Description

Technical Field

[0001] The utility model relates to the technical field of communication optical cable unwinding devices which are convenient for tension adjustment, in particular to a communication optical cable unwinding device which is convenient for tension adjustment. Background Art

[0002] Communication optical cable is composed of a cable core and an outer sheath consisting of several optical fibers (usually from a few to several thousand). Compared with traditional symmetrical copper loops and coaxial copper loops, optical fiber has much larger transmission capacity, less attenuation, longer transmission distance, smaller size, lighter weight, no electromagnetic interference, and lower cost. It is currently the most promising communication transmission medium. It is widely used in signal transmission in various departments such as telecommunications, electricity, and broadcasting, and will gradually become the main body of future communication networks. The main difference between optical cables and electrical cables in structure is that optical cables must have reinforcing components to withstand external mechanical loads to protect optical fibers from various external mechanical forces.

[0003] A communication optical cable unwinding device that is easy to adjust the tension is disclosed in the Chinese utility model patent application disclosure CN215326075U. Although it solves the problem of the optical cable being entangled, the communication optical cable unwinding device that is easy to adjust the tension still has the following disadvantages: First, although the above-mentioned communication optical cable unwinding device that is easy to adjust the tension adjusts the rotation speed of the optical cable drum by pressing the rotating shaft to achieve tension adjustment, it cannot directly press the optical cable line when adjusting, so that the surface part of the optical cable is still too loose; Second, when the above-mentioned communication optical cable unwinding device that is easy to adjust the tension adjusts the rotating shaft, it is necessary to tighten the bolts for adjustment, and this adjustment method requires the preparation of tools in advance and is relatively time-consuming and wastes manpower. In addition, it is a single-sided compression of the rotating shaft. After long-term compression, it is easy to cause wear at the intersection of the rotating shaft and the fixed plate.
