[0002] In the prior art, a cable reel needs to be used to wind the cable, and the long cable is wound into a bundle to facilitate storage of the cable.

[0003] The existing cable reeling device will wear out its bearings after long-term operation, which will increase the resistance to the reel's rotation when reeling in the cable and make it difficult to reel in the cable. Utility Model Content

[0004] The technical problem to be solved by the present invention is that after long-term use, the existing cable reeling device has large resistance when reeling in the cable, making it difficult to reel in the cable. The purpose is to provide a cable reeling device that provides an oil channel to lubricate the bearings installed on the device, thereby reducing the friction inside the bearings and the wear of the bearings, thereby ensuring that the cable can be reeled in smoothly.

[0005] The utility model is achieved through the following technical solutions:

[0006] A cable winding device includes a fixed disk, a reel and a lubrication structure, wherein a turntable is rotatably connected to the fixed disk; the reel is rotatably connected to the fixed disk, and the bottom of the reel is connected to the turntable; the lubrication structure includes an oil storage cylinder, an oil channel and an electric switching valve, and the channel between the oil storage cylinder and the oil channel is opened and closed by the electric switching valve.

[0007] The beneficial effects of the present invention are that, by arranging a fixed disk to support the reel and by arranging a turntable rotatably connected to the reel, when the reel rotates, the turntable rotates synchronously to support the reel, preventing the reel from deflecting during rotation due to an excessively large reel diameter or uneven force on the reel, thereby ensuring that the reel can smoothly reel in the cable; and by arranging a lubrication structure, it is convenient to open the oil channel through the electric switch valve before reeling in the cable to lubricate the bearings installed on the device, reduce the friction inside the bearings, reduce the wear of the bearings, and ensure smooth reeling of the cable.

[0008] In some embodiments, an outer shaft is disposed at the center of the fixed disk, and a first bearing is mounted on the inner side of the rotating disk, with the inner ring of the first bearing being sleeved on the outer shaft. The first bearing ensures smooth rotation of the rotating disk and reduces friction between the rotating disk and the fixed disk.

[0009] In some embodiments, the inner shaft is engaged with the inner shaft hole of the outer shaft, the oil reservoir is disposed at the top of the inner shaft, and the oil passage includes a first oil passage disposed on the outer shaft. The first oil passage connects the oil reservoir to the first bearing, which constitutes the bearing. By locating the oil reservoir at the top of the inner shaft, lubricating oil in the oil reservoir can flow through the first oil passage to the location where the first bearing is mounted, thereby lubricating the first bearing, reducing friction during operation, and minimizing losses in the first bearing.

[0010] In some embodiments, a second bearing and a third bearing are mounted at each end of the outer shaft, the inner rings of the second bearing and the third bearing being sleeved onto the inner shaft. The oil passage further comprises a second oil passage extending along the height of the outer shaft, connecting the oil reservoir to both the second and third bearings through the second oil passage, with the second and third bearings constituting the bearing. The provision of the second oil passage facilitates lubricating oil within the oil reservoir to flow through the second oil passage to the locations where the second and third bearings are mounted, thereby lubricating the second and third bearings, reducing friction during operation, and minimizing losses in the second and third bearings.

[0011] In some embodiments, the bottom of the oil reservoir is provided with a through hole connected to the oil channel, and the electric switch valve is provided in the through hole. By providing the through hole at the bottom of the oil reservoir, the through hole can be opened and closed by the electric switch valve to save the amount of lubricating oil used.

[0012] In some embodiments, a plurality of roller mechanisms are provided between the fixed disk and the rotating disk. The roller mechanisms are evenly distributed at the bottom of the outer ring of the rotating disk and can rotate along the outer ring of the fixed disk. The roller mechanisms are provided to support the rotation of the rotating disk and reduce resistance during the rotation of the rotating disk.

[0013] In some embodiments, the roller mechanism includes a roller and a bracket, wherein the bracket is connected to the bottom of the outer ring of the turntable, and the roller is rotatably connected to the bracket, and the roller can rotate along the outer ring of the fixed plate. By providing a bracket to mount the roller, the roller can rotate along the outer ring of the fixed plate, thereby reducing the resistance during the rotation of the turntable.

[0014] In some embodiments, the bracket is generally N-shaped, with through-holes provided on both side walls of the bracket. An eccentric structure is mounted in each of the through-holes. An axle is mounted on the eccentric structure, and the roller is rotatably connected to the axle. The N-shaped bracket facilitates contact between the roller and the outer ring of the fixed disk through the opening of the N-shape, and the eccentric structure for mounting the roller facilitates adjustment of the roller's height.

[0015] In some embodiments, the eccentric structure includes an eccentric block, which is generally cylindrical and has an eccentric hole. The wheel axle is inserted into the eccentric hole, and the eccentric block is rotatably connected to the through hole. The roller mechanism is provided with a positioning structure to determine the height position of the roller. By providing an eccentric wheel and inserting the wheel axle into the eccentric hole, the height position of the roller can be adjusted by adjusting the position of the eccentric wheel. When the roller mechanism needs to be repaired or replaced, the eccentric block can be rotated to drive the wheel axle to rotate, thereby raising the axis height of the wheel axle so that the roller no longer contacts the outer ring of the fixed disk, thereby facilitating the removal or installation of the roller.

[0016] In some embodiments, the positioning structure includes a fixed block and a latch, wherein the fixed block is fixedly connected to the outer side of the corresponding bracket, the fixed block is provided with a second pin hole, and the wheel axle is provided with a first pin hole, and the latch can sequentially pass through the first pin hole and the second pin hole to determine the height position of the roller. The provision of the fixed block facilitates the latch to sequentially pass through the first pin hole provided on the wheel axle and the second pin hole provided on the fixed block to determine the position of the eccentric block, thereby determining the height position of the roller.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] 1. The reel is supported by a fixed disk and rotatably connected to the reel by a turntable. When the reel rotates, the turntable rotates synchronously to support the reel, preventing the reel from deflecting during rotation due to excessive reel diameter or uneven force on the reel, so that the reel can reel the cable smoothly.

[0019] 2. A lubrication structure is also provided to facilitate opening the oil passage through an electric switch valve before reeling the cable to lubricate the bearings installed on the device, reduce the friction of the bearings, and ensure smooth reeling of the cable.

[0022] 5. By setting the fixing block, it is convenient for the pin to pass through the first pin hole set on the wheel axle and the second pin hole set on the fixing block in sequence to locate the position of the eccentric block, and then locate the height position of the roller.
