The invention discloses an optical fiber cable transmission device for information engineering, which comprises a straight transmission pipe, a bent pipe, a secondary transmission pipe, an installation adjustment mechanism, a sliding push structure and a positioning and clamping structure. In the present invention, by providing an installation adjustment mechanism, the first connection structure and the second connection structure can slide up and down on the positioning guide rod through the slider, so that the height position of the straight conveying pipe can be adjusted, and the first connection structure and the second The connection structure can be used to adjust the left and right positions of the straight conveying pipe, so that the optical fiber cable can be better adjusted to improve construction efficiency, and a sliding push structure is set, and the first push wheel and the second push wheel are rolled and matched to each other, which can be passed through Auxiliary pushing of the fiber optic cable through the straight pipe is carried out, so that the fiber optic cable can be better conveyed and the construction efficiency can be improved.
