Description

Technical Field

[0001] This utility model relates to the technical field of culture dish placers, and in particular to a batch cell culture dish placer. Background Technology

[0002] A cell culture dish is a laboratory vessel used for cell culture. It consists of a flat, disc-shaped lid and the dish body, and is usually made of glass or plastic. Generally, the diameter of the lid is larger than that of the dish body, and both the lid and the dish body have smooth surfaces. The lid is placed on top of the dish body, and both the lid and the dish body must be held simultaneously during use. To control experimental conditions such as culture temperature, the microorganisms or cells inoculated into the culture dish need to be placed in an incubator for cultivation. Usually, to prevent condensation from the lid from dripping and causing contamination, the culture dish needs to be placed upside down and flat in the incubator.

[0003] Traditional stacking of petri dishes can cause them to slip and require moving the upper dishes to retrieve them, which can easily lead to contamination or breakage. External force can also cause the petri dishes to shift or spill their contents. Furthermore, experiments with multiple petri dishes can easily lead to sample confusion, and long-term storage can result in moisture contamination. Traditional stacking also hinders gas exchange. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a layered structure cell culture dish holder that can limit the cell culture dish and prevent it from falling.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes a suction cup base and a placement seat assembly disposed above the suction cup base. The placement seat assembly includes several placement racks, a limiting baffle corresponding to and cooperating with the guide of the corresponding placement rack, and a tray disposed in the middle of the corresponding placement rack. Each placement rack is connected sequentially from bottom to top, and each placement rack forms a placement space for placing a petri dish. The inner wall of each placement space is formed with a guide strip that cooperates with the guide of the limiting baffle. The lower surface of the placement space is provided with several positioning posts for guiding and connecting the placement racks.

[0006] Furthermore, the outer wall of the limiting baffle is formed with a guide groove that cooperates with the guide strip, a limiting pad that is pressed and fitted with the guide strip is formed in the guide groove, and a pressure strip that cooperates with the tray is formed at the bottom of the inner wall of the limiting baffle.

[0007] Furthermore, the upper surface of the placement rack is formed with a plurality of positioning sleeves, and the lower surface of the placement rack is formed with connecting posts corresponding to and guided by the respective positioning sleeves.

[0008] Furthermore, the placement seat assembly also includes a cover plate, the lower surface of which is formed with a plurality of protrusions, each of which corresponds to and is guided by a corresponding positioning sleeve.

[0009] Furthermore, the center of the tray has several openings for ventilation, the edge of the tray has several positioning holes corresponding to the positioning pins, and the front of the tray has a clearance opening.

[0010] Furthermore, the upper part of the suction cup base has several reserved holes, each of which corresponds to a guide engagement with a corresponding connecting post. The bottom of the suction cup base has a suction cup fixing sleeve, and each suction cup fixing sleeve is provided with a supporting suction cup.

[0011] Furthermore, both ends of the placement rack have protruding plates, and the placement rack assembly is provided with two handles. Each handle is fixedly connected to the protruding plate on the corresponding side, and the upper end of each handle has a grip for easy holding.

[0012] The beneficial effects of this utility model are as follows: Because this utility model uses a placement rack connected sequentially from bottom to top, with each pair of placement racks connected and fixed by a positioning sleeve and connecting column structure, and a reserved space for gas flow between adjacent placement racks, it enables independent layering and placement of culture dishes. A limiting baffle can be pulled out after a culture dish is placed in the placement rack to restrict the displacement of the culture dish, effectively preventing it from slipping off. Single-dish placement and removal operations can be achieved without interfering with other culture dishes, improving experimental efficiency. The bottom of the suction cup base is equipped with multiple supporting suction cups, which are negative pressure suction cups that are fixed to the table surface by negative pressure adsorption, enhancing operational stability and reducing the risk of accidental spillage. The center of the tray has multiple openings for ventilation, which helps maintain a constant humidity environment in conjunction with the external placement environment, extending the storage period of the culture dishes and ensuring sample viability.

[0021] like Figures 1 to 4 As shown, in this embodiment, the present invention includes a suction cup base 1 and a placement seat assembly 2 disposed above the suction cup base 1. The placement seat assembly 2 includes a plurality of placement racks 21, a limiting baffle 22 corresponding to and cooperating with the corresponding placement rack 21, and a tray 23 disposed in the middle of the corresponding placement rack 21. Each placement rack 21 is connected sequentially from bottom to top. Each placement rack 21 forms a placement space 24 for placing a petri dish. The inner wall of each placement space 24 is formed with a guide strip 25 that cooperates with the limiting baffle 22. The lower surface of the placement space 24 is provided with a plurality of positioning posts 29 for guiding and connecting the placement racks 21.

