Description

Technical Field

[0001] This utility model relates to the field of reagent kit technology, and in particular to a universal sequencing reaction reagent kit. Background Technology

[0002] A universal sequencing reaction kit is a pre-made kit for DNA sequencing experiments. The kit is used to store the reagent tubes required for DNA sequencing reactions in order to reduce the probability of damage to the reagent tubes during storage.

[0003] Patent specification CN221115008U discloses a universal sequencing reaction kit, comprising: a housing fixedly connected to the upper end face of a base; a top cover hinged to the upper end face of the housing; two stops, both fixedly connected to the outer side of the housing; a handle hinged to the outer side of the housing; a reagent rack slidably connected to the inner side of the housing; two sets of fixing plates, both fixedly connected to the inner side of the base; two sets of fixing blocks, both fixedly connected to the inner side of the base; and two sets of suction cups, both fixedly connected to the lower end face of the base. This design allows for adjustment of the adjustment blocks, reducing usage costs.

[0004] However, in implementing the relevant technology, the following problems were found with the aforementioned universal sequencing reaction kit: The device's adjustment blocks can move horizontally, allowing the spacing between the adjustment blocks to be adjusted, thus enabling the positioning of reagent tubes of different sizes. However, the adjustment blocks are inconvenient to disassemble and assemble. When storing multiple large-sized reagent tubes, the spacing between some adjustment blocks is too large, occupying a large space, while the spacing between some adjustment blocks is too small to store reagent tubes. These adjustment blocks occupy part of the storage space, increasing the waste of reagent rack space. When storing multiple small-sized reagent tubes, the spacing between the adjustment blocks is too small, leaving some space in the reagent rack without adjustment blocks, wasting the storage space of the reagent rack, reducing space utilization, and thus reducing the storage efficiency of the device. In view of this, a universal sequencing reaction kit is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a universal sequencing reaction kit.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a universal sequencing reaction reagent kit, comprising a protective box, a storage box fixedly disposed inside the protective box, a plurality of placement slots being provided at the top of the storage box, a plurality of fixing plates being provided at the top of the storage box, two positioning shafts being fixedly disposed at the top of each of the fixing plates, a positioning disk being fixedly disposed at the top of each of the positioning shafts, a connecting spring being fixedly disposed at the bottom of each of the positioning disks, a movable plate being provided at the top of each of the fixing plates, two limiting shafts being fixedly disposed at the bottom of each of the movable plates, a pull ring being fixedly disposed at the top of each of the movable plates, and two sliders being fixedly disposed at the bottom of each of the fixing plates, two sliding grooves being provided at the top of the storage box, the interiors of the two sliding grooves respectively fitting against the sides of the plurality of sliders, four inlet / outlet slots being provided at the top of the storage box, and a plurality of placement blocks being fixedly disposed at the bottom of each of the fixing plates, the sides of the plurality of placement blocks respectively fitting against the interiors of the plurality of placement slots.

[0007] As a further description of the above technical solution: the interior of the several movable plates is slidably connected to the sides of several positioning shafts, and the top of the several movable plates is fixedly connected to the bottom of several connecting springs, so that the movable plates can be used to fix the limiting shafts.

[0008] As a further description of the above technical solution: the top of the storage box is provided with several limiting holes, and the sides of several limiting shafts respectively fit into the interior of the corresponding several limiting holes, so that the storage box can easily place reagent tubes.

[0009] As a further description of the above technical solution: each of the aforementioned fixing plates has two fixing holes inside, and the interior of each of the aforementioned fixing holes is respectively in contact with the side of a plurality of limiting shafts, so that the fixing plates can easily fix the placement block.

[0010] As a further description of the above technical solution: the bottom of the protective box is provided with a base plate, and the top of the base plate is fixedly provided with a connecting box, and the base plate facilitates the fixing of the connecting box.

[0011] As a further description of the above technical solution: the top of the connecting box is provided with a connecting groove, and two connecting blocks are slidably connected inside the connecting groove. The top of each of the two connecting blocks is hinged with a support rod, and the top of each of the two support rods is hinged to the bottom of the protective box. The connecting blocks facilitate the connection of the support rods.

[0012] As a further description of the above technical solution: the internal part of the connecting box is rotatably connected to a bidirectional threaded rod, the side of the bidirectional threaded rod is respectively threadedly connected to the internal parts of two connecting blocks, and a handle is fixedly provided at one end of the bidirectional threaded rod, which facilitates the rotation of the bidirectional threaded rod.

[0013] As a further description of the above technical solution: four sleeves are fixedly provided at the top of the base plate, and each of the four sleeves is provided with a fixing rod inside. The top of each of the four fixing rods is fixedly connected to the bottom of the protective box. The fixing rods and sleeves facilitate the improvement of the stability of the storage box when it is moved.

