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

[0002] A petri dish is a laboratory dish used for culturing microorganisms or cells. It consists of a flat, disc-shaped bottom and a lid, and is usually made of glass or plastic.

[0003] A Chinese patent document with publication number CN221740310U discloses a detachable cell culture dish, comprising a box body, a dish body and a dish cover, wherein a plurality of placement grooves are evenly opened on the inside of the box body, the dish body is arranged in the placement grooves, and the dish cover is arranged above the dish body. A movable groove is opened on the inside of the box body near the placement grooves, and a movable block is slidably connected in the movable groove. The movable block is located at the bottom of the placement grooves, and a connecting rod is provided on the movable block. The connecting rod passes through the box body and is connected to a pulling block. The end of the pulling block is fixed to the dish cover, and a spring is provided on the outside of the connecting rod above the movable block. The two ends of the spring are respectively connected to the movable block and the movable groove. The movable groove is cylindrical and the movable block is disc-shaped. During the process of culturing cells in the dish body, if problems occur in the cells in some of the dish bodies, the pulling block can be lifted upward, so that the connecting rod drives the movable block to squeeze the spring to contract, and the pulling block drives the dish cover to lift the dish cover, thereby opening the corresponding dish body and taking the dish body out for processing.

[0004] The disadvantage of the above-mentioned disclosed solution is that when placing the dish into the placement groove, it is necessary to pull the pull block upward, which drives the dish cover to move upward and maintain it at a certain height. The pull block can only be released after the dish is placed in and out of the placement groove, which makes it inconvenient for the staff to place the dish. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a cell culture dish that is easy to separate. After the limiting component releases the limit on the connecting disk, the dish cover is separated from the placement box and pops up, which can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a cell culture dish that is easy to separate, comprising a box body, a placement box provided in the box body, a dish cover movably sleeved on the placement box, a sliding groove provided at the bottom of the box body, a connecting disk slidably provided in the sliding groove, a rotating part rotatably provided on the connecting disk, the rotating part extends upward to the top of the sliding groove and is connected to the dish cover, a spring is fixedly provided between the connecting disk and the sliding groove, when the dish cover is closed on the placement box, the spring is in a compressed state, and a limiting component for limiting the connecting disk is provided between the rotating part and the sliding groove.

[0007] Furthermore, the limiting assembly includes a clamping block and a stopper, the stopper is fixedly arranged at the bottom of the sliding groove, the clamping block is fixedly arranged at the bottom of the rotating member, and the clamping block abuts and cooperates with the stopper.

[0008] Furthermore, the limiting assembly includes a threaded block, which is fixedly arranged at the bottom of the rotating member. A threaded hole is provided at the bottom of the sliding groove, and the threaded block is threadedly connected to the threaded hole.

[0009] Furthermore, a plurality of the placement boxes are provided, and the plurality of placement boxes are arranged in a circular array.

[0010] Furthermore, the rotating member is rotatably connected to the dish cover.

[0011] Furthermore, a box cover is slidably provided on the top of the box body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Because a spring is fixedly installed between the connecting disk and the sliding groove, when the dish cover is closed on the placement box, the spring is in a compressed state, and a limiting assembly is provided between the rotating member and the sliding groove to limit the position of the connecting disk. Therefore, when the box cover is opened, the limiting assembly no longer limits the connecting disk. At this time, the restoring force of the spring drives the connecting disk upward, which drives the rotating member upward, and the rotating member drives the dish cover upward, so that the dish cover pops off from above the placement box and is kept at a certain height. This eliminates the need to constantly pull the rotating member upward to keep the dish cover at a certain height, making it easier for workers to place the dish body into the placement box.

[0023] The following will be combined with the accompanying 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.

[0024] For example 1, please refer to Figures 1-6 This embodiment provides a technical solution: a cell culture dish for facilitating separation, comprising a box body 1, with a lid 2 slidably mounted on the top of the box body 1. Multiple placement boxes 6 are disposed at the bottom of the box body 1, arranged in a circular array to facilitate placement of multiple dishes 5 within the box body 1. A dish lid 3 is movably mounted on the top of the placement boxes 6.

[0025] The bottom of the box body 1 is provided with multiple sliding slots 7 arranged in a circular array and extending vertically. A connecting plate 9 slides within the sliding slots 7, upon which a rotating member 4 rotatably rests. The rotating member 4 comprises a rotating rod with a handle fixed to its top. The bottom of the rotating rod is fixedly connected to the center of the connecting plate 9. The rotating rod of the rotating member 4 extends upward above the sliding slots 7 and is rotatably connected to the dish cover 3, facilitating rotation of the dish cover 3 and thereby facilitating the placement of the dish body 5 into the storage box 6.

[0026] A spring 8 is fixedly mounted between the connecting plate 9 and the sliding groove 7. Spring 8 is mounted on the rotating rod of the rotating member 4. When the dish cover 3 is closed on the storage box 6, the spring 8 is compressed. A stopper assembly is provided between the rotating member 4 and the sliding groove 7 to limit the position of the connecting plate 9, thereby preventing the connecting plate 9 from moving upward.

