Technical Field

[0001] The utility model relates to the technical field of test tube preservation, and in particular to a test tube preservation device for genetic engineering. Background Art

[0002] Genetic engineering, also known as gene splicing technology and DNA recombination technology, is a genetic technology based on the theory of molecular genetics and the modern methods of molecular biology and microbiology. It constructs hybrid DNA molecules in vitro according to a pre-designed blueprint using genes from different sources, and then introduces them into living cells to change the original genetic characteristics of organisms, obtain new varieties, and produce new products. Test tubes are commonly used instruments in chemical laboratories as reaction containers for small amounts of reagents, while storage devices are used to store test tubes containing reagents.

[0003] The existing patent publication number CN217042687U provides a test tube storage device for genetic engineering, which relates to the field of genetic engineering technology, including a storage box, a sealed cabinet door and a fixed rack. The front end of the storage box is hingedly provided with a sealed cabinet door, and the top of the storage box is fixedly installed with a fixed rack. A disassembly and storage mechanism is provided inside the storage box. The disassembly and storage mechanism is composed of a slide groove, a placement rack, a slider and a bolt. Slide grooves are fixedly installed on the upper and lower sides of the inner side of the storage box, and a placement rack is provided between the slide grooves. In this utility model, the staff brings the test tube containing cells to the vicinity of the storage box, opens the sealed cabinet door, unscrews the bolts out of the front end of the slider and the front end thread groove of the slide groove, slides the sliders at both ends of the placement rack out of the slide groove, and then places the test tube on the placement rack and pushes the placement rack to make the sliders at both ends of the placement rack slide into the slide groove, and screws the bolts into the front end of the slider and the front end thread groove of the slide groove to fix it.

[0004] The above solution has the following problems during implementation: the device fixes the slider in the slide groove by bolts to fix the placement rack for the test tubes. However, the placement rack needs to be pulled out when placing and removing the test tubes. At this time, a tool needs to be used to unscrew the bolts, and then the placement rack is pulled to drive the slider to slide in the slide groove. After placement, the placement rack is pushed back, and a tool still needs to be used to tighten the bolts to fix the placement rack. This operation is more troublesome, time-consuming, and inconvenient, which greatly reduces the practicality of the device. To this end, we provide a test tube storage device for genetic engineering to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a test tube storage device for genetic engineering, comprising a storage box 1, a box door 11 is installed at the opening of the storage box 1 through a hinge, a cooling assembly 2 for cooling the interior of the storage box 1 is installed from the top of the storage box 1 to the bottom of the storage box 1, the cooling assembly 2 includes a cooling water tank 21, the cooling water tank 21 is installed at the top of the storage box 1, a water pump 22 is installed at the top of the cooling water tank 21, and a connecting pipe 23 is connected between the input end of the water pump 22 and the cooling water tank 21, and the output end of the water pump 22 is connected to a water cooling pipe 24, and the water outlet of the water-cooling pipe 24 is connected to the cooling water tank 21 through-holes. A mounting groove 12 is provided between the inner wall and the outer wall of the storage box 1, and the water-cooling pipe 24 is provided in the mounting groove 12. This structure makes it possible to cool the storage box 1, and through circulating cooling, the low temperature in the storage box 1 can be better maintained, so that the test tubes containing reagents can be better preserved. Through holes are provided on both sides of the inner wall of the storage box 1, and the mounting groove 12 is connected to several groups of through holes, so that cold air can better enter the storage box 1 and cool the inside of the storage box 1.

[0023] As an implementation method in this embodiment, Figure 2 and Figure 3As shown, the upper and lower sides of the storage box 1 are equipped with placement mechanisms for supporting the placement of test tubes. Each group of placement mechanisms includes a placement component 3 for placing the test tubes, two groups of pulling components 4 for pulling out the placement component 3, and a locking component 5 for locking and fixing the placement component 3. The placement component 3 includes a placement rack 31, which is installed between the two groups of pulling components 4. The surface of the placement rack 31 is equidistantly penetrated with plug holes 32. The bottom end of the placement rack 31 is connected to the corresponding positions of several groups of plug holes 32. The surface of the rubber rack 33 is equidistantly provided with air holes 34. This structure can be used to place test tubes, so that the test tubes can be placed more neatly and are easier to find. The air holes 34 allow cold air to better contact the test tubes, so that the test tubes filled with reagents can be placed neatly. The preservation effect is better. The two groups of pulling components 4 both include fixed rods 41. The two groups of fixed rods 41 are fixedly connected to the two sides of the inner wall of the storage box 1 respectively. The ends of the two groups of fixed rods 41 close to each other are provided with a slide groove 1 42. The two groups of slide grooves 1 42 are slidably installed with sleeve rods 43. The ends of the two groups of sleeve rods 43 close to each other are provided with a slide groove 2 44. The two groups of slide grooves 2 44 are slidably installed with sliders 45. The two groups of sliders 45 are respectively connected to the two ends of the placement rack 31, and the outer ends of the two groups of sliders 45 are connected to connecting blocks 46. This structure makes it possible to pull the placement rack 31 out of the storage box 1 and away from the storage box 1 for a distance. At the same time, the placement rack 31 can be supported after being pulled out without the need for hand support. This makes it more convenient to place and take out the test tubes, greatly increasing the convenience of the device.

