Description

Boarding gate

Technical Field

The utility model belongs to the small-size aircraft hatch door field, concretely relates to gate of boarding.

Background

In the flying process of the airplane, the special environment of the airplane has higher requirement on the strength resistance of the gate, however, at present, the gate of the small airplane consists of an outer skin and an inner basin-shaped part, and the inside of the gate is hollow, so that the outer skin is easily sunken or even damaged, and great potential safety hazard is brought to the flying process.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 3, the present embodiment provides a gate, which mainly comprises an outer skin 1, an inner basin-shaped member 2, a ventilation window 3, a hinge, a sealing tape 6, and the like.

The outer skin and the inner basin-shaped piece are frameworks of the gate, and as the lock mechanism is positioned between the inner basin-shaped piece and the outer skin, 3 through holes are formed in the inner basin-shaped piece to serve as passages for mechanism installation and maintenance, and meanwhile, the basin-shaped piece is also reinforced around the perforated area. In order to improve the rigidity of the door, a circular reinforcing socket is designed in the middle of the inner basin-shaped piece, and the bottom surface of the reinforcing socket is tightly attached to the outer skin and riveted with the outer skin to form a whole.

The appearance around the gate is relatively straight, so that the gate is suitable for adopting an external hinge. According to the size and the weight of the door, two hinges are arranged for the boarding door, the upper hinge 4 is close to the ventilation window, and the lower hinge 5 is located near a round angle at the front lower part of the outer skin. In order to further improve the stability of the boarding door, the hinge axis is close to the appearance of the machine body in front of the boarding door, the intersection point of the upper hinge plane and the hinge axis is 4.9 mm far away from the theoretical appearance of the machine body, and the intersection point of the lower hinge plane and the hinge axis is 9.5 mm far away from the theoretical appearance of the machine body. The hinge connected to one side of the cabin door is formed by bending a stainless steel plate, and the part connected to one side of the cabin body is a stainless steel machining part.

In order to prevent the entry of rainwater and to ensure that the boarding door is not ventilated all around during flight, sealing strips are arranged on the periphery of the door. The sealing tape is made of sponge rubber material, the material has larger compression deformation and good rebound resilience, and can effectively meet the sealing requirements of different parts of the circumference of the cabin door. The sealing strip is bonded at the round angle of the periphery of the basin-shaped piece through adhesive.

In order to reduce the processing cost of the inner basin-shaped part, the material is changed from aluminum alloy into composite material, the part thicknesses are different in different regions, the thickness of the central region is 0.964 mm, the thickness of the outermost ring region is 1.446 mm, and the thickness of a transition region sandwiched between the two regions is 1.205 mm.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
