Abstract
Description
Technical Field
[0001] This utility model relates to the field of cell cryopreservation box technology, and in particular to a cell cryopreservation box. Background Technology
[0002] Cell cryopreservation boxes are innovative products that use programmed gradient cooling to perfectly freeze cells during the storage process.
[0003] When using a cryopreservation box to store and freeze test tubes containing cells and tissues, the test tubes are inserted into the placement slots, the lid is closed, and the cryopreservation box is placed in a freezer for freezing. Since the size of the test tubes used to hold cells and tissues is usually not fixed, while the size of the placement slots on the cryopreservation box is fixed, smaller test tubes may tilt when placed in the placement slots. Also, when picking them up and transporting them, the test tubes may shake in the placement slots and impact the inner wall, causing damage. This makes traditional cryopreservation boxes inconvenient to use and have poor applicability. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cell cryopreservation box.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cell cryopreservation box, comprising a cryopreservation box body and a box body, wherein a plurality of placement slots are provided on one side of the cryopreservation box body, one end of the outer surface of the cryopreservation box body is inserted into the inner wall of the box cover, an adjustment device is provided inside the cryopreservation box body, a limiting device is provided between the box cover and the cryopreservation box body, the adjustment device includes a plurality of adjustment limiting rods, a rectangular cavity is provided inside the cryopreservation box body, a plurality of sliding holes are provided on both sides of the inner wall of the rectangular cavity, threaded rods are fixedly connected to both sides of the adjustment limiting rods, the adjustment limiting rods and the two threaded rods are slidably connected to the inner walls of the rectangular cavity and the two sliding holes respectively, and a threaded hole block is threadedly connected to the outer surface of the threaded rod.
[0006] The aforementioned components achieve the following effect: By setting up an adjustment device, when using the cryopreservation box body to store and freeze test tubes containing cell tissues, the test tubes are inserted into the placement slots. Then, depending on the size of the test tubes, the two threaded rods are held and slid to one side in the sliding holes to a certain position, causing the adjusting limit rod to also slide to one end in the rectangular cavity to a certain position, so that several inner walls on one side are tightly attached to the surface of the placed test tubes, clamping and fixing them. At this time, the screw hole block is turned to a certain position, so that one side abuts against the two sides of the cryopreservation box body, limiting and fixing the adjusting limit rod. Thus, test tubes of different sizes can be fixed and limited in the placement slots, making them less prone to shaking when handled and improving the stability of use. By adjusting several adjusting limit rods individually, the cryopreservation box body can store and limit test tubes of different sizes at one time, improving the applicability of the cryopreservation box body. After placement, the lid is closed, and finally the cryopreservation box body is placed in the freezer for freezing and storage.
[0007] Preferably, a plurality of screw blocks are fixedly connected to the outer surface of the screw hole block, and the plurality of screw blocks are arranged at equal intervals.
[0008] The effect achieved by the above components is that by setting the screw block, the contact area of the outer surface of the screw hole block can be increased, making it easier to hold and screw it manually.
[0009] Preferably, one end of the threaded rod is fixedly connected to a limiting block, and the outer surface dimension of the limiting block is larger than the inner wall dimension of the threaded hole block.
[0010] The effect achieved by the above components is that by setting a limiting block, the screw hole block can be limited on the threaded rod, making it less likely to fall off or be lost.
[0011] Preferably, several anti-slip blocks are fixedly connected to several inner walls on one side of the adjusting limit rod, and the anti-slip blocks are made of rubber.
[0012] The effect achieved by the above components is that by setting anti-slip blocks, the contact friction of several inner walls on one side of the adjusting limit block can be increased, making it more secure and stable when it is pressed against the outer surface of the test tube.
[0013] Preferably, the limiting device includes two locking blocks, and round hole blocks are fixedly connected to both sides of the box cover. The inner wall of the round hole block is slidably connected to one end of the locking block. The body of the cryopreservation box has slots on both sides, and one end of the locking block is inserted into the inner wall of the slot.
[0014] The effect achieved by the above-mentioned components is as follows: By setting a limiting device, after the test tube containing cells is placed in the placement slot, when it needs to be frozen, the lid can be placed on the top outer surface of the cryopreservation box body. Then, the locking block can be manually slid in the slot to a certain position, and one end can be inserted into the slot to limit the lid on the cryopreservation box body, making the lid less likely to shake. This facilitates the freezing and storage of the cryopreservation box body. At the same time, when it is necessary to remove the lid, simply pull out the locking block to remove it. This makes it easy to install and remove the lid, and is convenient to operate and use the cryopreservation box body.
[0015] Preferably, a spring is sleeved and connected to the outer surface of one end of the card block, and the two ends of the spring are fixedly connected to one side of the card block and one side of the circular hole block, respectively.
