Abstract
The utility model provides the attachment structure between a kind of fixed leading edge segmentation, two fix two dividing plates (3) of setting at leading edge segmentation, dividing plate (3) is the L-shaped angle section in section, two dividing plates (3) are oppositely arranged on both sides and fixed in leading edge, edge strip part in wherein two dividing plates (3) is mutually away from placement, gap is left between fixing leading edge in both sides, rubber tube (2) is set in gap, rubber tube (2) is made up of O-shaped rubber ring and two rubber strips collinearly arranged being symmetricly set in O-shaped rubber ring, O-shaped rubber ring is inlaid in both sides and fixed between the gap of leading edge, two rubber strips are plugged between the skins front edges in fixed leading edge (1) and dividing plate (3), dividing plate (3), rubber strip and skins front edges (1) three are detachably connected.The utility model provides attachment structure, with the relative motion between deformation-compensated every section fixed leading edge of rubber tube, makes every section of fixed leading edge structure independent stressed, reduces local stress, mitigates construction weight.
Description
Technical field
The utility model belongs to aviation wing structure design field, and in particular to the connection knot between a kind of fixed leading edge segmentation
Structure.
Background technology
It is the fixed part in wing structure before front-axle beam that wing, which fixes leading edge, is primarily subjected to aerodynamic loading and becomes with wing
Stress caused by shape, rigidity Design is mainly considered during design.Wing fixes leading edge and considers the factors such as material, technique, is designed to
Segmental structure, the fixed leading edge segmentation of tradition are connected as an entirety, leading edge entirety stress by docking dividing plate, it may appear that local to answer
Power is high, construction weight weight.
Utility model content
The purpose of this utility model is to provide the attachment structure between a kind of fixed leading edge segmentation, overcomes or alleviated by existing skill
At least one drawbacks described above of art.
The purpose of this utility model is achieved through the following technical solutions：A kind of attachment structure between fixed leading edge segmentation, two
Two dividing plates are set at the fixed leading edge segmentation, and two dividing plate fixes the skeleton of leading edge respectively as both sides, before both sides are fixed
It is intermarginal to leave gap, rubber tube is set in the gap, before the rubber tube is fixed in leading edge by detachable fastener and both sides
Edge covering and dividing plate are connected.
Preferably, the dividing plate is the L-shaped angle section in section, and two dividing plates are oppositely arranged on the both sides and fix leading edge
On, wherein the edge strip part in two dividing plates is mutually away from placement.
Preferably, the rubber tube is by O-shaped rubber ring and what is be symmetricly set in O-shaped rubber ring two collinearly arrange
Rubber strip is formed, and O-shaped rubber ring is inlaid in the both sides and fixed between the gap of leading edge, and two rubber strips are plugged in fixed leading edge
In skins front edges and dividing plate between, dividing plate, rubber strip and skins front edges three are connected by detachable standard component.
The beneficial effect of attachment structure between a kind of fixed leading edge segmentation provided by the utility model is, fixes leading edge
Certain interval is left between segmentation, centre is connected using rubber tube, between deformation-compensated every section fixed leading edge of rubber tube
Relative motion so that every section of fixed leading edge structure independent stressed, short with wing-box connecting length, deform with wing caused by
Stress influence area reduces, so as to mitigate construction weight；Gap between every section of fixed leading edge is compensated using rubber tube, while can be with
Play sealing function.
Brief description of the drawings
Fig. 1 is the structural representation for the attachment structure that the utility model is fixed between leading edge segmentation.
Reference：
1- skins front edges, 2- rubber tubes, 3- dividing plates.
Embodiment
To make the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Accompanying drawing in embodiment, the technical scheme in the embodiment of the utility model is further described in more detail.In the accompanying drawings, from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Described reality
It is part of the embodiment of the present invention to apply example, rather than whole embodiments.Embodiment below with reference to accompanying drawing description is to show
Example property, it is intended to for explaining the utility model, and it is not intended that to limitation of the present utility model.Based in the utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made,
Belong to the scope of the utility model protection.
The attachment structure fixed leading edge segmentation of the present utility model is described in further details below in conjunction with the accompanying drawings.
As shown in figure 1, the attachment structure between a kind of fixed leading edge segmentation, two fix two dividing plates 3 of setting at leading edge segmentation,
Two dividing plates 3 are oppositely arranged on both sides and fixed in leading edge, fixed respectively as both sides by the dividing plate 3 from the L-shaped angle section in section
The skeleton of leading edge, wherein the edge strip part in two dividing plates 3 is mutually away from placement.Both sides fix leading edge between leave certain interval,
Rubber tube 2 is set in gap, and the rubber tube 2 is from by O-shaped rubber ring and two conllinear arrangements being symmetricly set in O-shaped rubber ring
Rubber strip form pattern, O-shaped rubber ring part be inlaid in both sides fix leading edge gap between, two rubber strips are plugged in
Between skins front edges 1 and dividing plate 3 in fixed leading edge, dividing plate 3, rubber strip and the three of skins front edges 1 pass through detachable fastening
Part is connected (common detachable standard component can be selected in the detachable fastener), is connected so that rubber tube 2 fixes leading edge with both sides.That is rubber
The rubber strip of sebific duct 2 is connected on the edge strip of two dividing plates 3, and skins front edges 1 are covered on the outside of the rubber strip of rubber tube 2, with can
Standard component connection is unloaded, the middle O-shaped rubber ring portion extrusion of rubber tube 2 is between two dividing plates 3.It is deformation-compensated with rubber tube 2
Relative motion between every section of fixed leading edge, make every section of fixed leading edge structure independent stressed, reduce local stress, mitigate structure weight
Amount, while play sealing function.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in
Change or replace, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with described
Scope of the claims is defined.
