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.

Abstract: A liquid crystal display with a height adjustable base assembly includes a base, an inclinable 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 and has a locating groove, and a lock device, which is disposed between the main arm and the base and provides a locating pin member. When the main arm rotates a preset inclining angle relative to the base, the locating pin member is pushed to engage with the locating groove such that the operation of ascending and descending 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.

Abstract: A liquid crystal display includes a liquid crystal panel and a height adjustable base. The height adjustable base further includes a main base, a fixing frame and an elastic locating device. The main base provides at least a sliding rail, which has a stationary member attached to the main base and a movable member capable of sliding along the stationary member. The fixing frame is connected to the movable member for being mounted with the liquid crystal panel. The elastic locating device provides an acting end, which is disposed against the fixing frame for supplying an elastic ascending force to the fixing frame, and a joining end, which is detachably connected to the main base with an elastic coupling force for restoring the elastic ascending force automatically. Therefore, the liquid crystal display can be simply operated to release or restore the ascending elastic force needed at the time of height adjusting the liquid crystal panel.
