Description

Technical Field

[0001] This application relates to the field of culture dish rack technology, specifically a culture dish rack for pharmaceutical testing. Background Technology

[0002] In pharmaceutical research, cell culture is commonly used to screen for drug activity and toxicity, as well as to assess cellular responses and expression of drugs. Microbial culture, on the other hand, is typically used to evaluate antibacterial efficacy, detect drug susceptibility, and identify bacterial strains. Culture dishes are important containers for both cell and microbial culture, supporting and promoting cell and microbial growth and differentiation while providing stable environmental parameters to ensure experimental reproducibility and accuracy. Therefore, culture dishes are very common and essential laboratory equipment in pharmaceutical testing, playing a crucial role in drug discovery, development, and quality control.

[0003] Petri dish racks are often used when petri dishes need to be stored. A common petri dish rack is a metal frame that can be used to stack multiple petri dishes to achieve a storage effect. However, this storage method is not very effective because it lacks effective fixation for individual petri dishes.

[0004] A search revealed a Chinese patent publication number CN217025971U, which discloses a cell culture dish rack. Although the device provides an individual placement space for each culture dish to ensure storage effectiveness, it still lacks a way to secure the culture dishes. Therefore, external shaking or impact can still cause relative movement between the culture dishes and the dish holder. In this case, there is a risk of collision or even detachment between the culture dishes and the dish holder, thus failing to guarantee the safety of the culture dishes after storage.

[0005] Chinese patent discloses a petri dish rack for pharmaceutical testing (authorization announcement number CN220116504U). The patented technology includes:

[0006] When storing the petri dish, you can open the lid by pressing the button, then place the petri dish inside the storage box and position it between the three elastic strips. The petri dish can then compress the three elastic strips, causing them to deform. The elastic force generated by the deformation of the elastic strips can hold the petri dish in place. After closing the lid, the petri dish can be stored in a sealed manner, which can ensure the stability of the petri dish after storage. Even if the device is shaken or impacted by the outside world, the elastic force of the elastic strips can also buffer and absorb shock for the petri dish, thus ensuring the safety of the petri dish after storage.

[0007] When using the petri dish, hold the handle and pull it. The handle, through the connecting rod, can pull the locking block and gear to separate. In this case, the support rod and the tray can rotate relative to each other. Therefore, while holding the handle, simply turn the handle to adjust the tilt of the tray. When the tray tilts the storage box outward, the storage box can be opened to take out the petri dish. During this process, pressing the button separates the protrusion from the fixing block, and the lid can tilt upward and open on its own under the elastic force of the torsion spring, which further facilitates the use of the petri dish.

[0008] However, it has certain drawbacks: because the position and deformation range of the elastic strip are fixed, when the size of the culture dish is too small, it cannot fully contact and squeeze the elastic strip, resulting in insufficient clamping force and the culture dish shaking in the box; when the size of the culture dish is too large, the elastic strip is overstretched and is prone to permanent deformation or even breakage, losing its clamping function. This adaptation mechanism is difficult to adapt to the stable storage needs of culture dishes of different sizes and there is a risk of damage. Utility Model Content

[0027] Please see Figure 1 and Figure 2 In this embodiment of the present invention, a culture dish rack for pharmaceutical testing includes a base plate 1. Two vertical plates 2 are symmetrically fixed to the upper surface of the base plate 1 in the front-back direction. Multiple horizontal plates 3 are fixed between the two vertical plates 2 from top to bottom. A culture dish storage box 4 is movably attached to the upper surface of the horizontal plates 3. A cover plate 5 is movably attached to the upper end of the culture dish storage box 4. A cover block 6 is fixed to the lower surface of the cover plate 5. The cover block 6 is located inside the culture dish storage box 4. An elastic sleeve 7 is fixedly sleeved on the outside of the cover block 6. The outer surface of the elastic sleeve 7 is movably attached to the inner side of the culture dish storage box 4.

[0028] The petri dishes are stored in petri dish storage box 4;

[0029] The cover plate 5 is larger in both length and width than the cover block 6;

[0030] The length and width of the elastic sleeve 7 in its natural, uncompressed state are greater than the corresponding length and width of the petri dish storage box 4. When the cover plate 5, together with the cover block 6 and the elastic sleeve 7, are pressed down into the petri dish storage box 4, the elastic sleeve 7 is subjected to radial compression from the inner wall of the petri dish storage box 4 and undergoes elastic deformation. An interference fit is formed between the elastic sleeve 7 and the inner wall of the petri dish storage box 4. The interference amount is preferably 0.5-2mm, thereby fixing the cover plate 5 to the petri dish storage box 4.

[0031] The elastic sleeve 7 is preferably made of rubber.

[0032] exist Figure 1 and Figure 2In the middle: The front and rear surfaces of the petri dish storage box 4 are provided with fixing mechanisms 8. The fixing mechanism 8 includes an L-shaped block 9. The horizontal section of the L-shaped block 9 is movably connected to a fixing bolt 10. The lower end of the fixing bolt 10 is threaded to the inside of the upper surface of the horizontal plate 3. The vertical section of the L-shaped block 9 is movably connected to a fixing bolt 21. One end of the fixing bolt 211 is threaded to the inside of one side surface of the petri dish storage box 4.

