[0002] With the advancement of science and technology, the use of portable multimedia audio-visual entertainment devices has become increasingly common, and headphones are an indispensable part of these devices. Existing headphones are mainly divided into wired headphones and wireless headphones. Although wireless headphones have advantages such as ease of use, wired headphones are still an irreplaceable accessory for entertainment devices due to their higher cost and the need for a power supply.

[0003] Chinese patent publication number "CN207603867U" discloses an earphone cable, including an earphone cable body, one end of which is connected to an earphone and the other end is connected to a plug. The earphone cable is provided with a volume adjustment device. The earphone cable includes a wire core and a sheathing layer. The wire core is located inside the sheathing layer. A plurality of protrusions are evenly distributed on the outer surface of the sheathing layer. A hydrophobic polymer layer is disposed between each protrusion. A protective layer for protecting the earphone cable is provided at the connection between the earphone cable and the earphone and the plug.

[0004] However, this headphone cable also has some shortcomings. Because the headphone cable connects to two headphones and the cable itself is quite long, the connection point of the long headphone cable is prone to bending during use. At the same time, when carrying the headphones, the connection point of the two headphone cables is also prone to getting tangled together. After a long period of tangling or bending, it is easy to break, thus reducing the lifespan of the headphone cable. Utility Model Content

A screw rod is threadedly connected to the inner side of the second screw hole. A connecting block is snapped into the top of the volume regulator, and a rotating shaft is rotatably connected to the top of the connecting block. The bottom end of the screw rod is fixedly connected to the top end of the rotating shaft.

[0008] As a preferred technical solution, the top of the first limiting plate is provided with a first screw hole, which penetrates the top of both the first limiting plate and the first telescopic rod. The inner side of the first screw hole is threaded with a first bolt, and the bottom end of the first bolt is threaded into the interior of the first telescopic rod through the first screw hole. The first limiting plate is threaded to the top of the first telescopic rod through the first screw hole and the first bolt.

[0009] As a preferred technical solution, a slot is provided on one side of the first limiting plate, and a matching block is fixedly connected to the other side of the second limiting plate. The block is engaged inside the slot, and the other side of the second limiting plate is engaged with one side of the first limiting plate through the slot and the block.

[0010] As a preferred technical solution, the bottom end of the second limiting plate is provided with a sliding groove that matches the second telescopic rod.

[0014] In summary, the present invention has the following main advantages:

[0015] During use, to prevent bending or tangling at the headphone cable connection point, the second limiting plate is first moved by sliding, engaging one side of the first limiting plate. This effectively limits the position of the headphone cable, preventing bending or tangling. Due to the presence of the first and second telescopic rods, when the user turns the screw, the shaft allows the end of the screw to rotate in place, causing the support plate to move the first limiting plate up or down. This allows adjustment of the limiting point of the headphone cable, adjusting the height of the first limiting plate to the user's desired position. This effectively improves the user's experience with the headphone cable and extends its lifespan. Attached Figure Description

[0021] Example

[0022] refer to Figures 1 to 4This embodiment of a high-toughness headphone cable includes a volume regulator 1, a headphone cable body 2 at the bottom of the volume regulator 1, an adjustment button 3 on the front of the volume regulator 1, a first telescopic rod 4 fixedly connected to the top of the volume regulator 1, a first limiting plate 5 threadedly connected to the top of the first telescopic rod 4, one side of the first limiting plate 5 being arc-shaped, a second telescopic rod 13 fixedly connected to the top of the volume regulator 1, a second limiting plate 14 slidably connected to the top of the second telescopic rod 13, and the second limiting plate 14... The other side is curved. The headphone cable 2 is located inside the first limiting plate 5 and the second limiting plate 14. The other side of the second limiting plate 14 is snapped into one side of the first limiting plate 5. A support plate 8 is fixedly connected to the front side of the first limiting plate 5. A second screw hole 9 is opened at the top of the support plate 8. A screw rod 10 is threaded into the inner side of the second screw hole 9. A connecting block 11 is snapped into the top of the volume adjuster 1. A rotating shaft 12 is rotatably connected to the top of the connecting block 11. The bottom end of the screw rod 10 is fixedly connected to the top end of the rotating shaft 12, so that... When in use, the headphone cable 2 can be connected to corresponding electronic products. Its adjustment button 3 can be used to adjust the headphone volume. To improve the service life of the headphone cable 2, the second limiting plate 14 is moved first and then snapped into one side of the first limiting plate 5. The two arc-shaped edges meet to form a circle that matches the headphone cable 2, thereby effectively limiting the position of the headphone cable 2 and preventing it from bending or tangling. The first telescopic rod 4 and the second telescopic rod 13 both include a movable rod and a sleeve rod. The movable rod is sleeved inside the sleeve rod. Due to the presence of the first telescopic rod 4 and the second telescopic rod 13, when the user turns the screw 10, the rotating shaft 12 can make the end of the screw 10 rotate in place, and the support plate 8 will drive the first limiting plate 5 to move up or down, thereby adjusting the limiting point of the headphone cable 2. Adjusting the height of the first limiting plate 5 to the user's desired position can effectively improve the user's experience with the headphone cable and also achieve the purpose of improving the service life of the headphone cable 2.

