[0021] Various exemplary embodiments of the utility model will now be described in detail with reference to the drawings. It should be noted that: unless otherwise specifically stated, the relative arrangement, numerical expression and numerical value of the components and steps set forth in these embodiments do not limit the scope of the utility model.

[0022] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way limiting of the scope of the utility model and its applications or uses.

[0023] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered as part of the specification for the purposes of the present disclosure.

[0024] In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary, not as a limitation. Therefore, other examples of exemplary embodiments can have different values.

[0025] As Figures 1-2The foldable corrugated pipe for protecting a wire or multiple wires comprises two oppositely arranged semicircular first half pipe bodies 10 and 20 with corrugated surfaces, one of the first half pipe bodies 10 and 20 is connected with at least one connecting part 30, and the other opposite side forms a slit, the connecting part 30 is arranged along the extension direction of the corrugated pipe, and the cross section of the connecting part 30 has at least one bending part 310.

[0026] The existing corrugated pipe has the problems of difficult installation and wasted production time, and the corrugated pipe in the structure is provided with a slit, and the first half pipe body 10 and the first half pipe body 20 are connected through the connecting part 30, so that the corrugated pipe can be folded and opened to wrap the wire. Through this structure, the corrugated pipe can be easily installed on the wire, not only reducing the difficulty of installation, but also greatly shortening the operation time and improving the work efficiency.

[0027] Specifically, the first half pipe body 10 and the first half pipe body 20 respectively include a plurality of wave crests 110 and a plurality of wave troughs 120 arranged in sequence and continuously, and the connecting part 30 is connected with the wave trough 120 of the first half pipe body 10 and the first half pipe body 20 respectively.

[0028] Further, one side of the sealing part 40 adjacent to the connecting part 30 is provided with a sealing part 40 sealing the end of the wave crest 110, and the other side of the sealing part 40 is connected with the connecting part 30, so as to strengthen the stability of the connection between the connecting part 30 and the first half pipe body 10 and the first half pipe body 20.

[0029] As shown in the figure, the protruding direction of the bending part 310 is towards the outer circumferential side of the corrugated pipe. Figure 2

[0030] In an embodiment, in order to avoid the wear of the bending part 310 and weaken the protection of the wire, the inventors set the height of the highest part of the bending part 310 not to exceed the height of the wave crest 110.

[0031] Optionally, the connecting part 30 is a plurality of connecting parts, and the different connecting parts 30 are arranged at intervals along the extension direction of the corrugated pipe, and the connecting parts 30 arranged at intervals are hollow structures.

[0032] The connecting parts 30 are arranged at intervals, and the hollow structures between the different connecting parts 30 avoid the bending difficulty problem caused by the increase of the connecting parts 30. Not only is the installation of the wire bending area convenient, but also the corrugated pipe bending transportation is more convenient, does not occupy space, and the hollow structure also reduces the weight and cost of the corrugated pipe.

[0033] ​Preferably, in order to ensure the firmness and stability of the connection, the distance between adjacent connection portions 30 is not more than the axial length of one wave crest 110 and one wave trough 120.

[0034] In an embodiment, after the first half pipe body 10 and the first half pipe body 20 are buckled and surround the wire, the outer periphery of the first half pipe body 10 and the first half pipe body 20 is wrapped with adhesive tape to fix the wire and the corrugated pipe.