[0014] This utility model has the following beneficial effects:

[0015] This invention relates to a universal sequencing reaction kit. Through its design and coordination, reagent tubes are stored in the gaps between the placement blocks. Moving the handle upwards disengages the limiting shaft from the storage box, allowing the slider, fixing plate, and placement blocks to move left and right without being restrained. This adjusts the spacing between the placement blocks within the same slot, enabling the placement blocks to restrain reagent tubes of different sizes. If multiple large-sized reagent tubes are stored, resulting in a large gap between the placement blocks and rendering some fixing plates and placement blocks unusable, the excess fixing plates, placement blocks, and slider are moved to the sides of the storage box, allowing the slider to enter the inlet / outlet slot within the storage box. Moving the fixing plate upwards then moves the placement blocks and slider upwards, disengaging the slider from the inlet / outlet slot, thus removing the excess fixing plates and placement blocks. This frees up space within the storage box for additional reagent tubes. If multiple small-sized reagent tubes are stored, resulting in a small gap between the placement blocks and causing internal issues within the storage box... When the designated areas are cleared, the additional fixing plate and placement block are moved down, allowing the slider at the bottom of the fixing plate to enter the inlet / outlet groove and the placement block to enter the placement groove. The fixing plate is then moved horizontally, causing the slider to move into the slide groove, thus limiting the slider, fixing plate, and placement block to only move left and right. After the fixing plate and placement block are moved to the designated position, the handle is released, and the connecting spring presses the movable plate, causing the movable plate and the limiting shaft to move down, allowing the limiting shaft to enter the corresponding limiting hole in the storage box. This limits the slider, fixing plate, and placement block to be unable to move, and the empty space in the storage box is utilized to store more reagent tubes. This makes it easy to adjust the spacing between the placement blocks, allowing the placement blocks to limit reagent tubes of different sizes. The device also allows for quick assembly and disassembly of placement blocks, enabling the quick removal of extra placement blocks and the rapid addition of placement blocks to the empty space in the storage box, reducing space waste and improving the storage efficiency of the device.

[0016] This invention relates to a universal sequencing reaction reagent kit. Through its design, when the storage box is high, turning the handle moves the storage box downwards, and the sleeve and fixing rod improve the stability of the storage box during movement. When the storage box is low, reversing the handle moves the storage box upwards, making the height of the storage box easy to adjust. This allows the device to be easily adjusted according to the height of the user, making it easier for people of different heights to access the reagent tubes, thereby improving the ease of use of the device.

[0024] Reference Figures 1-5 This utility model provides a universal sequencing reaction reagent kit, comprising a protective box 1, inside which a storage box 2 is fixedly installed. The top of the storage box 2 has several placement slots, and the top of the storage box 2 has several fixing plates 3. Each fixing plate 3 has two positioning shafts 4 fixedly installed at its top, which facilitates the positioning of a slider 10. Each positioning shaft 4 has a positioning disc 5 fixedly installed at its top, which facilitates the fixing of a connecting spring 6. Each positioning disc 5 has a connecting spring 6 fixedly installed at its bottom, which facilitates the compression of a movable plate 7. The fixing plates... Each of the three fixed plates 3 has a movable plate 7 at its top. Each of the movable plates 7 has two limiting shafts 8 fixed at its bottom. Each of the movable plates 7 has a pull ring 9 fixed at its top. The pull ring 9 facilitates the movement of the movable plates 7. Each of the fixed plates 3 has two sliders 10 fixed at its bottom. Each of the storage boxes 2 has two sliding grooves at its top. The interior of each sliding groove is in contact with the sides of each slider 10. Each of the storage boxes 2 has four inlet and outlet slots at its top. Each of the fixed plates 3 has several placement blocks 11 fixed at its bottom. The sides of each placement block 11 are in contact with the interior of each placement slot.

[0025] As a further implementation of the above technical solution: the interior of several movable plates 7 is slidably connected to the sides of several positioning shafts 4, and the top of several movable plates 7 is fixedly connected to the bottom of several connecting springs 6, so that the movable plates 7 can be used to fix the limiting shafts 8.

[0026] As a further implementation of the above technical solution: the top of the storage box 2 is provided with several limiting holes, and the sides of several limiting shafts 8 respectively fit into the interior of the corresponding several limiting holes, so that the storage box 2 can be used to place reagent tubes.

[0027] As a further implementation of the above technical solution: each of the fixing plates 3 has two fixing holes inside, and the inside of the fixing holes is respectively in contact with the side of the limiting shafts 8, so that the fixing plates 3 can be used to fix the block 11.