[0023] refer to Figure 1 and Figure 2 The top of the first limiting plate 5 is provided with a first screw hole 6, which passes through the top of both the first limiting plate 5 and the top of the first telescopic rod 4. The inner side of the first screw hole 6 is threaded with a first bolt 7, and the bottom end of the first bolt 7 is threaded into the interior of the first telescopic rod 4 through the first screw hole 6. The first limiting plate 5 is threaded to the top of the first telescopic rod 4 through the first screw hole 6 and the first bolt 7. Due to the presence of the first bolt 7, the position of the first limiting plate 5 can be effectively fixed by screwing in the first bolt 7, thereby preventing the first limiting plate 5 from shifting. When it needs to be disassembled, the first bolt 7 can be unscrewed from the first screw hole 6. This also facilitates the user's maintenance of the first limiting plate 5 in the future.

[0024] refer to Figures 1 to 3The first limiting plate 5 has a slot 16 on one side, and the second limiting plate 14 has a locking block 17 that matches the slot 16 fixedly connected to the other side. The locking block 17 is engaged inside the slot 16. The other side of the second limiting plate 14 is engaged to one side of the first limiting plate 5 through the slot 16 and the locking block 17. The bottom end of the second limiting plate 14 has a sliding groove 19 that matches the second telescopic rod 13. The second limiting plate 14 is slidably connected to the top of the second telescopic rod 13 through the sliding groove 19. A protrusion 18 is fixedly connected to one side of the second limiting plate 14. The protrusion 18 has an arc-shaped corner. Due to the opening of the sliding groove 19, the second limiting plate 14 can slide, so that the locking block 17 can be engaged in the slot 16 to limit the position of the second limiting plate 14. The protrusion 18 can be easily grasped by the user. The second limiting plate 14 can also be pulled off directly by pulling the protrusion 18, which also facilitates the user's later maintenance of the second limiting plate 14.

[0025] refer to Figure 1 A limiting block 22 is fixedly connected to one side of the volume regulator 1. An arc-shaped groove 23 matching the headphone cable 2 is provided on one side of the limiting block 22. Due to the opening of the arc-shaped groove 23, when the headphone cable 2 is not in use, the user can wrap it around the limiting block 22 along the arc-shaped groove 23, thereby effectively limiting the position of the headphone cable 2 to prevent the headphone cable 2 from getting tangled.

[0026] refer to Figure 1 and Figure 2 Protective pads 15 are provided on one side of the first limiting plate 5 and the other side of the second limiting plate 14. The protective pads 15 cover one side of the first limiting plate 5 and the other side of the second limiting plate 14. The earphone cable 2 is in contact with the protective pads 15. Due to the presence of the protective pads 15, which are made of rubber, they have good anti-slip ability and elasticity. While improving the positional stability of the earphone cable 2, they can also prevent the earphone cable 2 from being bumped on the inner side of the first limiting plate 5 and the second limiting plate 14.

[0027] refer to Figure 4The inner side of the headphone cable 2 is provided with an insulation layer 20, which is 5 mm thick and made of polyester tape. The inner side of the headphone cable 2 is provided with a reinforcing wire layer 21, which is 5 mm thick and located close to the inner side of the insulation layer 20. The reinforcing wire layer 21 is made of Kevlar fiber. Due to the presence of the insulation layer 20, the polyester tape material is a high-strength and high-toughness insulating material used in the headphone cable. By providing an additional insulation layer 20 between the conductor and the outermost insulating layer, it increases the insulation impedance withstand value of the cable, thereby improving its service life and stability. Due to the presence of the reinforcing wire layer 21, the Kevlar fiber material is a high-strength and high-modulus synthetic fiber with excellent wear resistance, tear resistance and corrosion resistance, which can effectively improve the toughness and service life of the headphone cable 2.

[0028] Operating principle and advantages: During use, the headphone cable 2 can be connected to corresponding electronic products. Its adjustment button 3 facilitates volume adjustment. To improve the lifespan of the headphone cable 2, the second limiting plate 14 is moved and snapped onto one side of the first limiting plate 5. The two curved edges meet to form a circle matching the headphone cable 2, effectively limiting its position and preventing bending or tangling. Due to the presence of the first telescopic rod 4 and the second telescopic rod 13, when the user turns the screw 10, the rotating shaft 12 allows the end of the screw 10 to rotate in place. When the support plate 8 moves, the first limiting plate 5 moves up or down accordingly, thereby adjusting the limiting point of the headphone cable 2. Adjusting the height of the first limiting plate 5 to the user's desired position effectively improves the user's headphone cable experience and extends the lifespan of the headphone cable 2. The presence of the first bolt 7 effectively fixes the position of the first limiting plate 5, preventing displacement. When it needs to be removed, simply unscrew the first bolt 7 from the first screw hole 6, facilitating future maintenance of the first limiting plate 5. The headphone cable 2 is protected by a protrusion 18, which facilitates gripping and allows the user to pull the second limiting plate 14 directly off, making it easier for the user to maintain it later. The arc-shaped groove 23 allows the user to wrap the headphone cable 2 around the limiting block 22 when not in use, effectively limiting its position and preventing it from becoming tangled. The protective pad 15, made of rubber, provides excellent anti-slip properties and elasticity, further enhancing the stability and positioning of the headphone cable 2. While ensuring safety, it also prevents the headphone cable 2 from being bumped or knocked inside the first limiting plate 5 and the second limiting plate 14. Due to the presence of the insulation layer 20, the polyester tape material is a high-strength and high-toughness insulation material used in the headphone cable. It increases the insulation impedance tolerance value of the cable by providing an additional insulation layer 20 between the conductor and the outermost isolation layer, thereby improving its service life and stability. Furthermore, due to the presence of the reinforcing wire layer 21, the Kevlar fiber material is a high-strength and high-modulus synthetic fiber with excellent wear resistance, tear resistance and corrosion resistance, which can effectively improve the toughness and service life of the headphone cable 2.
