Description

Cable veyor apparatus

The present invention relates to a cable bare device, and to a cable bare device capable of having a flexible bend while protecting an internal cable or hose.

In general, a cable veyor is widely used throughout industries such as automobiles, industrial machines, and automation equipment to prevent contamination of cables or hoses provided in the internal space, and to prevent damage and corrosion.

Conventional cable bears are used in the form of a tube by bending a ferrous metal plate, or in the form of a chain or corrugated tube in which a plurality of non-ferrous metal units are repeatedly fastened in a line.

The cable bear in the form of a tube in which a double metal plate was bent was difficult to be flexible in a bent area of a square due to deformation according to strength. In order to have flexible flexibility, as an example, a track-type structure in which a pair of unit bodies are repeatedly fastened with supports such as screws up and down or left and right was used. As another example, a structure in the form of a corrugated tube in which the concave and convex parts are engaged while the unit body in which the concave and convex parts are formed is surrounded.

As described above, the conventional cable bear has the flexibility to form bending through the rotation or flow of each unit, but the conventional cable bear has a lot of noise and vibration due to friction of the unit, and is exposed to the outside and between multiple units. There was a problem in that protection and flexibility were lowered due to interference.
