Embodiment one
Fig. 1 shows the synoptic diagram of the support-type tail fiber device that present embodiment provides, as shown in Figure 1, this support-type tail fiber device comprises a holder chain 1 and fixing respectively two linkers (being designated as 21 and 22 respectively) that hold in the palm chain 1 two ends (being designated as 1a and 1b), all formed the cavity that the left and right side connects in each linker, Fig. 2 shows the right view of linker 21, the side of linker 21 forms the cavity 212 that the left and right side connects, in like manner, the side of linker 22 also forms the cavity 222 that the left and right side connects.One end 1a of holder chain 1 passes the cavity 212 in the linker 21 from the inboard (being the right side of the linker 21 Fig. 1) of linker 21, and curve inwardly from the outside (being the left side of the linker 21 Fig. 1) of linker 21 and be inserted in the linker 21, be fixed on the positioning and guiding parts 211 of the cavity 212 that is arranged in linker 21.The other end 1b of holder chain 1 is inserted into the cavity 222 from the inboard of linker 22, and is fixed in the linker 22.Tail optical fiber 3 is located in the inner space that holder chain 1 forms, and the two ends of tail optical fiber 3 pass respectively from the two ends of holder chain 1 respectively, and is inserted in the flange 213 and 223 that is separately positioned in linker 21 and 22.Among Fig. 1 linker 21 and 22 meet far away, make holder chain 1 can be divided into as shown in fig. 1 straight-line segment on the linear state of top and at the bending section that is in case of bending in linker 21 outsides.In the present embodiment, because the effect of holder chain, when linker direction towards each other relatively moves, the holder chain can only laterally move and can not move up and down, and as shown in Figure 3, in the close mutually process of linker, a part that before had been in straight-line segment will become bending section, and the linearly following straight-line segment of attitude occur in the bottom.In the present embodiment, the structures shape of holder chain can not move up and down and can only laterally move at straight-line segment place holder chain, and certain angle that can only curve inwardly between the chain link of holder chain 1, therefore at bending section, holder chain 1 can form stable structure.
In practice, above-mentioned positioning and guiding parts can be the various parts that gathering sill etc. has the positioning and guiding function.
Describe the concrete structure of the holder chain 1 in the support-type tail fiber device in the present embodiment below in detail.
Fig. 4 shows a kind of schematic perspective view that holds in the palm chain 1 in the present embodiment, and this holder chain 1 is made up of a plurality of chain links that can connect rotatably mutually 10, and adjacent two chain links 10 overlap on width each other.Fig. 5 is the stereographic map of chain link 10 among Fig. 4, and Fig. 6 is the front view of chain link 10 among Fig. 5, and Fig. 7 is the right view of chain link 10 among Fig. 5, and Fig. 8 is the upward view of chain link 10 among Fig. 5.Please be simultaneously referring to Fig. 5 to Fig. 8, chain link 10 has pair of side plates 11, and this lower edge to side plate 11 interconnects by first transverse connection 12.First transverse connection 12 had both served as the link between two side plates 11, can the tail optical fiber that be placed in chain link inside be supported again, in order to avoid be bent downwardly.
Side plate 11 comprises aduncate plate 111 and bandy plate 112, please be simultaneously referring to Fig. 4, when adjacent two chain links 10 overlap, bandy plate 112 on the side plate of previous chain link is positioned at the outside of overlap, aduncate plate 111 on the side plate of the chain link in back is positioned at the inside of overlap, be the inner plate that is arranged on that aduncate plate 111 constitutes adjacent two chain links overlap joint zone, bandy plate 112 constitutes the outside plate that is arranged in adjacent two chain links overlap joint zone.
In practice, overlap joint between adjacent two chain links also rotatably connects and can adopt following specific implementation: at the arranged outside swivel pin 113 of the aduncate plate 111 of the side plate 11 of chain link 10, in bandy plate 112, hinge hole 114 is set, make two adjacent chain links 10 by previous chain link hinge hole 114 and the swivel pin 113 of a back chain link realize hinged, thereby the purpose that reaches overlap joint and be rotatably connected.
In addition, two adjacent chain links 10 can not rotate up each other and can only be rotated down in certain angular range in the holder chain 1 in order to limit, and on the plate that is arranged in the overlap joint intra-zone (is aduncate plate 111 on the side plate at Fig. 5) of chain link 10 the straight line attitude are set and keep stopping surface 111a and crooked attitude restrictions stopping surface 111b.In adjacent two chain links 10, keep stopping surface 111a and crooked attitude restrictions stopping surface 111b contacts with first transverse connection 12 of previous chain link 10 respectively by the straight line attitude of a back chain link 10, these adjacent two chain links 10 can inwardly can only rotate to certain angle so that outwards can only rotate to the straight line attitude.
