Description
Technical field
The utility model is related to a kind of quick-release opening cover devices, belong to technical field of aircraft structure design.
Background technology
Section nacelle positions blending bolt connection by the cooperation of screw rod and mounting hole and fixes, but nacelle before and after certain gun pod
Front and rear section has covering covering, and no installation connecting path need to open up lid, and lid near two sections of nacelle join domains thus
Should there are opening character as big as possible and quick-detachment function to meet installation reachability requirements.
The utility model structure type is simple, and the connection mode of lid and nacelle is novel, can be installed for structure and provide dress
With access, while there is the limiting locking of quick-release and fastener.
Related patents are retrieved：A kind of quick-release lid（CN201923316U）, a kind of quick-release opening cover device
（CN105217014B）.
Invention content
The purpose of this utility model is that above-mentioned two assemblies airtight space is solved the problem of without installation connecting path, if
Meter is a kind of to provide operating space for assembling and dismantlement work, has the function of the quick-release lid dress of quick-release and fastener limiting locking
It puts.
The utility model to achieve these goals, adopts the following technical scheme that：
A kind of quick-release opening cover device, section nacelle is connected by undersetting body before and after gun pod, and undersetting external surface is
Nacelle external surface；Centre has a rectangular aperture to provide access for the connection installation of nacelle, and connection is completed, is closed by lid；
Lid one end is connected with fork ear, and the other end is connected with quick-release lock shell, so as to fulfill the quick-release opening and closing movement of lid；
Lid side is arranged with step, is directly overlapped on undersetting body, is fixed on one side with fork ear riveting, another side leads to
The auricle for crossing quick-release lock shell is connect with undersetting body, so as to which the connection for controlling lid is fixed.
Assembly work is completed, and after lid is closed, the fork ear being attached thereto can also limit turning for front and rear section nacelle attaching nut
It is dynamic.
Further, the compressed spring axially inward of the pin in lid.
Further, bolt is located in the card slot of quick-release lock shell.
The beneficial effects of the utility model：
The utility model provides access, and realize Fast Installation fixing and demolition for installation, the dismounting of two closed assemblies
The function of assembly.

Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：A kind of quick-release opening cover device, section before and after gun pod
Nacelle is connected by undersetting body 3, and 3 outer surface of undersetting body is nacelle external surface；
1 one end of lid is connected with fork ear 8, and the other end is connected with quick-release lock shell 4, so as to fulfill the quick-release opening and closing movement of lid；
1 side of lid is arranged with step, is directly overlapped on undersetting body 3, is fixed on one side with the fork riveting of ear 8, another
While the auricle by quick-release lock shell 4 is connect with undersetting body 3, so as to which the connection for controlling lid is fixed.
First with tool by compressed spring 2, and being rotated out of quick-release lock shell 4 card slot together with bolt 6 axially inward of pin 7
90 °, the extraction outward of pin 7, lifts lid 1 with a small angle inclination, treats the fork ear 8 being connect with lid from undersetting body 3 at this time
Inner cavity is fully removed, lid 1 can Unscrew, so as to for nacelle provide installation space；It, will after the completion of installation and maintenance sex work
Lid 1 is rotated to 3 opening of undersetting body, and slight inclination makes 8 one end of the fork ear being attached thereto be inserted in the inner cavity of undersetting body,
It treats that 1 both sides step of lid is bonded completely with undersetting body 3, tightens pin 7, be rotated by 90 °, bolt 6 is made to be located at quick-release lock shell 4
In card slot；Lid both sides step, the fork ear 8 being connect with lid and quick-detachable lock collective effect ensure that the connection of lid 1 is fixed, i.e.,
Lid 1 can be closed reliably, fork ear 8 can also limit the rotation of front and rear section nacelle attaching nut.
