Abstract
The utility model provides a chemical test tube rack, which belongs to chemical appliances and structurally comprises a base and a fixing disc. The fixing disc is fixed above the base, a positioning column is disposed in the center of the upper surface of the base, the lower end of the positioning column is perpendicularly connected with the base, the upper end of the positioning column penetrates through the center of the fixing disc, the positioning column is fixedly connected with the fixing disc, fixing grooves are disposed on the base and surround the positioning column, a cover plate is disposed above the fixing disc, and the center of the cover plate is disposed at the upper end of the positioning column and slidably connected with the upper end of the positioning column. Compared with the prior art, the chemical test tube rack has the advantages that the chemical test tube rack is reasonable in design, simple in structure and convenient in use, prevents dust from falling into test tubes, and the like.
Description
Technical field
The utility model relates to a kind of chemical test apparatus, and specifically a kind of chemistry is used rack for test tube.
Background technology
Test tube is a kind of utensil that the most often uses in the chemical experiment, and test tube is as glass tube, and it deposits inconvenience, especially when stopping to test, in vitro falls into dust easily, influences the accuracy of chemical test.Existing test tube mostly is to be placed in the rack for test tube, and existing rack for test tube mostly is a woodwork, and is directly that test tube is therein transversely arranged, and the test tube number of putting is limited.
Summary of the invention
The technical assignment of the utility model is the deficiency to prior art, provides a kind of chemistry reasonable in design, simple in structure to use rack for test tube.
The utility model solves the technical scheme that its technical problem adopted: comprise base; Also comprise fixed disk; Fixed disk is arranged on the base top, and the base upper surface center is provided with reference column and is connected with its lower end is vertical, and the reference column upper end is passed the fixed disk center and is fixedly connected with it; Be provided with holddown groove around reference column on the base, be provided with through hole around reference column on the fixed disk, the fixed disk top is provided with cover plate, and the cover plate center is arranged on the reference column upper end and is slidingly connected with it.
Base diameter is identical with the fixed disk diameter.
Cover plate is circular, and the cover plate upper surface is provided with handle.
The position of holddown groove is corresponding with through hole.
A kind of chemistry of the utility model with rack for test tube compared with prior art, the beneficial effect that is produced is:
Have characteristics such as reasonable in design, simple in structure, easy to use, easy operating, practicality; Can place more test tube, and can simultaneously a plurality of test tubes be sealed, prevent that dust from falling into test tube; Improve the accuracy of chemical test, improved classroom teaching efficiency.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Among the figure: 1, handle, 2, cover plate, 3, test tube, 4, reference column, 5, fixed disk, 6, through hole, 7, base, 8, holddown groove.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done following the detailed description.
Shown in accompanying drawing; A kind of chemistry of the utility model is used rack for test tube; Its structure comprises base 7, also comprises fixed disk 5, and fixed disk 5 is arranged on base 7 tops; Base 7 upper surface centers are provided with reference column 4 and are connected with its lower end is vertical, and reference column 4 upper ends are passed fixed disk 5 centers and are fixedly connected with it; Be provided with holddown groove 8 around reference column 4 on the base 7, be provided with through hole 6 around reference column 4 on the fixed disk 5, fixed disk 5 tops are provided with cover plate 2, and cover plate 2 centers are arranged on reference column 4 upper ends and are slidingly connected with it.
Through handle 1 cover plate 2 is taken down, test tube 3 is taken out use; After finishing using, again test tube 3 is put into wherein, and, avoided falling in the test tube 3 dust or other materials with cover plate 2 lids in the above.
Except that the described technical characterictic of specification, be this professional's known technology.
