Abstract

The invention, firstly, discloses a cam which comprises a cam body, wherein the outer contour of the cam body comprises a first arc section and a second arc section, and a first curve section and a second curve section are arranged between the two ends of the first arc section and the two ends of the second arc section respectively; the first arc section, the first curve section, the second arc section and the second curve section define a closed curve; a rotating shaft is arranged on the cam body, the circle centers of the first arc section and the second arc section are both located on the rotating shaft, and the curvature radius of the first arc section is smaller than that of the second arc section. An eccentric shaft is arranged on the cam body, and the connecting line between the axis of the eccentric shaft and the axis of the rotating shaft intersects with the first arc section or the second arc section. The invention further discloses a one-way intermittent conveying mechanism adopting the cam, a test strip conveying mechanism adopting the one-way intermittent conveying mechanism, and a sample analyzer.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, in particular to a cam, a one-way intermittent transmission mechanism using the cam, a test strip transmission mechanism and a sample analyzer using the one-way intermittent transmission mechanism. Background technique [0002] During the transmission process of the test strip, the horizontal and vertical movement strokes are relatively short. The existing test strip transmission mechanism has multiple implementation methods: 1) using two motors to control the operation and formation in the horizontal and vertical directions respectively, which will lead to a complex structure and high cost of the transmission mechanism; 2) using a synchronous belt Transmission, the transmission rod on the synchronous belt will be stained with urine and cannot be cleaned, and the parallelism of the two synchronous belt transmission rods is not easy to ensure; 3) Using the connecting rod transport ...
