Description

Technical Field

[0001] This utility model relates to the field of cable reel technology, and in particular to a cable reel that can be rotated at will. Background Technology

[0002] In today's world of widespread electronic devices, smartphones, tablets, and other portable devices have become essential for daily life and work, and data cables are crucial for their charging and data transfer. Retractable data cables, with their extendable nature, can be adjusted to the required length, avoiding the problems of traditional cables being too long and messy or too short and inadequate. Data retractable cable winders further optimize their use and management.

[0003] The primary function of existing retractable data cable reels is to provide neat storage space for retractable data cables. Through an internal winding mechanism, the retractable cable automatically retracts and neatly winds itself onto a spool when not in use, saving storage space and creating a tidier environment. When in use, a gentle pull on the cable end smoothly releases the desired length of cable, meeting the connection needs of various scenarios.

[0004] However, most existing cable reels have a fixed housing design, which prevents them from rotating freely after placement. In daily use, users operate electronic devices from various positions and angles, requiring them to retrieve the data retractable cable from different directions. Especially when retrieving it from the side or other non-frontal directions, the cable will come into contact with the housing outlet, which will wear down the outer sheath over time, reduce insulation performance, increase the risk of leakage, and threaten user safety. At the same time, users pull hard to overcome the obstruction, causing the cable to bend significantly at the outlet. This can cause the internal metal wires to fatigue, lose elasticity, and reduce conductivity. In severe cases, it can even break the wire, reducing the lifespan of the data cable.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] In one embodiment of this utility model, such as Figure 1-6 As shown, a freely rotatable cable reel is provided, including a housing, a base 20, and a rotating assembly. The housing includes an upper shell 10 and a lower shell 11. A telescopic cable assembly 40 is provided between the upper shell 10 and the lower shell 11. The base 20 is disposed on the lower shell 11, and an adhesive layer 21 for bonding to the contact surface is provided at the bottom end of the base 20. The rotating assembly includes a connecting block 30 disposed inside the lower shell 11 and a connecting rod 31 disposed on the base 20. One end of the connecting rod 31 can be rotatably connected to or detached from the connecting block 30.

[0039] 1. By setting up a rotating assembly consisting of a connecting block 30 and a connecting rod 31, the housing and the base 20 can rotate freely. No matter which direction the user takes the telescopic cable 46 from, excessive contact between the cable and the housing outlet can be avoided, effectively reducing wear on the cable sheath and ensuring the insulation performance of the cable. Furthermore, the free rotation of the housing can prevent the user from pulling the cable forcefully due to inconvenience, which could cause significant bending of the cable. This protects the structural integrity of the internal metal wires of the cable, maintains good conductivity, and effectively extends the service life of the telescopic cable 46.

[0040] 2. By adopting a detachable connection method in which the connecting block 30 and the connecting rod 31 can be rotatably connected or detached, users can remove the shell from the base 20 at any time according to their own needs and take the shell out for use without having to fix it to the base 20 alone. This provides users with a more flexible and diverse way of use, meets the needs of use in different scenarios, and improves the practicality and convenience of the product.

[0041] Preferably, the first design of the rotating component, such as Figure 3 As shown, the bottom end of the lower shell 11 is provided with an inwardly recessed first mounting groove. The connecting block 30 is fixedly connected in the first mounting groove, and the center of the connecting block 30 near the connecting rod 31 is provided with an internal thread 300a.

[0042] One end of the connecting rod 31 is fixedly connected to the center of the base 20, and the outer surface of the other end is provided with an external thread 31a corresponding to the internal thread 300a. The external thread 31a can be threaded to or detached from the internal thread 300a.

[0043] The connecting rod 31 is provided with an external thread 31a corresponding to the internal thread 300a. The connecting rod 31 and the connecting block 30 are detachably connected by the threaded connection. This connection method is simple to operate and the connection is stable. It can ensure that the housing can rotate freely on the base 20, so that users can take the telescopic cable 46 from different directions and avoid problems such as cable wear and bending. At the same time, it can also make it convenient for users to remove the housing from the base 20 for use when going out, thus improving the practicality and convenience of the cable reel.

[0044] Preferably, the second design of the rotating component, such as Figure 4 As shown, the bottom of the lower shell 11 is provided with an inwardly recessed second mounting groove. The connecting block 30 is fixedly connected to the second mounting groove. The connecting block 30 has a first connecting cavity 301b and a second connecting cavity 302b arranged sequentially from the inside to the outside at the end near the connecting rod 31. The inner diameter of the first connecting cavity 301b is larger than the inner diameter of the second connecting cavity 302b, and the inner diameter of the second connecting cavity 302b is larger than the outer diameter of the connecting rod 31.

[0045] The connecting rod 31 has a cylindrical structure. One end of the connecting rod 31 is fixedly connected to the center of the base 20, and the outer side of the other end is provided with an outwardly protruding snap-fit ​​block 31b. The outer wall of the second connecting cavity 302b is provided with an entry part 303b corresponding to the snap-fit ​​block 31b, and the snap-fit ​​block 31b snaps into the first connecting cavity 301b.

