Description

Technical Field

[0001] This utility model relates to the field of cryopreservation devices, and in particular to a cryopreservation rack. Background Technology

[0002] In the fields of biology and medicine, cryopreservation racks are key storage devices widely used for the cryopreservation of reagents and biological samples. They are typically used in conjunction with cryovials and placed in ultra-low temperature freezers or liquid nitrogen containers. This not only facilitates the management of reagents and samples but also allows for convenient access to and from cryovials in low-temperature environments.

[0003] In related technologies, the cryopreservation rack includes a frame formed by a top plate, a bottom plate, a left side plate, a right side plate, and a rear side plate, and several partitions disposed within the frame and arranged parallel to the top and bottom plates. The partitions divide the frame into multiple storage units, allowing one cryopreservation rack to store multiple cryopreservation boxes simultaneously. The multiple storage units have access ports for easy placement and removal of cryopreservation boxes. However, this structural design has a flaw: cryopreservation boxes within the cryopreservation rack are prone to slipping off their storage openings during transport. This not only causes operational inconvenience but also poses a serious safety threat to the reagents and biological samples stored within. Utility Model Content

[0004] The purpose of this invention is to provide an improved cryopreservation rack, which aims to effectively solve the problem of cryopreservation boxes slipping during transportation.

[0005] The technical solution of this utility model is as follows:

[0006] This utility model discloses a cryopreservation rack, comprising a frame and several compartments, with cryopreservation boxes installed within the compartments. The frame is provided with partitions, each partition having a slot. Each compartment has a handle, and each handle has an elastic buckle. The elastic buckle can be detachably engaged with the slot. The handle and the elastic buckle are designed to be integrally formed. When the handle is in contact with the compartment, the elastic buckle can be engaged within the slot, thus providing a supporting force to prevent the compartments from moving during the handling of the cryopreservation rack, thereby preventing the cryopreservation boxes from slipping.

[0007] Furthermore, to facilitate the retrieval of cryopreservation boxes placed within the compartments, each compartment includes a front panel, a back panel, a bottom panel, and two side panels. The side panels have wavy edges, and the bottom panel has several perforated holes. A cryopreservation box is placed in a corresponding arc shape and perforation hole position. When removing a cryopreservation box, it can be lifted from the bottom of the compartment, and then gripping positions are provided on both sides of the arc shape for quick removal of the cryopreservation box.

[0008] Furthermore, to reduce shaking of the cryopreservation box during handling or to prevent the buckles from dislodging from the slots during handling, the design also includes a secondary fixing component. The secondary fixing component includes a locking strap seat, a locking strap, a male seat, and a female seat. The locking strap seat is located at one end of the locking strap, and the male seat is located at the other end of the locking strap. The locking strap seat is fixedly located at the bottom of the frame, and the female seat is located at the top of the frame. The male seat can be detachably fastened to the female seat. When all the elastic buckles are engaged with the slots, the male seat is fastened into the female seat, and the locking strap blocks all the compartments, forming double protection and effectively preventing the cryopreservation box from sliding out.

[0009] Furthermore, the inner wall of the frame is provided with a sliding groove, and the sides of the double side plates are provided with sliding rails. The sliding rails are located in the sliding grooves. The sliding grooves and sliding rails are designed to cooperate with each other. Antifreeze lubricant can be applied between the sliding grooves and sliding rails to prevent the compartments from becoming unusable due to frost.

[0010] Furthermore, the panel is equipped with label slots, which can be marked on the corresponding compartments to facilitate the search process and make it easier to find the corresponding cryopreservation box.

[0011] Furthermore, the top of the frame is provided with a handle, which facilitates the removal of the cryopreservation rack by a robotic arm during automated storage.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: a handle with an elastic buckle is designed, and the partition is provided with a slot. As the shelves are completely stored in the frame, the handle is laid flat downwards, and the elastic buckle is locked in the slot, thereby fixing the shelves and effectively preventing the shelves from slipping during the handling of the freezer rack.

