Abstract

The invention discloses a strain gauge for limiting a torsion angle. The strain gauge comprises a base, a vibration wire and a sensor, wherein the sensor is arranged in the middle of the vibration wire; the base comprises two support seat main bodies, grooves are formed in one surfaces, facing towards each other, of the support seat main bodies; connecting sections are movably connected to two ends of the vibration wire and are inserted into the grooves; at least two limiting blocks are arranged on one surfaces, in which the grooves are formed, of the support seat main bodies, and bayonets areformed between every two limiting blocks; and clamping blocks corresponding to the bayonets are arranged on the side surfaces of the end parts of the vibration wire. According to the strain gauge, the problem that a vibration wire of a traditional strain gauge is easily twisted off when being mounted to a base for use is solved.

Description

technical field [0001] The invention relates to a strain gauge, in particular to a strain gauge for limiting torsion angle. Background technique [0002] With the continuous development of engineering, the application of structural strain monitoring in bridges, highways, railways, subways, tunnels, and pile foundations is becoming more and more important. The monitoring and monitoring of engineering structures has become an important part of construction technology, among which the strain gauge is the main stress testing tool. The vibrating wire in the strain gage is the main core part of the strain gage. Fixed, the relative distance between the two ends of the vibrating wire end changes due to the deformation of the component installed by the strain gauge, and the vibrating wire is stretched to change the vibration frequency of the vibrating wire. The vibration frequency is measured by the sensor and converted to measure strain on the component. However, the traditional s...
