Abstract
Description
Technical Field
[0001] This invention belongs to the field of microbial research technology, and more specifically, relates to a microbial sample preservation device. Background Technology
[0002] A microbial sample preservation device is a container or device specifically designed for storing and transporting microbial samples. The main purpose of such devices is to maintain the activity, integrity, and purity of microbial samples over a specific period, ensuring they can be accurately analyzed and studied under laboratory conditions. Existing microbial sample preservation devices typically employ a box-like structure to store microbial culture dishes, with a circular lid on top to ensure the preservation of microbial samples and prevent contamination.
[0003] Based on the above, while existing microbial sample preservation devices typically employ a box-like structure to store microbial culture dishes, equipped with a circular lid on top to ensure the preservation of microbial samples and prevent contamination, they exhibit several significant drawbacks in practical operation. Particularly when the lid is removed, atmospheric pressure often causes the lid and sample box to move upwards, potentially leading to the tipping or destruction of the microbial samples inside. This design flaw not only increases the risk of sample damage, affecting the accuracy and reliability of experimental results, but also causes operational inconvenience for users, especially when frequent opening and closing of the preservation device is required, significantly limiting work efficiency and sample processing flexibility. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a microbial sample preservation device to solve the problem that when the lid of an existing microbial sample preservation device is removed, atmospheric pressure causes the lid and sample box to move upwards together, resulting in the microbial sample inside the sample box being overturned or destroyed.
[0005] The purpose and effectiveness of this utility model's microbial sample preservation device are achieved through the following specific technical means:
[0006] A microbial sample preservation device, comprising:
[0007] The sample box is a circular box structure, and rectangular track holes are provided on the left and right sides of the sample box.
[0008] The lifting operation block is a rectangular block structure consisting of two pieces, which are slidably connected in rectangular track holes on the left and right sides of the sample box.
[0009] A lifting linkage shaft, wherein the lifting linkage shaft has a cylindrical structure, and one end of the lifting linkage shaft is fixedly connected to the inner end face of the lifting linkage shaft;
[0010] The sample box cover is a circular plate structure and is movably disposed on the upper surface of the sample box body.
[0011] A lid locking assembly is disposed around the sample box lid;
[0012] The lid lifting assembly consists of two parts, which are located inside the left and right sides of the sample box.
[0013] Furthermore, the lid locking assembly includes:
[0014] Circular stripes, which are composed of a circular array of several rectangular strip-shaped structures, are set on the upper surface of the sample box lid.
[0015] Furthermore, the lid locking assembly also includes:
[0016] The locking blocks are two block-shaped structures, which are fixedly installed at the front and rear ends of the cylindrical surface of the sample box cover.
[0017] The locking block slot is a block-shaped structure with a rectangular slot. There are two locking blocks. The two locking blocks are fixedly installed on the front and rear sides of the upper end of the cylindrical surface of the sample box. The locking blocks and the locking blocks are interlocked.
[0018] Furthermore, the lid locking assembly also includes:
[0019] The rubber seal is a ring-shaped rectangular strip structure made of rubber material, and is fixedly installed on the lower end face of the sample box lid.
[0020] Furthermore, the lid lifting assembly includes:
[0021] The first inclined block is a block structure with an inclined upper surface. The outer end face of the first inclined block is fixedly connected to the inner end of the lifting linkage shaft.
[0022] The second inclined block is a block-shaped structure with an inclined lower end. The upper end of the second inclined block is fixedly connected to the lower end of the sample box lid, and the lower end of the second inclined block is slidably connected to the inclined upper end of the first inclined block.
[0023] Furthermore, the lid lifting assembly also includes:
[0024] A reset compression spring, the outer end of which is fixedly connected to the inner end of the lifting operation block;
[0025] A reset retaining ring, which has a circular plate-like structure, is concentrically slidably connected to the cylindrical surface of the lifting linkage shaft. The inner end face of the reset retaining ring is movably connected to the outer end face of the first inclined block, and the outer end face of the reset retaining ring is fixedly connected to the inner end of the reset compression spring.
[0026] Compared with the prior art, the present invention has the following beneficial effects:
[0027] First, the device provides a reliable mechanical locking mechanism through a lid locking assembly, ensuring a tight connection between the lid and the container body. This design not only prevents sample spillage due to accidental tipping or drops, but also further enhances the seal by incorporating a rubber strip structure at the bottom of the lid, effectively isolating external contaminants and improving insulation, which is particularly important for microbial samples requiring specific temperature environments for preservation.
