Abstract

The utility model provides a device for fastening cables. At present, the cables are generally fastened and fixed by a press plate, the method has the disadvantages of complicated operation and inconvenient maintenance. The device for fastening cables of the utility model comprises a fixed rod, two chain rods, an upper jaw and a lower jaw, wherein, a fixed hole is arranged on the handle of the fixed rod, the two chain rods can be connected with the fixed rod in a rotating way, a gap is arranged between the two chain rods, the upper jaw can be connected with the two chain rods in the rotating way, the lower jaw can also be connected with the two chain rods in the rotating way, and springs causing the upper and the lower jaws to gather are arranged on the two chain rods. The utility model has the advantages of simple operation and convenient disassembly.

Description

Tightener

The utility model relates to a kind of tightener, is used for tension and fixing various cables, for example subway distribution wire, electric car distribution wire etc.

At present, various built on stilts cables all will be strained and be fixed.Present way is: earlier cable is strained, clamped cable with clamping plate or pressing plate again, then clamping plate or pressing plate are fixed on the fixture.The shortcoming stringing process complexity of this stringing device, not easy to operate.In addition, the bolt of clamping jaws gets rusty easily after long-time, carries out dismounting when safeguarding after the inconvenience.

The purpose of this utility model is to provide a kind of easy to operate tightener.

The purpose of this utility model is to realize like this, it comprises a fixing rod, two chain bars, upper jaw and lower jaws, the handle of fixing rod is provided with fixed hole, two chain bars are rotatably connected on the fixed core, and make and have between the two chain bars at interval, upper jaw is rotatably connected on the two chain bars, and lower jaw also is rotatably connected on the two chain bars, and two chain bars are provided with the spring that upper and lower jaw is closed up.

Tightener of the present utility model is work like this, earlier wanting the cable of stringing to put between upper jaw and the lower jaw, the tension cable, upper and lower jaw closes up under the effect of spring then, fixing rod for example is fixed on post, the body of rod, the wall base fixture by the fixed hole on the fixing rod handle again.The characteristics of tightener of the present utility model are, because the deadweight of cable makes the chain bar rotate around the axle that is connected with fixing rod, thereby make upper and lower jaw press tightlyer.When safeguarding, as long as make the chain bar can loosen cable to counter-rotation.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the schematic representation of tightener of the present utility model.

Fig. 2 is the schematic representation of Fig. 1 medium chain bar.

Fig. 3 is the partial sectional view of the chain bar of Fig. 2.

Fig. 4 is the part schematic representation of upper jaw among Fig. 1.

Fig. 5 is the schematic representation of Fig. 1 medi-spring.

See also Fig. 1, tightener of the present utility model comprises fixing rod 1, two

chain bars

2 and 3, upper jaw 4 and lower jaws 5.

Chain bar

2 and 3 is connected on the body of rod of fixing rod 1 by screw 6 and 7, and

chain bar

2 and 3 can rotate around screw 61 and 62 respectively.Be formed with one between the

chain bar

2 and 3 at interval.Lower jaw 5 is connected respectively on

chain bar

2 and 3 by

screw

71 and 72, and upper jaw 4 is connected respectively on

chain bar

2 and 3 by

screw

81 and 82, and upper jaw 4 is above lower jaw 5.On the handle of fixing rod 1, have a fixed hole 11, can be fixed to tightener on the fixture by this hole 11.

See also Fig. 2 and Fig. 3 again, Fig. 2 and Fig. 3 show the structure of chain bar 2 and 3.Because chain bar 2 is identical with 3 structure, so the structure of following only description chain bar 2.The place that connects at chain bar 2 up and down jaws 5 has a trapezoidal hole 21, and has groove 22 on trapezoidal hole 21 limits, and this groove 22 communicates with trapezoidal hole 21.Put into spring 9 as shown in Figure 5 in this trapezoidal hole 21, an Outlet 91 of spring 9 is consistent with the convolute of spring 9, and another Outlet 92 is vertical with convolute.In the time of in the trapezoidal hole 21 of spring 9 being put into chain bar 2, the Outlet 92 of spring 9 extend in the trapezoidal hole 21, and the main body of spring 9 is positioned at the step of trapezoidal hole 21 goes into, and the Outlet 91 of spring 9 is put in the groove 22.This trapezoidal hole 21 also is used to by screw 71 lower jaw 5 is connected on the chain bar 2.The effect of this spring 9 provides the power that upper jaw 4 and lower jaw 5 are closed up.

In order to clamp cable better, on the relative face of upper and

lower jaw

4,5, tooth bar as shown in Figure 4 is set.