[0021] Please refer to Figures 1-7 This utility model provides a cryopreservation rack, including a frame 1 and eight compartments 4. Cryopreservation boxes are installed in the compartments 4. The frame 1 is provided with partitions 2, which consist of seven pieces. Each partition 2 has a slot 3. Each compartment 4 is provided with a handle 5, which is used to pull the compartment 4. The handle 5 is provided with an elastic buckle 6, which is made of flexible material. During the pulling process, the elastic buckle 6 can deform. The elastic buckle 6 can be detachably fastened to the slot 3. The handle 5 and the elastic buckle 6 are designed to be integrally formed. When the handle 5 is close to the compartment 4, that is, when the compartment 4 is completely stored in the frame 1, the handle 5 is laid flat downwards, and the elastic buckle 6 can be locked in the slot 3. When the cryopreservation rack is moved, this structure can generate a supporting force, effectively preventing the compartment 4 from shifting and slipping.

[0022] The design of 8 compartments is designed to address the issue that existing cryogenic racks are based on traditional cryogenic boxes, whose dimensions are larger than the diameter of the new cryogenic box. Traditional cryogenic racks only have 5 layers, i.e. 5 compartments. By designing 8 compartments, the space utilization rate of ultra-low temperature freezers can be effectively improved.

[0023] In the actual product, in the side view of the cryopreservation compartment, you can see that the handle 5 protrudes from the surface of the cryopreservation rack. The design of the elastic buckle 6 and the handle 5 as one piece makes the gap between the handle 5 and the panel 41 of the compartment 4 larger, so that the handle 5 can be lifted out through the gap.

[0024] In addition, with the increase in the number of times it is used, frost is easily formed on the surface of the cryopreservation rack. Teflon can be sprayed on the frame 1 and the compartment 4 first, and then a superhydrophobic coating containing nanoparticles (such as silicon dioxide) can be superimposed to improve the anti-icing performance, reduce the thickness of frost, and defrost more quickly.

[0025] To facilitate the easy access to and from the cryopreservation boxes placed in the compartment 4, the compartment 4 includes a front panel 41, a back panel 42, a bottom panel 43, and two side panels 44. The two side panels 44 are provided with wavy edges 441, and the bottom panel 43 is provided with several perforated holes 431. A cryopreservation box is placed at the position of an arc shape and a perforated hole 431. When taking out the cryopreservation box, it can be lifted from the bottom of the compartment 4, and then the two arcs on both sides also leave gripping positions to facilitate the quick removal of the cryopreservation box.

[0026] To reduce shaking of the cryopreservation box during handling or to prevent the buckles from disengaging from the slots 3 during handling, the design also includes a secondary fixing component 7. The secondary fixing component 7 includes a locking strap seat 71, a locking strap 72, a male seat 73, and a female seat 74. The locking strap seat 71 is located at one end of the locking strap 72, and the male seat 73 is located at the other end of the locking strap 72. The locking strap seat 71 is fixed to the bottom of the frame 1, and the female seat 74 is located at the top of the frame 1. The male seat 73 can be detachably fastened to the female seat 74. When all the elastic buckles 6 are engaged with the slots 3, the male seat 73 is fastened into the female seat 74, and the locking strap 72 blocks all the compartments 4, forming double protection and effectively preventing the cryopreservation box from sliding out. (Refer to...) Figure 2 and Figure 7 The male and female seats 73 and 74 are designed with snaps similar to those on clothing. Simply press the male seat 73 into the female seat 74 to block all the compartments 4 with the locking strap 72. When you need to remove the compartment 4, simply turn the locking strap 72 to the side 1 of the freezer rack.

[0027] The inner wall of the frame 1 is provided with a groove 9, and the sides of the double side plates 44 are provided with a slide rail 8. The slide rail 8 is located in the groove 9. The groove 9 and the slide rail 8 are designed to cooperate with each other. Antifreeze lubricant can be applied between the groove 9 and the slide rail 8. Specifically, it can be perfluoropolyether (PFPE) lubricant or modified silicone grease, which can prevent the compartment 4 from being removed when frost forms.

[0028] During actual installation, the end of the slide rail 8 is equipped with a locking block. When the compartment 4 is pulled to its limit position, the locking block blocks the slide groove 9, thereby preventing the entire compartment 4 from being pulled out.

[0029] The panel 41 is provided with a label slot 411, which can be marked on the corresponding compartment 4 to facilitate quick location of the corresponding cryopreservation box.

[0030] The top of the frame 1 is provided with a handle 10, which facilitates the self-removal of the cryopreservation rack.

[0031] Reference Figure 6 The bottom of the frame 1 is provided with a pad 421, which is of the same thickness as the locking strap seat 71, so that the cryopreservation box remains stable when placed vertically and facilitates the rotation of the locking strap.
