Sample rack moving mechanism, sample rack conveying device and sample analyzing equipment

A sample rack conveying device, comprising:

• a storing mechanism capable of being loaded with one or more sample racks, each sample rack is capable of being loaded with one or more containers;
• a sample rack moving mechanism supported by a support base and configured to remove a sample rack on the storing mechanism from its holding position and/or return a sample rack to the storing mechanism, wherein the sample rack moving mechanism comprises:
• a first drive element;
• a cam that comprises a curved contour and is fixedly connected to the first drive element, wherein the cam is capable of being driven by the first drive element to rotate;
• a cam follower that cooperates with the cam and moves along the curved contour of the cam;
• a second drive element;
• a support element that is fixedly connected to the cam follower, wherein the support element is capable of being driven by the cam follower to move vertically so that the support element is capable of being attached to or detached from the sample racks, wherein the support element is capable of being driven by the second drive element to move substantially horizontally, so that the sample rack can be moved horizontally together with the support element;
• a guide groove for holding and guiding the sample rack, wherein a length direction of the guide groove is the same as the substantially horizontal moving direction of the support element, wherein the support element is capable of driving the sample rack to substantially horizontally move along the guide groove;
• and
• a conveying member capable of conveying the support base for supporting the guide groove along a direction substantially perpendicular to the length direction of the guide groove.
