The specific embodiment
Below in conjunction with embodiment, the utility model is elaborated.Wherein identical component represent with identical Reference numeral.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
Embodiment mono-
The anticorrosion hinge arrangement schematic diagram that Fig. 1 provides for the utility model embodiment mono-, the structural representation of the anticorrosion hinge medium-height trestle that Fig. 2 provides for the utility model embodiment mono-, Fig. 3 be in Fig. 2 E-E to sectional view, the view that the anticorrosion hinge that Fig. 4 provides for the utility model embodiment mono-is connected with automobile door cover.
The utility model embodiment mono-provides a kind of anticorrosion hinge 1, and for connecting automobile door cover 2 and body of a motor car, and automobile door cover 2 can be around hinge 1 Unscrew.This anticorrosion hinge 1 comprises body and the support 11 being fixed together, body is for being fixedly connected with body of a motor car, support 11 is for being fixedly connected with automobile door cover 2, and its fixed form can be that bolt connects, and the one side that support 11 contacts with automobile door cover 2 is provided with insulating corrosion layer 12.
Above-mentioned insulating corrosion layer 12 can be attached on support by plastic form, as shown in Figure 3, is hinge bracket 11 profiles after being coated.Preferably, the thickness of insulating corrosion layer 12 is 0.5-3mm, can play the effect with automobile door cover 2 insulation by hinge bracket 11, is not again to make insulating corrosion layer 12 too thick and affect being connected of support 11 and automobile door cover 2.
Plastic technique refers to the external surface that insulating corrosion layer 12 is wrapped in to whole support 11, thereby make support 11 on the installed surface of automobile door cover 2 one sides, also be enclosed with insulating corrosion layer 12, thereby the panel beating of having isolated support 11 and automobile door cover 2, prevents from, between automobile door cover 2 that support 11 that iron makes and mg-based material make, electrochemical corrosion occurs.
Above-mentioned anticorrosion hinge 1 can be realized being directly connected of iron and mg-based material, has solved the problem of dissimilar materials galvano-cautery, and wherein automobile door cover 2 can include but not limited to hood, luggage compartment lid, lifting door and side door.The anticorrosion hinge 1 that the present embodiment provides provides favourable condition for mg-based material is applied on hood, luggage compartment lid, lifting door and side door.
