Description

Technical Field

[0001] The utility model relates to the field of reagent preparation, in particular to a reagent preparation device. Background Art

[0002] Biological reagents refer to biological materials or organic compounds related to life science research, as well as reagents used in clinical diagnosis and medical research. Due to the broad scope and rapid development of life science, such reagents are of various types and complex in nature.

[0003] The existing patent publication number CN218485777U proposes a reagent preparation device, which realizes the synchronous shaking operation of multiple reagent tubes by setting components such as a turntable and a rack, thereby achieving the purpose of increasing the working rate. However, the above device has certain defects: for example, when shaking, it is necessary to set components such as a top plate, a sealing plate, and a telescopic cylinder to limit the height direction of the reagent tube to improve the stability of the reagent tube and prevent the liquid in the reagent tube from spilling. Therefore, when taking it later, it is also necessary to raise the sealing plate to form a sufficient gap between it and the reagent tube, so that the reagent tube can be taken after shaking, which will correspondingly extend the preparation time of the reagent tube.

[0004] Therefore, a reagent preparation device is needed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a reagent mixing device, so as to quickly take out the reagent tube after being shaken, thereby shortening the time required for mixing the reagent tube.

[0006] In order to solve the above technical problems, the utility model provides a reagent preparation device, including a base plate, an arc-shaped limit plate, a turntable, a rotating placement cylinder and a linkage assembly;

[0007] The arc-shaped limiting plate is fixedly mounted on the base plate and is used to limit the reagent tube in the height direction;

[0008] The turntable is rotatably mounted on the base plate;

[0009] The rotating placement cylinder is rotatably mounted on the edge of the upper surface of the rotating disk, and when driven by the rotating disk, it can be rotated to the bottom of the arc-shaped limiting plate or exposed to the outside of the arc-shaped limiting plate;

[0010] The linkage assembly is arranged between the outer wall of the rotating placement cylinder and the inner wall of the arc-shaped limiting plate;

[0011] When the rotating placement cylinder is rotated to the bottom of the arc-shaped limiting plate by the driving force of the turntable and continues to rotate with the turntable, the linkage assembly can pull the rotating placement cylinder to rotate.

[0012] Further, the linkage assembly includes an arc-shaped tooth block and a fixed tooth ring;

[0013] The arc-shaped tooth block is fixedly mounted on the side wall of the arc-shaped limiting plate close to the rotating disk;

[0014] The fixed tooth ring is fixedly mounted on the outer wall of the rotating placement cylinder and meshes with the arc-shaped tooth block.

[0015] Furthermore, the arc-shaped gear block and the turntable share a common rotation axis.

[0016] Furthermore, the inner wall of the rotating placement cylinder is provided with a plurality of limiting members for limiting the position of the reagent tube, so that the rotating placement cylinder can remain relatively fixed with the reagent tube.

[0017] Furthermore, the limiting member includes an arc-shaped ring and an elastic ball;

[0018] The arc-shaped ring is arranged on the inner wall of the rotating placement tube through an elastic telescopic rod, and can move toward the axial center direction of the rotating placement tube;

[0019] The elastic balls are fixedly mounted on the two ends of the arc-shaped ring to squeeze and limit the reagent tube.

[0020] Furthermore, the arc-shaped limiting plate has a protrusion extending toward the rotating disk on one side close to the rotating disk;

[0021] The lower surface of the protrusion has a connected arc track.

[0022] Furthermore, the arc track is the same as the rotation track of the reagent tube.

[0023] Furthermore, the arc track is configured as a T-shaped structure.

[0024] Furthermore, the rotating placement cylinders are provided in plurality and are arranged equidistantly in a ring shape.

[0025] Furthermore, a driving motor connected to the turntable is disposed in the substrate.

[0026] Compared with the prior art, the utility model has at least the following beneficial effects:

[0027] By setting a linkage component, when the rotating placement cylinder carrying the reagent tube is driven by the turntable to rotate to the bottom of the arc-shaped limit plate, it can independently drive the reagent tube to rotate for shaking operation, and because the arc-shaped limit plate can limit the reagent tube in the height direction, the stability of the reagent tube during the shaking process can be guaranteed. Moreover, when the reagent tube shaking operation is completed, the reagent tube can be separated from the arc-shaped limit plate, that is, exposed to the outside of the arc-shaped limit plate, and then the operator can directly take the shaken reagent tube at this time, so as to effectively shorten the time required for the preparation of the reagent tube.

[0031] The reagent preparation device of the present invention will be described in more detail below in conjunction with the schematic diagram, wherein a preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art can modify the present invention described herein, and still achieve the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the present invention.

[0032] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0033] like Figure 1 and Figure 2 As shown, an embodiment of the utility model proposes a reagent preparation device, including a base plate 1, an arc-shaped limiting plate 2, a turntable 3, a rotating placement cylinder 4 and a linkage component 5.

[0034] The arc-shaped limiting plate 2 is fixedly mounted on the base plate 1 and is used to limit the reagent tube in the height direction, so that when the subsequent reagent tube is rotated and shaken, the reagent tube can remain in a stable state without spilling.

