DIMENSION MEASURING DEVICE HAVING BODY WITH CIRCULAR CROSS-SECTION

摘要

The present invention provides a dimension measuring apparatus (100) capable of easily and accurately measuring dimensions of a desired object while two arms are immediately and freely rotating and moving as two arms are combined a body having a circular cross section and not separated from the body when measuring dimensions of not only a mechanical component in the industrial field but also an object having various shapes in daily life. The dimension measuring apparatus (100) comprises: a body (110) in the form of a rod with a circular cross section, and wherein a scale is formed in the surface; and two arms (120) to measure dimensions of an object by rotating the object around the body (110) as a shaft and moving the object in the longitudinal direction of the body (110) while being combined with the body (110). The arm (120) includes: a body combining part (121) combined to surround the circular surface of the body (110) to allow to be moved and rotated in the body (110); and a dimension measuring part (122) formed to maintain verticality with the body (110) in one side of the body combining part (121), and to measure dimensions by being located on the object while moving and rotating.
