[0017] In order to make the technical personnel of the technical field better understand the present utility model scheme, the technical scheme in the present utility model embodiment will be clearly and completely described below in conjunction with the drawings in the present utility model embodiment. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by the technical personnel in the technical field belonging to the present utility model. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0018] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] like Figure 1-Figure 5 As shown, a combined porous communication tube includes a plurality of cable tubes 1 and protective sleeves 2 connected together. The surfaces of the cable tubes 1 are provided with connecting strips 11 and connecting grooves 12 respectively. The connecting strips 11 and connecting grooves 12 of two adjacent cable tubes 1 can be plugged into each other. In this embodiment, the cable tubes 1 are connected together by 4 combinations, and the connecting strips 11 and connecting grooves 12 on each cable tube 1 are arranged in a perpendicular direction. A plurality of pressing plate assemblies 4 for pressing the cable tubes 1 are provided on the inner walls at both ends of the protective sleeve 2. The number of pressing plate assemblies 4 is equal to the number of cable tubes 1 and corresponds one to one. The pressing plate assemblies 4 include pressing plates 41 and elastic members. Each pressing plate 41 is detachably connected to the protective sleeve 2 through an elastic member, and the pressing plate 41 is pressed against the surface of the cable tube 1 by means of the elastic member.

[0020] The elastic member includes a spring 42 and a connecting block 43. One end of the spring 42 is connected to the pressing plate 41, and the other end of the spring 42 is connected to the connecting block 43. The inner wall of the protective sleeve 2 is provided with a first slot 22 that cooperates with the connecting block 43. During installation, after the combined cable tube 1 is inserted into the protective sleeve 2, the connecting block 43 is inserted into the first slot 22 of the protective sleeve 2. Under the elastic force of the spring 42, the pressing plate 41 is pressed on the outer surface of the cable tube 1, thereby fixing the combined cable tube 1. In order to facilitate positioning, a limiting groove 13 that is engaged with the pressing plate 41 is provided on the outer tube wall of the cable tube 1. Under the elastic force of the spring 42, the pressing plate 41 is clamped in the limiting groove 13.

[0021] In order to further protect the cable, a compression buffer strip 3 is provided on the inner wall of the protective sleeve 2 between two adjacent cable tubes 1. One end of the compression buffer strip 3 is detachably connected to the protective sleeve 2, and the other end of the compression buffer strip 3 abuts against the cable tube 1. The compression buffer strip 3 can be made of rubber material. When the outer tube is subjected to force, the compression buffer strip 3 deforms and buffers, thereby reducing the force on the cable tube 1 and protecting the cable tube 1.

[0022] In order to facilitate disassembly and assembly, the compression buffer strip 3 is provided with a second slot 31, and the inner wall of the protective sleeve 2 is provided with an insert strip 21 that cooperates with the second slot 31, and the outer end of the insert strip 21 has a head that is larger than the width of the insert strip 21. This structure facilitates the insertion and connection of the compression buffer strip 3.

[0023] During installation, the connecting strips 11 and connecting grooves 12 of adjacent cable tubes 1 are plugged together, so that four cable tubes 1 are combined and connected together, and then the compression buffer strip 3 is plugged and connected with the plug strip 21 of the protective sleeve 2, and the combined cable tube 1 is inserted into the protective sleeve 2, and the connecting block 43 is inserted into the first slots 22 at both ends of the protective sleeve 2, and then under the action of the spring 42, the pressing plate 41 is inserted into the limit groove 13 on the surface of the cable tube 1, so that the combined cable tube 1 is fixed, and the protective sleeve 2 plays a good protective role on the cable tube 1. When in use, different cables are inserted into different cable tubes 1, the cable separation effect is good, and heat is not easy to accumulate. During use, when the protective sleeve 2 is subjected to external force, the compression buffer strip 3 is deformed and buffered, absorbing the buffering energy, reducing the damage to the cable tube 1 and extending the service life of the pipe. Even when the cable tube 1 or the protective sleeve 2 is partially damaged, a single cable tube 1 is changed or the protective sleeve 2 is replaced separately, which is convenient for maintenance and reduces maintenance costs.

[0024] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
