Specific embodiment
To keep the purposes, technical schemes and advantages of the invention implemented clearer, below in conjunction in the embodiment of the present invention
Attached drawing, technical solution in the embodiment of the present invention is further described in more detail.In the accompanying drawings, identical from beginning to end or class
As label indicate same or similar element or element with the same or similar functions.Described embodiment is the present invention
A part of the embodiment, instead of all the embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to use
It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Wall card slot type connection structure is blocked to civil aircraft cargo hold of the invention with reference to the accompanying drawing to be described in further details.
As depicted in figs. 1 and 2, a kind of civil aircraft cargo hold blocks wall card slot type connection structure, blocks wall 4 for clamping cargo hold,
Diffuser 3 is connected including positive stop 1, backstop 2 and body.
It is C font plate comer pieces that body, which connects diffuser 3, by the plate A and plate B being vertically connected with the both ends plate A
It constitutes.
Positive stop 1 is the L shape angle section with reinforcing rib, which is vertically bent in the width direction by rectangle panel-like member
It constitutes, its width of two webs of composition connect that 3 plate A of diffuser is wide, and the length of two webs is then unequal with body.Reinforcing rib
It is arranged along two web of rectangle panel-like member (length direction) central axis, the reinforcing rib two sides on wherein longer web are each
Two bolts hole are set, which is arranged symmetrically about reinforcing rib.
Backstop 2 is L shape angle section, and by rectangle panel-like member, vertically bending is constituted the backstop 2 in the width direction, composition
Its width of two webs connect that 3 plate A of diffuser is wide with body, two web lengths it is equal and with the relatively stenogastry plate in front apron 1
It is isometric.Wherein along three bolts hole of web width direction spaced set on a web, wherein middle bolt fastening hole is located at abdomen
On the center line of plate length direction.
In two blocks with bolt hole a web by bolt assembly be installed on body connection 3 plate A of diffuser it is separate
The side plate B, two blocks connect 3 plate A width of diffuser with body and are overlapped setting.Another web of two blocks is oppositely arranged
And there are the gaps that wall 4 is blocked for clamping cargo hold between the two.
Card slot type connection structure of the invention connects diffuser 3 by body and connect with fuselage frame, purlin and wall panel structure, preceding
Block 1, backstop 2 are then bolted in body connection diffuser 3, and positive stop 1 and backstop 2 are formed by card slot use
The positioning of wall 4 is blocked in cargo hold.Positive stop 1, backstop 2 and cargo hold block not to be connected between wall 4, is used only as cargo hold and is blocked wall
4 positioning, distance between the two are determined according to the thickness that cargo hold blocks wall 4.The load of wall 4 is blocked by front perpendicular to cargo hold
Block 1, backstop 2 pass to body connection diffuser 3, and are finally born by airframe structure；And to block wall 4 circumferentially loaded for cargo hold
Or when deformation, body connection diffuser 3 and housing construction do not block wall 4 with cargo hold and deform, and thereby simplify body knot
The stress condition and structure design difficulty of structure.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by those familiar with the art, all answers
