Problems solved by technology
[0003] In high school science learning, physical experiments and chemical experiments need to be carried out frequently. However, most of the existing experimental consoles are only designed for one subject, and the structure of the experimental console is simple, which cannot meet the teaching needs. At the same time, the school not only needs to purchase Two kinds of experimental operation equipment, and need to set up multiple experimental classrooms, not only increases the teaching cost, but also takes up resources, so we design a combined experimental operation equipment for science teaching to solve the above problems

The invention discloses a combined experimental operation device for science teaching. The combined experimental operation device comprises an experiment table main body, wherein one side of a desktopboard of the experiment table main body is provided with a cleaning water tank, the portion, at one end of the experiment table main body, is provided with two rotating seats, the rotating seats arerotatably connected with sliders, the two sliders are movably connected to the movable desktop board, two sides of the movable desktop board are symmetrically provided with sliding rails along the sides thereof, the movable desktop board is movably connected to the two sliders through two sliding rails, and the side edge of the desktop board, at one side of the cleaning water tank, of the experimental table main body is provided with a receiving groove in the longitudinal direction. In the invention, physical experiments and chemical experiments can be operated on the same operation platform,and operation platforms used in two experimental disciplines are combined, thereby not only reducing the purchase cost, but also simplifying the setting of an experimental classroom, bringing convenience for users to freely switch between the experimental operation platforms of the two disciplines and improving the operation convenience of users.
Description
technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a combined experimental operation equipment for science teaching. Background technique [0002] Experimental instruments are instruments used in specific experiments in natural sciences, mainly in physics, chemistry, and biology (including chemical instruments). Modern commonly used experimental instruments include test tubes, beakers, evaporating dishes, crucibles, alcohol lamps, Buchner funnels, gas washing bottles, drying tubes, tray balances, measuring cylinders, volumetric bottles, burettes, measuring devices, etc. There are nearly 700 major enterprises in the laboratory instrument industry, with laboratory centrifuges, balances, thermal analysis instruments, dynamic testing instruments, vacuum instruments and devices, electrophoresis instruments, casting testing instruments, strain measuring instruments, environmental testing equipment, and geotechnical testing i...
