Description

Technical Field

[0001] This utility model relates to the field of reagent kit technology, specifically an automatic shaken reagent kit. Background Technology

[0002] A reagent kit is a box used to hold chemical reagents for detecting chemical components, drug residues, virus types, etc. During reagent testing, kits are typically used to collect the reagents uniformly. When detecting biochemicals, the liquid components in the reagent tubes need to be thoroughly mixed to ensure the accuracy of the test results; and often, multiple samples need to undergo the same pretreatment and mixing operations simultaneously.

[0003] Existing reagent kits often suffer from significant localized differences in component concentration due to insufficient mixing. Traditional manual shaking is time-consuming and labor-intensive, and prone to fatigue leading to inconsistent operation. Furthermore, it's difficult for each person to maintain consistent pressure, frequency, and method when manually shaking reagent tubes, resulting in varying degrees of mixing in each tube and substantial human error, leading to inaccurate test results. Therefore, this application proposes an automatically mixing reagent kit that simplifies manual operation while ensuring thorough mixing of the liquid within the reagent tubes. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automatically shaken reagent kit to solve the problems of insufficient mixing and excessive local component concentration differences in existing reagent kits; and the time-consuming, laborious, and uneven shaking of traditional manual shaking, thereby improving detection efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic shaking reagent kit, comprising a reagent kit housing, a power mechanism installed on the bottom surface of the reagent kit housing, the power mechanism driving the shaking mechanism to rotate, a reagent tube fixing mechanism connected above the shaking mechanism, and the reagent tube fixing mechanism moving up and down along a first guide rod;

[0006] The power mechanism includes a motor, which is fixed to the bottom of the reagent kit box via a motor frame; the output shaft of the motor passes through the mounting hole of the motor frame and a drive gear is fixedly mounted at the output end, and the drive gear is meshed with a driven gear;

[0007] The shaking mechanism includes a rotating rod, both ends of which are mounted in the reagent kit housing via bearings. A driven gear is installed in the middle of the rotating rod, and a crankshaft is provided on the rotating rod. The crankshaft is connected to a connecting rod, which is hinged to the bottom surface of the reagent tube fixing mechanism.

[0008] As a further technical solution, the reagent tube fixing mechanism includes an inner box, with the upper end of the connecting rod hinged to the bottom surface of the inner box; a fixing plate is fixed to the upper end of the inner box; a lifting screw is installed in the middle of the inner box, with a handwheel installed after the upper end of the lifting screw passes through the fixing plate, and the lower end of the lifting screw is installed on the bottom surface of the inner box via a bearing; second guide rods are provided on both sides of the inner box; a lifting placement plate is installed in the inner box, with the lifting screw passing through the middle of the lifting placement plate via a threaded connection, and the lifting placement plate moving up and down along the second guide rods on both sides; placement slots are evenly distributed on the lifting placement plate, and placement holes corresponding to the placement slots are opened on the fixing plate, with a fixing sleeve provided at each placement hole on the fixing plate; a limiting cover plate is installed on the fixing plate, and a buffer plug located inside the fixing sleeve is provided on the bottom surface of the limiting cover plate.

[0009] As a further technical solution, a buffer pad is provided on the inner wall of the placement hole; a buffer pad is also provided inside the placement groove of the lifting placement plate.

[0010] As a further technical solution, the limiting cover is fixedly mounted on the fixed plate by screws.

[0011] As a further technical solution, four first guide rods are installed at the four corners inside the reagent kit box, and first guide holes are opened at the four corners of the inner box, through which the first guide rods pass.

[0012] As a further technical solution, the reagent kit box is provided with a box cover, and the box cover is provided with latches on both sides, which realize the detachable fixation to the reagent kit box.

[0013] As a further technical solution, a handle is fixedly installed on the box cover.

[0014] The working principle of this utility model is as follows:

[0015] When this invention is in operation, the motor's output shaft drives the driving gear to rotate, which in turn drives the rotating rod to rotate via the driven gear. The rotating rod then drives the crankshaft to rotate, causing the connecting rod to slide the inner casing up and down along the first guide rod. The liquid inside the reagent tube forms a tumbling convection current during this reciprocating motion, ensuring that liquids of different densities and compositions come into full contact and achieve a more uniform mixture.

[0016] When multiple samples need to be pretreated and mixed in the same way, different reagent tubes can be placed into the inner chamber and shaken up and down at the same time to process multiple samples or reagent combinations at one time.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses the up-and-down movement of the inner chamber to create a turbulent convection flow of liquid inside the tube, which fully mixes liquids of different densities and compositions, resulting in a more uniform mixing effect and effectively avoiding excessive local differences in component concentration caused by insufficient mixing.

[0019] 2. This utility model has multiple reagent tube slots, which can perform the same pretreatment and mixing operations on multiple samples in one go, saving the time of processing each reagent tube individually and improving the overall detection efficiency.

[0020] 3. This utility model can raise the reagent tubes to an easily accessible position by setting a lifting placement plate. Operators can directly take the required reagent tubes from the top of the reagent kit, which greatly improves the convenience of operation, saves operation time, and makes the detection process smoother.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Reference Figure 1-3The reagent kit shown includes a reagent kit housing 1. A power mechanism is installed on the bottom surface of the reagent kit housing 1. The power mechanism drives the shaking mechanism to rotate. A reagent tube fixing mechanism is connected above the shaking mechanism. The reagent tube fixing mechanism moves up and down along the first guide rod 11.

