Background
In Vitro Diagnostics (IVD) refers to the process of taking samples of blood, body fluids, tissues, etc. from a human body, and detecting and verifying the samples using In Vitro detection reagents, kits, calibrators, quality control substances, etc. to prevent, diagnose, treat, detect, later stage observe, evaluate health, predict genetic diseases, etc. for diseases.
The application of the reagent kit requires a motor to drive, so that the alignment and connection of an operation shaft in the reagent kit and a driving shaft of the motor are involved. The joints of the existing motor driving shaft and the operation shaft on the reagent box are respectively a U-shaped concave part and a convex part matched with the groove, and the connection is completed by inserting the convex part on the operation shaft into the concave part of the motor driving shaft. During production, it is often necessary for the operator to manually adjust the cartridge handling shaft and the motor drive shaft to a specific position in advance so that the projections and recesses are exactly matched in the circumferential direction so as to be axially accessible until fully engaged. However, since the above-mentioned adjustment process cannot be automatically implemented by a machine, the adjustment step is easily forgotten in the operation, or although the operation of the step is performed, there is an error in manual operation, which results in that in the production practice, the operation shaft of the reagent cartridge and the motor driving shaft move relatively at a certain angle in the alignment process, which causes the abrasion of the operation shaft on the reagent cartridge, the gap between the motor driving shaft and the operation shaft is too large due to the abrasion, and the IVD instrument generates powder, which may pollute the reagent cartridge and affect the beauty and performance of the product.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
The terms "mounted," "connected," and "coupled" are to be construed broadly and may, for example, be fixedly coupled, detachably coupled, or integrally coupled; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in further detail with reference to specific examples, but the embodiments of the present invention are not limited thereto.
As shown in fig. 1, an embodiment of the present invention provides a coupling structure applied to an in vitro diagnostic apparatus, and in particular, a structure capable of coupling a joint portion of an operation shaft of a cartridge with a joint portion of a driving shaft of a motor. As shown in fig. 3, a bevel concave portion and a circular convex portion are continuously provided on an outer peripheral edge portion of a joint portion of an operation shaft of the reagent kit, a bevel convex portion and a circular concave portion are continuously provided on an outer peripheral edge portion of a joint portion of a motor driving shaft, the bevel convex portion and the circular concave portion of the motor driving shaft and the bevel concave portion and the circular convex portion of the reagent kit operation shaft are correspondingly complementary structures, when the reagent kit operation shaft is inserted into the motor driving shaft, the circular convex portion of the reagent kit operation shaft contacts with the bevel convex portion of the motor driving shaft, and the circular convex portion generates a circumferential component force on the pressure of the bevel convex portion, so that the motor driving shaft automatically rotates until the joint portion thereof is aligned with the joint portion of the reagent kit operation shaft.
It should be noted that, in the above-described structure, it is not limited to which specific shaft the two complementary structures must be on as long as the structures of the joint portion of the operation shaft of the reagent cartridge and the joint portion of the drive shaft of the motor match each other. Namely, a bevel concave part and a circular convex part are continuously arranged on the first joint, a bevel convex part and a circular concave part are continuously arranged on the second joint, the first joint can be a joint part of an operation shaft of the reagent kit, and the second joint is correspondingly a joint part of a motor driving shaft; the first joint may also be a joint portion of a motor drive shaft and the second joint is correspondingly a joint portion of an operating shaft of the reagent cartridge.
In contrast to the prior art coupling structure shown in fig. 2, the joints of the motor drive shaft and the operation shaft on the reagent cartridge are respectively a U-shaped concave portion and a convex portion matching the concave groove, and the coupling is completed by inserting the convex portion on the operation shaft into the concave portion of the motor drive shaft. The connecting structure enables the reagent box operation shaft and the motor driving shaft to be aligned, and if the convex part of the operation shaft is not just inserted into the corresponding U-shaped concave part, relative movement of different angles is inevitable, so that the operation shaft on the reagent box is abraded.
The connection structure provided by the invention enables that: the end surface part of the reagent box operation shaft joint is not a plane any more, but is formed into a three-dimensional structure by arranging a plurality of inclined planes and convex parts; the end surface portion of the motor drive shaft joint is correspondingly provided with an inclined surface and a concave portion to match with the end surface portion of the reagent cartridge operation shaft joint.
When the reagent kit is inserted into the IVD instrument, the convex part on the operating shaft is contacted with the inclined convex part on the driving shaft of the motor, and the force of the contact of the convex part and the inclined surface is converted into a component force for rotating the driving shaft of the motor, so that the driving shaft of the motor automatically rotates to be aligned with the operating shaft of the reagent kit, the insertion in the axial direction is realized, and the torque transmission on the two shafts is realized through the engagement of the two joint parts. In addition, the axial stress of the end face of the operation shaft of the reagent box can be reduced, so that the abrasion is reduced, and the movement precision is improved. Meanwhile, the assembly is convenient.
