Abstract

The invention relates to scissors lifting gears, and especially relates to a seat lifting mechanism. The seat lifting mechanism comprises an upper bracket, a lower bracket, a first support bar, a second support bar, an upper sliding block, a lower sliding block and a transmission rod. The transmission rod is fixedly connected to the bottom of the lower bracket, the first support bar and the second support bar are hinged in a center crossing way, the upper end of the first support bar is hinged to the upper bracket, the lower end of the first support bar is hinged to the lower sliding block, the lower sliding block is connected to the lower bracket in a sliding way, the upper end of the second support bar is hinged to the upper sliding block, the lower end of the second support bar is hinged to the lower bracket, the upper sliding block is connected to the upper bracket in a sliding way, the lower sliding block comprises a lower bracket connection portion and a transmission rod connection portion, the lower bracket connection portion is connected to the lower bracket in a sliding way, the transmission rod is provided with a transmission part, and the transmission part is used for connecting the transmission rod connection portion to the transmission rod in a sliding way. The accurate vertical adjustment can be guaranteed, the lifting height range is great, and the reliable stiffness and bearing capacity are guaranteed.

Description

technical field [0001] The invention relates to a scissor lifting device, in particular to a seat lifting mechanism. Background technique [0002] The seat lifting mechanism in the current man-machine test bench adopts a planar linkage mechanism, a screw guide column mechanism or a hydraulic ejector mechanism. The plane link mechanism has the problem of not being able to adjust vertically, the screw guide column mechanism has the problem of too small stroke and insufficient carrying capacity, and the hydraulic ejector mechanism has the problem of inaccurate position adjustment. Contents of the invention [0003] The invention provides a seat lifting mechanism, which aims to solve the problems of small stroke, insufficient carrying capacity, inaccurate position adjustment and the like in the existing lifting mechanism. [0004] The invention provides a seat lifting mechanism, which includes an upper support, a lower support, a first support rod, a second support rod, an up...