[0046] In this embodiment, the radius of the first connecting cavity 301b must be greater than the sum of the radius of the connecting rod 31 and the protruding width of the snap-fit ​​block 31b. The snap-fit ​​block 31b enters the first connecting cavity 301b along the inlet 303b on the connecting block 30 and engages with it, thus realizing another detachable connection method between the connecting rod 31 and the connecting block 30. This snap-fit ​​structure ensures a stable connection while allowing the connecting rod 31 to rotate relative to the connecting block 30, thereby enabling free rotation of the housing. This effectively solves the problem caused by the fixed housing of existing cable reels. Furthermore, this snap-fit ​​connection method facilitates quick disassembly and installation of the housing, meeting the needs of users traveling outside.

[0047] Preferably, the telescopic cable assembly 40 includes a fixed cable 45, a telescopic cable 46, and a reel. The fixed cable 45 is fixed between the upper housing 10 and the lower housing 11. The telescopic cable 46 is disposed within the reel and is rotatably connected between the upper housing 10 and the lower housing 11 via the reel. By providing the fixed cable 45, the telescopic cable 46, and the reel, the telescopic cable 46 can flexibly extend and retract within the reel, allowing users to adjust the cable length as needed. Simultaneously, the rotatable connection of the reel makes the extension and retraction of the telescopic cable 46 smoother, reducing tangling and wear during extension and retraction, further ensuring the performance and lifespan of the cable. Combined with the rotating function of the housing, it better meets the needs of users using electronic devices from different angles.

[0048] Furthermore, the reel includes a rotating wheel 41, a first fixing plate 42, and a second fixing plate 43. The rotating wheel 41 is located between the upper shell 10 and the lower shell 11, and a transmission assembly 44 is provided between the rotating wheel 41 and the upper shell 10. The first fixing plate 42 is located on the rotating wheel 41, and the telescopic cable 46 is located on the rotating wheel 41. The telescopic cable 46 and its circuit board on the rotating wheel 41 are fixed to the rotating wheel 41 by the first fixing plate 42. The second fixing plate 43 is located on the first fixing plate 42 and is used to fix the circuit board. The reel adopts a structure of a rotating wheel 41, a first fixing plate 42, and a second fixing plate 43. The rotating wheel 41 provides a fixed carrier for the telescopic cable 46 and the circuit board of the rotating wheel 41. The first fixing plate 42 ensures the stable placement of the telescopic cable 46 on the rotating wheel 41. The second fixing plate 43 can be used to fix the circuit board, making the internal structure of the reel more compact and reasonable. Furthermore, through the setting of the transmission component 44, the rotating wheel 41 can better realize the rotation function, thereby driving the extension and retraction of the telescopic cable 46, reducing the resistance of the cable during extension and retraction, reducing the risk of cable wear, and improving the service life of the cable.

[0049] Furthermore, a spring retaining block 411 is provided on the rotating wheel 41, and a spring is provided between the spring retaining block 411 and the rotating wheel 41. The function of the spring is to provide a retraction force after the telescopic cable 46 is pulled out. One end of the spring is fixed inside the rotating wheel 41, and the other end is connected to the telescopic cable 46. By setting the spring retaining block 411 and the spring, the telescopic cable 46 can automatically retract into the reel under the action of the spring, making it convenient for users to use and store.

[0050] Furthermore, the transmission assembly 44 includes a connecting cover 441 detachably connected to the rotating wheel 41, a self-locking rocker 442, a spring plate 443, and a gear block 444. The connecting cover 441 has a moving gear 445. The gear block 444 is located inside the upper housing 10. The self-locking rocker 442 is located between the moving gear 445 and the gear block 444, with one end of the self-locking rocker 442 engaging with the moving gear 445 and the top end of the self-locking rocker 442 engaging with the gear block 444. The spring plate 443 is located on the rotating wheel 41, outside the moving gear 445, and the other end of the self-locking rocker 442 is located inside the spring plate 443. By setting up a connecting cover 441, a self-locking swing member 442, a spring plate 443, and a gear block 444, the movement gear 445 cooperates with the self-locking swing member 442 and the gear block 444, and the spring plate 443 limits the self-locking swing member 442, achieving stable rotation and a self-locking function for the rotating wheel 41. When the user pulls out or retracts the telescopic cable 46, the transmission component 44 can accurately transmit power to the rotating wheel 41, ensuring smooth winding and unwinding of the telescopic cable 46. At the same time, the self-locking function can prevent the telescopic cable 46 from automatically retracting or being over-pulled out when not in use, improving the safety and reliability of the cable reel, reducing damage to the cable due to accidents, extending the cable's service life, and without affecting the overall rotation and detachable carrying characteristics of the cable reel.

[0051] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
