Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of microbial culture dish racks, and in particular to a foldable microbial culture dish rack. Background Technology
[0002] Petri dishes are commonly used in microbial culture experiments. Multiple petri dishes are usually needed to culture various microorganisms, so a petri dish rack is required to store them. Larger petri dishes are usually placed vertically to avoid taking up too much space and improve space utilization.
[0003] In existing technologies, vertical petri dish racks typically have grooves cut into the rack body, and the petri dishes are then inserted circumferentially into the grooves to lock them in place and secure them. However, the fixed width of the grooves makes it difficult to directly secure the petri dishes, which can easily lead to them falling off and colliding, thus affecting the microbial experiments conducted on the petri dishes. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a foldable microbial culture dish rack in order to solve the technical problems mentioned in the background art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A foldable microbial culture dish rack includes a number of placement plates. Two slots are formed on the opposite side walls of two adjacent placement plates. The slots are designed to be closed. A placement element is provided between the two corresponding slots for placing culture dishes. A limiting element is provided between two adjacent placement plates for fixing the placed culture dishes.
[0007] In a preferred embodiment, the present invention can be further configured such that: the placement component includes a sliding ring, a sliding piece is slidably connected in the slot, a support rod is fixedly connected between two corresponding sliding rings, and a separator ring is fixedly connected to the middle of the outer periphery of the support rod.
[0008] In a preferred embodiment, the present invention can be further configured such that: both ends of the support rod are provided with recessed holes, and a positioning spring is fixedly connected to the inner end sidewall of the recessed hole, with the end of the positioning spring being fixedly connected to the inner end sidewall of the slot.
[0009] In a preferred embodiment, the present invention can be further configured such that: an annular groove is formed on the side of the placement plate at the position of the slot, and the size of the annular groove is the same as the size of the separator ring.
[0010] In a preferred embodiment, the present invention can be further configured such that the limiting member includes a fixing rod, the fixing rod is fixedly connected to the top side of the placement plate, and a flexible limiting plate is fixedly connected to the side of the fixing rod.
[0011] In summary, this utility model has at least one of the following beneficial technical effects:
[0012] 1. This foldable microbial culture dish rack allows for the placement of culture dishes between any two placement plates. The rack is positioned using a separator ring and the side wall of the placement plate. The sliding support rod and separator plate work together with the placement plate to adjust the placement spacing, facilitating the placement of various culture dishes. It also clamps and positions the culture dishes to prevent them from falling off.
[0013] 2. This foldable microbial culture dish rack utilizes a fixing rod and a flexible plate on the placement plate to further position the culture dish, improving the stability of the culture dish after it is clamped and positioned. This prevents the bottom of the culture dish from touching the top of the culture dish after it is clamped and positioned, thus preventing the culture dish from falling off the support rod and being damaged by impact. This achieves the effect of protecting the culture dish. In addition, the flexible limiting plate is made of rubber or silicone. After the flexible limiting plate clamps the culture dish, it deforms, increasing the contact area between the plate and the culture dish and improving stability. Attached Figure Description

Detailed Implementation
[0020] The present invention will be further described in detail below with reference to the accompanying drawings.
[0021] Example:
[0022] Reference Figures 1-4 The present invention discloses a foldable microbial culture dish rack, comprising a number of placement plates 1, two slots 2 are formed on the opposite side walls of two adjacent placement plates 1, the slots 2 are closed, a placement member 3 is provided between the corresponding two slots 2 for placing the culture dish, and a limiting member 4 is provided between two adjacent placement plates 1 for fixing the placed culture dish.
[0023] In this embodiment, reference Figure 1 and Figure 2 In use, pulling one of the placement plates 1 causes the placement component 3 to unfold, simultaneously unfolding the limiting component 4. The culture dish can then be inserted between the two corresponding placement plates 1, with the circumferential side of the culture dish adhering to the limiting component 4. The culture dish is then secured by the placement component 3, ensuring stable placement between the two corresponding placement plates 1. The placement component 3 further stabilizes the culture dish, allowing various sizes of culture dishes to be placed within it. This achieves the adaptive adjustment effect of the culture dish rack, facilitating the placement of culture dishes. The limiting component 4, in conjunction with the placement component 3, further holds the culture dish after placement, improving its stability and preventing it from detaching upon contact.
[0024] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the placement component 3 includes a sliding ring 5, a sliding piece is slidably connected in the slot 2, a support rod 6 is fixedly connected between two corresponding sliding rings 5, a partition ring 7 is fixedly connected to the middle of the outer periphery of the support rod 6, and an annular groove 10 is opened on the side of the placement plate 1 at the position of the slot 2, the size of the annular groove 10 is the same as the size of the partition ring 7.
