Canvas flexible joint

The invention discloses a canvas flexible joint. The canvas flexible joint is characterized in that the canvas flexible joint is arranged between two flanged joints and comprises canvas which is of a long strip shape, a left connector and a right connector which are arranged on two ends of the canvas, wherein the left connector is as same as the right connector, the left connector and the right connector are arranged symmetrically, the left connector penetrates through a steel plate and is connected to a bolt on the corresponding flange joint through the steel plate arranged opposite to the corresponding flange joint, one end of the canvas is arranged on the steel plate and the corresponding flange joint, and the bolt penetrates through one end of the canvas. Due to good connection performance and tenacity of the canvas, canvas connection is adopted, and therefore, the requirements of using in complex occasions are met. In addition, galvanization mild steel plates are adhered to the two ends of the canvas, strength of end portions is strengthened, and requirements of using in occasions with high-strength connection are met.
