Description

Test tube stand

Technical field

The utility model belongs to experiment equipment design field, relates to a kind of rack for test tube.

Background technology

Rack for test tube is that a kind of being used for holds a kind of common experimental equipment that test tube carries out chemical experiment or displaying experimental phenomena, because test tube is tiny in the process of showing experimental phenomena, but also be subject to the interference of test tube back side light line and scenery, therefore not only viewing distance is short, and poor contrast is not easily observed clear, and traditional rack for test tube function singleness and without reducing backlight interference or the function of Enhancement test Phenomena Observation effect, thus the needs of lecture experiment can not be met.

Summary of the invention

The technical problems to be solved in the utility model is: the deficiency overcoming traditional rack for test tube, and design provides a kind of interference that can reduce dorsal part light and scenery, improves the test tube stand observing definition and viewing distance, enhancing lecture experiment observing effect.

For realizing above-mentioned technical problem, the test tube stand that the utility model relates to, comprise support body and base, support body is a transparent cylinder, in support body, being provided with one, to run through its upper and lower cross section be foursquare test tube jack, before and after support body is partitioned into by test tube jack, four, left and right is the vertical bar shape convex lens spliced mutually, support body is vertically fixed on a cylinder base, the socket bore bottom a support test tube is provided with in the center of base upper surface, the white LED lamp pearl that a colour temperature is 5000-6000K is inlayed in socket bore, LED lamp bead is formed by the switch being laid in wire in base and the button cell in base and base side and is electrically connected, be provided with an arcuate slot at the edge of base upper surface, be inserted with background paper in slot, the top of background paper is fixed on the upper end of support body by a rubber ring.

Compared with the existing technology, the beneficial effects of the utility model are: because the transparent column bodily form support body of the utility model rack for test tube is partitioned into the mutual convex lens connected vertically in four, all around by test tube jack, and convex lens have amplification, the test tube and the interior experimental phenomena thereof that are placed in test tube jack can be exaggerated certain multiple, thus add viewing distance; And background paper and LED illumination lamp pearl, then can reduce the interference of other scenery of test tube dorsal part and extraneous light, increase contrast and the definition of the object of observation, the observing effect of Enhancement test phenomenon, uses when being particularly suitable for making lecture experiment.

Detailed description of the invention

Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment:

As Fig. 1, 2, shown in 3: the test tube stand that the utility model relates to, comprise support body 1 and base 2, support body 1 is a transparent cylinder be made up of glass, in support body 1, being provided with one, to run through its upper and lower cross section be foursquare test tube jack 3, before and after support body 1 is partitioned into by test tube jack 3, four, left and right is the vertical bar shape convex lens 4 spliced mutually, support body 1 is vertically fixed on a cylinder base 2, the socket bore 5 bottom a support test tube is provided with in the center of base 2 upper surface, the white LED lamp pearl 6 that a colour temperature is 5000-6000K is inlayed in socket bore 5, LED lamp bead 6 is formed by the switch 8 being laid in wire in base 2 and the button cell 7 in base 2 and base side and is electrically connected, be provided with an arcuate slot 9 at the edge of base 2 upper surface, be inserted with background paper 10 in slot 9, the top of background paper 10 is fixed on the upper end of support body 1 by a rubber ring 11.

In use process of the present utility model, the background paper 10 of suitable color can be selected to be plugged on blend rubber ring 11 in slot 9 according to different Chemical Experimental Phenomenas to fix, then the test tube that will demonstrate is inserted in test tube jack 3, background paper 10 1 aspect can stop or reduce a part of scenery of test tube dorsal part and the interference of extraneous light, can also play some sets off effect on the other hand, thus increase the contrast of the object of observation, therefore can the observing effect of Enhancement test phenomenon; The support body wall being positioned at test tube front and back and the left and right sides is then partitioned into four mutual bar shape convex lens 4 connected vertically by test tube jack 3, thus test tube and interior experimental phenomena thereof are amplified, thus be convenient to front and the distant student in the left and right sides observes; If when indoor light crosses weak impact observation invisible spectro experimental phenomena, the power supply of white LED lamp pearl 6 can be connected by switch 8, the light close to daylight that then white LED lamp pearl 6 sends will illuminate test tube interior, thus improves observation definition and viewing distance further.
