Description

Technical Field

[0001] The utility model relates to a flower-printed flat-wire cable core. Background Art

[0002] In the field of engineering machinery, armored push-pull cable cores are widely used. Armored push-pull cable cores are used to pull the steel wire ropes that change the gear of the transmission, clutch, brake, and pull rods to change the speed or traction of machine tools, cars, tractors, etc., cargo or door locks. They are composed of many different diameters and are usually installed on engine carburetors, fuel pumps, throttles, transmissions, clutches, and wheel hubs. The bonding force between the outer flat steel wire and the inner steel wire rope is a very important technical indicator.

[0003] Chinese patent CN219342682U discloses an armored push-pull cable core, which improves the bonding strength between the flat steel belt and the center rope to a limited extent, but the result is not very satisfactory. Therefore, it is particularly important to seek a cable core with higher bonding strength between the outer flat steel wire and the inner steel wire rope. Utility Model Content

[0007] Preferably, the first steel wire rope, the second steel wire rope and the third steel wire rope have the same diameter.

[0008] As a preference, the number of the protrusions is at least three rows, and the protrusion width a exceeds 1 / 10 of the diameter of the center rope.

[0009] As a preferred embodiment, the diameter of the twisted steel wire is Φ6.7mm±0.20mm, the wire lay pitch is 100±20mm, the wire diameter after being wound around the flat steel strip is Φ7.7±0.20mm, the flat steel strip lay pitch is 7.6±2mm, and the flat steel strip winding coefficient is 7.6.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The outer flat steel belt of the utility model is a special-shaped flat steel belt. The protrusions on the inner wall are evenly interrupted and staggered by the third steel wire rope of the outer layer of the center rope to form a flower print and achieve a state of staggered and tightly combined. Compared with the conventional structure, the bonding strength of the flower print type flat wire rope core of this structure is significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS
