Description

Technical Field

[0001] This application relates to the field of cable reel technology, and in particular to a telescopic cable reel. Background Technology

[0002] In wire winding applications, a cable reel is a device used for the efficient storage, routing, and management of power cords, data cables, or hoses. It neatly winds long spools of cable onto a spool, effectively protecting the spool from stretching, abrasion, and trampling, extending its lifespan, and significantly improving the working environment and operational safety.

[0003] For existing equipment, during winding or unwinding operations, the existing equipment lacks automatic guidance and wire arrangement functions, and relies entirely on operators to manually wind the wire into the storage shell, which is not convenient to operate. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a telescopic cable reel that solves the problem of inconvenient operation, which relies entirely on operators manually winding the cable into the storage housing.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a telescopic retractable reel, including a housing, an outlet on the outer side of the housing, a limiting component rotatably disposed inside the housing, a coil on the limiting component, the output end of the coil being connected to the outlet, and a rotating component inside the housing for automatically reeling the coil into the housing.

[0006] Furthermore, the storage shell includes an upper shell and a lower shell. A connecting hole is provided on one side of the upper shell, and a connecting shaft is fixedly connected to the inner side of the lower shell. The connecting shaft communicates with the connecting hole of the upper shell. The rotating assembly includes a rotating disk, a connecting cylinder, and a spring. The connecting cylinder is fixedly connected to one side of the rotating disk. A slot is provided on the arc surface of the connecting cylinder. The spring is located inside the connecting cylinder. The outer end of the spring is engaged in the slot of the connecting cylinder. The inner end of the spring is fixedly connected to the connecting shaft. The connecting shaft communicates with the connecting cylinder. The rotating disk is rotatably connected to the connecting shaft. The inner end of the coil is fixedly connected to the rotating disk.

[0007] Furthermore, the limiting component includes a wire reel and a rotating block. The rotating block is rotatably mounted on the connecting shaft, and the wire reel is rotatably mounted on the inner side of the upper shell. An annular groove is provided on the side of the wire reel near the upper shell. A connecting post is fixedly connected to the side of the rotating block near the wire reel. The connecting post is slidably connected in the annular groove. An arc-shaped locking block is provided in the annular groove of the wire reel. The wire coil is clamped between the wire reel and the rotating disk. The wire coil is rotatably mounted on the connecting shaft.

[0008] Furthermore, a PCB board is rotatably mounted on the connecting shaft, and the PCB board is located between the upper shell and the reel.

[0009] Furthermore, the output end of the coil adopts a Type-C interface.

[0010] Furthermore, a limiting block is fixedly installed at the end of the coil away from the housing, and the limiting block abuts against the outlet of the housing.

[0011] In summary, this application includes at least one of the following beneficial technical effects: In use, users simply pull the reel, which then rotates smoothly on the limiting component, pulling out the desired length of reel from the outlet. After use, the built-in rotating component automatically activates, quickly and neatly retracting the reel into the storage case. This achieves the convenient operation of "pull to use, release to retract," significantly improving efficiency and user experience.

[0012] When the user pulls the spool outwards, the spool rotates, causing a fixed rotating disc to rotate as well. The rotating disc transmits the rotational force to the internal spring through a connecting cylinder, forcing the spring to tighten and converting the user's pulling force into elastic potential energy (i.e., stored energy). When it's time to rewind, the user simply releases the spool. The compressed spring releases its stored potential energy, driving the connecting cylinder and rotating disc to rotate in opposite directions, thus automatically and quickly rewinding the spool back into the storage housing. This achieves rapid and automatic spool retraction, greatly improving ease of use. Attached Figure Description

Detailed Implementation

[0015] The present application will be further described in detail below with reference to the accompanying drawings.

[0016] Example, refer to Figures 1-3A telescopic cable reel includes a housing 1 with a cable outlet on its outer side. A limiting component 2 is rotatably mounted inside the housing 1, and a cable reel 3 is mounted on the limiting component 2. The output end of the cable reel 3 is connected to the cable outlet. A rotating component 4 is located inside the housing 1 to automatically reel the cable reel 3 back into the housing 1. In use, the user simply pulls the cable reel 3, which then rotates smoothly on the limiting component 2, pulling the desired length of cable reel 3 out from the cable outlet. After use, the built-in rotating component 4 automatically activates, quickly and smoothly retracting the cable reel 3 back into the housing 1. This achieves convenient "pull to use, release to reel" operation, significantly improving efficiency and user experience.

