[0030] The following will be combined with the drawings in 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.

[0031] Reference Figure 1The utility model provides an embodiment: a cell culture rack for placing cell culture tubes, including a bottom plate 1, which plays a supporting role and is used to improve the stability of the equipment. A culture rack 2 is provided on the top of the bottom plate 1, which is used to support the culture tube 4. The tops of the left and right sides of the culture rack 2 are fixedly connected with fixed plates 13 for facilitating the movement of the culture rack 2 and the control board 9. A limiting mechanism is provided inside the bottom plate 1, and a vertically arranged mounting column 3 is fixedly connected to the bottom of the inner wall of the culture rack 2. The number of the mounting columns 3 is set to multiple, and the multiple mounting columns 3 are arranged in a straight line and at equal intervals inside the culture rack 2. The mounting columns 3 are used to support the culture tube 4, and a culture mechanism is provided inside the mounting columns 3.

[0032] Reference Figure 1 、 Figure 3 The culture mechanism includes a culture tube 4, and the number of the culture tubes 4 is set to be multiple, and the number of the multiple culture tubes 4 is equal to the number of the mounting columns 3. By setting multiple culture tubes 4, multiple control groups can be set for cell culture, which facilitates the work of cell culture. The top of the circular surface of the culture tube 4 is fixedly connected with a side ring 5, and a slot 6 is provided inside the mounting column 3. The culture tube 4 is inserted into the inner wall of the slot 6, and a fastening ring 7 is fixedly connected to the inner wall of the mounting column 3. The fastening ring 7 is made of rubber material. The fastening ring 7 is used to increase friction and improve the stability of the culture tube 4 placed inside the mounting column 3. The surface of the fastening ring 7 contacts the outer wall of the culture tube 4. The surface of the mounting column 3 is provided with a through groove 8 for observing the internal state of the culture tube 4. The interior of the culture rack 2 is provided with a control mechanism.

[0033] Reference Figure 1 、 Figure 2 The control mechanism includes a control plate 9, a slide groove 10, a spacer block 11, and a curved surface 12. The slide groove 10 is opened on the surface of the culture rack 2, and the control plate 9 is arranged in a horizontal state. The control plate 9 is slidably installed on the inner wall of the slide groove 10. The sliding direction of the control plate 9 is up and down. The spacer block 11 is fixedly installed on the upper and lower surfaces of the control plate 9. The projection surface of the side ring 5 and the projection surface of the spacer block 11 have an overlapping part. When the spacer block 11 moves upward, it will drive the side ring 5 to move upward. The curved surface 12 is set on the left and right sides of the spacer block 11, and the circumferential surface of the mounting column 3 slides on the curved surface 12 of the spacer block 11, so that the spacer block 11 fits the surface of the mounting column 3 more closely, and supports and stabilizes the mounting column 3.

[0034] Reference Figure 1 、 Figure 4The limiting mechanism includes a plurality of limiting grooves 19 provided on the bottom plate 1, and a limiting plate 15 is slidably connected at both ends of each limiting groove 19. The limiting plates 15 at both ends of each limiting groove 19 are fixedly connected at one end away from each other with a pull ring 14 for facilitating the movement of the limiting plates 15 by the staff. The limiting plates 15 at both ends of each limiting groove 19 are close to each other at one end thereof. A slope 17 is provided. Limiting grooves 18 are provided on the left and right surfaces of the culture rack 2. When the culture rack 2 is installed, the culture rack 2 is pressed downward so that the edge of the culture rack 2 squeezes the slope. Surface 17, so that the limit plate 15 overcomes the elastic force of the reset spring 16 and moves. When the culture rack 2 moves to the bottom, the limit plate 15 will re-enter the interior of the limit groove 18 under the action of the reset spring 16, completing the work of limiting and fixing the mounting rack 2, and playing a one-way limiting effect. The left and right surfaces of the culture rack 2 are provided with limit grooves 18 that match the limit plate 15. The limit plate 15 is elastically connected to the inner wall of the bottom plate 1 through the reset spring 16. By setting the reset spring 16, multiple limit plates 15 have a tendency to approach each other.

[0035] Working principle: During use, when the culture tube 4 needs to be taken out, the staff puts the thumb on the fixing plate 13 and the index finger on the control plate 9, and then applies force upward with the index finger to make the control plate 9 move upward. The displacement of the control plate 9 drives the spacer block 11 to move upward, and the upward displacement of the spacer block 11 drives the side ring 5 and the culture tube 4 to move upward until the culture tube 4 is moved to the upper part of the mounting column 3. Under the friction provided by the fastening ring 7, the culture tube 4 will not fall under the action of gravity, thereby improving stability and facilitating the removal of the culture tube 4. The staff does not need to pull out the culture tubes 4 one by one, which reduces the workload and improves work efficiency.

[0036] By pulling the pull ring 14 outward, the pull ring 14 moves and drives the limit plate 15 to overcome the elastic force of the reset spring 16 and move in the direction away from the center of the base plate 1, so that the limit plate 15 is completely disengaged from the inside of the limit groove 18, thereby releasing the limit on the culture rack 2, and the culture rack 2 can be easily and quickly removed from the base plate 1 for cleaning, ensuring the cleanliness of the culture equipment.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. 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.
