Description

Technical Field

[0001] The utility model relates to the technical field of cell culture dishes, and in particular to a cell culture dish which is easy to fix. Background Art

[0002] A cell culture dish generally refers to a common laboratory appliance used for cell culture.

[0003] However, most of the current cell culture dishes are generally placed directly on a table or incubator during use. In this case, once the cell culture dishes are touched by external force, they are prone to displacement or even overturning; or in order to save space inside the incubator, two or more cell culture dishes are stacked on each other. Once the stacked cell culture dishes are touched by external force, they are prone to tipping over; both phenomena can easily cause the material in the cell culture dishes to spill out, affecting the normal operation of cell culture. Utility Model Content

[0004] The utility model provides a cell culture dish which is easy to fix, and solves the problem in the related art that the material inside the cell culture dish is easily spilled due to the contact of external force.

[0005] The technical solution of the utility model is as follows:

[0006] A cell culture dish that is easy to fix includes a dish body, wherein the dish body includes a base and a dish body, the dish body is an annular structure and is fixedly connected to the top of the base, a suction cup is provided below the base, the suction cup is fixedly connected to the base and is made of elastic material, and a connecting groove for adjacent dish bodies to be embedded is provided on the dish body.

[0007] Furthermore, the projection surface of the suction cup on the horizontal plane is an annular structure, and the diameter of the suction cup is greater than or equal to the diameter of the connecting groove.

[0008] Furthermore, the connecting groove is formed in the inner ring of the dish body and penetrates the inner ring of the dish body, and a clamping portion is provided between the base and the suction cup, and the diameter of the clamping portion is less than or equal to the diameter of the connecting groove.

[0009] Furthermore, a buffer portion is provided at one end of the dish body away from the base, the projection surface of the buffer portion on the horizontal plane is an annular structure, and the longitudinal section of the buffer portion is an arc structure.

[0010] Furthermore, a reinforcement body is provided between the base and the dish body, the projection surface of the reinforcement body on the horizontal plane is an annular structure, and the longitudinal section of the reinforcement body is a triangular structure, and the dish body, the base and the reinforcement body are fixedly connected to each other.

[0011] Furthermore, a plurality of auxiliary pressing plates are provided on the base, and the auxiliary pressing plates are symmetrically distributed with the base as the center.

[0012] Furthermore, an anti-accumulation portion is provided at the bottom of the connecting groove, and a diameter of an end of the anti-accumulation portion away from the base is larger than a diameter of an end of the anti-accumulation portion close to the base.

[0013] Furthermore, the height of the connecting groove is lower than the sum of the heights of the clamping portion and the suction cup.

[0014] The working principle and beneficial effects of the utility model are:

[0015] 1. A suction cup is provided under the dish body in the utility model, and the suction cup is made of elastic material. That is, when the staff places the dish body, the suction cup is deformed and the air inside the suction cup is discharged by pressing the dish body downward, and the air pressure difference between the inside and the outside of the suction cup is generated, so that the suction cup generates a certain adsorption force, and the dish body is fixed on the desktop or incubator; because the dish body is fixed, it is not easy to be displaced when it is touched by external force, so that the culture work of the cells contained in the dish body is more stable.

[0016] 2. The dish body in the utility model is provided with a connecting groove. The existence of the connecting groove enables adjacent dish bodies to fit together. Due to the fitting relationship between the two, a certain restraining effect can be exerted on the two, thereby preventing the dish body located above from being displaced when subjected to force, causing it to slide off the adjacent dish body or even cause the entire dish to tip over, thereby ensuring the stability of the utility model after being stacked on each other.

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 to Figure 4 As shown, the present embodiment provides a cell culture dish that is easy to fix, mainly comprising a dish body 1, wherein the dish body 1 comprises a base 11 and a dish body 12, wherein the dish body 12 is an annular structure and is fixedly connected to the top of the base 11, and a suction cup 2 is provided below the base 11, wherein the suction cup 2 is fixedly connected to the base 11 and is made of an elastic material, that is, when a worker places the dish body 1, he only needs to press the dish body 1 to squeeze the suction cup 2 at the bottom of the base 11 to deform the suction cup 2, thereby discharging the air inside the suction cup 2, generating an air pressure difference between the inside and outside of the suction cup 2, and generating a certain adsorption of the suction cup 2, thereby fixing the dish body 1 on a relatively smooth contact surface such as a desktop or the inside of an incubator, so as to prevent the dish body 1 from being displaced when being touched by an external force, thereby causing the cells inside the dish body 1 to be in an unstable state.

[0029] The dish body 12 is provided with a connecting groove 121 for the adjacent dish body 1 to be embedded, that is, the dish body 12 is used as a supporting part to ensure the supporting effect on the adjacent dish body 1. At the same time, since the dish body 12 is provided with a connecting groove 121, the stacking connection of the adjacent dish bodies 1 is connected in a mutually embedded manner, that is, the suction cup 2 of the dish body 1 located at the upper is embedded in the connecting groove 121 of the dish body 1 located at the lower, so that there is a mutually constrained relationship between the adjacent dish bodies 1, thereby preventing the upper dish body 1 from being displaced when subjected to force, sliding off the adjacent dish body 1, or even causing the entire dish body 1 to tip over, thereby ensuring the stability of multiple dish bodies 1 when stacked on each other.

