Description

Technical Field

[0001] This utility model relates to a petri dish, specifically a multi-layer microbial petri dish, and belongs to the field of petri dish technology. Background Technology

[0002] In experiments such as microbial strain screening, drug sensitivity testing, and colony counting, petri dishes are the core tools for supporting microbial growth. Stable culture environments and efficient space utilization are necessary to ensure experimental accuracy and efficiency.

[0003] However, microbial experiments often require the simultaneous cultivation of multiple samples. Each culture dish needs to be placed independently on the lab bench or incubator. If multiple samples are cultivated simultaneously, a large area is required. When laboratory space is limited, batch cultivation is necessary, which can easily prolong the experimental cycle. Furthermore, single-layer culture dishes do not have a fixed positioning structure and are easily displaced when moved or placed, leading to confusion in colony counting and observation. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer microbial culture dish to solve the above problems. It transforms the traditional planar distribution of single-layer culture dishes into a vertical three-dimensional layout. Multiple independent culture dishes can be stably stacked in the same experimental table or incubator space as a single culture dish, thus increasing the number of samples cultured simultaneously. Each turntable can rotate freely, and there is no need to move the upper layer device when picking up or placing any layer of culture dish, avoiding contact and interference with other culture dishes during the picking and placing process.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a multi-layer microbial culture dish, including a turntable, several turntables are stacked sequentially on a support mechanism, a storage mechanism is engaged and installed inside the turntable, the storage mechanism includes a rubber pad and a through groove, the bottom end of the turntable is provided with a through groove, a culture dish is engaged and installed inside the turntable, a cover plate is engaged and connected to the top of the culture dish, a rubber pad is adhered to the side wall of the culture dish, a protrusion is adhered to the side wall of the turntable, and a groove is provided on the part of the turntable near the rubber pad.

[0006] Preferably, the inner diameter of the turntable is equal to the diameter of the culture dish and the cover plate, and the protrusions and rubber pads are both arranged in an arc-shaped structure.

[0007] Preferably, the height of the turntable near the groove is lower than the height of the turntable near the protrusion, and the arc length of the rubber pad is less than the arc length of the groove.

[0008] Preferably, the support mechanism includes a base plate and insert rods, with insert rods passing through a plurality of insert rods, the bottom end of each insert rod being fixedly connected to the base plate, and a vertical pole being fixedly connected to the part of the base plate opposite to the insert rod.

[0009] Preferably, the support mechanism further includes a stop bar, and the stop bar is sleeved on the insert rod and the upright rod, and a positioning block is threadedly connected to the insert rod and the upright rod.

[0010] Preferably, the end of the turntable away from the upright is rotatably connected to the insert rod, and the diameters of the insert rod and the upright are equal.

[0011] Preferably, the abutment is located at the end of the insert or upright that is away from the base plate, and the positioning block abuts against the top of the abutment.

[0012] Preferably, a turntable near the bottom of the insertion rod is rotatably connected to the base plate, and a turntable near the top of the insertion rod is rotatably connected to the abutment rod.

[0013] The beneficial effects of this utility model are as follows: Through the stacking design, multiple turntables can be placed on the same support mechanism, each turntable independently supporting a culture dish, which is particularly suitable for laboratory scenarios with limited space and the need for batch cultivation of microorganisms; the support mechanism provides vertical support for the multiple turntables, avoiding the problem of easy tipping when culture dishes are directly stacked; the turntables are rotatably connected to the support mechanism, allowing each layer to rotate independently, enabling the placement and removal of any layer of culture dishes without moving the entire device, making operation convenient; the turntables partially isolate the culture dishes from the external environment, preventing dust and bacteria from falling into the culture dishes during open placement; the independent separation of multiple turntables effectively prevents condensate from the upper culture dishes from dripping onto the lower layer, avoiding cross-contamination; the cover plate fits tightly against the culture dish, effectively blocking external bacteria from entering, reducing evaporation of culture medium moisture, maintaining stable humidity of the culture medium, and ensuring normal microbial growth; the protrusions provide convenient force application points for rotating the turntable, allowing operators to easily rotate the turntable and quickly locate the target culture dish; the rubber pads facilitate the removal of culture dishes from the turntable.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 As shown, a multi-layer microbial culture dish includes a turntable 2, with several turntables 2 stacked sequentially on a support mechanism 1. A storage mechanism 3 is fitted inside each turntable 2. The storage mechanism 3 includes a rubber pad 304 and a through groove 306. The bottom end of the turntable 2 has the through groove 306. A culture dish 303 is fitted inside the turntable 2, and a cover plate 305 is fitted to the top of the culture dish 303. The cover plate 305 is aligned with the top of the culture dish 303, and a light pressure achieves a tight seal. The cover plate 305 fits tightly against the culture dish 303 to prevent the entry of external microorganisms. A rubber pad 304 is adhered to the side wall of the culture dish 303, and a protrusion 301 is adhered to the side wall of the turntable 2. A groove 302 is provided on the turntable 2 near the rubber pad 304 to hold the culture dish. The culture dish 303 containing the culture medium and microbial sample is placed vertically into the turntable 2. Because the inner diameter of the turntable 2 is equal to the diameter of the culture dish 303, the culture dish 303 will precisely fit in the center of the turntable 2. The rubber pad 304 on the side wall is aligned with the groove 302 provided in the turntable 2. The inner diameter of the turntable 2 is equal to the diameter of the culture dish 303 and the cover plate 305. The protrusion 301 and the rubber pad 304 are both arc-shaped structures. The height of the part of the turntable 2 near the groove 302 is lower than the height of the part of the turntable 2 near the protrusion 301. When it is necessary to remove a certain layer of culture dish 303, hold the protrusion 301 on the side wall of the turntable 2 with your finger and rotate the turntable 2 to an angle that is easy to operate, and the culture dish 303 can be removed from the turntable 2. The arc length of the rubber pad 304 is less than the arc length of the groove 302.

