Description

Technical Field

[0001] This invention relates to the field of optical communication equipment technology, specifically a portable cable storage box. Background Technology

[0002] In the construction and operation of optical communication networks, the handling and deployment of optical communication cables (such as fiber optic patch cords, optical cables, signal cables, etc.) directly affects construction efficiency and cable lifespan. Existing methods for handling optical communication cables and related equipment suffer from the following prominent problems:

[0003] 1. Disorganized storage and easy cable damage: Traditional storage methods often use simple coils or direct winding, which lack a classified storage structure for cables. This makes them prone to tangling and knotting. Fiber optic cables are also prone to damage to the fiber core due to excessive bending angles, squeezing, and collisions during winding, affecting signal transmission quality. Although some storage boxes have storage space, they lack layered isolation and curvature protection structures, making it inconvenient to retrieve cables of different specifications after they are mixed together.

[0004] 2. Cumbersome cable winding and unwinding operation: Existing cable winding and unwinding devices mostly rely on motor drive or complex transmission structure, which limits the application scenarios. Manual winding requires multiple people or the use of tools, resulting in low operation efficiency. In addition, there are no cable protection measures at the cable outlet, and the cable surface is easily worn.

[0005] 3. Lack of reliable stopping mechanism and poor safety: Most storage devices do not have a dedicated stopping structure. After the cable is unwound, the winding reel is prone to rotate due to the cable's rebound force, causing the cable to loosen. A few structures with stopping function use threaded locking or complex buckle designs, which cannot achieve quick unlocking. Summary of the Invention

[0006] To address the problems in the prior art, the present invention provides a portable cable storage box.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a portable cable storage box, including a box body, a cable storage assembly inside the box body, the cable storage assembly including a first spool bracket and a second spool bracket, a spool is fixedly connected between the first spool bracket and the second spool bracket, a ratchet ring is fixedly connected to the side wall of the spool by bolts, and a stop groove is provided at the upper end of the ratchet ring, and a cable is wound on the spool;

[0008] A cam assembly is fixedly connected to the second reel bracket. The cam assembly includes a mounting base, a sliding groove inside the mounting base, and a cam movably mounted inside the sliding groove. The upper end of the cam is correspondingly engaged in a stop groove, and a spring is fixedly connected between the lower end of the cam and the bottom of the sliding groove.

[0009] The second reel bracket is provided with a safety buckle, which includes two symmetrically arranged outer locking blocks at the front end, and the outer locking blocks are correspondingly locked in the stop slot;

[0010] The second reel support has a center seat at its center, and a rotating seat is rotatably connected to the center seat, with the other end of the rotating seat fixedly connected to the reel.

[0011] Specifically, limiting blocks are symmetrically provided on the lower sidewall of the cam.

[0012] Specifically, a first reinforcing rod arranged in a star-shaped structure is fixedly connected between the central seat and the second scroll bracket, and a second reinforcing rod arranged in a square-shaped structure is fixedly connected between the first reinforcing rods.

[0013] Specifically, the front end of the safety buckle is provided with two symmetrically arranged inner blocks between the outer blocks, and the inner blocks are located on the second reinforcing rod on the upper side of the second reel bracket.

[0014] Specifically, the cam assembly is fixedly connected to the second reinforcing rod located at the upper end of the rotating seat by bolts.

[0015] Specifically, the rotating base is symmetrically provided with two rotating handles.

[0016] Specifically, a storage slot is provided at the center of the rotating base.

[0017] Specifically, the side wall of the housing is provided with a rotating port corresponding to the rotating seat and a locking port corresponding to the safety buckle.

[0018] Specifically, the lower end of the side wall of the box is provided with a cable outlet, and a cable baffle located above the cable outlet is fixedly connected to the box.

[0019] The beneficial effects of this invention are as follows: This invention does not rely on motor drive or complex transmission structures. A single person can complete the cable winding operation using only the symmetrical handles on the rotating base, without the need for multiple people or additional tools, making it suitable for various scenarios such as outdoor construction and temporary maintenance. The rotating port design on the housing allows for direct control of the reel rotation from outside the housing, making the winding process efficient and labor-saving. During cable unwinding and winding, the damping effect formed by the ratchet ring and cam assembly ensures even force distribution and reduced pulling force during unwinding. During winding, the winding speed can be limited to prevent the cable from tangling and knotting due to excessive winding speed, significantly improving the efficiency of wiring and retrieval. During transportation, storage, and when the cable is unwinding to the required length, the safety buckle can quickly engage with the stop groove of the ratchet ring, forming a rigid mechanical lock that completely secures the reel, preventing the reel from rotating or loosening due to cable rebound. Compared to traditional threaded locking or complex buckle structures, this safety buckle can be directly inserted and removed for unlocking, making operation simple and quick without additional tools, improving operational flexibility during construction.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1-7As shown, a portable cable storage box of the present invention includes a box body 1, inside which a cable storage assembly is provided. The cable storage assembly includes a first reel bracket 2 and a second reel bracket 3. A reel 21 is fixedly connected between the first reel bracket 2 and the second reel bracket 3. A ratchet ring 34 is fixedly connected to the side wall of the reel 21 by bolts, and the upper end of the ratchet ring 34 is provided with a stop groove 341. A cable 211 is wound on the reel 21. A cam assembly 4 is fixedly connected to the second reel bracket 3. The cam assembly 4 includes a mounting base 41. The mounting base 41 has a sliding groove 42 inside, and a cam 43 is movably mounted inside the sliding groove 42. The upper end of the cam 43 is correspondingly locked in the stop groove 341, and a spring 44 is fixedly connected between the lower end of the cam 43 and the bottom of the sliding groove 42. The second scroll bracket 3 is provided with a safety buckle 5, which includes two symmetrically arranged outer locking blocks 51 at the front end, and the outer locking blocks 51 are correspondingly locked in the stop groove 341. The second scroll bracket 3 has a center seat 31 at the center, and a rotating seat 6 is rotatably connected to the center seat 31. The other end of the rotating seat 6 is fixedly connected to the scroll 21.

