A gravimeter locking mechanism

Abstract

The invention relates to a gravimeter locking mechanism, comprising a mounting bracket, a driving rod, a driving wheel, an upper locking disc, an upper locking spring, a lower locking rod, a lower locking spring, an upper locking disc drive rod assembly and a lower locking plate The locking rod driving rod assembly; the driving rod is connected to the upper and lower mounting arms of the mounting bracket; the driving wheel is fixed on the driving rod, and the wheel thickness between the upper and lower driving wheel working surfaces of the driving wheel is a gradient thickness; the upper locking disc and the upper locking spring are installed on the upper installation arm, the lower locking rod and the lower locking spring are installed on the lower installation arm; the upper locking disc drive rod assembly is installed in the upper guide sleeve fixed on the upper installation arm, its The lower end is in contact with the upper driving action surface, and its upper end is in contact with the lower end of the upper locking plate; the lower locking rod driving rod assembly is inserted into the lower limit guide sleeve fixed on the lower mounting arm, and its upper end is in contact with the lower driving action surface, Its lower end is in contact with the upper end of the rod head of the lower locking rod. The mechanism is firmly locked and reliable.

Description

technical field [0001] The invention belongs to the field of gravitational acceleration measuring instruments, in particular to a gravimeter locking mechanism. Background technique [0002] Gravitational acceleration g is a basic geophysical constant, but it will change with the influence of topography, geology, altitude, lunar position and other factors. Accurate measurement of gravitational acceleration is of great significance in the fields of earth science, resource exploration and even national defense construction. . The special instrument for measuring the acceleration of gravity is called a gravimeter. The gravimeter is a precision measuring instrument with a complex structure and many parts. In order to accurately measure 10 -9 g~10 -7 The g-level gravitational acceleration change requires that the core measurement components of the gravimeter are very sensitive to the change of acceleration; however, during the handling and transportation of the gravimeter, vibr...
