The outer wall of the inner pipe body is provided with a convex strip matched with the C-shaped groove;

and the convex strips are provided with buffer cavities.

Wherein, the quantity of reinforcing plate is 3.

Wherein the annular array of reinforcing plates is distributed outside the core tube.

And a support plate corresponding to the vertical plate is axially arranged on the inner wall of the outer pipe body.

Wherein, backup pad, riser and bottom plate all adopt aluminum alloy plate to process to form, and backup pad, riser and bottom plate integration machine-shaping.

Contrast prior art not enough, the utility model provides a beneficial effect that technical scheme brought: when using, when the cable received outside impact, the outer body transmitted the reinforcing plate with the impact, transmitted the sand grip by the reinforcing plate again, reduced external force through the cushion chamber in the sand grip, and then avoided the cable to suffer the striking of external force, increased the support intensity between outer body and the interior body through the enhancement layer simultaneously, further protected the cable not receive the influence of outside impact, improved cable protection effect.

The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The present invention is further described with reference to fig. 1-2.

A cable extrusion-proof protection pipe comprises a reinforcing plate 10, an outer pipe body 20 and an inner pipe body 30, wherein the inner pipe body 30 is concentrically arranged inside the outer pipe body 20, the reinforcing plate 10 is circumferentially arranged in a gap between the outer pipe body 20 and the inner pipe body 30 respectively, and the reinforcing plate 10 reinforces the structural strength of the outer pipe body 20 and the inner pipe body 30.

The reinforced plate is characterized in that a reinforced layer 4 positioned between adjacent reinforced plates 10 is arranged between the outer pipe body 30 and the inner pipe body 20, and the reinforced layer is formed by mixing and processing glass fibers and ABS fibers and has the characteristics of light weight, high strength and corrosion resistance.

The reinforcing plate 10 comprises a vertical plate 11 and a bottom plate 12 respectively, one end of the vertical plate 11 is connected with the outer pipe body 20, the other end of the vertical plate is connected with the bottom plate 12, a C-shaped groove 121 for clamping the inner pipe body is formed in the bottom plate 12, when the outer pipe body 20 is subjected to external radial impact force, on one hand, the counterforce on the impact force is increased through the reinforcing layer 4, the impact force is reduced, on the other hand, the reinforcing plate 10 is used for reinforcing support, the force entering the cable is reduced jointly, and therefore the probability that the cable is damaged is reduced.
