Description

Technical Field

[0001] This utility model relates to the technical field of cryopreservation tube racks, specifically a disc-shaped cryopreservation tube rack. Background Technology

[0002] Cryopreservation tube racks are commonly used sample storage aids in biological and medical laboratories. They are mainly used to neatly place cryopreservation tubes (containing biological samples such as cells, bacteria, and tissues) to prevent samples from being disordered or tipped over. Their structure needs to be adapted to the size of cryopreservation tubes of different specifications. The materials are mostly low-temperature resistant and easy-to-clean plastics or metals. Some racks need to have a certain load-bearing capacity and stability to ensure safe use in scenarios such as refrigerator refrigeration and liquid nitrogen freezing. They are key laboratory equipment to ensure the orderly storage and convenient retrieval of samples.

[0003] Existing cryopreservation tube racks have obvious drawbacks in terms of storage and retrieval efficiency and ease of operation: most traditional racks use a fixed hole array structure, and cryopreservation tubes need to be inserted or pulled out of the holes one by one. When multiple cryopreservation tubes need to be retrieved in batches, they need to be operated one by one, which is time-consuming and laborious. Utility Model Content

[0004] The purpose of this invention is to provide a disc-shaped cryopreservation tube holder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a disc-shaped cryopreservation tube holder, including a base, a placement mechanism on the top of the base, and a positioning mechanism on the front side of the placement mechanism.

[0006] The placement mechanism includes a support component, a clamping component, a pulling component, and a connecting component. The support component is located on the top of the base, the clamping component is located on the left and right sides of the support component, the pulling component is located on the outside of the clamping component, and the connecting component is located on the rear side of the support component.

[0007] The positioning mechanism includes a positioning component and a disassembly component. The positioning component is located on the front side of the clamping component, and the disassembly component is located inside the top of the positioning component.

[0008] Preferably, the support assembly includes a platform, which is disposed above the base, and a support rod is fixedly connected to the bottom of the platform and the support rod is fixedly connected to the top of the base.

[0009] Preferably, the clamping assembly includes a clamping edge, which is disposed on the left and right sides of the frame. The inner side of the clamping edge is in contact with the left and right sides of the frame. A first splicing ring is fixedly connected to the inner side of the clamping edge. A second splicing ring is disposed on the inner side of the first splicing ring. The second splicing ring is fixedly connected to the inner ring of the frame. A clamping block is fixedly connected to the inner side of the clamping edge at a position between the first splicing rings. The clamping block is engaged with the inner ring of the frame.

[0010] Preferably, the pulling assembly includes a fixing rod, which is fixedly connected to the outer side of the locking edge, and a handle is fixedly connected to the outer side of the fixing rod.

[0011] Preferably, the connecting assembly includes a fixing plate, which is fixedly connected to the rear side of the frame. A fixing strip is fixedly connected to the inner rear side of the fixing plate. Fixing shafts are fixedly connected to the left and right sides of the fixing strip. A rotating cylinder is rotatably connected to the outer ring of the fixing shaft. The rotating cylinder is fixedly connected to the inner rear side of the retaining edge.

[0012] Preferably, the positioning component includes a retainer, which is fixedly connected to the top front side of the right retainer edge and engages with the top of the left retainer edge. A fixing cylinder is fixedly connected to the top of the retainer, and a sliding piece is slidably connected inside the fixing cylinder. A compression spring is fixedly connected to the top of the sliding piece, and a retaining rod is fixedly connected to the bottom of the sliding piece. The retaining rod engages with the front side of the left and right retainer edges.

[0013] Preferably, the disassembly assembly includes a telescopic slide rod, which is fixedly connected to the top of the slide plate and slidably connected to the top of the fixed cylinder. A pull rod is fixedly connected to the top of the telescopic slide rod.

[0014] Compared with the prior art, the present invention provides a disc-shaped cryopreservation tube holder, which has the following advantages: 1. This disc-shaped cryopreservation tube rack, through its placement mechanism, allows staff to unload multiple cryopreservation tubes on both sides of the rack by flipping the locking edges on the left and right sides. At the same time, staff can also move a single cryopreservation tube upwards for individual storage and retrieval, making it convenient for staff to use.

[0015] 2. This disc-shaped cryopreservation tube holder, through its positioning mechanism, allows the sliding plate to engage with the locking rods on the left and right sides of the stand after the locking edges are aligned with the sides of the stand. This locking mechanism, activated by the compression spring, locks the locking edges in place, increasing the stability of the mounting. Furthermore, the operator can easily release the locking rods from the locking edges by pulling the lever upwards, facilitating opening and closing of the locking edges. The device is simple to operate and convenient for operators.

[0016] 3. The opening and closing of the locking edge of this disc-shaped cryovial holder is for use when disassembling multiple cryovials. Multiple cryovials can be disassembled in a single operation without the need for staff to manually pick them up one by one, but it does not affect the normal retrieval and placement of a single cryovial. In contrast, existing one-piece molded shelves can only achieve a similar effect by flipping the shelf over, causing the cryovials to fall downwards under gravity. However, this operation causes the reagent solution inside the test tube to be flipped over and then fall, resulting in greater shaking of the solution and potentially damaging the stability of the reagent inside the test tube. Furthermore, this shelf can control the test tubes on one side to fall uniformly during use. When collecting test tubes, the cryopreservation tubes can be placed on the left and right sides as needed. After collection, the edges of the different categories can be opened and closed for unified collection, eliminating the need for individual identification later. The operation is simple.

