Description
Technical field
The utility model relates to chemical fields, and in particular to the test tube support equipment applied to chemical experiment.
Background technique
Be one kind of natural science, and property, composition, structure, variation, the use of substance are studied on molecule, atom level
On the way, the natural science of preparation method and substance changing rule.Chemistry and industry, agricultural, daily life, medicine, material etc. have ten
Divide closely connection.Such as：Coal produces the substances such as carbon dioxide after oil and natural gas burning.The object of chemical research is related to
The association between correlation or matter and energy between substance.Traditional chemistry be all usually about the contact of two kinds of substances,
Variation, that is, chemically react, or is the process that a kind of substance becomes another substance.These variations are may require that sometimes using electricity
Magnetic wave, electromagnetic wave is responsible for exciting chemical action in the middle.But with when chemistry be all not necessarily intended to about the reaction between substance.Spectrum
The relationship between research substance and light is learned, and these relationships are not related to chemically react.
In chemistry subject, it is often necessary to carry out various chemical experiments.In chemical experiment, rack for test tube is commonly used.It is existing
Rack for test tube includes pedestal and the test tube plate by several support column sides of being fixed on the base, and the bottom of test tube is from top to bottom
Through-hole on test tube plate, and move down, until being contacted with the upper surface of pedestal.
Existing rack for test tube is in holding or transfer, not convenient for the position of experimenter's holding, so that experimenter moves
When dynamic rack for test tube, when being only capable of the edge or support column of holding test tube plate, and holding the edge of test tube plate, it is easy to because of branch
The face for supportting rack for test tube is too small and rack for test tube is caused to fall off from hand, and when holding support column, since people's both hands hold support vertically
When column, the top of support column can be tilted to the direction far from body, so that test tube is skidded off from rack for test tube and fallen on the ground.
Utility model content
The utility model aim is to provide the test tube support equipment applied to chemical experiment, solves existing rack for test tube and exist
Holding or transfer in, convenient for experimenter holding position the problem of.Therefore the utility model, which is designed, is applied to chemistry
