Description

Technical Field

[0001] This utility model belongs to the technical field of microbial preservation devices, and in particular relates to a microbial culture dish storage device. Background Technology

[0002] Microorganisms are generally cultured in an appropriate amount of stock solution. Petri dishes are used to hold the stock solution and microorganisms. In biological, medical and microbiological experiments, microorganisms need to be sterilized at high temperature and then placed in a ventilated environment to cool naturally before they can be used in experiments.

[0003] In the prior art, patent document with publication number "CN210528921U" discloses a preservation device for agricultural microorganisms, including an outer storage tank. An inner tank is fixedly installed inside the outer storage tank via a heat-insulating mounting base at its bottom. A detachable annular cover is threaded onto the top of the outer storage tank, and a detachable top cover is threaded onto the top of the inner tank. A ventilated groove is located at the center of the top of the detachable top cover, and an embedded end cap located within the inner tank is located at the center of the detachable top cover. This patented technology allows microorganisms to be preserved in a suitable environment. However, in practice, microorganisms often require batch preservation. To achieve this, larger shelves are needed. Existing shelves are mostly constructed from dense components. When culture dishes are placed on the shelf, some components obstruct the surface of the dishes, making it difficult for them to cool down to room temperature quickly and naturally. Utility Model Content

The column is fixedly connected to the shelf. The surface of the shelf is provided with a connecting hole and a positioning clamp. The shelf is also fixedly connected to the ventilation mesh plate, and the ventilation mesh plate covers the connecting hole. The positioning clamp surrounds the connecting hole.

[0006] The connecting hole is a circular through hole, and the ventilation mesh plate is disc-shaped.

[0007] The ventilation mesh is made of stainless steel wire woven in at least two different directions.

[0008] The outer diameter of the stainless steel wire does not exceed 2 mm.

[0009] The positioning clamp includes a first hoop plate, a second hoop plate, a connecting plate, and a locking nut. The first hoop plate is fixedly connected to the layer plate. One side of the second hoop plate is provided with a limiting groove. The other side of the second hoop plate is hinged to one side of the connecting plate. The other side of the connecting plate is hinged to one side of the first hoop plate. The other side of the first hoop plate is fixedly connected to one end of a limiting rod. The other end of the limiting rod is screwed to the locking nut. When the second hoop plate is flipped over and the limiting rod passes through the limiting groove, the microbial culture dish is clamped between the first hoop plate and the second hoop plate.

[0010] The inner wall surface of either the first hoop or the second hoop is bonded with a cushioning pad.

[0011] The first or second hoop plate is semi-circular in shape.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited to the description. This utility model provides a microbial culture dish storage device, such as... Figures 1 to 4 As shown, it includes a support frame 1 and a ventilation mesh plate 2. The support frame 1 includes a column 3 and a shelf 4. The column 3 is fixedly connected to the shelf 4. The surface of the shelf 4 is provided with a connecting hole and a positioning clamp 5. The shelf 4 is also fixedly connected to the ventilation mesh plate 2, and the ventilation mesh plate 2 covers the connecting hole. The positioning clamp 5 surrounds the connecting hole.

[0019] Using the technical solution provided by this utility model, the support frame can be used for the batch preservation of culture dishes and microorganisms. When the culture dish is clamped in the positioning fixture, the surface of the shelf is provided with connecting holes, which are covered by the ventilation mesh plate. This not only keeps the culture dish in a stable supporting posture, but also avoids the shelf plate from blocking the surface of the culture dish, allowing the air to fully contact the culture dish, thereby enabling the airflow to fully exchange heat with the culture dish and allowing the culture dish to quickly and naturally ventilate and cool down to room temperature.

[0020] Specifically, the connecting hole is a circular through hole, and the ventilation mesh plate 2 is disc-shaped. The ventilation mesh plate 2 is made of stainless steel wire woven in at least two different directions. The outer diameter of the stainless steel wire does not exceed 2mm.

[0021] In addition, the positioning clamp 5 includes a first hoop plate 6, a second hoop plate 7, a connecting plate 8, and a locking nut 9. The first hoop plate 6 is fixedly connected to the shelf 4. One side of the second hoop plate 7 is provided with a limiting groove 10, and the other side of the second hoop plate 7 is hinged to one side of the connecting plate 8. The other side of the connecting plate 8 is hinged to one side of the first hoop plate 6. The other side of the first hoop plate 6 is fixedly connected to one end of the limiting rod 11, and the other end of the limiting rod 11 is screwed to the locking nut 9. When the second hoop plate 7 is flipped over and the limiting rod 11 passes through the limiting groove 10, the microbial culture dish is clamped between the first hoop plate 6 and the second hoop plate 7. By using the technical solution of this utility model, the culture dish is clamped by the positioning clamp, so that the culture dish can be stably clamped on the surface of the shelf. Furthermore, the surfaces of the first hoop plate 6 and the second hoop plate 7 are also provided with an appropriate number of ventilation holes, so that the culture dish can fully contact the airflow of the external environment for heat exchange, and the culture dish can be quickly and naturally cooled to room temperature.

[0022] Specifically, the inner wall surface of either the first hoop 6 or the second hoop 7 is adhered with a cushioning pad. Using the technical solution of this utility model, the cushioning pad is elastic and provides a buffering effect on the force applied to the culture dish. When moving the support frame and the culture dish, the culture dish can maintain a stable clamping position and posture, preventing damage to the surface of the culture dish.

[0023] Furthermore, the first hoop 6 or the second hoop 7 is generally semi-circular. The limiting groove 10 is a U-shaped opening groove provided at the edge of the second hoop 7.

[0024] Specifically, the support frame 1 also includes limiting screws 12, and the surface of the column 3 is provided with several positioning holes 13. The limiting screws 12 are screwed around the perimeter of the shelf 4, and the limiting screws 12 pass through at least one positioning hole 13. The surface of the column 3 is also marked with scale lines 14. Using the technical solution of this utility model, the positioning holes 13 are distributed in a linear array along the axial direction of the column 3. By adjusting the limiting screws to pass through different positioning holes, the corresponding shelf spacing can be adjusted.
