Strain gauge installing apparatus

The utility model discloses a strain gauge installing apparatus used for installing a strain gauge on the surface of a tested object. The strain gauge installing apparatus comprises a positioning block and a pressing lock. The positioning block is provided with a strain gauge installing hole for receiving the strain gauge and a gap of receiving a strain gauge connecting line. The strain gauge installing hole and the strain gauge have same size and shape. The gap is communicated with the strain gauge installing hole. The pressing block cooperates with the strain gauge installing hole. According to the strain gauge installing apparatus, when the strain gauge is installed, the positioning block is first located in order that the accuracy of the position of the strain gauge installing hole of the positioning block is guaranteed; then, the strain gauge coated with an adhesive is placed into the strain gauge installing hole and is pressed by the pressing block in order to be pasted on the surface of the tested object. The strain gauge installing apparatus positions the installing position of the strain gauge, prevents the strain gauge from being displaced in the installing process of the strain gauge and inaccuracy in manual strain gauge pasting, and improves the accuracy of the installing position of the strain gauge.
