Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in more detail as follows.

1 is an exploded perspective view illustrating the present invention, FIG. 2 is a longitudinal sectional view of the main part according to FIG. 1, and FIG. 3 is a front sectional view of the main part according to FIG. 2.

As shown in the chain chain for the cable chain used to protect and move the cable or oil pressure hose introduced in accordance with the movement to be refracted at various angles in the industrial robot or a device and a device having a plurality of joints,

The present invention forms a half arc-shaped fitting portion 12 and a locking jaw 14 at the rear end of the center with a synthetic resin material, and the other end of the half arc-type inserting portion detachable by the interference fitting method corresponding to the fitting portion. A shaft portion (10) formed with (16);

A plurality of partition plates (20) formed on an outer surface perpendicular to the longitudinal direction of the shaft portion;

The chain is formed between the partition plate and the partition plate formed with a space portion 32 through which the cable is introduced and the guard band 30 having a width smaller than the length of the shaft portion is integrally formed so that the ends of the partition plate are interconnected. It is shown that a plurality of spheres (1) are coupled.

In other words, a half arc-shaped fitting portion formed at the tip of the shaft portion is formed into a cable chain (C) form by combining a plurality of lengths required by an interference fitting method with the insertion portion formed corresponding to the fitting portion at the ends of other chain spheres. Will be.

In the above, it is preferable that the width of the guard band has a ratio of about 1: 3 to the length of the shaft part so as to have a smooth flow radius upon refraction at various angles, that is, to minimize interference between the guard bands according to the flow radius. Do.

In addition, a plurality of locking ribs 42 are formed on the outer surface of the fitting portion 12, and each of the locking grooves 44 has a predetermined width at a position corresponding to the locking ribs of the coupling portion 16. By having a rotation limiting portion 40 having a, it is to limit the rotation range of the chain sphere in the fastened state to be connected to each other continuously as described above. That is, the locking rib formed by the fitting portion of the one chain chain is caught in the locking groove having a predetermined width formed by the coupling portion of the other chain sphere, so that the chain sphere is not rotated completely but is rotated only in the range defined by the locking rib and the locking groove. It is possible to prevent the cable or the hydraulic pressure hose introduced into the space portion due to the rotation of the sphere.

In addition, since the guard strip 30 between the partition plate 20 and the partition plate 20 has an inlet 50 having a cutting line 52 formed therein, one side of the cable or hydraulic pressure hose is introduced into the space. Since it is possible to insert by pushing through the cutting line of the inlet portion to insert from the cable has a condition that can be easily introduced into the cable and hydraulic pressure hose.

Figure 4 is a main part showing a state of use of the subject innovation.

Afterwards, the cable chain connected to the plurality of chain spheres is flowed as the industrial robot or the apparatus having the joint portion is driven, that is, the half arc-shaped fitting portion formed at the shaft portion of one side chain sphere up, down, left and right. In the insertion portion formed in the shaft portion of the other side of the chain freely move, the restriction of the flow width of the upper, lower, left, right is caught by the locking jaw formed at the rear end of the insertion portion to receive the fluidity proposal.

Accordingly, the upper, lower, left, and right flow widths of the fitting portion and the insertion portion formed in a semi-arc shape can be freely flowed by the width that is caught by the locking step formed at the rear end of the insertion portion.

In addition, the rotation radius of the chain is also limited due to the rotation limiting part rotated by the width of the locking groove formed by the locking ribs formed by the fitting portion and the insertion portion, that is, the locking ribs formed in the one chain and the other chain and By restricting the radius of rotation of each chain by the locking groove, the cable and the hydraulic pressure hose introduced into the space can minimize the twist due to the rotation of the chain.

Therefore, even industrial robots and devices and apparatuses having a plurality of joints can be freely refracted at any angle, and have a condition that they can be stably used without abnormality of cables or hydraulic pressure hoses introduced thereto.

As described above, the present invention is freely deflected at any angle of movement in an industrial robot or a device and a device having a plurality of joints, and thus, it is stably free from twisting, detachment, and stripping of an incoming cable or a pneumatic hose. It will have a protective effect.

In addition, by limiting the rotation radius of the chain sphere, there is also an effect that can minimize the twist of the drawn cable and the hydraulic pressure hose, such as due to the rotation of the chain sphere.

In addition, the cable and the hydraulic hose to be introduced into the space portion of the chain tool can be easily inserted into the outer side of the cable and the hydraulic hose, instead of being pushed in from one side, the cable and the hydraulic hose can be easily introduced.
