Abstract
The invention discloses a zero-length spring, a connecting structure of a zero-length spring and a dynamic gravity meter. The zero-length spring includes a deformation region and linear regions arranged at the two ends of the deformation region; and the deformation region and the linear regions are formed by integrated metallic reed processing. Connecting points of the deformation region and the linear regions are located at the axis of the deformation region; and the axes of the linear regions and the axis of the deformation region are superposed. A traditional structure based on cooperation of a hook and a suspension fiber is removed at the end portion of the zero-length spring and the linear regions are formed at the two ends of the spring directly, so that connecting assemblies of a dynamic gravity meter can clamp the zero-length spring directly like clamping the suspension fiber. In addition, the invention also discloses a connecting structure of a zero-length spring and a dynamic gravity meter using the zero-length spring. The structure of the improved zero-length spring is simplified and the accumulated error is reduced, so that the positioning precision requirement of the dynamic gravity meter is loosened, the assembling difficulty is reduced, and the assembling process is simplified.
