Abstract
The invention discloses pin-shaft-middle-double-face-planed hinged connection. The pin-shaft-middle-double-face-planed hinged connection comprises a mono-lug seat, a pin shaft, a dual-lug seat, screws and the like. According to the pin-shaft-middle-double-face-planed hinged connection, a pin shaft hinged connection mode which is universally adopted in the mounting and connecting of products currently is improved, and the pin shaft is enabled to only penetrate through a pair of dual-lug seat pin shaft holes and then enabled to be fixedly connected with the mono-lug seat through the screws; screw holes in the pin shaft are unthreaded holes and can be bigger, so that the screws can be more easily screwed into a mono-lug seat screw hole through the screw holes of the pin shaft, and required rotatable connection between the mono-lug seat and the dual-lug seat can be completely formed after the screws are screwed; the remarkable increase of difficulty of mounting in the prior art due to the fact that the pin shaft needs to simultaneously penetrate through all three pin holes of the dual-lug seat and the mono-lug seat, particularly when relatively-high-accuracy movable fit exists between the pin shaft and the pin holes and both the volume and weight of connected workpieces and the pin shaft are high is avoided.
