Description

Technical Field

[0001] This utility model belongs to the field of cell culture technology, and in particular relates to a cell culture plate. Background Technology

[0002] A cell culture plate is a laboratory instrument used for culturing and observing cells in a laboratory. It is typically made of plastic or glass and is designed as a groove or plate with multiple wells to provide the surface and environment necessary for cell growth. Each well can hold a small number of cells, making it suitable for different types of cell culture and experiments.

[0003] However, some culture researchers do not need to use all cells on the same culture plate when culturing cells, and cell culture plates are generally for single use, which can easily lead to unnecessary waste of resources and increase input costs. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cell culture plate, comprising:

[0005] The base plate is a square plate.

[0006] A culture cell, having several of them, wherein the culture cell is cylindrical;

[0007] The stud is fixedly installed at the lower end of the culture cell;

[0008] A screw hole is formed through the base plate, and the position of the screw hole corresponds to the stud.

[0009] Positioning components, used to position the culture cell;

[0010] Each of the aforementioned culture cells is threadedly connected to the base plate.

[0011] Furthermore, the positioning component includes:

[0012] A positioning ring, which is fixedly mounted on the base plate, is a hollow ring.

[0013] The number of positioning rings matches the number of screw holes, with several screw holes distributed within several positioning rings. The positioning rings are coaxial with the screw holes inside them, and the studs are coaxial with the culture grid. After the culture grid is threadedly connected to the base plate, the lower end of the outer ring of the culture grid is located within the positioning rings.

[0014] Furthermore, the inner ring of the positioning ring is interference-fitted with the outer ring of the culture cell.

[0015] Furthermore, it also includes:

[0016] The support legs are fixedly installed at the bottom of the base plate.

[0017] Further, it further includes:

[0018] A slotted cross recess, which is formed at the lower end of the stud.

[0019] Further, when the culture grid is threadedly connected to the bottom plate, the section of the stud with the slotted cross recess is located between the lower surface of the bottom plate and the lower surface of the support leg.

[0020] Further, it further includes:

[0021] A rectangular strip, which is in a figure-eight shape, and the rectangular strip is fixedly arranged on the bottom plate;

[0022] A cover body, the inner circle of which is matched with the outer circle of the rectangular strip;

[0023] Wherein, the inner circle of the rectangular strip and the upper surface of the bottom plate form a cavity, the culture grid is located in the cavity, and the cover body is covered on the cavity.

[0024] Further, it further includes:

[0025] A chamfer, which is formed on the outer circle of the rectangular strip;

[0026] Wherein, the inner contour of the cover body has an inclined surface matched with the chamfer.

[0027] Further, it further includes:

[0028] A condensation ring, and a plurality of condensation rings are arranged in the cover body;

[0029] Wherein, the condensation ring is a hollow ring, and the positions of the plurality of condensation rings correspond to the positions of the plurality of culture grids respectively.

[0030] Further, the upper surface of the culture grid protrudes from the upper surface of the rectangular strip.

[0031] The beneficial effects of the present utility model are as follows:

[0032] 1. By providing a detachable culture grid, the bottom plate can be reused by replacing the culture grid. At the same time, when only a part of the culture grids are needed, the required culture grids can be threadedly connected to the bottom plate, avoiding waste of resources. After use, the used culture grids can be disassembled and discarded, and new culture grids can be replaced to save costs.

[0033] 2. By setting a positioning ring, after the culture cell is threadedly connected to the base plate, the lower end of the outer ring of the culture cell will be located inside the positioning ring. The position of the culture cell is positioned by the cooperation between the outer ring of the culture cell and the inner ring of the positioning ring. This ensures that the position of the culture cell is vertical and stable relative to the base plate after installation, and also prevents the culture cell from shaking, which would affect the culture effect and facilitate the installation and use of the culture cell.

[0034] 3. Because the inner ring of the positioning ring is interference-fitted with the outer ring of the culture cell, when the culture cell is connected to the base plate, it can move downward through the force generated by the threaded fit, so that the lower end of the culture cell enters the inner ring of the positioning ring. This causes the inner ring of the positioning ring to generate a large frictional force between itself and the lower end of the outer ring of the culture cell through the interference fit, which makes the installation of the culture cell stable and prevents the culture cell from rotating, thus avoiding the culture cell from becoming loose from the base plate.

[0035] 4. By setting up support legs, the base plate is raised, making the base plate more stable and less prone to shaking.

