Anti-skid reagent bottle for teaching experiments

Abstract

The invention discloses an anti-skid reagent bottle for teaching experiments. The anti-skid reagent bottle comprises a reagent bottle body. The top end and the bottom end of the reagent bottle body are spirally connected to a reagent bottle cover and a protecting base separately; a rubber sleeve ring and a label clip symmetrically sleeve on the reagent bottle body relative to the horizontal center line; a scaleplate is sprayed to the vertical center line of the reagent bottle body; the label clip is formed by rotatably connecting a bottle body fixing rack to a label fixing body through a rotary connecting shaft; the other ends of the bottle body fixing rack and the label fixing rack are fixedly connected by a fixed clip; a transparent window is formed in the center of a shell in front of the label fixing rack; and a telescopic supporting spring is connected to the upper surface wall in the reagent bottle cover through a connecting rod. According to the anti-skid reagent bottle disclosed by the invention, the rubber sleeve ring is arranged first, so that the reagent bottle clip clamps the anti-skid reagent bottle for teaching experiments more stably to prevent the reagent bottle from falling to be broken.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a non-slip reagent bottle for teaching experiments. Background technique [0002] Reagent bottles are divided into wide-mouth and narrow-mouth; ground-mouth and non-ground-mouth, etc. Wide-mouth bottles are used to hold solid reagents, and narrow-mouth bottles are used to hold liquid reagents; brown bottles are used for reagents that are protected from light. To prevent moisture absorption and concentration changes of reagents, non-slip reagent bottles for teaching experiments are used as one of the common experimental equipment in high school chemistry experiment teaching, and can be applied to the storage and reaction of reagents for various chemical experiments. [0003] The structure of the traditional non-slip reagent bottle for teaching experiments is relatively simple, and it is safe to use, and it is prone to information that the clamping is not stable enough, and i...

Problems solved by technology

[0003] The structure of the traditional non-slip reagent bottle for teaching experiments is relatively simple, and it is safe to use, and it is prone to information that the clamping is not stable enough, and if it is used for a long time, the label will fall off, or the label will be damp and cause the writing to be unclear. As a result, it is impossible to distinguish, resulting in waste of reagents
