Description

Technical Field

[0001] The utility model relates to the field of cable retraction and release, in particular to a cable retraction and release device. Background Art

[0002] With the development of the technology and services of the State Grid, the production and life of all walks of life are becoming more and more dependent on electricity, so the reliability, timeliness and effectiveness of power supply are becoming more and more demanding. Especially during special hours or special periods of the day, due to the increase in peak power consumption or aging of the line, it is easy to cause line faults and tripping, which requires the power supply company's emergency repair personnel to arrive in time and strive to repair and restore power supply as soon as possible. When the fault is large and the power supply cannot be restored in the first time, it is necessary to connect to a temporary power supply.

[0003] However, the lines connected to the power supply are messy, so a cable rack is needed to organize the messy cable lines. There are various cable reels, cable rollers, cable pay-off racks and other products on the market, but their designs cannot fix the cables. When pulling the cables, the cable ends are easy to fall off the cable reel, resulting in messy cable lines and easy cable entanglement.

[0004] The existing patent (authorization announcement number: CN 218619672 U) discloses a cable retracting and releasing device, including an outer frame, a rotating shaft and a plurality of partitions. The cables are wound around the rotating shaft, and a plurality of different cables are separated by the partitions. The ends of the cables are passed through the fixing holes on the partitions, and the ends of the cables are fixed to the partitions with bolts, which effectively prevents the cable ends from escaping from the retracting and releasing device, causing the cable lines to be messy and the cables to be entangled. The circumferentially arranged fixed shafts are connected by arc-shaped steel bars, which increases the bearing capacity of the fixed shafts and effectively prevents the fixed shafts from being bent due to excessive weight of the cables. A guide wheel is arranged on one side of the outer frame. In order to keep the outer frame placed stably, a stabilizing leg is arranged on the side away from the guide wheel to effectively ensure the stability of the outer frame.

[0005] However, the above technical solution still has certain shortcomings. The rotating shaft has no locking device, and the rotating shaft can rotate freely on the inner wall of the outer frame. When the cable is released to a suitable length, the rotating shaft cannot be fixed to stop the cable from being released. After retracting the cable, if the end of the cable is forgotten to be fixed in the fixing hole, the rotation of the rotating shaft will drive the cable to rotate and release the cable. The function is single and the use is inconvenient. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] A cable retracting device, such as Figure 1-3As shown, it includes a U-shaped frame 100, the inner wall of the U-shaped frame 100 is rotatably connected to a rotating shaft 101, the outer wall of the rotating shaft 101 is provided with multiple groups of brackets 102, the ends of the multiple groups of brackets 102 are provided with hollow rollers 103, and the outer wall of the U-shaped frame 100 is provided with a locking mechanism 200;

[0029] The locking mechanism 200 includes a control box 201. The side wall of the U-shaped frame 100 is provided with the control box 201. One end of the rotating shaft 101 extends to the interior of the control box 201. A rectangular groove is opened at the end of the rotating shaft 101 extending to the interior of the control box 201, and a rectangular rod 202 is slidably connected to the inner wall of the rectangular groove. A gear 203 is provided at the end of the rectangular rod 202 away from the rectangular groove. Two groups of tooth blocks 204 are provided on the inner wall of the control box 201, and the two groups of tooth blocks 204 are meshed with the gear 203. A crank 205 is provided on the outer wall of the gear 203, and one end of the crank 205 extends to the outside of the control box 201.

[0030] When the cable is stopped from being retracted or released, it is only necessary to push the crank 205 to drive the gear 203 to engage with the tooth block 204. At this time, the gear 203 cannot rotate, that is, the rectangular rod 202 cannot rotate, that is, the shaft 101 cannot rotate, that is, the hollow drum 103 cannot rotate, which prevents the shaft 101 from rotating by itself through the bracket 102 to drive the hollow drum 103 to rotate, causing the cable to spread out. When it is necessary to release the cable, it is only necessary to pull the crank 205 backwards to drive the gear 203 to separate from the tooth block 204. At this time, the gear 203 can be rotated, that is, the gear 203 can be rotated by turning the crank 205, the gear 203 drives the shaft 101 to rotate through the rectangular rod 202, and the shaft 101 drives the hollow drum 103 to rotate through the bracket 102, thereby releasing the cable on the hollow drum 103, or the cable can be directly pulled out at this time. The arrangement of the bracket 102 and the hollow drum 103 reduces the weight of the device, which is convenient for transportation or relocation.

