Desk frame elevation structure

A desk frame elevation structure comprising:

• a base unit including a base configured to be disposed on a ground;
• an elevation unit including an elevation tube comprised of an outer tube and an inner tube, wherein the inner tube is received in the outer tube and is telescopic relative to the outer tube, wherein the outer tube includes a bottom end fixed to the base and includes an inner periphery and an outer periphery, wherein a bottom plate is securely mounted to the bottom end of the outer tube, wherein a first top plate is securely mounted to a top portion of the outer tube, wherein the first top plate includes a central portion having a first through-hole through which the inner tube extends, wherein the inner tube includes an inner periphery and an outer periphery, and wherein a second top plate is securely mounted to a top portion of the inner tube;
• a desk board unit disposed on top of the elevation unit and coupled to the inner tube to move therewith;
• a movement control unit including a telescopic rod having top and bottom ends and a control board, wherein a control button is disposed on the top end of the telescopic rod, wherein the telescopic rod is disposed in the elevation tube, wherein the top and bottom ends of the telescopic rod are coupled to the outer tube and the inner tube, respectively, wherein the control board is disposed in a position corresponding to the control button, and wherein the control board is operable to selectively press against or not press against the control button;
• and
• a shock absorbing unit including a roller unit, an upper buffer pad, and a lower buffer pad, wherein the roller unit includes a plurality of roller seats and a plurality of rollers, wherein the plurality of roller seats is disposed on the outer periphery of the inner tube, wherein a top face of an uppermost one of the plurality of roller seats forms an abutting edge, wherein each of the plurality of rollers is rotatably mounted on a respective one of the plurality of roller seats and is capable of rolling on the inner periphery of the outer tube,
• wherein the upper buffer pad is made of soft material and is disposed below the first top plate of the outer tube, wherein the upper buffer pad includes a central portion having a third through-hole through which the inner tube extends, wherein the upper buffer pad further includes an upper face and a lower face, wherein the upper face of the upper buffer pad abuts the first top plate, wherein the lower face of the upper buffer pad abuts the abutting edge of the inner tube when the desk top unit is in a highest position,
• wherein the lower buffer pad is made of soft material and is disposed above the bottom plate of the outer tube, wherein the lower buffer pad includes an upper face and a lower face, wherein the lower face of the lower buffer pad abuts the bottom plate, and wherein the upper face of the lower buffer pad abuts a bottom end of the inner tube when the desk top unit is in a lowest position.