[0028] Secondly, the device is equipped with a lid-lifting assembly, which solves the problem of difficulty in removing the lid due to atmospheric pressure. Users only need to press the buttons at both ends of the container to balance the atmospheric pressure difference inside and outside the container, thus smoothly lifting the lid without moving the sample container. This design greatly simplifies the user's operation process, reduces potential human error during sample processing, and protects precious microbial samples from damage.
[0029] Then, combining the above two points, this preservation device significantly improves the safety of samples throughout the entire preservation and transportation process. Both the safety locking mechanism achieved through anti-slip stripes and the risk of lid removal avoided by the lid-lifting assembly effectively prevent leakage or damage to microbial samples due to physical causes (such as tipping or falling), ensuring sample integrity and the reliability of experimental results. Furthermore, the excellent sealing performance also helps maintain biosafety and reduce potential biohazards.
[0030] This invention significantly improves the safety, stability, and ease of use for sample preservation. The device employs a lid locking assembly combined with anti-slip strips and rubber strips, achieving excellent sealing to prevent external contamination and enhance insulation performance. It also effectively prevents sample spillage due to tipping or drops. Furthermore, a specially designed lid lifting assembly allows users to easily balance internal and external air pressure by pressing a button, smoothly removing the lid without disturbing the sample, greatly simplifying the operation and protecting sample integrity. In summary, this preservation device provides a high level of safety for microbial samples, ensuring their integrity and reliability during preservation and transportation, while also improving user efficiency.

[0038] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0039] Example 1:
[0040] As attached Figure 1 To be continued Figure 5 As shown:
[0041] This utility model provides a microbial sample preservation device, comprising:
[0042] Sample box 9 is a circular box structure with rectangular track holes on the left and right sides.
[0043] The lifting operation block 10 is a rectangular block structure with two pieces. The two lifting operation blocks 10 are slidably connected in the rectangular track holes opened on the left and right sides of the sample box body 9.
[0044] The lifting linkage shaft 11 has a cylindrical structure, and one end of the lifting linkage shaft 11 is fixedly connected to the inner end face of the lifting linkage shaft 11.
[0045] The sample box cover 12 is a circular plate structure and is movably disposed on the upper end face of the sample box body 9.
[0046] A lid locking assembly is provided around the sample box lid 12;
[0047] The lid lifting assembly consists of two parts, which are located inside the left and right sides of the sample box body 9.
[0048] The lid locking assembly includes:
[0049] The circumferential stripe 1 is composed of a circular array of several rectangular stripe structures. The circumferential stripe 1 is set on the upper surface of the sample box cover 12. In use, the several circumferentially arranged circumferential stripes 1 set on the upper end of the sample box cover 12 can effectively improve the friction of the sample box cover 12 surface and prevent the hand from slipping when twisting the upper surface of the sample box cover 12.
[0050] The lid locking assembly also includes:
[0051] Locking block 2, there are two of them, which are block-shaped structures. The two locking blocks 2 are fixedly installed at the front and rear ends of the cylindrical surface of the sample box cover 12.
[0052] The locking slot 3 consists of two block-shaped structures with rectangular slots. The two locking slot blocks 3 are fixedly installed on the front and rear sides of the upper end of the cylindrical surface of the sample box body 9. The locking block 2 and the locking slot block 3 are interlocked. In use, after the user puts the microbial sample into the sample box body 9, he / she rotates the sample box cover 12 counterclockwise by hand with the help of the friction of the circumferential stripes 1 to lock the sample box cover 12 onto the sample box body 9, preventing the microbial sample from spilling out due to external factors. When it is necessary to take out the microbial sample, the sample box cover 12 should be rotated clockwise to release the locking state between the sample box cover 12 and the sample box body 9.
[0053] The lid locking assembly also includes:
[0054] The rubber seal 4 is a ring-shaped rectangular strip structure made of rubber material. The rubber seal 4 is fixedly installed on the lower end face of the sample box cover 12. During use, the rubber material of the rubber seal 4 can provide a sealing effect between the sample box cover 12 and the sample box body 9, preventing microorganisms in the sample box body 9 from being contaminated. At the same time, since the rubber seal 4 is made of rubber material, it can effectively improve the locking force between the locking block 2 and the locking block groove 3, making the sample box cover 12 more secure.
