[0019] With reference to the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14 to Fig. Figure 15 shows a preferred embodiment of the present utility model.

[0020] The present utility model provides an extendable product comprising a housing 10, wherein the housing 10 is provided with an extendable elongated component. Extendable products may include data cables for charging or data transmission, car chargers, power banks, dog leashes, and similar products.

[0021] In the extendable product described above, the combination of the housing and the elongated component allows the extension length of the component to be freely adjusted to various application scenarios, meeting diverse needs such as leashing pets, storing digital accessories, and everyday portable connections. For example, it allows for flexible adjustment of the extension length while walking and provides compact, tangle-free storage for data cables. With its adjustable length, ease of use, and convenient storage, it effectively eliminates the limitations of conventional extendable products, such as fixed lengths unsuitable for different scenarios, susceptibility to tangling and knotting, and cumbersome storage. Its simple structure and compact size ensure easy portability and use.

[0022] In this embodiment, the elongated component is a cable 100 for transmitting data or charging. Thus, this device functions as a data cable, with part of the cable 100 located inside the housing 10. Its extendable design allows the length of the cable 100 exposed outside the housing to be adjusted, which facilitates both storage and use.

[0023] The housing 10 is equipped with an electrical connector 300. This device thus functions as a charger, power bank, etc., with the charger being suitable for household use, car charging, and so on. The electrical connector 300 allows the cable 100 to connect to external circuits for charging. The extendable cable 100 significantly increases operational flexibility.

[0024] In particular, the housing 10 contains a battery. In this way, the device functions as a power bank, storing energy in its battery and transmitting it to the outside via the cable 100. The design of the extendable cable 100 significantly increases operational flexibility.

[0025] In this embodiment, the elongated component is a tow rope 20. It is cost-effective and extremely practical. This device is used for harnessing animals and for similar purposes.

[0026] The pull cord is arranged within the housing 10, with one end section of the pull cord extending outside the housing 10 to form an extension section 200. The length of the extension section 200 can be adjusted by an external force to achieve an extendable arrangement. When not in use, the pull cord 20 can thus be stored within the housing 10. During operation, the length of the extension section 200 can be adjusted by applying an external force, allowing for flexible length adjustment to meet the requirements of pet activity, charging, data transmission, and other functional needs.

[0027] In this embodiment, the housing 10 is provided with a storage arrangement 2, which is configured to store the pull rope and to automatically retract it. In this way, the configuration of the storage arrangement 2 enables the tidy storage and automatic retraction of the pull rope 20, eliminating the need for manual organization and significantly improving ease of use. The storage arrangement 2 facilitates the tidy organization of the pull rope 20 within the housing 10 and also reduces friction and wear. At the same time, it prevents the time-consuming reorganization required before the next use due to disorganized pull ropes 20, thus improving user-friendliness.

[0028] In particular, a central shaft 12 is provided within the housing 10, wherein the storage device 2 comprises a roller 30 and a helical spring 40, the roller 30 being movably mounted on the central shaft 12, an elastic section 31 being formed on a central part of the roller 30, the helical spring 40 being provided within the elastic section 31, one end of the helical spring 40 being connected to the central shaft 12, and another end of the helical spring 40 being connected to the roller 30; wherein an outer circumference of the roller 30 has an annular winding surface 33, the pull rope being wound onto the winding surface 33. In this way, a stable and reliable automatic storage structure is created by the coordination of the central shaft 12, the roller 30, and the helical spring 40.The elastic deformation and restoring force of the coil spring 40 provide a continuous, controllable force for the automatic retraction of the pull cord 20. The annular winding surface 33 on the outer circumference of the roller 30 provides a structured winding space for the pull cord 20 and ensures that the pull cord 20 does not overlap or knot during storage. This further improves the tidiness of storage and the stability of the device's operation.

[0029] A limiting shaft 34 is provided on the winding surface 33 of the roller 30, with an inner end of the pull rope 20 being mounted on the limiting shaft 34, and an outer end of the pull rope 20 extending outside the housing 10. Thus, the arrangement of the limiting shaft 34 ensures a secure connection between the pull rope 20 and the roller 30 and prevents relative slippage or loosening between the pull rope 20 and the roller 30 during extension or retraction. This guarantees the safety and reliability of the extension process.

[0030] In particular, the housing 10 is provided with a limiting structure 3; the limiting structure 3 is used to lock the rotation of the pulley 30 in order to secure a protruding length of the extension section 200. The limiting structure 3 locks the rotation of the pulley 30 and fixes the extension length of the extension section 200. This solves the problem of the single telescopic pull cord 20 tending to extend or retract unintentionally due to external forces or its own elasticity. Once the user has set the desired length, the locking function ensures a stable pull length. This prevents situations in which sudden movements of the pet could cause the extension section 200 to extend excessively and the pull cord 20 could pinch the pet when retracting.This allows for adaptation to pets of different sizes and activity levels, as well as to different user preferences regarding leash handling, and improves the adaptability of the device.

