[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides a support for laboratory experimental operation, including a base plate 1. The upper end of the base plate 1 is provided with a plurality of bottom rings 9 and a top ring 10, and the top ring 10 is located above the bottom rings 9. The inner walls of the top ring 10 and the bottom rings 9 are provided with a second slot 12. The second slot 12 is provided with a second spring, and one end of the second spring is provided with a second block 11.

[0026] The bottom ring 9 has multiple positioning grooves 13 around its periphery, and multiple third slots are provided on the inner wall of the positioning grooves 13. The lower end of the top ring 10 has multiple vertical rods 14 that are inserted into the positioning grooves 13. The vertical rods 14 have multiple third cavities 16 inside, and a third spring is provided inside the third cavity 16. One end of the third spring has a third locking block 15 that cooperates with the third slot.

[0027] Overall structure and initial state: The support for this experiment mainly consists of a base plate 1, a bottom ring 9, a top ring 10, a support rod 4, various slots, cavities, blocks, and springs. In the initial state, the vertical rod 14 is inserted into the positioning slot 13 of the bottom ring 9, and the support rod 4 is stored in the slots 2 on both sides of the base plate 1.

[0028] The working principle for adapting to test tubes of different diameters is as follows: When a test tube needs to be placed, it is inserted through the top ring 10 into the bottom ring 9. During insertion, the outer wall of the test tube contacts and presses against the second locking block 11, which in turn compresses the second spring. Since the second spring has a certain elastic deformation range, test tubes of different diameters exert different degrees of pressure on the second locking block 11, resulting in corresponding different degrees of deformation of the second spring. This allows the top ring 10 and bottom ring 9 to limit the test tube's position according to its diameter via the second locking block 11, thus adapting to test tubes of different diameters.

[0029] Working principle for adapting to test tubes of different heights: To adjust the height of the top ring 10 to accommodate test tubes of different heights, the top ring 10 can be pulled. The vertical rod 14 at the lower end of the top ring 10 is inserted into the positioning groove 13 of the bottom ring 9. One end of the third spring inside the vertical rod 14 is connected to the third locking block 15, and the inner wall of the positioning groove 13 is provided with a third locking slot. When the top ring 10 is pulled, the third locking block 15 will cooperate with the third locking slot under the action of the third spring. When the top ring 10 is pulled to a suitable height, the third locking block 15 will be locked into the third locking slot of the corresponding height under the elastic force of the third spring, thereby fixing the position of the top ring 10 and achieving the limitation of test tubes of different heights.

[0030] In this embodiment, the base plate 1 has multiple slots 2 on both sides, and a support rod 4 is pulled out and installed in the slots 2.

[0031] In this embodiment, a limiting groove 5 is provided on the inner side of the empty groove 2, and a limiting block 6 is provided on one side of the support rod 4 to slide in cooperation with the limiting groove 5.

[0032] In this embodiment, the inner wall of the slot 2 is provided with a plurality of first slots 3, and the other side of the support rod 4 is provided with a plurality of first cavities 7. A first spring is provided in the first cavity 7, and a first block 8 that cooperates with the first cavity 7 is provided at one end of the first spring.

[0033] The operating principle of the support rod 4: The base plate 1 has slots 2 on both sides, allowing the support rod 4 to be pulled out within these slots. A limiting groove 5 is located inside the slot 2, and a limiting block 6 on one side of the support rod 4 slides into the limiting groove 5. This design ensures the support rod 4 remains stable during pulling, preventing wobbling or deviation. Simultaneously, a first locking groove 3 is located on the inner wall of the slot 2, and a first spring is located in the first cavity 7 on the other side of the support rod 4. A first locking block 8 at one end of the first spring engages with the first locking groove 3. When the support rod 4 needs to be pulled out, the spring force of the first spring is overcome, causing the first locking block 8 to disengage from the first locking groove 3, thus pulling the support rod 4 out. When the support rod 4 needs to be stored, pushing the support rod 4 causes the first locking block 8 to engage with the first locking groove 3 under the action of the first spring, achieving fixed storage of the support rod 4 within the slot 2.

[0034] In this embodiment, the first card block 8, the second card block 11, and the third card block 15 are all isosceles trapezoidal structures.

[0035] The function of the locking block structure: The first locking block 8, the second locking block 11, and the third locking block 15 are all isosceles trapezoidal structures. The advantage of this structure is that when the locking blocks engage with the slots, the hypotenuse of the isosceles trapezoid allows the blocks to slide more smoothly into or out of the slots under external force. During test tube placement and height adjustment of the top ring 10, the locking blocks can more flexibly engage and disengage from the slots, making operation more convenient.

[0036] In this embodiment, the outer wall of the top ring 10 is provided with anti-slip texture.

[0037] The function of the anti-slip texture: The anti-slip texture set on the outer wall of the top ring 10 increases the friction between the operator's hand and the top ring 10. When pulling the top ring 10 to adjust the height or placing and picking up test tubes, it can effectively prevent the hand from slipping, making the operation more stable and reliable.
