Abstract: Disclosed is a spring adjustment supporting arm for a display support. The supporting arm comprises an upright column, a big supporting arm, a medium supporting arm and a supporting arm brace rod. The upright column, the big supporting arm, the medium supporting arm and the supporting arm brace rod are hinged to form a four-bar linkage. The big supporting arm is internally provided with a cavity, and the cavity is internally provided with a spring assembly. It is not necessary to adapt to the weight of a display by means of adjusting a force arm included angle of the spring assembly, and therefore, it is not necessary to arrange a force arm included angle adjustment mechanism, thus simplifying a mechanism of the supporting arm, improving the reliability of production and mounting, reducing production costs, prolonging the service life of a product and preventing potential safety hazards.

Abstract: The application relates to a lockable display support, which comprises a base, a cantilever and a suspension assembly for positioning the display; the cantilever comprises an upper cover, a lower cover, an upper shaft seat and a lower shaft seat which are hinged into a four-link mechanism. Wherein, the cantilever further comprises a lockable pneumatic rod placed between the upper cover and the lower cover, and hinged between the diagonal shaft points of the four-link mechanism. In the application, the angle of the cantilever can be reliably locked by the lockable pneumatic rod when it is locked, which can support not only the display but also the keyboard, thus avoiding upper and lower bounces of the cantilever and providing a stable and comfortable input operation experience; it features a simple structure and a solid support. Especially, it can be wall-hung, providing the support for stand-up input operations.