[0028] In practice: reagent tubes are stored through the gaps between the placement blocks 11. By moving the handle 17 upward, the movable plate 7 and the limiting shaft 8 are moved upward. At this time, the limiting shaft 8 disengages from the storage box 2, causing the slider 10 to lose its limit and move left and right. This allows the fixing plate 3 and the placement blocks 11 to move left and right. Moving the fixing plate 3 and the placement blocks 11 left and right allows the placement blocks 11 to move left and right, thus adjusting the spacing between the placement blocks 11 in the same placement slot. This allows the placement blocks 11 to limit reagent tubes of different sizes. If multiple large-sized reagent tubes are stored, resulting in a large spacing between the placement blocks 11, the solution will be correct. When some of the fixing plates 3 and placement blocks 11 become unusable, the excess fixing plates 3 and placement blocks 11 are moved to both sides of the storage box 2, thereby moving the corresponding sliders 10 to both sides of the sliding groove inside the storage box 2, so that the sliders 10 enter the inlet / outlet slots inside the storage box 2. At this time, the fixing plates 3 are moved upward, thereby moving the placement blocks 11 and sliders 10 upward, so that the sliders 10 disengage from the inlet / outlet slots and the placement blocks 11 disengage from the placement slots, thereby removing the excess fixing plates 3 and placement blocks 11. The space occupied by the excess placement blocks 11 in the storage box 2 is freed up, and additional reagent tubes can be stored. If multiple small-sized reagent tubes are stored, the space occupied by the excess placement blocks 11 can be used to store additional reagent tubes. The small spacing between blocks 11 causes some areas inside storage box 2 to be empty. When the additional fixing plate 3 and the placement block 11 are moved downwards, the slider 10 at the bottom of the fixing plate 3 enters the inlet / outlet groove, and the placement block 11 enters the placement groove. The fixing plate 3 is then moved horizontally, causing the slider 10 to move into the slide groove, thus limiting its movement. This limits the fixing plate 3 and the placement block 11 to only move left and right. After moving the fixing plate 3 and the placement block 11 to the designated position, the handle 17 is released. The connecting spring 6 then presses against the movable plate 7, causing the movable plate 7 and the limiting shaft 8 to move downwards, thus limiting the movement of the sliding block 10. The positioning shaft 8 enters the corresponding limiting hole in the storage box 2, thereby limiting the slider 10 and preventing it from moving. This limits the fixing plate 3 and the placement block 11, preventing them from moving. At this time, the empty space in the storage box 2 is utilized, allowing more reagent tubes to be stored. This makes it easy to adjust the spacing between the placement blocks 11, allowing the placement blocks 11 to limit reagent tubes of different sizes. Furthermore, the device allows for quick assembly and disassembly of the placement blocks 11, enabling the quick removal of any extra placement blocks 11. The empty space in the storage box 2 can then be quickly filled with placement blocks 11, reducing space waste and improving the storage efficiency of the device.

[0029] As a further implementation of the above technical solution: the bottom of the protective box 1 is provided with a base plate 12, and the top of the base plate 12 is fixedly provided with a connecting box 13, so that the base plate 12 can be used to fix the connecting box 13.

[0030] As a further implementation of the above technical solution: the top of the connecting box 13 is provided with a connecting groove, and two connecting blocks 14 are slidably connected inside the connecting groove. The top of each of the two connecting blocks 14 is hinged with a support rod 15, and the top of each of the two support rods 15 is hinged to the bottom of the protective box 1. The connecting blocks 14 facilitate the connection of the support rods 15.

[0031] As a further implementation of the above technical solution: a bidirectional threaded rod 16 is rotatably connected inside the connecting box 13. The sides of the bidirectional threaded rod 16 are respectively threadedly connected to the inside of the two connecting blocks 14. A handle 17 is fixedly provided at one end of the bidirectional threaded rod 16, and the handle 17 facilitates the rotation of the bidirectional threaded rod 16.

[0032] As a further implementation of the above technical solution: four sleeves 18 are fixedly provided at the top of the base plate 12, and each of the four sleeves 18 is provided with a fixing rod 19 inside. The top of each of the four fixing rods 19 is fixedly connected to the bottom of the protective box 1. The fixing rods 19 and the sleeves 18 facilitate the improvement of the stability of the storage box 2 when it is moved.

[0033] In practical implementation: The existing device's storage box 2 has an inconvenient height adjustment. Due to varying heights, taller individuals need to bend over to retrieve reagent tubes, while shorter individuals need to raise their arms, increasing fatigue and reducing ease of use. In this new device, when the storage box 2 is high, rotating handle 17 rotates the bidirectional threaded rod 16, causing the two connecting blocks 14 to move away from each other, and consequently the two support rods 15 to move away from each other. The two support rods 15 then move the storage box 2 downwards, and the sleeve 18 and fixing rod 19 enhance the stability of the storage box 2 during movement. When the storage box 2 is low, reversing handle 17 reverses the bidirectional threaded rod 16, causing the two connecting blocks 14 to move closer together, and consequently the two support rods 15 to move closer together. The two support rods 15 then move the storage box 2 upwards, making the height of the storage box 2 easily adjustable. This allows the device to be adjusted according to the user's height, making it easier for people of different heights to retrieve reagent tubes, thus improving ease of use.

[0034] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
