CN205248710U - Threading equipment - Google Patents

Abstract

The utility model provides a threading equipment, includes pipeline and electric wire, the both ends of pipeline are inlet wire end and leading -out terminal respectively, and the tip fixed seal of electric wire encircles, and the sealing ring is established in inlet wire end the inside, the sealed fixed air compressor of leading -out terminal. The beneficial effects of the utility model are that: compared with the prior art, the utility model discloses utilize the atmospheric pressure difference of sealing ring both sides, in channel bend department, atmospheric pressure difference is unanimous basically with the axial of pipeline to the pressure of sealing ring, so the electric wire is more easily through the elbow, the less construction degree of difficulty has improved the efficiency of construction.

Description

A kind of threading device

Technical field

The utility model relates to electric wire construction equipment, particularly a kind of threading device.

Background technology

The raising of producing along with life now, relies on more and more stronger to power supply, network etc. The line body major parts such as electric wire are layered on lowly, are generally first tubings, then electric wire etc. is passed and gone from pipeline. And present threading method is for first pass through an iron wire in pipeline, fix one end of online body with one end of iron wire, the then other end of bracing wire, drives electric wire through pipeline, completes threading. But if pipeline is bending, in elbow, the pulling force of iron wire and the axis of pipeline have angle, so be not easy to pass through constructional difficulties.

Utility model content

For overcoming above-mentioned deficiency, the purpose of this utility model is to provide a kind of easily by the threading device of channel bend.

The technical solution of the utility model is specially:

A kind of threading device, comprises pipeline and electric wire, and the two ends of described pipeline are respectively end of incoming cables and leading-out terminal, the end fixing seal ring of electric wire, and sealing ring is located at the inside, end of incoming cables, leading-out terminal sealing fixed air compressor.

Two sealing rings are fixed in the end of electric wire.

The end of electric wire is sharp portion.

The beneficial effects of the utility model are: compared to the prior art, the utility model utilizes the draught head of sealing ring both sides, at channel bend place, the pressure of draught head to sealing ring and pipeline axially basically identical, so, electric wire is more easily by elbow, and less difficulty of construction, has improved efficiency of construction.

Brief description of the drawings

Fig. 1 is schematic diagram of the present utility model.

Detailed description of the invention

As Fig. 1, a kind of threading device, comprises pipeline 1 and electric wire 2, and the two ends of pipeline 1 are respectively end of incoming cables 11 and leading-out terminal 12, the end fixing seal ring 21 of electric wire 2, and sealing ring 21 is located at 11 the insides, end of incoming cables, and leading-out terminal 12 seals fixed air compressor 3.

Two sealing rings 21 are fixed in the end of electric wire 2, can play the effect of similar ship lock, better effects if.

The end of electric wire 2 is sharp portion, more easily passes through pipeline.

Operation principle is:

After this equipment is installed, open the switch of air compressor, because the pipe section between sealing ring and air compressor is sealed chamber, so the air pressure in this section of tubing can reduce and be negative pressure, and the air pressure of the end of incoming cables in sealing ring outside is normal atmosphere (An), there is in other words draught head in sealing ring both sides, utilize this draught head, can make the leading-out terminal motion of electric wire (together with sealing ring) to pipeline, complete threading.

Other guide is shown in prior art.
