Description

Technical Field

[0001] This invention relates to the field of mineralogy and crystal measurement technology, and in particular to an instrument for measuring the angles between crystal faces and the angles between cleavage planes of mineral crystals. Background Technology

[0002] In mineral identification and crystal structure research, the interplanar angles and cleavage angles are important physical parameters. Traditional measurement methods typically use contact goniometers or reflection goniometers, which are complex to operate, have limited accuracy, and require highly experienced operators. Especially in field geological surveys, their portability and rapid measurement capabilities are insufficient, making it difficult to meet the needs of modern mineralogy research and teaching. Summary of the Invention

A support arm 200 is vertically fixed to one side of the horizontal calibration mechanism 110, and an angle measuring disk 300 is mounted on the top of the support arm 200 and rotates therewith. At the center of the angle measuring disk 300, a first measuring pointer 400 and a second measuring pointer 410 are respectively hinged and rotated together. The ends of the first measuring pointer 400 and the second measuring pointer 410 are respectively equipped with tips 420 for alignment. At the center of the angle measuring disk 300, a locking mechanism 500 is installed to fix the positions of the first measuring pointer 400 and the second measuring pointer 410.

[0005] The horizontal calibration mechanism 110 is provided with a horizontally rotatable sample placement platform 600 in the middle, and the sample placement platform 600 is provided with a clamping mechanism 610 for fixing mineral samples.

[0006] The angle measuring disk 300 is equipped with a magnifying glass 700 for observing mineral samples.

[0007] The support arm 200 is a height-adjustable telescopic structure.

[0008] The clamping mechanism 610 is an L-shaped structure with a mirror image. A screw 620 for locking is provided at the bottom of the clamping mechanism 610. Two guide grooves 630 are provided through the sample placement stage 600, which can slide with the end gap of the screw 620.