[0022] The system employs a series of placement racks 21 connected from bottom to top. Each pair of placement racks 21 is connected and fixed via a positioning sleeve 26 and a connecting post 27. Space is reserved between adjacent placement racks 21 for gas flow, enabling independent placement and removal of culture dishes in layers. A limiting baffle 22 can be pulled out after a culture dish is placed in the placement rack 21 to restrict the displacement of the culture dish and effectively prevent it from slipping off. This allows for single-dish placement and removal without interfering with other culture dishes, improving experimental efficiency. The bottom of the suction cup base 1 is equipped with multiple supporting suction cups 13, which are negative pressure suction cups. They are fixed to the table surface by negative pressure adsorption, enhancing operational stability and reducing the risk of accidental spillage. The tray 23 has multiple openings 231 in the middle for ventilation, which helps maintain a constant humidity environment in conjunction with the external placement environment, extending the storage period of the culture dishes and ensuring sample viability.

[0023] like Figure 5As shown, in this embodiment, the outer wall of the limiting baffle 22 has a guide groove 221 that cooperates with the guide strip 25. A limiting pad 222 that presses against the guide strip 25 is formed inside the guide groove 221. A pressure strip 223 that cooperates with the tray 23 is formed at the bottom of the inner wall of the limiting baffle 22. A limiting block is also formed on the outer wall of the limiting baffle 22, and a protrusion that abuts against the limiting block and cooperates with it is formed on the inner wall of the placement rack 21. The protrusion limits the maximum displacement of the limiting baffle 22 and prevents it from slipping.

[0024] Specifically, the limiting pad 222 is fixedly connected to the inner wall of the guide groove 221. The limiting pad 222 is made of rubber to provide friction. The friction generated prevents the limiting baffle 22 from moving back and forth under non-human conditions, thereby improving the safety of the petri dish during storage.

[0025] like Figure 4 As shown, in this embodiment, a plurality of positioning sleeves 26 are formed on the upper surface of the placement frame 21, and a connecting post 27 is formed on the lower surface of the placement frame 21, which is guided and connected to the corresponding positioning sleeve 26. The positioning sleeves 26 and the connecting post 27 work together to simplify the installation process, making alignment simple and convenient, and improving the ease of use for staff.

[0026] In this embodiment, the placement seat assembly 2 further includes a cover plate 3, the lower surface of which is formed with a plurality of protrusions 31, each of which corresponds to a positioning sleeve 26 for guiding engagement.

[0027] like Figure 6 As shown, in this embodiment, the tray 23 has a plurality of openings 231 for ventilation in the middle, and the edge of the tray 23 has a plurality of positioning holes 232 corresponding to and engaging with the corresponding positioning posts 29. The front side of the tray 23 has a clearance opening 233. The clearance opening 233 facilitates the placement of the culture dish by staff, while the openings 231 help maintain a constant humidity environment in conjunction with the external placement environment, extending the storage period of the culture dish and ensuring sample viability.

[0028] like Figure 6 As shown, in this embodiment, the upper part of the suction cup base 1 has a plurality of reserved holes 11, each of the reserved holes 11 corresponding to the corresponding connecting post 27 for guiding engagement. The bottom of the suction cup base 1 has a suction cup fixing sleeve 12, and each suction cup fixing sleeve 12 is provided with a supporting suction cup 13. The supporting suction cup 13 is a negative pressure suction cup, and the upper part of the supporting suction cup 13 is provided with an insertion rod, which is guided and connected to the suction cup positioning sleeve 26.

[0029] like Figure 1 and Figure 2As shown, in this embodiment, both ends of the placement rack 21 have protruding plates 28. The placement rack 21 is provided with two handles 4, each handle 4 being fixedly connected to the corresponding protruding plate 28 on one side. The upper end of each handle 4 has a handle 41 for easy gripping. The handles 4 are fixedly connected to multiple protruding plates 28 by screws. The overall structure is simple, the connection is efficient, and the efficiency of daily petri dish storage is improved.

[0030] The working principle of this utility model:

[0031] Place the petri dish on the corresponding tray 23, and the staff moves the limiting baffle 22 to a suitable position to limit the petri dish in the placement space 24.

[0032] When it is necessary to transfer the culture dish, the staff holds handle 4 and transfers the cells to the appropriate location.

[0033] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
