Distribution transformer theft-proof bolt and special disassembly tool

Abstract

The invention discloses a distribution transformer theft-proof bolt and a special disassembly tool, which comprise a theft-proof bolt and a disassembly tool. According to the invention, the conventional hexagonal nut is changed into an annular nut, two groups of inclined concave surface slots are oppositely arranged on the side annular surface of the annular nut, a plurality of inclined concave surface slots of the two groups of inclined concave surface slots are crossed, one group of inclined concave surface slots are arranged clockwise, and the other group of inclined concave surface slots are arranged anticlockwise, so the annular nut provided with the inclined concave surface slots can not be disassembled through a common tool. The disassembly tool is provided with only one group of inclined concave surface slots, and the shapes and the distribution of the inclined concave surface slots are matched with the shapes and the distribution of the inclined concave surface slots on the annular nut. Under the condition of forward rotation, the nut is compressed; and under the condition of reverse rotation, the nut is loosened, and the effect of assembling and disassembling the nut is just achieved. The specially made bolt is combined with the special disassembly tool to achieve a good theft-proof effect, so criminals can not steal the bolt, and the bolt and the special disassembly tool have simple structures and are convenient to use.

Description

[0001] technical field [0002] The invention belongs to the technical field of anti-theft appliances, in particular to a distribution transformer anti-theft bolt and a special disassembly tool. Background technique [0003] The transformer is one of the important equipment in the power distribution network, but the incident of the transformer being stolen often occurs. After criminals steal the transformer, the area served by the transformer will have a power outage, which has brought a huge impact on production and life. Today's transformers are generally fixed by bolts, so thieves can easily use disassembly tools to remove the bolts, thereby stealing the transformers. The anti-theft technology of transformers needs to be improved more and more. Contents of the invention [0004] The invention provides a distribution transformer anti-theft bolt and a special disassembly tool with good anti-theft effect, convenient use and careful design. [0005] The technical so...
