Description

Technical Field

[0001] The present application relates to the technical field of cable protection devices, and more specifically, to a cable anti-pulling protection device and a method of using the same. Background Art

[0002] Cables are a general term for items such as optical cables and electrical cables; they are mainly used for multiple functions such as controlling installation, connecting equipment, and transmitting electricity. They are common and indispensable in the process of building electrical construction.

[0003] In the related art, during the cable installation process, one end of the cable needs to be fixed and then pulled according to the set route. During the pulling process, if the pulling length reaches the actual length of the cable, continuing to pull will cause damage to the cable, increasing construction losses. In order to prevent the cable from being damaged during pulling, for example, a document with the prior art publication number CN216413772U provides a cable anti-pulling protection device, which fixes the cable by setting a cable inlet and a cable outlet and the cable moves after passing around a spring. If there is pulling, the deformed part of the spring will have a certain buffer space. If it is pulled excessively, the spring will contact the sensor rod after deformation. The sensor rod will sense and alarm after sensing, effectively avoiding the pulling damage of the cable.

[0004] Although the above-mentioned prior art solution can achieve the effect of alarming when excessive pulling is achieved through the sensing rod induction, the cable is wrapped around the outside of the spring. When the alarm is triggered, the springs are tightened by the cable and collectively move closer to the sensing rod. When the pulling is eliminated, due to the large friction between the cable and the spring, it is difficult for the cable to be rewound around the outside of the spring under the recovery of the spring, and the cable needs to be rewound around the outside of the spring, which makes it difficult for the cable to automatically reset and continue to perform anti-pulling protection.

[0005] In view of this, we propose a cable anti-pulling protection device and a method of using the same. Summary of the invention

[0006] 1. Technical issues to be solved

[0007] The purpose of the present application is to provide a cable anti-pulling protection device and a method of using the same, which solves the technical problem that the cable is difficult to automatically reset and continue to perform anti-pulling protection, and achieves the technical effect that the cable can automatically reset and continue to perform protection when the pulling is eliminated.

[0008] 2. Technical solution

[0009] The present application provides a cable anti-pulling protection device, comprising:

[0010] A shell, wherein sliding holes are provided on both sides of the shell, and buffer components for buffering cables are symmetrically arranged inside the shell corresponding to the sliding holes, and a buzzer for preventing over-pull alarm is fixedly arranged inside the shell, and the buffer component triggers the buzzer alarm, and a cover plate is arranged on the top of the shell;

[0011] A winding assembly for winding the cable, the winding assembly being fixedly disposed inside the housing and located between the symmetrically disposed buffer assemblies;

[0012] A wire retracting and releasing assembly is used to drive the wire winding assembly to retract and release the cable, and the wire retracting and releasing assembly drives the wire winding assembly to operate under the drive of the buffer assembly.

[0013] By adopting the above technical solution, the cable is passed through the interior of the two buffer components, and the excess part is wound and stored by the winding component, and then the cable and the buffer component are fixed. When the cable is subjected to pulling force, the cable drives the buffer component to move to buffer the pulling force, and the buffer component drives the retractable wire component to make the winding component retract and release the wound cable, so that the cable has sufficient length for buffering. When the buffer component moves to a certain extent driven by the cable, it triggers the buzzer inside the shell to alarm, thereby preventing continued pulling from causing damage to the cable. When the pulling is eliminated, the buffer component drives the cable to reset itself, and at the same time, the buffer component drives the winding component to re-tighten the retracted cable through the retractable wire component, so as to continue to protect the cable from pulling.

[0014] As an optional solution to the technical solution of the present application document, the buffer component includes a wire threading tube, a slip ring is slidably provided on the outside of the wire threading tube, the slip ring is fixedly provided on the inner side of the sliding hole, a cable fixing sleeve is fixedly provided on one end of the wire threading tube located on the outside of the outer shell, a wire pressing assembly for fixing the cable is provided inside the cable fixing sleeve, a connecting sleeve is fixedly provided on the other end of the wire threading tube, a spring A is provided on the outside of the wire threading tube between the connecting sleeve and the outer shell, cables are penetrated inside the wire threading tube, the cable fixing sleeve and the connecting sleeve, an alarm trigger is fixedly provided on the top of the connecting sleeve, and the alarm is triggered when the alarm trigger is close to the inner side of the outer shell.

