Abstract
The utility model relates to accessories of electric power equipment, in particular to an anticorrosion locking pin. The anticorrosion locking pin comprises a base consisting of a pin head and a pin body, and the outer surface of the base is coated with a protective layer. The base is made of general cheap metal materials, so that the locking pin is low in cost and environment-friendly. According to test, derusting capacity of the locking pin is over 600 hours and is four times of that of locking pins on the same conditions by aid of the anticorrosion protective film.
Description
Technical field
The utility model relates to a kind of electric power equipment accessory, especially a kind of spring bolt, a kind of specifically corrosion resistant spring bolt.
Background technique
At present, the national grid center is institute's electrification gold utensil accessory one spring bolt in engineering construction, for guaranteeing non-corrosive under moist and the weak acid alkali environment in the open air, NBS (DL/T764.2-2001, GB4056-83) material of Yao Qiuing is 0Gr18Ni9 (304), along with the world, the constantly soaring and rise of domestic steel market price, some supporting enterprises are in order to reduce cost, employed material is the Ferritic Stainless Steel that does not contain the Ni element, but this kind material antirust ability extreme difference, build engineering more in use for the national grid center and bring very big loss, supporting enterprise is complained, also accepts the punishment of great number.In addition, current standard requires to use the spring bolt of material 06r18Ni9 (304), antirust ability also has narrow limitation, method check by standard GB/T10125-1997 " artificial atmosphere corrosion test-salt spray test ", with the spring bolt that stainless steel 0Gr18Ni9 (304) makes, antirust ability at most just reaches 200 hours.Be badly in need of the spring bolt that a kind of cost is low, rotproofness is strong for this reason.
Summary of the invention
The purpose of this utility model is that the spring bolt that a kind of cost is low, rotproofness is strong will be provided.
The purpose of this utility model is achieved in that
The corrosion resistant spring bolt comprises the matrix that pin head, shank constitute, and the described outer surface of matrix that is made of pin head and shank scribbles layer protecting film.
Owing to adopt said structure, this spring bolt had the following advantages:
A. the common cheap metallic material of matrix adopting, the low and environmental protection of cost;
B. use the corrosion resistant protective film, check under the same conditions, antirust ability reached more than 600 hours, and antirust ability provides 3 times.

Fig. 3 is first kind of embodiment's overall structure of the utility model schematic representation.
Embodiment
The corrosion resistant spring bolt comprises the matrix that pin head 1, shank 2 constitute, and the described outer surface of matrix that is made of pin head 1 and shank 2 scribbles layer protecting film 3.
The common cheap metallic material of superpower corrosion resistant closed pin matrix adopting, outer surface is coated with one deck antirust protective film 3, protective film 3 strong adhesions.Matrix is a Common Straight Carbon Steel; Protective film 3 has three kinds: electrophoresis protective film, coating protection film, injection moulding protective film; The color of protective film 3: shades of colours such as black, white, Huang, indigo plant;
Though the application's title life is " corrosion resistant spring bolt ", because of the region difference, this product also is called as " closed pin " or " cotter pin ".
Claims (1)
1. a corrosion resistant spring bolt comprises the matrix that pin head, shank constitute, and it is characterized in that: the described outer surface of matrix that is made of pin head and shank scribbles layer protecting film.
