The multifunctional anti-pollution test tube rack for the chemical experiment comprises a base, wherein a center shaft is vertically arranged in the center of the base. The multifunctional anti-pollution test tube rack for the chemical experiment is characterized in that a rotating cylinder is sleeved on the center shaft; a cone disk is fixedly arranged on the bottom of the rotating cylinder; two sliding disks are sleeved in the middle of the rotating cylinder; grooves which are distributed uniformly are formed along the axial direction in the outer wall of the rotating cylinder; convex rings are fixedly arranged at the central holes of the sliding disks; positioning pins are movably arranged in horizontal through holes of the convex rings; through holes which correspond to each other are formed in the two sliding disks; a label bag is arranged on the side wall of the sliding disk on the lower side; a transparent protective cover is movably arranged on the base; a through hole in the top of the transparent protective cover is sleeved on the upper part of the rotating cylinder. The multifunctional anti-pollution test tube rack for the chemical experiment is simple in structure, reasonable in design and small in occupied space; the observation and comparison of students are facilitated; the safety of the students can be guaranteed; the operation of a teacher is facilitated.
Description
Technical field
The utility model relates to a kind of chemical experiment apparatus, is specifically related to a kind of chemical experiment Multifunction anti-pollution test-tube stands.
Background technology
At present, teacher, when testing, need to use rack for test tube, and test tube pore diameter size on existing rack for test tube is consistent, the test tube that diameter is less than pore like this, after being inserted on rack for test tube, just there will be inclination, be not easy to observe, can not regulate according to the height of test tube, impact experiment; After cleaning test tube, also need to be upside down on rack for test tube to dry, the water flowing down can be hoarded in the bottom of rack for test tube, is unfavorable in vitro keeping clean simultaneously.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and can carry out timely adjustment according to the height of test tube, and make test tube remain plumbness, is convenient to observation of students contrast, safety non-pollution, the chemical experiment Multifunction anti-pollution test-tube stands of convenient operation.
In order to reach above object, the technical scheme that the utility model adopts is: chemical experiment Multifunction anti-pollution test-tube stands, comprise base, the center of described base is vertically provided with central shaft, it is characterized in that: on described central shaft, be arranged with rotating cylinder, the bottom of described rotating cylinder is fixed with cone dish, the middle part of described rotating cylinder is arranged with two slider disc that shape is identical, on the outer wall of rotating cylinder, be provided with the equally distributed groove arranging vertically, central hole in slider disc is fixed with bulge loop, in the horizontal through hole of bulge loop, be movably equipped with alignment pin, in two slider disc, be provided with the through hole of mutual correspondence, on the sidewall of a slider disc of downside, be provided with label bag, on base, be movably equipped with transparent shield, the through hole at transparent shield top is set in the top of rotating cylinder.
Described base is provided with drawer.The top panel of described base is provided with sump pit.
The beneficial effects of the utility model are: simple in structure, and can carry out timely adjustment according to the height of test tube, and make test tube remain plumbness, be convenient to observation of students contrast, safety non-pollution, convenient operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, base; 2, central shaft; 3, rotating cylinder; 4, cone dish; 5, bulge loop; 6, slider disc; 7, through hole; 8, transparent shield; 9, label bag; 10, alignment pin; 11, groove; 12, drawer; 13, sump pit.
The specific embodiment
As shown in Figure 1, chemical experiment Multifunction anti-pollution test-tube stands, comprise base 1, the center of described base 1 is vertically provided with central shaft 2, it is characterized in that: on described central shaft 2, be arranged with rotating cylinder 3, the bottom of described rotating cylinder 3 is fixed with cone dish 4, the middle part of described rotating cylinder 3 is arranged with two slider disc 6 that shape is identical, on the outer wall of rotating cylinder 3, be provided with the equally distributed groove 11 arranging vertically, central hole in slider disc 6 is fixed with bulge loop 5, in the horizontal through hole of bulge loop 5, be movably equipped with alignment pin 10, requirement for height that like this can be different according to each slider disc 6, alignment pin 10 is inserted in the groove 11 of differing heights, thereby two slider disc 6 are fixed on rotating cylinder 3, in two slider disc 6, be provided with the through hole 7 of mutual correspondence, on the sidewall of a slider disc 6 of downside, be provided with label bag 9, different test tubes in test are made a mark, the diameter of through hole 7 is identical with the caliber of test tube, thereby being contacted with the inwall of through hole 7, test tube do not have gap, like this when test tube insert the upper and lower corresponding through hole 7 of two slider disc 6 interior after, test tube remains plumbness, be convenient to observe, on base 1, be movably equipped with transparent shield 8, the through hole at transparent shield 8 tops is set in the top of rotating cylinder 3.
Described base 1 is provided with drawer 12.By drawer 12, can deposit various experiment appliances, convenient experiment is used.
The top panel of described base 1 is provided with sump pit 13, and the inner of sump pit 13 is positioned at the chamber of transparent shield 8.
During use, by adjusting the height of two slider disc 6, and two slider disc 6 are separately fixed on rotating cylinder 3, and make the top of test tube through two slider disc 6, the bottom of test tube is placed on cone dish 4, so that test tube keeps vertical, finally transparent shield 8 is located to the outside of two slider disc 6, when needs are observed test tube, can rotate the upper end of the rotating cylinder 3 at outstanding transparent shield 8 tops, to facilitate observation, so both guaranteed that invisible spectro reactant was not contaminated, also observation easily.To the test tube after cleaning, can be upside down on cone dish 4, water flows down along the inclined-plane of cone dish 4, because the lower edge of transparent shield 8 contact with base 1, coincide, and after inclined base 1, water can only flow into the interior discharge of sump pit 13, the cleanliness factor after the cleaning of assurance test tube.