[0022] As a technical optimization of this utility model, the support mechanism 1 includes a base plate 101 and insert rods 102. A plurality of insert rods 102 are inserted through the base plate 101. The bottom end of each insert rod 102 is fixedly connected to the base plate 101. A vertical rod 105 is fixedly connected to the base plate 101 away from the insert rods 102. By vertically fixing the bottom end of the insert rods 102 to the base plate 101 and symmetrically installing the vertical rods 105 on the side of the base plate 101 away from the insert rods 102, a stable double-rod support frame can be formed. The base plate 101 can also increase the contact area, preventing overall tipping. A stop rod 104 is sleeved on the insert rods 102 and the vertical rod 105. A positioning block 103 is threaded onto the insert rods 102 and the vertical rod 105. The end of the turntable 2 away from the vertical rod 105 is connected to the insert rod. The insert rod 102 and the upright rod 105 are rotatably connected. The diameters of the insert rod 102 and the upright rod 105 are equal. The abutment rod 104 is located at the end of the insert rod 102 and the upright rod 105 away from the base plate 101. The positioning block 103 abuts against the top of the abutment rod 104. The abutment rod 104 is sleeved on the top of the insert rod 102 and the upright rod 105, covering the top turntable 2. Then the positioning block 103 is threaded onto the insert rod 102 and the upright rod 105. The positioning block 103 is rotated clockwise until it abuts against the top of the abutment rod 104. The pressure of the positioning block 103 fixes the abutment rod 104, thereby limiting the vertical displacement of the multi-layer turntable 2, and the assembly can be completed. One turntable 2 near the bottom of the insert rod 102 is rotatably connected to the base plate 101, and one turntable 2 near the top of the insert rod 102 is rotatably connected to the abutment rod 104.

[0023] In use, this utility model first vertically fixes the bottom end of the insertion rod 102 onto the base plate 101. Then, the uprights 105 are symmetrically installed on the side of the base plate 101 away from the insertion rod 102, forming a stable double-rod support frame. This also increases the contact area of ​​the base plate 101, preventing overall tipping. After fixing, several turntables 2 are sequentially fitted onto the insertion rod 102, allowing each layer of turntables 2 to rotate freely around the insertion rod 102. The first layer of turntables 2 closest to the base plate 101 can... The bottom plate 101 is rotatably connected to ensure the stability of the bottom layer; then the abutment rod 104 is sleeved on the top of the insert rod 102 and the upright rod 105, covering the top turntable 2; then the positioning block 103 is threaded onto the insert rod 102 and the upright rod 105, and the positioning block 103 is rotated clockwise until it abuts against the top of the abutment rod 104. The pressure of the positioning block 103 fixes the abutment rod 104, thereby limiting the vertical displacement of the multi-layer turntable 2, and the assembly is completed; the cover plate 305 is aligned with the culture medium. The top of the petri dish 303 can be lightly pressed to achieve a snap-fit ​​seal, and the cover plate 305 fits tightly against the petri dish 303 to prevent the entry of external bacteria. The petri dish 303, containing culture medium and microbial samples, is then vertically placed into the turntable 2. Because the inner diameter of the turntable 2 is equal to the diameter of the petri dish 303, the petri dish 303 will precisely snap into the center of the turntable 2, with the side wall rubber pad 304 aligned with the groove 302 inside the turntable 2. To remove a specific layer of petri dish 303, hold the protrusion 301 on the side wall of the turntable 2 with your finger and rotate the turntable 2 to a convenient angle to remove the petri dish 303 from the turntable 2. During the culture process, the through groove 306 at the bottom of the turntable 2 allows for interlayer air circulation, maintaining a stable culture environment. For periodic observation, rotate the target layer turntable 2 and open the cover plate 305 to observe the colony growth status without removing the petri dish 303, reducing the risk of exposure to contamination. After the experiment, simply pull the petri dish 303 upwards to remove it from the turntable 2.
