[0035] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1 to 4As shown, this embodiment proposes a laboratory workbench for teaching and demonstration, including an experimental table 1, a supporting table 2, an operating table 3, a display box 4, a positioning plate 5 and a positioning component. A plurality of dividing lines are provided on the experimental table 1 to facilitate the separation of the experimental teaching area, so as to facilitate the partitioned experimental teaching display for multiple students. The supporting table 2 is fixedly connected to the bottom end of the experimental table 1, and the operating table 3 is arranged between the supporting table 2 and the experimental table 1. An operating slot is provided on the operating table 3 to facilitate the placement of experimental supplies for teaching teachers. A hollow opening is provided between the experimental table 1 and the supporting table 2, and a hollow opening is provided A support column 15 is provided, which is fixedly connected to the operating table 3 to facilitate stable support of the operating table 3. The display box 4 is rotatably set on the top of the experimental table 1 through an adjusting component. The bottom end of the display box 4 is fixedly connected with an anti-wear pad 16 to prevent the display box 4 from being worn against the experimental table 1 when rotating on the experimental table 1. Two positioning plates 5 are provided, and the two positioning plates 5 are slidingly set in the display box 4. A positioning component is set on each positioning plate 5. A plurality of placement slots are opened on the support table 2, and the plurality of placement slots are arranged in a circular array, which is convenient for placing experimental items of multiple students.

[0037] The top of the rotating plate 13 is fixedly connected to the rotating handle 14, which can stably rotate the rotating shaft. The adjusting cylinder 6 is fixedly connected to the rotating shaft, and the adjusting rod 7 is slidably connected to the adjusting cylinder 6. The adjusting rod 7 is fixedly connected to the display box 4. A plurality of limit blocks 12 are arranged in a circumferential array on the adjusting rod 7. The adjusting cylinder 6 is provided with a limit groove for the limit block 12 to slide, which is convenient for limiting the sliding of the adjusting rod 7 in the adjusting cylinder 6. At the same time, through the cooperation of the plurality of limit blocks 12 and the plurality of limit grooves, the adjusting cylinder 6 can drive the adjusting rod 7 to rotate stably. A pull ring 17 is fixedly connected to one side of the display box 4 for pulling the display box 4, so as to adjust the position of the display box 4 through the cooperation of the adjusting cylinder 6 and the adjusting rod 7.

[0038] By pulling the display box 4 through the pull ring 17, the display box 4 can drive the adjusting rod 7 to move. When the adjusting rod 7 moves in the adjusting cylinder 6, the position of the display box 4 can be adjusted to facilitate students to place and take out experimental samples. At the same time, by rotating the rotating plate 13 with the turning handle 14, the rotating plate 13 can drive the rotating shaft to rotate, so that the rotating shaft drives the display box 4 to rotate through the adjusting cylinder 6 and the adjusting rod 7, thereby rotating the experimental samples, and then facilitating the experimental samples to be close to the students at different positions for students to observe and practice. At the same time, the experimental samples made by different students can be rotated in front of the teacher for comments, and different students can observe and learn from each other's experimental samples.

[0039] Specifically, the positioning assembly includes a positioning cylinder 8, a positioning rod 9, a compression spring 10 and a positioning bar 11. Two positioning cylinders 8 are provided, and the two positioning cylinders 8 are symmetrically connected to the display box 4. The positioning rod 9 is slidably connected between each positioning cylinder 8 and the display box 4, and the positioning rod 9 is fixedly connected to the positioning plate 5. The compression spring 10 is fixedly connected between the positioning rod 9 and the adjacent positioning cylinder 8. The positioning bar 11 is connected to the positioning rod 9, and a positioning groove for the positioning bar 11 to slide is opened on the positioning cylinder 8, which can limit the sliding of the positioning rod 9 in the positioning cylinder 8.

[0040] When the experimental sample is placed in the display box 4, the multiple positioning rods 9 will move in the multiple positioning cylinders 8 respectively through the multiple compression springs 10, so as to make the two positioning plates 5 close to each other, so that the two positioning plates 5 can clamp and position experimental samples of different specifications, thereby facilitating the improvement of the stability of experimental display teaching of the experimental samples.

[0041] In this embodiment, when the teaching teacher places the experimental sample in the display box 4, the two positioning plates 5 will approach each other to clamp and position the experimental sample. When it is necessary to conduct teaching demonstrations to multiple students in sequence, the teaching teacher can rotate the rotating plate 13 by turning the handle 14 to make the rotating shaft rotate the adjusting cylinder 6, and the adjusting cylinder 6 can drive the adjusting rod 7 and the display box 4 to rotate, so as to rotate the experimental sample. When the experimental sample rotates in front of the student, the student can pull the pull ring 17 to pull the display box 4 in front of him to observe and study the experimental sample. At the same time, the student can also place his own experimental sample in the display box 4 for other students to observe and study.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