[0036] 5. Since it is difficult to remove the culture cell when the positioning ring and the culture cell are in an interference fit, a slot is provided. The slot can be turned with a flathead screwdriver to rotate the stud and remove the culture cell. This makes it easier to remove the culture cell when it is in an interference fit and makes it easier to rotate the stud.

[0037] 6. Since the slotted section is formed by cutting away material, the section of the stud with the slotted section may have a force that deforms towards the slotted section. When this section is located inside the screw hole, it may affect the threaded connection effect. However, by setting it so that after the culture grid is installed, the section of the stud with the slotted section is located between the lower surface of the base plate and the lower surface of the support leg, the solid stud is located inside the screw hole, resulting in a better fixing effect.

[0038] 7. By setting rectangular strips and a cover, it is easy to cover the culture cell, preventing dust and foreign objects from entering. At the same time, the rectangular strips also have a positioning effect for covering the cover.

[0039] 8. By setting chamfers and bevels, when the cover plate is closed, the bevel of the cover plate is placed towards the chamfer of the rectangular strip, so that the closing position of the cover plate is uniform.

[0040] 9. By incorporating a condensation ring, the evaporation and condensation of the solution can be effectively reduced.

[0041] 10. The upper edge of the culture tray is slightly higher than the upper surface of the rectangular strip, which effectively prevents cross-contamination. Attached Figure Description

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings indicate similar items, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0050] Example 1:

[0051] This embodiment provides a cell culture plate, comprising:

[0052] Base plate 1 is a square plate;

[0053] A culture cell 2, having several of them, wherein the culture cell 2 is cylindrical;

[0054] Stud 3 is fixedly installed at the lower end of culture cell 2;

[0055] A screw hole 4 is formed through the base plate 1, and the position of the screw hole 4 corresponds to the screw stud 3;

[0056] A positioning component for positioning culture trough 2;

[0057] The plurality of culture cells 2 are all threadedly connected to the base plate 1.

[0058] In this technical solution, the culture tray 2 is a cylindrical shape used for cell culture. The culture tray 2 is detachably connected to the base plate 1 by a stud 3, so that when only a portion of the culture tray 2 is needed, the required culture tray 2 can be threadedly connected to the base plate 1, avoiding resource waste. At the same time, after use, the used culture tray 2 can be disassembled and discarded, replaced with a new culture tray 2, and the base plate 1 can be disinfected and cleaned for reuse. Both the culture tray 2 and the base plate 1 are made of plastic.

[0059] Additionally, this invention may include a plug 13, which is threadedly connected to the screw hole 4. When only a portion of the culture cell 2 needs to be used, the plug 13 is screwed into the empty screw hole 4 to seal the empty screw hole 4, thereby preventing foreign objects or bacteria and insects from entering and affecting cell culture.

[0060] The outer edge of the base plate 1 may have anti-slip texture (not shown in the figure) for picking up.

[0061] Through this structural design, the detachable culture cell 2 is provided, which allows the base plate 1 to be reused by replacing the culture cell 2. When only a portion of the culture cell 2 is needed, the required culture cell 2 can be threaded to the base plate 1 to avoid resource waste. After use, the used culture cell 2 can be disassembled and discarded, and a new culture cell 2 can be replaced to save costs.

[0062] Example 2:

[0063] This embodiment provides a cell culture plate, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0064] Furthermore, the positioning component includes:

[0065] Positioning ring 5 is fixedly mounted on base plate 1, and positioning ring 5 is a hollow ring;

[0066] The number of positioning rings 5 ​​matches the number of screw holes 4. Several screw holes 4 are distributed in several positioning rings 5. The positioning rings 5 ​​are coaxial with the screw holes 4 inside them. The studs 3 are coaxial with the culture grid 2. After the culture grid 2 is threadedly connected to the base plate 1, the lower end of the outer ring of the culture grid 2 is located inside the positioning rings 5.

[0067] With this structural design, a positioning ring 5 is set up. After the culture grid 2 is threadedly connected to the base plate 1, the lower end of the outer ring of the culture grid 2 will be located inside the positioning ring 5. The position of the culture grid 2 is positioned by the cooperation between the outer ring of the culture grid 2 and the inner ring of the positioning ring 5. This ensures that after the culture grid 2 is installed, its position is vertical and stable relative to the base plate 1, and the culture grid 2 will not shake, which would affect the culture effect. This makes the installation and use of the culture grid 2 convenient.

