chemical carrying case

Abstract

The invention discloses a chemical drug carrying box. The chemical drug carrying box comprises a box body, wherein a drawer is arranged at the lower part of the box body; a lifting handle is arranged above the box body; the middle part of the lifting hand is concave and wide and flat experiment tabletops are arranged at two ends of the lifting handle; a base is arranged on the experiment tabletop at one end of the lifting handle; a mounting groove is formed in the middle of the base; a motor, which is vertically arranged, is arranged in the mounting groove; a main shaft of the motor is fixedly provided with a connecting rod; the inner end of the connecting rod is connected with the main shaft of the motor; a sleeve is arranged at the outer end of the connecting rod; an annular groove, which takes the motor as the center, is formed in the upper surface of the base; the height of a bottom wall of the annular groove is smoothly increased along the circumferential direction and then is smoothly and gradually reduced; the orthographic projection of the sleeve on the upper surface of the base is located in the annular groove; a test tube rack is arranged on the experiment tabletop at the other end of the lifting handle; and an L-shaped hand-pushing handrail is arranged on one side of the lifting handle. The chemical drug carrying box has a function of storing drugs and teachers can do experiments by utilizing the chemical drug carrying box; and a condition that the drugs are carelessly splashed on a platform and teaching equipment is damaged is avoided.

Description

Technical field: [0001] The invention relates to a carrying case for chemicals. Background technique: [0002] Chemistry is a particularly abstract subject, and it is very beneficial to arrange more experiments and demonstrations in class to help students understand what they have learned in class in a timely manner. When it is determined that the basic chemical experiment will be carried out in the classroom during this class, the teacher must assign the students to carry the medicines and equipment needed for the experiment to the classroom before class. Since most chemical experiments require a lot of chemicals and glassware, and the glassware is easy to be damaged during the handling process, the liquid chemicals are not only easy to lose, but also sometimes cause damage to human skin, so generally All medicines are put into the carrying case, but the current carrying case is just a simple container of medicines, and chemical experiments are usually carried out on the p...

Problems solved by technology

Since most chemical experiments require a lot of chemicals and glassware, and the glassware is easy to be damaged during the handling process, the liquid chemicals are not only easy to lose, but also sometimes cause damage to human skin, so generally All medicines are put into the carrying case, but the current carrying case is just a simple container of medicines, and chemical experiments are usually carried out on the podium, and some corrosive chemicals are often used in the experiments. Be careful that it will splash on the podium and cause corrosion to teaching equipment
