Abstract
The utility model belongs to experiment equipment design field, relate to a kind of Novel test tube holder, comprise two jig arm and a handle, the liner plate of a rectangle is connected and fixed on the downside of the jig arm be connected with handle, four angles of liner plate are respectively provided with the staple that is used for fixing background paper, the cuvette groove that a vertical cross section is " U " type is provided with in the middle part of liner plate, the sidewall of cuvette groove is inlayed the white LED lamp pearl of multiple parallel connection, LED lamp bead is electrically connected with the button cell on handle and switch by the wire be laid in liner plate.Under this New test tube is clipped in the setting off of liner plate and the observing effect of in vitro experimental phenomena can be strengthened under the illumination of LED lamp bead, use when being particularly suitable for lecture experiment.
Description
Technical field
The utility model belongs to experiment equipment design field, relates to a kind of test tube clamp.
Background technology
Test tube clamp is that a kind of gripping test tube that is used for carries out chemical experiment or shows a kind of common experimental equipment of 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 test tube clamp function singleness only has the function of gripping test tube, and the function of experimental phenomena effect is shown in unshielded interference or enhancing, therefore carry out the observing effect of lecture experiment with traditional test tube clamp poor, 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 test tube clamp, and design provides a kind of and has the interference that can stop masked segment light or surrounding scenes, has the auxiliary Novel test tube holder strengthening lecture experiment observing effect.
For realizing above-mentioned technical problem, the Novel test tube holder that the utility model relates to, comprise two jig arm and a handle, the liner plate of a rectangle is connected and fixed on the downside of the jig arm be connected with handle, four angles of liner plate are respectively provided with the staple that is used for fixing background paper, the cuvette groove that a vertical cross section is " U " type is provided with in the middle part of liner plate, the sidewall of cuvette groove is inlayed the white LED lamp pearl of multiple parallel connection, LED lamp bead is electrically connected with the button cell on handle and switch by the wire be laid in liner plate.
The colour temperature of described white LED lamp pearl is: 5000-6000K.
Compared with the existing technology, the beneficial effects of the utility model are: because the utility model is provided with liner plate and LED lamp bead, therefore when making different lecture experiments can by change different colours background paper and under the illumination of LED lamp bead, avoiding the contrast that can increase the object of observation around test tube while other scenery and extraneous light excessive interference, thus the observing effect of Enhancement test phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the circuit connection diagram of LED 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 Novel test tube holder that the utility model relates to, comprise two jig arm 1 and a handle 2, the liner plate 3 of a rectangle is connected and fixed on the downside of the jig arm 1 be connected with handle 2, four angles of liner plate 3 are respectively provided with the staple 4 that is used for fixing background paper, the cuvette groove 5 that a vertical cross section is " U " type is provided with in the middle part of liner plate 3, the sidewall of cuvette groove 5 is inlayed the white LED lamp pearl 6 of multiple parallel connection, LED lamp bead 6 is electrically connected with the button cell 7 on handle 2 and switch 8 by the wire be laid in liner plate.As a kind of preferred embodiment of the present utility model, the colour temperature of described white LED lamp pearl is: 5000-6000K.
In use process of the present utility model, the background paper of suitable color can be selected according to different Chemical Experimental Phenomenas, fixing with staple 4 in corresponding background paper lay to liner plate 3 and cuvette groove 5 and LED lamp bead 6 being come out, the middle and upper part that so latter two jig arm 1 clamps test tube can be carried out relevant presentation and tested.Liner plate 3 and background paper can stop or shield a part of external interference light around test tube on the one hand, and another aspect can also play some and set off effect, thus the contrast of the increase object of observation, therefore can the observing effect of Enhancement test phenomenon; If when indoor light crosses weak impact observation invisible spectro experimental phenomena, can be connected the power supply of white LED lamp pearl 6 by switch 8, then the light close to daylight that white LED lamp pearl 6 sends will illuminate test tube interior, thus improves observing effect further.
Claims (2)
