Conventionally, when introducing and pushing a call line into a pipe, or connecting a wired material such as a cable to a connecting fitting and pulling it into a pipe, long lengths made of thermoplastic resin were used to pull the wire with a large tensile force. The main part of the call line, which consists of a linear body of
Alternatively, there was a problem that the surface could be damaged by rubbing against obstacles such as stepped parts or joints in the pipe. Furthermore, during the introduction process, the presence of the sharp bends and obstructions increases sliding resistance due to contact with these parts, making it difficult to initially push the call line into the pipe.

The fine oil droplets contained in the thermoplastic resin, especially in the surface layer, seep out to the surface and become covered with a molecular film or a thin film close to this, so the surface of the main wire is present inside the pipe. There is no direct contact with obstacles or the inner circumferential surface of the pipe. Therefore, sliding friction is significantly reduced and wear of the main wire main surface is prevented.

る。 Next, to briefly explain the oil-impregnated plastic composition that can be adopted as the above-mentioned oil-impregnated thermoplastic resin which is the constituent material of the main body 2, lubricating oil is added to ultra-high molecular weight polyethylene having an average molecular weight of 500,000 or more. Examples include oleoplastic compositions obtained by adding the mixture to a mixture of one or more thermoplastic resins. In this case, the lubricating oil may be a synthetic lubricating oil such as machine oil, gear oil, or petroleum-based lubricating oil. It is also desirable to add solid fillers consisting of fibrous materials such as natural or artificial fiber strips and powders of gold steel, aluminum, etc. to the composition to increase its mechanical strength. The above-mentioned oil-impregnated plastic composition has a lubricating oil added with the help of ultra-high molecular weight polyethylene, can be subjected to extrusion molding, etc., and has no decrease in mechanical strength. Furthermore, it has greater wear resistance than general synthetic resins. In addition, as a carrier for holding oil in the base thermoplastic resin, it simultaneously contains two types: a powder made of polyolefin (polyethylene, polypropylene, polybutylene) and an inorganic powder such as activated carbon or diatomaceous earth, and as a lubricating oil. The oil-impregnated plastic composition may contain polyolefins having a high swelling property and a polyolefin having a small swelling property. The reason why two types of carriers were used as described above is that if the amount of polyolefin added increases too much, the strength will decrease, and even if the content increases, the wear resistance will not improve proportionally. Addition of activated carbon, diatomaceous earth, etc. increases the oil content and improves the wear resistance, but if the amount added is too large, the wear resistance is adversely affected.

ことができる。 Another method of obtaining the oleoreplastic composition is to add lubricating oil and activated carbon to a thermoplastic resin, preferably at a lubricating oil to activated carbon ratio of 3.5.
cc/cc or less, and may be melt-kneaded using an extruder having two or more screw shafts to stably extrude mold. According to this production method, it is possible to obtain an inexpensive oil-impregnated plastic composition that has excellent wear resistance under high loads and high speeds.

Although it is possible to obtain an oleoreplastic composition that can be employed as an oleoresin thermoplastic resin constituting a lubricating oil, i.e., a natural vegetable oil, a natural mineral oil, a synthetic oil, or a mixture thereof, in any method, It is desirable to set the volume content to 0.3% to 20%. Here, if the content is below 0.3%, the friction reduction effect due to oil impregnation will not appear at all, and on the contrary, 20
If it exceeds %, the strength of the material will decrease, and the hands will slip too much during work, which will be a hindrance to the work.

is formed, and the protrusion 7 is loosely and loosely fitted and connected to the locking female part 8 provided on the tip end 1B. Specifically, the distal end side of the locking protrusion 7 is formed into a disc-shaped head 9 with a slightly larger diameter, and the head 9 is located inside the female locking portion 8 and is inserted into the female portion 8 to prevent it from slipping out. The shape and dimensions are set, and the distal end portion 1B is configured to be swingable in a conical shape with a predetermined apex angle θ relative to the base portion 1A. In the figure, an arrow M indicates a conical oscillating motion made by the distal end 1B, and it is also capable of rotational movement as shown by arrows Q and R in each state of oscillating the head. The guide wheels 6, 6 are at the tip end 1B.
It is rotatably attached to the tip end side as shown by arrows E and F.

擦低減効果を発揮する。 While the tip end 1B of the connecting fitting 1 performs a conical oscillation and rotational movement as shown by arrows M and QR with respect to the base 1A of the connecting fitting 1, the main wire main body 2 moves toward the bent portion 10a of the pipe 10 or Obstructive parts such as stepped parts and joint parts are easily pushed in as shown by arrow G and inserted into the pipe 10. cable 10
When the other end is reached, the material to be wired is connected to the hooking hole 5, and the material to be wired is inserted into the pipe 10 and wired by pulling the main body 2 of the call line in the opposite direction as indicated by the arrow N. I can do it. Therefore, the main wire main body 2 is made of a long linear body made of oil-containing thermoplastic resin.
The surface of the main body 2 slides on the above-mentioned obstacles and bends 10a in the pipe 10, but the surface of the main body 2 of the call line is coated with a thin film of lubricating oil seeped from inside the resin, and the lubricating oil flows through this thin film. The friction coefficient is significantly reduced because the contact surface slides against the obstacle and the like. The inner circumferential bent portion 10b in the pipe 10 makes particularly strong sliding contact when the main wire main body 2 is pulled in the opposite direction, but the oil-impregnated thermoplastic resin in the portion in contact with the portion 10b is bent, and as a result, that portion Since it is compressed, the exudation of the oil droplets contained therein is accelerated and the friction reducing effect is exerted.

擦低減効果が極めて大である。 If the length of the pipe 10 is longer than a certain level, or if it is pulled out with a fairly strong force, the resin surface temperature will instantaneously rise to a considerable extent due to sliding friction, and as a result, oil droplets in the micropores will seep onto the surface. However, since this response occurs instantaneously without any time delay, the effect of reducing friction is extremely large.

In this way, in the present invention, at least the surface layer of the main wire body 2 is made of oil-impregnated thermoplastic resin, so that the inner circumferential surface of the pipe 10 into which the wired material is inserted and wired, and the stepped inside of the pipe 10 are formed. The sliding friction between the reference wire main body 2 and obstacles such as parts and joints can be significantly reduced, and the reference wire main body 2 can be easily pushed, inserted, and pulled out with extremely small force, making the work easier than before. It is possible to shorten the time or reduce the number of workers. Furthermore, since the sliding friction is reduced, it is less likely to wear out, which has the effect of prolonging its life. In particular, when connecting wired materials and pulling them out, when they come into sliding contact with the bent portion 10b of the pipe 10, the sliding portion of the main wire body 2 is deformed and compressed with a certain curvature, so that The amount of oil droplets leached from increases. In addition, when pulling out with a strong force, the temperature of the main wire main body 2 increases due to friction, particularly at the part of the pipe 10 that comes into sliding contact with the bent part 10b and the obstruction part, and the oil droplets in the micropores expand, etc., and similarly reach the surface. Leach. Therefore, the oil film on the parts exposed to severe conditions does not disappear and is instantly replenished.