[0028] like Figure 3 As shown, the reagent kit box 1 is provided with a box cover 12, a handle 122 is fixedly installed on the box cover 12, and latches 121 are provided on both sides of the box cover 12, which realize the detachable fixation to the reagent kit box 1.

[0029] 1. Power mechanism

[0030] The power mechanism includes a motor 2, which is fixed to the bottom of the reagent kit box 1 via a motor frame 21. The output shaft of the motor 2 passes through the mounting hole of the motor frame 21 and a drive gear 22 is fixedly mounted at the output end. The drive gear 22 is meshed with a driven gear 23.

[0031] 2. Shaking mechanism

[0032] The shaking mechanism includes a rotating rod 3, which is mounted inside the reagent kit box 1 at both ends via bearings. A driven gear 23 is installed in the middle of the rotating rod 3. A crankshaft 4 is provided on the rotating rod 3, and the crankshaft 4 is connected to a connecting rod 5. The connecting rod 5 is hinged to the bottom surface of the reagent tube fixing mechanism.

[0033] 3. Reagent tube fixing mechanism

[0034] The reagent tube fixing mechanism includes an inner box 6, with the upper end of the connecting rod 5 hinged to the connecting lug 61 on the bottom surface of the inner box 6; a fixing plate 8 is fixed to the upper end of the inner box 6. A lifting screw 63 is installed in the middle of the inner box 6, with a handwheel 631 installed after the upper end of the lifting screw 63 passes through the fixing plate 8, and the lower end of the lifting screw 63 is installed on the bottom surface of the inner box 6 via a bearing. Second guide rods 62 are provided on both sides of the inner box 6; a lifting placement plate 7 is installed inside the inner box 6, with the lifting screw 63 threaded through the middle of the lifting placement plate 7, allowing the lifting placement plate 7 to move up and down along the second guide rods 62 on both sides. Placement slots 71 are evenly distributed on the lifting placement plate 7, and placement holes 81 corresponding to the placement slots 71 are opened on the fixing plate 8, with a fixing sleeve 82 located at each placement hole 81 on the fixing plate 8. A limiting cover plate 9 is installed on the fixing plate 8, with a buffer plug 91 located inside the fixing sleeve 82 on the bottom surface of the limiting cover plate 9.

[0035] When retrieving the reagent tube, remove the limiting cover 9 from the fixing plate 8, then turn the handwheel 631 to rotate the lifting screw 63, causing the lifting placement plate 7 to move along the second guide rod 62. As the lifting placement plate 7 moves upward, the reagent tube 10 rises to a position that is easy to retrieve. The operator can easily retrieve the required reagent tube 10 directly from the top of the reagent kit, greatly improving the convenience of operation and increasing the detection efficiency.

[0036] Preferably, a buffer pad is provided on the inner wall of the placement hole 81; a buffer pad is also provided inside the placement slot 71 of the lifting placement plate 7. When the reagent kit is subjected to slight vibration, collision, or is accidentally dropped during handling, the buffer pad can absorb most of the energy, reduce the impact of the impact on the reagent tube, reduce the risk of test tube breakage, avoid reagent leakage causing waste and contamination, and also ensure the safety of the operator.

[0037] Preferably, the limiting cover 9 is fixedly mounted on the fixing plate 8 by screws 92. The buffer plug 91 on the limiting cover 9 abuts against the reagent tube 10 inside the fixing sleeve 82. When the screws 92 are tightened, the position of the limiting cover 9 is fixed, ensuring that the stroke and amplitude of each reagent tube 10 are consistent during the up-and-down movement, thus achieving precise limiting of the reagent tube 10. During the up-and-down movement of the reagent tube 10, the limiting cover 9 restricts the vertical movement of the reagent tube 10, preventing the reagent tube 10 from colliding, and allowing the reagent inside the reagent tube 10 to move within a relatively controllable range, protecting the reagent tube 10 from damage.

[0038] like Figure 1-2 As shown, four first guide rods 11 are installed at the four corners inside the reagent kit box 1. First guide holes 64 are opened at the four corners of the inner box 6. The first guide rods 11 pass through the first guide holes 64, restricting the inner box 6 from sliding up and down along the first guide rods 11.

[0039] The working process and advantages of this utility model:

[0040] Turn on the control switch to start the motor 2. The output shaft of the motor 2 drives the drive gear 22 to rotate. The drive gear 22 drives the rotating rod 3 to rotate through the driven gear 23. The rotating rod 3 then drives the crankshaft 4 to rotate, causing the connecting rod 5 to drive the inner housing 6 to slide up and down along the first guide rod 11.

[0041] The liquid inside the reagent tube 10 forms a rolling convection as it moves up and down, allowing liquids of different densities and compositions to come into full contact and achieve a more uniform mixture, thus avoiding the problem of excessive local differences in component concentration caused by uneven mixing.

[0042] When multiple samples need to undergo the same pretreatment and mixing operations, different reagent tubes can be placed into the inner chamber and shaken up and down simultaneously to process multiple samples or reagent combinations at once, saving the time of individual processing and improving the overall detection efficiency.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
