An object of the utility model is to provide a high tension transmission line prevents device that splits to prior art not enough.

In order to achieve the above purpose, the present invention is achieved by the following technical solutions.

The utility model provides a high tension transmission line anti-fracture device, it includes drum, cassette tape, strengthening rib, hose clamp, the both ends of drum are provided with the cassette tape respectively, and the cassette tape of homonymy is two, and two relative settings of cassette tape, the strengthening rib sets up in drum, cassette tape, the hose clamp is equipped with on the drum, cassette tape, strengthening rib integrated into one piece.

Further, drum, cassette are the preparation of PVC material, set up a plurality of beaded finish in the drum, weld as an organic whole between beaded finish and the strengthening rib.

Furthermore, the cross-section of cassette is crescent, evenly be provided with eight strengthening ribs in the cassette.

Furthermore, a bulge is arranged on the top surface of the clamping belt and along the central axis direction of the cylinder, and convex teeth are arranged on the bottom surface of the clamping belt and along the radial direction of the cylinder.

Furthermore, the reinforcing ribs are made of reinforcing steel bars, and a plurality of spurs are arranged in the middle of the reinforcing ribs at equal intervals.

Furthermore, the hose clamp is made of PVC materials, and the number of the hose clamp is at least 4.

The utility model has the advantages that: this novel electric wire anti-breaking device can strengthen the intensity of cable junction department, and the stretching resistance of reinforcing electric wire prevents the fracture of electric wire in the junction.

Detailed Description

The present invention is further illustrated by the following examples, but is not limited to the contents of the specification.

As shown in the figure: the utility model provides a high tension transmission line anti-fracture device, it includes drum 1, cassette 2, strengthening rib 3, throat hoop 4, and the both ends of drum 1 are provided with cassette 2 respectively, and the cassette 2 of homonymy is two, and two relative settings of cassette 2, strengthening rib 3 set up in drum 1, cassette 2, and the cover is equipped with throat hoop 4 on the drum 1,

cassette

2, 3 integrated into one piece of strengthening rib.

Drum 1, cassette 2 is the preparation of PVC material, insulating non-conducting, corrosion resistance can be good, drum 1 mainly plays the effect of sharing the electric wire pulling force of bearing, its inside is provided with strengthening rib 3, further strengthen drum 1's intensity, be convenient for bear bigger pulling force, cassette 2's cross-section is crescent, even being provided with eight strengthening ribs 3 in the cassette 2, on the top surface of cassette 2 and be provided with arch 21 along drum 1's axis direction, be convenient for when 4 joints of larynx hoop are on cassette 2, can increase the frictional force between 4 and the cassette 2 of larynx hoop, edge and drum 1's radial direction is provided with dogtooth 22 on the bottom surface of cassette 2, pass drum 1 at the electric wire like this, when using 4 joint cassette 2 of larynx hoop, the frictional force between multiplicable cassette 2 and the electric wire, prevent the electric wire slippage under the pulling force effect.

The strengthening rib 3 is eight, and strengthening rib 3 adopts the reinforcing bar preparation, sets up in drum 1, cassette 2, for further reinforcing strengthening rib 3 and drum 1 between joint strength, can be in the equidistant a plurality of that sets up of strengthening rib 3 spurs 31 in the middle part, simultaneously, in order to strengthen strengthening rib 3's intensity, can set up a plurality of beaded finish 32 in drum 1, welds as an organic wholely between beaded finish 32 and the strengthening rib 3.

The hose clamp 4 is an existing hose clamp made of PVC materials and is good in insulating performance. The number of the throat hoops 4 is at least 4, so that two hoops can be respectively used on the clamping bands 2 at two sides of the cylinder 1, and the use strength is enhanced.

This neotype theory of use: before two high-voltage wires are connected, the high-voltage wires firstly penetrate through the cylinder, then two cables are connected, after the connection, the cylinder is moved, the joint part is located in the cylinder, then the hose clamp is moved to the clamp belts on the two sides of the cylinder, the hose clamp is clamped, the clamp belts are tightly attached to the cables, the purpose that the tensile force of the wires is shared by the cylinder is achieved, and the cables are prevented from being broken at the connection position.
