Embodiment Construction

[0025] The structure of the present invention will be further described below in conjunction with the accompanying drawings and through embodiments. It should be noted that this embodiment is illustrative rather than limiting.

[0026] A locking device for the core components of a gravimeter, see Figure 1-4 , its invention point is: mainly including fixed bracket 1, limit assembly, locking executive assembly, locking spring 4, unlocking assembly

[0027] The fixing bracket is the base part of the locking device, and is used for installing other parts of the locking device, and the fixing bracket is provided with a limit assembly installation hole.

[0028] The limit assembly is integrally fixed and inserted in the installation hole of the limit assembly, and the limit assembly is used to limit the radial and upper and lower limit positions of the locking actuator assembly; the limit assembly consists of a limit cylinder 5 and an adjustment sleeve 8 consists of two parts. T...

Abstract

The invention relates to a locking device for a core component of a gravimeter. The locking device comprises a fixing support, a limiting assembly, a locking execution assembly, a locking spring and an unlocking assembly. The limiting assembly is fixedly inserted into a limiting assembly mounting hole in the fixed bracket; the limiting assembly is provided with a center hole, an upper limiting table top and a lower limiting table top. The locking execution assembly is coaxially inserted into a center hole of the limiting assembly; a central through hole is formed in the locking execution assembly and is composed of a locking spring mounting hole section, a transition hole section and a locking action hole section from top to bottom, and the locking action hole section is a conical hole matched with the outer conical surface on the locking component in shape; a limiting matching part is arranged at the position, close to the lower end part, of the locking execution assembly; the locking spring is mounted in the locking spring mounting hole section, and a pressure spring piece is fixed to the upper end of the limiting assembly, so that the lower end of the locking spring is in downward pressing contact with the locking execution assembly; the unlocking assembly is connected to the lower portion of the fixing support and makes contact with the lower end of the locking execution assembly. According to the invention, the uniqueness of the position of the locked part is ensured.

Description

technical field [0001] The invention belongs to the field of gravitational acceleration measuring instruments, and in particular relates to a locking device for a core component of a gravimeter. 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 equipment 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 compone...
