Description

Technical Field

[0001] This utility model relates to a cryopreservation rack, belonging to the field of sample refrigeration technology. Background Technology

[0002] Cryopreservation racks are commonly used containers in the fields of biology and medicine for the cryopreservation of reagents and biological samples. Cryopreservation racks are generally used in conjunction with cryopreservation boxes. Cryopreservation racks are typically stored in ultra-low temperature chambers or liquid nitrogen tanks. Currently, commonly used ultra-low temperature chambers employ intelligent temperature control, and their temperature can be kept constant below -80 degrees Celsius.

[0003] Chinese patent CN201721174084.6 discloses a novel cryopreservation rack, comprising a rectangular frame with two side panels and two top panels. Several partitions are evenly arranged between the two side panels from top to bottom. Elastic clamping devices are provided on the side panels between the partitions. A stop assembly is provided on the same side of each side panel. Adjacent partitions or top panels form a cavity with the partitions, and the stop assembly corresponds one-to-one with the cavity. Cryopreservation boxes are installed within the cavity. Simple spring clips are used to fix the cryopreservation boxes, preventing accidental sliding. The cryopreservation boxes are easy to retrieve, and the combination of the slide rails and partitions allows for more flexible use of space.

[0004] In the aforementioned prior art, the degree of bending of the spring cannot be manually adjusted or controlled, and it does not have the function of adjusting the clamping force. The degree of bending of the spring depends on the width of the cryopreservation box being stored. With long-term use, the spring is prone to forming a fixed bending shape, which makes it impossible to clamp cryopreservation boxes with a smaller width. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cryopreservation rack that solves the problem that the clamping force of the cryopreservation rack in the prior art cannot be adjusted.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution: a cryopreservation rack, comprising a cryopreservation rack, wherein the cryopreservation rack is provided with a plurality of storage cavities for storing cryopreservation boxes;

[0007] An elastic sheet is disposed on the inner wall of the storage cavity. The elastic sheet includes a fixed end that is fixedly attached to the inner wall of the storage cavity and a free end that can slide back and forth.

[0008] A sliding groove is formed on the inner wall of the storage cavity and penetrates the inner wall;

[0009] A lever is fitted to the outer wall of the storage cavity and connected to the free end;

[0010] The locking part is provided on the surface where the lever and the outer side wall meet.

[0011] By adopting the above technical solution, one end of the elastic sheet is set as a free end that can slide freely and is connected to the lever. This allows the bending degree of the elastic sheet to be adjusted by moving the lever. By adjusting the bending degree of the elastic sheet, it is possible to clamp cryopreservation boxes of different widths. For cryopreservation boxes of the same width, the optimal clamping force can be adjusted to ensure that the clamping force is sufficient and to prevent the elastic sheet from bending excessively, resulting in excessive local stress and bending.

[0012] The present invention is further configured such that the length direction of the elastic sheet is parallel to the insertion direction of the cryopreservation box.

[0013] By adopting the above technical solution, the cryopreservation box can be inserted into the storage cavity more easily. The bent elastic sheet can form an arc-shaped guide plane at the fixed end, which improves the smoothness of the cryopreservation box insertion and prevents interference caused by the cryopreservation box being too wide.

[0014] The present invention is further configured such that: the lever block and the free end are connected by a connecting rod, and an elastic top plate is sleeved on the connecting rod between the free end and the inner sidewall contact surface.

[0015] By adopting the above technical solution and using the setting of the elastic top piece, the gap between the free end and the inner sidewall is maximized, so that the lever can fit tightly against the outer sidewall, thereby improving the tightness of the connection of the locking part.

[0016] The present invention is further configured such that: the elastic top plate has a through hole in the middle that is connected to the connecting rod, and the ends of both ends are bent to the same side and abut against the free end.

[0017] By adopting the above technical solution and setting the bends on both sides, the elastic force of the elastic top plate can be evenly distributed between the free end and the inner wall.

[0018] The present invention is further configured such that: the locking part includes a plurality of inverted buckles one disposed on the outer side wall and inverted buckles two disposed on the lever block.

[0019] By adopting the above technical solution, the limiting position of the push block is achieved by interlocking the first and second inverted latches.

[0020] The present invention is further configured such that the inverted buckle is tilted in the direction of the opening of the storage cavity, and the cryopreservation box is inserted into the storage cavity from the opening direction.

