The utility model relates to the technical field of corrugated pipe production, and provides an expansion corrugated pipe end shaping device which comprises a supporting leg, the top of the supporting leg is fixedly connected with a supporting plate through a screw, the top of the supporting plate is fixedly connected with a mounting frame through a screw, and a lower fixing plate and an upper fixing plate are assembled in the mounting frame in a sliding mode. A detachable positioning plate is mounted at the top of the mounting frame, a fixing air cylinder is mounted at the top of the positioning plate, the upper fixing plate is detachably mounted at the output end of the fixing air cylinder, and the proper upper fixing plate and the proper lower fixing plate are selected according to the size of a corrugated pipe through arrangement of the structures such as the upper fixing plate and the lower fixing plate. And the position of the vertical plate is adjusted to adapt to corrugated pipes of different lengths, and the applicability and flexibility of the device are enhanced.

The utility model discloses a nodular cast iron pipe fitting elbow joint suitable for complex terrains, which comprises an elbow joint, a pipeline, locking rings and a connecting ring, two ends of the elbow joint are respectively connected with the pipeline through the locking rings, and the locking rings are fixed on the elbow joint through mounting sleeves and locking screws. The connecting ring is connected with the connecting rod in a hanging mode through the hanging groove and matched with the connecting sleeve on the pipeline in a clamped mode, and the connecting rod tensions the connecting ring and the locking ring through the adjusting sleeve and the nut so as to achieve rapid locking. The limiting groove is clamped with a clamping rib on the outer side of the connecting sleeve to limit rotation of the connecting ring, a check ring is arranged on the outer side of the connecting sleeve and used for limiting longitudinal sliding of the connecting ring, the two ends of the bent connector are in sealing fit with a sealing ring through clamping rings to improve the sealing performance, and a reinforced fiber layer is embedded in the sealing ring to enhance the pressure resistance. The bent connector is simple in structure and convenient to install, can achieve rapid locking and efficient sealing of the bent connector and a pipeline, meets the use requirements under the complex terrain environment, and solves the problems that a traditional pipe fitting is loose in connection and poor in sealing performance.

The utility model relates to a support system which comprises a base, a rotating device, a clamping device and a fixing piece, a mounting groove is formed in one side of the base and extends in the base in the horizontal direction, the lower end of the rotating device extends into the mounting groove from one side of the base, and the rotating device is installed in the vertical direction. The other end of the rotating device extends out of the mounting groove and is connected with the clamping device; the rotating device and the base are provided with mounting holes matched in the vertical direction, and the fixing pieces are inserted into the mounting holes of the base and the rotating device. The mounting groove is formed in the base, the rotating device in the support system is inserted into the mounting groove in the horizontal direction, then the fixing piece is used for fixing the rotating device to the base in the vertical direction, limiting of the rotating device can be achieved, the mounting process is simple, screw fixing is replaced, and the mounting effect is good.
