Flexible pipe fixing device with high structure rigidity and high fatigue resistance
2011
The utility model relates to a flexible pipe fixing device with high structure rigidity and high fatigue resistance, which is used for solving the problem that the automobile pipeline fixing device has insufficient rigidity and easily causes fatigue failure and the like. The device is composed of an upper bracket and a lower bracket that are butted with each other; the upper and lower brackets are composed of pipe clamping sections and connecting sections; the pipe clamping sections of the upper and lower brackets are butted in ''8'' shape; the outer ends of the pipe clamping sections of the upper and lower brackets are hinged through a pin shaft; and the connecting sections of the upper and lower brackets are fixedly connected through connecting bolts. The utility model has the following characteristics that: 1, one ends of the pipe clamping sections of the upper and lower brackets are hinged through the pin shaft while the other sides are connected through the bolts, so the defect of ''openings'' of the two sections is well solved; and a certain pre-pressing action is applied to the two flexible pipes so that the pipelines will not be loosened and the two flexible pipes are prevented being dragged out from the device; and 2, the connecting sections of the upper and lower brackets form a closed triangular area so that the device has better stability; and the device solves the phenomenon of stress concentration and has enough strength for preventing the structure causing fatigue failure.
