Description

Technical Field

[0001] This utility model belongs to the field of microbial inoculation technology, specifically relating to a placement rack for microbial inoculation tools. Background Technology

[0002] Microbial inoculation tools are specialized instruments used to transfer target microorganisms to culture media. These tools must be used under aseptic conditions and sterilized. They mainly include metal tools such as inoculation needles, inoculation loops, and inoculation hooks, as well as auxiliary tools such as glass spreaders. Inoculation loops and needles are the most commonly used types in laboratories; the former is often used for streak inoculation, while the latter is suitable for puncture inoculation. Microbial inoculation requires inoculation loops, needles, spreaders, and laboratory punches.

[0003] Currently, in specific experimental operations, using a single inoculation tool is inefficient, and multiple tools are generally used for inoculation. However, when inoculation tools are changed or temporarily not needed, there is nowhere to put them, making them susceptible to contamination and greatly increasing the probability of inoculation contamination. Therefore, we propose a storage rack for microbial inoculation tools. Utility Model Content

[0004] The purpose of this invention is to provide a storage rack for microbial inoculation tools to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a microbial inoculation tool rack, comprising a storage box, a connecting plate, and a rack. The rack is slidably disposed inside the storage box. A transparent cylinder is disposed in the middle of the rack. The connecting plate is fixedly connected to one side of the rack. A storage groove is formed at the top of the connecting plate. A liftable pull plate is slidably disposed inside the storage groove. A shrinkage groove is formed at the top center of the pull plate. A locking block is slidably disposed inside the shrinkage groove. A locking spring is disposed at the bottom of the locking block. A locking slot is formed at the middle of the top of the storage box near the connecting plate. A top plate is disposed on the side of the rack away from the connecting plate. A push-out spring is disposed on the side of the top plate away from the rack. The two ends of the push-out spring are fixedly connected to the inner wall of the storage box and one side of the top plate, respectively.

[0006] Preferably, a pressure block is slidably provided at the top of the storage box corresponding to the card slot, and a top block is provided at the bottom of the pressure block, the top block extending to the inner top of the card slot and slidably connected thereto.

[0007] Preferably, the inner walls on both sides of the storage box are provided with second limiting grooves at the middle and bottom, and the top and bottom of both sides of the top plate are provided with second limiting blocks. The second limiting blocks extend into the interior of the second limiting grooves and are slidably connected to their inner walls.

[0008] Preferably, a limiting protrusion is provided on the outer periphery of the connection between the pressure block and the top block, and a return spring is provided at the bottom of the limiting protrusion.

[0009] Preferably, the shrink groove has a first limiting groove on both sides inside, the card block has a first limiting block on both sides at the bottom end, the first limiting block extends into the interior of the first limiting groove and slides in connection with its inner wall, the storage groove also has a first limiting groove on both sides inside, and the pull plate also has a first limiting block on both sides at the bottom end.

[0010] Preferably, a rubber sleeve is provided on the outer periphery of the connecting plate, and the rubber sleeve is fitted onto the outer periphery of the connecting plate by adhesive bonding.

[0011] Preferably, a lever plate is installed on one side of the top of the pull plate, and the lever plate is fixedly installed on the top of the outer side of the pull plate. Retractable steel columns are provided at the top and bottom of both sides of the pull plate. The steel columns are slidably connected to the pull plate. The end of the steel column is an arc-shaped structure. A spring is provided at one end of the steel column that extends into the pull plate. Resistance grooves are provided at the top of both sides of the connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting up a storage rack with a connecting plate and a top plate inside the storage box, and using the transparent tube on the storage rack to store the inoculation tools, and using a locking block and a locking slot to lock the connecting plate, while using a second limiting block and a second limiting slot to limit the connecting plate and the storage rack, the storage rack is prevented from completely detaching from the storage box. This achieves the storage of the inoculation tools, allowing them to be used alternately during the inoculation process, and avoiding prolonged exposure of the inoculation tools to the outside environment, which could lead to contamination.

[0014] 2. By opening resistance grooves on both sides of the top of the connecting plate, and setting steel columns with springs on both sides of the top and bottom of the pull plate, and making the ends of the steel columns have an arc-shaped convex structure, the ends of the steel columns can form resistance when inserted into the resistance grooves, thereby preventing the pull plate from falling naturally and ensuring the stability of the pull plate after it is stretched upward.

