Description

A multipurpose vernier caliper

technical field

The utility model relates to a vernier caliper, in particular to a multipurpose vernier caliper which can accurately measure multiple values at the same time.

Background technique

At present, the known vernier caliper can measure the length, inner and outer diameter, and depth of the object. In the concrete carbonation experiment, it is necessary to measure the carbonation depth of the concrete split surface. Due to limited technology, the split surface is generally an uneven plane. Inaccurate positioning leads to inaccurate measurement results and affects research; in some civil engineering inspections, such as the inspection of steel rust pits, it is necessary to determine the depth of the lowest point, but the existing vernier depth gauge has too large a cross-sectional area to be able to Accurately measure rust pit depth.

Contents of the invention

In order to solve the shortcomings of the existing vernier caliper, the utility model provides a multi-purpose vernier caliper, which is easy to operate, accurately locates the measurement boundary of the non-flat plane, accurately measures the width of the non-flat plane, and can also accurately locate the lowest point of the rust pit of the steel bar, and accurately measure the steel bar The depth of rust pits improves the accuracy of measurement data.

The technical solution adopted by the utility model to solve the technical problem is: a multi-purpose vernier caliper, which includes an inner measuring claw a, an inner measuring claw b, a fastening screw a, a ruler body, a depth gauge, a vernier, a fastening screw b, Vertical main ruler, outer measuring claw b, outer measuring claw a; the vernier caliper is provided with a ruler body with a scale, and the ruler body is finely fitted with a vernier with a scale to improve the accuracy of measurement data; the upper end of the vernier A fastening screw a is provided to fix the position of the vernier; symmetrical and equal-sized inner measuring claws a and b are arranged on the front end of the ruler body for inner diameter measurement; an outer measuring claw a is arranged under the front end of the ruler body , the front part of the vernier is connected vertically downward with a vertical main ruler with a scale, and the outer measuring claw b matching the outer measuring claw a in parallel is installed on the vertical main ruler with precision fit and sliding, and the outer measuring claw b is equipped with The same downward measuring scale as the vernier, the outer measuring claw b moves up and down along the vertical main scale; the outer measuring claw b is provided with a fastening screw b for fixing the outer measuring claw b; behind the ruler The end is provided with a tip-shaped depth gauge connected with a vernier for depth or length measurement. When measuring the carbonation depth of concrete, if the splitting method is used, use the outer measuring claw a and the outer measuring claw b to align the inner edge and outer edge of the carbonized part of the split surface respectively. When the height of the outer edge is lower than the inner edge, along the The vertical main ruler slides the outer measuring claw b downward, so that the outer measuring claw b is close to the outer edge of the carbonized part of the split surface, so as to improve the accuracy of the measurement data; when measuring the depth of the steel rust pit, align the depth gauge with the rust pit At the lowest point, just read the value of the vernier caliper.

The utility model has the beneficial effects of simple operation, accurate positioning of non-flat plane measurement boundaries, accurate measurement of concrete carbonation depth, accurate positioning of the lowest point of steel bar rust pits, accurate measurement of steel bar rust pit depths, and improved accuracy of measurement data.
