Technical Field

[0001] The utility model relates to a storage rack structure, in particular to a storage rack structure in a refrigerator, belonging to the technical field of storage racks. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature. A petri dish is a laboratory dish used for culturing microorganisms or cells. In biological experiments, petri dishes and test tubes are usually used. Biological test tubes and petri dishes are stored in small refrigerators to ensure their activity and facilitate subsequent use.

[0003] The existing patent CN213657248U discloses a refrigerator storage rack that is easy to take out. The utility model has the advantage of being easy to take out items by arranging a refrigerator, a support block, a sliding rod mechanism, a sliding rod, a ball bearing, a storage rack body, a handle and a silicone sleeve. It solves the problem that the existing storage rack cannot be pulled out for use when in use, and it is troublesome to take out items when the items are in the refrigerator, which reduces the efficiency of the refrigerator storage rack and is inconvenient for users to use.

[0004] When using the current refrigerator storage rack, although the rack can be pulled out for use, due to its relatively long depth, it is necessary to reach into the innermost part of the refrigerator to take out the culture dishes and test tubes at the innermost position of the rack, which is relatively inconvenient and leads to poor practicality.

The test tube hole 27 is provided with an elastic pad 81 on the inner wall of the test tube hole 27, and the elastic pad 81 is adhered to the inner wall of the test tube hole 27. 81 can squeeze the test tube of the test tube hole 27 and restrict it to prevent the test tube from escaping from the test tube hole 27. Grooves 41 are respectively provided on both sides of the top of the horizontal plate 25. A slide rod 42 is slidably connected in the groove 41. A second spring 43 is sleeved on the outside of the slide rod 42. A pressure plate 44 is fixedly connected to the top of the slide rod 42. The two ends of the second spring 43 are respectively fixedly connected to the slide rod 42 and the inner wall of the groove 41. The cross-sectional shapes of the slide rod 42 and the groove 41 are both T-shaped. By pulling the pressure plate 44 upward, the slide rod 42 can be driven to move upward, and then the second spring 43 can be squeezed to make it The reaction force generated by the deformation of the second spring 43 can drive the pressure plate 44 to press the culture dish, thereby preventing the culture dish from shifting or detaching from the culture dish groove 26. A support groove 61 is provided on the top of the support plate 11, and support blocks 62 are slidably connected on both sides of the support groove 61. A connecting block 63 is fixedly connected between the support block 62 and the disc 22. When the disc 22 rotates, the connecting block 63 and the support block 62 can be driven to rotate synchronously. The connecting block 63 and the support block 62 can support and guide the disc 22 to prevent the disc 22 from tilting and ensure that the disc 22 can rotate stably.

[0029] When the utility model is in use: by pulling the pressure plate 44 upward, the pressure plate 44 can drive the sliding rod 42 upward, and the sliding rod 42 can squeeze the second spring 43 when it moves upward. The second spring 43 will be deformed after being squeezed, and then the culture dish can be placed in the culture dish groove 26, and the pressure plate 44 is released. The second spring 43 can pull the pressure plate 44 downward, and then the culture dish can be pressed to prevent it from moving. Repeating the above steps can place multiple culture dishes in the culture dish groove 26 in turn, and then the test tube can be inserted into the corresponding test tube hole 27. The elastic pad 81 can limit the test tube. When the corresponding culture dish or test tube needs to be taken later, the disc 22 can be rotated, and the disc 22 can drive the test tube and culture dish thereon to rotate, and then the culture dish and test tube near the inside of the refrigerator body 1 can be turned to the outside, which is convenient for relevant personnel to take.

[0030] Please refer again Figure 1 、 Figure 2 、 Figure 3 as well as Figure 5 The positioning components include a fixing plate 31 fixedly connected to both sides of the inner wall of the refrigerator body 1, a slot 32 opened on one side of the fixing plate 31, an inserting plate 33 fixedly connected to both sides of the support plate 11, a slide groove 34 opened on one side of the inserting plate 33, a push rod 35 connected to the slide groove 34, a first spring 36 fixedly connected to one end of the push rod 35, a positioning ball 37 fixedly connected to the other end of the push rod 35, and a positioning port 38 opened on one side of the slot 32. The push rod 35 is slidably connected to the slide groove 34. The cross-sections of the push rod 35 and the slide groove 34 are both T-shaped. The inserting plate 33 can be inserted into the slot 32. The positioning ball 37 can drive the push rod 35 to move under the extrusion of the slot 32, and then can squeeze the first spring 36 to deform it, and the first spring 36 can be reset. The positioning ball 37 is driven to reset and the positioning ball 37 is inserted into the positioning port 38, thereby fixing the support plate 11 to prevent the support plate 11 from moving at will, thereby allowing the culture dish and test tube to be stored stably. An auxiliary portion 71 is provided on one side of the positioning port 38, and the auxiliary portion 71 is arc-shaped. The auxiliary portion 71 can facilitate the positioning ball 37 to be inserted into or out of the positioning port 38, making the installation and disassembly of the support plate 11 relatively time-saving and labor-saving. A plurality of rolling grooves 51 are evenly arranged on both sides of the slot 32, and a sliding bead 52 is provided in the rolling groove 51. The sliding bead 52 is in contact with the insert plate 33. When the insert plate 33 moves, the sliding bead 52 can be driven to roll, which can reduce the friction of the movement of the insert plate 33 and thus improve its service life.

[0031] When the present invention is in use: align the inserting plate 33 with the slot 32 and insert the inserting plate 33 into the slot 32. The positioning ball 37 will be retracted into the slide groove 34 under the pressure of the slot 32. The movement of the positioning ball 37 can drive the push rod 35 to slide in the slide groove 34, thereby squeezing the first spring 36. The first spring 36 will be deformed after being squeezed. When the positioning ball 37 contacts the positioning hole 38, the first spring 36 resets and can drive the positioning ball 37 to be stuck in the positioning hole 38, thereby restricting and fixing the inserting plate 33 and the support plate 11 to prevent them from shifting, thereby ensuring the stable storage of the culture dish and test tube. When the inserting plate 33 moves, the sliding ball 52 can roll, which can reduce the friction of the moving of the inserting plate 33.

[0032] Working principle: First, the support plate 11 can be connected and fixed to the refrigerator body 1, and the plug plates 33 on both sides of the support plate 11 are aligned with the slots 32 and inserted into the slots 32. Due to the existence of the slots 32, the positioning ball 37 can drive the push rod 35 to move, so that the push rod 35 squeezes the first spring 36 to deform. When the positioning ball 37 contacts the positioning hole 38, the first spring 36 can push the positioning ball 37 to fit into the positioning hole 38, which can restrict and fix the support plate 11. Then, the pressure plate 44 can be pulled to deform the second spring 43. Then, the culture dish can be placed in the culture dish slot 26 and the pressure can be released. Plate 44, the second spring 43 can pull the pressure plate 44 downward to press down and fix the culture dish to prevent it from shifting, and then multiple culture dishes can be placed in different culture dish slots 26 in turn, and then multiple test tubes can be inserted into different test tube holes 27 respectively, and then the door of the refrigerator body 1 can be closed. When you need to take them out later, you can rotate the disc 22 according to actual needs, and then you can move the culture dishes and test tubes in the inner position to the door of the refrigerator body 1, and pull the pressure plate 44 again to release the culture dish, and then take out the corresponding culture dish. The operation is convenient and quick, and there is no need to put your hands into the innermost part of the refrigerator.
