The utility model discloses the test tube jack is separated by through the spring strip, and the aperture of every test tube jack can elastic adjustment, puts into the tubular container in different apertures simultaneously, adopting drawer -type structure, can once only holding a large amount of tubular containers, the area occupied is little, is convenient for store and remove.
Description
Technical field
The utility model relates to a kind of chemical experiment apparatus, is specifically a kind of aperture adjustable chemistry teaching drawer type rack for test tube.
Background technology
Experiment is the important step in process of general chemistry teaching, in chemical experiment process, need the test tube of various different size, different-diameter, centrifuge tube, colorimetric cylinder, all kinds of sampling pipe, existing rack for test tube is generally only can the tubular container of a certain specification of fixed placement, and the tubular container limited amount placed, when carrying above described tubular container in a large number, the rack for test tube number ratio of needs is more, area occupied is larger, carries inconvenience.
Utility model content
Problem to be solved in the utility model is to provide a kind of aperture adjustable chemistry teaching drawer type rack for test tube, and this apparatus structure is simple, easy to use, the tubular container that simultaneously can hold a large amount of different tube diameters, and area occupied is little, conveniently moving.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of aperture adjustable chemistry teaching drawer type rack for test tube, comprise support, it is characterized in that: described support is provided with rack for test tube drawer, described rack for test tube drawer is provided with rack for test tube body, described rack for test tube body is provided with the test tube jack of array, and two the test tube jacks that are connected are separated by by spring, are provided with collet below described each test tube jack.
Preferably, described rack for test tube drawer is provided with drawer handle.
Preferably, described spring be arranged in parallel for two-layer up and down.
Preferably, described spring is transversely provided with at least one, is longitudinally provided with at least one.
Preferably, described collet is provided with the collet hole corresponding with described test tube jack, and the diameter in described collet hole is less than the base diameter of test tube.
Technique effect of the present utility model is mainly reflected in: (1) test tube jack is separated by by spring, and therefore, the aperture of each test tube jack can flexible adjustment, can put into the tubular container of different pore size simultaneously; (2) adopt drawer-type structure, disposablely can hold a large amount of tubular containers, area occupied is little, is convenient to storage and the movement of tubular container.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1, 2, 3, 4, shown in 5, a kind of aperture adjustable chemistry teaching drawer type rack for test tube, comprise support 1, described support 1 is provided with rack for test tube drawer 2, described rack for test tube drawer 2 is provided with drawer handle 3, described rack for test tube drawer 2 inside is provided with rack for test tube body 4, described rack for test tube body 4 is provided with the test tube jack 41 of array, two the test tube jacks 41 that are connected are separated by by spring 42, described spring 42 be arranged in parallel for two-layer up and down, described spring 42 every layer be transversely provided with at least one, longitudinal direction is provided with at least one, collet 43 is provided with below described each test tube jack 41, described collet 43 is provided with the collet hole 44 corresponding with described test tube jack 41, the diameter in described collet hole 44 is less than the base diameter of test tube.
During use, rack for test tube drawer 2 is pulled open, the tubular container of different tube diameters is inserted in the test tube jack 41 of rack for test tube body 4, be placed on bottom test tube on the collet hole 44 on collet 43, be convenient to the fixing of test tube.Because adjacent test tube jack 41 is separated by by spring 42, therefore, the aperture of each test tube jack 41 can flexible adjustment, can put into the tubular container of different pore size simultaneously; Owing to have employed drawer-type structure, the utility model disposablely can hold a large amount of tubular containers, and area occupied is little, is convenient to its storage and movement.
Embodiment recited above is described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