[0017] The storage shell 1 includes an upper shell 11 and a lower shell 12. A connecting hole is provided on one side of the upper shell 11. A connecting shaft 13 is fixedly connected to the inner side of the lower shell 12, and the connecting shaft 13 communicates with the connecting hole of the upper shell 11. The rotating assembly 4 includes a rotating disk 41, a connecting cylinder 42, and a spring 43. The connecting cylinder 42 is fixedly connected to one side of the rotating disk 41. A slot 421 is provided on the arc surface of the connecting cylinder 42. The spring 43 is disposed inside the connecting cylinder 42, with its outer end engaged in the slot 421. The inner end of the spring 43 is fixedly connected to the connecting shaft 13, which communicates with the connecting cylinder 42. The rotating disk 41 is rotatably connected to the connecting shaft 13, and the coil 3 is rotatably mounted on the connecting shaft 13. When the user pulls the coil 3 outwards, the coil 3 rotates, causing the rotating disk 41 fixed to it to rotate. The rotating disc 41 transmits rotational force to the internal spring 43 via the connecting cylinder 42, forcing the spring 43 to wind up and converting the user's pulling force into elastic potential energy (i.e., energy storage). When it is time to reel in the cord, the user simply releases the coil 3, and the compressed spring 43 releases its stored potential energy, driving the connecting cylinder 42 and the rotating disc 41 to rotate in opposite directions, thereby automatically and quickly rewinding the coil 3 back into the storage housing 1. This achieves rapid and automatic retraction of the coil 3, greatly improving the convenience of use.

[0018] The limiting component 2 includes a coil wheel 21 and a rotating block 22. The coil wheel 21 is rotatably mounted on the connecting shaft 13, and the rotating block 22 is rotatably mounted inside the upper shell 11. An annular groove 211 is formed on the side of the coil wheel 21 closest to the upper shell 11. A connecting post 23 is fixedly connected to the side of the rotating block 22 closest to the coil wheel 21. The connecting post 23 is slidably connected within the annular groove 211. An arc-shaped locking block 24 is provided within the annular groove 211 of the coil wheel 21. The coil 3 is clamped between the coil wheel 21 and the rotating disk 41. When the coil 3 is pulled outward, the coil wheel 21 rotates accordingly, causing its annular groove 211 to slide relative to the connecting post 23 fixed to the rotating block 22. When the connecting post 23 slides to and abuts against the arc-shaped locking block 24, the movement is locked. At this point, the coil 3 reaches the preset pull-out length limit, achieving precise positioning during pull-out. During winding, driven by the rotating component 4, the coil wheel 21 rotates in the opposite direction, and the connecting post 23 slides away from the arc-shaped locking block 24 and resets along the annular groove 211, allowing the coil 3 to be smoothly retracted into the housing. This "positioning-unlocking" mechanism effectively prevents the coil 3 from being pulled out excessively, improving the standardization and convenience of operation.

[0019] A PCB board 14 is rotatably mounted on the connecting shaft 13, and the PCB board 14 is located between the upper shell 11 and the reel 21. When using the device, an opening can be made on the outside of the upper shell 11. By setting the PCB board 14, the electronic connection terminal of the PCB board 14 can be located at the opening of the upper shell 11 and used to connect other components, thereby improving the working efficiency of the device.

[0020] The output of cable reel 3 uses a Type-C interface. The Type-C interface has become the mainstream standard for modern electronic devices (such as smartphones, tablets, and laptops). Using this interface ensures that the cable reel can serve the vast majority of user devices, achieving "one cable for multiple uses" and greatly expanding the product's applicable scenarios. A limiting block 31 is fixedly installed at the end of the coil 3 away from the storage shell 1, and the limiting block 31 abuts against the outlet of the storage shell 1. When the coil 3 is wound up, as the coil 3 is gradually stored in the storage shell 1, the winding is completed when the limiting block 31 abuts against the outlet of the storage shell 1, and the limiting block 31 prevents the coil 3 from being completely wound into the storage shell 1.

[0021] Working principle: When the user pulls the coil 3 outward, the coil 3 rotates, causing the fixed rotating disk 41 to rotate as well. The rotating disk 41 transmits the rotational force to the internal spring 43 through the connecting cylinder 42, forcing the spring 43 to wind up tightly. This converts the user's pulling force into elastic potential energy. The connecting post 23 slides within the annular groove 211 of the coil wheel 21. When it slides to the arc-shaped locking block 24, the coil 3 is released. When it is time to rewind the coil, the user simply releases the coil 3. The compressed spring 43 releases its stored potential energy, driving the connecting cylinder 42 and the rotating disk 41 to rotate in opposite directions. The connecting post 23 slides within the annular groove 211 of the coil wheel 21, moving away from the arc-shaped locking block 24. When the limiting block 31 contacts the outlet of the storage shell 1, the coil is rewound. This automatically and quickly winds the coil 3 back into the storage shell 1, improving the ease of use of the device.

[0022] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