[0030] At the same time, the elastic material constituting the suction cup 2 should preferably be an elastic material with good chemical corrosion resistance such as silicone to prevent the suction cup from being corroded by chemical reactions generated during the cell culture process and ensure the service life of the suction cup.

[0031] The projection surface of the suction cup 2 on the horizontal plane is an annular structure, which facilitates the suction cup 2 to be embedded in the connecting groove 121, and the diameter of the suction cup 2 is greater than or equal to the diameter of the connecting groove 121, that is, the suction cup 2 will be deformed to a certain extent during the process of being embedded in the connecting groove 121, thereby squeezing the inner wall of the connecting groove 121, so that the suction cup 2 embedded in the connecting groove 121 is difficult to be separated from the connecting groove 121 without the intervention of a very large external force (active disassembly by manpower), thereby improving the connection strength when adjacent dish bodies 1 are connected to each other.

[0032] The connecting groove 121 is formed on the inner ring of the dish body 12 and penetrates the inner ring of the dish body 12, so as to avoid having groove walls on both sides of the connecting groove 121, which makes it difficult for the suction cup 2 to be inserted into the connecting groove 121. In addition, the connecting groove 121 is formed on the side of the dish body 12 close to the center of the base 11, so that the dish body 12 itself can protect the suction cup 2 between the adjacent dish body 12 and the suction cup 2, thereby improving the stability when the two are connected.

[0033] Furthermore, since the suction cup 2 is made of elastic material, the suction cup 2 embedded in the connecting groove 121 may still be deformed under the action of a horizontal force, thereby causing the dish body 1 to shake. Therefore, a clamping portion 111 is provided between the base 11 and the suction cup 2. The clamping portion 111 and the base 11 are integrally formed, so that when the staff connects the two dish bodies 1, they are embedded into the connecting groove 121 together with the clamping portion 111. The mutual constraint between the clamping portion 111 and the connecting groove 121 prevents the dish body 1 from shaking under force. The diameter of the clamping portion 111 is less than or equal to the diameter of the connecting groove 121, so that the clamping portion 111 is conveniently embedded in the connecting groove 121.

[0034] A buffer portion 122 is provided at one end of the dish body 12 away from the base 11. The projection surface of the buffer portion 122 on the horizontal plane is an annular structure, and the longitudinal section of the buffer portion 122 is an arc structure, that is, the arc structure is used to evenly disperse the force when the staff presses the dish body 1, so that the dish body 1 as a whole has a higher structural strength and is not easy to deform.

[0035] At the same time, since there may be cells already inside the dish body 1 when the dish body 1 is installed, in order to prevent the microorganisms on the hands of the staff from entering the dish body 1 when the staff presses the dish body 1 and confusing the experimental results, a plurality of auxiliary pressing plates 4 are provided on the base 11. The dish body 1 is fixed by pressing the auxiliary pressing plates 4. The auxiliary pressing plates 4 are symmetrically distributed with the base 11 as the center, which makes it convenient for the staff to press the auxiliary pressing plates 4, and the force during pressing can be relatively balanced.

[0036] A reinforcing body 3 is provided between the base 11 and the dish body 12. The longitudinal section of the reinforcing body 3 is a triangular structure. The dish body 12, the base 11, and the reinforcing body 3 are fixedly connected to each other, that is, by virtue of the firm and reliable characteristics of the triangular structure, the dish body 12 is prevented from being deformed when subjected to pressure, thereby improving the bearing capacity of the dish body 12; and the projection surface of the reinforcing body 3 on the horizontal plane is an annular structure, so as to avoid an angle between the reinforcing body 3 and the dish body 12 or the base 11, because such an angle may eventually constitute a sanitary dead angle, resulting in the accumulation of dirt, bacteria or other harmful substances inside the dish body 1, which is very likely to affect the later cell culture work and the service life of the dish body 1.

[0037] The height of the connecting groove 121 is lower than the sum of the heights of the clamping portion 111 and the suction cup 2, so that after the adjacent dish bodies 1 are stacked, there is a gap between the two, which facilitates the subsequent disassembly of the adjacent dish bodies 1.

[0038] Example 2

[0039] like Figure 5-6 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that an anti-accumulation portion 1211 is provided at the bottom of the connecting groove 121, and the diameter of the end of the anti-accumulation portion 1211 away from the base 11 is larger than the diameter of the end of the anti-accumulation portion 1211 close to the base 11, that is, the anti-accumulation portion 1211 makes the bottom of the connecting groove 121 present an inclined structure, thereby preventing the liquid from being retained at the bottom of the connecting groove 121 or being stuck in the angle between the connecting groove 121 and the dish body 12 when the staff injects the culture liquid or the like into the dish body 1, resulting in an imbalance in the ratio of cells to the culture liquid or the like inside the dish body 1, thereby affecting the normal use of this embodiment.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