Describe the effect that the straight line attitude is kept stopping surface and crooked attitude restrictions stopping surface below in conjunction with Fig. 9 in detail to Figure 12.
Fig. 9 and Figure 10 are respectively the schematic perspective view and the front view of two adjacent link (being designated as 10a and 10b respectively) that are in the straight line attitude, as shown in Figures 9 and 10, when chain link 10a and 10b are in the straight line attitude, straight line attitude on the aduncate plate 111 of first transverse connection 12 of the chain link 10b in back is kept stopping surface 111a and is contacted with the upper surface 12a of first transverse connection 12 of previous chain link 10a, because the straight line attitude is kept stopping surface 111a and the upper surface 12a of first transverse connection 12 and is contacted prevention chain link 10a and 10b from the continuation of straight line attitude relative to outwards rotating, so though the chain link in the straight-line segment of holder chain 1 is subjected to downward action of gravity to have the trend of outside continuation rotation in Fig. 1, but still can be stable maintain the straight line attitude, thereby the tail optical fiber of having avoided being placed in the chain link in the straight-line segment arbitrarily is bent downwardly.
Figure 11 and Figure 12 are respectively the schematic perspective view and the front view of two the adjacent chain links (being designated as 10c and 10d) that are in crooked attitude.Shown in Figure 11 and 12, when chain link 10c and 10d are in crooked attitude, crooked attitude restrictions stopping surface 111b on the aduncate plate 111 of the chain link 10d in back contacts with a side 12b towards chain link 10d of first transverse connection 12 of previous chain link 10c, because crooked attitude restrictions stopping surface 111b contacts and will stop chain link 10c and 10d to continue inwardly relative rotation from the angle shown in Figure 11 and Figure 12 with the side 12b of first transverse connection 12, so adjacent two chain links can only be in the straight line attitude to rotation relatively between the angle shown in Figure 11 and Figure 12.Like this, be between the chain link of bending segment among Fig. 1 because the effect of gravity and extruding force, adjacent two chain links will keep the bending state as shown in Figure 11 and Figure 12, make also hold mode stable of holder chain at bending segment place, thereby the tail optical fiber that prevents to be placed in the chain link herein arbitrarily moves.
In addition, Figure 13 shows the schematic perspective view of another kind of holder chain in the present embodiment, is with the different of holder chain shown in Fig. 4, and the upper limb of the side plate of each chain link in the holder chain shown in Figure 13 is each outstanding constraint parts toward each other in the direction.Figure 14 is the schematic perspective view of a chain link in the holder chain among Figure 13, and Figure 15 is the right view of chain link among Figure 14.As Figure 14 and shown in Figure 15, the difference of chain link only is among this chain link and Fig. 5, each outstanding constraint parts 13 toward each other in the direction of two side plates 11 in this chain link 10, and these constraint parts 13 are positioned at the upper limb of side plate 11.After the holder chain that adopts the chain link shown in Figure 14 and Figure 15 to constitute is settled tail optical fiber within it, constraint parts 13 on each chain link can prevent that tail optical fiber from emerging from the top of chain link, and, owing to preferably leave the space between two constraint parts 13 of each chain link, like this when tail optical fiber is installed, can tail optical fiber be filled in wherein from the top of chain link, this is the same with the result who inserts tail optical fiber from the side of chain link, but after chain link had been assembled into the holder chain, tail optical fiber is filled in utilization from the chain link top obviously much smaller than the difficulty that a side from the holder chain wears tail optical fiber.
In addition, Figure 16 shows the schematic perspective view of another kind of holder chain in the present embodiment, and Figure 17 is the schematic perspective view of a chain link in the holder chain among Figure 16, and Figure 18 is the right view of chain link among Figure 17.The difference of the holder chain among this holder chain and Fig. 4 only is that the upper limb of two side plates of each chain link connects by second transverse connection.Particularly, see also Figure 17 and Figure 18, the difference of the chain link among this chain link and Fig. 5 only is, between two side plate 11 upper limbs of chain link 10, second transverse connection 14 is set, because second transverse connection 14 is set, make the steadiness of chain link 10 increase, and second transverse connection 14 can also serve as the effect of crimp, the tail optical fiber that restriction is placed in chain link inside is emerged from the top of chain link.
