Abstract

The invention provides a linkage mechanism, and relates to the structure improvement of the linkage mechanism. The linkage mechanism is simple in structure, low in production cost, sensitive in response and high in linkage precision. The linkage mechanism comprises a machine frame, an outer plate, a guide rail, a vertical guide pillar, an inner frame, an inner frame groove, a connecting plate, a gasket, a pin shaft, a rocker arm, a connector, an upper shaft, a scissor bracket, a bracket base, a bracket shaft, a rotating center and a rotating shaft. The linkage mechanism is characterized in that the machine frame is externally provided with the outer plate which is internally provided with the inner frame, the inner frame groove is arranged on the upper portion of the inner frame, and the rocker arm is arranged between the inner frame and the outer plate, and the machine frame; the lower end of the rocker arm is connected with the inner frame groove, the inner frame and the outer plate through the gasket and the pin shaft, and the upper end of the rocker arm is provided with the connector; the lower end of the inner frame is provided with the connecting plate, the lower portion of the connecting plate is provided with the scissor bracket through the bracket shaft, the lower end of the scissor bracket is provided with the rotating shaft and the lower end of the bracket shaft is provided with the bracket base.

Description

technical field [0001] The invention relates to an improvement of a linkage mechanism structure. Background technique [0002] At present, the existing lifting linkage system has disadvantages such as complex structure, high production cost, insensitive response, and low linkage precision.