[0016] The effect achieved by the above components is that, by setting a spring, after the card block is inserted into the card slot, the spring can reset and limit it in the card slot, making it less likely to slip out or fall off.
[0017] Preferably, one end of the locking block has a triangular cross-section, and the dimension of the end of the locking block closer to the spring is larger than the dimension of the other end.
[0018] The effect achieved by the above components is that by setting the locking block in a triangular shape, when the lid is closed, when one side of the locking block abuts against the bottom side of the cryopreservation box body, it will be automatically squeezed and contracted, causing the spring to contract, making it easier and more convenient to close the lid, and it can be installed and fixed without pulling the locking block.
[0019] Preferably, a pull rope is fixedly connected to one side of the card block, and one end of the pull rope is fixedly connected to one side of the round hole block.
[0020] The effect achieved by the above-mentioned components is as follows: by setting a pull rope, after the card block is inserted into the card slot, when it is necessary to open the box cover, the pull rope can be pulled to slide the card block outward in the inner wall of the round hole block to a certain position, so that one end of it can be pulled out of the card slot, making it convenient to pull the card block.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting an adjustment device, when using the cryopreservation box body to store and freeze test tubes containing cell tissues, the test tubes are inserted into the placement slots. Then, according to the size of the test tubes, the two threaded rods are held and slid to one side in the sliding holes to a certain position, causing the adjusting limit rod to also slide to one end in the rectangular cavity to a certain position, so that several inner walls on one side are tightly attached to the surface of the placed test tubes, clamping and fixing them. At this time, the screw hole block is turned to a certain position, so that one side abuts against the two sides of the cryopreservation box body, limiting and fixing the adjusting limit rod. Thus, test tubes of different sizes can be fixed and limited in the placement slots, making them less prone to shaking when handled and improving the stability of use. By adjusting several adjusting limit rods individually, the cryopreservation box body can store and limit test tubes of different sizes at one time, improving the applicability of the cryopreservation box body. After placement, the lid is closed, and finally the cryopreservation box body is placed in the freezer for freezing and storage. Attached Figure Description

Detailed Implementation
[0029] Example 1, as Figure 1-5As shown, a cell cryopreservation box includes a cryopreservation box body 1 and a box body. Several placement slots 4 are opened on one side of the cryopreservation box body 1. One end of the outer surface of the cryopreservation box body 1 is inserted into the inner wall of the box cover 5. An adjustment device 2 is provided inside the cryopreservation box body 1. A limit device 3 is provided between the box cover 5 and the cryopreservation box body 1. The adjustment device 2 includes several adjustment limit rods 22. A rectangular cavity 21 is opened inside the cryopreservation box body 1. Several sliding holes 28 are opened on both sides of the inner wall of the rectangular cavity 21. Threaded rods 23 are fixedly connected to both sides of the adjustment limit rods 22. The adjustment limit rods 22 and the two threaded rods 23 are slidably connected to the inner walls of the rectangular cavity 21 and the two sliding holes 28, respectively. Threaded hole blocks 24 are threadedly connected to the outer surface of the threaded rods 23. When using the cryopreservation box body 1 to store and freeze test tubes containing cells and tissues, the test tubes are inserted into the placement slot 4. Then, depending on the size of the test tubes, the two threaded rods 23 are held and slid to one side in the sliding hole 28 to a certain position, causing the adjusting limit rod 22 to also slide to one end in the rectangular cavity 21 to a certain position, so that several inner walls on one side are tightly attached to the surface of the placed test tubes, clamping and fixing them. At this time, the screw hole block 24 is turned to a certain position, so that one side abuts against the two sides of the cryopreservation box body 1, limiting and fixing the adjusting limit rod 22. Thus, test tubes of different sizes can be fixed and limited in the placement slot 4, making them less prone to shaking when handled and improving the stability of use. By adjusting several adjusting limit rods 22 individually, the cryopreservation box body 1 can store and limit test tubes of different sizes at one time, improving the applicability of the cryopreservation box body 1. After placement, the lid 5 is closed, and finally the cryopreservation box body 1 is placed in the freezer for freezing and storage.
[0030] Reference Figure 2 and Figure 3 As shown in the figure, this embodiment discloses that a plurality of screw blocks 25 are fixedly connected to the outer surface of the screw hole block 24, and the plurality of screw blocks 25 are arranged at equal intervals. By setting the screw blocks 25, the contact area of the outer surface of the screw hole block 24 can be increased, making it easier to manually hold and screw it. One end of the threaded rod 23 is fixedly connected to a limiting block 26, and the outer surface dimension of the limiting block 26 is larger than the inner wall dimension of the screw hole block 24. By setting the limiting block 26, the screw hole block 24 can be limited on the threaded rod 23, making it less likely to fall off or be lost.
