Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Embodiment one: a kind of transmission line jumper clamp forming transmission line for connecting wire 9, comprise flute profile drainage plate 1, ligulate drainage plate 2 and pressing plate 3 three parts, wherein flute profile drainage plate 1 and ligulate drainage plate 2 are connected to a wire 9, and these two wires 9 realize by this transmission line jumper clamp connecting.
As shown in accompanying drawing 1 to accompanying drawing 3, flute profile drainage plate 1 main body is cuboid, and it comprises relative upper surface and lower surface and four sides being connected upper surface and lower surface.The upper surface of flute profile drainage plate 1 offers a groove 4, the length direction amplification of this groove 4 forms side mouth to a side.On another side relative with that side with side mouth, be provided with a junction block 8, by this junction block 8, flute profile drainage plate 1 connects a wire 9.In the both sides of groove 4, offer two bolts hole 7 respectively.
As shown in accompanying drawing 4 to accompanying drawing 6, the profile of the groove 4 that the main body of ligulate drainage plate 2 and flute profile drainage plate 1 are offered matches, and the thickness of ligulate drainage plate 2 is then identical with the degree of depth of the groove 4 on flute profile drainage plate 1.One end of ligulate drainage plate 2 is also provided with a junction block 8, and by this junction block 8, ligulate drainage plate 2 connects another root wire 9.
As shown in accompanying drawing 7 to accompanying drawing 9, pressing plate 3 is in cuboid, and on it, four bolts hole 7 corresponded on flute profile drainage plate 1 also offer the bolt hole 7 of same size.
As shown in Figure 10, the mounting means of this transmission line jumper clamp is as follows: embedded by ligulate drainage plate 2 in the groove 4 on flute profile drainage plate 1, and the junction block 8 that an end of ligulate drainage plate 2 connects and wire 9 are then stretched out outside flute profile drainage plate 1 by side mouth.Because the degree of depth of the groove 4 on flute profile drainage plate 1 is identical with the thickness of ligulate drainage plate 2, so embedded by ligulate drainage plate 2 after in the groove 4 on flute profile drainage plate 1, the two forms a concordant outer surface.Pressing plate 3 is covered on flute profile drainage plate 1 and ligulate drainage plate 2, make the bolt hole 7 on pressing plate 3 and the bolt hole 7 on flute profile drainage plate 1 corresponding, pressing plate 3 and flute profile drainage plate 1 are fixedly connected by the bolt (not shown) again by matching with bolt hole 7, and are anchored between pressing plate 3 and flute profile drainage plate 1 by ligulate drainage plate 2.
Can not skid off by groove 4 in order to ensure ligulate drainage plate 2, between flute profile drainage plate 1 and ligulate drainage plate 2, be provided with position-limit mechanism.Position-limit mechanism comprises the stopper slot 5 of the indent be arranged in groove 4 and is arranged at positive stop strip 6, the shape of stopper slot 5 and the mating shapes of positive stop strip 6 of the evagination on ligulate drainage plate 2.Such as, stopper slot 5 is arranged at the end of groove 4, positive stop strip 6 is arranged at the end of ligulate drainage plate 2, and the axis direction of wire 9 that the length direction of the length direction of stopper slot 5, positive stop strip 6 is all connected with flute profile drainage plate 1 and ligulate drainage plate 2 is perpendicular, the cross section of stopper slot 5 and the cross section of positive stop strip 6 are arc.When in the groove 4 that ligulate drainage plate 2 embeds flute profile drainage plate 1, positive stop strip 6 snaps in stopper slot 5 and stops ligulate drainage plate 2 to skid off groove 4 along wire 9 length direction.
Above-mentioned wire clamp can avoid wire 9 directly to produce pulling force by flute profile drainage plate 1, ligulate drainage plate 2 pairs of bolts.In addition the thickness of ligulate drainage plate 2 and the groove 4 of flute profile drainage plate 1 consistent, after pressing plate 3 is fixing, too increases the water conservancy diversion cross section of wire clamp, thus improve drainage effect.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection range of the present utility model.