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 Figure 1-4 This utility model provides a technical solution for a microbial inoculation tool placement rack: it includes a storage box 1, a connecting plate 2, and a placement rack 9. The placement rack 9 is slidably arranged inside the storage box 1. A transparent tube 10 is arranged in the middle of the placement rack 9. The connecting plate 2 is fixedly connected to one side of the placement rack 9. A storage groove 20 is opened at the top of the connecting plate 2. A liftable pull plate 21 is slidably arranged inside the storage groove 20. A shrink groove 7 is opened at the center of the top of the pull plate 21. A locking block 4 is slidably arranged inside the shrink groove 7. A locking spring 6 is arranged at the bottom of the locking block 4. A locking groove 15 is opened at the middle of the top of the storage box 1 near the connecting plate 2. A top plate 11 is arranged on the side of the placement rack 9 away from the connecting plate 2. A push-out spring 14 is arranged on the side of the top plate 11 away from the placement rack 9. The two ends of the push-out spring 14 are fixedly connected to the inner wall of the storage box 1 and one side of the top plate 11, respectively.

[0022] Specifically, a pressure block 16 is slidably provided on the top of the storage box 1 at a position corresponding to the card slot 15, and a top block 17 is provided at the bottom of the pressure block 16. The top block 17 extends to the inner top of the card slot 15 and is slidably connected thereto.

[0023] Specifically, the inner walls on both sides of the storage box 1 are provided with second limiting grooves 13 in the middle and bottom, and the top and bottom of both sides of the top plate 11 are provided with second limiting blocks 12. The second limiting blocks 12 extend into the interior of the second limiting grooves 13 and slide in connection with their inner walls.

[0024] Specifically, a limiting protrusion 18 is provided on the outer periphery of the connection between the pressure block 16 and the top block 17, and a reset spring 19 is provided at the bottom of the limiting protrusion 18.

[0025] Specifically, the shrinkage groove 7 has a first limiting groove 8 on both sides inside, the card block 4 has a first limiting block 5 on both sides at the bottom end, the first limiting block 5 extends into the interior of the first limiting groove 8 and slides in connection with its inner wall, the storage groove 20 also has a first limiting groove 8 on both sides inside, and the pull plate 21 also has a first limiting block 5 on both sides at the bottom end.

[0026] Specifically, a rubber sleeve 3 is provided on the outer periphery of the connecting plate 2, and the rubber sleeve 3 is fitted onto the outer periphery of the connecting plate 2 by adhesive bonding.

[0027] Specifically, a lever plate 22 is installed on one side of the top of the pull plate 21. The lever plate 22 is fixedly installed on the top of the outer side of the pull plate 21. Retractable steel columns 23 are provided on both the top and bottom sides of the pull plate 21. The steel columns 23 are slidably connected to the pull plate 21. The end of the steel column 23 is an arc-shaped structure. A spring is provided at one end of the steel column 23 that extends into the pull plate 21. Resistance grooves 24 are provided on both the top and bottom sides of the connecting plate 2.

[0028] In this embodiment, during the microbial inoculation process, when it is necessary to replace or place the inoculation tool, the pull plate 22 can be pulled down to move the pull plate 21 downward, thereby exposing the interior of the storage box 1 for easy access to the inoculation tool. After the tool is accessed, the pull plate 22 can be lifted up to move the pull plate 21 upward, causing the steel columns 23 on both sides of the bottom of the pull plate 21 to extend into the resistance groove 24 under the action of the spring, thereby limiting the pull plate 21. At the same time, the locking block 4 engages with the locking groove 15 to prevent the connecting plate 2 and the pull plate 21 from being pushed out by the ejection spring 14, which would directly expose the inoculation tool and cause contamination. When multiple inoculation tools need to be accessed and placed at the same time, to improve convenience, the pressing block 16 can be pressed to move the top block 17 downward and compress the reset spring. 19. Using the top block 17, the card block 4 inserted into the card slot 15 is pushed out of the card slot 15, causing it to retract into the shrinkage groove 7, thereby achieving the purpose of releasing the locking state. Then, under the action of the push-out spring 14, the top plate 11 is pushed to extend the placement rack 9 and the connecting plate 2 to the outside of the storage box 1, so that the inoculation tools that are not needed for the time being can be placed in the transparent tube 10 in the placement rack 9, and the corresponding inoculation tools can be taken out from the corresponding transparent tube 10 for use. Then, the connecting plate 2 is pushed to move into the storage box 1, so that the second limiting blocks 12 at both ends of the top plate 11 slide along the second limiting groove 13 and compress the push-out spring 14 until the card block 4 moves to the position of the card slot 15, and under the action of the locking spring 6, the card block 4 is pushed into the card slot 15 to achieve the purpose of locking and positioning.