[0015] By adopting the above technical scheme, the cable is passed through the connecting sleeve, the threading tube and the cable fixing sleeve. After the cable is wound through the winding assembly, it is fixed to the cable fixing sleeve through the wire pressing assembly. When the cable is pulled, the cable drives the cable fixing sleeve to move, so that the cable fixing sleeve drives the threading tube to slide on the inner side of the sliding hole through the slip ring. When the threading tube slides, it drives the alarm trigger on the top of the connecting sleeve to approach the inner side of the shell. At the same time, the buffer assembly drives the winding assembly to relax the cable wound on the outside through the retractable wire assembly, so that the cable fixing sleeve drives the excess cable to move after the relaxation, which is used to buffer the pulling. When the connecting sleeve compresses the spring A to a certain extent, the alarm trigger approaches the inner side of the shell to trigger the buzzer inside the shell to sound an alarm. When the pulling is released, the connecting sleeve is pushed under the action of the spring A to drive the threading tube to automatically reset, and the cable is pulled into the shell again under the drive of the cable fixing sleeve. At this time, the buffer assembly drives the retractable wire assembly to run in the reverse direction, so that the retractable wire assembly drives the winding assembly to re-tighten the retracted cable.

[0019] By adopting the above technical solution, when the connecting sleeve moves, the connecting sleeve drives the sliding rod to slide on the inner side of the connecting frame, and compresses the spring B through the limit plate, which can cooperate with the spring A to buffer the pulling force at the same time. When the connecting sleeve is reset, the sliding rod pulls the connecting sleeve to reset under the action of the spring B, thereby improving the overall buffering performance of the buffer assembly.

When the buffer assembly drives the take-up and pay-out assembly to operate, the take-up and pay-out assembly drives the winding shafts to approach each other to loosen the wound cable. When the take-up and pay-out assembly runs in the reverse direction, the excess cable can be tightened to prevent the cable from scattering inside the outer casing.

[0023] By adopting the above technical solution, when the buffer assembly drives the driving wheel to rotate, the driving wheel drives the inner slider to slide, so that the slider drives the winding shaft to slide on the inner side of the slide groove, thereby loosening the cable. When the driving wheel reverses, the driving wheel drives the slider to move away from each other, so that the slider drives the winding shaft to move away from each other to tighten the cable.

[0024] As an optional solution to the technical solution of the present application document, a gear is fixedly provided at the bottom of the driving wheel, and a rack A and a rack B are meshed on the outer side of the gear.

The cover plate is engaged with the limit stop through the handle, and a mobile power supply for powering the buzzer is fixedly arranged inside the shell, and a sound expansion hole is opened at the top of the cover plate corresponding to the buzzer.

[0027] By adopting the above technical solution, the cover on the top of the shell is opened before winding the cable, and the cover is assembled on the top of the limit block after the cable is wound.

[0038] (1) The present application adopts a buffer component to buffer the pulling of the cable and can drive the cable to automatically reset, thereby effectively solving the problem that the cable is difficult to automatically reset and continue to provide anti-pulling protection. When the cable is subjected to pulling force, the cable drives the buffer component to move to buffer the pulling force.

When the pulling is eliminated, the buffer component drives the cable to reset itself and can continue to provide anti-pulling protection for the cable.

[0039] (2) The present application sets a winding assembly inside the shell. When the buffer assembly moves driven by the cable, it will drive the winding assembly to retract and release the wound cable, so that the cable has sufficient length for buffering. When the pulling is eliminated, the buffer assembly drives the winding assembly through the retracting and releasing assembly to re-tighten the retracted cable, so as to prevent the cable from scattering inside the shell.

[0040] (3) The present application sets a wire retracting and releasing assembly between the buffer assembly and the winding assembly. When the buffer assembly moves driven by the cable, the driving wheel is driven to rotate, and the driving wheel drives the inner slider to slide, so that the slider drives the winding shaft to slide on the inner side of the slide groove, thereby loosening the cable. When the buffer assembly drives the cable to reset, the driving wheel is reversed, and the driving wheel drives the slider to move away from each other, so that the slider drives the winding shaft to move away from each other to tighten the cable. The structure is simple and it is easy to drive the winding assembly to retract and release the cable.

[0041] (4) The present application sets a gear at the bottom of the driving wheel. When one of the buffer components moves under the drive of the cable, it will drive rack A or rack B to slide, so that rack A or rack B drives the gear to rotate. When the gear rotates, it drives the driving wheel to drive the winding assembly to retract and release the cable, so that the cable can be pulled in both directions for buffering protection.

[0052] The present application is further described in detail below in conjunction with the accompanying drawings.

[0053] Reference Figure 1 , Figure 2 and Figure 3The embodiment of the present application discloses a cable anti-pulling protection device, including a shell 1, with sliding holes 11 on both sides of the shell 1, and two buffer components 2 for buffering pulling force are symmetrically arranged inside the shell 1 corresponding to the sliding holes 11. The cable passes through the inside of the buffer component 2, and the buffer component 2 runs under the pulling of the cable. A winding component 3 for winding the cable is arranged between the two buffer components 2 inside the shell 1. The winding component 3 retracts and releases the wound cable under the drive of the retractable wire component 4, and the retractable wire component 4 runs under the drive of the buffer component 2. A buzzer 13 for over-pull alarm is arranged inside the shell 1, and the buzzer 13 starts to alarm when triggered by the buffer component 2. A cover plate 12 is arranged on the top of the shell 1.

