Description

Technical Field

[0001] This invention belongs to the field of optical cable hub technology, and specifically relates to a protective device for optical cable hubs. Background Technology

[0002] During the construction, maintenance, and storage of optical fiber communication networks, it is often necessary to gather, unwind, and store rolled optical cables. Especially during construction, a sufficient length of cable is often left as a spare. This spare cable is often simply wound into rolls and stored; some are stored using optical cable gathering devices. However, these devices mostly use fixed-structure drums or reels; these devices typically have the following problems:

[0003] Fixed baffle spacing leads to poor adaptability: The baffles on both sides of the drum are usually fixed and not adjustable. When the number of optical cables wound is small and the width occupied is narrow, the fixed baffle spacing is too large, which cannot effectively restrain the optical cables, causing the optical cables to become loose, shift, or even collapse on the drum. However, when a large number of optical cables need to be wound, the fixed baffle spacing may be too small, which limits the winding capacity.

[0004] Cable ends are difficult to secure and easily become tangled: During cable winding or unwinding, especially when operations are paused, there is a lack of effective and convenient ways to secure the ends of the optical cables. They are prone to coming loose from the reel and becoming tangled, which not only affects the cleanliness of the site but may also cause cable wear, tangling, or even tripping hazards. Although some devices may use tape or other temporary securing methods, these are cumbersome to operate and not convenient for frequent winding and unwinding.

[0005] Insufficient protection: Some simple cable management devices lack the necessary protective shell, leaving the coiled optical cable directly exposed to the outside, making it susceptible to damage from dust, moisture, and external impacts.

[0006] Therefore, there is an urgent need for an optical cable hub that can flexibly adapt to different cable winding amounts, effectively fix cable ends, facilitate cable winding and unwinding operations, and provide good protection. Summary of the Invention

[0007] The purpose of this invention is to provide a protective device for optical cable hubs to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a protective device for optical cable hubs, comprising a protective housing, an inlet / outlet port on the protective housing, a collecting roller inside the protective housing, a fixed baffle and a movable baffle respectively at both ends of the collecting roller, a slot on the collecting roller, a plurality of locking tongue slots on the slot, a slider adapted to the slot on the movable baffle, the slider being disposed in the slot, a notch on one side of the slider, a guide post disposed in the notch, a push-pull plate on the guide post, a spring on one side of the push-pull plate, and a locking tongue on the push-pull plate, the locking tongue being adapted to the locking tongue slot.

[0009] Preferably, a protective cover is provided on one side of the protective housing.

[0010] Preferably, a shaft is provided on the protective housing, and the collecting roller is disposed on the shaft.

[0011] Preferably, a circular ring is rotatably mounted on the movable baffle, and a wire ball head is mounted on the circular ring, with a wire hole formed on the wire ball head.

[0012] Preferably, the lead wire ball head has an inlet and outlet opening.

[0013] Preferably, a locking screw is provided on the ball head of the conductor.

[0014] The technical effects and advantages of the present invention are as follows: 1. By setting a movable baffle that can move along the axial direction of the collecting roller, and cooperating with a fixed baffle, the distance between the two baffles can be flexibly adjusted;

[0015] When the number of optical cables wound is small and the width is narrow, the movable baffle can be adjusted inward to reduce the spacing, effectively constrain the optical cable and prevent it from loosening and shifting.

[0016] When a large amount of optical cable needs to be wound and the width is large, the movable baffle can be adjusted outward to increase the spacing and increase the winding capacity.

[0017] It solves the problems of poor adaptability and low space utilization of fixed baffle devices, and realizes "adjustment on demand", which is suitable for different cable volumes and application scenarios.

[0018] 2. The sliding block and T-slot structure is used to ensure smooth movement and accurate guidance of the movable baffle;

[0019] By utilizing the engagement of the locking tongue and the locking tongue groove, combined with the automatic reset force provided by the spring, the movable baffle is automatically and reliably locked after being adjusted to the correct position, preventing accidental displacement during transportation or use.

[0020] During adjustment, simply push the push-pull plate outward to disengage the latch from the latch groove, and the movable baffle can be easily moved. It will automatically lock after being released, making the operation extremely simple and efficient.

[0021] A rotatable ring and a wire ball with a wire hole are set on the movable baffle, providing a dedicated and adjustable fixing and guiding channel for the optical cable outlet, which facilitates cable winding and unwinding;

[0022] The protective shell and protective cover form a semi-enclosed space, providing good physical protection for the optical cable on the collection roller, effectively reducing the intrusion of dust and moisture, as well as damage caused by external impacts and scratches.