[0033] The petri dish storage box 4 can be easily assembled and disassembled using fixing bolts 10 and 11.

[0034] exist Figures 2-5 In the petri dish storage box 4, a stabilizing mechanism 12 is provided on the lower inner surface. The stabilizing mechanism 12 includes a U-shaped plate 13. The lower end of the U-shaped plate 13 is fixed to the left end of the lower inner surface of the petri dish storage box 4. A rotating rod 14 is rotatably connected through the upper surface of the U-shaped plate 13. A spur gear 15 is fixed to the lower end of the rotating rod 14. Both ends of the spur gear 15 are meshed with racks 16. The racks 16 are located inside the U-shaped plate 13. A slide rail 17 is slidably embedded in the lower surface of the rack 16 in the front-back direction. The lower end of the slide rail 17 is fixed to the lower inner surface of the petri dish storage box 4. A stabilizing plate 18 is fixed to one end of the rack 16. A stabilizing block 19 is fixed to the side surface of the stabilizing plate 18 near the rack 16. The upper surface of the U-shaped plate 13 and the... A positioning component 20 is provided on the outside of the rotating rod 14. The positioning component 20 includes an L-shaped plate 21. The vertical section of the L-shaped plate 21 is fixed to the upper surface of the U-shaped plate 13, and the L-shaped plate 21 is located to the right of the rotating rod 14. A screw 22 is threaded through the upper surface of the horizontal section of the L-shaped plate 21. A positioning plate 23 is rotatably connected to the lower end of the screw 22. Positioning rods 24 are fixed to the upper surface of the positioning plate 23 on both the front and rear sides of the screw 22. The positioning rods 24 move vertically through the horizontal section of the L-shaped plate 21. A face gear 25 is fixed to the left end of the positioning plate 23. The face gear 25 is movably sleeved on the outside of the rotating rod 14. A face gear 26 is meshed with the lower end of the face gear 25. The face gear 26 is fixedly sleeved on the outside of the rotating rod 14.

[0035] After the cover plate 5 is installed on the petri dish storage box 4, the cover block 6 does not contact the rotating rod 14;

[0036] The rotating rod 14 and the U-shaped plate 13 are rotatably connected by a bearing;

[0037] The slide rail 17 has a T-shaped cross section, and the lower surface of the rack 16 is provided with a T-shaped groove that matches the slide rail 17, ensuring that the rack 16 can only slide smoothly and linearly along the front and back direction of the slide rail 17, preventing the rack 16 from lifting, tilting or derailing during the movement.

[0038] The stabilizing block 19 is a component made of elastic material, preferably medical-grade silicone rubber or elastic polyurethane with a Shore A hardness of 30-50, and the opposing surfaces of the two stabilizing blocks 19 are both angular surfaces, which facilitates fitting the cylindrical culture dish.

[0039] The stabilizing block 19 is fixed to the stabilizing plate 18 by bolts and can be disassembled to facilitate the replacement of stabilizing blocks 19 with different clamping surface shapes;

[0040] Rotating the rotating rod 14 clockwise causes the spur gear 15 to drive the two racks 16 to move relative to each other, thereby bringing the two stabilizing blocks 19 closer together to hold the petri dish; rotating the rotating rod 14 counterclockwise causes the spur gear 15 to drive the two racks 16 to move away from each other, thereby causing the two stabilizing blocks 19 to separate.

[0041] The teeth of face gear 1 (25) face downwards, while the teeth of face gear 2 (26) face upwards.

[0042] Rotating the screw 22 can drive the positioning plate 23 to rise and fall. When the face gear 1 25 moves away from the face gear 26, the rotating rod 14 can rotate. When the face gear 1 25 meshes with the face gear 26, the rotating rod 14 cannot rotate, thereby locking the clamping position of the stabilizing block 19.

[0043] The working principle of this utility model is as follows: During operation, the culture dish is first placed inside the culture dish storage box 4. Then, the rotating rod 14 is rotated clockwise. The rotating rod 14 drives the spur gear 15 to rotate, which in turn drives the two racks 16 meshing with it to slide towards each other along the slide rail 17. The racks 16 push the stabilizing plate 18 and the stabilizing block 19 to move towards the center, and the stabilizing block 19 is used to self-adaptively clamp the culture dish. Then, the screw 22 is rotated, which causes the positioning plate 23 to drive the face gear 1 25 to descend until it is fully engaged with the face gear 26 fixed on the rotating rod 14, locking the rotating rod 14. Position 4 to ensure secure clamping; when the cover plate 5 is closed, the cover block 6, carrying the elastic sleeve 7, is pressed into the petri dish storage box 4. The cover plate 5 is fixed to the upper end of the storage box by the frictional force of the interference fit, and the cover block 6 does not contact the rotating rod 14; finally, place the petri dish storage box 4 on the horizontal plate 3, attach the L-shaped block 9 to the side wall of the storage box and the surface of the horizontal plate 3, use the fixing bolt 10 to pass through the horizontal section of the L-shaped block 9 and screw it into the threaded hole of the horizontal plate 3, and then use the fixing bolt 2 11 to pass through the vertical section of the L-shaped block 9 and screw it into the threaded hole of the side wall of the storage box. After tightening, the storage box can be quickly assembled and disassembled.
