STRUCTURE THAT HIGH AND LOW IS REGULATED AUTOMATICALLY

摘要

This invention relates to automatic height adjustment mechanism, more specifically a lever insertion hole is formed foot, support shaft insertion hole and the arm insertion hole is comprised of the box, control box, motor, distributing evenly around the rotational force in the longitudinal direction by the motor gear, the left and right front and rear gear to evenly distribute the rotary force in the lateral direction of the gear, is passed under the rotating force of the left and right end gear fixed to the shaft groove is formed and the male screw shaft is formed on the outer surface of male screw acid, the fit pin is protruded and the axial outer surface of the male screw thread the female screw member disposed, the roll bearing is fitted on the fitting pin wheels, a lower one is on the other end of the upper and lower end of the lever to move the lever as shown in the upper-fit pin fitting and the other end is inserted into the fitting pin to roll the wheel bearing and pin fitting to obtain the intermediate lever arm insertion hole of the base box characterized by comprising a pin fitting arm, sinks, desks, closet heavy elevator without the need to balance each leg for supporting a load, such as easy, fine length that is easy to adjust the load of the upper unit This not only can it be easily adjusted even when the larger, by an electric automatically has the effect that can be implemented at any time the sense of modern design for the adjustable height as that according to the human body or taste.
