Embodiment Construction
[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0018] See Figure 1-3 , A test tube placement rack for chemical experiments, including a base 1. The top of the base 1 is fixedly connected with two symmetrical columns 2 and two symmetrical storage boxes 6, ensuring the stability of the columns 2 and the storage box 6. The column 2 can effectively support the telescopic rod 8, and the placing box 6 can effectively place the test tube. The test tube can be taken and placed more convenie...

The invention discloses a test tube placing rack for chemical experiments. The test tube placing rack comprises a base, wherein two symmetrical upright posts and two symmetrical placing boxes are fixedly connected to the top of the base respectively; telescopic rods are fixedly connected to the tops of the two upright posts; a control switch is arranged on one side surface of each of the two telescopic rods; the tops of the two telescopic rods are fixedly connected to the bottom of a first transverse plate; equidistantly arranged first placing holes are formed in the first transverse plate; a second transverse plate is arranged right below the first transverse plate. Through the test tube placing rack, test tubes can be fetched and stored flexibly, so that the test tube placing rack is more convenient to operate, time-saving and effort-saving; the test tube placing rack can effectively fix the test tubes, so that the experimental efficiency is high and the fixing effect is good; the test tube placing rack can effectively limit positions of the test tubes, so that loose or damage of the test tubes is flexibly and effectively avoided and the safety performance is higher; therefore, the test tube placing rack effectively solves the problems that the test tubes are inconvenient to fetch and store and are easy to loose.
Description
Technical field [0001] The invention relates to the technical field of chemical experiment instruments, in particular to a test tube placement rack for chemical experiments. Background technique [0002] The relationship between mankind and chemical industry is very close, and it has spread to all aspects of life. Some chemical products have played an epoch-making important role in the history of human development. Their production and application even represent a certain historical stage of human civilization. Broadly speaking, Anything that uses chemical methods to change the composition or structure of a substance, or synthesize a new substance, is a chemical production technology, that is, a chemical process. The resulting product is called a chemical or chemical product. The test tube rack is a commonly used chemical laboratory equipment , The test tube rack is the most basic experimental instrument used to place and dry the test tubes in the chemical laboratory. The general...
