Abstract
The utility model relates to a multi-purpose vernier caliper. The vernier caliper is provided with a caliper body. The caliper body is provided with a vernier having scales and fitted with the caliper body precisely. The upper side of the front end of the caliper body is provided with an inner measuring claw a and an inner measuring claw b. The lower side of the front end of the caliper body is provided with an outer measuring claw a. The front part of the vernier is vertically downward connected with a vertical main caliper with scales. An outer measuring claw b matched with the outer measuring claw a in parallel is installed on the vertical main caliper in precise slide fit. The outer measuring claw b is provided with scales that are identical to the vernier and used for measuring downward. The outer measuring claw b is provided with a fastening screw b. The rear end of the caliper body is provided with a sharp-end-shaped depth ruler connected with the vernier. The multi-purpose vernier caliper is simple in operation, and can position measuring borders of a non-flat plane accurately, measure concrete carbonation depth precisely, position the lowest point of a rust hole of a steel rib accurately and measure depth of the rust hole of the steel bar precisely with high data accuracy.
Description
Technical field
the utility model relates to a kind of vernier caliper, especially simultaneously the multiplex vernier caliper of one of the multiple numerical value of Measurement accuracy.
Background technology
at present, known vernier caliper can be measured object length, internal-and external diameter, the degree of depth, in concrete carbonization experiment, need to carry out carbonation depth measurement to concrete splitting face, because technology is limited, this splitting surface is generally non-flat surface, during with vernier caliper measurement, cannot accurately locate, cause measurement result inaccurate, impact research; In some testing processes of civil engineering work, as the detection in reinforcing bar rust hole, need to measure the degree of depth of its minimum point, but existing vernier depth gauge sectional area is excessive, cannot the Accurate Determining rust hole degree of depth.
Summary of the invention
in order to solve the deficiency of existing vernier caliper, the utility model provides a kind of multiplex vernier caliper, this vernier caliper is simple to operate, accurately non-flat leveling planar survey border, location, accurately measure non-flat whole plane width, also accurately spacer bar rust is cheated minimum point, accurately measures the reinforcing bar rust hole degree of depth, improves measurement data accuracy.
the utility model solves the technical scheme that its technical matters adopts: a kind of multiplex vernier caliper, and this vernier caliper comprises interior measuring claw a, interior measuring claw b, trip bolt a, blade, pit gauge, vernier, trip bolt b, vertical main scale, external pelivimetry pawl b, external pelivimetry pawl a; Described vernier caliper is provided with to be with graduated blade, blade essence to be combined with to be with graduated vernier, for improving measurement data degree of accuracy; Described vernier upper end is provided with trip bolt a, for fixing slider position; Above described blade front end, be provided with large interior measuring claw a and the interior measuring claw b such as symmetrical, for inner diameter measurement; Below blade front end, be provided with external pelivimetry pawl a, described vernier front portion is connected with is vertically downward with graduated vertical main scale, on vertical main scale, precision-fit is slidably fitted with and the external pelivimetry pawl b of external pelivimetry pawl a parallel matched, the upper scale with the downward measurement identical with vernier of external pelivimetry pawl b, described external pelivimetry pawl b moves up and down along vertical main scale; On described external pelivimetry pawl b, be provided with trip bolt b, for fixing external pelivimetry pawl b; Described blade rear end is provided with the most advanced and sophisticated shape pit gauge being connected with vernier, for the degree of depth or linear measure longimetry.While carrying out concrete carbonization depth measurement, if employing split the law, aim at respectively inward flange and the outward flange of splitting surface carbonization part with external pelivimetry pawl a and external pelivimetry pawl b, when outward flange height is during lower than inward flange, along vertical main scale down sliding external pelivimetry pawl b, make the outward flange of the adjacent splitting surface carbonization of external pelivimetry pawl b part, improve the accuracy of measurement data; While carrying out the depth survey of reinforcing bar rust hole, pit gauge is aimed to rust hole minimum point, read vernier caliper numerical value.
the beneficial effects of the utility model are, simple to operate, accurately locate non-flat leveling planar survey border, accurately measure concrete carbonization depth, and also accurate spacer bar rust hole minimum point, accurately measures the reinforcing bar rust hole degree of depth, improves measurement data accuracy.
