DETAILED DESCRIPTION

[0023] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 A self-powered wire spreading pulley comprises a base 1, a winding shaft 2 is arranged inside the base 1, a drive box 8 is arranged on one side of the base 1, and further comprises:

[0025] A linkage shaft 10 is arranged at the lower end of the outer wall of the driving box 8;

[0026] The linkage assembly is arranged inside the driving box 8 and cooperates with the linkage shaft 10 to provide power for the winding shaft 2;

[0027] An adjustment component, arranged at the upper end of the bottom of the base 1, is used to control the operating power of the linkage shaft 10;

[0028] The mounting shell 18 is arranged at the center of the outer wall of the driving box 8. In this way, through the coordinated action of the adjustment components, the wire tension can be adjusted in real time to ensure that the wire always maintains appropriate tension during the deployment process to avoid being too tight or too loose.

[0029] Furthermore, two fixing rods are fixedly connected to the top of the base 1, and the two ends of the winding shaft 2 are rotatably connected to the inner wall of the base 1. The winding shaft 2 is fixedly connected to the inner side of the drive box 8 corresponding to one side. When in use, the winding shaft 2 wound on the outer surface of the winding shaft 2 is first passed through the inside of the threading buckle 6, and then the locking rod 17 is pulled to make the locking rod 17 run upward, so that the locking rod 17 loses the connection relationship with the linkage rod 16, and then the linkage rod 16 is pushed. When the linkage rod 16 is pushed, the linkage rod 16 drives the third gear 13 and the limit mother plate 14 When the third gear 13 slides with the limit mother plate 14, the limit mother plate 14 is meshed and connected with the limit male plate 15. At the same time, the third gear 13 is meshed and connected with the limit mother plate 14. When the wire needs to be spread out, the motor 9 is started and the first gear 11 is driven to rotate through the linkage shaft 10. Since the first gear 11 is meshed and connected with the second gear 12, the second gear 12 will also rotate accordingly. At the same time, the third gear 13 rotates at the same time. This gear transmission design effectively transmits the rotational power of the motor to the winding shaft 2, driving it to rotate, thereby starting the wire spreading process.

[0030] Furthermore, the mounting shell 18 is fixedly connected to the outer wall of the driving box 8, and a spring that applies downward elastic force is arranged inside the mounting shell 18. The bottom of the locking rod 17 extends into the mounting shell 18, and the lower end of the locking rod 17 is fixedly installed together with the spring. A section of the linkage rod 16 extends into the driving box 8 and is fixedly connected to the limiting mother plate 14. The linkage rod 16 is interactively connected with the driving box 8. Two limiting grooves are provided on the linkage rod 16 corresponding to the bottom of the locking rod 17, and the limiting mother plate 14 and the limiting male plate 15 are arranged correspondingly.

[0031] Furthermore, the outer wall of the driving box 8 is fixedly connected to the lower end of the motor 9 , the linkage shaft 10 is fixedly connected to the outer wall of the driving box 8 , and the output end of the motor 9 is hinged to the linkage shaft 10 .

[0032] Furthermore, the linkage assembly includes a first gear 11, a second gear 12 and a third gear 13. One side of the first gear 11 is rotatably connected to the outer wall of the base 1 through a connecting rod, the other side of the first gear 11 is hinged to the linkage shaft 10 through a connecting rod, the second gear 12 is rotatably connected to the outer wall of the base 1 through a connecting rod, and the first gear 11 and the second gear 12 are meshed and connected together.

[0033] Furthermore, the third gear 13 is fixedly connected to one end of the linkage rod 16 close to the limit mother plate 14 through a connecting rod, and when the linkage rod 16 is pushed, the third gear 13 is meshed and connected with the second gear 12 .

