Problems solved by technology
[0002] Chemistry experiments are an important part of chemistry teaching. During the teaching of chemistry experiments, the stirring and drainage of solutions are often encountered. Usually, the practical drainage rod is used to drain the liquid substance into the container, and then the practical drainage rod is used to stir the liquid. Uniformity, however, the traditional drainage rod has a single structure and a small stirring area, and the solution cannot be stirred evenly and quickly fused during the stirring process

The invention discloses a guiding and stirring device for chemical teaching experiments. The guiding and stirring device comprises a fixed ring, wherein the side wall of one end of the fixed ring is glued with a connecting plate; the side wall of the lower end of the connecting plate is welded with a telescopic rod; the side wall of one end of the telescopic rod is provided with a push rod motor;a first spring is fixedly connected with the side wall of one end of the push rod motor, and the other end of the first spring is fixedly connected with a placing plate; the side wall of one end of the placing plate is rotatably connected with a connecting block through a rotating shaft; the side wall of one end of the connecting block is welded with a sleeving block; a connecting rod is arrangedin and sleeved by the sleeving block; the side wall of one end of the connecting rod is fixedly provided with a snapping plate through screws; the side wall of the bottom end of the snapping plate isrotatably connected with a vertical rod; the side wall of one end of the vertical rod is rotatably connected with a movable rod; the side wall of the bottom end of the movable rod is welded with a horizontal rod; the side wall of one end of the horizontal rod is rotatably connected with a sliding block; and the side wall of one end of the sliding block is slidably connected with a sliding rail. The guiding and stirring device of the invention is large in stirring area and fast in stirring; the functions of guiding and stirring can be used separately; and the angle of a guiding rod can be changed according to the guiding demands of chemical experiments.
Description
technical field [0001] The invention relates to the technical field of drainage and stirring devices, in particular to a drainage and stirring device for chemistry teaching experiments. Background technique [0002] Chemistry experiments are an important part of chemistry teaching. During the teaching of chemistry experiments, the stirring and drainage of solutions are often encountered. Usually, the practical drainage rod is used to drain the liquid substance into the container, and then the practical drainage rod is used to stir the liquid. Uniformity, however, the traditional drainage rod has a single structure and a small stirring area, so the solution cannot be stirred evenly and quickly fused during the stirring process. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a drainage stirring device for chemistry teaching experiments. [0004] In order to achieve the above object, the pres...
