Description

Technical Field

[0001] This utility model relates to the technical field of stirring structure for fully automatic biochemical analyzers, and in particular to a highly stable stirring structure for fully automatic biochemical analyzers. Background Technology

[0002] A fully automated biochemical analyzer is an instrument used to detect and analyze biological chemical substances, providing information for clinical diagnosis, treatment, prognosis, and health status. The stirring structure is an indispensable and important component of a fully automated biochemical analyzer.

[0003] However, most of the existing fully automated biochemical analyzers are equipped with single-unit stirring structures, which can only stir the material in a single vessel on a rotating plate at a time. They cannot achieve simultaneous stirring operations at multiple stations, resulting in relatively low overall efficiency and effectiveness. Furthermore, the stirring heads are not easy to disassemble and assemble, making it difficult to perform regular maintenance during normal operation. This significantly affects the overall lifespan and limits the overall functionality, leading to a narrow range of applications.

[0004] Based on this, this utility model proposes a highly stable fully automatic biochemical analyzer stirring structure to solve the above problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems existing in the above and / or existing fully automatic biochemical analyzer stirring structure design, this utility model is proposed.

[0007] Therefore, one of the objectives of this utility model is to provide a highly stable stirring structure for a fully automatic biochemical analyzer. By breaking through the traditional single-rod stirring structure of fully automatic biochemical analyzers, it adopts a disc-type multi-station stirring structure that is compatible with the rotating vessel support plate of the fully automatic biochemical analyzer. This makes the overall structure more compatible with the structure of the fully automatic biochemical analyzer and enables simultaneous stirring of multiple material support vessels according to specific usage requirements, effectively enriching the overall functionality.

[0008] To achieve the above effects, this utility model provides the following technical solution: a highly stable fully automatic biochemical analyzer stirring structure, including a biochemical analyzer platform, a bearing sleeve fixedly installed at the bottom of the biochemical analyzer platform, the upper end of the bearing sleeve penetrating through the upper part of the biochemical analyzer platform, a lifting bearing cylinder movably installed at the upper end of the bearing sleeve, an electric telescopic rod fixedly installed at the bottom of the bearing sleeve, the output end of the electric telescopic rod being fixedly connected to the bottom of the lifting bearing cylinder, a limit sealing plate fixedly installed at the upper end of the lifting bearing cylinder, a rotary motor fixedly installed at the bottom of the limit sealing plate, a rotating receiving rod fixedly connected to the upper end of the rotary motor passing through the limit sealing plate, a receiving protective shell fixedly installed at the end of the rotating receiving rod, and a transmission bearing plate fixedly installed at the middle of the bottom of the receiving protective shell.

The fixed installation position of the lifting sliding limit blocks outside the lifting bearing cylinder corresponds to the opening position of the lifting sliding groove inside the bearing sleeve. The external specifications of the lifting sliding limit blocks correspond to the internal specifications of the lifting sliding groove.

[0010] By adding an adaptive sliding connection structure between the lifting sliding limit block and the lifting sliding groove, the overall sliding smoothness of the lifting bearing cylinder inside the bearing sleeve is improved.

[0014] By employing a meshing transmission structure of drive gears and driven gears, this stirring structure enables multiple stirring rods to perform synchronous and unidirectional stirring operations, effectively improving overall work efficiency and thus enhancing overall performance.

[0016] This allows the mating sleeve to drive the assembled stirring rod to perform continuous, stable, and smooth synchronous stirring operations under the structural action of the meshing connection between the transmission gear and the driven gear.

[0017] As a preferred embodiment of the highly stable fully automatic biochemical analyzer stirring structure of this utility model, the docking sleeve is a hollow sleeve structure, and a positioning hole is provided through the lower side of the outer side of the docking sleeve. A docking assembly block is fixedly installed on the upper end of the stirring rod. The external specifications of the docking assembly block correspond to and match the internal specifications of the docking sleeve. Elastic retaining beads are symmetrically and movably installed on both sides of the outer side of the docking assembly block.

At the same time, the internal specifications of the positioning hole and the external specifications of the elastic retaining beads are compatible with each other.

[0018] By adopting an assembly-type stirring rod structure that can be quickly aligned and inserted with the docking sleeve, the number of stirring rods can be adjusted appropriately according to the specific usage requirements of the fully automatic biochemical analyzer, making it suitable for various usage scenarios and effectively enriching the overall functionality.

[0019] The beneficial effects of this utility model are as follows: By breaking through the traditional single-rod stirring structure of fully automatic biochemical analyzers, this utility model adopts a disc-type multi-station stirring structure that is compatible with the rotating vessel support plate of the fully automatic biochemical analyzer.

In addition, based on the use of the transmission support plate as the stirring rod support structure, a quick-connect assembly structure for the stirring rod is added, which allows for adjustment of the number of stirring rods according to specific usage needs. This effectively improves the overall work efficiency without affecting the overall working performance. Attached Figure Description

[0036] Working principle:

[0037] When the fully automated biochemical analyzer equipped with this structure needs to perform continuous and stable stirring of materials in the vessel, the electric telescopic rod 5 can be activated to drive the lifting support cylinder 4 inside the support sleeve 2. Utilizing the adaptive sliding connection structure between the lifting sliding groove 3 and the lifting sliding limit block 6, the cylinder rises, allowing the rotating support rod 9, supported by the lifting support cylinder 4, to lift the support protective shell 10 and its lower part to a suitable position on the fully automated biochemical analyzer. Then, by activating the rotary motor 8, the rotating support rod 9 rotates, positioning the transmission support plate 13 directly above the vessel to be stirred. Since existing fully automated biochemical analyzers all use a turntable-type vessel support structure, the transmission support plate 13 structure used in this stirring structure is applicable to most fully automated biochemical analyzers on the market. Activating the electric telescopic rod 5 then drives the rotating support rod 9 to rotate the transmission support plate 10... As the carrier plate 13 descends, the stirring rod 18 is stably aligned and inserted into the vessel to be stirred. Then, the stirring motor 11 is started, driving the transmission gear 15 to rotate on the transmission carrier plate 13. Utilizing the meshing connection structure between the driven gear 16 and the transmission gear 15, the docking sleeve 17 drives the stirring rod 18 to perform synchronous rotational stirring operations in the material vessel. The stirring rod 18 can be quickly inserted into the docking sleeve 17 through the alignment matching structure between the elastic retaining bead 21 on the docking assembly block 19 and the positioning retaining hole 20 opened in the docking sleeve 17. This allows for the selection of the appropriate number of stirring rods 18 according to specific usage requirements, and makes the periodic maintenance of the stirring rods 18 smoother, more convenient, and more stable. This effectively enriches the overall functionality and extends the overall service life, thereby effectively expanding the applicability of this structure.
