Description
Technical field
The utility model relates to optical cable reel draw off gear, specifically is a kind of backpack optical cable retractable frame.
Background technology
Traditional communication covered wire draw off gear is a kind of spiral shell vehicle frame, constitute by spiral shell car framework and spiral shell hull, but though folding and unfolding communication covered wire, but because the progress of communication carrier, traditional communication covered wire is transmitted the bigger communication cable of capacity and replaces, traditional spiral shell vehicle frame can not satisfy request for utilization, and there is following defective in it: 1. there is fiber cable joint at the communication cable two ends, and traditional spiral shell vehicle frame can't be fixed; 2. traditional spiral shell vehicle frame does not have the brake deceleration device, because speed is uncontrollable, may pull optical cable during the folding and unfolding optical cable; 3. adopt a system, be not easy to the loading and unloading of spiral shell hull.
Summary of the invention
The utility model provides a kind of backpack optical cable retractable frame, its spacious purpose is the defective that overcomes traditional spiral shell vehicle frame, not only can twine folding and unfolding communication covered wire, safely and effectively the fixed light cable joint, can control the rotating speed of spiral shell hull, be convenient to the loading and unloading of spiral shell hull again.
The technical solution of the utility model is as follows: backpack optical cable retractable frame comprises the spiral shell vehicle frame, crank, the spiral shell hull, creel stand, be linked with, end plate in the middle of being provided with in the middle of described spiral shell hull two end plates, form a zonule between middle end plate and right end disc, be shaped on several uniform apertures on the right end disc, utilize the carbine of optical cable head self to hang up in the aperture, optical cable head can be fixed in that the spiral shell hull is loaded on the spiral shell vehicle frame in the optical cable head anchor clamps in the zonule, respectively there is an axle at spiral shell vehicle frame two ends, speed change end axle and dog point axle, axle is connected with the tube end cover key of spiral shell hull, when diaxon inserts fully, key part on the axle combines with spiral shell hull tube end cover internal keyway, and axle can drive the spiral shell hull and rotate; When shaft portion was pulled out, axle key broke away from tube end cover keyway, and the motion of axle and the motion of spiral shell hull are independent of each other; When diaxon was pulled out fully, axle broke away from fully with the spiral shell hull, and the spiral shell hull can take out or pack into; Spiral shell vehicle frame right-hand member is a dog point, and dog point is equipped with brake gear, utilizes the friction of braking mechanism and axle, makes and a spiral shell hull braking deceleration that combines.
Compare with traditional draw off gear, the utlity model has following advantage: 1. owing to a plurality of apertures on end plate in the middle of being provided with and the outer end plate, simple in structure, but it is of many uses, both can guarantee to twine folding and unfolding communication covered wire, but also folding and unfolding ∮ 2 type communication cables 500～2000M, or folding and unfolding ∮ 5 type optical cable 500M; 2. be provided with brake gear, can control folding and unfolding speed, make folding and unfolding speed consistent, so that safe and reliable finish the folding and unfolding operation with the human body leg speed; 3. the spiral shell vehicle frame adopts diaxon system, and resistance is little during cable laying, can effectively brake during take-up, is convenient to the loading and unloading of spiral shell hull simultaneously.
