Description

Technical Field

[0001] This utility model relates to the field of low-temperature refrigerator technology, and in particular to a stem cell low-temperature refrigerator. Background Technology

[0002] The low-temperature refrigerator is used for transporting stem cells. It consists of a cabinet, a lid, an ice box, a thermometer, and a storage box. When using the refrigerator, add ice crystal powder and water to the ice box, then freeze it in the freezer. After the ice box is frozen, place it into the refrigerator, then into the storage box. Next, place the test tube containing stem cells into the mounting slot in the storage box, then cover it with the top ice box, and finally close the lid. The bottom of the lid is equipped with a sealing ring that seals with the refrigerator. The temperature inside the refrigerator can be detected by the thermometer.

[0003] The inventors discovered in their daily work that when using a low-temperature refrigerator, test tubes containing stem cells are inserted into the mounting slot on the storage box. However, the mounting slot lacks a mechanism to limit the movement of the test tubes. As a result, the test tubes are subjected to bumps during transportation, causing them to shake and collide with the inside of the low-temperature refrigerator, which may lead to the test tubes breaking. Utility Model Content

[0004] The purpose of this invention is to solve the problem that, in actual use, when test tubes containing stem cells are inserted into the mounting slot of the storage box, and the mounting slot lacks a mechanism to limit the test tubes, the test tubes are subject to bumps during transportation, causing them to shake and collide with the inside of the low-temperature refrigerator, which may lead to the test tubes breaking. Therefore, this invention proposes a stem cell low-temperature refrigerator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stem cell low-temperature refrigerator, comprising a box body and a lid, wherein the inner wall of the box body is provided with a bottom ice box, a top ice box, and side ice boxes, a thermometer is installed on the front of the box body for detecting the temperature inside the box, a storage box is provided at the upper end of the bottom ice box, and a fixing component is provided at the upper end of the storage box, the fixing component including an annular groove formed in the inner wall of the storage box, an annular airbag is installed on the inner wall of the annular groove, and rubber clamps are fixedly connected to both sides of the inner arc surface of the annular airbag.

[0006] The effect achieved by the above components is as follows: by setting the fixing components, when it is necessary to fix the test tube containing stem cells in the storage box installation slot, the air intake mechanism causes the annular air bladder in the annular groove to inflate, which pushes the rubber clamp to clamp and fix the test tube, thereby achieving the effect of fixing the test tube containing stem cells as much as possible.

[0007] Preferably, the storage box has an air chamber inside, and an air tube is fixedly connected between the air chamber and the annular airbag. The upper end of the storage box has an operating groove, and a lead screw is threaded into the bottom of the inner wall of the operating groove. A piston is rotatably connected to the lower end of the lead screw.

[0008] The effect achieved by the above components is as follows: turning the screw causes the piston to move downward, which pushes the gas in the air chamber to flow through the air tube to the annular air bladder, causing the annular air bladder in the annular groove to inflate.

[0009] Preferably, a pin is inserted into the upper end of the lead screw, a plurality of evenly distributed positioning grooves are provided on the inner wall of the operating groove, and a protrusion is provided on the surface of the pin.

[0010] The effect achieved by the above components is to drag the pin so that it is inserted into the positioning groove, thereby limiting the lead screw.

[0011] Preferably, one end of the pin is fixedly connected to a spring, and the other end of the spring is fixed to the lead screw.

[0012] The effect achieved by the above components is that by setting a spring, the spring pulls the pin, thereby limiting the pin's position.

[0013] Preferably, the inner arc surface of the rubber clamp is provided with anti-slip stripes.

[0014] The effect achieved by the above components is to increase the friction between the rubber clamp and the test tube by setting anti-slip stripes.

[0015] Preferably, an assembly component is provided between the side ice box and the bottom ice box. The assembly component includes a first locking block fixedly connected to the front of the side ice box, and a first locking groove is provided on the side of the bottom ice box. The inner wall of the first locking groove is provided with a protrusion.

[0016] The effect achieved by the above components is as follows: when assembling the ice box, drag the side ice box so that the first locking block is inserted into the first locking slot of the bottom ice box, thereby fixing them together. Then the other side ice boxes are fixed to the bottom ice box, thus completing the assembly.

[0017] Preferably, the first card block has a second card slot on its front side, the inner wall of the second card slot has a protrusion, and the second card block is fixedly connected to one side of the inner wall of the first card slot.

[0018] The effect achieved by the above components is to assist in fixing the opposite side ice box and the bottom ice box by setting the second slot and the second block.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, by setting a fixing component, when it is necessary to fix the stem cell test tubes placed in the installation slot of the storage box, the air intake mechanism causes the annular airbag in the annular groove to inflate, which pushes the rubber clamp to clamp and fix the test tubes. This achieves the effect of fixing the stem cell test tubes as much as possible, solving the problem that when the stem cell test tubes are inserted into the installation slot of the storage box, the installation slot lacks a mechanism to limit the test tubes, which causes the test tubes to shake during transportation and collide with the inside of the low-temperature refrigerator, potentially causing the test tubes to break.

