Cryopreservation rack placement structure

Abstract

This utility model discloses a cryopreservation rack placement structure, including multiple cryopreservation rack bodies disposed within a liquid nitrogen tank body, and further including: a storage unit, including a sealing component for sealing the upper opening of the liquid nitrogen tank body, and a cryopreservation component disposed inside the sealing component for suspending the cryopreservation rack body; and a positioning unit disposed at the upper end of the sealing component for positioning the cryopreservation component. By opening the sealing component and removing the positioning unit corresponding to the cryopreservation component to be removed, while the remaining positioning units still lock the cryopreservation component, even if the removed cryopreservation rack body rubs against an adjacent cryopreservation rack body when it is lifted out of the liquid nitrogen tank body, the adjacent cryopreservation rack body can still remain stationary under the locking action of the positioning unit, thereby preventing the samples on the adjacent cryopreservation rack bodies from shifting or tipping over.

Description

Technical Field

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

[0002] As the core storage device for biological samples, liquid nitrogen tanks generally use multiple cryopreservation racks placed vertically for storage. The upper end of each cryopreservation rack is hung on the upper opening of the liquid nitrogen tank via a hanging rod, so that the cryopreservation rack can be suspended inside the liquid nitrogen tank.

[0003] However, when placing a certain weight of samples in the cryopreservation rack, the existing technology uses a simple hanging rod to suspend the cryopreservation rack inside the liquid nitrogen tank. Because the cryopreservation rack inside the liquid nitrogen tank lacks a positioning structure and the distance between adjacent cryopreservation racks is small, when one cryopreservation rack is lifted out, the lifted cryopreservation rack may rub against the adjacent cryopreservation rack, causing the adjacent cryopreservation rack to swing. This can cause the samples stored in the cryopreservation rack to shift or even tip over, affecting the quality of sample cryopreservation.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this invention is to provide a cryopreservation rack placement structure to solve the problem mentioned in the background art that the cryopreservation rack in the prior art lacks a positioning structure in the liquid nitrogen tank, which causes the removed cryopreservation rack to rub against the adjacent cryopreservation rack during the process of removing the cryopreservation rack from the liquid nitrogen tank, resulting in the displacement or tipping of the samples in the adjacent cryopreservation rack.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The cryopreservation rack placement structure includes multiple cryopreservation rack bodies housed within the liquid nitrogen tank body, and also includes:

[0008] The storage unit includes a sealing assembly for sealing the upper opening of the liquid nitrogen tank body, and a cryopreservation assembly disposed inside the sealing assembly for suspending the cryopreservation rack body.

[0009] A positioning unit is located at the upper end of the enclosed component and is used to position the cryopreservation component.

[0010] Furthermore, the enclosed component includes:

[0011] A can opening ring is fixedly connected to the upper opening of the liquid nitrogen tank body. The upper end of the can opening ring is provided with grooves at equal angles to limit the position of the cryopreservation components.

[0012] A can lid is placed at the upper end of the can opening ring, and a plug for sealing the can opening ring is fixedly connected to the lower end of the can lid.

[0013] Furthermore, the cryopreservation component includes:

[0014] A hanging rod is hung inside the slot, and a first limiting block is fixedly connected to the lower end of the hanging rod and outside the can opening ring for limiting the hanging rod.

[0015] The lifting rod is fixedly connected to the lower end of the hanging rod and located inside the liquid nitrogen tank body, and is used to suspend the cryopreservation rack body.

[0016] Furthermore, the positioning unit includes:

[0017] A locking block is inserted into the slot, the width of the locking block being adapted to the width of the slot. The upper end of the locking block is at the same level as the upper end of the can opening ring, and is used to cooperate with the can lid to seal the slot. The lower end of the locking block is provided with a notch for accommodating the hanging rod.

[0018] Furthermore, the positioning unit also includes:

[0019] The slide bar is provided in two sets, which are respectively slidably inserted into the upper part of the card block. The card block is provided with a first guide groove for guiding the movement of the slide bar.

[0020] A push block is fixedly connected to the upper end of the corresponding slide rod near the end, and is used to adjust the position of the slide rod. The plane where the upper end of the push block is located is lower than the plane where the upper end of the locking block is located.

