Description

Technical Field

[0001] The utility model relates to the technical field of reagent kits, in particular to a magnetic bead liquid storage reagent kit. Background Art

[0002] Bionanomagnetic beads are magnetic nanoparticles synthesized by microorganisms. They are natural biomagnetic nanomaterials with some advantages that artificially synthesized magnetic beads cannot match. By using genetic engineering technology or combining chemical modification technology, special biological functional molecules can be displayed on the surface of bionanomagnetic beads in a directional manner, or coated with other substances such as silane substances, so that bionanomagnetic beads can be used for the purification and extraction of common nucleic acids and specific nucleic acid molecules. The current magnetic bead liquid storage kit can only take out the reagent tubes from the kit one by one after opening it, and it is not possible to take out the actual tray containing the reagent tubes from the kit at one time, which is a waste of time.

[0003] For example, a Chinese patent with a publication (announcement) number of CN219278147U discloses a whole blood nucleic acid extraction kit based on nanomagnetic beads, including an outer box, a cavity is opened on one side of the outer box, a reagent box is slidably installed inside the cavity, a knob is rotatably installed on the other side of the outer box, a threaded rod is fixedly installed on one end of the knob, a threaded hole matching the threaded rod is opened at the bottom of the reagent box, the threaded rod passes through the outer box and is threadedly connected in the threaded hole, a cavity is opened on one side of the outer box, a reagent box is slidably installed inside the cavity, the threaded rod passes through the outer box and is threadedly connected in the threaded hole opened at the bottom of the reagent box, and one end of the threaded rod is fixedly installed on the knob on the other side of the reagent box, and the threaded rod is driven to rotate by rotating the knob, so that the reagent box can be pushed out or retracted into the outer box.

[0004] The reagent kit involved in the above patent requires that the reagent tubes in the reagent kit be taken out one by one after the reagent kit is pulled out from the outer box, and all the reagent tubes cannot be taken out directly at one time. The removal is more troublesome and wastes a lot of time. Therefore, we need to propose a magnetic bead liquid storage reagent kit. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 5 The utility model provides a magnetic bead liquid storage kit, including an outer shell 1, an inner box 2 is slidably connected to the inner cavity of the outer shell 1, a limiting component is arranged between the bottom of the inner box 2 and the bottom of the inner cavity of the outer shell 1, the limiting component includes a T-shaped limiting rod 7 fixedly installed on both sides of the bottom of the inner box 2, a limiting groove 8 is provided at the bottom of the inner cavity of the outer shell 1 and at a position corresponding to the T-shaped limiting rod 7, and the surface of the T-shaped limiting rod 7 is slidably connected to the inner wall of the limiting groove 8.

[0023] In this embodiment, a handle is installed on the top of the outer shell 1, which can facilitate the user to move and carry the device, and the inner box 2 is slidably installed in the inner cavity of the outer shell 1 through a limiting assembly. When the reagent tube 22 inside the inner box 2 needs to be taken out, the user can pull the inner box 2 out of the inner cavity of the outer shell 1. The movement of the inner box 2 will drive the T-shaped limiting rod 7 to slide in the inner cavity of the limiting groove 8. The coordinated use of the T-shaped limiting rod 7 and the limiting groove 8 can prevent the inner box 2 from being disconnected from the outer shell 1.

[0024] Preferably, the inner cavity of the inner box 2 is provided with a liftable lifting plate 3, and a lifting assembly is provided at the bottom of the lifting plate 3. The lifting assembly includes lifting blocks 9 fixedly installed at the four corners of the bottom of the lifting plate 3, and an oblique cut 10 is provided at one corner of the bottom of the lifting block 9. The bottom of the lifting plate 3 and the inner side of the four groups of lifting blocks 9 are provided with a driving assembly for driving the lifting blocks 9 to lift and move. The driving assembly includes a driving screw rod 11 rotatably installed on the back side of the inner cavity of the inner box 2, and the surface of the driving screw rod 11 is provided with two groups of external threads 12 in opposite directions. A rotating rod 13 is fixedly installed at one end of the driving screw rod 11, and the end of the rotating rod 13 away from the driving screw rod 11 passes through the inner cavity 11 in sequence. The box 2 and the shell 1 are fixedly connected with a knob 14 extending to the outside of the shell 1, and two groups of sliding sleeves 15 are matched with each other on the surface of the driving screw 11. Connecting rods 16 are fixedly installed on both sides of the sliding sleeve 15, and a driving block 17 is fixedly installed on the end of the connecting rod 16 away from the sliding sleeve 15. A round chamfer 18 is provided at a corner corresponding to the driving block 17 and the oblique cut 10. A reagent tray 4 is provided on the top of the lifting plate 3, and a plurality of positioning holes 21 are opened on the top of the reagent tray 4.

Drawing grooves 5 are opened on the front and rear sides of the reagent tray 4, and operating grooves 6 corresponding to the drawing grooves 5 are opened on the front and rear sides of the inner box 2.

[0025] After the inner box 2 is pulled out from the outer shell 1, the user can rotate the knob 14. The rotation of the knob 14 will drive the driving screw 11 to rotate through the rotating rod 13. Since the surface of the driving screw 11 is provided with two sets of external threads 12 in opposite directions, when it rotates, it will drive the two sets of sliding sleeves 15 to move in opposite directions, and then drive the driving block 17 to move through the connecting rod 16. The rounded chamfer 18 of the driving block 17 will abut against the bevel cut 10 of the lifting block 9, so that the lifting plate 3 is lifted through the lifting block 9, and then the reagent tray 4 is lifted. At this time, the pull groove 5 on the surface of the reagent tray 4 will move to the operating groove 6, and the user can pull the pull groove 5 to take out the reagent tray 4 and the reagent tube 22 on the top of it at one time.

[0026] It is worth mentioning that a rotating hole 19 is provided on the surface of the inner box 2 and located at a corresponding position of the rotating rod 13. The surface of the rotating rod 13 is rotatably connected to the inner wall of the rotating hole 19. The setting of the rotating hole 19 can provide a rotating space for the rotating rod 13; a groove 20 is provided on the surface of the outer shell 1 and located at a corresponding position of the rotating rod 13. The surface of the rotating rod 13 is slidably connected to the inner wall of the groove 20. The setting of the groove 20 can provide a moving space for the rotating rod 13. When the inner box 2 is pulled out to the outside, the movement of the inner box 2 will drive the rotating rod 13 to slide in the inner cavity of the groove 20.
