An elevation-adjustable display screen support arm includes arm shaft with box-like shaft body, balance adjustment mechanism accommodated in box-like shaft body and including gear train, first sliding tooth rack, second sliding tooth rack and tension spring, and display screen mounting head including body block, first guideway, second guideway and connection panel. When adjusting the elevation of the supported display screen, body block is driven to move first sliding tooth rack in rotating gear train, causing gear train to move second sliding tooth rack in driving actuating plate to stretch or compress tension spring, and thus, rotation of gear train causes tension spring to provide a corresponding torque that is acted upon first sliding tooth rack to control upward or downward movement of display screen mounting head and supported display screen in stepless manner.

Elevation-adjustable display screen support arm

A height-adjustable table includes a table top with two support block units, a linkage mechanism including first and second linkages respectively pivotally connected to the support block units, and a lifting control mechanism including first and second sliding tooth racks respectively slidably mounted in respective sliding open chambers of the support block units and respectively pivotally connected to first and second legs of the first and second linkages, two lock mechanisms with center gears thereof meshed with the first and second sliding tooth racks and two operating handles operable to lock/unlock the center gears for allowing the first and second linkages to be extended out or received so as to further adjust the elevation of the table top.

Height-adjustable table

A single lever-operated height-adjustable table includes a table top with two bottom guide rails, a base plate, a linkage system including two scissors linkages, two pairs of coupling rods pivotally coupled between the scissors linkages and the base plate and loaded with torsion springs and sliding roller sets respectively pivotally connected to the scissors linkages by respective pivot bolts and rotatably movably mounted in the guide rails, and a lifting control system for controlling lifting of the table top through one single operating lever.
