Problems solved by technology

[0004] In the process of erecting the optical cable, the optical cable needs to be retracted and released, so as to facilitate the extraction of the optical cable during the erection process. During the erection of the residential optical cable, it is necessary to manually retract and unwind the optical cable through the manual roll of the optical cable. In this way It is inconvenient to release, and at the same time, it is easy to cause safety hazards; and after the winding is completed, it is always difficult to fix the wire end. If it is not fixed, it is easy to cause loose coils

Abstract

The invention discloses a barrier-free take-up and pay-off device for erecting communication optical cables of outdoor advertising boards. The device comprises stand columns, a take-up mechanism, a control mechanism, a limiting mechanism, a supporting cylinder, a sliding cylinder, an inner gear, a wedge-shaped block, a limiting gear, a first spring, a fixing mechanism, a fixing groove, a stopping block, a pressing block, a second sliding groove and a second spring. The device has the beneficial effects that a reel is conveniently installed and connected through the two stand columns, the reel is conveniently extracted under the action of a handle, take-up and pay-off work can be conveniently carried out in different areas, the reel is rotated under the action of a rotating shaft so that an optical cable can be conveniently wound, and when a sliding rod abuts against the interior of a clamping groove under the action of a compression spring, under the effect of limiting the rotating shaft, the reel cannot rotate, and the wound optical cable is prevented from being discharged randomly; when the optical cable needs to be released, the two sliding rods are separated from the interior of the clamping groove under the action of the compression spring by pulling the sliding rods, so that the reel is convenient to rotate, and the winding work of the optical cable is facilitated through the rotation of the crank.

Description

technical field [0001] The invention relates to a retractable device, in particular to a barrier-free retractable device for erecting communication optical cables of outdoor billboards, belonging to the technical field of outdoor billboards. Background technique [0002] In order to achieve effective promotion of brands or products, in addition to common billboards, most advertisers also choose to put billboards in outdoor environments, such as along highways and so on. However, in order to ensure that the electronic screen of the outdoor billboard can update the relevant display screen and data transmission in real time, it is usually necessary to erect a communication optical cable when establishing an outdoor billboard to ensure its communication effect. [0003] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmiss...