[0055] The lid lifting assembly includes:
[0056] The first inclined block 5 is a block structure with an inclined upper surface. The outer end face of the first inclined block 5 is fixedly connected to the inner end of the lifting linkage shaft 11.
[0057] The second inclined block 6 is a block structure with a sloping lower end. The upper end of the second inclined block 6 is fixedly connected to the lower end of the sample box cover 12. The lower end of the second inclined block 6 and the upper end of the first inclined block 5 are slidably connected to each other. In use, after the device is unlocked, the user uses two fingers to pinch the left and right parts inward to lift the operating block 10 and drive the first inclined block 5 to move inward. Since the lower end of the second inclined block 6 and the upper end of the first inclined block 5 are slidably connected to each other, the second inclined block 6 drives the sample box cover 12 upward to move away from the sample box body 9. This makes the atmospheric pressure inside the sample box body 9 equal to that of the environment, making it easier for the user to remove the sample box cover 12 for sample extraction and preventing the risk of the sample box body 9 being pulled upward along with the sample box cover 12, causing the sample to spill.
[0058] The lid lifting assembly also includes:
[0059] The outer end of the reset compression spring 7 is fixedly connected to the inner end of the lifting operation block 10.
[0060] The reset retaining ring 8 is a circular plate structure that is concentrically slidably connected to the cylindrical surface of the lifting linkage shaft 11. The inner end face of the reset retaining ring 8 is movably connected to the outer end face of the first inclined block 5, and the outer end face of the reset retaining ring 8 is fixedly connected to the inner end of the reset compression spring 7. In use, because the reset compression spring 7 has a certain elasticity, when two fingers release the lifting operation block 10, the lifting operation block 10 is driven to move backward to reset the first inclined block 5 to the initial position under the elastic action of the reset compression spring 7. This allows the sample box cover 12 to be repositioned on top of the sample box body 9 without protrusion. After being closed, the sample box cover 12 is rotated counterclockwise to lock the sample box cover 12 to the upper end of the sample box body 9.
[0061] The specific usage and function of this first embodiment are as follows:
[0062] During use, the several circumferentially arranged stripes 1 on the upper end of the sample box lid 12 effectively increase the friction of the sample box lid 12 surface, preventing slippage when the user twists the sample box lid 12. After placing the microbial sample into the sample box body 9, the user can use the friction of the circumferential stripes 1 to rotate the sample box lid 12 counterclockwise to lock the sample box lid 12 onto the sample box body 9, preventing the microbial sample from spilling due to external factors. When it is necessary to remove the microbial sample, the user should first rotate the sample box lid 12 clockwise to release the locking state between the sample box lid 12 and the sample box body 9. The rubber material of the rubber seal 4 provides a sealing effect between the sample box lid 12 and the sample box body 9, preventing the microorganisms inside the sample box body 9 from being contaminated. At the same time, because the rubber seal 4 is made of rubber and has a certain degree of elasticity, it can effectively increase the locking force between the locking block 2 and the locking block groove 3, making the sample box lid 12 more secure. After the device is in the unlocked state, use... The user uses two fingers to pinch the left and right operating blocks 10 inwards, causing the first inclined block 5 to move inwards. Since the lower end face of the second inclined block 6 is slidably connected to the upper end face of the first inclined block 5, the second inclined block 6 moves upwards, causing the sample box cover 12 to move upwards away from the sample box body 9. This makes the atmospheric pressure inside the sample box body 9 equal to that of the environment, making it easier for the user to remove the sample box cover 12 for sample extraction. This prevents the sample box body 9 from being pulled upwards along with the sample box cover 12, which could cause the sample to spill. Since the reset compression spring 7 has a certain elasticity, when the two fingers release the operating block 10, the elasticity of the reset compression spring 7 causes the operating block 10 to move outwards, causing the first inclined block 5 to move backwards to return to its initial position. This allows the sample box cover 12 to be placed back on top of the sample box body 9 without protrusion. After it is closed, the sample box cover 12 is rotated counterclockwise to lock it in place at the upper end of the sample box body 9.
