Description

TECHNICAL FIELD

[0001] The utility model relates to cable protection pipe technical field, concretely relates to a cable protection pipe with internal support structure. BACKGROUND

[0002] Cable is directly exposed outside without any protection in the past laying process, so that the cable is damaged after being exposed to the sun and rain for a long time, and the service life of the cable is reduced. Therefore, the cable needs to be protected by the cable protection pipe before laying to prolong the service life of the cable. The cable protection pipe refers to the metal protection pipe with certain mechanical strength laid on the outer layer of the cable to prevent the cable from being damaged.

[0003] However, the traditional cable protection pipe is a one-time injection molding pipe, and the structure is simple. When the pressure in the use process is too large, the cable protection pipe is at risk of breaking, affecting the normal use of the cable. UTILITY MODEL CONTENT

[0010] Preferably, the connecting piece is not less than three, and the three connecting pieces are evenly distributed between the inner ring and the outer ring.

[0011] Preferably, the outer protection pipe is provided with a corrosion-resistant coating on the surface.

[0012] The utility model has the advantages of:

[0013] 1. Through the combination of the inner protective tube and the outer protective tube, the cable is double-protected;

[0014] 2. By setting the support structure as an integral columnar structure, the structure is more stable, when being extruded, the external pressure is borne by the support structure, damage to the cable is avoided, and the service life of the cable is effectively improved.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] As shown in the drawings: Figs. 1-3

[0020] In this embodiment, a cable protective tube with an internal support structure comprises a structure main body, the structure main body comprises a cable 5, the cable 5 is externally sleeved with an inner protective tube 4, the inner protective tube 4 is externally sleeved with a support structure 7, the support structure 7 is externally sleeved with an outer protective tube 1, through the combination of the inner protective tube 4 and the outer protective tube 1, the cable 5 is double-protected; the support structure 7 comprises an inner ring 3 and an outer ring 2, a connecting piece 6 is arranged between the inner ring 3 and the outer ring 2, the inner ring 3 is a hollow cylindrical structure, the outer ring 2 is a hollow polygonal structure, through the arrangement of the support structure 7, the external pressure is supported, and the cable protective tube is prevented from being processed for a long time.

[0021] It should be noted that the cable 5, the inner protective tube 4, the support structure 7 and the outer protective tube 1 are arranged in concentric circles, through the double arrangement of the inner protective tube 4 and the outer protective tube 1, the cable 5 is double-protected, through the arrangement of the support structure 7, the external pressure is supported, and the compression resistance of the protective tube is improved. ​

[0022] It should be noted that the support structure 7 is integrally formed, the connecting piece 6 is an arc-shaped sheet structure, the connecting piece 6 is connected with the inner ring 3 and the outer ring 2 on both sides respectively, the connecting piece 6 is not less than three, and the connecting piece 6 is evenly distributed between the inner ring 3 and the outer ring 2. By setting the support structure 7 as an integrally formed structure, the structural stability of the support structure 7 is improved, and the compression resistance of the cable protection pipe is further improved.
