Abstract
The utility model discloses a kind of rack for test tubes, including pedestal, two brackets, plate and elastomer.Two brackets are respectively arranged in the both ends of pedestal, the height of bracket is greater than the height of test tube, plate is installed on the upper end of bracket, plate and pedestal it is equal in be equipped with multiple through-holes passed through for test tube, the through-hole that elastomer is located on bottom plate is interior and the diameter of elastomer is slightly less than test tube.The utility model generates contact stain when avoiding rocking, while test tube being avoided to drain using elastomer fixed test tube.
Description
Technical field
The utility model relates to experiment appliances, and in particular to a kind of rack for test tube.
Background technique
Rack for test tube is the equipment being commonly used in current experiment, and current rack for test tube is mainly by pedestal, bracket and plate structure
At, and there are several through-holes to use for test tube on plate.Its using priciple is: when using test tube, the test tube of liquid will be housed
Bottom is put into test tube jack downward, and test tube and jack contact are loose, and it is convenient to pick and place；When test tube leaves unused, by test tube mouth down
It is put into plate through-hole, can not only drain away the water but also can prevent dust from polluting.But there is following disadvantages for existing rack for test tube: one,
Test tube is put into more relaxed in rack for test tube, is unfavorable for outdoor study, is easy to rock, breakage rate is higher.The second, idle not in test tube
When with draining, test tube mouth is contacted with rack for test tube bottom surface, can generate contact stain.
Summary of the invention
The purpose of this utility model is to overcome above the shortcomings of the prior art, provide a kind of structure it is simple,
Rationally, the rack for test tube of contact stain is hardly damaged and can reduced when outdoor use.
Technical solutions of the utility model are as follows:
The rack for test tube of the utility model includes pedestal, bracket, plate, elastomer.In two bracket installations and pedestal, plate
It is installed on the upper end of bracket, multiple through-holes passed through for test tube are equipped in plate and pedestal, elastomer is located at the logical of pedestal
Kong Shang.
This rack for test tube increases elastomer on the basis of existing rack for test tube, and the diameter of elastomer is slightly less than test tube, In
When using test tube, play the role of fixed test tube.When test tube leaves unused or needs to drain away the water, test tube is passed through into elastomer, so
Rack for test tube is stood upside down afterwards, can not only drain away the water but also can avoid the contact stain of test tube mouth.
The elastomer is made of rubber or plastics, and elastomer can be designed using simple circular hole, as shown in Fig. 2,
Flanged structure can be preferably used, frictional force when test tube passes through, such as Fig. 3 can be effectively reduced in flanged structure design
It is shown.
Detailed description of the invention
Fig. 1 show the structure chart of the utility model embodiment；
Fig. 2 show being typically designed for elastomer 4.
Fig. 3 show the preferred design of elastomer 4.
Specific embodiment
Below with reference to attached drawing, the specific descriptions of the optional embodiment of the utility model are given.
Such as Fig. 1, rack for test tube includes pedestal 1, bracket 2, plate 3 and elastomer 4.Two installations of bracket 2 are inserted on pedestal 1
Plate 3 is installed on the upper end of bracket 2, and multiple through-holes passed through for test tube are equipped in plate 3 and pedestal 1, and elastomer 4 is located at bottom
On the through-hole of seat 1.
When rack for test tube is in working condition, rack for test tube is just put, and test tube easily can place frame vertically from test tube and take out or place vertically,
Pedestal of the elastomer 4 on pedestal 1 as test tube at this time consolidates test tube.
When test tube is idle or drains, test tube is passed through from the through-hole of plate 3, and passes through the elastomer 4 on pedestal 1, bullet
The internal diameter of property body 4 is slightly less than the diameter of test tube, therefore belongs to interference fit between elastomer 4 and test tube, can effectively block examination
Pipe.After test tube is placed, rack for test tube is inverted, elastomer 4 can clamp test tube without falling off, and bracket 2 is slightly above
Test tube, test tube is in the state of suspension when rack for test tube is inverted, test tube mouth the problem of there is no contact stains.
The elastomer 4 is made of rubber or plastics, can effectively ensure that card using elastomer 4 made of elastic material
Position clamps the stability and fastness when test tube, guarantees effective progress of draining.
