Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model comprises a support 1, is provided with a flat column elastic body 2 in support 1, and the middle part four direction of elastic body 2 sets to the concave respectively, makes the two ends of elastic body 2 thick, and the middle part forms a thin flat column strain regions 3.The top of elastic body 2 one ends is fixedly connected with a upper bracket 6 by bolt 4 with gluing 5, the bottom of elastic body 2 other ends is fixedly connected with a lower carriage 7 by bolt 4 with gluing 5.Be symmetrically arranged with one by gluing fixing strain ga(u)ge 8 in that an end of strain regions 3 is upper and lower, strain ga(u)ge 8 connects the dynamometry control system by output line 9; Strain regions 3 other ends are forward and backward to be symmetrically arranged with one by gluing fixing strain ga(u)ge 10, and strain ga(u)ge 10 connects the dynamometry control system by output line 11.Strain regions 3 between upper and lower two strain ga(u)ges 8 has been horizontally disposed with a dumbbell shape translot through hole 12, the vertical dumbbell shape vertical slot through hole 13 that is provided with on the strain regions 3 between forward and backward two strain ga(u)ges 10.Dumbbell shape translot through hole 12 and dumbbell shape vertical slot through hole 13 can be respectively laterally and vertically play the effect of strengthening sensitivity to strain regions 3.The vertical slot through hole 13 of strain regions 3 upper and lower settings and the translot through hole 12 of forward and backward setting, be mutual vertical configuration, and be crisscross arranged in left and right direction, be that the center of translot through hole 12 and the center of vertical slot through hole 13 do not overlap, and being positioned at the left and right of strain regions 3 centers, the center of the center of the two and strain regions 3 is and is symmetrical arranged.
