A mounting cylinder 11 is fixedly installed on the bottom side of the experimental flat plate 4, and a cylinder groove 12 is provided on the mounting cylinder 11. A limit column 15 is installed in the cylinder groove 12 through an elastic connection mechanism. The elastic connection mechanism includes a connecting member 13 and a spring 14. A connecting member 13 is movably installed in the cylinder groove 12, and the connecting member 13 is fixedly connected to the limit column 15. One end of the spring 14 is fixedly installed on the bottom side of the connecting member 13, and the other end of the spring 14 is fixedly installed on the bottom inner wall of the cylinder groove 12. The limit column 15 can be adjusted up and down through the elastic connection mechanism; one end of the limit column 15 movably extends into the rotating groove 8 and is inserted into the corresponding limit groove 10. A plurality of universal wheels 18 are provided on the bottom side of the experimental table main body 1.
[0021] Furthermore, a plurality of limit grooves 10 are distributed in a circular array, and the limit grooves 10 are located on the outer side of the circular rotating plate 9. When the limit column 15 is inserted upward into the limit groove 10 corresponding to the bottom side of the circular rotating plate 9, the position of the circular rotating plate 9 after rotation is fixed.
[0022] Furthermore, two side grooves 16 are provided on both sides of the experimental tablet 4 , and the two side grooves 16 are symmetrically arranged, so that the teacher can conveniently adjust the experimental tablet 4 upward by holding the two side grooves 16 on the experimental tablet 4 .
[0023] Furthermore, a table groove 17 is opened on the experimental table body 1, and the cross-sectional dimension value of the table groove 17 is slightly larger than the cross-sectional dimension value of the mounting tube 11, so that when the experimental plate 4 is attached to the top side of the experimental table body 1, the mounting tube 11 on the bottom side of the experimental plate 4 is inserted into the table groove 17.
[0024] Furthermore, multiple universal wheels 18 are respectively located at the four corners of the bottom side of the laboratory bench main body 1. The universal wheels 18 have a self-locking function. By pushing the laboratory bench main body 1, under the action of the multiple universal wheels 18, the experimental instruments placed on the laboratory bench main body 1 are moved and displayed in the laboratory. At the same time, the universal wheels 18 have a self-locking function. When the laboratory bench main body 1 is moved to a designated location, the laboratory bench main body 1 can be fixed in place at any time.
[0025] When in use: During laboratory teaching, when it is necessary to adjust the display height of the experimental table body 1, the teacher holds the two side grooves 16 on the experimental flat plate 4 and drives the experimental flat plate 4 upward to move the movable frame 3 upward in the movable groove 2. When the experimental flat plate 4 rises to a suitable height, the plug plate 7 is inserted into the corresponding through hole 6 and the frame mouth 5 to complete the limit fixation of the height position of the movable frame 3 and the experimental flat plate 4. When displaying the experimental instrument, the teacher places the experimental instrument on the circular rotating plate 9, presses the connecting piece 13 downward, drives the limit column 15 to move into the barrel groove 12, and at this time the spring 14 is deformed and compressed by the force, and then the through hole 5 is pressed. By adjusting the circular rotating plate 9 to rotate in the rotating groove 8, the experimental instruments on the circular rotating plate 9 are driven to rotate, which is convenient for students to observe the experimental instruments on the circular rotating plate 9 in an all-round manner during laboratory teaching. When it is necessary to fix the position of the circular rotating plate 9 after rotation, the connecting piece 13 is loosened, and under the elastic force of the spring 14, the connecting piece 13 drives the limiting column 15 to be inserted upward into the limiting groove 10 corresponding to the bottom side of the circular rotating plate 9, thereby fixing the position of the circular rotating plate 9 after rotation. By pushing the experimental table main body 1, under the action of multiple universal wheels 18, the experimental instruments placed on the experimental table main body 1 are driven to be moved and displayed in the laboratory.
[0026] In summary, by adjusting the experimental plate 4 to move upward, and then inserting the plug plate 7 into the corresponding through-hole 6 and the rack opening 5, the experimental instruments placed on the experimental plate 4 are fixed after height adjustment, and the display height of the experimental instruments on the experimental table main body 1 is adjusted, which is convenient for displaying to students of different heights during laboratory teaching. At the same time, after adjusting the connecting piece 13 and the limit column 15 downward by the elastic connection mechanism, it is convenient to adjust the circular rotating plate 9 to rotate in the rotating groove 8, thereby driving the experimental instruments on the circular rotating plate 9 to rotate, which is convenient for students to observe the experimental instruments on the circular rotating plate 9 in an all-round manner during laboratory teaching. By pushing the experimental table main body 1, under the action of multiple universal wheels 18, the experimental instruments placed on the experimental table main body 1 are driven to move and display in the laboratory, which is convenient for students to observe the experimental instruments displayed on the experimental table main body 1 in an all-round manner during laboratory teaching. The method in this case does not require teachers to take experimental instruments for walking and display, which is more labor-saving.