[0025] Reference Figure 1 As shown, this utility model provides a technical solution: a stem cell low-temperature refrigerator includes a box body 1 and a box cover 9. The inner wall of the box body 1 is provided with a bottom ice box 7, a top ice box 8 and a side ice box 6. A thermometer 4 is installed on the front of the box body 1. The thermometer 4 is used to detect the temperature inside the box body 1. A storage box 5 is provided at the upper end of the bottom ice box 7. A fixing component 2 is provided at the upper end of the storage box 5.

[0026] Reference Figure 3As shown, in this embodiment: the fixing component 2 includes an annular groove 21 formed in the inner wall of the storage box 5. An annular airbag 22 is installed on the inner wall of the annular groove 21. Rubber clamps 23 are fixedly connected to both sides of the inner arc surface of the annular airbag 22. By setting the fixing component 2, when it is necessary to fix the stem cell test tubes placed in the installation slot of the storage box 5, the annular airbag 22 in the annular groove 21 is inflated by the air intake mechanism, which pushes the rubber clamps 23 to clamp and fix the test tubes, thereby achieving the effect of fixing the stem cell test tubes as much as possible. An air chamber 24 is formed inside the storage box 5. An air tube 25 is fixedly connected between the air chamber 24 and the annular airbag 22. An operating groove 28 is formed at the upper end of the storage box 5. A screw rod 27 is threaded into the bottom of the inner wall of the operating groove 28. The lower end of the screw rod 27 is rotatably connected to... Piston 26, when turned, rotates screw 27, causing piston 26 to move downwards. This pushes the gas in gas chamber 24 through gas pipe 25 to annular gas bladder 22, causing annular gas bladder 22 in annular groove 21 to inflate. Pin 210 is inserted into the upper end of screw 27. Multiple evenly distributed positioning grooves are formed on the inner wall of operating groove 28. The surface of pin 210 is provided with protrusions. Dragging pin 210 causes it to be inserted into the positioning groove, thereby limiting screw 27. One end of pin 210 is fixedly connected to spring 29, and the other end of spring 29 is fixed to screw 27. By setting spring 29, spring 29 pulls pin 210, thus limiting pin 210. The inner arc surface of rubber clamp 23 is provided with anti-slip stripes, which increases the friction between rubber clamp 23 and test tube.

[0027] Reference Figure 2 As shown in this embodiment: an assembly component 3 is provided between the side ice box 6 and the bottom ice box 7. The assembly component 3 includes a first locking block 31 fixedly connected to the front of the side ice box 6, and a first locking groove 33 opened on the side of the bottom ice box 7. The inner wall of the first locking groove 33 is provided with a protrusion. When assembling the ice boxes, the side ice box 6 is dragged so that the first locking block 31 is locked into the first locking groove 33 of the bottom ice box 7, thereby fixing them together. Then the other side ice boxes 6 are fixed to the bottom ice box 7, thereby completing the assembly. A second locking groove 32 is opened on the front of the first locking block 31. The inner wall of the second locking groove 32 is provided with a protrusion. A second locking block 34 is fixedly connected to one side of the inner wall of the first locking groove 33. By setting the second locking groove 32 and the second locking block 34, the side ice box 6 and the bottom ice box 7 are fixedly fixed.

[0028] Working principle:

[0029] When using the low-temperature refrigerator, add ice crystal powder and water to the ice box, then place it in the freezer compartment to freeze. After freezing, place the ice box into the refrigerator body 1, then into the storage box 5. Next, place the test tubes containing stem cells into the mounting slots inside the storage box 5. Then, cover the top with the ice box 8, and finally cover with the lid 9. The lower end of the lid is equipped with a sealing ring that seals with the refrigerator body 1, thus refrigerating the test tubes containing stem cells at low temperatures. The temperature inside the refrigerator body 1 can be detected by the thermometer 4. When it is necessary to fix the test tubes containing stem cells in the mounting slots of the storage box 5, turn the screw 27 to make the piston 26 move downward, causing the gas in the gas chamber 24 to be pushed by the piston 26 and flow through the gas tube 25 to the annular air bladder 22, causing the annular air bladder 22 in the annular groove 21 to inflate. This causes the rubber clamp 23 to be pushed, clamping and fixing the test tube, thereby achieving the effect of fixing the test tube containing stem cells as much as possible. Dragging the pin 210 causes it to be inserted into the positioning groove, thereby limiting the lead screw 27. By setting the spring 29, the spring 29 pulls the pin 210, thus limiting the pin 210. By setting anti-slip stripes, the friction between the rubber clamp 23 and the test tube is increased. When assembling the ice box, dragging the side ice box 6 causes the first locking block 31 to be inserted into the first locking groove 33 of the bottom ice box 7, thereby fixing them together. Then the other side ice boxes 6 are fixed to the bottom ice box 7, thus completing the assembly. By setting the second locking groove 32 and the second locking block 34, the side ice boxes 6 and the bottom ice box 7 are further fixed.
