The invention relates to the technical field of cable tubes, in particular to a bending-resistant cable tube, which comprises: an inner tube, wherein four groups of deformation grooves are formed in the circumference of the outer wall of the inner tube at equal intervals, and a plurality of groups of deformation grooves are distributed in the axial direction of the inner tube in an array manner; and four sets of connecting blocks which are circumferentially distributed on the outer wall of the inner tube at equal intervals, wherein the connecting blocks are arranged on the center lines of the two sets of deformation grooves adjacent to the circumference, and the connecting blocks are elastic blocks. Through the four sets of deformation grooves formed at equal intervals, when the inner pipe is transversely and longitudinally bent, the inner pipe extrudes the deformation grooves to be bent, the connecting blocks can enhance the connecting strength between the outer pipe and the inner pipe, the space between the connecting blocks provides the deformation space of the outer pipe, the outer pipe and the inner pipe are synchronously bent, and an anti-deformation assembly is arranged to enhance the recovery capacity of the inner pipe and the outer pipe.
Description
technical field [0001] The invention relates to the technical field of cable tubes, in particular to a bending-resistant cable tube. Background technique [0002] Cable protection tube is also known as cable tube, power cable tube, cement cable tube, power pipe, power cable protection tube, etc. The outside of the cable is wrapped with a protective tube to prevent the core wire from being loose. Because the core wire is highly flexible, It is easy to bend, and the side pressure generated by bending may lead to deterioration of transmission performance, so it is necessary to prevent excessive bending, and at the same time, due to the needs of installation, it is required to be able to bend within a reasonable range. [0003] In the prior art, a circumscribed concave-convex structure is usually used on the outer periphery of the protective sleeve to obtain the effect of preventing excessive bending, but the above-mentioned structure is prone to deformation and failure after re...
