Description
Technical Field
[0001] The utility model relates to the technical field of culture dishes, in particular to a multi-layer cell culture dish for biological laboratories. Background Art
[0002] A culture dish is a common laboratory utensil, mainly used for the culture of microorganisms or cells. It is usually made of glass or plastic. The glass one can be used for plant materials, microbial culture and adherent culture of animal cells. The plastic one is mainly made of polyethylene. There are disposable and multiple-use ones, which are suitable for laboratory inoculation, streaking, and separation of bacteria. They are mainly used for the culture of plant materials.
[0003] Currently, most common cell culture dishes are similar in structure, consisting of a flat disc-shaped bottom and a lid. In actual use, there are some functional deficiencies and room for improvement. For example, culture dishes are mostly used alone, and when multiple culture dishes are stacked for multi-layer sample comparison, the culture dishes are prone to sliding and falling. Some styles of culture dishes have grooves on the top of the lid and clamps on the bottom of the dish. However, after the clamps are stacked, when taking the upper dish, there is a certain probability that the lid of the lower dish will be lifted, which is not convenient to use. Utility Model Content
[0004] In view of the above-mentioned defects of the prior art, the task of the utility model is to provide a multi-layer cell culture dish for biological laboratories, so as to facilitate the multi-layer stacking of culture dishes and solve the problem that the top cover of the lower culture dish is easily lifted when taking the upper culture dish, thereby improving stability.
[0005] The technical scheme of the utility model is as follows: A multi-layer cell culture dish for biological laboratories, comprising a plurality of single-layer components, wherein the single-layer components comprise a dish bottom and a sealed top cover which can be covered with each other, a plurality of externally extending bolt rods are arranged on the peripheral side of the sealed top cover, one end of the externally extending bolt rods is fixedly connected with a bolt rod head, a limiting component is arranged on the periphery of the dish bottom, the limiting component comprises at least two first fixing seats and at least two second fixing seats, a vertical positioning pin rod is arranged on the first fixing seat, the top of the positioning pin rod is higher than the top surface of the sealed top cover, the second fixing seat is provided with a positioning pin hole, and when a plurality of the single-layer components are stacked, the positioning pin rod of the single-layer component of the lower layer is inserted into the positioning pin hole of the single-layer component of the upper layer.
[0006] Furthermore, the positioning pin rod and the positioning pin hole are clearance-matched. The clearance-matched positioning pin rod and the positioning pin hole have an appropriate relative movement gap, which can facilitate taking and placing and reduce jamming.
[0007] Furthermore, the top of the positioning pin rod is a tapered cone. When multiple single-layer components are stacked, the positioning pin rod with a tapered cone at the top is easier to align with the positioning pin hole, thereby improving the convenience of stacking.
[0008] Furthermore, two of the first fixing seat and the second fixing seat are respectively provided, and the first fixing seat and the second fixing seat are arranged at an interval of 90° from each other in the circumferential direction of the outer periphery of the bottom of the plate.
[0009] Furthermore, the top surface of the sealing cover is provided with a plurality of convex points, and the arrangement of the convex points can prevent the bottom surface of the tray bottom from being attracted to the top surface of the sealing cover after stacking.
[0010] Furthermore, a sealing rubber ring is provided on the top surface of the inner cavity of the sealing top cover.
[0011] Furthermore, the sealing top cover is magnetically attracted to the top edge of the plate bottom through the sealing rubber ring.
[0012] The advantages of the utility model compared with the prior art are:
[0013] By plugging the limiting components on the multiple single-layer components into each other, the stacked multiple single-layer components can be positioned relative to each other without sliding, thus having good stability and facilitating experimental operation.
[0014] After the convex points are arranged on the sealing top cover, when the upper culture dish is removed, the sealing top cover at the lower layer will not be lifted up synchronously.
[0015] On the one hand, the externally extended bolt rod can facilitate the hanging of labels to mark the samples in the culture dish, and it is easy to replace the labels to change the information. On the other hand, it is also convenient to control the sealed top cover of the lower single-layer component from being lifted up when the upper single-layer component is removed after stacking.

[0020] The present invention will be further described below in conjunction with the embodiments, but is not intended to limit the present invention.
[0021] Please combine Figures 1 to 4 As shown, the present embodiment involves a multi-layer cell culture dish for use in biological laboratories, comprising three single-layer components, each of which comprises a dish bottom 1 and a sealing top cover 3. A circle of top cover positioning ring 2 is provided on the periphery of the dish bottom 1. The sealing top cover 3 can be covered on the dish bottom 1 and docked with the top cover positioning ring 2, and a culture space is formed between the dish bottom 1 and the sealing top cover 3.
