Abstract
The utility model relates to an iron wire quick -operation joint divide into long joint and short circuit head, and two connect and to form spindle -shaped cavity inner chamber through screwing member, cylindrical cavity and both sides and the communicating toper cavity of cylindrical cavity in the middle of this cavity inner chamber divide into, and the diameter of cavity inner chamber is 3.0~3.5 times of the iron wire diameter, and the diameter in funnel neck chamber is 1.1~1.5 times of iron wire diameter in the toper cavity, adopt this joints when wearing the cable in the steel pipe and since the iron wire head bend, buckle each other come after at the in -process of pulling, the inner wall and the iron wire that connect the cylinder inner chamber can produce huge extrusion force near being in the same place to throwing off of iron wire joint prevent effectively. Consequently, compare with prior art, the utility model provides an iron wire quick -operation joint is because the structure is unique reasonable, and can relax swiftly couples the iron wire, has improved work efficiency, and the pulling force that bears can be up to 2500N, needs when satisfying the cable threading, difficult emergence drops.
Description
Technical field
This utility model relates to field of cable technology, be specifically related to a kind of for wearing cable in steel pipe time the joint of lead-in wire iron wire, it is easy and simple to handle, holding capacity greatly, not easily disengage.
Background technology
At present, kelvin effect heat tracing technology is as a kind of new metallic conduit heating means occurred in recent years, it is the new technique of enterprise's Heated pipeline heating and thermal insulation, the new technologies such as large-scale petroleum chemical industry, there is efficiency height, adapt to all long, medium and short distances and can belong to heat tracing and the heating of liquid-transport pipe-line, the advantage such as safe and reliable, convenient to install and maintain, is therefore widely used in the pipeline transportation of various liquid of different nature.
The actual application of this technology need by cable traverse steel pipe, generally iron wire is set at the two ends of steel pipe and cable, iron wire head bends when wearing cable in steel pipe, mutually buckles, thus completing the connection of lead-in wire iron wire, iron wire is then pulled to make cable traverse steel pipe.In prior art, one section of sleeve pipe can be selected between two steel pipes to be attached, owing to the external diameter of sleeve pipe is slightly larger than steel pipe, thus causing injustice in pipe to define a step surface, existence due to this step surface, the irregular contour of iron wire joint is easily hung in pipe step place thus splice failure so that worn cable must not retreat；Simultaneously; the pulling force that existing iron wire joint can bear after simply coupling is limited; can only achieve 880N; even if also can only achieve 1200N after the coated insulation adhesive plaster of joint; owing to the heat pipe in whole collection skin system is very long and there is many expansion bends; therefore when iron wire draws, cable length below is slightly long or after several pipelines are turned, pulling force is just not enough to the cable affected below, often disengages in joint；Current solution is that iron wire twists into the pulling force that twisted shape can bear with increase, but the method is relatively cumbersome, greatly reduces work efficiency.
Utility model content
The purpose of this utility model is aiming at above-mentioned deficiency of the prior art, a kind of iron wire snap joint rational in infrastructure, easy and simple to handle is provided, the joint of the iron wire that goes between when it is mainly used in wearing cable in steel pipe, bigger pulling force can be born so that during lead-in wire, iron wire can quickly couple and not easily disengage.
To achieve these goals, the technical solution of the utility model is as described below:
A kind of iron wire snap joint, it is divided into lengthening joint and short circuit head two parts, described lengthening joint and short circuit head all include a cylindrical cavity and a cone-shaped cavity, lengthening joint and short circuit head can be flexibly connected so that form the hollow cavity of fusiformis after two cylindrical cavity docking, the diameter of this hollow cavity is 3.0～3.5 times of iron wire diameter, it is preferred to about 3.1 times；
The internal cavities of described cone-shaped cavity is funnel-form, and it is divided into filler neck chamber and funnel oral cavity, wherein filler neck chamber cylindrical and its diameter is iron wire diameter 1.1～1.5 times, it is preferably about 1.2 times, the little oral area in funnel oral cavity communicates with filler neck chamber, and the big oral area in funnel oral cavity communicates with cylindrical cavity；
Described flexible connection preferably employs threaded.
Iron wire snap joint provided by the utility model is divided into lengthening joint and short circuit head, two joints are threaded connection one shuttle shape structure of formation, and hollow cavity is divided into the cone-shaped cavity that middle cylindrical cavity and both sides communicate with cylindrical cavity, wherein, the diameter of hollow cavity is 3.0～3.5 times of iron wire diameter, being preferably about 3.1 times, in cone-shaped cavity, the diameter in filler neck chamber is 1.1～1.5 times of iron wire diameter, it is preferred to about 1.2 times；Above-mentioned each structure effect of cooperating, one each other, ensure that when wearing cable in steel pipe, adopt this joint simple and efficient and not easily disengage, after bending due to iron wire head, mutually buckle in the process pulled, the inwall of joint cylindrical cavity and iron wire are closely packed together, and can produce huge extruding force, thus effectively stoping the disengagement of iron wire joint.Therefore, compared with prior art, iron wire snap joint provided by the utility model is due to structure uniqueness rationally, it is possible to is relaxedly and rapidly coupled by iron wire, improves work efficiency；And bear bigger pulling force so that joint is firmly connected, it is not easy to fall off.

Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
A kind of iron wire snap joint 10, it is divided into lengthening joint 1 and short circuit head 2 two parts, described lengthening joint 1 and short circuit head 2 all include a cylindrical cavity 4 and a cone-shaped cavity 5, lengthening joint 1 and short circuit head 2 are threaded connection parts 3 and connect so that form the hollow cavity of fusiformis after two cylindrical cavity 4 docking, the diameter of this hollow cavity is 3.0～3.5 times of iron wire diameter, it is preferred to about 3.1 times；
The internal cavities of described cone-shaped cavity 5 is funnel-form, and it is divided into filler neck chamber 6 and funnel oral cavity 7, wherein filler neck chamber 6 cylindrical and its diameter is iron wire diameter 1.1～1.5 times, it is preferably about 1.2 times, the little oral area in funnel oral cavity 7 communicates with filler neck chamber 6, and the big oral area in funnel oral cavity 7 communicates with cylindrical cavity 4.
During use, the prefabricated iron wire of difference on steel pipe and cable, steel pipe iron wire 8 is passed into funnel oral cavity 7 from the filler neck chamber 6 of lengthening joint 1, cable iron wire 9 is passed into funnel oral cavity 7 from the filler neck chamber 6 of short circuit head 2, steel pipe iron wire 8 and cable iron wire 9 are bended on iron wire head and mutually buckle, then utilizes threaded connection element 3 by threaded to lengthening joint 1 and short circuit head 2.After completing above-mentioned each operation, the other end at steel pipe pulls iron wire so that cable is traverse steel pipe under the affecting that iron wire goes between.
