Example Embodiment

[0019] 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.

[0020] See Figure 1-4 , The present invention provides an embodiment: a test tube rack for chemistry teaching, including a base 1, a dual-axis motor 17 (model Y90S-6-1.1) is provided on one side above the base 1, and two ends of the dual-axis motor 17 The first runner 7 and the second runner 18 are respectively installed on the output shaft. The first slide rail 2 is installed on the upper end of the base 1, and the first slide rail 2 is...

Abstract

The invention discloses a test tube stand for chemical teaching. The test tube stand for chemical teaching comprises a base, a double-shaft motor is arranged on one side above the base, and a first rotary wheel and a second rotary wheel are mounted at the output shafts at the two ends of the double-shaft motors. Fixing claws are pushed to make a third sliding block to slide in a third sliderail, accordingly the distance between the fixing claws is adjusted, and thus containers with different sizes are fixed. According to the test tube stand for chemical teaching, the double-shaft motor drivesthe first rotary wheel and the second rotary wheel to rotate, meanwhile the first rotary wheel pulls a first sliding block to conduct reciprocating sliding in a first sliderail through a first connection rod, accordingly a first placing table conducts reciprocating movement, the second rotary wheel pulls a second sliding block to conduct reciprocating sliding in a second sliderail through a secondconnection rod, accordingly a second placing table conducts reciprocating movement, the first placing table and the second placing table are shaken conveniently, and thus the experimental effect is rapider and better.

Description

technical field [0001] The invention relates to the field of chemistry teaching equipment, in particular to a test tube rack for chemistry teaching. Background technique [0002] Chemistry is a natural science based on experiments. The word "chemistry" literally means "the science of change". Therefore, volumetric flasks, round bottom flasks, separating funnels, long-necked funnels, condensation Tubes, Erlenmeyer flasks, beakers, measuring cylinders, acid-base burettes, test tubes and other glassware, and in the process of chemistry teaching, in order to facilitate the extraction of reaction samples, test tubes are often used, and in order to fix the test tubes for easy inspection, multiple test tubes are usually used Place on test tube stand. [0003] The existing test tube rack has a simple structure and a single style, and cannot fix vessels of different sizes, and it is very inconvenient to manually vibrate the existing test tube rack during the experiment, so that bett...
