[0001] The invention relates to the technical field of cable repair, and in particular to a device for repairing a broken cable and preventing leakage. Background Art

[0002] During the use of cables, the insulation layer may be damaged due to weathering or external collisions. In order to prevent leakage at the damaged part, it is necessary to wrap insulating tape or apply insulating glue on the damaged part for insulation protection.

[0003] For example, after searching, the Chinese patent publication number CN112103865B discloses a compensating cable damaged gluing repair device, including a box body and a dust removal structure, a gluing structure and a limiting structure arranged at one end of the box body, the dust removal structure includes a fixed tube, a clamping groove, a sponge block, a first slider, a first spring, a second slider, a second spring, a ball, a first slide groove and a second slide groove, the fixed tube is threadedly connected to one end of the box body, the clamping groove is provided inside the box body, the first slide groove is provided inside the box body, the first slide groove is slidably connected to the first slider, one end of the first slider is fixedly connected to the first spring, and the other end of the first spring is fixedly connected to the fixed tube, one end of the first slider is fixedly connected to the sponge block, the second slide groove is provided inside the box body, and the second slide groove is slidably connected to the second slider.

[0004] The above patent has the following shortcomings: its structure is in the form of an overall circular hole, which means that when repairing the cable, the cable needs to be inserted into the device. If the cable lengths at both ends of the damage are long or both sides of the cable are connected to other devices or cables, it needs to be disassembled and then inserted for repair, so the convenience of use is poor.

[0005] To this end, the present invention provides a broken cable repair and leakage prevention device. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a broken cable repair and leakage prevention device.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A device for repairing a broken cable and preventing leakage, comprising a handle,

[0009] One end of the accommodating and connecting shell is connected to a repair shell via the accommodating and connecting shell, and an open repair component is movably arranged inside the repair shell;

[0010] The open repair assembly includes an open wheel and a tape roll connected to the inner side of the open wheel through a connecting piece, the plurality of circular arrays of position-limiting transmission wheel members are rotatably connected to the inner side of the repair shell, one side of the open wheel is provided with an opening, and the spacing between two adjacent groups of the position-limiting transmission wheel members is greater than the width of the opening;

[0011] The limit transmission wheel component includes a rotating shaft and a gear. The rotating shaft is rotatably connected to the inner wall of the repair shell, and the gear is fixedly installed on the outer wall of the rotating shaft. The open wheel is engaged with the inner side of the gear through a gear ring fixedly installed on its outer side.

[0012] Preferably: a driving assembly for driving rotating shaft 1 is provided on the inner side of the accommodating connecting shell, and the driving assembly includes crankshaft 1 and crankshaft 2 arranged in the same direction, crankshaft 2 is fixed to the end of one of the gears, crankshaft 1 is rotatably connected to the inner side of the accommodating connecting shell through a driving shaft, and the outer walls of crankshaft 1 and crankshaft 2 are rotatably connected by the same connecting rod.

[0013] Furthermore: an electric motor is fixedly mounted on the inner side wall of the accommodating connection shell, and the output shaft of the electric motor is coupled to the driving shaft through a synchronous assembly.

[0014] On the basis of the above scheme: a limiting assembly is arranged in the accommodating connecting shell, and the limiting assembly includes a rotating rod 1 fixed to a side wall of the crankshaft and a threaded shaft connected to the inner wall of the accommodating connecting shell by a thread, a rotating rod 2 is fixedly installed on the end surface of the threaded shaft, and limiting bosses are fixedly installed at both ends of the rotating rod 2, and the limiting bosses are movably matched with the rotating rod 1.

[0015] A better solution in the above solution is that a same torsion spring is buckled between the second rotating rod and the accommodating connection shell.

[0016] As a further solution of the present invention: a safety component is also arranged inside the accommodating connection shell, and the safety component includes a partition fixed to the inner wall of the accommodating connection shell and a limit block and a counterweight block respectively slidably connected to the inner wall of the accommodating connection shell.

[0017] At the same time, the limit block and the counterweight block are matched through the inclined surface.