[0034] Furthermore, the adjustment component includes a linkage shell 3, a control switch 4, a movable rod 5, a threading buckle 6 and a linkage spring 7. The bottom of the linkage shell 3 is fixedly connected to the inner wall of the base 1, the lower end of the threading buckle 6 is slidingly connected to the inner wall of the linkage shell 3, the bottom of the movable rod 5 is fixedly connected to the top of the movable rod 5, the control switch 4 is fixedly connected to the top of the linkage shell 3, the top of the linkage spring 7 is fixedly connected to the bottom of the threading buckle 6, and the bottom of the linkage spring 7 is fixedly connected to the bottom inner wall of the linkage shell 3. When the tension needs to be increased, the speed of the motor 9 can be increased by controlling the switch 4 to make the winding shaft 2 rotate faster, thereby increasing the tension of the wire. On the contrary, when it is necessary to reduce the tension, the speed of the motor 9 can be reduced. In addition, the threading buckle 6 is used to fix the wire. When the wire tension changes, it will be transmitted to the movable rod 5 through the threading buckle 6. The movable rod 5 is connected to the linkage spring 7. The linkage spring 7 has a certain elastic force and can be extended and retracted according to the change of tension. When the wire tension is too large, the movable rod 5 will be subjected to downward pressure, causing the linkage spring 7 to compress and at the same time squeeze the control switch 4 to transmit this signal to the control switch 4. After receiving the signal, the speed of the motor 9 will be automatically reduced, thereby reducing the tension of the wire. On the contrary, when the tension is too small, the linkage spring 7 will stretch and push the movable rod 5 to move upward, and the control switch 4 will increase the speed of the motor 9. In this way, through the synergistic effect of the adjustment components, the real-time adjustment of the wire tension can be achieved to ensure that the wire always maintains appropriate tension during the unfolding process to avoid being too tight or too loose.

[0035] Working principle: When in use, first pass the winding shaft 2 wound on the outer surface of the winding shaft 2 through the inside of the threading buckle 6, then pull the locking rod 17 to make the locking rod 17 move upward, so that the locking rod 17 and the linkage rod 16 lose the connection relationship, and then push the linkage rod 16. When pushing the linkage rod 16, the linkage rod 16 drives the third gear 13 and the limit mother plate 14 to slide. When the third gear 13 and the limit mother plate 14 slide, the limit mother plate 14 is meshed and connected with the limit male plate 15. At the same time, the third gear 13 and The limit mother plate 14 is meshed and connected. When the wire needs to be spread out, the motor 9 is started, and the first gear 11 is driven to rotate through the linkage shaft 10. Since the first gear 11 is meshed and connected with the second gear 12, the second gear 12 will also rotate accordingly, and the third gear 13 rotates at the same time. This gear transmission design effectively transmits the rotational power of the motor to the winding shaft 2, driving it to rotate, thereby starting the wire spreading process. The control switch 4 is responsible for controlling the speed of the motor 9, thereby indirectly adjusting the spreading speed and tension of the wire. When the tension needs to be increased, the speed of the motor 9 can be increased by controlling the switch 4 so that the winding shaft 2 rotates faster, thereby increasing the tension of the wire. Conversely, when the tension needs to be reduced, the speed of the motor 9 can be reduced. In addition, the threading buckle 6 is used to fix the wire. When the wire tension changes, it will be transmitted to the movable rod 5 through the threading buckle 6. The movable rod 5 is connected to the linkage spring 7. The linkage spring 7 has a certain elastic force and can be extended and retracted according to the change of tension. When the wire tension is too large, the movable rod 5 will be subjected to downward pressure, causing the linkage spring 7 to be compressed and the control switch 4 to be squeezed at the same time, and this signal will be transmitted to the control switch 4. After receiving the signal, the speed of the motor 9 will be automatically reduced, thereby reducing the tension of the wire. Conversely, when the tension is too small, the linkage spring 7 will stretch and push the movable rod 5 to move upward, and the control switch 4 will increase the speed of the motor 9. In this way, through the synergistic effect of the adjustment components, real-time adjustment of the wire tension can be achieved to ensure that the wire always maintains appropriate tension during the unfolding process to avoid over-tightening or over-loosening.
