Abstract
An anti-shaking test tube clamp belongs to chemical experiment supplies and mainly solves the problem that chemical reagents are easy to spill out when the chemical reagents are dripped into a test tube. The anti-shaking test tube clamp structurally comprises a round ring and clamp heads, and the diameter of the round ring is slightly bigger than the inner diameter of the test tube. Two sides of the round ring are respectively provided with a spring steel sheet, and the tail end of each spring steel sheet is provided with an arc-shaped clamp head. The anti-shaking test tube clamp adopts a structure that the round ring is fixed above a test tube mouth so that a tip end of a dropper can be guided to accurately point to the test tube mouth and shakes of the dropper can be restricted when solution is dripped into the test tube, and therefore the anti-shaking test tube clamp avoids spilling the solution.
Description
Technical field
The utility model relates to a kind of chemical experiment articles for use, specifically a kind of test tube clamp.
Background technology
Test tube is an experimental facilities commonly used in the chemical experiment; It provides as chemical solvent usually and deposits and test; Owing to usually use in the experiment and relate to poisonous and corrosive reagent; Therefore chemical reagent does not allow to be sprinkled upon the place beyond the test tube, but the student when operation experiments because unskilled, still have the dangerous hidden danger of spilling when in test tube, splashing into reagent.
The utility model content
The purpose of the utility model is to provide a kind of prevents trembling test tube clamp, mainly solves and in test tube, splashes into the problem that chemical reagent spills easily.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of anti-test tube clamp of trembling; Its structure comprises annulus and the chuck of somewhat larger in diameter in the test tube internal diameter; Described annulus both sides respectively are provided with a spring steel plate, and the spring steel plate end is provided with the chuck of arc.
The radius of curvature of described chuck is identical with the test tube external diameter.
The beneficial effect of the utility model is: be employed in the structure of test tube mouth upper fixed annulus, can guide improved pipette tip accurately to point to the test tube mouth, in the shake that when in vitro dripping solution, can limit dropper, avoid solution to spill.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 annulus, 2 spring steel plates, 3 chucks, 4 test tubes.
The specific embodiment
As shown in Figure 1.A kind of anti-test tube clamp of trembling, its structure comprise the annulus 1 and chuck 3 of somewhat larger in diameter in the test tube internal diameter, and described annulus 1 both sides respectively are provided with a spring steel plate 2, and spring steel plate 2 ends are provided with the chuck 3 of arc.
The radius of curvature of described chuck 3 is identical with test tube 4 external diameters.
During use, chuck 3 is clipped on the outer wall of test tube 4 near mouth of pipe place, by the pressure of spring steel plate 2; Make annulus 1 can through chuck 3 be securely held on test tube 4 directly over because the somewhat larger in diameter of annulus 1 is in the internal diameter of test tube 4, so the front end of dropper is insinuated in the annulus 1 more easily; In the operation dropper drips dissolving agent process; Dropper easily shake causes solvent to spill, and annulus 1 can play the effect of constraint dropper shake, prevents that dropper from deviating from the mouth of pipe scope of test tube 4.With finishing can chuck 3 be broken into two with one's hands annulus 1 and test tube 4 are thrown off, avoid influencing the experiment in later stage.
Claims (2)
1. prevent trembling test tube clamp for one kind, it is characterized in that comprise annulus and the chuck of somewhat larger in diameter in the test tube internal diameter, described annulus both sides respectively are provided with a spring steel plate, the spring steel plate end is provided with the chuck of arc.
2. according to claim 1ly a kind ofly anti-tremble test tube clamp, it is characterized in that the radius of curvature of described chuck is identical with the test tube external diameter.
