Therefore, it is necessary to provide a plastic housing with good corrosion resistance to solve the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a plastic shell that corrosion resistance is good possesses anticorrosive advantage, has solved and has not possessed corrosion resistance, in the use, very easily corroded by the harmful substance among the external environment, has reduced plastic shell's life, can't carry out the problem protected to its inside object simultaneously.

In order to achieve the above object, the utility model provides a following technical scheme: the plastic shell with good corrosion resistance comprises an upper cover body and a lower cover body, wherein the surface of the bottom of the upper cover body is fixedly connected with the upper shell, the top of the lower cover body is fixedly connected with the lower shell, the lower shell comprises a shell, and the surface of the outer ring and the surface of the inner ring of the shell are both wrapped with corrosion-resistant layers.

Preferably, the outer ring of the bottom surface of the upper shell is provided with a slot, the outer ring of the top surface of the lower shell is fixedly connected with an inserting ring, and the top of the inserting ring extends to the inner cavity of the slot and is tightly matched with the inner cavity of the slot.

Preferably, the size and shape of the upper cover body are the same as those of the lower cover body, and the size and shape of the upper housing are the same as those of the lower housing.

Preferably, the four corners of the top surface of the upper cover body and the four corners of the top surface of the lower cover body are penetrated through to form positioning insertion holes, and the upper cover body, the lower cover body, the upper shell and the lower shell are made of the same material.

Preferably, the corrosion-resistant layer comprises a nickel-plated layer, the outer side of the nickel-plated layer is plated with a nitriding layer, and the outer side of the nitriding layer is covered with a GE resin protective layer.

Preferably, the material of the nickel-plated layer is nickel, and the material of the GE resin protective layer is GE resin.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses a use on resistant layer of corroding possesses corrosion-resistant advantage, can provide the protection to the surface of casing, avoids the harmful substance in the outside air or the harmful substance of aquatic to corrode the surface of casing, has prolonged the life of plastic shell.

2. The utility model discloses a lid and last lid under the setting can seal shell and last shell down, and shell and last shell merge the back under avoiding, and opposite side between them still exposes outside, makes it unable article to inside protect.

Detailed Description

Referring to fig. 1 to 4, a plastic housing with good corrosion resistance includes an upper cover 5 and a lower cover 1, wherein the surface of the bottom of the upper cover 5 is fixedly connected with an upper housing 4, the top of the lower cover 1 is fixedly connected with a lower housing 2, the lower housing 2 includes a casing 22, and the surface of the outer ring and the surface of the inner ring of the casing 22 are both wrapped with a corrosion-resistant layer 21;

the outer ring of the bottom surface of the upper shell 4 is provided with a slot 7, the outer ring of the top surface of the lower shell 2 is fixedly connected with an insertion ring 3, the top of the insertion ring 3 extends to the inner cavity of the slot 7 and is in close fit with the inner cavity of the slot 7, the upper shell 4 and the lower shell 2 are conveniently butted through the fit of the slot 7 and the insertion ring 3, and the condition of inaccurate butting is avoided;

the size and shape of the upper cover body 5 are the same as those of the lower cover body 1, and the size and shape of the upper shell 4 are the same as those of the lower shell 2;

four corners of the top surface of the upper cover body 5 and four corners of the top surface of the lower cover body 1 are provided with positioning insertion holes 6 in a penetrating manner, and the upper cover body 5, the lower cover body 1, the upper shell 4 and the lower shell 2 are made of the same material;
