Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a petri dish rack. Background Technology

[0002] In biological, medical and microbiological experiments, petri dishes are the core tools for carrying cell and microbial cultures. Their storage and management directly affect experimental efficiency and sample safety. With the expansion of experimental scale and the increase in automation requirements, the requirements for the stability, compatibility, ease of cleaning and space utilization of the placement racks are gradually increasing.

[0003] In the existing technology, the petri dish rack has the following problems when in use:

[0004] First, it is inconvenient to remove the petri dish from the placement opening of the container;

[0005] Secondly, the rack occupies a large amount of indoor space when placed in the laboratory, regardless of whether petri dishes are placed on it, and the rack is difficult to move and is not lightweight or flexible. Utility Model Content

[0006] The purpose of this utility model is to provide a petri dish rack that not only has the advantage of convenient petri dish placement and retrieval, but also facilitates storage and organization, and effectively saves space.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a petri dish placement rack, including a base, a support column fixedly disposed on the base, a placement mechanism fixedly disposed on the side of the support column, a plurality of culture units disposed on the placement mechanism, and a lifting mechanism for facilitating the lifting of the petri dish at the bottom of the culture unit.

[0008] By adopting the above technical solution, the bottom of the culture unit is provided with a lifting mechanism to facilitate the removal of the culture dish placed in the culture unit, so as to avoid the culture dish getting stuck in the culture unit and being unable to be removed.

[0009] A further feature of this invention is that the placement mechanism includes a telescopic frame and crossbars rotatably connected to both ends of the telescopic frame. The telescopic frame includes several sets of scissor arms that are rotatably connected in a cross manner. The scissor arms are rotatably connected at their endpoints by pins and at their midpoints by hollow shafts.

[0010] By adopting the above technical solution, the placement mechanism adopts a telescopic frame structure, which is convenient for stretching and shrinking. When the placement mechanism is not needed, it can be shrunk without occupying extra space.

[0011] A further feature of this invention is that the material of the telescopic frame is a ferromagnetic material, and the material of the telescopic frame is one of stainless steel, cast iron or magnetic alloy.

[0012] A further feature of this invention is that the culture unit includes a placement box, the upper part of which has a plurality of placement openings for placing culture dishes, and the bottom of the placement openings has vertical holes.

[0013] A further feature of this invention is that a magnet is fixedly provided on the bottom surface of the box, and the position of the magnet on the bottom surface of the box coincides with the position of the lower telescopic frame and has the same width.

[0014] By adopting the above technical solution, the bottom surface of the placement box is equipped with a magnet that is magnetic and can attract the telescopic frame below, making it easy to install and fix the placement box. The position of the magnet on the bottom surface of the placement box coincides with the position of the telescopic frame below and the width is the same, which can save magnets and allow the magnet on the bottom surface of the placement box to be attracted to the telescopic frame.

[0015] A further feature of this invention is that the lifting mechanism includes a top plate disposed on the bottom surface of the placement opening, and a vertical support located in the vertical hole is fixedly connected to the lower part of the top plate.

[0016] By adopting the above technical solution, the vertical support is located in the vertical hole at the bottom of the placement opening. When it is necessary to take out the culture dish from the placement box, the vertical support can be pushed up from the bottom surface of the vertical support with a finger, so that the top plate can lift the culture dish.

[0017] A further feature of this invention is that a storage mechanism is fixedly provided on the side of the support column. The storage mechanism includes a storage box for storing the box. The storage box has several partitions inside and several push-open windows are provided on both sides of the storage box.

[0018] By adopting the above technical solution, the storage box is used to store the placement box that does not contain the petri dish. Several partitions divide the box into several compartments. Each compartment has a push window on both sides for pushing the box out. The storage box makes full use of vertical space.

[0019] A further feature of this invention is that the bottom of the base is provided with four equally spaced casters.

[0020] By adopting the above technical solution, the entire frame can be moved easily and with minimal effort. Furthermore, the casters are evenly spaced, ensuring uniform force distribution and preventing the frame from tipping over during movement.

[0021] The beneficial effects of this utility model are:

[0022] 1. The bottom of the culture unit of this application is provided with a lifting mechanism. The lifting mechanism is fixedly connected to the top plate and the vertical support. When it is necessary to take out the culture dish, the top plate can easily lift the culture dish after the vertical support is pushed up by hand, making it easy to take out and put in, thus improving the convenience of taking out the culture dish.

[0023] 2. The placement mechanism adopts a telescopic scissor arm structure, with the scissor arms rotating and connected, which facilitates retraction and extension. When in use, it can be extended to the required position, and when not in use, it can be retracted, which greatly saves space. The omnidirectional wheels make the whole frame easy to move and flexible to use.

[0024] 3. The magnet on the bottom of the box is precisely attached to the telescopic frame, which is convenient for installation and fixation, and also saves magnet materials.