[0021] By adopting the above technical solution, the degree of bending of the elastic sheet can be prevented from changing, so that after the first and second inverted clips are engaged, they can only slide towards each other in the direction of increasing bending, thereby improving the stability of the cryopreservation rack in holding the cryopreservation box.

[0022] The present invention is further configured such that: top plates are provided on both sides of the lever block, the top plates are inclined relative to the side of the lever block and the height is greater than the height of the side of the lever block.

[0023] By adopting the above technical solution, by pressing the top plates on both sides, the ends of the top plates abut against the outer wall, and the entire lever is pushed away from the outer wall, thereby separating the first and second inverted buckles. At this time, the sliding lever can drive the free end to slide along the sliding groove, thereby adjusting the bending degree of the elastic sheet and thus adjusting the clamping force of the cryopreservation rack.

[0024] The present invention is further configured such that: the top plate and the lever are rotatably connected, and the top plate can be pressed and rotated around the connecting side as the center and push the lever until the lever separates from the contact surface of the outer side wall.

[0025] By adopting the above technical solution, the top plate becomes easier to press.

[0026] The present invention is further provided with an anti-slip layer on the outer surface of the lever.

[0027] By adopting the above technical solution, the friction coefficient of the lever is increased, making it easier for users to adjust the elastic plate by moving the lever.

[0028] The present invention is further configured such that the elastic fixed end is positioned close to the opening of the storage cavity.

[0029] By adopting the above technical solution, the arc transition surface formed between the fixed end and the curved part can guide the inserted cryopreservation box and improve the smoothness of the insertion of the cryopreservation box.

[0030] The beneficial effects of this utility model are:

[0031] By setting up an elastic sheet, one end of which is fixed to the inner wall and the other end is set as a free end that can move freely, it is possible to prevent the elastic sheet from bending and being damaged due to excessive local stress caused by excessive bending. At the same time, with the setting of the lever and the locking part, the bending degree of the elastic sheet can be adjusted by adjusting the sliding position of the lever in the sliding groove. By adjusting the bending degree of the elastic sheet by the lever, the clamping force of the cryopreservation box can be adjusted, so that the entire cryopreservation rack can be adjusted to different clamping forces to adapt to cryopreservation boxes of different widths.

Detailed Implementation

[0038] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0039] like Figures 1-4 As shown, a cryopreservation rack includes a cryopreservation rack 1, and the cryopreservation rack 1 is provided with a plurality of storage cavities 2 for storing cryopreservation boxes 11. The entire cryopreservation rack 1 is formed by two side plates and a plurality of supporting plates overlapping each other. The two supporting plates serve as the upper and lower bottom surfaces of the storage cavities 2, respectively, and the two side plates serve as the left and right sides of the storage cavities 2, respectively.

[0040] An elastic sheet 3 is disposed on the inner wall 210 of the storage cavity 2. The inner wall 210 is specifically the wall surface of the side plate facing the storage cavity 2. Each storage cavity 2 is provided with an elastic sheet 3. The elastic sheet 3 includes a fixed end 310 that is fixedly attached to the inner wall 210 of the storage cavity 2 and a free end 320 that can slide back and forth. Between the fixed end 310 and the free end 320 is the bent portion 330 of the elastic sheet 3. The elastic fixed end 310 is positioned close to the opening direction of the storage cavity 2.

[0041] Furthermore, a sliding groove 4 is provided on the inner sidewall 210 and the sliding groove 4 penetrates the inner sidewall 210. The free end 320 is attached to the inner sidewall 210, and a connecting rod 7 is connected to the side attached to the inner sidewall 210. The connecting rod 7 extends out of the storage cavity 2 after passing through the sliding groove 4, and a lever 5 is connected to the extended end. By sliding the lever 5, the position of the free end 320 can be adjusted, thereby changing the degree of bending of the elastic sheet 3 and changing the clamping force on the cryopreservation box 11.

[0042] Specifically, the lever 5 is fitted to the outer wall 220 of the storage cavity 2, and a locking part 6 is provided on the mating surface between the lever 5 and the outer wall 220.

[0043] The locking part 6 includes a plurality of inverted buckles 610 disposed on the outer side wall 220 and inverted buckles 620 disposed on the lever 5. The inverted buckles 610 are inclined in the direction of the opening of the storage cavity 2, and the cryopreservation box 11 is inserted into the storage cavity 2 from the opening direction.