[0024] As an implementation method in this embodiment, Figure 4 and Figure 5As shown, the locking assembly 5 is installed at the top of one group of connecting blocks 46 and one group of fixed rods 41. The locking assembly 5 includes a limit frame 51 and a card block 55. The limit frame 51 is connected to the side of the top of the fixed rod 41 close to the connecting block 46. A movable rod 52 is slidably installed on the upper side of the limit frame 51, and a spring 53 is sleeved on the surface of the movable rod 52. The bottom end of the movable rod 52 is connected to the limit block 54. The spring 53 is arranged between the limit frame 51 and the limit block 54, and the two ends of the spring 53 are respectively against the inner wall of the limit frame 51 and the top of the limit block 54. The card block 55 is connected to the top of the connecting block 46. The card block 55 is inserted in the limit frame 51 and against the limit block 54. This structure makes it possible to fix the placement rack 31 on the storage box 1 The top of the movable rod 52 passes through the limit frame 51 and is provided with a handle 56. This structure makes it more convenient to pull the handle 56 to drive the movable rod 52. T-slots 57 are provided on both sides of the inner wall of the limit frame 51. T-blocks 58 are connected to both ends of the limit block 54. The two groups of T-blocks 58 are slidably installed in the two groups of T-slots 57 separately, so that the limit block 54 can move longitudinally in the limit frame 51 more stably, thereby making the fixation of the placement rack 31 more stable.

[0025] It should be noted that a little space needs to be reserved between the bottom end of the limit block 54 and the top end of the fixing rod 41 so that the clamping block 55 can be better inserted into the limit frame 51 to push the limit block 54 .

[0026] Working principle: If you need to store a test tube, you only need to hold the handle 56 and pull it upward. The handle 56 drives the movable rod 52, and the movable rod 52 drives the limit block 54 to move upward and compress the spring 53 until the limit block 54 moves above the block 55. In this way, you can pull the placement rack 31, and the placement rack 31 drives the slider 45 to slide in the second slide groove 44. At this time, the slider 45 will also drive the connecting block 46, and the connecting block 46 drives the block 55 to be pulled out of the limit frame 51 and away from it until the slider 45 moves to abut against the inner wall of the second slide groove 44. You can continue to pull, so that the slider 45 drives the sleeve rod 43 to slide in the first slide groove 42 until the sleeve rod 43 is pulled to abut against the inner wall of the first slide groove 42. At this time, the slider 45 has been away from the fixed rod 41. , the placement rack 31 is also pulled out from the storage box 1. At this time, the test tube is inserted into the insertion hole 32 and placed in the rubber sleeve 33 to complete the storage. Then the placement rack 31 is pushed back into the storage box 1. The placement rack 31 drives the slider 45 to move into the second slide groove 44, and then drives the sleeve rod 43 to move into the first slide groove 42 until the connecting block 46 fits and abuts against the fixing rod 41. At this time, the connecting block 46 drives the card block 55 to be inserted into the limit frame 51, and at the same time pushes the limit block 54 to move upward to compress the spring 53 until the protrusion of the card block 55 passes through the limit frame 51. The limit block 54 is pushed downward by the restorative force of the spring 53 to fit and abut against the card block 55, so that the card block 55 can be clamped out, thereby fixing the placement rack 31.

[0027] Then close the box door 11, and start the cooling water tank 21 and the water pump 22. The water pump 22 draws the cooling water from the cooling water tank 21 through the connecting pipe 23 and transports it to the water cooling pipe 24, so that the cooling water surrounds the inner wall of the storage box 1. After cooling the inside of the storage box 1, the cooling water flows back to the cooling water tank 21 through the water cooling pipe 24 for circulating cooling treatment, so that the storage effect is better.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
