Abstract

The invention relates to a three-dimensional rotating ball pair mechanism capable of achieving free adjustment. The three-dimensional rotating ball pair mechanism comprises a ball pair body and a base, the bottom of the ball pair body is provided with a tip, and the tip makes point contact with the base; a connecting rod group is installed at the upper end of the ball pair body and comprises a vertical rod and a horizontal rod, the top end of the vertical rod is fixedly connected with the midpoint of the horizontal rod, one end of the vertical rod is located in the ball pair body and is collinear with the vertical central line of the ball pair body, and the horizontal rod is located in the ball pair body; and the outer wall surface of the lower side of the ball pair body is provided with afirst sliding groove and a second sliding groove, two first cylindrical plug pins and two second cylindrical plug pins are fixedly installed on the base, one end of each first cylindrical plug pin islocated in the first sliding groove, and one end of each second cylindrical plug pin is located in the second sliding groove. The three-dimensional rotating ball pair mechanism has the advantages that the structure is simple, the freedom degree of overall movement of the mechanism can be effectively reduced, and the mechanism movement uncertainty is reduced.

Description

technical field [0001] The invention relates to a three-dimensional rotating ball pair mechanism capable of free adjustment. Background technique [0002] At present, the ball pair mechanism is an important structure used to realize the three-dimensional rotation function. However, most of the ball pair mechanisms have the problem of imbalance between the degree of freedom and the direction of motion, which makes the movement of the mechanism uncoordinated and cannot achieve continuous and rapid rotation. A request to change direction. The spherical pair structure widely used in the head structure of photography tripod is the most representative. Take the two structures on the three-dimensional and spherical heads that can realize three-dimensional rotation as examples. [0003] (1) Three-dimensional gimbal. [0004] The three-dimensional gimbal uses a handle to surround two nodes in the cross direction to adjust the direction of the water surface and pitch plane respectiv...
