Description

Technical Field

[0001] This utility model relates to the field of biological experimental technology, specifically a biological sample storage rack. Background Technology

[0002] In the field of biotechnology, the collection, storage and analysis of biological samples are key steps in scientific research, medical diagnosis and new drug development. Among them, test tubes are the most commonly used containers for holding various biological samples such as blood, tissue fluid and cell culture. Their safe and orderly storage and management are of paramount importance.

[0003] Currently, most common test tube storage devices use open shelves or simple fixed bases. While these are convenient for retrieval, they lack effective airtight protection, and samples exposed to air for extended periods are at risk of contamination. Some storage boxes with lids provide protection when closed, but when retrieving samples, users often need to fully open the lid and set it aside before manually extracting or placing the sample from the box into the storage rack. This process is relatively cumbersome, especially in scenarios where multiple test tubes need to be retrieved consecutively. The storage rack cannot be stably positioned for easy operation, requiring users to hold the rack with one hand and operate with the other, which is extremely inconvenient. Therefore, we propose a biological sample storage rack. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a biological sample storage rack. The technical solution adopted is as follows: it includes a box body and a box cover. The box cover is hinged to the top rear side of the box body. The storage rack is slidably installed inside the box body. The storage rack has a rectangular frame structure. Test tube insertion holes are arranged in an evenly spaced array on the top of the storage rack. The left and right sides of the storage rack are connected to the box cover through a connecting unit. The connecting unit includes a connecting rod, a T-shaped slider, a first fixed shaft, a T-shaped groove, and a second fixed shaft. There are two T-shaped grooves. The T-shaped grooves are symmetrically arranged on the left and right sides of the storage rack. T-shaped sliders are slidably installed inside the T-shaped grooves. The first fixed shaft is arranged on the outer middle of the T-shaped slider. The connecting rod is rotatably installed on the outer side of the first fixed shaft. The other end of the connecting rod is rotatably connected to the second fixed shaft arranged on the middle of the left and right ends of the inner side of the box cover. The front side of the box body is provided with a blocking bolt for blocking the storage rack.

[0005] As a preferred technical solution of this utility model, the inner front and rear sides of the box are symmetrically provided with guide rails, and the guide rails are slidably connected to the guide blocks provided at the bottom of the left and right ends of the storage rack.

[0006] As a preferred embodiment of this utility model, two blocking bolts are provided. The blocking bolts are respectively threaded into the screw holes provided on the front side of the box body. The rear ends of the blocking bolts pass through the through holes provided on the guide rails on the front side of the box body, and the rear ends of the blocking bolts extend out of the rear surface of the guide rails on the front side of the box body.

[0007] As a preferred technical solution of this utility model, the inner bottom of the storage rack is provided with tube bottom sockets arranged in an equidistant array, and the tube bottom sockets are respectively arranged directly below the test tube insertion holes, and the middle of the tube bottom socket is provided with an arc-shaped insertion hole.

[0008] As a preferred embodiment of this utility model, at least four elastic clips are arranged in a circular array at equal intervals at the bottom of the test tube insertion hole, and the elastic clips are made of rubber.

[0009] As a preferred technical solution of this utility model, it also includes observation windows. There are two observation windows, which are symmetrically arranged in the middle of the front and rear sides of the box body.

[0010] The beneficial effects of this utility model are as follows: Through the linkage design of the lid and the storage rack, the storage rack automatically rises from the box when the lid is opened, facilitating user access to test tubes and making operation convenient. After retrieval, closing the lid retracts the storage rack back into the box, effectively isolating the sample from the external environment and preventing contamination of biological samples. Furthermore, when multiple test tubes need to be retrieved and placed continuously, the extended storage rack can be supported and fixed by tightening the blocking bolts, ensuring stability. In addition, the cooperation of the guide rail and guide block ensures smooth lifting of the storage rack, and the tube bottom socket and elastic clip work together to provide multi-point support for the test tubes.