[0044] In this embodiment, both the first inverted buckle 610 and the second inverted buckle 620 are configured as inclined, inverted-mouth-shaped locking blocks. Multiple locking blocks are arranged at equal intervals to form the first inverted buckle 610 and the second inverted buckle 620. Since the inclination direction of the first inverted buckle 610 is towards the opening direction of the storage cavity 2, when the cryopreservation box 11 is inserted into the storage cavity 2, the elastic sheet 3 will not slide due to the pushing of the cryopreservation box 11. This ensures that the elastic sheet 3 can maintain a sufficient degree of bending after the cryopreservation box 11 is inserted, and ensures that the inserted cryopreservation box 11 can be stably clamped.

[0045] By setting the tilt direction of the first inverted clip 610, when the first inverted clip 610 and the second inverted clip 620 are engaged with each other, the elastic piece 3 can only bend in the direction of increasing bending, that is, the free end 320 can only slide in the direction of the fixed end 310, thereby preventing insufficient clamping force during the clamping process of the cryopreservation box 11.

[0046] As the cryopreservation box 11 is inserted into the storage cavity 2, the side wall of the cryopreservation box 11 will fit against the bending part 330. As the cryopreservation box 11 is continuously inserted, the elastic sheet 3 will be bent in the direction of reducing the degree of bending. However, since the free end 320 of the elastic sheet 3 is locked by the locking part 6, the elastic sheet 3 will not bend, thereby improving the stability of the elastic sheet 3.

[0047] After the cryopreservation box 11 is inserted into the storage cavity 2, if the cryopreservation rack 1 shakes or tilts, the cryopreservation box 11 will tend to slide outward. At this time, the bent part 330 of the elastic sheet 3 will be subjected to frictional force from the inside of the storage cavity 2 to the outside, driving the free end 320 of the elastic sheet 3 to slide towards the fixed end 310. Since the tilting direction of the inverted 610 is towards the fixed end 310, the bending of the elastic sheet 3 will not be hindered. As the elastic sheet 3 slides towards the free end 320, its overall bending degree increases, which can further improve the clamping force of the elastic sheet 3 on the cryopreservation box 11, thereby preventing the cryopreservation box 11 from sliding out of the storage cavity 2.

[0048] It should be noted that the length direction of the elastic sheet 3 is parallel to the insertion direction of the cryopreservation box 11.

[0049] Top plates 9 are provided on both sides of the lever 5. The top plates 9 are inclined relative to the sides of the lever 5 and are higher than the sides of the lever 5. The top plates 9 and the lever 5 are rotatably connected. The top plates 9 can be pressed and rotated around the connecting side as the center, pushing the lever 5 until the lever 5 separates from the contact surface of the outer wall 220. With the setting of the top plates 9, when the user needs to take out the cryopreservation box 11, he only needs to press the top plates 9 so that the end of the top plates 9 abuts against the outer wall 220. Since the height of the top plates 9 is greater than the side height of the lever 5, after the end of the top plates 9 abuts against the outer wall 220, the lever 5 will be pushed away from the outer wall 220 by the top plates 9, so that the first buckle 610 and the second buckle 620 separate from each other. At this time, when the lever 5 is moved, the free end 320 can be moved away from the fixed end 310, so that the bending degree of the elastic sheet 3 is reduced and the clamping force is reduced, thus making it easier to take out the cryopreservation box 11.

[0050] In other embodiments, the first snap fastener 610 and the second snap fastener 620 can also be configured as square, triangular or other snap fastener shapes that are perpendicular to the contact surface between the outer wall 220 and the push block 5.

[0051] Furthermore, an elastic top plate 8 is fitted onto the connecting rod 7 between the free end 320 and the inner sidewall 210. The elastic top plate 8 has a through hole in the middle that is connected to the connecting rod 7, and its two ends are bent to the same side and then abut against the free end 320.

[0052] The elastic top piece 8 increases the fit between the first inverted clip 610 and the second inverted clip 620, preventing the first inverted clip 610 and the second inverted clip 620 from becoming loose during storage, which would result in insufficient clamping force of the elastic piece 3.

[0053] An anti-slip layer 10 is provided on the outer surface of the lever 5. This allows the user to easily move the lever 5 and quickly adjust the bending degree of the elastic piece 3.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
