Description

Hinge water-proof and drainage structure of connecting port cover

Technical Field

The utility model belongs to the mechanical design field specifically is a hinge waterproof structure who connects the flap.

Background

The flap has wide application, such as in aircraft body structures, and the flap is used for installation, observation, maintenance and the like of equipment. The connection between the cover and the machine body structure has various forms, such as a hinge, a quick-release lock and the like. When the hinge connection mode is adopted, the traditional waterproof sealing measures such as the spreading of sealing belts or sealants between the cover cap and the machine body structure cannot meet the waterproof requirement of the hinge cover. Because there is inevitable clearance between the hinge structure, the rainwater can get into the organism through the gap of hinge inside, not only can cause the corruption of organism structure, more can influence the normal use of interior electronic equipment of organism. Because the hinge needs to be opened and closed in a rotating mode, the traditional waterproof sealing measures such as a sealant or a sealing gasket cannot meet the waterproof requirement of the hinge, and special waterproof and drainage design needs to be carried out on the installation position of the hinge.

Disclosure of Invention

For solving the not enough of above-mentioned prior art existence, the utility model provides a technical problem who solves provides a hinge waterproof structure of connector flap to solve the infiltration problem of the connection hinge department of flap and organism.

In order to solve the technical problem, the designed hinge waterproof and drainage structure for connecting the opening cover mainly comprises a hinge sheet, a poker, a sealing belt and an opening cover, wherein an opening frame is additionally arranged outside the hinge sheet, and the sealing belt is paved at the gap between the opening frame and the hinge sheet, the opening cover and the outer skin of the opening frame; a water accumulation groove is designed at the mounting position of the inner hinge sheet and the poker, the water accumulation groove is designed according to the appearance structure of the inner hinge sheet, the depth of the water accumulation groove is adapted to the thickness of each structure of the hinge, and the water accumulation groove is deepest at the poker; the deepest point of the water accumulation groove at the poker is provided with a drainage groove, water flowing into the water accumulation groove of the opening frame is drained to the overlapping position of the opening frame and the skin through the drainage groove, and the water is discharged outside the machine body through the overlapping gap of the skin.

The inner hinge sheet arranged in the opening frame is connected with the machine body structure through a rivet, and the inner hinge sheet is connected with the opening cover through a rivet.

In the technical scheme, the designed hinge waterproof and drainage structure connected with the cover realizes the waterproof of hinge gaps by improving the opening frame structure, does not need to increase an additional structure, has simple sinking structure of the increased opening frame, is easy to form, does not influence the assembly, and effectively avoids the influence of water stains on the corrosion of the internal structure of the machine body and electronic equipment.

Drawings

Fig. 1 is a schematic view of a hinge waterproof and drainage structure of a connecting cover.

In fig. 1: 1. the mouth frame, 2, hinge pieces, 3, a poker, 4, inner hinge pieces, 5, a sealing strip, 6, a mouth cover, 7, the mouth frame outer skin, 8, a drainage groove, 9, the outer skin and 10 a water accumulation groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to fig. 1, and it is obvious that the described embodiments are only a specific embodiment of the present invention, but not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.

As shown in figure 1, a water accumulation groove 10 with proper size is designed at the mounting positions of a hinge plate 2, a poker 3 and an inner hinge plate 4 of an opening frame 1, the depth of the water accumulation groove 10 depends on the thickness of each structure of the hinge, particularly, the depth of the water accumulation groove 10 at the poker 3 is the largest, so a drainage groove 8 is designed at the lowest point of the water accumulation groove 10 at the poker 3. The hinge plate 2 is arranged between the opening frame 1 and the opening frame outer skin 7 and is connected through a rivet; the inner hinge plate 4 is riveted with the flap 6. Water penetrating through the hinge structure gap flows into the water accumulating groove 10 of the opening frame 1, flows to the lap joint of the opening frame 1 and the outer skin 9 through the drainage groove 8, and is discharged outside the machine body through the skin lap joint gap. In addition, a sealing belt 5 is laid in the gap between the opening frame 1 and the inner hinge sheet 4, the opening cover 6 and the opening frame outer skin 7, so that the waterproof sealing effect of the opening cover 6 is ensured.
