Abstract

The utility model relates to a device for causing wires to penetrating pipes for electricians, which comprises a conducting wire 1 and conducting heads 2 fixed on both ends of the conducting wire 1, wherein, each conducting head 2 is provided with a transverse through hole 3 and a tip 4. An electric wire to penetrate an electric wire pipe can be penetrated in the hole 3, and the conducting head on the other end can be gradually transferred to the electric wire pipe. The conducting head extends out from the other end of the electric wire pipe. The electric wire can be penetrated in the electric wire pipe after the conducting head is drawn out. A large quantity of construction cost and time can be saved by using the tool for penetrating wires.

Description

Electrician's pipe perforator

The utility model relates to hand tools, particularly other class fastening, connection, dismounting or clamping tools of being used for not to be covered.

At present, in construction and maintenance work, giving that laying wire is very difficult thing in the conduit that buries, generally be when the reason conduit is given in construction, in pipe, to put on iron wire, treat that civil engineering finishes, iron wire one end is fastened electric wire, iron wire is pulled out and electric wire is laid on the conduit from the other end.How long this construction method has pipeline how long must bury iron wire, and the iron wire waste is very big, wears iron wire just in case leak, and will take a lot of times then wear the work of electric wire, and very difficult, and waste also very big man-hour.

The purpose of this utility model provides a kind of electrician's pipe perforator that can draw electric wire by conduit easily.

The purpose of this utility model realizes by following technical scheme, electrician's pipe perforator comprises a lead and is fixed on the top guide at these lead two ends, has a horizontal through hole on the top guide, in this through hole, penetrate the electric wire of desiring to penetrate in the pipe, and send into another top guide in the conduit gradually, when top guide when the conduit other end stretches out, pipe perforator can be pulled out, can be with in the electric wire lead-in tube.

Below in conjunction with drawings and Examples electrician's pipe perforator of the present utility model is explained in detail.

Fig. 1 is the structure chart of the utility model electrician pipe perforator;

Fig. 2 is the structural representation of the top guide of this electrician pipe perforator;

Fig. 3 is the schematic diagram of another kind of structure of the top guide of this electrician pipe perforator.

As Fig. 1, electrician's pipe perforator has a long lead 1, the two ends of lead 1 all are fixed with a metal top guide 2, has a horizontal through hole 3 on the top guide 2, the size in hole should be able to penetrate desires to draw the electric wire that penetrates in the conduit, said lead 1 is made of plastics, as polypropylene plastics, it has enough intensity, elasticity and resistance to wear, big outer little hole 5 or have the hole 6 of a step in top guide 2 can be made with the connecting hole of lead 1, as Fig. 2 or Fig. 3, when the plastic wire heating is made it to soften and press in this hole, cooling back plastic wire 1 can be solidly installed with top guide 2, there is a tip 4 end of top guide, so that pass pipe smoothly, the gabarit of top guide can be made into six cylinders, so that enough spaces are arranged around in pipe the time, be convenient to turn round and some slag ashes are passed through, the diameter of lead 1 is decided on the electric wire worn and the diameter of conduit, for general residential electric power line, and the about 3-6mm of the diameter of lead 1.Length is then decided on demand.

During use, at first an end of pipe perforator is sent into the conduit of desiring to penetrate electric wire, because plastic wire has certain rigidity and flexible, so be easy to penetrate, also be easy to even turn round by, after stretch out from the other end end, the electric wire of desiring to penetrate is penetrated in the hole 3 of top guide and pipe perforator is pulled out from the other end, electric wire can penetrate conduit.

Electrician's pipe perforator of the present utility model, easy to use, can save a large amount of iron wires, and save and give this operation of burying iron wire, can save operating expenses greatly, because the toughness and the smooth degree of lead 1 is all strong far beyond iron wire, so the work of penetrating is saved time, easily very much.

Claims
