Locking device for camera platform

A locking device for camera platform, comprises:

• a housing, for preventing the components from exiting;
• in said housing from the top down are configured:
• a sphere, for providing a support to the camera;
• a lower damping assembly having a inclined or spheric bottom surface, arranged underneath said sphere, for providing a damping to the upward and downward movement of said sphere;
• wherein, said lower damping assembly is a non-metallic elastic component in one-body form;
• a locking mechanism, arranged underneath said sphere, for working with said housing to lock said sphere inside the housing, comprising a primary regulating assembly for ordinary regulation and a secondary regulating assembly for fine regulation;
• said primary regulating assembly comprises a primary screw bolt, and a primary knob configured at the end of the primary screw bolt and arranged outside the housing;
• said primary screw bolt has two screw threads that are reversely structured to each other;
• two primary driving components having inclined surfaces are in threaded connection with corresponding screw threads on the primary screw bolt;
• the inclined surfaces of the two primary driving components are oppositely arranged to each other, and said primary driving components are connected to the inclined or spheric bottom surface of the lower damping assembly through their inclined surfaces, for driving the sphere to move up and down through their reverse movement;
• said secondary regulating assembly for fine regulation comprises a secondary knob arranged on the primary screw bolt and on the same side as the primary knob;
• an upper damping assembly is configured between the sphere and the housing for providing the damping for the upward movement of the sphere, and said lower damping assembly is in movable connection with the internal wall of the housing;
• said primary regulating assembly also comprises a primary fixing assembly, connected to the housing, for preventing the primary screw bolt from exiting;
• a platform base, arranged underneath said locking mechanism, and fixedly connected to the housing, for providing a support to said locking mechanism;
• wherein, said platform base from the top down comprises a shim arranged underneath said locking mechanism and connected to it;
• a snap spring, arranged in the slot on the internal wall of the housing;
• a platform base supporting assembly, arranged underneath the snap spring and connected to it, so as to provide a support to said platform;
• a platform base locking mechanism connected to said platform supporting assembly, for locking said platform base.
