Problems solved by technology
[0004] The above-mentioned existing technical solutions have the following defects: the two sides of the ruler on the handle have an angle of less than 90 degrees. When it is necessary to detect the gap between two arcuate surfaces or the distance between two spheres, The detection error is extremely large; at the same time, the detection data is determined by sliding the cursor on the side wall of the gap to be measured. Since the cursor is easy to slide, it is easy to cause errors when reading data

The invention relates to a feeler gauge which comprises a measuring part and a handle part. The measuring part comprises a fixed ruler and a movable ruler; a convex block is fixedly arranged on the fixed ruler; a threaded rod is rotationally connected to the convex block; the movable ruler comprises a first movable ruler body and a second movable ruler body, connecting pieces are fixedly connectedto opposite ends of the first movable ruler body and the second movable ruler body, the first movable ruler body is parallel to the second movable ruler body, a threaded hole is formed in the secondmovable ruler body and connected to the threaded rod in a threaded mode, and the movable ruler is parallel to the fixed ruler; the handle part is of a hollow structure, the measuring part is connectedinto the handle part in a sliding mode, scales are arranged on the side edge of the handle part, and the measuring part is perpendicular to a side edge, provided with the scales, of the handle part.The feeler gauge has the advantages of high detection precision and the capability of detecting various gaps.
Description
technical field [0001] The invention relates to the technical field of supervision and testing equipment, in particular to a feeler gauge. Background technique [0002] Feeler gauges are used to measure the size of the gap. When checking whether the measured size is qualified, it can be judged by this method, or by the inspector according to the tightness of the fit between the feeler gauge and the surface to be tested. [0003] The Chinese patent with authorized notification number CN2495984Y discloses a construction feeler gauge, which includes a handle and a scale body fixed on the handle. A slide plate is arranged in the inner cavity of the cursor formed between the scale bodies, one side of the slide plate fits with the scale body, and a spring is set between the other side and the inner wall of the cursor. [0004] The above existing technical solutions have the following defects: the two sides of the ruler on the handle have an angle of less than 90 degrees. When it...