[0018] As a preferred embodiment of the present invention: an electrode sheet 2 is fixed to the top outer wall of the partition, an electrode sheet 1 matching the electrode sheet 2 is fixed to the bottom of the counterweight, and the electrode sheet 1 and the electrode sheet 2 are connected in series in the power supply circuit of the motor.

[0019] At the same time, the limit block is slidably connected to the side wall of the accommodating connection shell through a sliding rod, the outer wall of the sliding rod is sleeved with a spring, and a pull ring is fixed to the end surface of the sliding rod located outside the accommodating connection shell.

[0020] As a better solution of the present invention: the connecting member includes a support shaft and a flange, the support shaft is rotatably connected to the flange, and the side wall of the open wheel is provided with a countersunk hole, and the support shaft and the flange are inserted into the countersunk hole and fixedly installed on the side wall of the open wheel.

[0021] The beneficial effects of the present invention are:

[0022] 1. The present invention provides an open wheel with an opening on one side, and then uses multiple sets of limiting transmission wheel parts to limit the open wheel, so that the damaged part of the cable can be directly placed inside the open wheel through the opening, and then repaired by multiple turns of winding and covering. Therefore, it is not limited by whether the repair cable is connected or not, or the length of the two ends, which increases the convenience of use.

[0023] 2. The present invention, by setting a limit assembly, utilizes the transmission matching characteristics of rotating rod 1 and rotating rod 2 to enable crankshaft 1 to rotate reliably. At the same time, when the winding is completed, the torsion force of the torsion spring can be utilized to rotate crankshaft 1, thereby ensuring that at the end of each operation and before the next operation, the opening can be reliably located at the opening of the repair shell, thereby further increasing the convenience of use.

[0024] 3. The present invention sets a safety component, which uses a limit block to elastically limit the counterweight block, and combines the contact state of electrode plate 1 and electrode plate 2 with the position of the counterweight block and the series connection of electrode plate 1 and electrode plate 2 with the motor, so that the motor can be automatically shut down when the device is out of hand, thereby increasing the safety of the device.

[0025] 4. The present invention sets the limit block and the counterweight block as single-sided inclined surfaces, so that after an abnormal slip-out situation occurs, the limit block and the counterweight block limit each other so that the counterweight block cannot be reset. At this time, manual operation is required to proceed to the next step of work, which further increases safety.

[0026] 5. In the present invention, when installing and disassembling the support shaft, the bolts connecting the flange can be removed to pull the support shaft out relative to the open wheel, and then the tape roll can be installed or removed, so that for the relatively small open wheel, the tape roll can be replaced more conveniently.

DETAILED DESCRIPTION

[0036] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] Embodiment 1:

[0039] A broken cable repair and leakage prevention device, such as Figure 1-8 As shown, it includes a handle 1, one end of the accommodating and connecting shell 2 is connected to a repair shell 3 through the accommodating and connecting shell 2, and an open repair component 4 is movably provided inside the repair shell 3.

[0040] The open repair component 4 includes an open wheel 7 and a tape roll 13 connected to the inner side of the open wheel 7 through a connecting piece 14. The position limiting transmission wheel components 6 are rotatably connected to the inner side of the repair shell 3 through multiple groups of circular arrays. An opening 11 is provided on one side of the open wheel 7, and the distance between two adjacent groups of the position limiting transmission wheel components 6 is greater than the width of the opening 11.

[0041] The limit transmission wheel component 6 includes a rotating shaft 8 and a gear 9. The rotating shaft 8 is rotatably connected to the inner wall of the repair shell 3, and the gear 9 is welded to the outer wall of the rotating shaft 8. The open wheel 7 is meshed with the inner side of the gear 9 through the gear ring 10 welded on its outer side.

[0042] The side wall of the handle 1 is provided with anti-slip grooves 12 .