[0031] Please refer to Figure 1-5The inner wall of the rectangular rod 202 is provided with a fixing mechanism 300, and the fixing mechanism 300 includes a card block 301. The inner wall of the rectangular rod 202 is slidably connected with multiple groups of card blocks 301. The inner wall of the rectangular rod 202 is provided with multiple groups of partitions 302. The outer wall of the multiple card blocks 301 close to each other is provided with a limit spring, and one end of the limit spring is connected to the outer wall of the partition 302. The inner wall of the rectangular groove is provided with multiple groups of card grooves 303, and the multiple groups of card grooves 303 are respectively matched with the multiple groups of card blocks 301. The multiple groups of card blocks 301 are mutually connected. A pull rod is provided on the outer wall of the side close to each other, and the outer walls of the multiple groups of pull rods are respectively slidably connected to the inner walls of the multiple groups of partitions 302, the inner wall of the rectangular rod 202 is rotatably connected to a turntable 305, the outer wall of the turntable 305 is rotatably connected to multiple groups of connecting rods, and one ends of the multiple groups of connecting rods are respectively rotatably connected to the ends of the multiple groups of pull rods, a turning handle 306 is fixedly connected at the center of the outer wall of the turntable 305, and one end of the turning handle 306 extends to the outside of the crank 205, and the inner wall of the turning handle 306 is rotatably connected to the inner wall of the crank 205.

[0032] When the crank 205 is pushed or pulled, the rectangular rod 202 will be driven to slide in the rectangular groove. To prevent the crank 205 from accidentally sliding and causing the gear 203 to accidentally separate or mesh with the tooth block 204, the block 301 is inserted into the slot 303 to prevent the rectangular rod 202 from moving. When the rectangular rod 202 needs to be moved, it is only necessary to rotate the turning handle 306 first. The turning handle 306 drives one end of the two sets of connecting rods to rotate through the turntable 305, and the other end of the connecting rod can pull the block 301 into the inner wall of the rectangular rod 202 through the pull rod. At this time, the block 301 is separated from the slot 303, and the rectangular rod 202 can be moved. When the gear 203 is driven to move to mesh or separate with the tooth block 204, it is only necessary to loosen the turning handle 306, and the limit spring can push the block 301 into the slot 303. At this time, the rectangular rod 202 is fixed, that is, the gear 203 cannot move, thereby avoiding the accidental movement of the crank 205.

[0033] Please refer to Figure 1 Two groups of baffles 104 are provided on the outer wall of the hollow drum 103 , and multiple groups of fixing rings 105 are provided on the outer walls of the two groups of baffles 104 .

[0034] The baffle 104 is provided so that the cable fibers can be placed outside the hollow drum 103, and the fixing ring 105 is provided so that the end of the cable can be fixed.

[0035] Please refer to Figure 1 The bottom end of the U-shaped frame 100 is rotatably connected to a plurality of sets of universal wheels, and a push rod is provided on the outer wall of one side of the U-shaped frame 100 away from the control box 201.

[0036] The setting of the universal wheel makes it easy to move the cable, and the setting of the push rod makes it convenient for the user to push the U-shaped frame 100.

[0037] During use, when you stop retracting or releasing the cable, you only need to push the crank 205 to drive the gear 203 to engage with the tooth block 204. At this time, the gear 203 cannot rotate, that is, the hollow drum 103 cannot rotate, which prevents the shaft 101 from rotating and causing the cable to spread out. When you need to release the cable, you only need to pull the crank 205 backwards to drive the shaft 101 to rotate by turning the crank 205, thereby releasing the cable, or you can directly pull out the cable. It is easy to use.
