Description

Technical Field

[0001] This utility model relates to the field of biological experimental equipment technology, specifically a pull-out culture dish combination support. Background Technology

[0002] Molecular biology is the science that studies life phenomena at the molecular level. It elucidates the essence of various life phenomena by studying the structure, function, and biosynthesis of biological macromolecules. Its research content includes various life processes, and experiments require the use of petri dishes for cultivation. Because unstable experimental environments can easily lead to data deviations and affect the accuracy of experimental data, petri dishes are usually placed in an incubator with a constant and controllable culture environment.

[0003] Current incubators use partitions to divide the storage space into multiple vertical storage compartments, and petri dishes typically need to be stacked on the partitions to meet the required number of dishes. When stacking petri dishes, moving adjacent dishes when retrieving a specific dish can cause shaking and liquid leakage. Although the supporting area can be increased by adding more partitions, the small spacing between the partitions makes it inconvenient to retrieve and place petri dishes. Furthermore, incubators often contain containers of different heights, such as culture media, reagent bottles, and test tube racks, which are not suitable for small-spaced partitions. Frequent disassembly and reassembly of partitions to adjust the spacing is necessary, which is cumbersome and reduces experimental efficiency.

[0004] Based on the above problems, a pull-out culture dish combination support suitable for incubators is proposed, which can place culture dishes in layers according to the spacing of the partitions, thereby increasing the number of culture dishes that can be held. Utility Model Content

[0005] This invention provides a pull-out culture dish combination support, which allows culture dishes to be placed in layers according to the spacing of the incubator partitions, increasing the number of culture dishes that can be held; and it can simultaneously and stably move multiple culture dishes to the microscope stage for observation, reducing the shaking of the culture dishes and lowering the risk of liquid leakage.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model solves the above-mentioned problems through the following technical solution:

[0007] A pull-out petri dish assembly support includes multiple rectangular support frames stacked longitudinally. Each support frame has a corresponding positioning platform and positioning groove at its upper and lower ends, and the upper and lower support frames are positioned by interlocking the positioning platforms and positioning grooves. The inner side of each support frame has corresponding sliding grooves, into which a petri dish tray is horizontally inserted. The petri dish tray has multiple petri dish placement slots along its length, and the bottom of each slot has a hollow structure with a central through-hole in the middle for a finger to pass through and lift the petri dish upwards.

[0008] Furthermore, the hollow structure includes a placement ring located in the middle, which is connected to the inner wall of the culture dish placement tank by a placement rod arranged along the circumference; the central through hole is an annular hole formed by the inner ring of the placement ring.

[0009] Furthermore, the groove opening is provided with a guide angle to guide the culture dish tray into the groove.

[0010] Furthermore, the outer end of the culture dish tray is provided with a handle for easy pulling out of the tray.

[0011] Furthermore, the upper and lower end faces of the support frame are closed, and the positioning platform and positioning groove are respectively set in the middle of the lower end face and the upper end face of the support frame. The cross-sectional area of ​​the positioning platform is 2 / 3 to 3 / 4 of the frontal projection area of ​​the support frame.

[0012] The advantages and effects of this utility model are:

[0013] 1. The present invention discloses a pull-out petri dish combination support, which is constructed by stacking multiple support frames, with petri dish trays inserted into sliding grooves on the inner wall of the support frames. The stacking height of the support frames can be flexibly configured according to the gap height of the incubator partitions, avoiding the problem of disordered placement and difficulty in retrieving petri dishes due to excessive placement. Simultaneously, the tray design also prevents shaking and spillage caused by moving adjacent petri dishes when retrieving a target petri dish, reducing the risk of incubator contamination.

[0014] 2. In the design, the petri dishes are placed in the petri dish placement slots on the petri dish tray. The bottom of the petri dish is supported by a hollow structure. The experimenter can use their fingers to lift the petri dish out of the placement slot through the central through hole. This design makes it easy to pick up and put down the petri dishes.

[0015] 3. Existing microscopes are often equipped with large stages, allowing the culture dishes to be placed directly on the stage without removing them from the tray. The culture dish tray can then be observed through the perforated structure. This structure allows multiple culture dishes to be moved simultaneously, reducing the risk of shaking when handling individual dishes. Attached Figure Description

[0020] The present invention will be further described below with reference to the embodiments, but the present invention is not limited to these embodiments.

[0021] The pull-out culture dish assembly support described in this embodiment is as follows: Figure 1-3 As shown, the system includes three rectangular support frames 1 stacked vertically. The upper and lower ends of each support frame 1 are closed. A positioning groove 13 is formed on the upper end of each support frame 1, and a corresponding positioning platform 12 is provided on the lower end. The upper and lower support frames 1 are positioned by interlocking the positioning platform 12 and the positioning groove 13. In this embodiment, the positioning platform 12 is located at the middle of the bottom end of the support frame 1, and its cross-sectional area is 2 / 3 to 3 / 4 of the projected area of ​​the support frame 1. This allows the positioning platform 12 of the bottom support frame 1 to have a large and stable contact with the partition of the incubator, without affecting the stability of the combined support structure.

[0022] In this embodiment, each support frame 1 has a set of corresponding left and right sliding grooves 11 on its inner side, and the culture dish tray 2 is horizontally inserted into the sliding groove 11. Of course, each support frame 1 can be provided with multiple sets of longitudinally arranged sliding grooves 11 as needed. The groove opening of the sliding groove 11 is provided with a guide angle 14 to guide the culture dish tray 2 to slide in, which helps to simplify the cooperation efficiency between the culture dish tray 2 and the sliding groove 11. The outer end of the culture dish tray 2 is provided with a handle 25 for easy pulling out of the tray.

[0023] The petri dish tray 2 has three petri dish placement slots 21 along its length, the size of which matches the size of the petri dish 3 to be placed. The bottom of the petri dish placement slot 21 has a hollow structure, including a placement ring 23 in the middle and placement rods 24 connecting the placement ring 23 and the inner wall of the petri dish placement slot 21. Multiple placement rods 24 are arranged along the circumference of the placement ring 23. The inner ring of the placement ring 23 forms a central through-hole 22 through which a finger can pass and lift the petri dish 3 upwards. The central through-hole 22 also provides a large window for observing the culture, ensuring a good field of view.

[0024] Using the pull-out culture dish combination support described in this embodiment, the number of support frames 1 stacked can be selected according to the height of the gap between the incubator partitions. After placing the culture dish 3 in the culture dish placement slot 21 of the culture dish tray 2, the culture dish tray 2 is inserted into the sliding groove 11 of the support frame 1. Multiple culture dishes 3 in the same group of experiments can be placed on the same culture dish tray 2. During observation, the culture dish tray 2 can be placed directly on the stage, and the cultures in multiple culture dishes 3 can be observed sequentially, avoiding the risk of liquid leakage caused by repeatedly moving a single culture dish 3.

[0025] The perforated structure provides a field of view, and after observation, the experimenter can use their fingers to lift the culture dish 3 out of the placement slot 21 through the central through-hole 22. The combined support described in this embodiment can flexibly adapt to the placement of culture dishes in incubators of different sizes, and can reduce the risk of liquid leakage when moving culture dishes to a certain extent, simplifying the operation of picking up and placing culture dishes.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations of these embodiments without departing from the principles and spirit of this utility model still fall within the protection scope of this utility model.
