[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, an embodiment of this utility model provides a test tube rack, which includes a support member 10, support feet 20, a fixing plate 30, and a support sleeve 40. The support feet 20 are fixedly connected to the bottom of the support member 10 in a divergent manner. The support member 10 is provided with a fixed core tube 13 and a movable core tube 14. The movable core tube 14 is sleeved inside the fixed core tube 13. The fixed core tube 13 and the movable core tube 14 are damped connected, and the movable core tube 14 slides along its own axis inside the fixed core tube 13. Multiple fixing plates 30 are provided and fixedly connected to the fixed core tube 13 and the movable core tube 14. Multiple test tube holes for placing test tubes are evenly distributed on the fixing plate 30. A support sleeve 40 is fixed inside the test tube hole. The support sleeve 40 is a cylindrical structure with openings at both ends and is an elastic element.

[0023] When the test tube rack is stored, the movable core tube 14 slides inside the fixed core tube 13. When the movable core tube 14 retracts into the fixed core tube 13, the fixing plate 30 on the movable core tube 14 and the fixing plate 30 on the fixed core tube 13 overlap, reducing the volume of the test tube rack. When using the test tube rack, the movable core tube 14 is pulled out, increasing the distance between the two fixing plates 30. The test tube is then placed into the support sleeve 40, where there is an interference fit between the test tube and the support sleeve 40. The support sleeve 40 can fix the test tube, allowing it to be suspended and fixed to the fixing plate 30. Thus, the double-layered fixing plate 30 can increase the number of test tubes that can be placed.

[0024] The test tube rack disclosed in this embodiment of the utility model uses a telescopic fixed core tube 13 and a movable core tube 14 to fix the fixed plate 30 respectively. When the test tube rack is not in use, the movable core tube 14 retracts into the fixed core tube 13, the distance between the two fixed plates 30 decreases, the volume of the test tube rack decreases, and the test tube rack is easy to store. When placing test tubes, the movable core tube 14 is pulled out, the distance between the two fixed plates 30 increases, and the test tubes can be placed inside the support sleeve 40 on the fixed plate 30.

[0025] Specifically, in this embodiment, such as Figure 3 As shown, the support member 10 also includes a base 11 and a fixing tube 12. The fixing tube 12 is tubular. The base 11 and the fixing tube 12 are fixedly connected. The support foot 20 is fixedly connected to the base 11. The fixing core tube 13 is fixedly connected to the fixing tube 12.

[0026] like Figure 6 As shown, the base 11 is a cylindrical structure, and a mounting groove 16 is provided on the base 11. The support foot 20 is fixed to the mounting groove 16. The mounting groove 16 is a square groove, and the support foot 20 is a square tube. The support foot 20 is fixed to the inner side of the mounting groove 16 by interference fit.

[0027] Preferably, the support foot 20 is provided with semi-cylindrical protrusions on both sides, and the mounting groove 16 is provided with a limiting groove 17 on the inner side. The limiting groove 17 is a semi-circular straight groove. The limiting groove 17 coincides with the semi-cylindrical protrusions on both sides of the support foot 20, so that the limiting groove 17 plays the role of limiting the support foot 20.

[0028] Preferably, there are three mounting slots 16, which are located at the end of the base 11 away from the fixing tube 12. There are three support feet 20, and the ends of the three support feet 20 are respectively fixed to the inside of one of the mounting slots 16.

[0029] Preferably, in this embodiment, one end of the fixed core tube 13 is fixed to the inside of the fixed tube 12, and a fastening sleeve 15 is provided at the end of the fixed core tube 13 away from the base 11. The fastening sleeve 15 is a rubber sleeve, and the fastening sleeve 15 is fixed to the fixed core tube 13 by interference fit. The inner diameter of the opening of the fastening sleeve 15 is smaller than the outer diameter of the movable core tube 14. When the movable core tube 14 is inserted into the fixed core tube 13, the fastening sleeve 15 clamps the movable core tube 14, thereby causing damped sliding between the fixed core tube 13 and the movable core tube 14.

[0030] Preferred, such as Figure 2As shown, the support leg 20 includes a fixed support leg 21, a movable support leg 22, and a support block 23. The fixed support leg 21 and the movable support leg 22 are square tubes. One end of the movable support leg 22 is located inside the fixed support leg 21. The fixed support leg 21 and the movable support leg 22 slide with damping. In this embodiment, both the fixed support leg 21 and the movable support leg 22 are plastic square tubes. The fixed support leg 21 and the movable support leg 22 are transitionally fitted, thereby providing damping for the support of the fixed support leg 21 and the movable support leg 22. The support block 23 is block-shaped, such as a square block or a trapezoidal block. The support block 23 is fixedly connected to the end of the movable support leg 22 away from the fixed support leg 21. The bottom surface of the support block 23 is flush with the bottom surface of the fixed support leg 21. The lengths of the fixed support leg 21 and the movable support leg 22 can be changed, thereby further reducing the volume of the placement rack.

[0031] Preferably, the fixing plate 30 is a fan-shaped plate, and the small end of the fixing plate 30 is sleeved on the fixed core tube 13 or the movable core tube 14. The fixing plate 30 and the fixed core tube 13 or the movable core tube 14 are fixedly connected by adhesive or interference fit. The fixing plate 30 can rotate around the fixed core tube 13 through the movable core tube 14, so that the two fixing plates 30 can overlap.

[0032] In this embodiment, multiple movable core tubes 14 are provided, and the inner diameters of the multiple movable core tubes 14 are different, so that the multiple movable core tubes 14 form a sleeve structure. A fastening sleeve 15 is provided at the end of each movable core tube 14, and the fastening sleeve 15 is used to fix the inner movable core tube 14.

[0033] like Figure 4 and Figure 5 As shown, the support sleeve 40 is a rubber tube structure, and a limiting ring groove 41 is provided on the outer side of the support sleeve 40. The limiting ring groove 41 is stuck in the test tube hole.
