Description
Technical field
The utility model belongs to the machanical fastener technical field, especially relates to a kind of fastening piece with transformer anti-theft function.
Background technique
Along with the development of China's electric utility, electrical network extends in all direction, and transformer spreads all over the place, and has satisfied people's work and living needs.But a large amount of outdoor transformers are remote owing to being located in, and difficult management gives social lawless person with opportunity.They steal, damage transformer without restraint, have brought massive losses and inconvenience for power department, industrial and agricultural production, national defense construction and people's life.According to the statistics made by the departments concerned, up to ten thousand in the transformer of the annual stolen loss of loosing core, numeral is startling, and direct loss that cause thus and indirect loss are heavy.The fastening piece on common transformer case edge is to make the connection fastening piece with screw bolt and nut, and general purpose tool is promptly removable, goes up the obstinate lawless person of only a few for society and is engaged in the theft destructive activity with opportunity.Guarantee transformer release lawless person's destruction, guarantee that the operation of electrical network long-term safety is very important something.So a kind of transformer fastening piece with anti-theft feature of necessary invention, to prevent dismounting to the non-original idea of transformer.
The model utility content
The purpose of the utility model is the stolen problem of transformer to power circuit, and a kind of transformer fastening piece with anti-theft feature of reliable performance is provided.
For realizing above-mentioned purpose, the utility model has adopted following technological scheme to be: a kind of transformer anti-theft fastening piece, comprise screw bolt and nut, and it is characterized in that: also comprise stealingproof sleeve; Stealingproof sleeve is columnar structured, and it is the through hole of band bottom surface, and the screw thread of bolt is provided with vertical elongated slot; Bolt passes the bottom surface of stealingproof sleeve, and the stealingproof sleeve inwall is provided with in the elongated slot that protruding nail is fastened on bolt, guarantees that bolt can not rotate; It is columnar structured that nut is similarly, and nut can be inserted in the stealingproof sleeve, is provided with step in the nut; The upper and lower is respectively equipped with internal thread, and the lower internal thread and the bolt of nut are suitable, and the upper end annular portion of nut is provided with notch.The protruding nail of stealingproof sleeve inwall can be a pin, and pin on the antitheft jacket wall, also can be on the screw precession stealingproof sleeve wall through pin, and its main purpose is to guarantee that bolt can not rotate.
In the time of use, the case that bolt passes transformer along the hole, case lid hole and stealingproof sleeve, the bottom surface of stealingproof sleeve is pressed on the case lid, nut the end that is screwed into bolt, just can be realized anti-theft feature through special tool.Usually its special tool comprises screw rod and the sleeve suitable with the nut upper internal threaded, and the profile of sleeve is identical with nut, and the sleeve lower end combines with the upper end notch negative and positive of nut, and sleeve can drive nut and rotate with fastening nut.During use, screw rod passes in the sleeve, is screwed into the nut upper internal threaded, after tightening, and tightly is attached to the bottom of screw rod on the step surface in the nut, realizes screw rod and nut check, cooperates the sleeve nut of just can back-outing with sleeve.The transformer anti-theft fastening piece of this structure must just can be opened by the special-purpose anti-theft tool of adapted, has improved the theftproof performance of transformer widely.
During concrete the use, the head of bolt is the round end cap.So just prevent that the head that adopts instruments such as spanner to be screwed in bolt from opening.
During concrete the use, envelope is provided with friction tight circular end cap in the stealingproof sleeve upper end.The anti-on the one hand sealing of circular end cap leaves in the stealingproof sleeve, gets rusty preventing, has increased anti-theft feature in addition.
During concrete the use, circular end cap center is provided with screw, and screw is provided with screw.Owing in the circular end cap drive fit stealingproof sleeve upper end, be provided with screw, in the time of can making things convenient for normal uses, need open the transformer anti-theft fastening piece, go out the round nose caping with another special tool entering screw.
With the plain bolt of the present usefulness of transformer and the fastening piece of nut structure, be replaced as the transformer anti-theft fastening piece of the utility model, with special tool that bolt and anti-theft nut is fastening then, thus reach the whole stolen purpose of transformer.During concrete the use, according to the size of transformer, can adopt two perhaps transformer anti-theft fastening pieces of several the utility model, other the fastening piece with plain bolt and nut structure is realized the purpose of guarding against theft too.Functions such as this device has pick-proof, anti-pounds, anti-saw are sealed with stealingproof sleeve, and non-special tool can't installing/dismounting, is the desirable whole anti-theft product of transformer.
The beneficial effect of the utility model is: the utility model is simple in structure, and is easy to operate, safe and reliable, can effectively avoid transformer stolen, ensures industrial and agricultural production, brings convenience the economic benefit obvious social benefit to daily life.
