Test tube oscillation device for chemistry teaching

Abstract

The invention discloses a test tube oscillation device for chemistry teaching. The device comprises a base, a sliding groove is formed in the top of the base. A connecting plate is slidably connectedbetween the inner walls of the two opposite sides of the sliding groove. A plurality of first springs are fixedly connected between the bottom of the connecting plate and the inner bottom of the sliding groove. The top of the connecting plate is fixedly connected with a mounting plate; the front surface of the mounting plate is fixedly connected with a plurality of placing clamping blocks which are arranged in the same horizontal direction; and test tubes are placed in the grooves in the tops of the multiple placing clamping blocks, clamping mechanisms are arranged on the outer walls of the two sides of each test tube, and a plurality of first mounting grooves which are formed in the same horizontal direction are formed in the positions, located over the multiple test tubes, of the front face of the mounting plate. The test tube oscillation device is reasonable in structural design, the test tube can be effectively limited and clamped, medicines in the test tube can be shaken and shaken up, manual shaking of the medicines in the test tube is omitted, and the workload of experimenters is reduced.

Description

technical field [0001] The invention relates to the technical field of teaching supplies, in particular to a test tube oscillation device for chemistry teaching. Background technique [0002] Chemistry is one of the important basic sciences. It has developed rapidly in the interpenetration with physics, biology, geography, astronomy and other disciplines, and has also promoted the development of other disciplines and technologies. [0003] In chemistry teaching, it is often necessary to vibrate and shake the test tube, and the existing way of shaking and shaking is usually to shake the medicine in the test tube manually, the operation is complicated, and the long-term shaking will cause the experimenter's arm to shake. Soreness, and in the shaking process, the test tube is easy to fall off from the experimenter's hand, which has certain safety hazards. For this reason, we have designed a test tube shaking device for chemistry teaching to solve the above problems. Contents ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of shaking the medicine in the test tube manually by shaking the medicine in the test tube in the prior art. During the process, the test tube is easy to fall off from the hands of the experimenter, and there is a certain potential safety hazard. However, a test tube oscillation device for chemistry teaching is proposed, which can effectively limit and clamp the test tube and control the vibration of the test tube. The drug is shaken and shaken, eliminating the need to manually shake the drug in the test tube, reducing the workload of the experimenter
