Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
the first embodiment is as follows:
as shown in fig. 1, the utility model provides a pair of wire harness restraint device, including pencil 1, in order to avoid other parts on the route that pencil 1 arranged, need bend one of them segment pencil 1, first fastener 2 and second fastener 3 are fixed respectively at the both ends of the pencil section that needs bend, connect length adjustment mechanism between first fastener 2 and the second fastener 3, utilize length adjustment mechanism to adjust the distance between first fastener 2 and the second fastener 3, and then can drive the crooked or tensioning of pencil 1 between first fastener 2 and the second fastener 3, with the radian of adjusting the pencil section and the position of bending, reach the design objective.
In this embodiment, the length adjustment mechanism is composed of a first screw rod 4, a second screw rod 5 and a thread sleeve 6, the first wire clamp 2 is movably connected with the first screw rod 4, the second wire clamp 3 is movably connected with the second screw rod 5, preferably, the first wire clamp and the second wire clamp are connected in a hinged manner, and the first screw rod 4 is connected with the second screw rod 5 through the hexagonal thread sleeve 6. The first screw rod 4 and the second screw rod 5 are opposite in rotation direction after being installed, and the extension or the shortening of the first screw rod 4 and the second screw rod 5 can be adjusted according to requirements by rotating the hexagonal thread sleeve 6 in the middle through a wrench, so that the adjustment of the distance between the two wire clamps 1 is realized.
The first wire clamp 2 and the second wire clamp 3 have the same structure and are composed of a first wire clamp body and a second wire clamp body (not marked in the figure) which are fixedly connected together in a mutually buckled mode, and the first wire clamp body and the second wire clamp body are fixedly connected together through a bolt 7. The corresponding half recess that is used for holding pencil 1 that is provided with on first wire clamp body and second wire clamp body, first wire clamp body and second wire clamp body lock back press from both sides the tight centre with pencil 1. The number of the half grooves may be designed according to the number of the wire harnesses 1, and may be one or a plurality of side-by-side grooves. When only one wiring harness 1 needs to be bent, the wiring harness can be fixed only by the wire clamp 1 provided with only one pair of half grooves, and when a plurality of wiring harnesses 1 arranged side by side need to be bent simultaneously, the wire clamp 1 provided with the half grooves in corresponding quantity can be selected to fix the wiring harness.
