DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1: Please refer to Figures 1-5 , a wear-resistant and anti-winding earphone wire, including an outer shell 1, an internally movably connected winding shaft 14 at the inside of the outer shell 1, a gear disk 2 fixedly connected to the rear end of the outside of the winding shaft 14, a connecting wire 3 wound around the outside of the winding shaft 14, a split wire 7 arranged on the right side of the connecting wire 3, and a winding limit structure arranged at the top of the outer shell 1;

[0027] The winding limit structure includes a rotating block 13, a limit card slot 21 and a connecting block 24. A rotating handle 15 is fixedly connected to the front end of the winding shaft 14, and a connecting block 24 is fixedly connected to the top end of the outer shell 1. A limit rod 26 is movably connected inside the connecting block 24. A limit block 22 is fixedly connected to the bottom end of the limit rod 26, a rotating block 13 is fixedly connected to the top end of the limit rod 26, and clamping blocks 23 are fixedly connected to the upper and lower ends on the left and right sides of the limit rod 26. A limit card slot 21 is opened inside the connecting block 24, and sliding grooves 25 are opened at the front and rear ends inside the connecting block 24;

[0028] A headset head 9 is fixedly connected to the right side of the wire splitter 7. Tooth blocks are machined on the outside of the gear disc 2. The limit block 22 is embedded inside the tooth blocks, the clamping blocks 23 are embedded inside the limit card slot 21, and the limit card slot 21 slides up and down inside the sliding groove 25;

[0029] Specifically, as Figure 1 and Figure 4 shown, rotate the rotating block 13. The rotating block 13 drives the limit rod 26 to rotate so that the clamping blocks 23 rotate into the inside of the sliding groove 25. Then pull up the rotating block 13. The rotating block 13 drives the limit rod 26 to rise so that the clamping blocks 23 at the bottom ends on both sides of the limit rod 26 rise into the inside of the connecting block 24. Then rotate the rotating block 13 again to make the clamping blocks 23 rotate into the inside of the limit card slot 21. After that, rotate the rotating handle 15. The rotating handle 15 drives the winding shaft 14 to wind the connecting wire 3 to prevent the headphone wires from being wound together and affecting the service life of the headphone wires. After the winding is completed, lower the limit block 22 again between the tooth blocks outside the limit block 22 to fix the gear disc 2. Fixing the gear disc 2 can prevent the winding shaft 14 from accidentally rotating.

[0030] Embodiment 2: A first protective shell 4 is fixedly connected to the left side of the outer shell 1, a second protective shell 12 is fixedly connected to the right side of the outer shell 1. A braided net 8 is arranged outside the wire splitter 7. A second protective sleeve 10 is arranged on the right side outside the braided net 8. A first protective sleeve 5 is arranged on the left side outside the connecting wire 3. A protective pad 16 is fixedly connected to the inner side wall of the first protective sleeve 5. A reserved groove 6 is opened at the front end inside the second protective sleeve 10;

[0031] Specifically, as Figure 1 、 Figure 2 and Figure 3 shown, the first protective sleeve 5 and the second protective sleeve 10 are installed at the edges of the wire splitter 7 and the connecting wire 3 through the reserved groove 6. The protective pads 16 inside the second protective sleeve 10 and the second protective sleeve 10 can protect the edges of the wire splitter 7 and the connecting wire 3. The first protective shell 4 and the second protective shell 12 can conveniently protect the interfaces and the headset head 9. The braided net 8 outside the wire splitter 7 can prevent the wire splitter 7 and the connecting wire 3 from being worn, thereby increasing the wear resistance of the wire splitter 7 and the braided net 8.

[0032] Embodiment 3: A limit frame 11 is externally arranged on the branch wire 7. A partition plate 20 is fixedly connected at the middle position inside the limit frame 11. Limit clamping plates 17 are arranged at the upper and lower ends inside the partition plate 20. Springs 18 are fixedly connected between the limit clamping plates 17 and the partition plate 20. Rolling grooves are formed on the inner side walls of the limit clamping plates 17, and balls 19 are arranged inside the rolling grooves. The limit clamping plates 17 are arranged outside the branch wire 7, and the limit frame 11 slides left and right outside the branch wire 7 through the limit clamping plates 17.

[0033] Specifically, as Figure 1 and Figure 4 shown, the two groups of branch wires 7 are respectively arranged between the limit clamping plates 17. The springs 18 can clamp and limit the branch wires 7 through their own elasticity. When it is necessary to adjust the tightness of the branch wires 7, the limit frame 11 is pulled. The limit frame 11 slides left and right outside the branch wires 7. The balls 19 can reduce the friction between the limit clamping plates 17 and the branch wires 7, so that the branch wires 7 can move conveniently and the wear of the branch wires 7 can be reduced.

[0034] Working principle: When the utility model is in use, the first protective sleeve 5 and the second protective sleeve 10 are installed at the edges of the branch wire 7 and the connecting wire 3 through the reserved grooves 6. The protective pads 16 inside the second protective sleeve 10 and the second protective sleeve 10 can protect the edges of the branch wire 7 and the connecting wire 3. The first protective shell 4 and the second protective shell 12 can conveniently protect the interfaces and the earphone heads 9. The braided mesh 8 outside the branch wire 7 can prevent the branch wire 7 and the connecting wire 3 from being worn, so that the wear resistance of the branch wire 7 and the braided mesh 8 can be increased. The two groups of branch wires 7 are respectively arranged between the limit clamping plates 17. The springs 18 can clamp and limit the branch wires 7 through their own elasticity. When it is necessary to adjust the tightness of the branch wires 7, the limit frame 11 is pulled. The limit frame 11 slides left and right outside the branch wires 7. The balls 19 can reduce the friction between the limit clamping plates 17 and the branch wires 7, so that the branch wires 7 can move conveniently and the wear of the branch wires 7 can be reduced. When it is necessary to store the connecting wire 3, the rotating block 13 is rotated. The rotating block 13 drives the limit rod 26 to rotate, so that the clamping block 23 rotates into the inside of the sliding groove 25. Then the rotating block 13 is pulled upward. The rotating block 13 drives the limit rod 26 to rise, so that the clamping blocks 23 at the bottom ends on both sides of the limit rod 26 rise into the inside of the connecting block 24. Then the rotating block 13 is rotated again to make the clamping block 23 rotate into the inside of the limit clamping groove 21. After that, the rotating handle 15 is rotated. The rotating handle 15 drives the winding shaft 14 to wind the connecting wire 3, preventing the earphone wires from being wound together and affecting the service life of the earphone wires. After the winding is completed, the limit block 22 is lowered again between the teeth outside the limit block 22 to fix the toothed disc 2.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