[0021] The second limiting block is fixedly connected to the lower end of the slide rod, and the inside of the locking block is provided with a retraction groove for guiding the movement of the second limiting block.

[0022] Furthermore, one end of the bottom of the second limiting block extends from the inside of the locking block to the inside of the can opening ring;

[0023] The can opening ring is provided with a positioning groove inside and outside the second limiting block for positioning the second limiting block.

[0024] Furthermore, the two sets of sliding rods are provided with corresponding second guide grooves inside;

[0025] The second guide groove has a sliding insertion limit plate inside;

[0026] A guide shaft is fixedly connected between the two sets of limiting discs, and the guide shaft is slidably connected to the slide rod;

[0027] A clamping spring is fitted on the outside of the guide shaft and between the two sets of slide rods to clamp the slide rods.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] This invention suspends the cryopreservation rack body inside the liquid nitrogen tank using a cryopreservation component within a sealed assembly. A positioning unit then locks the cryopreservation component to the sealed assembly. When the cryopreservation rack body is removed from the liquid nitrogen tank, the sealed assembly is opened, and the positioning unit corresponding to the desired cryopreservation component is removed, while the remaining positioning units continue to lock the cryopreservation component. This ensures that even if the removed cryopreservation rack body rubs against an adjacent cryopreservation rack body, the adjacent cryopreservation rack body remains stationary due to the locking action of the positioning units, thus preventing sample displacement or tipping on adjacent cryopreservation rack bodies.

Detailed Implementation

[0038] 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.

[0039] Please see Figure 1-7 This utility model provides a technical solution:

[0040] The cryopreservation rack placement structure includes multiple cryopreservation rack bodies 123 disposed within the liquid nitrogen tank body 100, and also includes:

[0041] Storage unit 1 includes a sealing component 11 for sealing the upper opening of the liquid nitrogen tank body 100, and a cryopreservation component 12 disposed inside the sealing component 11 for suspending the cryopreservation rack body 123.

[0042] Positioning unit 2 is located at the upper end of the sealing component 11 and is used to position the cryopreservation component 12.

[0043] It should be noted that: by using a cryopreservation component 12 inside the sealed component 11 to suspend the cryopreservation rack body 123 inside the liquid nitrogen tank body 100, and then locking the cryopreservation component 12 to the sealed component 11 through the positioning unit 2, when the cryopreservation rack body 123 is removed from the liquid nitrogen tank body 100, the sealed component 11 is opened, and the positioning unit 2 corresponding to the cryopreservation component 12 to be removed is taken out, while the remaining positioning units 2 still lock the cryopreservation component 12. This ensures that when the cryopreservation rack body 123 is removed from the liquid nitrogen tank body 100, even if the removed cryopreservation rack body 123 rubs against an adjacent cryopreservation rack body 123, the adjacent cryopreservation rack body 123 can still remain stationary under the locking action of the positioning unit 2, thereby preventing the samples on the adjacent cryopreservation rack body 123 from shifting or tipping over.

[0044] As an improvement, such as Figure 2-4 As shown, the enclosure component 11 includes:

[0045] The can opening ring 111 is fixedly connected to the upper opening of the liquid nitrogen tank body 100. The upper end of the can opening ring 111 is provided with a groove 1111 at an equal angle to limit the position of the cryopreservation component 12.

[0046] A can lid 112 is placed at the upper end of the can opening ring 111, and a plug 113 for sealing the can opening ring 111 is fixedly connected to the lower end of the can lid 112.

[0047] Furthermore, such as Figure 4-5As shown, the cryopreservation component 12 includes:

[0048] The hanging rod 121 is hung inside the slot 1111. A first limiting block 1211 is fixedly connected to the lower end of the hanging rod 121 and outside the can opening ring 111 for limiting the hanging rod 121.

[0049] The lifting rod 122 is fixedly connected to the lower end of the hanging rod 121 and located inside the liquid nitrogen tank body 100, and is used to suspend the cryopreservation rack body 123.

