ADJUSTABLE BALL-TYPE UNIVERSAL JOINT

摘要

The present invention discloses an adjustable ball-type universal joint, which is distinct from the conventional ball-type universal joint where the ball-type joint is hard to rotate stably or fixed securely. In the present invention, an elastic element is added to the bottom of the ball-type joint, providing elastic resilience to stabilize the rotation of the ball-type join and secure the fixation of the ball-type joint. Therefore, the present invention can improve performance and quality, save manpower and materials, reduce fabrication cost, and upgrade commercial competitiveness for the ball-type universal joint.

主权项

1. An adjustable ball-type universal joint comprising
a body having an assembly socket; a ball-type joint arranged inside said assembly socket; and an elastic element arranged inside said assembly socket, storing elastic resilience, elastically supporting a bottom of said ball-type joint, and limiting vertical displacement of said ball-type joint in said assembly socket,wherein an external force acts on said ball-type joint to overcome said elastic resilience and press down said ball-type joint to make said elastic element together with said ball-type joint descend along said assembly socket and rotate said ball-type joint to tilt to a specified angle, whereafter said external force is removed to let said elastic element release said elastic resilience to move said ball-type joint upward to resume said ball-type joint to an original constrained state and preserve said specified angle securely.
