DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0027] Reference Figure 1-2 , which is the first embodiment of the present utility model, provides an anti-contamination cell culture dish transfer device, including a placement mechanism 200, the placement mechanism 200 includes a culture dish 202, and the culture dish 202 is equipped with a support mechanism 100, an anti-contamination mechanism 300 and a flow control mechanism 400;

[0028] In addition, the upper surface of the culture dish 202 is connected to the ventilation tube 204, and the inner side of the opening of the ventilation tube 204 is clamped and connected to the first isolation layer 301, the second isolation layer 302 and the third isolation layer 303, and the outer side surface of the ventilation tube 204 is fixedly connected to the connecting rope 401, and the connecting rope 401 is adapted to be installed with a disc 402, and the inner side surface of the disc 402 is fixedly connected to the outer cylinder 403, and the surface of the outer cylinder 403 is slidably connected to the inner cylinder 404, and the inner cylinder 404 is cooperated with a limiting component 405.

[0029] Specifically, the supporting mechanism 100, the placement mechanism 200, the anti-fouling mechanism 300 and the flow control mechanism 400 are arranged in coordination, so that the culture dish 202 can control the oxygen input while efficiently filtering and preventing impurities in the gas, further helping the culture dish 202 to be transferred stably. The communication between the vent tube 204 and the culture dish 202 allows the gas to be input and circulated stably. The fixed connection between the disc 402 and the outer cylinder 403 allows the outer cylinder 403 to be stably placed, thereby flexibly adjusting the flow of the vent tube 204, indirectly reducing the intake of microorganisms such as bacteria, and the culture dish 202 can be kept relatively pure. The coordination between the inner cylinder 404 and the limiting member 405 allows the vent tube 204 to adjust the gas output according to the specific application requirements. The coordination of the first isolation layer 301 being glass fiber, the second isolation layer 302 being polyester, and the third isolation layer 303 being PTFE allows the microorganisms in the gas to be intercepted at multiple levels, thereby avoiding affecting the inner cavity of the culture dish 202.

[0030] Furthermore, the limiting member 405 includes a support plate 405-1 fixedly connected to the outside of the inner tube 404, and a hook 405-2 is rotatably connected to one side of the support plate 405-1 through a pin shaft, and the end face of the hook 405-2 is movably engaged with an inverted tooth plate 405-3, and a spring ball 406 is fixedly connected to the lower surface of the inner tube 404, and the bottom of the spring ball 406 is in close contact with the ventilation pipe 204.

[0031] Preferably, the fixed connection between the support plate 405-1 and the inner tube 404 makes the clamping of the hook 405-2 stable and continuous, and the clamping connection between the hook 405-2 and the inverted tooth plate 405-3 can control the lifting and lowering movement of the inner tube 404 to avoid the movement and shaking of the inner tube 404. The fixed connection between the inner tube 404 and the spring ball 406 allows the spring ball 406 to be pushed up and down by the inner tube 404, thereby continuously squeezing the ventilation pipe 204.

[0032] It should be noted that an elastic block 304 is clamped and connected between the second isolation layer 302 and the third isolation layer 303 .

[0033] Afterwards, the elastic block 304 that is clamped between the second isolation layer 302 and the third isolation layer 303 is set, so that the distance between different isolation layers can be adjusted, effectively improving the filtering and anti-fouling effect. Example

[0034] Reference Figure 2-3 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts to achieve firmness, stability and limiting effects.

[0035] Specifically, there are two inverse tooth plates 405 - 3 , which are symmetrically arranged on the sides of the outer cylinder 403 , and the inverse tooth plates 405 - 3 are fixedly mounted on the outer cylinder 403 via an adapter frame.

[0036] Furthermore, the symmetrical arrangement of the two inverted tooth plates 405 - 3 makes the lifting movement of the inner cylinder 404 more symmetrical and balanced, and the gas regulation in the inner cavity of the ventilation tube 204 also tends to be stable, effectively reducing the secondary entry of microorganisms.

[0037] Preferably, a collar 203 is fixedly sleeved on the surface of the culture dish 202 , and an outer frame 201 is plugged and connected to the outer side of the culture dish 202 , and a straight column 103 is fixedly sleeved on the end surface of the outer frame 201 .

[0038] The fixed arrangement of the collar 203 and the culture dish 202 prevents the culture dish 202 from shaking significantly during the experiment, and the fixed connection between the outer frame 201 and the straight column 103 can help to display the culture dish 202 intuitively. Example

[0039] Reference Figure 2-5 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving a continuous limiting effect.

[0040] Specifically, the support mechanism 100 further includes a bearing seat 102 , the inner side surface of the bearing seat 102 is fixedly sleeved with the straight column 103 , and the bottom of the straight column 103 is plugged and connected to the chassis 101 .

[0041] Furthermore, the fixed sleeve arrangement of the bearing seat 102 and the straight column 103 allows the bottom of the straight column 103 to be supported when it rotates, thereby facilitating the rotational display of the culture dish 202.

[0042] Preferably, the maximum rotation angle of the hook 405 - 2 is an acute angle, and the rotation portion of the hook 405 - 2 is coated with grease.

[0043] The acute angle setting of the hook 405 - 2 can make the limiting process safe and stable, thereby making the gas flow control inside the ventilation pipe 204 more stable.

[0044] Working principle: first, the culture dish 202 is fixedly sleeved on the inner side of the outer frame 201, and then the ventilation tube 204 is connected to the culture dish 202 for the gas inside the culture dish 202; then, the connecting rope 401 is fixedly connected to the disc 402, the outer cylinder 403 is fixedly connected to the disc 402, and the side of the inner cylinder 404 is adapted to install the support plate 405-1, and the hook 405-2 is rotated and installed with the support plate 405-1 through the pin shaft, and then the reverse tooth plate 405-3 is fixedly installed to the side of the disc 402, and the hook 405-2 is further limited and locked with the reverse tooth plate 405-3, and then the spring ball 406 is fixedly installed to the inner cylinder 404 for gas volume control. At the same time, the first isolation layer 301, the second isolation layer 302 and the third isolation layer 303 are installed in the inner cavity of the ventilation tube 204 in sequence to block biological contamination by microorganisms.
