The adjustable internal diameter surrounded；Pointer mounting hole is set at radius of curvature adjustable plate outer edge, is equipped on pointer mounting hole
It can be along the pointer that finger slips track moves.
It is respectively arranged on the radius of curvature adjustable plate and expansion rail and adjusts the fixed bracket of bolt, among fixed bracket
It is formed with threaded hole, will adjust in bolt insertion threaded hole and bolt is adjusted by rotation and realize adjustment internal diameter function.
The pointer includes that pointer main body and pointer main body colouring pointer screw hole, pointer screw hole are penetrated through finger slips track
In pointer mounting hole, and fixed by screw in inside.
The sheet metal edge is arc-shaped.
The advantages and positive effects of the utility model are as follows:
1, annulus is made using elastic metallic material in the utility model, and radius may be set to be examined required by optical cable
Radius of curvature provides relatively accurate reliable template, when measuring optical cable radius of curvature in substation, operation side for on-the-spot test
Method is simple, and adjustment speed is fast, is suitable for the complex environment that live optical cable model is more, quantity is big, can high degree promotion scene survey
The working efficiency of examination, inspection result is accurately objective, application easy to spread.
2, the utility model is to the same model optical cable in substation, it is only necessary to which auxiliary testing tool is disposably adjusted to institute
Need size, can be rapidly completed live optical cable static buckling radius whether He Ge test job, test result is accurately objective,
High degree improves working efficiency.
3, the utility model is compact-sized, size is small, light-weight and easy to carry.

Specific embodiment
The utility model is further described below in conjunction with attached drawing.
A kind of auxiliary tool for optical cable static state radius of curvature in rapid verification substation, such as Fig. 1 a, Fig. 1 b and Fig. 1 c
It is shown, including flexible sheet metal, sheet metal side are radius of curvature adjustable plate 1, the sheet metal other side is to stretch
Contracting track 4 is equipped with graduation indication plate 2 on the corresponding outer wall of expansion rail 4, finger slips rail is carved in the middle part of graduation indication plate
Road 5.When in use, radius of curvature adjustable plate 1 is inserted into expansion rail 4, it is ensured that radius of curvature adjustable plate 1 is close to sheet metal
Outer wall, main body frame remain round, as shown in Figure 2.It is respectively set on radius of curvature adjustable plate and expansion rail
Have and adjust the fixed bracket 6 of bolt, be formed with threaded hole among the fixation bracket, bolt 9 will be adjusted and be inserted into threaded hole and by turning
It is dynamic to adjust bolt, it can precision regulator internal diameter.
