Abstract
The utility model belongs to experiment equipment design field, relate to a kind of test tube stand, comprise base, support body and multiple test tube jack, a liner plate be vertically fixed on base is provided with at the rear of support body, the top of liner plate is provided with a spring fixed clamp, geometrical clamp accompanies the background paper of multiple different colours; On base, position opposing upper and lower with jack is provided with multiple test tube support nest becoming semicircle spherical to lower recess, inlay the white LED lamp pearl that a colour temperature is 5000-6000K in each holder nest, multiple LED lamp bead forms in parallel electrical connection by the wire be laid in base with the switch of the button cell in base and base side.This test tube stand is under the setting off of liner plate and background paper and can strengthen contrast and the definition of the in vitro object of observation under the illumination of LED lamp bead, thus adds viewing distance, enhances the observing effect of experimental phenomena, uses when being particularly suitable for making lecture experiment.
Description
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, be subject to the interference of other scenery and extraneous light around test tube because test tube is tiny in the process of showing experimental phenomena, and traditional rack for test tube function singleness only has the function holding test tube, and the function of experimental phenomena effect is shown in unshielded interference or enhancing, therefore the observation definition of lecture experiment is carried out with traditional rack for test tube poor, viewing distance is short, thus can not meet the needs of lecture experiment.
Summary of the invention
The technical problems to be solved in the utility model is: the deficiency overcoming traditional rack for test tube, design provides a kind of and has the interference that can stop masked segment light or surrounding scenes, improve and observe definition and viewing distance, strengthen the test tube stand of lecture experiment observing effect.
For realizing above-mentioned technical problem, the test tube stand that the utility model relates to, comprise base, support body and multiple test tube jack, a liner plate be vertically fixed on base is provided with at the rear of support body, the top of liner plate is provided with a spring fixed clamp, geometrical clamp accompanies the background paper of multiple different colours; On base, position opposing upper and lower with jack is provided with multiple test tube support nest becoming semicircle spherical to lower recess, inlay the white LED lamp pearl that a colour temperature is 5000-6000K in each holder nest, multiple LED lamp bead forms in parallel electrical connection by the wire be laid in base with the switch of the button cell in base and base side.
Compared with the existing technology, the beneficial effects of the utility model are: because the utility model rack for test tube is provided with liner plate and LED illumination lamp pearl, therefore when making different lecture experiments can by change different colours background paper and under the illumination of LED lamp bead, avoiding contrast and the definition that the object of observation around test tube, while other scenery and extraneous light excessive interference, can be increased, thus add viewing distance, enhance the observing effect of experimental phenomena, use when being particularly suitable for making lecture experiment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the circuit connection diagram of LED lamp bead of the present utility model.
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 shown in Figure 1, 2: the test tube stand that the utility model relates to, comprise base 1, support body 2 and multiple test tube jack 3, a liner plate 4 be vertically fixed on base 1 is provided with at the rear of support body 2, the top of liner plate 4 is provided with a spring fixed clamp 5, geometrical clamp 5 accompanies the background paper 6 of multiple different colours; Base 1 is provided with multiple test tube support nest 7 becoming semicircle spherical to lower recess with jack 3 position opposing upper and lower, inlay the white LED lamp pearl 8 that a colour temperature is 5000-6000K in each holder nest 7, multiple LED lamp bead 8 forms in parallel electrical connection by the wire be laid in base 1 with the switch 10 of the button cell 9 in base and base side.
In use process of the present utility model, can the background paper of suitable color be selected according to different Chemical Experimental Phenomenas and fix with geometrical clamp 5, liner plate 4 and background paper can stop or shield the interference of the extraneous light of a part around test tube on the one hand, 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; If when indoor light crosses weak impact observation invisible spectro experimental phenomena, the power supply of white LED lamp pearl 8 can be connected by switch 10, the light close to daylight that then white LED lamp pearl 8 sends will illuminate test tube interior, thus improve observation definition and viewing distance further, there is good observing effect.
