Abstract
The present invention relates to a bolt case and, more particularly, to a bolt case and a sacrificial device capable of preventing a corrosion of a bolt in an event of exposure to calcium chloride used as winter snow removing agent by attaching the sacrificial device to the bolt and covering the case. According to the present invention, by attaching zinc having a higher ionization tendency than iron in which iron of the bolt is ionized by water and the snow removing agent to cause corrosion, zinc is corroded instead of iron to form an oxide film on the iron. In addition, by using a case made of stainless steel, polyurethane, and polycarbonate, iron of the bolt can be prevented from being exposed to water or snow removing agent such that a problem of corrosion of iron can be solved.
Description
In general, the existing bolts have corrosion surfaces more easily because they are made of iron.
The present invention relates to a bolt case, and more particularly, to a bolt case which is exposed to calcium chloride used as a snow removing agent for winter and corrodes the bolt of an automobile wheel. The bolt case has a sacrifice device and a case to prevent corrosion of the bolt. To a sacrificial device.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to prevent a bolt from being corroded even when the case is covered with calcium chloride by attaching a sacrificial device to the bolt.
In the present invention, iron of a bolt is ionized by water and a snow remover to cause corrosion, and by attaching zinc having a higher ionization tendency than iron, zinc is corroded instead of iron to form an oxide film on iron, and stainless steel, polyurethane, polycarbonate In this case, it is possible to prevent the corrosion of the steel by preventing the steel of the bolt from being exposed to the water or the snow remover.
As described above, according to the present invention, even when the bolts of winter tires are exposed to the snow remover sprayed on the road, it is possible to prevent damage to the tire of the vehicle owners by protecting the bolts constituted by the iron.
1 is a side view of a corrosion prevention bolt case and a sacrificial device according to the present invention;
The present invention will now be described with reference to the drawings.
1 shows two cases of a bolt and a bolt. The
The case consists of hexagonal bolt-shaped stainless steel, polyurethane, polycarbonate, and the sacrificial device is zinc attached between the bolt and case. The present invention can selectively cover the head portion of a conventional hexagonal bolt, and zinc as a sacrificial device can be detached between the case and the bolt.
