Novel damp-proof hinge

Abstract

The invention relates to a novel damp-proof hinge. The novel damp-proof hinge can protect screws and other fixing pieces effectively, has the damp-proof function and is protected against rust. The novel damp-proof hinge comprises a rotating shaft, a first small fan blade, a second small fan blade, a first big fan blade and a second big fan blade. The first small fan blade and the second small fan blade are respectively provided with at least two mounting screw holes. The first big fan blade and the second big fan blade cover and are fixed to the outer side of the first small fan blade and the outer side of the second small fan blade respectively. Sealing grooves are defined by protruding the periphery of the inner side of the first small fan blade and the periphery of the inner side of the second small fan blade. Sealing gaskets are arranged around the peripheries of the inner sides of the sealing grooves. The first small fan blade and the second small fan blade are respectively provided with two through holes. The through holes are filled with activated carbon. Water partition screens are arranged on the outer sides of the through holes. Sealing rings are further arranged on the positions of the mounting screw holes. The first small fan blade and the second small fan blade are further provided with a plurality of clamping holes. The inner sides of the clamping holes protrude outwards to form a clamping base. The positions, corresponding to the clamping holes, of the inner side of the first big fan blade and the inner side of the second big fan blade are provided with inserting blocks. The inserting blocks are fixed in the clamping holes in a clamping mode.

Description

technical field [0001] The invention relates to a connecting piece, in particular to a novel moisture-proof hinge. Background technique [0002] As we all know, a hinge, commonly known as a hinge, is a device used for connection or rotation, which can make doors, covers or other swinging parts rotate, and is widely used in fields such as home building materials; hinges in the prior art usually include shafts and There are two hinges, and there are at least two screw holes on the hinges. When installing, drill holes in the door, cover or other swinging parts, and then install the hinges on them with screws; , the screw ends are usually exposed outside, and there are no protective parts. When encountering wet weather or being exposed outdoors, the fixing parts of this hinge, such as screws, are prone to rust problems, and there are safety hazards such as unstable fixing. . [0003] In view of the above-mentioned defects, the designer actively researches and innovates, in ord...
