Abstract

The invention discloses an inner diameter measuring instrument, and the measuring instrument comprises an operating rod. A right side of the inner cavity of the operating rod is provided with a forwarding and reverse motor, and a bearing is fixedly connected with the left side of the inner cavity of the operating rod. The output end of the forwarding and reverse motor is fixedly connected with a cylinder, and the left side of the cylinder is in cup joint with the inner wall of the bearing. The surface of the cylinder is provided with a spiral sliding groove, and the inner wall of the spiral sliding groove is slidably connected with a sliding rod. The setting and cooperation of the operating rod, the forwarding and reverse motor, the bearing, the cylinder, the spiral sliding groove, the sliding rod, a first sliding rail, a first sliding block, a second sliding rail, a second sliding block, a fixed block, a fixed plate, a receiving plate, a moving plate, an infrared range finder, a through hole, the handle, a housing, a single-chip microcomputer, a wireless receiving module, a touch display screen and a wireless transmitting module solves a problem that a conventional measuring instrument is inconvenient for a user to use. When the measuring instrument detects the inner diameter of an object, the operation process is simple and the detection efficiency is high.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to an inner diameter measuring instrument. Background technique [0002] The diameter of the inner circle of a circular object is called the inner diameter, which is usually measured directly by a micrometer or a vernier caliper, and the symbol is φ. [0003] A measuring instrument is needed to measure the inner diameter of a circular object, but the existing measuring instrument is not convenient for users to use, and the operation is cumbersome when detecting the inner diameter of the object, thereby reducing the efficiency of the measurement and wasting the user's time. Reduced utility of gauges. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides an inner diameter measuring instrument, which has the advantages of being convenient for users to use, and solves the pr...
