Abstract
The utility model discloses a wire extender which is composed of a tensioning plate, a tensioning clamping plate, a pull and push plate and a spring, wherein the tensioning plate is hinged with the tensioning clamping plate hinged with the pull and push plate. The spring is arranged between the pull and push plate and the tensioning plate; the pull and push plate is provided with a convex edge; the tensioning plate is provided with strip-shaped holes; pins on the pull and push plate are arranged in the strip-shaped holes. The utility model has the characteristics of reasonable structure, light weight, small size, flexible operation, portability, etc., and the utility model can be widely used for wire erection or line maintenance in electric power departments, post telephone and telegraph departments, etc.
Description
The utility model relates to a kind of device of clamp.
In post and telecommunications or power department installs electric wiring or during line maintenance, often the tension of two section leads will be connected.This just needs to use clamp and tension equipment.Present employed tension disk complex structure, volume is big, and operation is carried very inconvenient.
The purpose of this utility model provides a kind of tension disk simple in structure, easy to use.
The tension disk that the utility model provides is made up of support brace, tension clamping plate, draw back plate and spring, and support brace is hinged with the tension clamping plate, and tension clamping plate and draw back plate are hinged, and spring is arranged between draw back plate and the support brace; The convex edge is set on the draw back plate, this convex edge can with the tension clamping plate EDGE CONTACT; Support brace is provided with bar hole, is fixing pin on the draw back plate, and this pin is arranged in bar hole.This tension disk is used with strainer.During use, at first compress spring, then lead is placed between the convex edge of strain clamp panel edges and draw back plate; When openhanded open spring after, utilize the elastic force of spring that lead is clamped.Because the tension clamping plate are hinged with support brace and draw back plate respectively, therefore, the strainer tightening force that is connected with tension disk is big more, and the tension disk folder is also big more toward the clamping force of lead.After two section leads were tightened up the device tension and are communicated with, as long as unclamp strainer, tension disk also just eased out naturally.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the schematic diagram of the tension disk that provides of the utility model.
Fig. 2 is the schematic diagram of draw back plate.
Fig. 3 is the cutaway view of Fig. 2 along A-A.
Among the figure, 1, support brace; 2, tension clamping plate; 3, draw back plate; 4, spring; 5, bar hole; 6, pin; 7, convex edge; 8, annulus; 9, teeth.
As shown in Figure 1, this tension disk is made up of support brace 1, tension clamping plate 2, draw back plate 3 and spring 4.Support brace 1 is bar shaped, and the middle part is provided with bar hole 5, and the end is provided with annulus 8, is used to connect strainer.In the present embodiment, tension clamping plate 2 are fan-shaped, and an end and support brace 1 are hinged, and the other end and draw back plate 3 are hinged.The curved edge of tension clamping plate 2 is provided with teeth 9.The effect of teeth 9 is the frictional force when increasing clamp, prevents that lead from skidding off from tension disk.
As shown in Figures 2 and 3, draw back plate 3 is provided with convex edge 7, and convex edge 7 is positioned at the outside of tension clamping plate 2 curved edges.When tension disk is not subjected to external force, is arranged on draw back plate 3 and convex edge 7 is contacted with the teeth 9 of curved edge with spring 4 between the support brace 1.Pin 6 on the draw back plate 3 is arranged in bar hole 5 all the time, but can be movable in bar hole 5.In use, generally need two tension disks and a strainer to be used.
Compared with prior art, the tension disk that provides of the utility model have rational in infrastructure, in light weight, Volume is little, flexible operation and the characteristics such as easy to carry, can be widely used in the departments such as electric power, post and telecommunications.
