[0026] The following will be combined with 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.

[0027] like Figure 1~Figure 5 As shown, a moisture-proof shield machine cable and its winding mechanism, the structure of which includes a protective shell 2. Among them, the placement inner layer 21 in this embodiment is arranged in the protective shell 2, and the cross-sections of the protective shell 2 and the placement inner layer 21 are both annular structures. A plurality of first partition plates 211 are fixedly arranged on the inner wall of the placement inner layer 21. The first partition plates 211 in this embodiment are made of elastic material, which ensures the strength of the cable itself and is not easy to be crushed, and ensures that the cable can be bent and stored. The first partition plate 211 divides the placement inner layer 21 into a plurality of placement cavities 213, ensuring that the wires 212 are separated and not easily affected by electromagnetic interference. The wires 212 are arranged in each placement cavity 213, a cavity is arranged between the protective shell 2 and the placement inner layer 21, and a plurality of second partition plates 22 are arranged in the cavity, and each second partition plate 22 divides the water absorption layer into a plurality of water absorption cavities 23, and the water absorption cavity 23 is filled with activated carbon 24. The storage mechanism is arranged on the protective shell 2, and is used to store or release the cable. The protective shell 2 used in this embodiment is made of rubber material, so that water vapor itself is not easy to enter. However, since the shield machine is in a humid and dark environment for a long time, water vapor may still easily enter the cable. Therefore, a water absorption chamber 23 and activated carbon are set to ensure that a small amount of water vapor entering the cable is further absorbed by the activated carbon 24, so that the cable is always kept in a dry state.

[0028] The storage mechanism in this embodiment includes a storage shell 1, and a rotating member 4 is arranged in the storage shell 1. The adjustment structure is arranged between the rotating member 4 and the storage shell 1, and is used to shrink the length of the cable or extend the length of the cable by winding. The locking structure is arranged on the adjustment structure, and is used to keep the cable length adjustment structure unchanged. The control structure is arranged on the locking structure, and is used to control the locking structure to move closer to or away from the adjustment structure. The visual window 18 is arranged on the outer wall of the storage shell 1.

[0029] The mounting notch 17 in this embodiment is arranged on the outer wall of the storage housing 1, and the viewing window 18 is fixed to the mounting notch 17 by screw thread, and the viewing window 18 is made of glass material. This is convenient for viewing the specific situation of the storage cables in the storage housing 1, and convenient for releasing and storing the cables.

[0030] The rotating hole 14 in this embodiment is arranged at the top of the storage housing 1, and is rotatably connected to the rotating member 4. The rotating handle 5 is fixedly arranged on the rotating member 4, and the rotating handle 5 is perpendicular to the central axis of the rotating member 4, and the cross section of the rotating handle 5 is a "cross" structure. With such a design, when the rotating handle 5 is rotated 90 degrees, its shape will not change, so that the operator can hold and operate the rotating handle 5 more easily.

[0031] The storage housing 1 in this embodiment is a cylindrical structure, the storage cavity 15 is arranged in the storage housing 1, the adjustment structure includes a threading hole 42, the rotating member 4 is a cylindrical structure, and the central axis of the rotating member 4 coincides with the central axis of the storage housing 1. The rotating hole 14 is arranged at the top of the storage housing 1, and it is rotatably connected with the rotating member 4. The inlet 11 and the outlet 12 are arranged on the storage housing 1. The threading hole 42 is arranged on the rotating member 4, and the threading hole 42, the inlet 11 and the outlet 12 are all located on the same diameter line of the rotating member 4. Such a design ensures that the cable can directly pass through the threading hole 42, the inlet 11 and the outlet 12 at one time during installation, simplifying the installation process. Since the threading hole 42, the inlet hole and the outlet hole are arranged in this embodiment, the storage housing 1 can be moved to any position on the cable for storage, replacing the traditional design that can only store the cable end, which is more flexible and has richer application scenarios. In this embodiment, the cable release length can be adjusted by rotating the rotating member 4, and the operation is relatively convenient.

[0032] The locking structure in this embodiment includes a locking member 8, a sliding groove 16 fixedly arranged on the inner wall of the storage chamber 15, the locking member 8 and the sliding groove 16 are slidingly connected, the external thread 41 is arranged on the outer wall of the rotating member 4, the locking groove 83 is arranged on the side of the locking member 8 close to the rotating member 4, and the internal thread 831 is arranged on the locking groove 83, which is threadedly matched with the external thread 41. A limiting structure for limiting the sliding of the rotating member 4 relative to the locking member 8 is also provided between the rotating member 4 and the locking member 8. When the locking member 8 is close to the rotating member 4, the external thread 41 cooperates with the internal thread 831, and the limiting member limits the sliding of the rotating member 4, so that the rotating member 4 is locked by the locking member 8 and cannot rotate.

[0033] The limiting structure in this embodiment includes a limiting plate 6, the bottom cover 3 is connected to the bottom of the storage shell 1 by threads, the limiting plate 6 is arranged at the upper end of the bottom cover 3, the limiting cavity is arranged between the bottom cover 3 and the limiting plate 6, and the second sliding hole 61 is arranged on the limiting plate 6, which is slidingly connected with the rotating member 4. The second limiting bolt 7 is rotatably arranged in the limiting cavity, and is fixedly connected with the rotating member 4. Such a design ensures that the rotating member 4 can only rotate relative to the storage shell 1, and cannot move relative to the storage shell 1, and the thread locking of the locking structure can realize the locking function of the storage shell 1.

[0034] The control structure in this embodiment includes an adjusting bolt 9, an adjusting hole 13 is arranged on the receiving shell, the adjusting hole 13 is threadedly connected with the adjusting bolt 9, and a limiting groove 81 is arranged on the locking member 8. A first sliding hole 82 is arranged on the groove wall of the limiting groove 81, and it is slidingly connected with the adjusting bolt 9. A first limiting bolt 91 is arranged in the limiting groove 81, and the first limiting bolt 91 is fixedly connected with the adjusting bolt 9. Such a design enables this embodiment to realize the locking function by moving the locking member 8 away from or close to the rotating member 4 by simply rotating the adjusting bolt 9. It is ensured that the adjusted control structure can be maintained.

[0035] The working process of this embodiment is as follows: when the cable needs to be stored, first rotate the adjusting bolt 9 in the opposite direction to drive the locking member 8 to disengage from the rotating member 4, then rotate the rotating handle 5 in the opposite direction to release all the stored cables, and then move the storage housing 1 to the center of the position where the cable needs to be stored, and then rotate the rotating handle 5 forwardly. The cable is wound around the rotating member 4 as the rotating member 4 rotates. At this time, rotate the adjusting bolt 9 forwardly to drive the locking member 8 close to the rotating member 4, and rely on the threaded connection between the two to relatively lock the positions of the two; when the cable length needs to be released, just rotate the adjusting bolt 9 in the opposite direction to drive the locking member 8 to disengage from the rotating member 4, and then rotate the rotating handle 5 in the opposite direction to release the cable to an appropriate length, and then rotate the adjusting bolt 9 forwardly to fix the released length of the cable.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
