Abstract
The utility model belongs to aircraft door mechanism design technology, relates to a kind of hatch door bolt mechanism.A kind of aircraft door bolt mechanism, is characterized by: described hatch door bolt mechanism comprises door bolt (4) and lining (5), and described door bolt (4) bottom is scabbled; Described lining (5) is inner with plane; Described door bolt (4) is through the lining be arranged in basic structure (5), and the plane of described lining (5) inside matches with the base plane of door bolt (4).The utility model simply uses, and is designed with very strong versatility for bolt mechanism.
Description
Technical field
The utility model belongs to aircraft door mechanism design technology, relates to a kind of hatch door bolt mechanism.
Background technology
The hatch door part that on aircraft, size is little have employed bolt mechanism, and door bolt has pole shape, through the door body structure press-fiting standard lining, also have a kind of, in order to hatch door locking and control cabinet door handle power, round bar shape door bolt bottom is scabbled, equally through the door body structure press-fiting lining.See Fig. 1, conventional door bolt 2 is round bar shape door bolt, and the frictional force between itself and lining is comparatively large, affect handle power, and the door bolt that bottom is scabbled exists gap, and when door bolt moves along door bolt axis of movement 1, stroke is comparatively large, likely with lining self-locking, interferes.
Utility model content
The purpose of this utility model is: provide a kind of aircraft door bolt mechanism, can prevent bottom from scabbling door bolt rotational problems when door bolt coordinates with lining, prevent door bolt and lining from interfering rear self-locking simultaneously.
The technical solution of the utility model is: a kind of aircraft door bolt mechanism, is characterized by: described hatch door bolt mechanism comprises door bolt 4 and lining 5, scabbles bottom described door bolt 4; Described lining 5 inside is with plane; Described door bolt 4 is through the lining 5 be arranged in basic structure, and the plane of described lining 5 inside matches with the base plane of door bolt 4.
The utility model has the advantages that: the utility model is by improving the shape of conventional door bolt 2, and use the inner lining with plane, ensure that door bolt can not rotate in lining 5 again, simultaneously because the plane of lining 5 inside coordinates with the base plane of door bolt 4, there is not comparatively wide arc gap, so ensure that and self-locking can not occur.The utility model simply uses, and is designed with very strong versatility for bolt mechanism.
Accompanying drawing explanation
Fig. 1 is that conventional door bolt interferes self-locking schematic diagram with lining
Fig. 2 is that door bolt in the utility model and lining and lock ring assemble schematic diagram;
Fig. 3 is the lining cross sectional shape in the utility model;
Wherein, 1-fastens axis of movement, the conventional door bolt of 2-, 3-lock ring, 4-door bolt, 5-lining, 6-door body structure with a bolt or latch.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
See Fig. 2, Fig. 3, in the utility model, door bolt and lining mating surface need to carry out surface treatment through lubricating process, reduce frictional force.During installation, lining 5 is pressed into door body structure 6, and door bolt 4 matches with lining, and door bolt scabbles bottom and finally coordinates with lock ring 3.
Large-scale military transportation airplane rear lower plant maintenance bolt uses the utility model hatch door bolt mechanism, and assembling is simple, and processing cost is lower; Effectively solve the contingent door bolt Rotation of conventional bolt mechanism and locking phenomenon.The hatch door bolt mechanism of civil aircraft, Special Aircraft also can be this mode.
