Ball rotating shaft structure capable of converting degree of freedom and having dynamic balance

Abstract

The invention discloses a ball rotating shaft structure capable of converting the degree of freedom and having dynamic balance. A ball rotating shaft comprises an outer shell which can accommodate the ball rotating shaft to rotate in an inner cavity, a non-slip ring and an elastic push block; the ball rotating shaft is characterized by being divided into a left part, a middle part and a right part, the left part is provided with a torsional spring clamping groove and a convex shaft, the outer side of the middle part is provided with a torsional spring clamping groove and a round hole, the convex shaft of the left part can penetrate through the round hole to be fixedly connected with a screw hole of the right part, and then a complete spherical body can be formed and makes contact with the non-slip ring according to the principle that the areas of the left part and the right part are large, and the larger tightness degree range and the positioning effect are generated; as the area of the middle part is small, the effect of delaying resistance is achieved, movable shooting and dynamic balance operation can be carried out, when the middle part needs to be locked and fixed, the middle part can be locked and fixed by adjusting a locking push block knob, the two-degree-of-freedom and three-degree-of-freedom conversion of universal positioning mobile shooting and the dynamic balance effect are achieved, and the ball rotating shaft has the advantages of being easy to convert and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of a ball rotating shaft, in particular to the technical field of two-degree-of-freedom and three-degree-of-freedom conversion and dynamic balance positioning. Background technique [0002] With the advent of the era of artificial intelligence, mechanical automation and robot arms, including electronic digital products, use ball-rotating shaft structures to achieve conversion, carrying, and movement in two-degree-of-freedom and three-degree-of-freedom spaces. Most of the ball shafts of the ball heads used in the most common cameras and cameras can only be positioned statically for shooting, or the ball needs to be adjusted to a fixed position to align with the pin hole, and the pin is inserted into the ball hole to position and realize mobile shooting , it is very inconvenient to use, and when shooting vertically and horizontally, the left and right angles cannot be adjusted at will. Therefore, it is neces...

Problems solved by technology

Most of the ball shafts of ball heads used by cameras and video cameras can only be positioned statically for shooting, or the ball needs to be adjusted to a fixed position to align with the pin hole, and then insert the pin into the ball hole to position and realize mobile shooting , it is very inconvenient to use, and when shooting vertically and horizontally, the left and right angles cannot be adjusted at will. Therefore, it is necessary to develop a new ball shaft structure, so that it does not need to use pins, and there is no angle limit. The ball shaft can be positioned at will to achieve Mobile shooting, diversification of angles, conversion between two degrees of freedom and three degrees of freedom becomes easier and easier to use
