Abstract

The present invention discloses a measuring caliper used for buildings capable of measuring multiple angle step hole diameters, pertaining to the technical field of building surveying. The caliper comprises a step wall. The left side of the step wall is inserted with a measuring caliper. The middle part of the measuring caliper is fixedly connected with a turning block via a connecting rod, the middle part of the turning block is fixedly connected a uniformly-distributed rewinding device. The measuring caliper used for the buildings capable of measuring multiple angle step hole diameters is used combining with a fixing seat and a sucker. When used, the whole measuring caliper is firstly sucked on the surface of the step wall via the sucker, then a second toothed bar is turned by using a tool, and the second toothed bar can drive a piston rod to move towards the middle part of the fixing seat, pumping the air in a piston sleeve, allowing the sucker to suck more tightly and ensuring thatthe measuring caliper can not move during measurement, so that the accuracy of measurement data is ensured, the effect of improving the precision is realized, the measurement error is reduced, and the reliability of the measurement data is ensured.

Description

technical field

[0001] The invention relates to the technical field of building measurement, in particular to a building measuring caliper capable of measuring the diameters of stepped holes of various angles. Background technique

[0002] There will be stepped holes during the construction of the building. After construction, these stepped holes need to be judged by measuring tools. At present, the main equipment used to measure the stepped hole diameter is the building measuring caliper. When measuring, the measuring caliper is inserted into the stepped hole Among them, the measurement method is simple by opening the measurement caliper, but the current measurement caliper will encounter the following problems during measurement:

[0003] When measuring, it cannot be guaranteed that the measured data of the measuring caliper is the real data of the aperture, because the measuring caliper cannot be guaranteed to be perpendicular to the measuring surface during the measureme...
