Abstract
The utility model relates to an appliance for chemical experiments, and particularly relates to a safe test-tube rack for chemical experiments. The safe test-tube rack for the chemical experiments comprises a support, and a base fixedly connected to the lower end of the support, the support comprises an upper transversal plate and a lower transversal plate provided with test-tube holes respectively, the upper transversal plate and the lower transversal plate are arranged in parallel, and side vertical plates are fixedly connected to the both ends of each of the upper transversal plate and the lower transversal plate. The safe test-tube rack for the chemical experiments is characterized in that the base is of a hollow structure, and a magnet is embedded in the inner cavity of the base. The magnet in the base of the safe test-tube rack for chemical experiments has a function of counter weight, thus lowering the gravity centre of the test-tube rack and contributing to stability maintenance; and simultaneously, in case of being used with an iron experiment table, the test-tube rack can be attracted on the experiment table by virtue of magnetic force of the magnet, thus being prevented from being accidentally knocked over.
Description
Technical field
The utility model relates to the chemical experiment apparatus, specifically a kind of chemical experiment safety test tube stand.
Background technology
The tubulose that the test tube that uses in the chemical experiment is normally elongated for the ease of uprightly putting, is inserted in it on rack for test tube usually, and the manufacturings such as common rack for test tube employing metal or plastics, timber, bottom area is less, easily lodging.Especially for middle school teaching, number of student is more, and accident is run into rack for test tube and easily it knocked over, causes the accident.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to use, chemical experiment safety test tube stand of being not easy to knock over.
The utility model is that the technical scheme that the technical solution problem adopts is:
Chemical experiment described in the utility model comprises support with safety test tube stand and is fixedly connected on the base of support lower end, described support comprises with the upper cross plate in test tube hole, lower cross plate, upper cross plate and lower cross plate be arranged in parallel, the two ends of upper cross plate and lower cross plate are fixedly connected with cant board, it is characterized in that: described base is hollow structure, is embedded with magnet in the inner chamber of base.
After adopting technique scheme, this chemical experiment has the effect of counterweight with the magnet in the safety test tube stand base, reduced the center of gravity of rack for test tube, be conducive to keep stable, simultaneously, cooperate the irony experimental bench to use, can utilize magnetic force that rack for test tube is adsorbed on the experimental bench, avoid accident to knock rack for test tube over.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
As shown in Figure 1, chemical experiment described in the utility model comprises support with safety test tube stand and is fixedly connected on the base 2 of support lower end, described support comprises upper cross plate 1, the lower cross plate 3 with the test tube hole, upper cross plate 1 and lower cross plate 3 be arranged in parallel, the two ends of upper cross plate 1 and lower cross plate 2 are fixedly connected with cant board 4,5, described base 2 is hollow structure, is embedded with magnet 6 in the inner chamber of base 2.Magnet 6 can be wrapped in the inside of base 2, also can embed the bottom of base 2, can adopt a monoblock magnet, also can adopt polylith magnet.
During use, cooperate the irony testing stand, perhaps lay ferrous material below the stainless steel testing stand, when this rack for test tube was placed on the testing stand, magnet and testing stand were attached together, and were not easy lodging, had guaranteed the safety of experiment.
