The surface of column 3 is slidably connected to the inner cavity of the circular hole 9. The surfaces of the two L-shaped plates 5 with openings are slidably connected to the upper and lower sides of the inner cavity of the cross-shaped groove 4, respectively. The surface of the L-shaped plate 5 with openings is slidably connected to the inner cavity of the rectangular hole 10. The surface of the trapezoidal rectangular rod 12 is slidably connected to the inner cavity of the cross-shaped groove 4. Guide grooves 13 are provided on both the upper and lower sides of the trapezoidal rectangular rod 12. Limiting strips 14 are welded on both the upper and lower sides of the inner cavity of the rectangular frame 11. The surface of the limiting strips 14 is slidably connected to the inner cavity of the guide grooves 13. Through the cooperation of the trapezoidal limiting strips 14 and the guide grooves 13, the trapezoidal rectangular rod 12 can obtain lateral guiding force during the sliding process in the inner cavity of the rectangular frame 11, so that the trapezoidal rectangular rod 12 can achieve a limiting effect, so that the trapezoidal rectangular rod 12 can avoid skewing when it slides.

[0026] Example 2:

[0027] Figure 1-5This invention illustrates a modular experimental table according to an embodiment of the present invention, comprising: hollow components 2 welded to the left and right sides of the experimental table 1 and slotted cylinders 3; the hollow components 2 have cross-shaped grooves 4 in their inner cavities; two perforated L-shaped plates 5 are welded to the left and right sides of the experimental table 1, respectively located on the upper and lower sides of the hollow components 2; round rods 6 are slidably connected to the inner cavities of the two perforated L-shaped plates 5; inclined blocks 7 are welded to the opposite ends of the two round rods 6; springs 8 are welded between the inclined blocks 7 and the perforated L-shaped plates 5; round holes 9 are formed on the surface of the hollow components 2, and the inner cavities of the round holes 9 communicate with the cross-shaped grooves 4; the slotted cylinders 3 are located on the upper and lower sides of the hollow components 2. Rectangular holes 10 are provided on both sides. Rectangular frames 11 are welded to both the left and right sides of the experimental table 1. A trapezoidal rectangular rod 12 is slidably connected to the inner cavity of the rectangular frame 11. A rubber pad 15 is fitted on the end of the trapezoidal rectangular rod 12 opposite to the rectangular frame 11. The rubber pad 15 can provide cushioning protection between the student's or teacher's hand and the end of the trapezoidal rectangular rod 12 when the student or teacher slides it, making it more labor-saving.

Universal wheels 18 are installed at the bottom of the experimental table 1.

[0028] Working Principle: In use, the user pushes the experimental table 1 to slide laterally relative to the experimental table 2, causing the slotted cylinder 3 to slide through the circular hole 9 into the inner cavity of the hollow part 2. Then, under the action of the inclined plane 17, the slotted cylinder 3 pushes the two inclined blocks 7 to slide back-to-back until the position of the rectangular hole 10 aligns with the inclined blocks 7. At this point, the rebound force of the spring 8 pushes the inclined blocks 7 back to their original position and slides into the inner cavity of the rectangular hole 10, thereby limiting the slotted cylinder 3 and achieving a fixed effect between the experimental table 1 and the experimental table 2. When restoring the position of the experimental table 1, press the rubber pads 15 on both sides at the same time, and then push the trapezoidal rectangular rod 12 to slide into the inner cavity of the cross-shaped groove 4. Under the special shape of the trapezoidal rectangular rod 12, push the two inclined blocks 7 to slide back and forth again and get out of the inner cavity of the rectangular hole 10, so as to end the position restriction on the slotted cylinder 3, and then separate the experimental table 1 from the experimental table 1. This allows the experimental table to be fixed after being horizontally spliced ​​when students conduct group experiments, so that students can be safer when conducting experiments.

[0029] In summary, this modular experimental table, by pushing the experimental table 1 to slide laterally relative to the experimental table 1, and allowing the slotted cylinder 3 to slide into the inner cavity of the hollow part 2, and then the inclined block 7 to limit the slotted cylinder 3, achieves a fixing effect between the experimental table 1 and the experimental table 2. This achieves the purpose of making the experimental table fixed after being horizontally assembled when students are conducting group experiments, thus making the experimental operation safer for students.
