Embodiment 1
[0028] Please refer to Figures 1-4 , a technical solution provided by the present utility model:
[0029] A low-voltage and weak-current cable with an automatic rewinding function includes a low-voltage and weak-current cable harness 3, and a rewinding box housing 10 arranged in the middle of the low-voltage and weak-current cable harness 3. The rewinding box housing 10 is set in a disc structure. A rewinding bin 5 is opened inside the rewinding box housing 10. A rotating shaft 6 is rotatably connected in the middle of the rewinding bin 5. The middle position of the low-voltage and weak-current cable harness 3 is wound around the rotating shaft 6. Two cable ports 2 communicating with the inside of the rewinding bin 5 are opened on the outer wall of the rewinding box housing 10. The two ends of the low-voltage and weak-current cable harness 3 respectively pass through the two cable ports 2 and extend out of the rewinding box housing 10.
[0030] Specifically, in the present utility model, the rewinding box housing 10 arranged in the middle of the low-voltage and weak-current cable harness 3 is set in a disc structure. A rewinding bin 5 is opened inside the rewinding box housing 10. A rotating shaft 6 is rotatably connected inside the rewinding bin 5. The rotating shaft 6 rotates to automatically wind the low-voltage and weak-current cable harness 3 extending outwards from both ends to the outside of the rewinding box housing 10, realizing the operation of automatic storage, without the need for manual winding by workers, which is time-consuming and laborious, and the winding efficiency is fast.
[0031] A rewinding box cover plate 1 is installed on the front end face of the rewinding box housing 10. The rewinding box cover plate 1 is a circular plate-shaped cover plate, which plays a role in protecting the internal components of the rewinding box housing.
[0032] A cover plate connection base 7 is arranged on the rear end face of the rewinding bin 5. A spring barrel 11 with a circular hole structure is opened in the middle of the cover plate connection base 7. The right end face of the rotating shaft 6 is rotatably connected to the center position of the spring barrel 11, which is convenient for the spring 9 to drive the rotating shaft 6 to rotate back.
[0033] A spring 9 is installed on the inner wall of the spring barrel 11. One end of the spring 9 is fixed to the surface of the rotating shaft 6. The rotation of the rotating shaft 6 in the rewinding bin 5 is driven by the spring 9 in the spring barrel 11 to rotate back. When a person uses this low-voltage and weak-current cable, first, the low-voltage and weak-current cable harness 3 will be pulled out to both ends of the rewinding box housing 10. During the process of pulling the low-voltage and weak-current cable harness 3, the rotating shaft 6 will be driven to rotate. During the rotation of the rotating shaft 6, the spring 9 in the spring barrel 11 will store energy. When the low-voltage and weak-current cable needs to be stored after use, the energy stored by the spring 9 drives the rotating shaft 6 to rotate back in the rewinding bin 5, thereby driving the low-voltage and weak-current cable harness 3 to wind automatically.
[0034] A bin partition 12 is arranged between the spring barrel 11 and the rewinding bin 5. The front end of the rotating shaft 6 passes through the bin partition 12 and extends into the rewinding bin 5, and the rotating shaft 6 is rotatably connected to the bin partition 12. The bin partition 12 separates the spring barrel 11 from the rewinding bin 5, so that the winding process of the low-voltage and weak-current cable harness 3 in the rewinding bin 5 will not affect the work in the spring barrel 11, and at the same time, the spring 9 in the spring barrel 11 will not affect the work in the rewinding bin 5 during the winding process.
[0035] On the top surface of the cover plate connection base 7, a number of connection bayonets 8 are provided. On the rear end face of the bin partition 12, a number of buckles 13 that are snap-fitted with the connection bayonets 8 are provided. The connection bayonets 8 and the buckles 13 are prior arts, which improves the installation firmness of the cover plate connection base 7. Any existing snap-fitting that can adapt to this application can be used as a replacement for the connection bayonets 8 and the buckles 13 of this application.
[0036] At the top of each low-voltage and weak-current cable harness 3 that passes through the outside of the take-up box housing 10, a low-voltage and weak-current cable connector 4 is provided, which is convenient for connecting the low-voltage and weak-current cable harness 3 and external devices.
[0037] Specifically, in the present utility model, the take-up box housing 10 is provided in the middle of the low-voltage and weak-current cable harness 3. The take-up box housing 10 is set as a disc structure. Inside the take-up box housing 10, a take-up bin 5 is provided. A rotating shaft 6 is rotatably connected inside the take-up bin 5. By rotating the rotating shaft 6, the low-voltage and weak-current cable harness 3 extending outwards from both ends to the outside of the take-up box housing 10 is automatically wound, realizing the operation of automatic storage, without the need for manual winding that is time-consuming and laborious, and the winding efficiency is fast.
[0038] Specifically, the rotation of the rotating shaft 6 in the take-up bin 5 in the present utility model is driven by a spring 9 in a spring chamber 11. When a person uses this low-voltage and weak-current cable, first, the low-voltage and weak-current cable harness 3 is pulled out towards both ends of the take-up box housing 10. During the process of pulling the low-voltage and weak-current cable harness 3, the rotating shaft 6 will be driven to rotate. During the rotation of the rotating shaft 6, the spring 9 in the spring chamber 11 will store energy. When the low-voltage and weak-current cable needs to be stored after use, the energy stored by the spring 9 drives the rotating shaft 6 to rotate in the take-up bin 5, thereby driving the low-voltage and weak-current cable harness 3 to wind automatically. This action does not require external motor drive or external power drive. By using the energy stored by the spring 9, the self-rotation of the rotating shaft 6 is realized, and the automatic winding of the low-voltage and weak-current cable harness 3 is realized, achieving the magical function of automatic storage.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
