A sealing baffle is installed at the front end of the placement drawer through screws. Two supporting blocks are symmetrically installed by injection molding at the ends where the sealing baffle and the placement drawer are close to each other. Two supporting bars are placed on the tops of the four supporting blocks. The tops of the two supporting bars are installed with the same placement board through injection molding. A trapezoidal bar is installed at the top of the placement drawer and away from the sealing baffle through screws. The utility model controls the sealing plate to move down by a plurality of springs and stably fits on the top of the test tube inside the placement groove, avoiding the problem of solution leakage inside the test tube during transportation.

[0004] In the existing related technologies, the following defects often exist: during the actual use of the exosome storage device, the placement holes on the test tube rack for placing test tubes often have a fixed hole size. When the test tube for storing exosomes is relatively small, the test tube is likely to shake or skew when placed inside the placement hole, thereby reducing the stability of placing and using the test tube.

DETAILED DESCRIPTION

[0031] Reference Figure 1 As shown, the utility model provides a technical solution: an exosome storage device, comprising a storage box 1, a drawer frame 2 is slidably mounted on the inner side of the storage box 1, an adjustment device 3 is provided on the inner side of the drawer frame 2, and a locking structure 4 is provided on the surface of the storage box 1.

[0032] The specific configuration and function of the adjustment device 3 and the locking structure 4 will be described in detail below.

[0033] Reference Figures 1-5 As shown, in this embodiment: the adjustment device 3 includes a limit frame 31 fixedly connected to the inner side of the storage box 1, and a draw plate 32 is slidably connected to the inside of the limit frame 31. A plurality of first placement holes 37 are evenly opened on the surface of the limit frame 31, and a plurality of second placement holes 38 are evenly opened on the surface of the draw plate 32. Both the first placement holes 37 and the second placement holes 38 are diamond-shaped structures. The diamond-shaped gap formed between the first placement hole 37 and the second placement hole 38 will be adjusted as the draw plate 32 moves inside the limit frame, and the test tube is placed inside the first placement hole 37 and the second placement hole 38, thereby facilitating the stable storage of test tubes of different sizes.

[0034] The side wall of the limit frame 31 is fixedly connected with a connecting block 34, and the side wall of the draw plate 32 is fixedly connected with a fixing block 33. The internal thread of the fixing block 33 is connected with a screw rod 35, and the screw rod 35 is rotatably connected to the inside of the connecting block 34. The screw rod 35 drives the fixing block 33 to move, thereby realizing the pulling and moving work of the draw plate 32 inside the limit frame 31. The other end of the screw rod 35 is fixedly connected with a rotating block 36. The rotating block 36 is rotated, and the setting of the rotating block 36 facilitates the driving and rotating work of the screw rod 35. Two rubber blocks 39 are glued to the inner side of the first placement hole 37, and the outer side of the rubber block 39 is a spherical structure. By providing the rubber block 39 with a spherical structure, the stability of storing the test tube is further improved.

[0035] Reference Figures 1-2 and Figure 6As shown in the figure, specifically, the buckle structure 4 includes two connecting bars 42 fixedly connected to the upper surface of the storage box 1. A rectangular plate 41 is fixedly connected to the upper sides of the two connecting bars 42. A retaining frame 44 is slidably connected inside the rectangular plate 41. The retaining frame 44 shields the outside of the drawer frame 2, thereby enabling the buckling of the drawer frame 2 inside the storage box 1. A spring 45 is fixedly connected between the retaining frame 44 and the rectangular plate 41. The retaining frame 44 is blocked outside the drawer frame 2 under the elastic force of the spring 45 on the rectangular plate 41. A support frame 43 is slidably connected inside the retaining frame 44. The support frame 43 is in an "L" shape. Slide the support frame 43 inside the retaining frame 44 and support the support frame 43 on the surface of the rectangular plate 41. At this time, the temporary support for the lifted retaining frame 44 can be achieved.

[0036] Working principle: When storing test tubes of different sizes, first rotate the rotating block 36. The setting of the rotating block 36 facilitates the driving rotation of the lead screw 35. The lead screw 35 will drive the fixed block 33 to move, and then the sliding movement of the extraction plate 32 inside the limit frame 31 can be realized. When the extraction plate 32 slides inside the limit frame 31, relative movement will occur between the first placement hole 37 and the second placement hole 38. Then, the misalignment adjustment between the first placement hole 37 and the second placement hole 38 can be realized. The diamond-shaped pore formed between the first placement hole 37 and the second placement hole 38 will be adjusted as the extraction plate 32 moves inside the limit miner. Place the test tube inside the first placement hole 37 and the second placement hole 38, which facilitates the stable storage of test tubes of different sizes and avoids the phenomenon of exosomes leaking outside the test tube when the test tube is skewed. By setting the rubber block 39 with a spherical structure, the stability of storing the test tube is further improved. By setting the adjustment device 3, the limiting of test tubes of different sizes is facilitated, and the phenomenon of shaking and skewing when placing test tubes of different sizes inside the placement hole is avoided, which improves the service performance of the exosome storage device to a certain extent.

[0037] Before sliding the drawer frame 2 into the inside of the storage box 1, first pull the retaining frame 44. After lifting the retaining frame 44 to an appropriate height, slide the support frame 43 inside the retaining frame 44 and support the support frame 43 on the surface of the rectangular plate 41. At this time, the temporary support for the lifted retaining frame 44 can be achieved. At this time, the drawer frame 2 can be flexibly pulled inside the storage box 1. After the drawer frame 2 is stored inside the storage box 1, slide out the support frame 43 above the rectangular plate 41. At this time, the retaining frame 44 will be blocked outside the drawer frame 2 under the elastic force of the spring 45 on the rectangular plate 41, thereby enabling the buckling of the drawer frame 2 inside the storage box 1. By setting the buckle structure 4, the quick buckling of the drawer frame 2 sliding into the inside of the storage box 1 is facilitated, and the phenomenon of the drawer frame 2 slipping out easily from the inside of the storage box 1 is avoided.
