Abstract
The utility model discloses an improved rainproof quick-release port cover. The port cover is provided with a button lock mounting hole; a button lock is fixed on the port cover; a button of the button lock is positioned in the mounting hole; and a sealing tape is arranged at the joint of the port cover and a port frame. The utility model can simultaneously meet the requirements on the rainproof property, quick release and pneumatic shape of the upper surface of an airplane, ensures that the pneumatic shape of a fuselage is smooth, and improves the invisibility.
Description
Technical field
The utility model relates to aeroplane structure design, is used for the improvement to rainproof lid unlatching and design form, particularly a kind of improved rainproof quick-release lid.
Background technology
On the aircaft configuration owing to the reasons such as system equipment maintenance, maintenance and use need to be offered lid usually.Lid has quick unlatching or the requirement such as for convenience detach.For this reason, usually used hinge and quick-detachable lock, plate nut class part designs lid in the past.
Airplane hatch cover has two kinds of forms usually, and a kind of is the hinge leaf lid, adopts gemel connection, is fixed to mouthful above the frame with quick-detachable lock again, and opening ways is to be flipped open take hinge as rotating shaft.This lid is because the existence of turning joint hinge, changes large place in aircraft configuration curvature, and hinge leaf can be given prominence to profile, can exert an influence to the smooth of aircraft configuration, destroys pneumaticly, if the aircraft of stealthy requirement is arranged, understanding directly affect Stealth Fighter.Simultaneously hinge leaf can be gapped between hinge leaf because the requirement of motion structure, can exert an influence to aircraft is rainproof, thereby affect the normal use of the interior equipment of lid.The rainproof common way of this class lid is at lid inner hinge hinge place sealant sealing, but this method can be paid extra aircaft configuration weight.Another kind of lid is plate nut class lid, with screw etc. lid is fixed on the plate nut on mouthful frame, this lid must use Quick dismantling tool to open, the outfield Fast-Maintenance uses inconvenience, the rainproof of this class lid is to use parts such as sealing plate nut, can pay certain weight cost.
Summary of the invention
The purpose of this utility model is, when need to offer lid for reasons such as aircraft system overhaul of the equipments and uses, lid is designed to a kind of form of not using hinge leaf and opener, when guaranteeing lid serviceable tool opened fast, satisfy the pneumatic of aircraft, stealthy and rainproof requirement.
For achieving the above object, the technical solution of the utility model is, a kind of improved rainproof quick-release lid, and lid has the button latch mounting hole, and button latch is fixed on the lid, and the button of button latch is positioned at mounting hole, and sealing band is installed on the junction of lid and mouthful frame.
Described lid is aluminum alloy materials or composite material.
Described sealing band is sealed rubber plate or teflon seal tape.
The utility model has the advantages that when the aircraft outside face was offered lid, serviceable tool can not opened fast, did not affect aerodynamic configuration, guarantee Stealth Fighter, have simultaneously rainproof function.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 be among Fig. 1 A-A to cutaway view.
Among the figure: 1-mouth frame, 2-lid, 3-sealing band, 4-button latch.
The specific embodiment
Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments, referring to Fig. 1 and Fig. 2, a kind of improved rainproof quick-release lid, lid 2 has button latch 4 mounting holes, button latch 4 is fixed on the lid 2, the button of button latch 4 is positioned at mounting hole, and sealing band 3 is installed on the junction of lid 2 and mouthful frame 1.
Described lid 2 is aluminum alloy materials or composite material.
Described sealing band 3 is sealed rubber plate or teflon seal tape.
As required, lid 2 shapes can be circle, oblong or ellipse.
According to the lid size, the aerodynamic suction size, lid 2 needs with at least 3 button latch 4 are installed.
Embodiment:A kind of best mode of the present utility model, referring to Fig. 1 and Fig. 2, a kind of improved rainproof quick-release lid has a sagging concave surface on mouthful frame 1, and its size is identical with lid 2 areas, and the sagging degree of depth is the thickness sum after lid 2 is compressed with sealing band 3.Button latch 4 on demand quantity is fixedly installed to the reverse side of lid 2, generally is installed in the arm of angle place of lid 2.Sealing band 3 is installed on the junction of lid 2 and mouthful frame 1.During locking, the tapered end of button latch 4 is pressed on mouthful frame 1, posts sealing band 3 at mouth frame 1, and lid 2 is subjected to the blocking force effect of button latch 4, and press seal band 3 is fitted its distortion, thereby reaches the rainproof requirement of lid 2 sealings.
According to lid 2 thickness, can regulate by the setting nut on the rainproof quick-release button latch, satisfy the requirement of dissimilar lid 2 designs.
The utility model can satisfy without instrument quick-release, rainproof, pneumatic and stealthy requirement.