[0043] When in use, the damaged part of the cable is placed on the axis of the open wheel 7 through the opening 11, and the insulating tape wound on the tape roll 13 is pulled out and adhered to the outside of the cable. Then the gear 9 is driven to rotate. The gear 9 can drive the open wheel 7 to rotate by engaging with the gear ring 10, thereby driving the tape roll 13 to rotate relative to the cable, so as to perform multiple turns of winding and covering repair on the damaged part of the cable.

[0044] The device is provided with an open wheel 7, one side of which is provided with an opening 11, and then the open wheel 7 is limited by multiple sets of limiting transmission wheel parts 6, so that the damaged part of the cable can be directly placed inside the open wheel 7 through the opening 11, and then a multi-turn winding and covering repair is performed, so that it is not limited by whether the repair cable is connected or not, and the length of the two ends, thereby increasing the convenience of use.

[0045] To solve the driver problem; Figure 2 As shown, a driving assembly 5 for driving the rotating shaft 1 8 is provided on the inner side of the accommodating connecting shell 2, and the driving assembly 5 includes a crankshaft 15 and a crankshaft 2 17 arranged in the same direction, and the crankshaft 2 17 is fixed to the end of one of the gears 9, and the crankshaft 15 is rotatably connected to the inner side of the accommodating connecting shell 2 through a driving shaft 18, and the crankshaft 15 and the outer wall of the crankshaft 2 17 are rotatably connected by the same connecting rod 16.

[0046] The inner wall of the accommodating connecting shell 2 is fixed with a motor 19 by bolts, and the output shaft of the motor 19 is matched with the drive shaft 18 through the transmission of the synchronization component 20. In this embodiment, the specific type of the synchronization component 20 is not limited, and it can be a belt drive, a chain drive or a gear drive. Preferably, the synchronization component 20 is a gear drive.

[0047] When the motor 19 is started, it can drive the drive shaft 18 to rotate through the synchronization assembly 20, thereby driving the crankshaft 15 to rotate, thereby driving the crankshaft 2 17 to rotate synchronously through the connecting rod 16, thereby driving the gear 9 to rotate.

[0048] In order to further solve the convenience problem; Figure 4 As shown, a limit position assembly 22 is arranged in the accommodating connection shell 2, and the limit position assembly 22 includes a rotating rod 23 fixed to the side wall of the crankshaft 15 and a threaded shaft 24 connected to the inner wall of the accommodating connection shell 2 by threads, and a rotating rod 26 is welded to the end surface of the threaded shaft 24, and both ends of the rotating rod 26 are welded with limit position bosses 27, and the limit position bosses 27 are movably matched with the rotating rod 23, and the same torsion spring 25 is buckled between the rotating rod 26 and the accommodating connection shell 2.

[0049] When the winding repair operation is performed, the rotating rod 1 23 rotates, and it drives the rotating rod 26 to rotate through the limiting boss 27, thereby driving the threaded shaft 24 to rotate. The threaded shaft 24 drives the rotating rod 26 to move to the side away from the rotating rod 1 23 through the threaded connection, until the limiting boss 27 is no longer in contact with the rotating rod 1 23, and the rotating rod 26 is rebounded by the torsion force of the torsion spring 25, and this cycle repeats until the winding repair is completed and the motor 19 is powered off. At this time, after the rotating rod 1 23 loses its power source, it will rotate due to the rebound torsion force of the torsion spring 25 until the torsion force of the torsion spring 25 is released and it returns to its natural state. At this time, the opening 11 is located at the opening of the repair shell 3.

[0050] The present device, by setting a limit assembly 22, utilizes the transmission cooperation characteristics of the rotating rod 1 23 and the rotating rod 2 26 to enable the crankshaft 15 to rotate reliably. At the same time, when the winding is completed, the torsion force of the torsion spring 25 can be utilized to rotate the crankshaft 15, thereby ensuring that after each operation is completed and before the next operation, the opening 11 can be reliably located at the opening of the repair shell 3, thereby further increasing the convenience of use.

[0051] To solve security issues; Figure 4 , 6 As shown in Figures 8, a safety component 21 is also provided inside the accommodating connection shell 2. The safety component 21 includes a partition 34 fixed to the inner wall of the accommodating connection shell 2 and a limit block 31 and a counterweight block 32 respectively slidably connected to the inner wall of the accommodating connection shell 2. The limit block 31 and the counterweight block 32 are matched through an inclined surface.