[0050] As an improvement, such as Figure 5-7 As shown, the positioning unit 2 includes:

[0051] A locking block 21 is inserted into the locking slot 1111. The width of the locking block 21 is adapted to the width of the locking slot 1111. The upper end of the locking block 21 is at the same level as the upper end of the can opening ring 111. It is used to cooperate with the can lid 112 to seal the locking slot 1111. The lower end of the locking block 21 is provided with a notch 214 for accommodating the hanging rod 121.

[0052] Furthermore, such as Figure 6-7 As shown, the positioning unit 2 further includes:

[0053] The slide bar 22 is provided in two sets, which are respectively slidably inserted into the upper part of the inner part of the locking block 21. The locking block 21 is provided with a first guide groove 212 for guiding the movement of the slide bar 22.

[0054] Push block 23 is fixedly connected to the upper end of the corresponding slide rod 22 near the end, and is used to adjust the position of the slide rod 22. The plane where the upper end of the push block 23 is located is lower than the plane where the upper end of the locking block 21 is located. The upper end of the locking block 21 is provided with a receiving groove 211 for providing pressing space for the push block 23.

[0055] The second limiting block 24 is fixedly connected to the lower end of the slide rod 22, and the locking block 21 is provided with a retraction groove 213 for guiding the movement of the second limiting block 24.

[0056] Furthermore, one end of the bottom of the second limiting block 24 extends from the inside of the locking block 21 to the inside of the can opening ring 111;

[0057] The can opening ring 111 is provided with a positioning groove 1112 for positioning the second limiting block 24 inside and outside the second limiting block 24.

[0058] The two sets of slide rods 22 are respectively provided with second guide grooves 221 inside;

[0059] The second guide groove 221 is internally connected to a limiting disk 251;

[0060] A guide shaft 25 is fixedly connected between the two sets of limiting discs 251, and the guide shaft 25 is slidably connected to the slide rod 22;

[0061] A tensioning spring 26 is sleeved on the outside of the guide shaft 25 and between the two sets of slide rods 22 for tightening the slide rods 22.

[0062] It should be noted that: in the specific implementation process of this utility model, if... Figure 1-4 As shown, by placing the hanging rod 121 in the slot 1111, the hanging rod 121, through the lifting rod 122, places the cryopreservation rack body 123 containing the sample into the liquid nitrogen tank body 100. Then, the push block 23 is pushed in the opposite direction. The push block 23, through the sliding rod 22, drives the second limiting block 24 to fully enter the slot 21. At this time, the slot 21 is inserted into the slot 1111, so that the notch 214 is fitted on the outside of the hanging rod 121. The push block 23 is released, and the sliding rod 22, under the elastic force of the top spring 26, drives the second limiting block 24 into the positioning groove 1112, completing the locking of the hanging rod 121. Subsequently, the tank cover 112 is placed on the upper end of the tank opening ring 111, so that the plug 113 is inserted into the tank opening. The lower end of the tank cover 112 is sealed with the tank opening ring 111 and the upper end of the slot 21 to prevent the liquid nitrogen in the liquid nitrogen tank body 100 from evaporating.

[0063] like Figure 2-7 As shown, when it is necessary to remove one of the cryogenic rack bodies 123 inside the liquid nitrogen tank body 100, the tank lid 112 is opened, and the push block 23 corresponding to the cryogenic rack body 123 is pressed in the opposite direction simultaneously. The push block 23 drives the slide rod 22 to move in the opposite direction simultaneously. At this time, the clamping spring 26 is gradually compressed, the limiting plate 251 moves along the inside of the second guide groove 221, and the slide rod 22 drives one end of the second limiting block 24 to completely enter the inside of the locking block 21 through the positioning groove 1112. Pull the locking block 21 upward from the slot 1111, and then lift the cryopreservation rack body 123 out of the liquid nitrogen tank body 100 by means of the hanging rod 121 and the lifting rod 122. During this process, the cryopreservation rack body 123 adjacent to the lifted cryopreservation rack body 123 remains stationary under the locking action of the locking block 21, thereby preventing the adjacent cryopreservation rack body 123 from swinging when it is lifted, which would cause the sample to shift or tip over.
