Biological sample detection instrument convenient to adjust

Abstract

The invention discloses a biological sample detection instrument convenient to adjust. The biological sample detection instrument comprises a probe three-dimensional rotation positioning mechanism anda base. The probe three-dimensional rotation positioning mechanism comprises three layers which are rotationally connected in an up-down manner. The upper layer comprises a main box body. The middlelayer is a hollow circular ring plate. The lower layer is a rectangular branch box body. The main box body is rotationally supported in an annular sliding rail on the hollow circular ring plate through a plurality of uniformly distributed pulleys arranged at the bottom of the main box body. The bottom of the hollow circular ring plate is fixedly connected with the rectangular branch box body. Therectangular branch box body is fixedly connected to the top wall of the base. A transverse plate is fixedly connected to the inner wall of the rectangular branch box body. An objective table is connected to the top wall of the transverse plate in a sliding manner. A through groove matched with the objective table is formed in the side wall of the rectangular branch box body. A biological sample detection head can be conveniently adjusted, so that detection data with the relatively high precision is convenient to obtain, operation is simple and convenient, the working efficiency of biological sample detection is effectively improved, and the maximum probe movement range is realized on the basis of small-sized sliding rail design; and compared with traditional design that a probe is rotatable on a three-dimensional positioning framework, the adjustable measurement range is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of biological monitoring devices, in particular to an easily adjustable biological sample detection instrument. Background technique [0002] Biological samples usually refer to plant flowers, leaves, stems, roots, seeds, etc., and animal (including human) body fluids (such as urine, blood, saliva, bile, gastric juice, lymph fluid, and other secretions of organisms, etc.), hair , muscle and some tissues and organs (such as thymus, pancreas, liver, lung, brain, stomach, kidney, etc.) and various microorganisms. [0003] In order to conduct research on organisms better, biological samples are often detected in the prior art, but the biological sample detection instruments in the prior art are often only convenient for the overall detection of biological samples when detecting biological samples. When local detection of biological samples is required, it is necessary to take out the biological samples and plac...

[0003] In order to conduct research on organisms better, biological samples are often detected in the prior art, but the biological sample detection instruments in the prior art are often only convenient for the overall detection of biological samples when detecting biological samples. When local detection of biological samples is required, it is necessary to take out the biological samples and place them again, and then use the detection instrument for detection, so not only the operation is troublesome, but also the efficiency is low. Therefore, an easy-to-adjust biological sample detection instrument is particularly important. In the patented technology, the commonly used structure to realize the three-dimensional movement of the probe is to use three-dimensional slide rails to nest each other and then place the probe on one of the dimension slide rails for combined positioning, such as the patent document CN204169950U, but this design has a The three-position movement of the defect probe is always located in one quadrant. If the target area to be measured is large, a larger slide rail is required to match the full range coverage
