Problems solved by technology

However, in the dry-type biochemical analyzer of CN 111921393 A, the multiple rotating drum parts do not rotate separately, and the rotating drum parts in this technology perform revolving motion with the main body rotating disc (solid material mechanism) at the same time. This technical scheme aims to eliminate the corresponding reagent The vortex formed in the container parts, and when each reagent container part can only revolve around, the vortex effect is not significant or does not exist. When the mixed liquid rotates synchronously with the drum parts, due to the revolution speed of the mixed liquid and the drum The parts and the main body turntable have the same revolving speed, so the mixed liquid basically does not have a stirring function. At this time, the known technology mainly changes the state of the mixed liquid in each drum part by changing the revolving speed and the way of traversing to make it disturb

Embodiment 1

[0035] Embodiment 1: The present invention discloses a dissolving and stirring mechanism of a feed unit of a biochemical analyzer, such as figure 1 As shown, it includes an upper disc carrier plate 8 and a lower disc carrier plate 9, both of which are fixed together by an edge link 10, and the edge link 10 can be replaced by a plate structure, so that the upper disc carrier plate 8 and the lower disc carrier plate The disk carrier plate 9 is a whole and can rotate synchronously, and this mechanism is applied as Figure 4 Inside the biochemical analyzer shown.

[0036] like figure 2 As shown, the centers of the upper disc carrier plate 8 and the lower disc carrier plate 9 are respectively equipped with a mandrel 16 through a bearing assembly, specifically, the upper end of the mandrel 16 is installed at the center of the upper disc carrier plate 8 through a thrust bearing 17 In the shaft hole, the lower end of the mandrel 16 is installed in the central shaft hole of the lowe...

Embodiment 2

[0043] Embodiment 2: On the basis of Embodiment 1, further, between the upper disk carrier plate 8 and the lower layer disc carrier plate 9, a transition gear 32 is installed through a bearing, such as Figure 8 and Figure 9 As shown, the rotating shafts of each transition gear 32 are respectively installed in the corresponding shaft holes of the upper disc carrier plate 8 and the lower disc carrier plate 9 through bushings, each transition gear 32 meshes with the corresponding edge gear 14 respectively, and each transition gear 32 is also meshed with sun gear 15 simultaneously. from Figure 9 It can be seen that each transition gear 32 meshes with two adjacent edge gears 14 respectively.

Embodiment 3

[0044] Embodiment 3: On the basis of Embodiment 2, two transition gears 32 arranged radially are designed, and the two transition gears arranged radially mesh respectively to form a gear set, and the gear set meshes with the edge gear 14 and Mesh with the sun gear 15. This design can extend the transmission path and reduce the speed ratio. Simultaneously, this design can also set the lumen at the center of the rotating shaft of each transition gear to accommodate the corresponding reagent container parts. Corresponding drum parts 12 are distributed at different radial positions for selective applications that require different degrees of agitation.

Abstract

The invention discloses a biochemical analyzer feeding unit dissolving and stirring mechanism which comprises an upper-layer disc carrier plate and a lower-layer disc carrier plate; a mandrel is mounted in the centers of the upper-layer disc carrier plate and the lower-layer disc carrier plate through bearing assemblies, a series of penetrating through holes are distributed in the peripheral edges of the upper-layer disc carrier plate and the lower-layer disc carrier plate, and rotary drum components are mounted in the through holes through shaft sleeves; edge gears are fixedly sleeved on the outer sides of the rotary drum components, a central gear is fixed on the mandrel and meshed with the edge gears, a driven gear is arranged on the lower portion or the edge of the lower-layer disc carrier plate, a rotary driving motor is mounted on the base, a driving gear is mounted on a rotary shaft of the rotary driving motor, and the driving gear is meshed with the driven gear. Corresponding reagent container components located on the edges of the upper-layer disc carrier plate and the lower-layer disc carrier plate can autorotate while revolving, the autorotation mixing and stirring effect of a single reagent container component is achieved through autorotation, and the revolution mixing and stirring effect is achieved by changing the revolution speed.

Description

technical field [0001] The invention belongs to the analyzer improvement technology in the field of biochemical technology, and in particular relates to a technology applied to a feed unit of a biochemical analyzer to improve the function of dissolving and stirring. Background technique [0002] A biochemical analyzer, also often called a biochemical analyzer, is an instrument that uses the principle of photoelectric colorimetry to measure a specific chemical composition in body fluids. Because of its fast measurement speed, high accuracy, and small consumption of reagents, it has been widely used in hospitals at all levels, epidemic prevention stations, and family planning service stations. Cooperating with it can greatly improve the efficiency and benefit of routine biochemical testing. Its sample loading system includes a sample turntable, which can hold dozens of small sample cups. Some analyzers can directly use the test tube containing the sample, and some are equipp...
