Lockable display support

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.

Claims

DETAILED DESCRIPTION

(6) Referring to FIG. 1 and FIG. 2, a lockable display support comprises three parts, i.e. a base 1, a cantilever 2 and a suspension assembly 3; in the illustrated example, the base 1 is a wall-hung structure which can be directly locked on a wall; it also can be a stand support or floor support column which can be locked on the desktop or the ground.

(7) The cantilever 2 comprises an upper cover 21, a lower cover 22, an upper shaft seat 23, a lower shaft seat 24 and a lockable pneumatic rod 25. The upper cover 21, the lower cover 22, the upper shaft seat 23 and the lower shaft seat 24 are hinged into a four-link mechanism. Specifically, the lockable pneumatic rod 25 is hinged on the diagonal shaft points of the four-link mechanism. More specifically, one end of the lockable pneumatic rod 25 is hinged on the upper hinge point of the upper shaft seat 23, the lower end is hinged on the lower hinge point of the lower shaft seat 24, which forms a locking support when the lockable pneumatic rod 25 is locked, that is, the distance between the two diagonal hinge points is locked, so that the four-link mechanism can be reliably locked at a specific angle; a linear control end 26 for controlling the lockable pneumatic rod 25 is arranged on the suspension assembly.

(8) The suspension assembly 3 comprises an L-shaped arm 31, a connector 32, a keyboard support 33 and an upper positioning shaft 34; the upper positioning shaft 34 is locked at the bending of the L-shaped arm 31 and is downwardly movably inserted in the upper shaft seat 23 and can freely rotate about the upper shaft seat; the connector 32 is positioned at the upper end of the L-shaped arm 31 by a shaft for hanging the display 4; the keyboard support 33 is positioned at the lower end of the L-shaped arm 31 by a shaft for holding the keyboard and mouse, and providing a space for input operations; the linear control end 26 of the lockable pneumatic rod is arranged on the keyboard support 33, so as to facilitate manipulation and adjustment.

(9) The connector 32 and the keyboard support 33 are positioned on the L-shaped arm 31. The L-shaped arm 31 is provided with two fixed shaft lugs 311, and the connector 32 and the keyboard support 33 are provided with a movable shaft lug 321 respectively, one fixed shaft lugs 311 and one movable shaft lag 321 are positioned by a shaft 35 together; the arcuate outer edge of the fixed shaft lug 311 is provided with an arc-shaped slot 312, a side of the movable shaft lug 321 is provided with a limit rod 322 that is constrained in the arc-shaped slot 312. That is, it only moves in the arc-shaped slot 312, limiting the pitch adjustment range of the display 4 and the keyboard support 33.