[0025] In this embodiment, reference Figure 3 When one of the placement plates 1 is pulled, the support rod 6 slides in the slot 2. Then, when the culture dish is placed between the two corresponding placement plates 1, the circumferential side of the culture dish is attached to the two corresponding support rods 6, while the circular side of the culture dish has a separator ring 7 that is attached to the side wall of the placement plate 1, which restricts the culture dish and achieves the effect of convenient placement of the culture dish. At the same time, when the placement plate 1 is pulled, it can be adapted to multiple models of culture dishes according to the distance the support rod 6 is pulled out.
[0026] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 4As shown, both ends of the support rod 6 are provided with recessed holes 8, and a positioning spring 9 is fixedly connected to the inner end side wall of the recessed hole 8. The end of the positioning spring 9 is fixedly connected to the inner end side wall of the slot 2.
[0027] In this embodiment, reference Figure 3 and Figure 4 Both ends of the support rod 6 have recessed holes 8. The inner end sidewall of the recessed hole 8 is fixedly connected to the positioning spring 9, and the end of the positioning spring 9 is fixedly connected to the inner end sidewall of the slot 2. When the placement plate 1 is pulled open, the support rod 6 is exposed, which will cause the positioning spring 9 to be pulled. After the culture dish is placed on the support rod 6, the placement plate 1 is released, and the positioning spring 9 will retract. When the positioning spring 9 retracts, it pulls the sliding of the placement plate 1, so that the placement plate 1 works with the separator ring 7 to clamp the culture dish. Thus, the stability of the culture dish after placement is improved by the clamping of the placement plate 1 and the separator ring 7.
[0028] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the limiting member 4 includes a fixing rod 11, which is fixedly connected to the top side of the placement plate 1, and a flexible limiting plate 12 is fixedly connected to the side of the fixing rod 11.
[0029] In this embodiment, reference Figure 1 and Figure 2 When the culture dish is placed between the corresponding placement plate 1 and the separator ring 7, the fixing rod 11 and the flexible plate on the placement plate 1 are used to further position the culture dish, which improves the stability of the culture dish after it is clamped and positioned. This prevents the bottom of the culture dish from touching the top of the culture dish after it is clamped and positioned, which would cause the culture dish to fall off the support rod 6 and be damaged by collision. This achieves the effect of protecting the culture dish. In addition, the flexible limiting plate 12 is made of rubber or silicone. After the flexible limiting plate 12 clamps the culture dish, it deforms, which increases the contact area between the plate and the culture dish and improves the stability.
[0030] The implementation principle of the above embodiment is as follows: when one of the placement plates 1 is pulled, the placement component 3 is unfolded when the placement plate 1 moves, and the limiting component 4 is also unfolded. The culture dish can then be inserted between the two corresponding placement plates 1. When one of the placement plates 1 is pulled, the support rod 6 slides in the slot 2. Then, when the culture dish is placed between the two corresponding placement plates 1, the circumferential side of the culture dish is attached to the two corresponding support rods 6, while the circular side of the culture dish has a partition ring 7 that is attached to the side wall of the placement plate 1 to limit the culture dish, thus achieving the effect of convenient placement of the culture dish. At the same time, when the placement plate 1 is pulled, it can adapt to multiple models of culture dishes according to the distance the support rod 6 is pulled out.
[0031] When the placement plate 1 is pulled open, the support rod 6 is exposed, which causes the positioning spring 9 to be pulled. After the culture dish is placed on the support rod 6, the placement plate 1 is released, and the positioning spring 9 will retract. When the positioning spring 9 retracts, it pulls the sliding of the placement plate 1, allowing the placement plate 1 to work with the separator ring 7 to clamp the culture dish. Thus, the stability of the culture dish after placement is improved by the clamping of the placement plate 1 and the separator ring 7.
[0032] When the culture dish is placed between the corresponding placement plate 1 and the separator ring 7, the fixing rod 11 and the flexible plate on the placement plate 1 are used to further position the culture dish, which improves the stability of the culture dish after it is clamped and positioned. This prevents the bottom of the culture dish from touching the top of the culture dish after it is clamped and positioned, which would cause the culture dish to fall off the support rod 6 and be damaged by collision. This achieves the effect of protecting the culture dish. In addition, the flexible limiting plate 12 is made of rubber or silicone. After the flexible limiting plate 12 clamps the culture dish, it deforms, which increases the contact area between the plate and the culture dish and improves the stability.
[0033] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
