Description

Technical Field

[0001] The utility model relates to the technical field of cable protection tubes, in particular to a compression-resistant cable protection tube. Background Art

[0002] Cable protection tube refers to a metal protection tube with a certain mechanical strength that is laid on the outer layer of the cable to prevent the cable from being damaged. Cable protection tubes are mainly installed in areas where communication cables and power lines intersect to prevent power lines from breaking and causing short circuit accidents.

[0003] Currently, the previous generation of cable protection tubes are made of MPP (microporous expanded polypropylene) material, and the structural part is mainly composed of a tube body and a connecting sleeve fixed at one end. This type of cable protection tube is suitable for scenarios with general pressure environments. When subjected to strong impact loads, it is prone to deformation, damage, and breakage. It is not suitable for scenarios with high requirements for specific pressure strength and safety protection.

[0004] In view of this, it is particularly important to design and manufacture a cable protection tube with better impact load resistance and compressive strength during the design, manufacture and use of cable protection tubes. Utility Model Content

[0005] The utility model aims to solve the problem that the impact resistance and compressive strength of the traditional cable protection tube are not enough to meet the use requirements under the specific high pressure bearing strength and safety protection requirements, and proposes a compression-resistant cable protection tube.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A compression-resistant cable protection tube comprises a tube body and a connecting sleeve integrally fixed on one end of the tube body, wherein a compression-resistant part for comprehensively enhancing the compression resistance of the tube body is arranged outside the tube body.

[0008] As a further description of the above technical solution:

[0009] The pressure-resistant part includes a plurality of support rings integrally fused to the outside of the tube body by injection molding and a plurality of reinforcing ribs installed at equal angles between the plurality of support rings.

[0010] As a further description of the above technical solution:

[0011] The pressure-resistant part also includes an outer protective tube sleeved on the outside of the tube body.

[0012] As a further description of the above technical solution:

[0013] The outer diameters of the plurality of support rings are the same as the outer diameter of the tube body, and the inner diameters of the plurality of support rings are greater than the inner diameter of the tube body.

[0014] As a further description of the above technical solution:

[0015] The multiple support rings and reinforcing ribs are all made of alumina ceramic material.

[0016] As a further description of the above technical solution:

[0017] The outer casing is made of polyetherketone material.

[0018] As a further description of the above technical solution:

[0019] The pipe body and the connecting sleeve are both made of microporous foamed polypropylene material.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0021] In the utility model, the previous generation of cable protection tubes are scientifically and rationally improved, and support rings, reinforcing ribs and outer protective tubes are arranged on the outside of the tube body. First, a plurality of support rings made of alumina ceramic material can perform multi-section compression reinforcement treatment on the tube body. Secondly, the reinforcing ribs connected between the plurality of support rings can perform internal support treatment on other parts of the tube body. Finally, the outer protective tube sleeved on the outside of the tube body is made of polyetherketone material. Compared with the tube body structure made of MPP material, it has more excellent pressure bearing capacity, strength and rigidity, and can wrap and strengthen the tube body part. This structure can comprehensively strengthen the cable protection tube in terms of impact load resistance and compressive strength, reduce the occurrence of deformation, damage and fracture of the cable protection tube when it is subjected to impact load, thereby improving the impact resistance and extrusion resistance of the cable protection tube, and meeting the use requirements of the cable protection tube under high pressure strength and high safety protection requirements.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-3 The utility model provides a technical solution: a pressure-resistant cable protection tube, comprising a tube body 1 and a connecting sleeve 101 integrally fixed on one end of the tube body 1, and a pressure-resistant part for comprehensively enhancing the pressure resistance of the tube body 1 is arranged on the outside of the tube body 1.

[0029] Specifically, Figure 1-3 As shown, the pressure-resistant part includes a plurality of support rings 2 which are integrally integrated with the outside of the pipe body 1 by injection molding and a plurality of reinforcing ribs 201 which are installed at equal angles between the plurality of support rings 2. The pressure-resistant part also includes an outer casing 3 which is sleeved on the outside of the pipe body 1, wherein the plurality of support rings 2 can perform multi-section pressure-resistant reinforcement on the middle part of the pipe body 1, the plurality of reinforcing ribs 201 can provide structural support to the inside of the pipe body 1, and the outer casing 3 can wrap and reinforce the outside of the pipe body 1, thereby improving the overall pressure-resistant bearing capacity, strength and rigidity of the pipe body 1.

[0030] Among them, the outer diameter of the multiple support rings 2 is the same as the outer diameter of the tube body 1, and the inner diameter of the multiple support rings 2 is larger than the inner diameter of the tube body 1. This structural setting allows the multiple support rings 2 to withstand external forces at the same time as the tube body 1, and the reinforcing ribs 201 connected between the multiple support rings 2 are hidden in the tube body 1, and the tube body 1 is internally supported, thereby performing multi-directional structural reinforcement operations on the tube body 1, improving the impact resistance and compressive strength of the tube body 1 after manufacturing.

[0031] Specifically, Figure 1-3 As shown, the multiple support rings 2 and the reinforcing ribs 201 are all made of alumina ceramic material. The alumina ceramic material has the characteristics of high hardness, impact resistance, excellent compressive strength, tensile strength and light weight. After being formed on the tube body 1 by injection molding, the structure of the tube body 1 can be strengthened. Since it is made of non-metallic material, it will not barrier or block the cable signal, thereby ensuring the normal use of the cable.

[0032] The pipe body 1 and the connecting sleeve 101 are both made of microporous foamed polypropylene material. The microporous foamed polypropylene has a certain degree of rigidity and toughness. The manufactured pipe body 1 can be used in general pressure-bearing environments.

[0033] The outer casing 3 is made of polyetherketone material, which is a plastic material that performs well under high temperature and high pressure environments. It has excellent pressure bearing capacity, high strength and high rigidity, and its mechanical properties are far superior to those of microporous foamed polypropylene materials. However, its material cost is higher than that of microporous foamed polypropylene materials, so it is formed on the outside of the pipe body 1 in the form of a sheath, which can increase the mechanical properties of the original pipe body 1 and reduce the manufacturing cost of the cable protection pipe processing.

[0034] Working principle: When processing the cable protection tube, the microporous foamed polypropylene is filled between the multiple support rings 2 and the reinforcing ribs 201 by injection molding. After cooling and solidification, the tube body 1 and the connecting sleeve 101 can be formed. The outer diameter of the processed tube body 1 is the same as that of the multiple support rings 2. Such a structural distribution can transfer the impact force and extrusion force to the support ring 2 with better impact resistance and compressive strength when the tube body 1 is subjected to external impact loads. At the same time, the reinforcing ribs 201 connecting the multiple support rings 2 will be hidden in the tube body 1. On the other side, the other parts of the pipe body 1 can be internally supported to improve the overall load-bearing and impact resistance stability of the pipe body 1. Finally, the outer casing 3 supported by the polyetherketone material is fixed between the outside of the pipe body 1 and the connecting sleeve 101, and the pipe body 1 and multiple support rings 2 can be wrapped and protected. At the same time, since the polyetherketone material has mechanical properties that are superior to those of microporous foamed polypropylene material, a barrier with high impact strength and compressive strength can be formed on the outside of the pipe body 1, which comprehensively improves the overall impact resistance and compressive strength of the cable protection tube after processing.
