A high school chemical test tube rack for convenient placement of test tubes

Abstract

The invention discloses a high school chemistry test tube stand facilitating placement of test tubes. The high school chemistry test tube stand facilitating placement of test tubes comprises a base, arotating device, a bottom supporting device and an upper end closing device, wherein the rotating device is arranged at the upper end of the base; a supporting plate is arranged at the upper end of arotating plate in the rotating device; and the bottom supporting device is arranged at the upper end of the supporting plate. The high school chemistry test tube stand facilitating placement of testtubes is simple in structure and safe and convenient for placement of the test tubes, is fixed firmly, and brings great convenience for a user during use; moreover, the user can take and place the test tubes at an optimal angle through the rotating device according to use requirements, stable supporting of the test tubes in a placement process is ensured through the bottom supporting device and the upper end closing device, the use safety is ensured, moreover, volatile pollution caused by sprinkling of liquid in the test tubes and untight closing is avoided, attendance vigor of people is relieved, and the using efficiency of the chemistry test tube stand is improved.

Description

technical field [0001] The invention relates to the technical field of teaching and experiment auxiliary equipment, in particular to a high school chemical test tube rack which is convenient for placing test tubes. Background technique [0002] In high school chemistry teaching courses, it is often necessary to practice the reaction of chemical reagents for students in order to let students master the knowledge of chemistry more deeply and intuitively. In the chemical experiment course, the placement of chemical test tubes is inseparable from the use of test tube racks. The traditional test tube rack only provides support, the structure is too simple, it is not safe and convenient in the process of placing the test tubes, and the test tubes are not fixed enough after placement, which brings great trouble to the user, and cannot It is convenient for users to pick and place test tubes at the best angle according to the needs of use. It cannot guarantee the stable support of th...

[0002] In high school chemistry teaching courses, it is often necessary to practice the reaction of chemical reagents for students in order to let students master the knowledge of chemistry more deeply and intuitively. In the chemical experiment course, the placement of chemical test tubes is inseparable from the use of test tube racks. The traditional test tube rack only provides support, the structure is too simple, it is not safe and convenient in the process of placing the test tubes, and the test tubes are not fixed enough after placement, which brings great trouble to the user, and cannot It is convenient for users to pick and place test tubes at the best angle according to the needs of use. It cannot guarantee the stable support of the test tubes during the placement process, cannot guarantee the safety of the test tube rack for personnel during use, and cannot avoid the spilling and airtightness of the liquid in the test tubes. The volatilization pollution caused by laxness makes personnel need to pay attention to the status of the test tubes on the test tube rack from time to time during use, which invisibly increases the care of the staff and leads to low efficiency in the use of chemical test tube racks. Therefore, it is easy to place test tubes that can solve such problems The realization of high school chemistry test tube rack is imperative