[0031] Reference Figure 2 and Figure 3 As shown, this embodiment discloses that several anti-slip blocks 27 are fixedly connected to several inner walls on one side of the adjusting limit rod 22. The anti-slip blocks 27 are made of rubber. By setting the anti-slip blocks 27, the contact friction of several inner walls on one side of the adjusting limit block 26 can be increased, making it more secure and stable when it abuts against the outer surface of the test tube.
[0032] Reference Figure 4 and Figure 5 As shown, this embodiment discloses a limiting device 3 including two locking blocks 33. Round hole blocks 32 are fixedly connected to both sides of the lid 5. The inner wall of the round hole block 32 is slidably connected to one end of the locking block 33. Locking grooves 31 are provided on both sides of the cryopreservation box body 1, and one end of the locking block 33 is inserted into the inner wall of the locking groove 31. After placing the test tube containing cells in the placement slot 4, when freezing is required, the lid 5 can be placed on the top outer surface of the cryopreservation box body 1. Then, the locking block 33 is manually slid into the locking groove 31 to a certain position, and one end is inserted into the locking groove 31, limiting the lid 5 to the cryopreservation box body 1, preventing it from shaking and facilitating freezing storage. When the lid 5 needs to be removed, simply pull out the locking block 33 to remove it, making installation and removal of the lid 5 convenient, operation-friendly, and easy to use.
[0033] Reference Figure 4 and Figure 5 As shown, this embodiment discloses a spring 34 sleeved on the outer surface of one end of the locking block 33. The two ends of the spring 34 are fixedly connected to one side of the locking block 33 and one side of the round hole block 32, respectively. By setting the spring 34, after the locking block 33 is inserted into the locking groove 31, the spring 34 can reset and limit it within the groove 31, preventing it from slipping out or falling off. One end of the locking block 33 has a triangular longitudinal section, with the dimension of the end of the locking block 33 near the spring 34 being larger than the other end. By setting the locking block 33 to a triangular shape, when the lid 5 is closed, when one side of the locking block 33 abuts against the bottom side of the cryopreservation box body 1, it will automatically be squeezed and contracted, causing the spring 34 to contract. This makes closing the lid 5 simpler and more convenient, as it can be installed and fixed without pulling the locking block 33. A pull rope 35 is fixedly connected to one side of the locking block 33, and one end of the pull rope 35 is fixedly connected to one side of the round hole block 32. By setting the pull cord 35, after the card block 33 is inserted into the card slot 31, when it is necessary to open the box cover 5, the pull cord 35 can be pulled to slide the card block 33 outward in the inner wall of the round hole block 32 to a certain position, so that one end of it is pulled out of the card slot 31, making it convenient to pull the card block 33.
[0034] Working principle: When using the cryopreservation box body 1 to store and freeze test tubes containing cells and tissues, the test tubes are inserted into the placement slot 4. Then, depending on the size of the test tubes, the two threaded rods 23 are held and slid to one side in the sliding hole 28 to a certain position. This causes the adjusting limit rod 22 to also slide to one end in the rectangular cavity 21 to a certain position, so that several inner walls on one side and the anti-slip block 27 are tightly attached to the surface of the placed test tubes, clamping and fixing them in place. At this time, the screw block 24 is screwed to a certain position by holding the screw block 25. Place one side of the cryopreservation box body 1 against both sides to fix the adjusting limit rod 22, thereby fixing test tubes of different sizes in the placement slot 4, making them less prone to shaking when handled and improving stability. By adjusting several adjusting limit rods 22 individually, the cryopreservation box body 1 can store test tubes of different sizes at one time and fix them in place, improving the applicability of the cryopreservation box body 1. After placement, close the lid 5 and finally place the cryopreservation box body 1 in the freezer for freezing.
[0035] After placing the test tube containing cells in the placement slot 4, when freezing is required, the lid 5 can be placed on the top outer surface of the cryopreservation box body 1. When one side of the locking block 33 abuts against the bottom side of the cryopreservation box body 1, it will be automatically squeezed and contracted, causing the spring 34 to contract. After sliding to a certain position, under the reset action of the spring 34, it can be locked into the locking slot 31, limiting the lid 5 on the cryopreservation box body 1, making the lid 5 less prone to shaking, facilitating the freezing storage of the cryopreservation box body 1. At the same time, when it is necessary to remove the lid 5, simply pull out the locking block 33 to remove it, making the installation and removal of the lid 5 convenient, easy to operate, and convenient to use the cryopreservation box body 1.
