Detailed Implementation
[0023] The present invention will now be described in further detail with reference to the accompanying drawings.
[0024] like Figure 2 , Figure 3 As shown, this utility model includes a rotating support 2, a clamp 4, and a connecting rod 5. There are two connecting rods 5, one end of each connecting rod 5 is hinged to the rotating support 2, and the other ends of the two connecting rods 5 are hinged together. The rotating support 2 hinged to one connecting rod 5 is fixed on the equipment 10, and the rotating support 2 hinged to the other connecting rod 5 is fixed on the aircraft structure 11. A clamp 4 is fixedly connected to each connecting rod 5.
[0025] The rotating support 2 primarily serves to fix the entire device to the equipment 10 or aircraft structure 11, and provides a rotation axis for the connecting rod 5 via bolts B12 and nuts 3, while limiting the rotation range of the connecting rod 5 via grooves 15. Figures 2 to 5 As shown, the rotating support 2 in this embodiment has a groove 15. The groove width of the end of the groove 15 near the device 10 or aircraft structure 11 is greater than the groove width of the other end near the connecting rod 5. One end of the connecting rod 5 is inserted from the end with the smaller groove width. The rotating support 2 has four connecting holes A14, with two connecting holes A14 at each end. The two connecting holes A14 at one end are located at the bottom of the groove 15, and the two connecting holes A14 at the other end are symmetrically located on both sides of the groove 15. The rotating support 2 is connected to the device 10 or aircraft structure 11 via a bolt A1 passing through a connecting hole A14 at one end. The device 10 or aircraft structure 11 can use a nut 3 or directly drill internal threads; no limitation is made here. In this embodiment, both ends of the connecting rod 5 have connecting holes B18. One end of the connecting rod 5 is inserted into the groove 15. The connecting rod 5 and the rotating support 2 are hinged together by a bolt B12 passing through the connecting hole A14 at the other end of the rotating support 2 and the connecting hole B18 at one end of the connecting rod 5, and a nut 3 threadedly connected to the bolt B12. The groove 15 is used to restrict the movement space of the connecting rod 5. The other end of the connecting rod 5 is hinged together by a locking bolt 6 passing through the connecting hole B18 at the other end and a locking nut 7 threadedly connected to the locking bolt 6, and another connecting rod 5.
[0026] The one side of the connecting rod 5 of the embodiment extends outwardly to form an extension 16, and a clamp mounting hole 17 is formed in the extension 16; the clamp 4 used for wiring harness laying is fixed to the connecting rod 5 through the bolt C13 passing through the clamp mounting hole 17 and the nut 3 and the bolt C13 threadedly connected.
[0027] The working principle of the utility model is as follows:
[0028] As shown in Figure 6 the utility model fixes the excess wiring harness 8 through two rotating supports 2 fixing the whole device and the equipment 10 and the aircraft structure 11 respectively and forming a two-connecting-rod mechanism with the connecting rod 5, drives the rotating support 2 at one end of the device to move along with the equipment dismounting or mounting, then drives the connecting rod 5 and the excess wiring harness 8 fixed thereon through the clamp 4 to move together.
[0029] As shown in Figure 7 when the equipment 10 is installed in place, the positions of the rotating supports 2 at both ends of the device are fixed, the connecting rod 5 is also locked by the rotating shaft composed of the groove 15 of the rotating support 2 and the bolt B12, the nut 3 and the counter-lock bolt 6 and the counter-lock nut 7, so that the excess wiring harness 8 is fixed, and shaking is avoided.
