Description

Technical Field

[0001] The utility model relates to the technical field of cable reels, in particular to a cable reel with an anti-loosening structure. Background Art

[0002] Cable reels, also commonly known as cable drums or cable reels, are important auxiliary equipment widely used in fields such as construction, stage and studio, energy, industrial production, urban transportation, and aerospace. Their main function is to conveniently retract and release cables, protect them, and extend their service life.

[0003] When reeling in and out the cable, a cable reel is required. After the existing cable reel has completed reeling the cable, a set of pressure rods at the bottom will press the cable on the reel to limit the position of the cable. However, this limiting method can only limit one position of the cable on the reel, and the limiting effect is poor, and it cannot effectively prevent the cable on the reel from loosening. Utility Model Content

[0004] The purpose of the utility model is to provide a cable reel with an anti-loosening structure to solve the problem in the background art that the existing cable reel cannot effectively limit the cable.

[0005] To achieve the above object, the utility model provides the following technical solution: a cable reel with an anti-loosening structure, comprising: a base and a limiting rod, the top of the base is fixedly connected to a bracket, a motor is installed on one side of the bracket, and the output end of the motor is fixedly connected to a winding roller,

[0006] The interior of the base is movably connected to a handle through a bearing, one end of the handle is fixedly connected to the first bevel gear, the outer side of the first bevel gear is meshed with the second bevel gear, the top of the second bevel gear is fixedly connected to a threaded rod, and the end of the threaded rod close to the second bevel gear is movably connected to the base through a bearing, the outer side of the threaded rod is threadedly connected to a rack plate, both sides of the rack plate are meshed with the first driving gear, and the outer side of the first driving gear is meshed with the first driven gear, both sides of the first driving gear and the first driven gear are movably connected to the fixed plate through a central shaft and a bearing, and the bottom of the fixed plate is fixedly connected to the base.

[0007] Preferably, a connecting frame is fixedly connected to one side of the first driven gear, a sliding groove is provided on one side of the connecting frame, and the sliding groove is slidably connected to the limiting rod.

[0009] Preferably, a guide groove is provided inside the rack plate, and the guide groove is slidably connected to the guide rod, and the bottom of the guide rod is fixedly connected to the base.

[0010] Preferably, a first synchronous wheel is fixedly connected to the outer side of the motor output shaft, a synchronous belt is sleeved on the outer side of the first synchronous wheel, a second synchronous wheel is sleeved on one side of the synchronous belt, and a second driving gear is fixedly connected to one side of the second synchronous wheel.

[0011] Preferably, the outer side of the second driving gear is meshedly connected to the second driven gear, and one side of the second driving gear and the second driven gear are fixedly connected to a cleaning roller, the outer side of the cleaning roller is wrapped with a cleaning sponge, and the other side of the second driven gear is movably connected to the bracket through a central shaft and a bearing.

[0013] Compared with the prior art, the beneficial effect of the cable reel with an anti-loosening structure is as follows: by rotating the handle to drive the bevel gear set to rotate, the bevel gear set will drive the threaded rod and the rack plate to perform threaded transmission, driving the rack plate to move upward, and the rack plate will drive the second pressure plate to approach the cable on the winding roller when moving, and mesh with the first driving gear on both sides, so that the first driven gear and the connecting frame are reversed, driving the first pressure plate to approach the cable on the winding roller, and pressing the cable. While driving the winding roller to rotate and rewind the cable, the motor will also drive the first synchronous wheel to rotate. The first synchronous wheel can drive the second synchronous wheel to rotate through the synchronous belt, and the second synchronous wheel can drive the second drive gear to mesh with the second driven gear. The second drive gear and the second driven gear will each drive a group of cleaning rollers to rotate in the opposite direction. When the cable is reeled, it will pass between the two groups of cleaning rollers, and the two groups of cleaning rollers will clean the surface of the cable.

[0014] 1. When reeling in and out the cable, a cable reel is required. When limiting the cable that has been wound up on the reel, the bevel gear set is driven to rotate by turning the handle. The bevel gear set drives the threaded rod and the rack plate to perform threaded transmission, driving the rack plate to move upward. When the rack plate moves, it not only drives the second pressure plate toward the cable on the reel, but also engages with the first driving gear on both sides, causing the first driven gear and the connecting frame to reverse, and the first pressure plate on one side of the connecting frame will also approach the cable on the reel to press the cable tightly. In this way, the above operation can facilitate multi-point limiting of the cable on the cable reel to prevent the cable from loosening.

[0015] 2. When reeling in and out the cable, a cable reel is required. When the motor drives the reel to rotate and reel in the cable, it also drives the first synchronous wheel to rotate. The first synchronous wheel can drive the second synchronous wheel to rotate through the synchronous belt. The second synchronous wheel can drive the second drive gear to engage with the second driven gear. The second drive gear and the second driven gear will each drive a set of cleaning rollers to rotate in opposite directions. When reeling in, the cable will pass between the two sets of cleaning rollers. The two sets of cleaning rollers will clean the surface of the cable. The above operation can facilitate the cleaning of the cable during reeling. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] When the cable is wound up, the first driving gear 10 is meshed with the first driven gear 11, so that the first driven gear 11 rotates, and the first driven gear 11 drives the connecting frame 12 to reverse, so that the first pressing plate 14 on one side of the connecting frame 12 is also close to the cable on the winding roller 4;

[0026] In this way, when the handle 5 is rotated, the second pressure plate 17 and the first pressure plate 14 will move synchronously to tighten the cable on the winding roller 4. After the first pressure plate 14 contacts the cable, it will squeeze the spring 15 on one side. The first pressure plate 14 can slide inside the connecting frame 12 through the limiting rod 13. The retractable first pressure plate 14 can make up for the distance difference generated when the second pressure plate 17 and the connecting frame 12 move.

The first synchronous wheel 19 can drive the second synchronous wheel 21 to rotate through the synchronous belt 20. The second synchronous wheel 21 can drive the second driving gear 22 to mesh with the second driven gear 23.
