[0010] Preferably, a linkage unlocking frame is provided between the first side plate, the second side plate and the cylinder. The linkage unlocking frame has a central shaft hole inside.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the compressible circulating cable reel includes a first side plate 1 and a second side plate 2, with a cylinder 21 disposed between the first side plate 1 and the second side plate 2; The cylinder 21 is composed of a first part 22 and a second part 23. An incomplete gear structure meshes between the first part 22 and the second part 23, allowing the first part 22 and the second part 23 to rotate relative to each other and undergo axial compression. Locking devices are respectively provided between the first side plate 1 and the cylinder 21 and between the second side plate 2 and the cylinder 21. Multiple locking devices are provided along the circumference of the first side plate 1, and the multiple locking devices are arranged in a circular array. The locking devices are used to lock the relative positions of the first side plate 1, the second side plate 2 and the cylinder 21 when the shaft disk is in the working state. The locking device includes a rotating shaft structure and a cam structure 24 on the cylinder 21. The cam structure 24 has a first slot 32 and a second slot 33. When the rotating shaft structure is engaged in the first slot 32, the shaft disk is in a working locked state. When the rotating shaft structure is engaged in the second slot 33, the shaft disk is in a compression locked state.

[0022] In this embodiment, the cylinder 21 is divided into a first part 22 and a second part 23 connected by an incomplete gear structure, allowing the two parts to rotate relative to each other to achieve axial compression. At the same time, the cylinder 21 and the first side plate 1 and the second side plate 2 are locked together by the first slot 32 and the second slot 33 on the cam structure 24 in the locking device. The shaft disc can be automatically locked after switching between the working state and the compression state. Thus, the shaft disc can be compressed to a smaller volume when unloaded, effectively reducing the storage and transportation space occupied by the unloaded shaft disc. Combined with the locking device, the problem of accidental extension or contraction is avoided, so that the shaft disc remains stable and reliable during handling, storage and use.

[0023] As one implementation method, such as Figure 6 , Figure 7 As shown, the rotating shaft structure includes a base plate 8, the base plate 8 has a bottom panel 11, side panels 12 are fixedly installed on both sides of the bottom panel 11, and a connecting rotating shaft 13 corresponding to the cam structure 24 is fixedly installed on one side of the side panel 12. A connecting hole 16 is provided on the bottom panel 11, and a pivot hole and a first limiting groove 19 and a second limiting groove 20 are provided on the side panel 12. There is a height difference between the first limiting groove 19 and the second limiting groove 20. The second limiting shaft 15 and the first limiting shaft 14 respectively pass through the interior of the first limiting slot 19 and the second limiting slot 20. A limiting buckle 10 is fixedly installed between the second limiting shaft 15 and the first limiting shaft 14. A retaining spring 9 is provided between one end of the second limiting shaft 15 and the first limiting shaft 14 and the limiting buckle 10. A protrusion 17 is provided on the bottom panel 11. A spring 18 is connected between the first limiting shaft 14 and the protrusion 17. The spring 18 is used to pull the first limiting shaft 14 so that it is engaged in the slot of the cam structure 24.

[0024] In this embodiment, when unlocking is required, the second limiting shaft 15 is pressed down, which in turn drives the first limiting shaft 14 to move away from the first slot 32 through the limiting buckle 10. At the same time, the first limiting slot 19 and the second limiting slot 20 restrict the movement of the second limiting shaft 15 and the first limiting shaft 14, allowing them to move along a preset trajectory. After both the second limiting shaft 15 and the first limiting shaft 14 have moved into position, their positions are fixed, and the rotating shaft mechanism is unlocked. The cylinder 21 and the first side plate 1 or the second side plate 2 can move relative to each other through the rotating shaft, thereby achieving axial compression of the entire shaft disc. Then, the fixing of the second limiting shaft 15 and the first limiting shaft 14 is released. Under the tension of the spring 18, the first limiting shaft 14 is engaged in the second slot 33 of the cam structure 24 on the cylinder 21, thereby locking the compressed state. When the compressed cylinder needs to return to its working state after transportation, the first side plate 1 and the second side plate 2 can be directly pulled open due to the cam structure 24 on the cylinder 21. The first limiting shaft 14 will follow the cam trajectory of the cam structure 24 on the cylinder 21 and, under the tension of the spring 18, will be inserted from the second slot 33 into the first slot 32, locking the cylinder 21 and the first side plate 1 or the second side plate 2. No additional tools or complicated unlocking steps are required; simply pulling open the side plate will automatically complete the reset and locking.

