Specific embodiment
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described
Embodiment is only a part of embodiment of the present utility model, rather than the embodiment of whole.Based on the enforcement in this utility model
Example, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made are belonged to
The scope of this utility model protection.
As illustrated in fig. 1 and 2, this utility model embodiment includes：
A kind of extra large cable bend limiting device, including welding connector 2 and limiter 1, described 2 tail end of welding connector are arranged
There is flange arrangement, described limiter 1 is connected on the flange arrangement of welding connector 2, described welding connector 2 and limiter 1
Inside be equipped with cable through-hole 3 and by centrage dimidiation symmetrical structure, multiple limiters 1 carry out series connection socket connection
Together, draw-in groove 11 is provided with the front end of described limiter 1, the tail end of limiter 1 is provided with flange 12, described limiter
1 series connection socket is to be stuck in the Hafu-type structure formed in draw-in groove 11 by flange 12, between described flange 12 and draw-in groove 11
There is certain interval, described limiter 1 is further opened with monitoring optical cable through hole in the centrage same horizontal line of cable through-hole 3
13, the described centrage decentraction for monitoring optical cable through hole 13 and cable through-hole 3.
In above-mentioned, the quantity of described limiter 1 is at least 2 sections.This utility model is can be according to different demands series connection one
The limiter 1 of fixed joint number, is saved per two and is connected together by Hafu-type structure interval between limiters 1, described flange 12
There is certain interval and draw-in groove 11 between, to ensure the bending of certain angle is not formed between two section limiters 1, after so connecting
Entirety can be bent in certain bending radius, adjustable according to different requirement series connection joint numbers and bending radius.
Cable through-hole is provided with inside the device, each unit section is divided into two by centrage, and installation is to be socketed successively
