A weldable elastic hanger plate device for preventing the yaw of an involute toothed chain

Abstract

The application relates to a weldable elastic hanging plate device for preventing the yaw of an involute toothed chain, which comprises a backrest frame and a seat frame, the backrest frame is installed on the seat frame, backrest frame guide rails are arranged on the two sides of the backrest frame, seat frame guide rails are arranged on the two sides of the seat frame, a toothed chain is connected between the backrest frame guide rails and the seat frame guide rails, the backrest frame is erected or laid on the seat frame to make the toothed chain bend or stop bending, the bottom of the toothed chain is provided with an elastic hanging plate, one end of the elastic hanging plate is fixed on the backrest frame guide rail, and the other end of the elastic hanging plate is fixed on the seat frame guide rail, the toothed chain comprises a plurality of chain tooth plates, the elastic hanging plate is fixedly connected with the chain tooth plates and longitudinally bends synchronously with the toothed chain when the toothed chain bends. The device has the advantages of longitudinal bendability and good anti-shaking performance in the transverse direction of the toothed chain.
