Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a test tube rack storage and retrieval device. Background Technology
[0002] Currently, the telescopic tray method is widely used in the test tube rack storage and retrieval device market. However, this method has several insurmountable drawbacks. First, its complex structural design involves numerous mechanical transmission components, resulting in cumbersome manufacturing processes and high production costs. Second, in practical applications, the telescopic tray requires significant vertical space for storage and retrieval, severely limiting its application in space-constrained environments and imposing stringent height requirements, significantly reducing space utilization. Third, this storage and retrieval method is extremely inefficient, only allowing storage and retrieval of a single test tube rack at a time. In scenarios such as hospital laboratories and research labs where frequent and large-volume processing of test tube racks is required, this inefficient method severely restricts work progress, increases the workload of operators, and is prone to human error due to prolonged repetitive operations. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a test tube rack storage and retrieval device, which has the advantages of simple structure, low failure rate, and the ability to store two or more test tube racks at a time with high efficiency. It solves the problem that most test tube rack storage and retrieval devices on the market use telescopic trays for storage and retrieval, which has the disadvantages of complex structure, occupying a lot of height space, and only being able to store and retrieve one test tube rack at a time, resulting in extremely low efficiency.
[0005] (II) Technical Solution
[0006] To achieve the aforementioned goals of simple structure, low failure rate, and high efficiency in storing two or more test tube racks at once, this utility model provides the following technical solution: a test tube rack storage and retrieval device, comprising a main body, wherein a storage and retrieval device is disposed inside the main body, the storage and retrieval device comprising a linear rail fixedly installed at the bottom of the main body, a pushing device being installed on the outer side of one end of the linear rail, and a rotating device being installed on the other end.
[0007] The rotating device is equipped with a pusher, and the pushing device is used to drive the rotating device to move on the rail, thereby causing the pusher to push the test tube rack placed inside the main body into the shelf.
[0008] The rotating device includes a rotating pull rod, and a lever perpendicular to the rotating pull rod is provided at one end of the rotating pull rod near the pushing device. The rotating device is used to change the vertical and horizontal state of the lever. When the lever is in the horizontal state, the rotating pull rod can pass under the test tube rack. When the lever is in the vertical state, the lever can hook the test tube rack in the shelf and pull the test tube rack out of the shelf.
[0009] Preferably, test tube rack supports are arranged in parallel on the two side walls inside the main body.
[0010] Preferably, a first slider and a second slider are respectively provided at both ends of the linear guide.

[0016] (III) Beneficial Effects
[0017] Compared with the prior art, the present invention provides a test tube rack storage and retrieval device, which has the following beneficial effects:
[0018] This test tube rack storage and retrieval device works by coordinating the main body, the storage and retrieval mechanism, and the shelf. When the test tube rack is to be placed on the shelf, the second motor rotates, the lever of the rotating pull rod of the storage and retrieval mechanism rotates to a horizontal position, then the first motor rotates, and the pusher pushes the test tube rack placed inside the main body into the shelf. After the test tube rack is in the shelf, the first motor rotates in the opposite direction, the rotating pull rod retracts, and the test tube rack is stored.
[0019] When retrieving the test tube rack, the second motor rotates, and the lever of the retrieval device rotates to a horizontal position. Then, the first motor rotates, and the rotating lever extends to the innermost part of the shelf. Then, the second motor rotates in the opposite direction, and the lever of the rotating lever rotates to a vertical position. Then, the first motor rotates in the opposite direction, and the rotating lever retracts. The lever of the rotating lever hooks the innermost test tube rack and pulls the test tube rack on the shelf into the main body, thus completing the retrieval of the test tube rack.
[0020] This achieves the effects of simple structure, low failure rate, and high efficiency in storing two or more test tube racks at a time. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0033] Please see Figure 1-7 A test tube rack storage and retrieval device 2 includes a main body 1, which is the basic structure of the entire device. The main body 1 provides space for the installation and operation of other internal components, and also stores test tube racks that need to be retrieved or stored. The storage and retrieval device 2 is installed inside the main body 1. The device includes a linear guide 21 fixedly installed at the bottom of the main body 1. A pushing device 22 and a rotating device 23 are respectively installed at both ends of the linear guide 21. The linear guide 21, fixedly installed at the bottom of the main body 1, provides a track for the rotating device 23. It ensures that the rotating device 23 moves linearly along a specific path, making the movement of the pusher 28 and the rotating pull rod 235 more stable and precise, thereby improving the accuracy of test tube rack storage and retrieval.
[0034] A pusher 28 is provided on the rotating device 23, and a pushing device 22 is used to drive the rotating device 23 to move on the rail 21, thereby causing the pusher 28 to push the test tube rack placed inside the main body 1. The pushing device 22 is connected to the rotating device 23, and its main function is to provide power for the movement of the rotating device 23. By driving the rotating device 23 to move on the rail 21, the pusher 28 can generate a pushing force, thereby pushing the test tube rack placed inside the main body 1 towards the shelf 3, completing the storage action of the test tube rack.