[0016] Example 1

[0017] like Figures 1 to 4As shown, this utility model discloses a biological sample storage rack. The technical solution includes a box body 1 and a lid 2. The lid 2 is hinged to the top rear side of the box body 1. A storage rack 3 is slidably installed inside the box body 1. Guide rails 4 are symmetrically arranged on the front and rear sides of the box body 1, and these guide rails 4 are slidably connected to guide blocks at the bottom left and right ends of the storage rack 3. The guide rails 4 inside the box body 1 slide in cooperation with the guide blocks on the storage rack 3, thereby ensuring the stability of the storage rack 3 during movement. The storage rack 3 has a rectangular frame structure. Test tube insertion holes 7 are evenly arranged in an array on the top of the storage rack 3, and tube bottom sockets 8 are evenly arranged in an array on the bottom inner side of the storage rack 3. The tube bottom sockets 8 are respectively positioned directly below the test tube insertion holes 7. The center of the base 8 has an arc-shaped insertion hole, allowing users to place or remove test tubes through the test tube insertion hole 7 at the top of the storage rack 3. The bottom of the test tube is inserted into the arc-shaped insertion hole of the tube bottom socket 8 for support. At least four elastic clips 9, made of rubber, are arranged in a circular array at equal intervals at the bottom of the test tube insertion hole 7 to clamp the test tube and prevent it from shaking. The left and right sides of the storage rack 3 are connected to the box cover 2 through a connecting unit 5. The connecting unit 5 includes a connecting rod 51, a T-shaped slider 52, a first fixed shaft 53, a T-shaped slide groove 54, and a second fixed shaft 55. There are two T-shaped slide grooves 54, which are symmetrically arranged in the middle of the left and right sides of the storage rack 3. The interior of the T-shaped slide groove 54 is slidably installed with... T-shaped slider 52, with a first fixed shaft 53 respectively provided on the middle of the outer side of the T-shaped slider 52. A connecting rod 51 is rotatably mounted on the outer side of the first fixed shaft 53. The other end of the connecting rod 51 is rotatably connected to the second fixed shaft 55 provided on the middle of the left and right ends of the inner side of the cover 2. When the cover 2 is opened, as the cover 2 moves, the second fixed shaft 55 drives the first fixed shaft 53 through the connecting rod 51, causing the T-shaped slider 52 to slide upward in the T-shaped grooves 54 on both sides of the storage rack 3, thereby causing the storage rack 3 to extend upward from the inside of the box body 1. There are two blocking bolts 6 provided on the front side of the box body 1 to block the storage rack 3. The blocking bolts 6 are threaded into the screw holes provided on the front side of the box body 1, and the rear ends of the blocking bolts 6 pass through the screw holes provided on the front side of the box body 1. The storage rack 3 extending out of the box 1 has a through hole on the guide rail 4 on the front side inside the box 1, and the rear end of the blocking bolt 6 extends out of the rear surface of the guide rail 4 on the front side inside the box 1. When fixing the storage rack 3 extending out of the box 1, the blocking bolt 6 can be threaded into the screw hole on the front side of the box 1, so that the rear end of the blocking bolt 6 extends out of the through hole on the guide rail 4 on the front side inside the box 1, thereby blocking the bottom of the storage rack 3 and supporting the storage rack 3. It also includes an observation window 10. There are two observation windows 10, which are symmetrically arranged in the middle of the front and rear sides of the box 1. During the storage and retrieval of test tubes, the user can observe the internal sample condition through the observation windows 10 on the front and rear sides of the box 1 without having to fully open the box cover 2, which is convenient and quick to check.

[0018] The working principle of this utility model is as follows: When a user needs to store or retrieve biological sample tubes, the lid 2 is opened. The lid 2 rotates to the rear of the box body 1 via a hinge. Since the lid 2 is connected to the storage rack 3 via the connecting unit 5, the opening action of the lid 2 will drive the connecting unit 5. As the lid 2 moves, the second fixed shaft 55 drives the first fixed shaft 53 via the connecting rod 51, causing the T-shaped slider 52 to slide upward within the T-shaped grooves 54 on both sides of the storage rack 3, thereby causing the storage rack 3 to extend upward from inside the box body 1. During the extension of the storage rack 3, the guide rail 4 inside the box body 1 slides and engages with the guide block on the storage rack 3, thereby ensuring the storage... The stability of the rack 3 during movement; after the rack 3 extends out of the box 1, the user can place or remove test tubes through the test tube insertion hole 7 at the top of the rack 3. The bottom of the test tube will be inserted into the arc-shaped insertion hole of the tube bottom socket 8 for support. At the same time, the elastic clip 9 at the bottom of the test tube insertion hole 7 will clamp the test tube to prevent it from shaking. When fixing the rack 3 that extends out of the box 1, the blocking bolt 6 can be threaded into the screw hole on the front side of the box 1, so that the rear end of the blocking bolt 6 extends out of the through hole on the guide rail 4 on the front side inside the box 1, thereby blocking the bottom of the rack 3 and supporting the rack 3.
