US 8,149,572 B2 · Liquid crystal display with a height adjustable base for the panel thereof

Abstract

A liquid crystal display with a height adjustable base assembly includes a base, a main arm, which is provided with a pivotal connection with the base and has slide rails, a panel fixing frame, which is capable of ascending and descending along the slide rails of the main arm and has a lock rod. A plumbing stop block is pivotally connected to the main arm to correspond to the lock rod. When the main arm rotates a preset inclining angular position with respect to the base, the plumbing stop block is urged to rotate by the gravity thereof for the lock rod being pushed to engage with the locating groove of the plumbing stop groove such that the operation of lifting the panel fixing frame with respect to the main arm is locked. Hence, the liquid crystal panel bouncing outward suddenly during unpacked is avoided to secure the safety with convenient operations.
