A universal hinge is a hinge with the capability of performing stop and hold mechanisms without installing extra stop and/or catch components on an object abutted to the universal hinge. The universal hinge comprises a hinge body, a stop mechanism, and a hold mechanism. Both the stop mechanism and the hold mechanism of the universal hinge are provided by specially shaped hinge knuckles while no extra component is needed. An alternative improvement of the universal hinge is provided by adding a specially designed self-locking spring-bushing assembly which comprises a conical spring and a step-configured ring bushing. The self-locking spring-bushing assembly complying with the stop and hold mechanisms can serve the improved universal hinge with the adjustable stop angle capability.

An improved universal hinge for performing stop function with adjustable stop angles comprising a hinge body embodied with a self-locking spring-bushing assembly in between two hinge knuckles, which comprises a C-spring, which is a conically-shaped ring with an axial opening cut and with teeth formed on the radially wider rim, and a step-configured ring bushing which is a ring with a conical inner surface and two vertical step edges on the upper rim, in which said C-spring and said step-configured ring bushing are installed on the hinge pin in a way that said vertical step edges on said step-configured ring bushing are placed adjacent to a hinge knuckle having matching vertical step edges while said teeth on said C-spring are placed adjacent to the other hinge knuckle having matching teeth such that said conically-shaped outer surface of said C-spring is contacting and is being contracted in said conical inner surface of said step-configured ring bushing so that said step-configured ring bushing and said C-spring are pushed away from each other toward said adjacent hinge knuckles respectively to have said self-locking spring-bushing assembly couple to said other hinge knuckle adjacent to said C-spring through said teeth and hence, said self-locking spring-bushing assembly move\s along with said other hinge knuckle adjacent to said C-spring and, then, said vertical step edges on said step-configured ring bushing and said adjacent hinge knuckle form a stop mechanism.
