Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of microscope object slides, and relates to a metal object slide for inverted metallurgical microscope. BACKGROUND
[0002] An object slide is a thin piece used for placing a sample when observing things with a microscope. When observing microstructures with an inverted metallurgical microscope, an ordinary metal object slide only has a central hole, and different object slides only differ in the diameters of the holes, and the diameters of each hole differ greatly. For the observation of small-size sample metallurgical microstructures, the sample usually needs to be inlaid to be placed on the object slide without falling off, but in actual production inspection, small-size parts are often directly taken for sample preparation and observation. If the inlaid observation is continued, a large amount of inlaid time and a large amount of inlaid material are consumed, and the time cost and economic cost are increased. When small-size parts are directly inlaid for sample preparation and observation, the size of the hole on the original object slide often does not match, so that the sample cannot be placed on the object slide, and even the objective lens of the microscope is scratched. SUMMARY
[0003] The utility model provides a metal object slide for inverted metallurgical microscope that is simple in structure and convenient to use, has a plurality of holes of different sizes, and can stably place small-size parts without inlaying, thereby greatly reducing the cost.
[0004] The utility model provides a metal object slide for inverted metallurgical microscope that is simple in structure and convenient to use, has a plurality of holes of different sizes, and can stably place small-size parts without inlaying, thereby greatly reducing the cost.
[0005] As an improvement, the circular holes are four, and are sequentially arranged on the upper part of the object slide. The diameters of the four circular holes are 3mm, 5mm, 7mm and 9mm respectively.
[0006] Further, the rectangular holes are two, and are arranged on the middle part of the object slide body below the circular holes. The widths of the two rectangular holes are 3mm and 4mm respectively.
[0007] Further, the triangular hole is arranged on the right side of the rectangular hole, and the triangular hole is an equilateral triangle hole with a side length of 10mm.
[0008] Further, the curved hole is arranged below the rectangular hole, and the width of the curved hole is 2mm.
[0009] Finally, the bottom of the slide body is formed with an inner groove, and the edge of the slide body is provided with an inclined chamfer.
[0010] Compared with the prior art, the metal slide for inverted metallographic microscope has the advantages that: the metal slide body is provided with a plurality of circular holes with different diameters, rectangular holes with different sizes, triangular holes and curve holes, so that small-size parts can be stably placed on the metal slide without falling and scratching the objective lens when observing the metallographic microstructure of the small-size parts, thereby saving test materials and being applicable to rapid detection of the metallographic microstructure of irregular small-size parts and greatly shortening the test time.
