A combined operating device for biochemical experiment teaching

Abstract

The invention relates to the technical field of teaching equipment, and discloses a combined operating equipment for biochemical experiment teaching, which includes a box body with an open top, a biological experiment platform is slidingly connected inside the box body, and both sides of the inner bottom of the box body are fixed A sleeve with an opening at the top is connected, and connecting rods are slidably connected inside the two sleeves, and the tops of the two connecting rods extend to the outside of the two sleeves respectively, and the tops of the two connecting rods are connected to the biological experiment platform The bottom is fixedly connected, and the side walls where the two connecting rods are far away from each other are provided with two card slots distributed up and down. The outer wall of the box body is provided with installation slots corresponding to the card slots. Corresponding to the locking mechanism, a first spring is fixedly connected between the bottom of the connecting rod and the inner bottom of the sleeve. The combined operating device for biochemical experiment teaching can reduce the space for placing a test bench and accommodate experimental instruments.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a combined operating equipment for biochemical experiment teaching. Background technique [0002] In the teaching process of biology or chemistry, it is often necessary to carry out biological experiments or chemical experiments so that students can further understand the knowledge they have learned. The existing biological experiments and chemical experiments in the teaching process are generally carried out on the experimental bench. However, the traditional experimental benches are often only suitable for biological experiments or chemical experiments. When biological experiments or chemical experiments are required, it is generally necessary to purchase experimental benches for biological experiments and chemical experiments for teaching experiments. The two experimental benches are not in use. Sometimes it is also placed separately, and the required placement spac...
