Description

Technical Field

[0001] The utility model relates to the technical field related to optical fiber wiring, in particular to an optical fiber for detecting a line without plugging or unplugging. Background Art

[0002] In actual work, when the optical fiber is rolled up randomly or loose, different optical fibers will be entangled. This requires workers to find the ports at both ends of the optical fiber in the messy optical fiber when using it. Due to too many optical fiber cables, it is impossible to sort out the positions of the two ends of the line. The existing terminal sorting method still uses the means of plugging and unplugging the ports, connecting the two ports of the optical fiber to the equipment respectively, and finding the two ports of the optical fiber by the success or failure of data transmission. Obviously, this search method requires continuous plugging and unplugging of the optical fiber ports, which will cause the workers to waste a lot of time and manpower and cause great inconvenience. For this reason, we propose an optical fiber for detecting lines that does not require plugging and unplugging. Utility Model Content

[0025] Example 1, please refer to Figure 1 - Figure 7 The utility model provides a technical solution: an optical fiber for a detection line that does not require plugging and unplugging, including an optical fiber body 1, the optical fiber body 1 includes a lighting tube 12 fixedly connected to the periphery on both sides thereof, an outer shell 11 is fixedly installed at both ends of the optical fiber body 1, the lighting tube 12 is arranged on the inner side of the outer shell 11, and a tail sleeve 13 is fixedly installed on the inner end face of the outer shell 11 and is sleeved on the periphery of the optical fiber body 1 and the lighting tube 12, a connecting seat 2 is plugged and installed on the outer end face of the tail sleeve 13, a rotating plate 21 is rotatably installed on the outer end face of the connecting seat 2, a through cavity 22 matching the lighting tube 12 is opened in the middle of the connecting seat 2 and the rotating plate 21, a plurality of sealing plates 23 that fit each other are slidably installed between the connecting seat 2 and the rotating plate 21, and the plurality of sealing plates 23 match the lighting tube 12.

[0026] Working principle: During the cable arrangement process, when it is necessary to find the other end of the optical fiber body 1, align the external lighting device with the lighting tube 12 on one side. Through the refraction effect of the lighting tube 12 and the inside of the optical fiber body 1, the light can be emitted from the other lighting tube 12, so that the other end of the optical fiber body 1 can be found, thereby improving the cable arrangement efficiency;

[0027] Through the sliding cooperation between the connecting seat 2 and the rotating plate 21 and multiple sealing plates 23, the rotating rotating plate 21 can drive each sealing plate 23 to shrink inward or expand outward, so that the outer end of the lighting tube 12 can be sealed to prevent the lighting tube 12 from contacting with external dust and other impurities, thereby achieving the effect of protecting the lighting tube 12 and the optical fiber body 1.

[0028] Embodiment 2, the upper and lower ends of the plurality of sealing plates 23 are respectively fixedly mounted with a sliding shaft 26 and a limiting slider 24, the upper end surface of the connecting seat 2 is provided with a plurality of limiting slide grooves 25 respectively slidingly matched with each limiting slider 24, the lower end surface of the rotating plate 21 is provided with a plurality of arcuate slide grooves 27 respectively slidingly matched with each sliding shaft 26, the sliding shaft 26 is cylindrically arranged, the arcuate slide grooves 27 are inclinedly arranged, an annular rotating cavity 3 is provided in the connecting seat 2, a connecting block 31 is fixedly mounted in the annular rotating cavity 3, and the outer surface of the rotating plate 21 is provided with a plurality of arcuate slide grooves 27 respectively slidingly matched with each sliding shaft 26. A sliding block 32 that slides with the annular rotating chamber 3 is fixedly installed around it, a first spring 34 and an arc-shaped telescopic sleeve 33 that are plugged into each other are fixedly installed between the connecting block 31 and the sliding block 32, the first spring 34 is sleeved on the periphery of the arc-shaped telescopic sleeve 33, a first telescopic sleeve 4 is fixedly installed on the periphery of the tail sleeve 13, a second telescopic sleeve 41 that is plugged into and fits with the first telescopic sleeve 4 is fixedly installed on the lower end surface of the connecting seat 2, and a threaded sleeve 42 that threadably fits with the second telescopic sleeve 41 is rotatably installed on the periphery of the tail sleeve 13.

[0029] When the optical fiber body 1 is being arranged, the threaded sleeve 42 is rotated on the periphery of the first telescopic sleeve 4. The first telescopic sleeve 4 is plugged in with the second telescopic sleeve 41 to restrict the movement direction of the second telescopic sleeve 41, so that the rotating threaded sleeve 42 can drive the connecting seat 2 to move downward through the threaded cooperation between the first telescopic sleeve 42 and the second telescopic sleeve 41.

[0030] When the connecting seat 2 moves downward, its internal sealing plate 23 will be plugged into and contacted with the upper end of the lighting tube 12. Through the contact effect between the two, each sealing plate 23 will be driven to expand outward, so that the upper end of the lighting tube 12 is exposed, thereby aligning the external lighting equipment with the upper end of the lighting tube 12 on one side, and also facilitating the staff to check the output light from the lighting tube 12 on the other side.

[0031] Among them, during the outward expansion movement of the sealing plate 23, the sliding cooperation between the limit slider 24 and the limit slide groove 25 and between the cylindrical slide shaft 26 and the inclined arc slide groove 27 drives the rotating plate 21 to rotate, thereby achieving the effect of compressing the first spring 34; thereby, when the threaded sleeve 42 is rotated in the reverse direction, the connecting seat 2 is driven to move upward, and when the sealing plate 23 and the polishing tube 12 are separated from each other, the first spring 34 restores the deformation effect, which can drive the rotating plate 21 to rotate in the reverse direction, and drive each sealing plate 23 to shrink inward, so as to achieve the effect of sealing the upper end of the polishing tube 12.

[0032] In embodiment 3, the optical fiber body 1 comprises an optical fiber protective layer 101 , an aramid yarn layer 102 , a cladding 103 , and a fiber core 104 . The cladding 103 , the aramid yarn layer 102 , and the optical fiber protective layer 101 are sequentially fixedly installed on the periphery of the fiber core 104 .

[0033] The cladding 103 , the aramid yarn layer 102 and the optical fiber protection layer 101 are sequentially arranged on the periphery of the optical fiber core 104 , so as to achieve the effect of protecting the optical fiber core 104 .

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
