Description

Technical Field

[0001] The utility model relates to the technical field of self-supporting cables, in particular to an 8-shaped self-supporting overhead data cable. Background Art

[0002] Data cables are also called optical cables. Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. They are communication cable components that use one or more optical fibers placed in a sheath as transmission media and can be used individually or in groups. Optical cables are mainly composed of optical fibers (glass fibers as thin as hair) and plastic protective sleeves and plastic sheaths. There is no gold, silver, copper, aluminum or other metals in the optical cable, and it is generally worthless to recycle.

[0003] At present, when the traditional data cable is suspended overhead, the staff first erects the bracket along the data cable. After the bracket is erected, a steel strand is fixed on the bracket. After the steel strand is fixed, the data cable is laid. After the data cable is laid, the staff will hang the data cable on one end of the hook and hang the other end on the steel strand, thereby completing the erection of the data cable.

[0004] Because, when laying the data cable, it is necessary to first fix a steel strand on the bracket, and then use a hook to hang the data cable on the steel strand. This laying method not only increases the labor of the staff and reduces the laying efficiency, but also, because the hook is used to hang it on the steel strand, it is easy for the unsuspended part to be deformed and bent under the action of gravity, thereby affecting the subsequent communication.

[0040] The working principle and use process of this utility model:

[0041] In use:

[0042] When in use, first, install the wall piece 1. During installation, stick the wall piece 1 to the place closest to the required overhead position. At this time, fix the wall piece 1 to the wall or the top of the wall by nails. If it is fixed on the wall, after fixing, at this time, according to the overhead position, the position of the first rectangular rod 42 in the first rectangular sleeve 45 can be adjusted. During adjustment, first, loosen the first nut 45, and then remove the first bolt 44. After removal, at this time, the position of the first rectangular rod 42 in the first rectangular sleeve 45 can be adjusted. After adjustment, at this time, insert the first bolt 44 into the corresponding adjustment hole 443, and the adjustment of the first adjustment rod position can be completed. After adjustment, at this time, adjust the position of the suspension assembly 6 according to the overhead height, and when adjusting the second telescopic assembly 5, the adjustment method is the same as the first telescopic assembly 4. After adjustment, at this time, start to overhead the cable assembly 2. Before overheading, first, position the first arc frame 73 and the second arc frame 76 respectively. When the locking screw 78 is tightened, the locking screw 78 drives the second arc clamp 76 to move toward the first arc clamp 73, thereby clamping the first protective cover 21 through the cooperation of the second arc clamp 76 and the first arc clamp 73. After clamping, the staff begins to hang the hanging hook 72 in the rectangular frame 61. Before hanging, the L-shaped resistance rod 62 is moved first, and the L-shaped resistance rod 62 will drive the damping rod 63 to move. When the L-shaped resistance rod 62 moves to the specified position, the hanging hook 72 is started to be hung on the rectangular frame 61, and then the L-shaped resistance rod 62 is released. At this time, the L-shaped resistance rod 62 will fix the hanging hook 72 under the action of the damping rod 63 to prevent the hanging hook 72 from detaching from the rectangular frame 61. At the same time, the cable component 24 is suspended by the steel strand 22 in the first protective cover 21 without affecting the communication of the optical fiber 246 in the cable component 24.