[0054] Pass the cable through the two buffer components 2, and wind the excess part through the winding component 3, and then fix the cable to the buffer component 2. When the cable is subjected to pulling force, the cable drives the buffer component 2 to move to buffer the pulling force. The buffer component 2 will drive the retractable wire component 4 to make the winding component 3 retract and release the wound cable, so that the cable has enough length for buffering. When the buffer component 2 moves to a certain extent driven by the cable, it will trigger the buzzer 13 inside the shell 1 to alarm, thereby preventing continued pulling from causing damage to the cable. When the pulling is eliminated, the buffer component 2 drives the cable to reset itself. At the same time, the buffer component 2 drives the winding component 3 to re-tighten the retracted cable through the retractable wire component 4, and the cable can continue to be protected against pulling.

[0055] Reference Figure 3 and Figure 4 The buffer assembly 2 includes a threading tube 21, which is slidably arranged on the inner side of the sliding hole 11 through a slip ring 22. A cable fixing sleeve 23 is fixedly arranged at one end of the threading tube 21 located on the outer side of the shell 1. A wire pressing assembly for fixing the cable is arranged inside the cable fixing sleeve 23. A connecting sleeve 24 is fixedly arranged at the other end of the threading tube 21. A spring A25 is arranged on the outer side of the threading tube 21 between the connecting sleeve 24 and the shell 1. An alarm trigger 27 is fixedly arranged on the top of the connecting sleeve 24. When the alarm trigger 27 is close to the inner side of the shell 1, the alarm is triggered.

[0056] The cable is passed through the connecting sleeve 24, the threading tube 21 and the cable fixing sleeve 23. After the cable is wound through the winding assembly 3, it is fixed to the cable fixing sleeve 23 through the wire pressing assembly. When the cable is pulled, the cable drives the cable fixing sleeve 23 to move, so that the cable fixing sleeve 23 drives the threading tube 21 to slide on the inner side of the sliding hole 11 through the slip ring 22. When the threading tube 21 slides, it drives the alarm trigger 27 on the top of the connecting sleeve 24 to move closer to the inner side of the housing 1. At the same time, the buffer assembly 2 drives the winding assembly 3 to relax the cable wound on the outside through the wire retracting assembly 4, so that the cable is fixed. The sleeve 23 drives the excess cable to move after relaxation, which is used to buffer the pulling. When the connecting sleeve 24 compresses the spring A25 to a certain extent, the alarm trigger 27 approaches the inner side of the shell 1 to trigger the buzzer 13 inside the shell 1 to sound an alarm. When the pulling is released, the spring A25 pushes the connecting sleeve 24 to drive the threading tube 21 to automatically reset, and the cable is pulled into the interior of the shell 1 again under the drive of the cable fixing sleeve 23. At this time, the buffer component 2 drives the wire retracting component 4 to run in reverse, so that the wire retracting component 4 drives the winding component 3 to re-tighten the retracted cable.

[0058] When the connecting sleeve 24 moves, the connecting sleeve 24 drives the sliding rod 262 to slide on the inner side of the connecting frame 261, and compresses the spring B264 through the limit plate 263, which can cooperate with the spring A25 to buffer the pulling force at the same time. When the connecting sleeve 24 is reset, the sliding rod 262 pulls the connecting sleeve 24 to reset under the action of the spring B264, thereby improving the overall buffering performance of the buffer assembly 2.

[0060] When the cable passes through the cable fixing sleeve 23 and is located inside the wire pressing ring 231, the wire pressing ring 231 is rotated at this time to press the cable tightly through the wire pressing ring 231, and then the pressing position of the wire pressing ring 231 is controlled by using a wrench in cooperation with the bolt head 232, and then the nut 234 on the outside of the screw rod 233 is rotated so that the nut 234 fixes the screw rod 233 and the cable fixing sleeve 23, thereby fixing the cable fixing sleeve 23 and the cable.

[0062] Before the cable is wound around the outside of the winding shaft 35, the winding shaft 35 is driven by the wire reel assembly 4 to be located at the end of the slide groove 34 that is away from each other. The stability of the winding shaft 35 on the inside of the slide groove 34 is ensured by the action of the wire reel assembly 4. When the buffer assembly 2 drives the wire reel assembly 4 to run, the wire reel assembly 4 drives the winding shafts 35 to approach each other to loosen the wound cable. When the wire reel assembly 4 runs in the reverse direction, the excess cable can be tightened to prevent the cable from being scattered inside the housing 1.

A slider 43 is slidingly provided on the inner side of the driving wheel 41 corresponding to the winding shaft 35. The slider 43 is fixedly provided at both ends of the winding shaft 35. When the driving wheel 41 rotates, it drives the winding shaft 35 to slide on the inner side of the slide groove 34.

