Description

Technical Field

[0001] The utility model relates to the technical field of optical cable laying, and particularly relates to a self-locking optical cable hook. Background Art

[0002] As the main medium for transmitting data, optical cables need to follow specific installation design and construction standards. Aerial optical cables are optical cables used by hanging on utility poles. This laying method can utilize the original aerial open wire pole lines, and has advantages such as saving construction costs and shortening the construction period, and is an important laying method. Aerial optical cables are mainly applied to areas with unstable geology, where direct burial is not possible in urban areas and there is no telecommunication pipeline, special mountainous and water network conditions, and areas where pole lines can be utilized.

[0003] There are mainly two hanging methods for aerial optical cables, namely the messenger wire type and the self-supporting type. Currently, the messenger wire type laying method is mostly adopted. Specifically, the messenger wire is first fastened to the utility pole, and then the optical cable is suspended on the messenger wire with a hook. The load of the optical cable is borne by the messenger wire. The messenger wire type hanging method can effectively protect the optical cable from external physical damage and can reduce the interference with the optical cable transmission signal.

[0004] In actual construction, within the specified suspension weight range of the messenger wire, two or more optical cables are hung in one hook. When hanging multiple optical cables with different cable diameters, the cables in the hook are often stacked and hung in stages, and cannot occupy a relatively fixed cable position in the hook, so that the cables are stacked and wound together, and it is impossible to visually and quickly distinguish the cable types. In addition to being time-consuming and increasing the construction difficulty, misidentification (of cable types) often occurs during fault repair and maintenance. Moreover, with the alternation of winter and summer seasons, the optical cable expands and contracts thermally, the winding of the optical cable increases friction, and mutual tension is generated between the cables, which is likely to damage the line and affect communication security. Therefore, there are still drawbacks and deficiencies in the prior art. Summary of the Utility Model

[0032] Among them, the engaging portion 123 is engaged with the holding portion 132, and when the locking member 13 is rotated, the locking member 13 can be separated from the locking ring 12, thereby unlocking.

[0033] Please refer to Figures 1 to 3 simultaneously. The locking ring 12 includes a first buckle ring 121 and a second buckle ring 122. The first buckle ring 121 and the second buckle ring 122 are in an arc structure. One end of the first buckle ring 121 is fixedly connected to the connecting portion 11, and the end of the first buckle ring 121 away from the connecting portion 11 is hinged to the second buckle ring 122, so that the second buckle ring 122 can rotate along the hinge axis of the second buckle ring 122 and the first buckle ring 121.

[0034] Since the suspension wire and the optical cable are cylindrical, and the first buckle ring 121 and the second buckle ring 122 are arranged in an arc structure, the first buckle ring 121 and the second buckle ring 122 can be fully attached to the suspension wire and the optical cable, so that the suspension wire and the optical cable can be reliably fixed by the locking ring 12.

[0035] The engaging portion 123 is provided at the end of the second buckle ring 122 facing away from the first buckle ring 121. The engaging portion 123 is fixedly connected to the second buckle ring 122.