[0027] The limiting assembly includes a clamping block 11 and a stopper 10. Stopper 10 is fixed to the bottom of the wall of the sliding groove 7. The bottom end of the rotating rod of the rotating member 4 passes downward through the connecting plate 9 and extends below the connecting plate 9. The clamping block 11 is fixed to the bottom end of the rotating rod of the rotating member 4 and abuts against the stopper 10 when the clamping block 11 is located below the stopper 10.

[0028] The working principle of a cell culture dish for easy separation provided in this embodiment is as follows:

[0029] During use, cells are cultured in the dish 5, and then the lid 2 is opened. The handle of the rotating member 4 is manually rotated, which drives the block 11 at the bottom end of the rotating rod to rotate. The block 11 disengages from the stopper 10, so that the stopper 10 no longer blocks the block 11, and the block 11 no longer restricts the connection plate 9. At this time, the restoring force of the spring 8 drives the connection plate 9 upward, which drives the rotating rod of the rotating member 4 upward, and the rotating rod drives the dish cover 3 upward, so that the dish cover 3 is completely opened from above the placement box 6 and the dish cover 3 is maintained in a certain position, making it easier to place the dish 5 into the placement box 6.

[0030] In order to prevent the dish cover 3 from being located above the placement box 6 and affecting the placement of the dish body 5, the dish cover 3 can be directly rotated to one side so that the dish cover 3 does not block the top of the placement box 6, further facilitating the placement of the dish body 5 into the placement box 6.

[0031] When closing the dish cover 3 on the placement box 6, the dish cover 3 is positioned above the placement box 6, and the handle of the rotating member 4 is pressed downward to make the clamping block 11 lower than the stopper 10. The handle is then rotated to move the clamping block 11 directly below the stopper 10, so that the stopper 10 blocks the clamping block 11 again, thereby closing the dish cover 3 on the placement box 6. Finally, the box cover 2 is closed and cell culture can be carried out.

[0032] For example 2, please refer to Figure 7-Figure 8 This embodiment provides a technical solution: A technical solution: A cell culture dish that facilitates separation, comprising a box body 1, with a box cover 2 slidably mounted on the top of the box body 1. A plurality of placement boxes 6 are disposed at the bottom of the box body 1. The plurality of placement boxes 6 are arranged in a circular array to facilitate placement of a plurality of dishes 5 within the box body 1. A dish cover 3 is movably mounted on the top of the placement boxes 6.

[0033] The bottom of the box body 1 is provided with multiple sliding slots 7 arranged in a circular array and extending vertically. A connecting plate 9 slides within the sliding slots 7, upon which a rotating member 4 rotatably rests. The rotating member 4 comprises a rotating rod with a handle fixed to its top. The bottom of the rotating rod is fixedly connected to the center of the connecting plate 9. The rotating rod of the rotating member 4 extends upward above the sliding slots 7 and is rotatably connected to the dish cover 3, facilitating rotation of the dish cover 3 and thereby facilitating the placement of the dish body 5 into the storage box 6.

[0034] A spring 8 is fixedly mounted between the connecting plate 9 and the sliding groove 7. Spring 8 is mounted on the rotating rod of the rotating member 4. When the dish cover 3 is closed on the storage box 6, the spring 8 is compressed. A stopper assembly is provided between the rotating member 4 and the sliding groove 7 to limit the position of the connecting plate 9, thereby preventing the connecting plate 9 from moving upward.

[0035] The limiting assembly includes a threaded block 12. The bottom end of the rotating rod of the rotating member 4 passes downward through the connecting plate 9 and extends to the bottom of the connecting plate 9. The threaded block 12 is fixedly mounted on the bottom end of the rotating rod of the rotating member 4. The bottom of the sliding groove 7 is provided with a threaded hole that matches the threaded block 12. The threaded block 12 is threadedly connected to the threaded hole.

[0036] The working principle of a cell culture dish for easy separation provided in this embodiment is as follows:

[0037] During use, cells are cultured in the dish 5, and then the lid 2 is opened. The handle of the rotating member 4 is manually rotated, which drives the threaded block 12 at the bottom end of the rotating rod to rotate. The threaded block 12 rotates out of the threaded hole, thus no longer restraining the connecting plate 9. At this time, the restoring force of the spring 8 drives the connecting plate 9 upward, which in turn drives the rotating rod of the rotating member 4 upward. The rotating rod drives the dish cover 3 upward, causing the dish cover 3 to pop open from above the placement box 6 and maintain the dish cover 3 in a certain position, facilitating the placement of the dish 5 into the placement box 6.

[0038] In order to prevent the dish cover 3 from being located above the placement box 6 and affecting the placement of the dish body 5, the dish cover 3 can be directly rotated to one side so that the dish cover 3 does not block the top of the placement box 6, further facilitating the placement of the dish body 5 into the placement box 6.

[0039] When closing the dish cover 3 on the placement box 6, after the dish cover 3 is positioned above the placement box 6, the handle of the rotating member 4 is pressed downward to allow the threaded block 12 to enter the threaded hole. The handle of the rotating member 4 is then rotated further to drive the threaded block 12 to be threadedly connected to the threaded hole. When the threaded block 12 is fully inserted into the threaded hole, the dish cover 3 is closed on the placement box 6 and fits tightly to the placement box 6. Finally, the box cover 2 is closed and cell culture can be carried out.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