[0035] The turntable 3 is rotatably mounted on the base plate 1 and is used to drive the rotating placement cylinder 4 to rotate to the bottom of the arc-shaped limiting plate 2, so that the rotating placement cylinder 4 can rotate and shake evenly.

[0036] The rotating placement cylinder 4 is rotatably mounted on the edge of the upper surface of the turntable 3 , and when driven by the rotation of the turntable 3 , it can rotate to the bottom of the arc-shaped limiting plate 2 or be exposed to the outside of the arc-shaped limiting plate 2 .

[0037] Therefore, when the rotating placement cylinder 4 completes the rotation and shaking under the arc-shaped limiting plate 2 and is exposed to the outside of the arc-shaped limiting plate 2, the operator can directly take the reagent tube. Therefore, compared with the existing technology, the operation step of raising the sealing plate can be effectively saved, thereby shortening the time for preparing the reagent tube.

[0038] The linkage assembly 5 is arranged between the outer wall of the rotating placement cylinder 4 and the inner wall of the arc-shaped limiting plate 2 .

[0039] When the rotating placement cylinder 4 is driven by the turntable 3 to rotate to the bottom of the arc-shaped limit plate 2 and continues to rotate with the turntable 3, the linkage assembly 5 can pull the rotating placement cylinder 4 to rotate, that is, drive the reagent tube to rotate, and complete the shaking function.

[0040] To summarize, the present device is provided with a linkage assembly 5, so that when the rotating placement cylinder 4 carrying the reagent tube is rotated to the bottom of the arc-shaped limit plate 2 by the driving force of the turntable 3, it can autonomously drive the reagent tube to rotate to perform a shaking operation, and since the arc-shaped limit plate 2 can limit the reagent tube in the height direction, the stability of the reagent tube during the shaking process can be guaranteed, and after the reagent tube shaking operation is completed, the reagent tube can be separated from the arc-shaped limit plate 2, that is, exposed outside the arc-shaped limit plate 2, and then the operator can directly take the shaken reagent tube at this time, so as to effectively shorten the time required for the preparation of the reagent tube.

[0041] In this embodiment, a specific linkage assembly 5 is provided so that the rotating placement cylinder 4 can rotate on its own when the turntable 3 rotates under the arc-shaped limiting plate 2 to complete the shaking operation of the reagent tube.

[0042] Specifically, the linkage assembly 5 includes an arc-shaped tooth block 51 and a fixed tooth ring 52 .

[0043] The arc-shaped tooth block 51 is fixedly mounted on the side wall of the arc-shaped limiting plate 2 close to the turntable 3, and the fixed tooth ring 52 is fixedly mounted on the outer wall of the rotating placement tube 4 and meshes with the arc-shaped tooth block 51. When the fixed tooth ring 52 abuts against the arc-shaped tooth block 51, the rotating placement tube 4 will rotate by itself under the influence of the meshing action and the rotational power of the turntable 3, thereby achieving even shaking of the reagent tube.

[0044] It should be particularly noted that the arc-shaped tooth block 51 and the turntable 3 share a common rotation axis to ensure that when the turntable 3 rotates, the fixed tooth ring 52 will not interfere with the arc-shaped tooth block 51 .

[0045] In a further embodiment, the inner wall of the rotating placement cylinder 4 is provided with a plurality of limiting members 6 for limiting the position of the reagent tube, so that the rotating placement cylinder 4 can remain relatively fixed with the reagent tube, thereby improving the stability of the reagent tube placement.

[0046] Specifically, the limiting member 6 includes an arc ring 61 and an elastic ball 62 .

[0047] The arc ring 61 is arranged on the inner wall of the rotating placement tube 4 through an elastic telescopic rod, and can move toward the axial center direction of the rotating placement tube 4.

[0048] The elastic balls 62 are fixedly mounted on both ends of the arc ring 61 to squeeze and limit the reagent tube.

[0049] In addition, the arc-shaped limiting plate 2 has a protrusion 21 extending toward the rotating disk 3 on one side thereof close to the rotating disk 3 .

[0050] The lower surface of the protrusion 21 has a connected arc track 211, which is used to limit and seal the reagent tube in the height direction to prevent the reagent tube from being spilled during the shaking process.

[0051] It should be particularly noted that the reagent tube can rotate within the arc track 211, that is, the inner diameter of the arc track 211 should be slightly larger than the outer diameter of the end of the reagent tube to ensure that there is no interference with the rotation of the reagent tube.

[0052] It should also be noted that the arc track 211 is the same as the rotation track of the reagent tube.

[0053] In addition, the arc track 211 is configured as a T-shaped structure.

[0054] In other embodiments, in order to be able to shake multiple reagent tubes, multiple rotating placement cylinders 4 are provided and are arranged equidistantly in a ring shape.

[0055] In addition, a driving motor connected to the turntable 3 is disposed in the substrate 1 .

[0056] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
