Multipurpose chemical experiment instrument support

Abstract

The invention belongs to the technical field of teaching experiment instrument equipment, and relates to a multipurpose chemical experiment instrument support. The support comprises a box body, a water tank is fixedly connected to the surface of the box body, a water pump is fixedly connected to the upper surface of the water tank, a water inflow pipe of the water pump penetrates through the surface of the water tank, and a first connecting pipe is fixedly connected to the surface of a water outflow pipe of the water pump. According to the multipurpose chemical experiment instrument support, a motor, a first gear, a rack and a first fan-shaped tooth are adopted; when the inner wall of a test tube is cleaned, people control the motor to run through a control switch, so that a fourth gear, a third gear, a second gear and the first gear are driven to rotate at the same time, and meanwhile the first fan-shaped tooth and a second fan-shaped tooth are driven to rotate, so that the rack and a fixing table are driven to reciprocate up and down; the fixing table moves up and down to drive a brush to move up and down to brush the inner wall of the test tube; and under the action of the motor, the first gear, the rack and first fan-shaped tooth, the cleaning efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of teaching experiment instruments and equipment, and in particular relates to a multipurpose chemical experiment instrument support. Background technique [0002] The instruments used in chemical experiments are called chemical instruments. Materials can be metered or reacted. It is mainly divided into measuring instruments and reaction instruments. The instruments are combined in a specific way to form a device to achieve the purpose of the experiment. Glass instruments such as test tubes, beakers, and flasks are commonly used in chemical experiments, which are usually fragile and placed directly on the table. Or it is easy to slip and break in the instrument cabinet, especially the easy-to-roll glass instruments such as test tubes and flasks, which are difficult to fix and place. The chemical instrument bracket is used to place the above-mentioned glass instruments, and the glass instruments need to be c...

It is mainly divided into measuring instruments and reaction instruments. The instruments are combined in a specific way to form a device to achieve the purpose of the experiment. Glass instruments such as test tubes, beakers, and flasks are commonly used in chemical experiments, which are usually fragile and placed directly on the table. Or it is easy to slip and break in the instrument cabinet, especially the easy-to-roll glass instruments such as test tubes and flasks, which are difficult to fix and place. The chemical instrument bracket is used to place the above-mentioned glass instruments, and the glass instruments need to be cleaned after use. It is manually cleaned with a brush at a nearby water source, and only one test tube can be cleaned each time, which is inefficient and cumbersome to operate