[0052] The top outer wall of the partition 34 is fixed with an electrode sheet 2 35 , the bottom of the counterweight 32 is fixed with an electrode sheet 1 33 that matches the electrode sheet 2 35 , and the electrode sheet 1 33 and the electrode sheet 2 35 are connected in series in the power supply circuit of the motor 19 .

[0053] The limit block 31 is slidably connected to the side wall of the accommodating connection shell 2 through a slide rod 29 , a spring 30 is sleeved on the outer wall of the slide rod 29 , and a pull ring 28 is fixed to the end surface of the slide rod 29 outside the accommodating connection shell 2 .

[0054] When the device slips out of hand, the tape stretching has viscous resistance, which makes the open wheel 7 have resistance when rotating relative to the cable. At this time, the device slips out of hand and the reaction force of the resistance will rotate around the cable, so that the counterweight 32 is subjected to centrifugal force, which overcomes the elastic limiting effect of the limit block 31 and moves outward, so that the electrode piece 1 33 is not in contact with the electrode piece 2 35, and the motor 19 is powered off. When it needs to be used again, the pull ring 28 can be pulled outward to reset the counterweight 32.

[0055] The device is provided with a safety component 21, which utilizes a limit block 31 to elastically limit the counterweight 32, and combines the contact state of the electrode piece 1 33 and the electrode piece 2 35 with the position of the counterweight 32, and the electrode piece 1 33 and the electrode piece 2 35 are connected in series with the motor 19, so that the motor 19 can be automatically shut down when the device is out of hand, thereby increasing the safety of the device.

[0056] In addition, the device sets the limit block 31 and the counterweight block 32 as single-sided inclined surfaces, so that after an abnormal slip-out situation occurs, the limit block 31 and the counterweight block 32 limit each other so that the counterweight block 32 cannot be reset. At this time, manual operation is required to proceed to the next step of work, which further increases safety.

[0057] When the present embodiment is in use, the damaged part of the cable is placed at the axis of the open wheel 7 through the opening 11, and the insulating tape wound on the tape roll 13 is pulled out and bonded to the outside of the cable, and then the motor 19 is started. When the motor 19 is started, it can drive the drive shaft 18 to rotate through the synchronization component 20, thereby driving the crankshaft 15 to rotate, thereby driving the crankshaft 2 17 to rotate synchronously through the connecting rod 16, thereby driving the gear 9 to rotate, and the gear 9 can drive the open wheel 7 to rotate by meshing with the gear ring 10, thereby driving the tape roll 13 to rotate relative to the cable, so as to perform a multi-turn winding and covering repair on the damaged part of the cable, and when the device is out of hand during use, the tape stretching has a viscous resistance, This causes the open wheel 7 to have resistance when rotating relative to the cable. At this time, the device is out of hand, and the reaction force of the resistance will cause it to rotate around the cable, so that the counterweight 32 is subjected to centrifugal force, and it overcomes the elastic limiting effect of the limit block 31 and moves outward, so that the electrode piece 1 33 is not in contact with the electrode piece 2 35, and the motor 19 is powered off. When it is needed to continue using it, the pull ring 28 can be pulled outward to reset the counterweight 32. At the same time, the winding repair is completed, and the motor 19 is powered off. At this time, after the rotating rod 1 23 loses its power source, it will rotate due to the rebound torque of the torsion spring 25 until the torque of the torsion spring 25 is released, and it returns to its natural state. At this time, the opening 11 is located at the opening of the repair shell 3.

[0058] Embodiment 2:

[0060] In this embodiment, when installing and disassembling the support shaft 36, the bolts connecting the flange 37 can be removed to pull the support shaft 36 out relative to the open wheel 7, and then the tape roll 13 can be installed or removed, so that for the relatively small open wheel 7, the tape roll 13 can be replaced more conveniently.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