[0021] This utility model provides a technical solution: Example 1

[0022] Combination Figures 1 to 5 A disc-shaped cryopreservation tube holder includes a base 3, a placement mechanism 1 is provided on the top of the base 3, and a positioning mechanism 2 is provided on the front side of the placement mechanism 1.

[0023] The placement mechanism 1 includes a support component 11, a clamping component 12, a pulling component 13, and a connecting component 14. The support component 11 is located on the top of the base 3, the clamping component 12 is located on the left and right sides of the support component 11, the pulling component 13 is located on the outside of the clamping component 12, and the connecting component 14 is located on the rear side of the support component 11.

[0024] Support assembly 11 includes a platform 1101, which is positioned above the base 3. A support rod 1102 is fixedly connected to the bottom of the platform 1101 and to the top of the base 3. Clamping assembly 12 includes a retaining edge 1201, which is located on the left and right sides of the platform 1101. The inner side of the retaining edge 1201 is in contact with the left and right sides of the platform 1101. A first splicing ring 1202 is fixedly connected to the inner side of the retaining edge 1201. A second splicing ring 1203 is located inside the first splicing ring 1202 and is fixedly connected to the outer ring of the platform 1101. The inner side of the retaining edge 1201 is fixedly positioned between the first splicing ring 1202. A locking block 1204 is connected and locked inside the outer ring of the frame 1101. The pulling component 13 includes a fixing rod 1301, which is fixedly connected to the outside of the locking edge 1201. A handle 1302 is fixedly connected to the outside of the fixing rod 1301. The connecting component 14 includes a fixing plate 1401, which is fixedly connected to the rear side of the frame 1101. A fixing strip 1402 is fixedly connected to the inner rear side of the fixing plate 1401. Fixing shafts 1403 are fixedly connected to the left and right sides of the fixing strip 1402. A rotating cylinder 1404 is rotatably connected to the outer ring of the fixing shaft 1403. The rotating cylinder 1404 is fixedly connected to the inner rear side of the locking edge 1201.

[0025] Furthermore, compared to traditional cryopreservation tube racks, the tray-shaped rack in this design allows staff to unload multiple cryopreservation tubes on both sides of the rack 1101 by flipping the locking edges 1201 on the left and right sides. At the same time, staff can also move a single cryopreservation tube upwards for individual storage and retrieval, making it convenient for staff to use.

[0026] Example 2 See Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 Furthermore, based on Embodiment 1, the positioning mechanism 2 includes a positioning component 21 and a disassembly component 22. The positioning component 21 is disposed on the front side of the clamping component 12, and the disassembly component 22 is disposed inside the top of the positioning component 21.

[0027] The positioning component 21 includes a card holder 2101, which is fixedly connected to the top front side of the right card edge 1201 and engages with the top of the left card edge 1201. A fixing cylinder 2102 is fixedly connected to the top of the card holder 2101, and a sliding piece 2103 is slidably connected inside the fixing cylinder 2102. A compression spring 2104 is fixedly connected to the top of the sliding piece 2103, and a locking rod 2105 is fixedly connected to the bottom of the sliding piece 2103. The locking rod 2105 engages with the front side of the left and right card edges 1201. The disassembly component 22 includes a telescopic slide rod 2201, which is fixedly connected to the top of the sliding piece 2103 and slidably connected to the top of the fixing cylinder 2102. A pull rod 2202 is fixedly connected to the top of the telescopic slide rod 2201.

[0028] Furthermore: After the left and right side locking edges 1201 are in contact with the sides of the frame 1101, the slide plate 2103, under the action of the compression spring 2104, drives the locking rod 2105 downward to engage with the front side of the left and right side locking edges 1201, thus locking the position of the two side locking edges 1201. This increases the stability of the two side locking edges 1201 after they are engaged with the frame 1101. At the same time, the operator only needs to pull the lever 2202 upward to release the connection between the locking rod 2105 and the two side locking edges 1201, making it easy for the operator to open and close the locking edges 1201. The operation is simple and convenient for the operator to use.

[0029] In actual operation, when this device is used and it is necessary to open or close the two side retaining edges 1201, the operator first pulls the pull rod 2202 upward. The upward movement of the pull rod 2202 drives the retaining rod 2105 upward through the telescopic slide rod 2201 and the slide plate 2103. The retaining rod 2105 moves upward and retracts into the fixed cylinder 2102, releasing its contact with the two side retaining edges 1201. Then the operator can pull the handles 1302 on both sides outward at the same time. The outward movement of the handles 1302 drives the two side retaining edges 1201 to rotate outward around the fixed shaft 1403. At this time, the two side retaining edges 1201 are opened and closed. At this time, the cryopreservation tube fixed by the two side connecting rings 1202 and 1203 can be disassembled at the same time. When the locking edges 1201 on both sides are closed, the inner and outer rings 1202 and 1203 are spliced ​​together, and the cryopreservation tube is locked in the inner ring of the ring structure formed by splicing ring 1202 and 1203. After the locking edges 1201 are opened and closed, the cryopreservation tube on that side falls off and completes the unified disassembly.