[0035] The rotating device 23 includes a rotating pull rod 235. A lever 236, perpendicular to the rotating pull rod 235, is located at one end of the rotating pull rod 235 near the pushing device 22. The rotating device 23 is used to change the vertical and horizontal state of the lever 236. When the lever 236 is horizontal, the rotating pull rod 235 can pass under the test tube rack placed inside the main body 1. When the lever 236 is vertical, it can hook onto the test tube rack inside the shelf 3 and pull the test tube rack out of the shelf 3. The change in the state of the lever 236 determines the different functions of the rotating pull rod 235. In the horizontal state, it provides conditions for the rotating pull rod 235 to pass under the test tube rack, facilitating the pusher head 28 to push the test tube rack; in the vertical state, the lever 236 can hook onto the test tube rack, and under the action of the rotating pull rod 235, the test tube rack is removed from the shelf 3.
[0036] The main body 1 has two side walls inside which test tube rack supports 11 are arranged side by side, and the test tube racks are placed on the test tube rack supports 11. The test tube rack supports 11 enable the test tube racks to be placed stably inside the main body 1, preventing the test tube racks from shaking or tipping over during storage. This ensures the stability of the test tube racks when they are waiting to be stored in the shelf 3 or when they are temporarily stored in the main body 1 after being taken out of the shelf 3. It also helps to protect the test tube racks and the test tubes inside, preventing damage caused by instability.
[0037] The two ends of the linear guide 21 are respectively provided with a first slider 24 and a second slider 25. The first slider 24 is used to support the end of the rotating pull rod 235 near the pushing device 22, and the second slider 25 is used to fix the rotating device 23 and allow the rotating device 23 to slide on the linear guide 21.
[0038] The pushing device 22 includes a first motor 221 located below the main body 1 near the lever 236. A first drive wheel 222 located inside the main body 1 is mounted on the motor shaft of the first motor 221. A first synchronous belt 223 is provided on the first drive wheel 222, and a first driven wheel 224 is provided at the other end of the first synchronous belt 223. This is the prior art. The first synchronous belt 223 is driven by the first motor 221 to rotate, which in turn drives the rotating device 23, which is fixedly connected to the first synchronous belt 223, to slide along the linear guide 21, thereby realizing the corresponding actions of the rotating pull rod 235 and the push head 28.
[0039] The bottom of the rotating device 23 is fixedly connected to the second slider 25. The rotating device 23 is also fixedly connected to one end of the first synchronous belt 223 near the first driven wheel 224. The rotating device 23 includes a second motor 231, a second driving wheel 232 is mounted on the motor shaft of the second motor 231, a second synchronous belt 233 is provided on the second driving wheel 232, and a second driven wheel 234 is provided at the other end of the second synchronous belt 233. The above is the prior art. The second driven wheel 234 is driven to rotate by the second motor 231, and the rotation of the second driven wheel 234 drives the rotating pull rod 235 fixedly connected to it to rotate, thereby changing the horizontal and vertical state of the lever 236.
[0040] One end of the rotating pull rod 235 is fixedly connected to the second driven wheel 234. When the second motor 231 drives the second driving wheel 232 to rotate, the second driving wheel 232 drives the second driven wheel 234 to rotate, which in turn drives the rotating pull rod 235 to rotate, thereby changing the horizontal and vertical position of the lever 236.
[0041] A support base 26 is fixedly mounted on the first slider 24, and a linear bearing 27 is installed on the support base 26. The other end of the rotating pull rod 235 passes through the linear bearing 27. The support base 26 is fixedly mounted on the first slider 24, serving to bear and support the linear bearing 27. The linear bearing 27 serves two purposes: firstly, it ensures that the rotating pull rod 235 can move flexibly in the axial direction, enabling the storage and retrieval of the test tube rack; secondly, it guides the rotating pull rod 235, ensuring that it does not deviate radially during movement.
[0042] The shelf 3 has at least three layers of test tube rack trays 31. The shelf 3 is a structure used to store test tube racks, serving to support and fix the test tube rack trays 31, providing a stable storage space for the test tube racks, allowing them to be arranged and stored in an orderly manner, facilitating management and retrieval. Each tray is used to place the test tube rack, providing support and ensuring that the test tube racks can be placed stably, while also facilitating the smooth use of the test tube rack storage and retrieval device 2.
[0043] Working principle: When the test tube rack is to be placed on the shelf 3, the second motor 231 rotates, the lever 236 of the rotating pull rod 235 of the storage and retrieval device 2 rotates to a horizontal state, and then the first motor 221 rotates, and the pusher 28 pushes the test tube rack placed inside the main body 1 into the shelf 3. After the test tube rack enters the shelf 3, the first motor 221 rotates in the opposite direction, the rotating pull rod 235 retracts, and the test tube rack is stored.
[0044] When retrieving the test tube rack, the second motor 231 rotates, and the lever 236 of the rotating pull rod 235 of the storage and retrieval device 2 rotates to a horizontal position. Then, the first motor 221 rotates, and the rotating pull rod 235 extends to the innermost part of the shelf 3. Then, the second motor 231 rotates in the opposite direction, and the lever 236 of the rotating pull rod 235 rotates to a vertical position. Then, the first motor 221 rotates in the opposite direction, and the rotating pull rod 235 retracts. The lever 236 of the rotating pull rod 235 hooks the innermost test tube rack and pulls the test tube rack on the shelf 3 into the main body 1, thus completing the retrieval of the test tube rack.
