Description

A kind of transformer anti-theft frame

Technical field

The utility model relates to a kind of transformer anti-theft frame, belongs to the transformer anti-theft technical field.

Background technology

At present, it is often stolen to be installed in outdoor transformer, and offender's theft means have following several usually: the bolt around the transformer top cover is turned on, stolen the copper cash in the transformer; Or transformer pulled down from the cross-arm of installing, steal transformer is whole; Or transformer pushed away backwardness from cross-arm, the shell with transformer destroys again, and steals the copper cash in the transformer.Stolen in order to prevent transformer, Chinese patent 200920303185.8 discloses a kind of shackle-type anti-theft device for transformer, connector structure and anti-theft bolt by shackle-type, electric pole and complete the fixing of transformer cover with the carrying transformer, prevent to overthrow, phase shifting transformer, the groove of connector hides the transformer cover bolt, prevent to be opened, high-temperature-resistant layer and the layer of anti-the saw are set in the groove, prevent the violence damage of gas welding, cutting, adopt anti-theft screw to fix between the connector, prevent to be opened by general tool.In use find, the connector of this device adopts welding production, each connector length that making obtains, size are fixed, the transformer and the electric pole that can only be fit to a kind of specification, distance between the size of therefore necessary first measuring transformer and the specification of electric pole and the installation cross-arm electric pole is made the anti-theft device of coupling again, could install at the scene, so just cause long, problem that can't large batch of production of customization time, but also improved production cost.In addition, if measure wrongly, also the problem that anti-theft device can't be installed can appear.Therefore existing anti-theft device for transformer exists complex structure, the scope of application is narrow, installation is inconvenient, anti-theft feature is single, cost of manufacture is than problems such as height.Its result of use still is not ideal enough.

Summary of the invention

The purpose of this utility model is: provide a kind of that can be adapted to the range transformer size and size impact between the cross-arm electric pole is not installed and simple in structure, easy to install and use, theftproof performance better, be suitable for mass production, transformer anti-theft frame that cost of manufacture is lower, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: a kind of transformer anti-theft frame of the present utility model comprises the existing anti-theft bolt of employing, the formation of this transformer anti-theft frame also comprises by horizontal square steel box and vertical square steel box forms taxi font steelframe, the board-like cross-arm of spring steel left side clip hook, right clip hook of the board-like cross-arm of spring steel and double L-shaped spring steel transformer connecting plate, the board-like cross-arm of spring steel left side clip hook and the right clip hook of the board-like cross-arm of spring steel are inserted in respectively in two horizontal square steel boxes up and down of scholar's font steelframe, and board-like cross-arm left side clip hook of spring steel and the right clip hook of the board-like cross-arm of spring steel interconnect by anti-theft bolt, double L-shaped spring steel transformer connecting plate is installed in the vertical square steel box of scholar's font steelframe, and is provided with the anti-theft bolt that is connected with an end of double L-shaped spring steel transformer connecting plate in scholar's font steelframe.

An end of the horizontal square steel box of above-mentioned scholar's font steelframe with and the bottom all be provided with and be used to install and regulate the installing hole that anti-theft bolt is used.

Above-mentioned double L-shaped spring steel transformer connecting plate is bent into L shaped shape respectively and is superimposed together by two steel spring plates to be formed, upper end at double L-shaped spring steel transformer connecting plate is provided with upper junction plate and lower connecting plate, be provided with the connection base in the lower end of double L-shaped spring steel transformer connecting plate, lower connecting plate be connected the base on be provided with the screwed hole that can be connected with anti-theft bolt, on upper junction plate, be provided with the bolt hole that can pass anti-theft bolt.

Owing to adopted technique scheme, adopt two covers transformer anti-theft frame of the present utility model transformer and cross-arm can be locked together, the utility model can prevent effectively that whole transformer is stolen, and can prevent effectively that the top cover of transformer is opened.When needs take off transformer when repairing from cross-arm, have only anti-theft bolt opener anti-theft bolt of the present utility model could be unclamped by special use of the prior art, transformer could be taken off from cross-arm like this.Therefore, the utility model compared with prior art, the utility model not only has the transformer anti-theft of the various sizes of being adapted to and installs, be not subjected to install size impact between the cross-arm electric pole, simple in structure, easy to install, advantage such as theftproof performance is good, cost of manufacture is cheap but also have, and the utility model is particularly suitable for mass production.