[0025] As one implementation method, such as Figure 3 , Figure 4 and Figure 5 As shown, the cam structure 24 is respectively set at one end of the first part 22 and the second part 23, and the support rod 27 is fixedly installed at the connection between the first part 22 and the second part 23. The incomplete gear structure includes an incomplete gear 28 fixedly installed at one end of a first part 22, and an incomplete gear 29 fixedly installed at one end of a second part 23. The incomplete gear 28 and the incomplete gear 29 mesh with each other, and both the incomplete gear 28 and the incomplete gear 29 are movably installed in the support rod 27.

[0026] In this embodiment, the first part 22 and the second part 23 are centrally symmetrical and have corresponding mounting grooves. The mounting grooves accommodate the support rod 27. The first part 22 and the second part 23 are meshed through an incomplete gear 1 28 and an incomplete gear 29 to make the relative rotation angle between the two parts. This ensures that the two parts of the cylinder 21 move in a coordinated manner during folding and unfolding, avoiding the skewing and jamming problems that may occur in traditional hinged structures. As one implementation method, such as Figure 4 As shown, the adjacent ends of the first part 22 and the second part 23 are both set as a combination structure of arc 30 and right angle 31. The two sides of the support rod 27 are respectively provided with gear shaft 25 and gear limit buckle 26 to limit the incomplete gear one 28 and incomplete gear two 29.

[0027] In this embodiment, by using a semicircular arc 30 and a semiright angle 31, rotation is achieved only to one side while the other side is physically limited to avoid errors. This prevents damage to the mechanism or misoperation caused by the operator rotating it in the opposite direction, and improves the safety and reliability of the shaft disc. Meanwhile, the first part 22 and the second part 23 of the cylinder 21 are connected by an incomplete gear 1 28 and an incomplete gear 29. The incomplete gear 1 28 uses a 5-tooth gear and the incomplete gear 29 uses a 4-tooth gear, so that the relative rotation angle between the two parts is exactly 180 degrees.

[0028] As one implementation method, such as Figure 2 , Figure 7 and Figure 9 As shown, a linkage unlocking frame 34 is provided between the first side plate 1, the second side plate 2 and the cylinder 21. The linkage unlocking frame 34 has a central shaft hole 36 inside. Multiple connecting arms 35 are provided in the linkage unlocking frame 34 along the circumference. One end of each of the multiple connecting arms 35 is connected to the first limiting shaft 14, which is used to drive the multiple first limiting shafts 14 to move simultaneously.

[0029] In this embodiment, the first limiting shaft 14 is connected by multiple connecting arms 35. When the number of connecting arms 35 is twelve, the cylinder 21 is more uniform. When compression is required, external pressure can be applied to simultaneously press down all twelve first limiting shafts 14 to improve efficiency and unlock at the same time.

[0030] As one implementation method, such as Figure 1 , Figure 9 As shown, the size of the central shaft hole 36 is the same as the size of the shaft holes of the first side plate 1 and the second side plate 2, and the number of connecting arms 35 is the same as the number of base plate seats 8 and corresponds one-to-one.

[0031] In this embodiment, the central shaft hole 36 is the same size as the shaft hole, which ensures the normal use of the wire feeding frame and the subsequent unlocking device during wire feeding. Twelve connecting arms 35 extend out to connect the first limiting shafts 14 of the twelve cylinders 21, so as to realize their simultaneous pressing and releasing, thereby driving the second limiting shaft 15 to unlock and lock the rotation of the cylinders 21.

[0032] As one implementation method, such as Figure 10 As shown, each connecting arm 35 is provided with a bayonet structure. The bayonet structure includes multiple arm cavities 41 arranged in a ring array inside the central shaft hole 36. Inverted trapezoidal limiting bayonets 38 are slidably installed inside the multiple arm cavities 41. A return spring 37 is sleeved on the outside of the limiting bayonets 38. One end of the return spring 37 is connected to one side of the inverted trapezoidal limiting bayonets 38, and the other end is connected to the inner wall of the arm cavity 41.

