The wiring harness body 2 can be protected by setting the corrugated tube sheath 1, and dust can be prevented from entering the interior of the corrugated tube sheath 1 and causing blockage inside the corrugated tube sheath 1 by setting two filter screens 4. The corrugated tube sheath 1 can be limited by setting four limiting mechanisms 7, which is convenient for installing the entire sheath and also convenient for disassembling the entire sheath.

[0029] In this embodiment, two insertion holes connected to the inner cavity of the fixing ring 3 are provided on the circumferential outer wall, and the moving rod 77 is slidably plugged into the same side insertion holes on the outer wall of the same side fixing ring 3, so that the moving rod 77 can be smoothly plugged into the same side fixing ring 3.

[0030] In addition, a guide groove is provided on the right side surface of the vertical plate end of the vertical plate 71, and a guide block 79 is fixed on the outer wall of the connecting block 78, which is slidably connected to the guide groove on the left side surface of the vertical plate end of the vertical plate 71 on the same side, so as to guide the movement of the connecting block 78, thereby guiding the movement of the moving rod 77 and the clamping rod 76.

[0031] Furthermore, a surface of the clamp rod 76 away from the same-side moving rod 77 is tightly fitted with the outer wall of the wiring harness body 2, and a double-sided tape is provided on a surface of the clamp rod 76 away from the same-side moving rod 77, which can make the limiting effect of the clamp rod 76 better.

[0032] Specifically, the filter screen 4 corresponds to the position of the wiring harness body 2 and is matched in size. A sealing ring 5 matched in size is fixed on the inner wall of the filter screen 4, and the outer wall of the wiring harness body 2 is tightly fitted with the inner wall of the sealing ring 5, which can make the sealing between the wiring harness body 2 and the filter screen 4 better.

[0033] It is worth noting that the limiting mechanism 7 also includes a pull rod 75 fixed on the outer wall of the movable plate 74, and the length of the pull rod 75 is 1-3 cm, preferably 2.5 cm in this article, so as to facilitate the movement of the movable plate 74, and then facilitate the movement of the movable rod 77 and the clamping rod 76.

[0034] It is worth noting that two symmetrical handles 6 are fixed on the surface of the side of the fixing ring 3 away from the corrugated tube sheath 1, and the shape of the handles 6 is U-shaped, so as to facilitate the movement of the entire sheath.

[0035] It is worth emphasizing that the transverse cross-sectional shape of the guide groove on the right side surface of the vertical plate end of the vertical plate 71 is I-shaped, and the shape of the guide block 79 is I-shaped to match the shape of the guide groove on the right side surface of the vertical plate end of the vertical plate 71, which can make the connection between the guide block 79 and the guide groove on the right side surface of the vertical plate end of the vertical plate 71 on the same side tighter, and indirectly make the moving rod 77 and the clamping rod 76 more stable during the dizziness process.

[0036] Among them, the corrugated tube sheath 1 and the wire harness body 2 involved in this embodiment are prior arts, and their structures and working principles are well known to those skilled in the art, and are not described in detail here.

[0037] When the whole sheath needs to be disassembled during the specific use of this embodiment, the staff slowly pulls the four movable plates 74 through the four pull rods 75 respectively. The movement of the movable plates 74 compresses the springs 72 fixed thereto on the same side. The movable plates 74 move under the guidance of the connecting blocks 78, the guide blocks 79 and the guide grooves on the right side surface of the vertical plate end of the vertical plate 71 on the same side. The movement of the movable plates 74 drives the movable rods 77 fixed thereto to move. The movement of the movable rods 77 drives the clamping rods 76 on the same side fixed thereto to move away from the wiring harness body 2 until the double-sided adhesive on the outer wall of the clamping rod 76 separates from the wiring harness body 2 and moves to a suitable position. Then, the pulling of the four pull rods 75 is stopped. Then, the wiring harness body 2 can be separated from the corrugated tube sheath 1. After separation, the four pull rods 75 are slowly loosened, so that the four springs 72 can be restored to their original length. According to the above, the whole sheath can be installed otherwise.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
