Abstract

The utility model relates to the machinery field and provides a boarding gate hinge structure which comprises an upper doorframe hinge, a lower doorframe hinge and a door hinge between the two doorframe hinges, wherein through holes in the upper doorframe hinge and the lower doorframe hinge are designed to be round-shaped, a through hole in the door frame hinge are ellipse-shaped, and a door shaft of a cabin door penetrates through the through hole of the upper doorframe hinge, the through hole of the boarding door hinge and the through hole of the lower doorframe hinge sequentially in a vertical direction. Due to the fact that the through holes of the upper doorframe hinge and the lower doorframe hinge are designed to be round-shaped, the possibility that the door shaft tilts in the direction of a long shaft of the upper and lower ellipse through holes can be avoided, and the problem that poor assembly tightness of a boarding gate caused by the fall-down boarding gate can be solved.

Description

The landing gate hinge arrangement

Technical field

The utility model relates to mechanical field, relates in particular to a kind of landing gate hinge arrangement.

Background technology

Existing airframe landing gate and doorframe hinge structure are as shown in Figure 1, door hinge is clipped in up and down between two door frame hinges, in order to guarantee between door and doorframe, to possess activity degree of exceeding, the via design ovalisation on the door frame hinge up and down, through hole on the door frame hinge is circular, the hatch door door-hinge passes upper door frame hinge vias, landing gate hinge vias, lower door frame hinge vias in the vertical direction successively, realizes rotating.

Shown in Fig. 2,3, when assembling, landing gate falls under an end occurring door under the Action of Gravity Field at (or in opening process) after the unlatching, the problem such as poor sealing when closing, thus affected landing gate erection quality.

The utility model content

The technical problems to be solved in the utility model: the utility model provides a kind of landing gate hinge arrangement, effectively overcomes the landing gate fitting tight problem of poor of falling to bring under the landing gate.

The technical solution of the utility model: a kind of landing gate hinge arrangement, comprise: up and down two door frame hinges and between a door hinge, wherein, via design on the door frame hinge is circular up and down, through hole on the door frame hinge is oval, and the hatch door door-hinge passes upper door frame hinge vias, landing gate hinge vias, lower door frame hinge vias in the vertical direction successively.

The beneficial effects of the utility model: the via design on the door frame hinge is circular up and down, avoided door-hinge elliptical hole long axis direction up and down occur tilting may, effectively overcome the landing gate fitting tight problem of poor of falling to bring under the landing gate.

Description of drawings

Fig. 1 disassembles schematic diagram for having airframe landing gate and doorframe hinge structure now.

Fig. 2 is for falling schematic diagram under the existing airframe landing gate.

Fig. 3 is combined schematic diagram for existing airframe landing gate with doorframe hinge structure.

Fig. 4 is that the utility model airframe landing gate is combined schematic diagram with doorframe hinge structure.

The specific embodiment

Landing gate hinge arrangement of the present utility model, comprise: up and down two door frame hinges and between a door hinge, wherein, via design on the door frame hinge is circular up and down, through hole on the door frame hinge is oval, and the hatch door door-hinge passes upper door frame hinge vias, landing gate hinge vias, lower door frame hinge vias in the vertical direction successively.

As shown in Figure 4, the landing gate hinge arrangement improves, make the landing gate width in the whole motion process of landing gate, be in mated condition (being about to the slotted hole design is changed in the door hinge top connection by doorframe) with slotted hole all the time, via design on the door frame hinge is circular up and down, avoided door-hinge elliptical hole long axis direction up and down occur tilting may, effectively overcome the landing gate fitting tight problem of poor of falling to bring under the landing gate.

Claims

1. landing gate hinge arrangement, it is characterized in that, comprise: up and down two door frame hinges and between a door hinge, wherein, via design on the door frame hinge is circular up and down, through hole on the door frame hinge is oval, and the hatch door door-hinge passes upper door frame hinge vias, landing gate hinge vias, lower door frame hinge vias in the vertical direction successively.
