Novel laboratory bench and operation method

Abstract

The invention discloses a novel laboratory bench and an operation method in the technical field of laboratory benches. The laboratory bench includes a box-shaped frame, a base is mounted at the bottomof an inner chamber of the box-shaped frame, a scissor-type lifting bracket is arranged at the top of the base through a lower fixing block and a lower sliding block, an upper fixing block and an upper sliding block are respectively arranged at the tops on the left and right sides of the scissor-type lifting bracket, U-shaped fixing plates are installed on both inner walls of the box-shaped frame, energy-storing clockwork devices are mounted at the tops of the U-shaped fixing plates, rotary rope storage rotating shafts are fixedly installed at the ends of power shaft levers of the energy-storing clockwork devices, moving cover plates are installed at the tops on the left and right sides of the box-shaped frame, and the bottoms of the moving cover plates are connected with circumferentialracks of the energy-storing clockwork devices. When a laboratory bench plate rises, the moving cover plates are opened, so that the moving cover plates and the laboratory bench plate form a large laboratory bench; meanwhile, when the laboratory bench plate declines, the moving cover plates are closed to prevent dust in the air from contaminating the laboratory bench plate.

Description

technical field [0001] The invention relates to the technical field of test benches, in particular to a novel test bench and an operation method. Background technique [0002] Chemistry is a scientific subject that attaches great importance to experimental practice. Many schools do not have or have small laboratories. In chemistry class, it is difficult for students to master the knowledge points of chemical experiments. They can only think through their brains. It affects the students' impression of learning knowledge, and at the same time affects the school's enrollment rate. In order to improve the teaching quality and enrollment rate of chemical experiments, schools are constantly strengthening the laboratory construction. With the development of science and technology and the progress of society, the school's In order to compete with each other, the chemical experiment equipment of our high school students also needs to be updated, and the existing chemical experiment b...

Problems solved by technology

[0003] The purpose of the present invention is to provide a new type of experimental bench and operation method, to solve the above-mentioned background technology that cannot move back and forth between the classroom and the laboratory, and if the experimental bench teaches, there are many articles stored, and the general experimental bench The countertop is small and cannot meet the demand, and the chemical countertop is easily polluted by dust in the air
