Gravity meter locking mechanism

Abstract

The invention relates to a gravity meter locking mechanism which comprises an installation support, 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 driving rod assembly and a lower locking rod driving rod assembly. The driving rod is connected to upper and lower mounting arms of the installation support; the driving wheel is fixedly arranged on the driving rod, and the wheel thickness between the upper and lower driving wheel acting surfaces of the driving wheel is gradually changed; the upper locking disc and the upper locking spring are mounted on the upper mounting arm, and the lower locking rod and the lower locking spring are mounted on the lower mounting arm; the upper locking disc driving rod assembly is installed in an upper limiting guide sleeve fixed to the upper mounting arm, the lower end of the upper locking disc driving rod assembly makes contact with the upper driving acting face, and the upper end of the upper locking disc driving rod assembly makes contact with the lower end of the upper locking disc; the lower locking rod driving rod assembly penetrates into a lowerlimiting guide sleeve fixed to the lower mounting arm, the upper end of the lower locking rod driving rod assembly makes contact with the lower driving acting face, and the lower end of the lower locking rod driving rod assembly makes contact with the upper end of a rod head of the lower locking rod. The mechanism is firm in locking and good in reliability.

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] The acceleration of gravity g is a basic geophysical constant, but it will change with factors such as terrain and geology, altitude, and the position of the moon. Accurate measurement of acceleration of gravity 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, which is a precision measuring instrument with a complex structure and many parts. For precise measurements of 10 -9 g~10 -7 Changes in the acceleration of gravity at the g level require the core measurement components of the gravimeter to be very sensitive to changes in acceleration; Damage to fragile gravimeter core measurement components. [0003] In order to solve t...