[0031] The limiting device comprises several limiting grooves 32 on the side of the roller 30, a movable button 50 slidably mounted on the housing 10, and a return spring 60. The housing 10 has a button opening 13, the lower part of the movable button 50 projecting through the button opening 13 into the housing 10 and forming a detent section 500.

[0032] The locking section 500 is located above the limiting groove 32, while the underside of the return spring 60 is fixed and the upper side of the return spring 60 rests against the movable button 50. A recessed groove 14 is formed on the side wall inside the housing 10. The movable button 50 has a pivot section 51 that can be deformed by pressure, the pivot section 51 being provided with an outwardly projecting embedding block 52.

[0033] During locking, pressing the movable button 50 and the pivot section 51 causes the pivot section 51 to deform and pivot. The movable button 50 moves downwards, causing the embedding block 52 to move through the button opening 13 and extend into the housing 10. The return spring 60 deforms under pressure, engaging the locking section 500 in the limiting groove 32. Under the spring force of the return spring 60, the movable button 50 moves upwards, engaging the embedding block 52 in the recessed groove 14 to achieve locking. The design of the embedding block 52 and the recessed groove 14 ensures continuous and stable limitation of the rotation of the roller 30.

[0034] After unlocking, pressing the movable button 50 and the pivot section 51 causes the pivot section 51 to oscillate and deform, allowing the movable button 50 to move downwards. The embedding block 52 disengages from the recessed groove 14. Under the force of the return spring 60, the movable button 50 moves upwards, allowing the embedding block 52 to pass through the button opening 13 and exit the housing 10, thereby disengaging the locking section 500 from the limiting groove 32.

[0035] Operating procedure: In use, a ring-shaped handle 16 of the housing 10 is grasped with one hand. The spring-loaded hook 21 is pressed to unlock it and then securely attached to the pet's collar or harness. The extension section 200 is pulled to drive the pull cord 20, which rotates the pulley 30 and deforms the coil spring 40 to store tension. Once the extension length is set as desired, the movable button 50 is pressed to engage the locking section 500 in the limiting groove 32 of the pulley 30. The embedding block 52 then engages in the recessed groove 14 to complete the locking mechanism. Should a length adjustment be required during use, the button is pressed again to release the lock. After use, the button is pressed to release the lock. The coil spring 40 then retracts and drives the pulley 30 to rotate.The pull cord 20 retracts automatically through a rope outlet opening 15 and is neatly pulled back into the housing 10. Finally, the hook 21 is released to detach it from the pet harness and hang it up for storage. The entire process is straightforward and therefore suitable for everyday situations when walking pets.

[0036] As in Fig. As shown in Figure 9, the movable button 50 has an elongated profile, its upper outer surface being formed integrally with a pivot section 51. This structure forms an elastically deformable, overhanging projection arm that extends along the longitudinal direction of the movable button 50. A gap is provided between this projection arm and the body of the button, which allows for inward pivoting when the button is pressed. An embedding block 52 projects from the outer surface of the pivot section 51.

[0037] In this embodiment, the housing 10 comprises two matching half-shells 11. The split structure of the housing 10 with two matching half-shells 11 facilitates assembly, maintenance and replacement of the internal components.

[0038] In particular, a hook 21 is formed at the end of the tow rope. The hook 21 at the end of the tow rope 20 allows for quick attachment or removal from a pet collar or harness, thus enabling convenient handling and increasing ease of use. The hook 21 has a robust structural connection that withstands the tensile forces that occur during a pet's daily activities, thereby reducing the risk of separation and ensuring the pet's safety during walks.

[0039] In particular, hook 21 is a spring-loaded pressure release mechanism that allows a detachable connection to the pet's collar or harness.

[0040] The housing 10 includes a ring-shaped handle 16. This facilitates one- or two-handed operation with comfortable handling and reduces hand fatigue during prolonged use. The ring-shaped structure also makes it easier to hang the device for storage.

[0041] The housing 10 is provided with a rope outlet opening 15, through which the extension section 200 extends outside the housing 10. The rope outlet opening 15 limits the range of motion of the pull rope 20, prevents entanglement due to disorderly movements of the pull rope 20 within the housing 10, and ensures smooth extension and retraction of the pull rope 20. The foregoing is only a preferred embodiment of the present invention and is not intended to limit the present utility model, nor does it imply that all modifications, equivalent replacements, improvements, etc., made within the spirit and principles of the present utility model are included in the scope of protection of the present utility model.