[0033] In this embodiment, each of the linkage unlocking frames 34 is provided with an inverted trapezoidal limit slot 38 and a reset spring 37, which can automatically engage and position when the unlocking device is inserted into the linkage unlocking frame 34.

[0034] As one implementation method, such as Figure 2 and Figure 11 As shown, an unlocking device is also provided on one side of the shaft disk. The unlocking device includes an end 43 that is inserted into the central shaft hole 36. A coupling 52 is fixedly installed at one end of the end 43. A secondary end 42 is sleeved on the outside of the coupling 52. A shaft sleeve 51 is sleeved at the end of the coupling 52. Fork posts 44 are fixedly installed on both the left and right sides of bushing 51. A handle 45 is fixedly installed on the other side of fork posts 44. A support frame 48 is fixedly installed on one side of bushing 51. A support shaft 49 is rotatably installed on the support frame 48. A pressure rod 50 is fixedly installed at the top of the support shaft 49. A linkage buckle 47 is movably connected to the outside of the pressure rod 50. The other end of the linkage buckle 47 is connected to the coupling 52.

[0035] In this embodiment, a support beam 46 is fixedly installed at the bottom of the support frame 48 for auxiliary support. Under the limiting and fixing of the bushing 51 and the fork column 44, the fork column 44 is inserted into the forklift hole 3. Due to the inverted trapezoidal shape of the limiting slot 38 and the automatic reset function of the return spring 37, the end 43 is inserted into the interior of the linkage unlocking frame 34, and the linkage unlocking frame 34 is pushed downward together. At this time, pressing down can realize the pressing of the first limiting shaft 14 through the linkage unlocking frame 34, thereby realizing the unlocking between the first side plate 1, the second side plate 2 and the cylinder 21. Pulling the pressure rod 50 backward to nearly 90 degrees, the first limiting shaft 14 is pressed to the bottom, and the shaft plate enters the unlocked state. At this time, locking the position of the pressure rod 50 can perform the compression operation of the shaft plate.

[0036] As one implementation method, such as Figure 11 As shown, end 43 is in the shape of a right frustum, and sub-end 42 is in the shape of an inverted frustum. The diameter of sub-end 42 is larger than the diameter of end 43. End 43 and sub-end 42 are used to cooperate with the limiting slot 38 to realize the engagement and disengagement of the unlocking device and the linkage unlocking frame 34.

[0037] In this embodiment, after compression is completed, the pressure rod 50 is pushed back. At this time, the end 43 separates from the limiting slot 38. Then, the secondary end 42 contacts the limiting slot 38 until the limiting slot 38 pops out again, thereby pressing the secondary end 42 until it contacts the end 43.

[0038] Then pull the pressure rod 50 backward. Due to the inverted frustum shape of the secondary end 42, it can press the limiting slot 38 back downward. At the same time, due to the pressing contact of the limiting slot 38, the secondary end 42 and the end 43 are in contact. Since the diameter of the secondary end 42 is slightly larger than that of the end 43, the secondary end 42 can be withdrawn from the shaft hole of the linkage unlocking frame 34 along with the end 43, so that the compressed shaft disc can complete the subsequent process.

[0039] As one implementation method, such as Figure 1 , Figure 2 and Figure 7 As shown, both the first side plate 1 and the second side plate 2 are flat cylindrical structures. The center of the first side plate 1 and the center of the second side plate 2 are provided with through shaft holes, and multiple support plates 4 arranged in a circular array are connected in the shaft holes. The support plate 4 has forklift holes 3. The outer edges of the first side plate 1 and the second side plate 2 are provided with all-steel corrugated 5. Multiple grooves 6 and multiple through holes 7 are provided on the inner side of the first side plate 1 and the inner side of the second side plate 2 for fixed connection with the base plate seat 8 of the rotating shaft structure.

[0040] In this embodiment, the all-steel corrugated 5 structure achieves weight reduction while ensuring the rigidity and strength of the side plate. The forklift hole 3 facilitates forklift operation and can be combined with the internal fork column 44 of the unlocking device to compress the axle disc. The hollowed-out area around the axle hole facilitates the cable lead-out and makes it easy to observe the internal situation.
