Description

Technical Field

[0001] The invention relates to the technical field of optical cable clamping equipment, in particular to a pressure-resistant insulated steel strand-free optical cable fixing hardware. Background Art

[0002] Optical cable is a communication cable assembly used for optical signal transmission. It is mainly composed of optical fiber (glass filaments as thin as hair) and plastic protective sleeve and plastic sheath. Optical cable can meet optical, mechanical or environmental performance specifications and has multiple uses and classification methods.

[0003] Traditional optical cable installation and positioning mostly use threaded adapters and snap-on locking. After working in complex environments for a long time, it is not only difficult to perform maintenance, but the adapter-type snaps have a small scope of application. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a pressure-resistant insulated steel strand-free optical cable fixing hardware, which solves the problems of threaded adaptation and snap-on locking, which are not only difficult to repair after working in a complex environment for a long time, but also have a small scope of application of the adaptive snap-on.

[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a pressure-resistant insulated steel strand-free optical cable fixing hardware, including a fixing frame, a connecting rod and an outer limit ring, the bottom of the fixing frame is fixedly connected to two connecting rods, the top of the outer limit ring is fixedly connected to one end of the two connecting rods away from the fixing frame, the inner side wall of the outer limit ring is slidably connected to two inner limit rings, the inner side walls of the two inner limit rings are each provided with a plurality of locking structures, and the plurality of locking structures each include a locking spring, one end of the locking spring is fixedly connected to the inner side wall of the inner limit ring, and the other end of the locking spring is fixedly connected to a locking arc plate, and the shape of the locking arc plate is an arc.

[0006] Preferably, the locking arc plate is rotatably connected to a side wall away from the locking spring with a plurality of adjusting balls.

[0007] Preferably, two groups of T-shaped connecting blocks are fixedly connected to the outer side wall of the inner limit ring.

[0008] Preferably, the inner side wall of the outer limiting ring is provided with a connecting slideway corresponding to the T-shaped connecting block.

[0009] Working principle: When in use, place the optical cable that needs to be positioned inside the inner limit ring. Since the inner wall of the outer limit ring is provided with a connecting slide corresponding to the T-shaped connecting block, the two inner limit rings are rotated at this time to limit the position of the optical cable from the bottom, that is, to wrap the optical cable, thereby realizing portable fixation of optical cables of different sizes, and the limiting method of this fixing hardware is also very convenient in subsequent maintenance operations. After the optical cable is locked and limited, the cooperation of the locking spring and the locking arc plate can stably limit the position of the optical cable, ensuring that it is in a stable state during subsequent work. The presence of the adjustment ball can adapt to the convenient adjustment of the installation angle during the installation process, and in the actual maintenance process, it is also very convenient to rotate the angle of the optical cable, and the period status can be observed without taking it out.

[0010] (III) Beneficial effects The present invention provides a pressure-resistant insulated steel strand-free optical cable fixing hardware. It has the following beneficial effects: 1. The pressure-resistant insulated steel strand-free optical cable fixing hardware has a connecting slideway corresponding to the T-shaped connecting block on the inner wall of the outer limit ring. At this time, the two inner limit rings are rotated to limit the position of the optical cable from the bottom, that is, the optical cable is wrapped, thereby realizing portable fixation of optical cables of different sizes, and the limiting method of this fixing hardware is also very convenient in subsequent maintenance operations.

[0011] 2. After the optical cable is locked and limited, the locking spring and the locking arc plate can cooperate to limit the position of the optical cable stably, ensuring that it is in a stable state during subsequent work. The existence of the adjustment ball can adapt to the convenient adjustment of the installation angle during the installation process, and in the actual maintenance process, it is also very convenient to rotate the angle of the optical cable, and the status can be observed without taking it out.
