Description
The utility model relates to antitheft special bolt on a kind of transformer.
It is to adopt conventional regular polygon hook bolt to install that the fastening foot of transformer and lid connect.Be located in the outlying power equipment transformer in oil field, often with conventional instrument transformer unloaded and steal, or lid is dismantled, steal the copper cash of the inside, produce for country and do great damage by some lawless persons.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and provides one to help antitheft non-standard special bolt and fix, assemble transformer, can play positive role on antitheft.
The purpose of this utility model can reach by the following technical programs: the bolt head of stationary transformer and assembling lid is a socket cap 2, polygonal hole 1 is arranged in the socket cap, and be with protecting cover 3 on cylinder; Bolt passes fastening foot or lid 6 and convex pad cap 8 on the transformer, and threaded end is with cylindrical shape nut 10 on the bolt, and polygonal hole 11 is arranged in the cap head, and is with protecting cover 9 on the cap; Wherein on the protecting cover (3,9) installation ring body (sheet) 12 is arranged.
Can be with convex pad cap 4 on the above-mentioned bolt, convex pad cap is put on circle bolt 2 and the protective hat 3 between the annular solid 12; Polygonal hole (1,11) can be non-regular polygon hole; Outage (5,7) is arranged on the protecting cover (3,9).
The utility model has following effect compared to existing technology: because the fixing and lid of transformer adopts the Bolt Connection of non-standard and structure, no special tool can unload does not any more open, and helps antitheft.
Accompanying drawing is the utility model complete section structural drawing.
Below in conjunction with accompanying drawing will the utility model is described in further detail: shown in figure, the bolt head that adopts is a socket cap 2 in transformer fastening foot and lid 6 connections, polygonal mounting hole 1 is arranged in the socket cap, and be with protecting cover 3 on cylinder; Bolt shank passes fastening foot or lid 6 and convex pad cap 8 on the transformer, and threaded end is with cylindrical shape nut 10 on the bolt shank, and polygonal mounting hole 11 is also arranged in the cap head, and also is with protecting cover 9 on the cap 10; Wherein on the protecting cover (3,9) installing ring body (sheet) 12 is arranged.
Can be with convex pad cap 4 again on the above-mentioned bolt shank, convex pad cap is put on cylinder 2 and the protecting cover 3 between the ring segment 12, and cap 4 is pressed on ring segment and the lid (or fastening foot) 6, and cylinder 2 is pressed on the cap 4 with anchor ring; Polygonal hole (1,11) can be non-regular polygon hole, is furnished with special tool and installs; Outage (5,7) is arranged on the protecting cover (3,9), when raining to discharge.
During use, bolt shank is cover convex-shaped pad cap 4, protecting cover 3 earlier, passes lid connected body 6, puts protecting cover 9, convex pad cap 8 and the cylindrical shape nut 10 of screwing on, and tightens with special tool.
