Abstract

A display strut adjusting structure is located on a base seat of a display, comprises an altitude adjusting device and an angle adjusting device. An arc-shaped suppressing plate is located on a sliding plate of the altitude adjusting device, which can push the torsion member of an outer frame component with stability thus enhance the smoothness of the altitude adjusting operation. A braking bar at the end of the outer frame component restricts rotation, and allows strengthening of the stability of the adjusted angle between the display strut adjusting structure and the base seat. A concave ring is designed on the braking bar, when depressed the braking bar causes the concave ring to align with the pivot end, the outer frame component will rotate through the concave ring in relation to the pivot end, thus, adjusting the angle of the display strut adjusting structure and the base seat.

Claims

1. A display strut adjusting structure is located on a base seat of a display, comprising:

an altitude adjusting device, comprising;

a sliding plate, the two sides of the sliding plate having a pair of sliding grooves, and an arc-shaped suppressing plate is located on the sliding plate;

an outer frame component having a pair of sliding tracks located on the two sides of the outer frame component, the pair of sliding tracks is embedded into the pair of sliding grooves, so that the sliding plate can glide within the outer frame component;

at least one torsion member includes a fixed end and a curly end, the fixed end is fixed on the top of the outer frame component, the arc-shaped suppressing plate is suppressed on the curly end, to push the curly end and allow the torsion member to produce an elongating motion or a coiling motion, so as to shift the relative location of the sliding plate on the outer frame component, thus adjusting the altitude of the display; and

an angle adjusting device, includes;

a pivotal element which is fixed on the base seat, the two sides of the pivotal element having a pivot end respectively, the two pivot ends are pivotal to the ends of the outer frame component, the angle of the display strut adjusting structure and the angle of the base seat can be adjusted by the pivotal element;

a braking bar which runs through the end of the outer frame component and located on one side of the pivot end, one end of the braking bar having a reduced portion, and a concave ring is located on the braking bar;

a compression spring is disposed on the reduced portion of the braking bar, wherein the braking bar is supported by the elasticity of the compression spring, the braking bar will continue its contact with the pivot end under a normal condition, so as to restrict the rotation of the outer frame component, when the braking bar is depressed, causing the concave ring of the braking bar align with the pivot end, the outer frame component can rotate through the concave ring in relation to the pivot end, thus, adjusting the angle of the display strut adjusting structure and the angle of the base seat, after the angle has been adjusted, through the elastic restoring force of the compression spring, the braking bar will contact the pivot end again and localized.

2. The display strut adjusting structure according to claim 1, wherein the outer frame component further includes a position restricting slit and a position restricting rod is located on the sliding plate, one end of the position restricting rod is movable within the position restricting slit, so as to strength the localization between the sliding plate and the outer frame component, and to allow a smoother and more accurate sliding movement of the sliding plate on the outer frame component.

3. The display strut adjusting structure according to claim 1, wherein the torsion member can be a torsion elastic piece.

4. The display strut adjusting structure according to claim 1, wherein the reduced portion of the braking bar after running through the outer frame component, can be fixed by a C-shaped ring.