[0068] Example 3:

[0069] This embodiment provides a cell culture plate, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0070] Furthermore, the inner ring of the positioning ring 5 is interference-fitted with the outer ring of the culture cell 2.

[0071] Through this structural design, since the inner ring of the positioning ring 5 is interference-fitted with the outer ring of the culture cell 2, when the culture cell 2 is connected to the base plate 1, it can move downward through the force generated by the threaded fit, so that the lower end of the culture cell 2 enters the inner ring of the positioning ring 5. This causes the inner ring of the positioning ring 5 to generate a large frictional force between itself and the lower end of the outer ring of the culture cell 2 through the interference fit, which makes the installation of the culture cell 2 stable and prevents the culture cell 2 from rotating, thus avoiding the culture cell 2 from becoming loose from the base plate 1.

[0072] Example 4:

[0073] This embodiment provides a cell culture plate, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0074] Furthermore, it also includes:

[0075] Support leg 6 is fixedly installed at the lower end of base plate 1.

[0076] Through this structural design, the support legs 6 are set up to elevate the base plate 1, making the base plate 1 more stable and less prone to shaking.

[0077] Example 5:

[0078] This embodiment provides a cell culture plate, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0079] Furthermore, it also includes:

[0080] A slotted groove 7 is formed at the lower end of the stud 3.

[0081] With this structural design, when the positioning ring 5 and the culture grid 2 are in interference fit, it is rather laborious to remove the culture grid 2. By providing the slotted groove 7, a slotted screwdriver can be used to turn the slotted groove 7, so as to drive the stud 3 to rotate, thereby removing the culture grid 2, facilitating the removal of the culture grid 2 during interference fit, and making it more labor-saving to drive the stud 3 to rotate.

[0082] Embodiment 6:

[0083] This embodiment provides a cell culture plate, which, in addition to including the technical solutions of the above embodiments, further has the following technical features.

[0084] Furthermore, when the culture grid 2 is threadedly connected to the bottom plate 1, the section of the stud 3 with the slotted groove 7 is located between the lower surface of the bottom plate 1 and the lower surface of the support leg 6.

[0085] With this structural design, the stud 3 will not protrude from the support leg 6, resulting in unstable overall placement. At the same time, since the slotted groove 7 is formed by cutting materials, a force tending to deform towards the inside of the slotted groove 7 may exist on the section of the stud 3 with the slotted groove 7. When this section is located in the screw hole 4, it may affect the thread connection effect. However, by setting that after the culture grid 2 is installed, the section of the stud 3 with the slotted groove 7 is located between the lower surface of the bottom plate 1 and the lower surface of the support leg 6, it means that the solid stud 3 is located in the screw hole 4, making the fixing effect better.

[0086] Embodiment 7:

[0087] This embodiment provides a cell culture plate, which, in addition to including the technical solutions of the above embodiments, further has the following technical features.

[0088] Furthermore, it further includes:

[0090] A cover body 9, the inner circle of which matches the outer circle of the rectangular strip 8;

[0091] Among them, the inner circle of the rectangular strip 8 and the upper surface of the bottom plate 1 form a cavity, the culture grid 2 is located in the cavity, and the cover body 9 is covered on the cavity.

[0092] Furthermore, at the same time, the upper surface of the rectangular strip 8 has obvious markings 14, whose positions correspond to those of the culture grids 2 and are used for easy positioning during experiments.

[0093] Through this structural design, the rectangular strip 8 and the cover 9 are set to facilitate the covering of the culture cell 2, preventing dust and foreign objects from entering. At the same time, the rectangular strip 8 plays a positioning role in covering the cover 9.

[0096] Furthermore, it also includes:

[0097] A chamfer of 10 is formed on the outer ring of rectangular strip 8;

[0098] The inner contour of the cover 9 has a bevel 11 that matches the chamfer 10.

[0099] With this structural design, by setting the chamfer 10 and the bevel 11, when the cover plate is closed, the bevel 11 of the cover plate is placed towards the chamfer 10 of the rectangular strip 8, so that the closing position of the cover plate is uniform.

[0100] Example 9:

[0101] This embodiment provides a cell culture plate, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0102] Furthermore, it also includes:

[0103] Agglomeration ring 12, a plurality of agglomeration rings 12 are provided inside the cover body 9;
