in the case of,
Liquid nitrogen is easy the most out, and the position of uncontrollable sample cell.
Summary of the invention
This utility model has aimed to overcome that above-mentioned existing existing problems, it is provided that a kind of Dewar flask with bottle cap.
Technical solution adopted in the utility model: a kind of Dewar flask with bottle cap, including bottle and sample cell, bottle
Being also arranged above lid, the upper end of described lid is collar plate shape, and disk is provided with through hole, and sample cell can penetrate through hole, described
The upper end of sample cell is provided with the block that elastomeric material is made, and described sample cell top is provided with position limiting structure.
Further: described block is cone.
Further: described block is made of plastics.
Further: the part that described lid contacts with block is made of plastics.
Further: described block side has a seam being parallel to bottle, sample cell can with block coordinate tune
The position of joint sample cell.
Further: under described block, end in contact Dewar flask body portion is additionally provided with shade.Shade can play stable
The effect of bottle.
Further: in described block, to be additionally provided with through hole and bayonet socket.Through hole can be many in rear discharge test tube on bottle cap lid
Remaining gas, and the air pressure in bottle can be kept bottle variations in temperature when.Bayonet socket can be by outside with bottle top
Preferably coupling is done at prominent position so that bottle is difficult to rock, it is possible to plays and does not allows liquid in bottle spill the effect come.
This utility model has the beneficial effects that:
1. this utility model low cost, Simple And Practical, effect is preferable.
2. this utility model can be more suitable for testing use, the liquid that the liquid nitrogen etc. used for loading experiment is tested
Body.
Accompanying drawing explanation
Fig. 1 is this utility model population structure；
Fig. 2 is this utility model Bottle cap structure figure；
Fig. 3 is the structure chart that this utility model block is combined with sample cell；
Fig. 4 is the structure chart that this utility model block is decomposed with sample cell；
Fig. 5 is this utility model capping structure figure.
Wherein, 1 is bottle, and 2 is sample cell, and 3 is cone lid, and 4 is block, and 5 is position limiting structure, and 6 is elastic material
Block shade, 7 is through hole, and 8 is bayonet socket, and 9 is the seam being parallel to bottle in block.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described further:
Embodiment 1
As it is shown in figure 1, a kind of Dewar flask with bottle cap, including bottle and sample cell, it is characterised in that；Above bottle also
Being provided with lid, the upper end of described lid is collar plate shape, and disk is provided with through hole, and sample cell can penetrate through hole, described sample cell
Upper end be provided with the block that plastics are made, block is cone, and block side has a seam being parallel to bottle, and sample cell can
With the position coordinating regulation sample cell with block, sample cell top is provided with position limiting structure, and position limiting structure plays and do not allows sample cell
All submerge the effect of bottle.
Embodiment 2
As it is shown in figure 1, a kind of Dewar flask with bottle cap, including bottle and sample cell, it is characterised in that；Above bottle also
Being provided with lid, the upper end of described lid is collar plate shape, and disk is provided with through hole, and sample cell can penetrate through hole, described sample cell
Upper end be provided with the block that rubber is made, block is cone, and block side has a seam being parallel to bottle, and sample cell can
With the position coordinating regulation sample cell with block, sample cell top is provided with position limiting structure, and position limiting structure plays and do not allows sample cell
All submerge the effect of bottle.
This utility model is not limited to above-described detailed description of the invention, the foregoing is only this utility model the most real
Execute example, not in order to limit this utility model, all this utility model spirit and principle within made any amendment, etc.
With replacement and improvement etc., within should be included in this utility model protection domain.
