Description

Technical Field

[0001] This utility model relates to an audio cable, and more particularly to a durable, retractable audio cable. Background Technology

[0002] With the rapid development of audio technology and multimedia devices, audio cables, as a key component for transmitting sound signals, are crucial for ensuring high-quality sound transmission. Audio cables not only need to have good conductivity and shielding properties, but also need to be easy to use and store, and maintain a stable and reliable connection in different environments.

[0003] Traditional audio cables have a fixed length. Overly long cables can drag on the floor, affecting aesthetics and potentially damaging the cable. Overly short cables restrict placement options for devices. Frequently used audio cables, if not properly stored, can easily become tangled and knotted, affecting their lifespan and potentially leading to poor contact or breakage. Utility Model Content

[0004] To overcome the shortcomings of traditional audio cables with fixed lengths, which easily lead to the cable dragging on the ground and affecting its appearance, and are prone to tangling and knotting during winding, thus affecting the cable's lifespan, this utility model provides a durable retractable audio cable.

[0005] The technical solution of this utility model is as follows: a durable retractable audio cable, including a main plug, a connecting wire, a secondary plug, a collecting tube, and a winding mechanism. A collecting tube is provided at one end of the main plug, and a connecting wire is connected to the end of the main plug with the collecting tube. A winding mechanism is provided on the collecting tube. One end of the connecting wire passes through the collecting tube and is wound around the winding mechanism. The other end of the connecting wire away from the main plug passes through one side of the collecting tube and is connected to the secondary plug.

[0006] In one embodiment, the winding mechanism includes a winding reel and a spiral spring. The winding reel is rotatably arranged inside the collecting cylinder, and spiral springs are symmetrically arranged at both ends of the winding reel.

[0007] In one embodiment, the device further includes fixing pins and tension springs. A plurality of fixing pins are provided at equal intervals along the circumference of one end of the winding reel. The fixing pins slide through the winding reel and engage with the collecting cylinder. Tension springs are provided between the fixing pins and the winding reel.

[0008] In one embodiment, the device further includes a push ring, push rods, and a return spring. A plurality of push rods are provided at equal intervals along the circumference of the end of the collecting cylinder away from the main plug. The end of the push rods away from the collecting cylinder is connected to the push ring. A return spring is provided between the push ring and the collecting cylinder.

[0009] In one embodiment, a cleaning block is also included, and the collection cylinder is provided with a cleaning block.

[0010] In one embodiment, a retaining ring is also included, which is provided on the collection tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by winding and unwinding the connecting wire through the winding reel, and by engaging the fixing pin with the collecting tube, the length between the main plug and the auxiliary plug connecting wire is controlled, avoiding the problem of the connecting wire dragging on the ground due to excessive length, making storage neater and more convenient, and improving the convenience of use.

[0025] Example: A durable, retractable audio cable, such as Figures 1-6As shown, the device includes a main plug 1, a connecting wire 2, an auxiliary plug 3, a collecting cylinder 4, a take-up reel 5, a spiral spring 6, a fixing pin 7, a tension spring 8, a push ring 9, a push rod 10, a return spring 11, a cleaning block 12, and a retaining ring 13. A collecting cylinder 4 is located at the lower end of the main plug 1, and a connecting wire 2 is connected to the lower end of the main plug 1. The connecting wire 2 passes through the rear side of the collecting cylinder 4. A take-up reel 5 is rotatably mounted inside the collecting cylinder 4. Spiral springs 6 are symmetrically mounted at both ends of the take-up reel 5. The connecting wire 2 passes through the rear end of the collecting cylinder 4 and is wound around the take-up reel 5. One end of the connecting wire 2 is rotatably connected to the middle of the rear side of the take-up reel 5, and the other end is wound around the outside of the take-up reel 5 and passes through the side wall of the collecting cylinder 4 from the inside to the outside from the front end of the inner side. The front end of the connecting wire 2 passes through the front side of the collecting cylinder 4 and connects to the lower end of the auxiliary plug 3. The front end of the take-up reel 5 is equidistant from the outside along its circumference. Three fixing pins 7 are provided, with each fixing pin 7 spaced 120 degrees apart. A locking hole is provided at the front end of the inner side of the collection tube 4. The fixing pins 7 slide through the take-up reel 5 and engage with the locking hole at the front end of the inner side of the collection tube 4. A tension spring 8 is provided between each fixing pin 7 and the take-up reel 5. Each tension spring 8 is wound around the corresponding fixing pin 7. Push rods 10 are provided at equal intervals along the circumference of the front end of the collection tube 4, corresponding to the number of locking holes. The push rods 10 slide through the front side of the collection tube 4 and are located corresponding to the locking holes. The rear end of the push rods are connected to a push ring 9. A return spring 11 is provided between the push ring 9 and the collection tube 4. A cleaning block 12 is provided at the front end of the inner side of the collection tube 4. The end of the connecting wire 2 away from the main plug 1 passes through the middle of the cleaning block 12 and through the front side of the collection tube 4. A plastic locking ring 13 is installed on the outside of the collection tube 4 by bolts.

[0026] When using the audio cable, first insert the main plug 1 into the main device, then pull the auxiliary plug 3 outwards. At the same time, the auxiliary plug 3 pulls the connecting cable 2, causing the connecting cable 2 to extend outwards. Simultaneously, the reel 5 rotates within the collecting drum 4, feeding the cable. The spiral spring 6 twists, and as the reel 5 rotates, the retaining pins 7 engage with the locking holes on the inner wall of the collecting drum 4, securing the reel 5 and controlling the length between the main plug 1 and the auxiliary plug 3. The auxiliary plug 3 can then be inserted into the auxiliary device. After use, first unplug the main plug 1 and the auxiliary plug 3, then press the push ring 9. The push ring 9 presses the push rod 10 forward, causing the push rod 10 to slide through the collecting drum 4. The push rod 10 passes from the outside to the inside of the collecting drum 4. The locking pin 7 is pushed out of the locking hole, releasing the locking pin 7 from the limiting fixation of the winding reel 5. Simultaneously, the winding reel 5 rotates and resets under the torque of the spiral spring 6, winding up the connecting cable 2. The connecting cable 2 then enters through the through hole on the right side of the front end of the collecting tube 4, and passes through the cleaning block 12 for surface cleaning, removing dust and water stains to ensure the interior is dry and clean. While the connecting cable 2 is winding, it pulls the auxiliary plug 3 closer to the collecting tube 4. When the connecting cable 2 is fully wound, the lower end of the auxiliary plug 3 is inserted into the through hole on the right side of the front end of the collecting tube 4, and the body of the auxiliary plug 3 is locked onto the retaining ring 13. This allows control over the length of the connecting cable 2 between the main plug 1 and the auxiliary plug 3, preventing the connecting cable 2 from dragging on the ground due to excessive length, making storage neater and more convenient. This not only extends the lifespan of the audio cable but also improves ease of use.

[0027] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
