Abstract

A high-accuracy stepped hole measuring caliper relates to the technical field of construction engineering, including a caliper whose middle part is rotatably connected with a rotary block. The high-accuracy stepped hole measuring caliper is used in conjunction with the ball and the gravity block. Before fixing the measuring device, the device is inserted into the stepped hole, and the calibration disc is rotated to make the ball roll in the movable groove. When the ball rolls to the shrapnel , press the shrapnel downwards, so that the second spring is compressed, and the gravity block is under the downward pressure of the second spring, but because the gravity block is not vertically downward, the gravity block is subjected to the friction force of the rubber pad, and cannot stretch out the calibration plate. When the gravity block is turned vertically downward, the gravity block will pop out the calibration plate under the action of spring 2. At this time, the caliper is in a vertical or horizontal state, thereby achieving the purpose of calibration and improving the accuracy of the measurement results , At the same time, during the measurement, the angle of the caliper can be changed by rotating the rotary block and inserting the block to increase the measurement range.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a high-precision stepped hole measuring caliper. Background technique [0002] The measuring caliper for construction engineering is the main measuring device used to measure the stepped hole. The accurate value of the stepped hole is measured by the measuring caliper, so as to obtain various data and judge whether the construction project is qualified. [0003] Most of the current measuring calipers directly measure the aperture during use, without fixing and calibration devices, resulting in the measured results may be greater than the actual results, resulting in inaccurate measurement results, which easily affects the judgment of whether the construction project is qualified. [0004] Therefore, we propose a high-precision stepped hole measuring caliper to solve the above problems. Through the cooperation of the movable clamping block and the rotating rod, af...
