Abstract:
1. A hose frame assembly comprising: a pipe body comprising three pipe sections in an end to end connection, and two resilient joints connected between every adjacent two of the three pipe sections; a wheel disc; a tensile adjusting device located between the pipe body and the wheel disc, and comprising a guide rail, two sliding members slidably mounted to the guide rail, and a resilient member connected between the sliding members, wherein a wheel is rotatably mounted to each of the sliding members; and a cable comprising two ends, wherein the ends of the cable extend through the pipe sections and the resilient joints and are spacedly fixed to an inner wall of one of the pipe sections located at a far end of the pipe body, a portion of the cable located out of the pipe body is positioned around the wheel disc and the wheels; wherein the wheel disc is rotated to distort the cable, thus shortening and lengthening two segments of the cable partitioned by the wheel disc, thereby forming a shortened segment and a lengthened segment simultaneously, and the pipe body curves along the side of the shortened segment, the resilient member pushes the wheel at the side of the lengthened segment to move towards the lengthened segment to maintain tension on the lengthened segment.