[0031] Specifically, symmetrical limiting blocks 431 are provided on the lower side wall of the cam 43. The slide groove 42 has a cross-shaped structure, with the upper port diameter being smaller than the middle port diameter. The limiting blocks 431 are used to limit the position of the cam 43.

[0032] Specifically, a first reinforcing rod 32 arranged in a star-shaped structure is fixedly connected between the center seat 31 and the second reel bracket 3, and a second reinforcing rod 33 arranged in a square-shaped structure is fixedly connected between the first reinforcing rods 32. Two symmetrically arranged inner locking blocks 52 are located between the outer locking blocks 51 at the front end of the safety buckle 5. The inner locking blocks 52 correspond to the second reinforcing rods 33 located on the upper side of the second reel bracket 3. The cam assembly 4 is fixedly connected to the second reinforcing rods 33 located on the upper end of the rotating seat 6 by bolts. The first reinforcing rods 32 and the second reinforcing rods 33 are used to strengthen the overall structural strength of the cable storage assembly, and the inner locking blocks 52 enhance the stability of the safety buckle 5 when inserted into the stop slot 341.

[0033] Specifically, the rotating base 6 is symmetrically equipped with two rotating handles 61. By rotating the rotating handles 61, the rotating base 6 and the reel 21 are rotated, allowing for quick retrieval of the cable 211 during on-site wiring. A storage slot 62 is located at the center of the rotating base 6. When laying out the cable 211, the safety clip 5 on the stop slot 341 is removed, and the safety clip 5 is inserted into the storage slot 62 for storage to prevent loss.

[0034] Specifically, the side wall of the housing 1 is provided with a rotating port 11 corresponding to the rotating seat 6 and a locking port 12 corresponding to the safety buckle 5. The rotating port 11 facilitates the rotation of the reel 21 outside the housing to retrieve the cable 211. The locking port 12 facilitates the insertion of the safety buckle 5 into the stop slot 341 when releasing the cable outside the housing. The lower end of the side wall of the housing 1 is provided with a cable outlet 14, and a cable baffle 13 is fixedly connected to the housing 1 at the cable outlet 14. The cable outlet 14 is used for the cable 211 to exit, and the cable baffle 13 can protect the housing 1 from deformation due to the cable 211 being pulled out and squeezed. In addition, a wear-resistant silicone sleeve is provided, which can also serve to protect the cable.

[0035] During use, transportation, and storage, the safety buckle 5 is engaged with the stop groove 341 of the ratchet ring 34 by the symmetrical outer buckle block 51 at the front end, forming a mechanical lock to prevent the cable 211 from rotating due to the spring force of the reel 21.

[0036] Then, during the cable unloading process, the safety buckle 5 is taken out through the locking port 12 on the side wall of the housing 1 and inserted into the storage slot 62 in the center of the rotating seat 6 to prevent loss. Then, the cable 211 is manually pulled, and the cable 211 extends out from the cable outlet 14 at the bottom of the housing. The cable 211 is driven by force to rotate the reel 21. The reel 21 synchronously drives the ratchet ring 34 to rotate. The inner wall of the stop groove 341 of the ratchet ring 34 presses the upper end of the cam 43, causing the cam 43 to compress the spring 44 downward along the slide groove 42. During the rotation, the ratchet ring 34 will apply pressure or release pressure to the cam 43, thereby increasing the damping effect and making the reel 21 easier to pull out. In addition, the inclined surface design of the ratchet ring 34 makes the force more even during cable unloading, effectively reducing the pulling force.

[0037] Then, during the winding process, the two symmetrically arranged rotating handles 61 on the rotating seat 6 are held through the rotating port 11 of the housing 1. The rotating seat 6 is rotated, and the rotating seat 6 drives the reel 21 to rotate synchronously. The cable 211 is gradually wound back onto the surface of the reel 21. During the winding process, the spring 44 always pushes the upper end of the cam 43 to fit against the inner wall of the ratchet ring 34. The mechanical cooperation between the cam 43 and the ratchet ring 34 produces a damping effect to prevent the cable from getting tangled due to excessive winding speed. At the same time, the limiting block 431 at the lower end of the cam 43 prevents the cam 43 from coming off the slide groove 42, ensuring the stability of the winding process.

[0038] Finally, once the cable is wound up or laid down to the required length, remove the safety clip 5 from the storage slot 62 and re-engage its outer clip 51 into the stop slot 341 of the ratchet ring 34 to completely secure the reel 21. At this point, the reel 21 cannot rotate, and the cable 211 remains neatly wound up. Whether during transportation or static storage, this prevents the cable from becoming loose, tangled, or damaged, ensuring signal transmission quality and construction efficiency during subsequent use.
