Integrated multifunctional calipers

Abstract

The invention relates to a measuring tool, provides a linear dimension measurement tool, and particularly relates to integrated multifunctional calipers. The integrated multifunctional calipers have an inside caliper state and an outside caliper state and comprise a pair of caliper arms which are arranged symmetrically and hinged in a crossed mode through a pivot pin, the portion, on one side of the pivot pin, of each caliper arm is the holding section, and the portion, on the other side of the pivot pin, of each caliper arm is the reading section; clamps are arranged at the ends of the clamping sections, the included angle of each clamp and the corresponding caliper arm can be adjusted in the plane determined by the pair of caliper arms, the two clamps of which the front ends are pointed-ends are arranged symmetrically, the clamps are inside calipers when the clamps incline inwards, and the clamps are outside calipers when the clamps incline outwards; a reading device used for reflecting the inside caliper length and the outside caliper length is arranged on each reading section; the clamps are rotatably arranged at the ends of the clamping sections through control screws, and limiting bosses limiting the clamps to incline inwards and outwards to the limiting position are arranged on the two sides of the rear ends of the clamps; the front end of each clamp is shaped like a cone.

Description

technical field [0001] This technology relates to measuring tools, and provides a linear dimension measuring tool, especially an integrated multifunctional caliper, which can be used as an inner caliper when measuring dimensions such as wall thickness, and can be used as an inner caliper when measuring dimensions such as inner hole diameter. It is used as an external caliper and can directly read out the measurement data. Background technique [0002] In the prior art, when measuring linear dimensions such as wall thickness, inner hole diameter, and groove width of parts, inner calipers and outer calipers are often used for auxiliary measurement. After the opening of the calipers corresponds to the size to be measured, the calipers need to be removed. Using other measuring tools to measure the linear dimension of the caliper opening, the test results are affected by the skills of the inspectors, it is difficult to ensure that the caliper opening does not change, and it is al...

Problems solved by technology

[0002] In the prior art, when measuring linear dimensions such as wall thickness, inner hole diameter, and groove width of parts, inner calipers and outer calipers are often used for auxiliary measurement. After the opening of the calipers corresponds to the size to be measured, the calipers need to be removed. Use other measuring tools to measure the linear dimension of the caliper opening. The test results are affected by the skills of the inspectors. It is difficult to ensure that the caliper opening does not change, and it is difficult to ensure the accuracy of the measurement.

In addition, the common caliper in the prior art is a single inner caliper and outer caliper, which has a single function, cannot directly read the measurement results, and cannot meet the requirements of direct and effective measurement.