[0064] When the buffer assembly 2 drives the driving wheel 41 to rotate, the driving wheel 41 drives the inner slider 43 to slide, so that the slider 43 drives the winding shaft 35 to slide on the inner side of the slide groove 34, thereby loosening the cable. When the driving wheel 41 reverses, the driving wheel 41 drives the slider 43 to move away from each other, so that the slider 43 drives the winding shaft 35 to move away from each other to tighten the cable.

[0066] When one of the buffer components 2 moves driven by the cable, it will drive the rack A45 or the rack B46 to slide, so that the rack A45 or the rack B46 drives the gear 44 to rotate. When the gear 44 rotates, it drives the driving wheel 41 to drive the winding component 3 to retract and release the cable.

Open the cover plate 12 on the top of the housing 1, pass the cable through the two buffer components 2 inside the housing 1, and then wind and store the excess cable between the buffer components 2 through the winding component 3, and then fix the cable to the cable fixing sleeve 23 in the buffer component 2 through the wire pressing component, and finally install the cover plate 12;

[0071] S2. When the cable is subjected to a pulling force, the cable drives the buffer assembly 2 to move to buffer the pulling force. The buffer assembly 2 drives the retractable cable assembly 4 to make the winding assembly 3 retract and release the wound cable, so that the cable has enough length for buffering;

[0072] S3, at this time, the connecting sleeve 24 in the buffer component 2 drives the alarm trigger 27 to approach the inner side of the housing 1. When the alarm trigger 27 and the retractable wire component 4 reach a certain distance, the buzzer 13 inside the housing 1 will be triggered to sound an alarm, thereby preventing the cable from being damaged by continued pulling;

[0073] S4, when the cable tension is removed, the buffer assembly 2 drives the cable to reset itself, and at the same time, the buffer assembly 2 drives the winding assembly 3 to re-tighten the retracted cable through the retracting assembly 4, and the cable can continue to be protected from pulling;

[0074] S5. At this time, the alarm of the buzzer 13 is cancelled, and the alarm can be sounded again when the cable is pulled again.

[0075] In summary, when the cable anti-pulling protection device disclosed in the embodiment of the present application is used, the cable is passed through the connecting sleeve 24, the threading tube 21 and the cable fixing sleeve 23, and then the cable is wound on the outside of the winding shaft 35 in the winding assembly 3. After the cable is wound through the winding assembly 3, it is fixed to the cable fixing sleeve 23 through the wire pressing assembly. When fixing, the wire pressing ring 231 is rotated to press the cable through the wire pressing ring 231, and then the pressing position of the wire pressing ring 231 is controlled by using a wrench and the bolt head 232, and then the nut 234 on the outside of the screw 233 is rotated so that the nut 234 fixes the screw 233 and the cable fixing sleeve 23 to fix the cable. When the cable is pulled, the cable drives the cable fixing sleeve 23 to move, so that the cable fixing sleeve 23 drives the threading tube 21 to slide on the inner side of the sliding hole 11 through the slip ring 22. At the same time, when the connecting sleeve 24 moves, the connecting sleeve 24 drives the slide bar 262 to slide on the inner side of the connecting frame 261, and compresses the spring B264 through the limit plate 263, which can cooperate with the spring A25 to buffer the pulling force at the same time. When the threading tube 21 slides, it drives the alarm trigger 27 on the top of the connecting sleeve 24 to approach the inner side of the shell 1. At the same time, the buffer component 2 drives the rack A45 or the rack B46 to slide, so that the rack A45 or the rack B46 drives the gear 44 to rotate. When the gear 44 rotates, it drives the driving wheel 41 to rotate. When the buffer component 2 drives the driving wheel 41 to rotate, the driving wheel 41 drives the inner slider 43 to slide, so that the slider 43 drives the winding shaft 35 to slide on the inner side of the slide groove 34, thereby loosening the cable so that the cable has enough length for buffering. When the connecting sleeve 24 compresses the spring A25 to a certain extent, the alarm trigger 27 approaches the inner side of the shell 1 to trigger the buzzer 13 inside the shell 1 to sound an alarm.

[0076] When the pulling is released, the connecting sleeve 24 is pushed by the spring A25 to drive the threading tube 21 to automatically reset. When the connecting sleeve 24 is reset, the sliding rod 262 pulls the connecting sleeve 24 to reset under the action of the spring B264. At this time, the cable is pulled into the interior of the housing 1 again under the drive of the cable fixing sleeve 23. At this time, the driving wheel 41 reverses, and the driving wheel 41 drives the slider 43 to move away from each other, so that the slider 43 drives the winding shaft 35 to move away from each other to tighten the cable. At the same time, the buzzer 13 cancels the alarm, and it can continue to be used for cable anti-pulling protection.