[0025] 4. The storage mechanism can accommodate containers without petri dishes, making full use of vertical space and reducing space occupation when not in use. Attached Figure Description

[0037] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0038] like Figures 1 to 3 As shown, this utility model provides a petri dish placement rack, including a base 1, a support column 2 fixedly disposed on the base 1, and several layers of placement mechanisms 3 fixedly disposed on the side of the support column 2. Several culture units 4 are disposed on each layer of placement mechanism 3, and each culture unit 4 is provided with a lifting mechanism 5 at the bottom to facilitate lifting the petri dish, so as to facilitate the removal of the petri dish placed in the culture unit 4 and avoid the petri dish getting stuck in the culture unit 4 and unable to be removed.

[0039] It is worth noting that the height of support column 2 is lower than the average height of a normal human body, making it easier for experimental personnel to operate.

[0040] Furthermore, the base 1 is equipped with four casters 8 at the bottom, which makes it easy to move the entire frame, saving effort. The casters 8 are evenly spaced, so the force is evenly distributed and the frame will not tip over during movement.

[0041] Furthermore, such as Figure 4 As shown, the placement mechanism 3 includes a telescopic frame 301 and crossbars 302 rotatably connected to both ends of the telescopic frame 301. The telescopic frame 301 includes several sets of scissor arms 303 that are rotatably connected in a cross manner.

[0042] Furthermore, the scissor arms 303 are rotatably connected at their endpoints via pins 304, and at their midpoints via hollow shafts 305, with several sets of scissor arms 303 connected sequentially.

[0043] Specifically, the placement mechanism 3 adopts the structure of a telescopic frame 301, which is easy to stretch and shrink. When the placement mechanism 3 is needed to place the culture dish, the telescopic frame 301 is stretched to the required position by hand.

[0044] When the placement mechanism 3 is not needed, the telescopic frame 301 can be manually pushed to retract, so that the placement mechanism 3 does not occupy extra space due to the extension of the telescopic frame 301.

[0045] The telescopic frame 301 is rotatably connected to crossbars 302 at both ends. The crossbar 302 at either end is fixedly connected to the support column 2. The crossbars 302 at both ends can limit the displacement of the telescopic frame 301 in the non-stretching and non-contraction directions, making the overall structure more stable when the placement mechanism 3 stretches or contracts, less prone to deformation and shaking, and ensuring the safety of the petri dish placement.

[0046] Specifically, the telescopic frame 301 is made of ferromagnetic material, preferably stainless steel, cast iron or magnetic alloy.

[0047] Furthermore, such as Figures 5 to 7 As shown, the culture unit 4 includes a placement box 401. The upper part of the placement box 401 has several placement openings 402 for placing culture dishes. The bottom of the placement openings 402 has vertical holes 403. A magnet 405 is fixedly installed on the bottom surface of the placement box 401.

[0048] Specifically, the bottom surface of the placement box 401 is provided with a magnet 405, which is magnetic and can attract the telescopic frame 301 below, making it easy to install and fix the placement box 401. It is worth noting that the position of the magnet 405 on the bottom surface of the placement box 401 coincides with the position of the telescopic frame 301 below and has the same width, which can save magnet 405 and make the magnet 405 on the bottom surface of the placement box 401 attract the telescopic frame 301.

[0049] Furthermore, the lifting mechanism 5 includes a top plate 501 disposed on the bottom surface of the placement port 402, and a vertical support 502 located in the vertical hole 403 is fixedly connected to the lower part of the top plate 501.

[0050] It is worth noting that the bottom surface of the vertical support 502 should be offset from the position of the scissor arm 303 below the placement box 401. This is to prevent the vertical support 502 from being blocked by the scissor arm 303 when the placement box 401 is attached to the telescopic frame 301, thus preventing fingers from pushing the vertical support 502 up from below. To solve this problem, the placement opening 402 can be positioned as close as possible to the center of the placement box 401. Figure 9 .

[0051] Of course, you can also first remove the placement box 401 containing the culture dish from the telescopic frame 301, and then use your fingers to push the vertical support 502 up from the bottom, so that the top plate 501 can lift the culture dish.

[0052] Furthermore, a storage mechanism 7 is fixedly installed on the side of the support column 2. The storage mechanism 7 includes a storage box 701 for storing the box 401. The storage box 701 has several partitions 702 inside, and several push-open windows 703 are opened on both sides of the storage box 701.

[0053] Furthermore, the storage box 701 is used to store the placement box 401 that does not contain a petri dish. Several partitions 702 divide the space into several compartments for placing the placement box 401. Each compartment has a push window 703 on both sides for pushing the placement box 401 out. The design of the storage box 701 makes full use of vertical space.

[0054] The above describes the basic principles, main features, and advantages of this utility model. The standard parts used in this utility model can all be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, which will not be described in detail here.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