[0022] The bottom of the dish 1 is roughly circular, and a position limiting assembly is provided on the periphery of the bottom of the dish 1 for easy stacking. In this embodiment, the position limiting assembly includes two first fixing seats 4 and two second fixing seats 6. The two first fixing seats 4 are fixedly connected to the left and right sides of the bottom of the dish 1, respectively, and the second fixing seats 6 are located on the front and back sides of the bottom of the dish 1. In this way, the first fixing seats 4 and the second fixing seats 6 are arranged at a 90° interval from each other in the circumferential direction of the outer periphery of the bottom of the dish, and when multiple single-layer assemblies are stacked, the first fixing seats 4 and the second fixing seats 6 can correspond to each other. The shapes and sizes of the first fixing seats 4 and the second fixing seats 6 can be set to be consistent.
[0023] The relative sliding of multiple single-layer components is limited by the corresponding first fixed seat 4 and the second fixed seat 6. Specifically, a vertical positioning pin rod 5 is fixedly connected to the top of the first fixed seat 4, and a positioning pin hole 7 is arranged inside the second fixed seat 6. The top of the positioning pin rod 5 is higher than the top surface of the sealing top cover 3. The outer diameter of the positioning pin rod 5 and the inner diameter of the positioning pin hole 7 are matched, and the two form a clearance fit. The positioning pin rod 5 can move up and down along the inside of the positioning pin hole 7, which is convenient for stacking to form multiple layers. In order to make it easier for the positioning pin rod 5 to align with the positioning pin hole 7, the top of the positioning pin rod 5 is a tapered cone.
[0024] The positioning pin rod 5 on the first fixing seat 4 of the lower culture dish is inserted into the positioning pin hole 7 inside the second fixing seat 6 of the upper culture dish, and the upper and lower layers are nested to prevent sliding displacement between the culture dishes. In addition, a plurality of protrusions 16 are provided on the top surface of the sealing top cover 3, so that the bottom surface of the upper dish bottom 1 will not be completely in contact with the top surface of the lower sealing top cover 3 after the upper and lower dishes are stacked, and the lower sealing top cover 3 will not be lifted up when the upper culture dish is removed.
[0025] Please further combine Figure 3 , Figure 4 As shown, in some embodiments, a magnetic ring 8 is buried inside the top ring of the dish bottom 1, a sealing rubber ring 9 is clamped on the top surface of the inner cavity of the sealing top cover 3, and a ferromagnetic ring 10 is arranged inside the sealing rubber ring 9. The inner diameter of the sealing rubber ring 9 is consistent with the inner diameter of the top ring of the dish bottom 1, which can increase the sealing performance of the culture dish. The sealing rubber ring 9 inside the sealing top cover 3 is pressed on the top ring position of the dish bottom 1, and the magnetic ring 10 and the stainless steel ring 8 are attracted to each other, so that the sealing rubber ring 9 can be closely attached to the top ring of the dish bottom 1, thereby increasing the sealing performance and reducing the risk of leakage.
[0026] Two sets of externally extending bolt rods 11 are fixedly connected to the front and rear ends of the sealing top cover 3, and one end of the externally extending bolt rod 11 is fixedly connected to a bolt rod head 12 which is slightly thicker than the externally extending bolt rod 11. The externally extending bolt rod 11 can be conveniently hung with a label to mark the sample and also conveniently control the sealing top cover 3. Figure 4 As shown, the corresponding information of the sample is filled in on the label plate 13, and the label plate 13 is connected with an elastic rope 14. A rubber elastic ring 15 is set at the end of the elastic rope 14 to expand and sleeve on the external extension bolt rod 11. After the rubber elastic ring 15 loses the external force restriction, it automatically shrinks and sleeves the external extension bolt rod 11. The bolt rod head 12 can prevent the rubber elastic ring 15 from slipping along the external extension bolt rod 11. The label plate 13 is convenient for experimenters to check information.
[0027] When the utility model is used, first, the culture medium is placed in the dish bottom 1, the sealing top cover 3 is closed, and the bottom of the sealing top cover 3 is pressed against the top of the top cover positioning ring 2. When multiple groups of culture dishes are stacked, the positioning pin rod 5 on the first fixing seat 4 of the lower culture dish is inserted into the positioning pin hole 7 inside the second fixing seat 6 of the upper culture dish, and the upper and lower layers form a nest, which can prevent sliding displacement between the culture dishes. When it is necessary to remove the upper culture dish, the upper culture dish can be directly taken upward, and the upper dish bottom 1 can be moved upward to make the positioning pin rod 5 of the lower layer disengage from the positioning pin hole 7 of the upper layer, or when taking the upper dish bottom 1, the lower sealing top cover 3 can be pressed by the externally extending bolt rod 11 to ensure that the lower sealing top cover 3 is not lifted.
