In order to overcome the problems, such as that existing hanging point lid leads to fuel tank seal failure due to dismantling repeatedly, the present invention provides
A kind of novel quick-release hanging point lid mechanism, the lid mechanism can be such that lid installation is completely separated with Oiltank structure, not only can be with
It realizes quick, the close connection of lid and housing construction, improves outer field structure disassembly efficiency, while being also avoided that due to conventional machine
Tool connects bring structural sealing problems.
Quick-release hanging point lid mechanism of the invention as shown in Figures 1 to 8, for the fast of lid mechanism and housing construction 10
Speed, close connection comprising lid 1, rotation reel 2, bottom cover 3, cam 4, locking pin 5, shaft spring 6 and locking pin spring 7.
Housing construction 10 is equipped with that the installation of lid 1 is sunk and locking pin 5 with inclined-plane installs card slot, convenient for lid 1 location and installation and
Locking.Bottom cover 3 is equipped with the sliding slot of locking pin 5.Lid 1 and bottom cover 3 are linked together by pin 9, rotate reel 2, cam
4,5 shaft spring 6 of locking pin, locking pin spring 7 are between lid 1 and bottom cover 3, and 6 sets of shaft spring in rotation 2 wild card of reel
Bounced between rotation reel 2 and bottom cover 3 for control rotation reel 2,7 sets of locking pin spring locking pin 5 outside and together
Between cam 4 and housing construction 10, and it is located in the sliding slot 31 being arranged on bottom cover 3, can be slided along sliding slot 31, and locks
Tight 5 one end of pin is thicker, and locking pin spring 7 is stuck in locking pin 5 compared between butt end and bottom cover 3, for control the flexible of locking pin 5 with
Pop-up can control the flexible of locking pin 5 by rotating cam 4, and then for controlling the quick-release hanging point lid mechanism and machine
Locking between body structure 10
It in one embodiment of this invention, further include sealing ring 8, on the surface of lid 1 Yu 10 joint of housing construction
Seal groove 11 is offered, sealing ring 8, which is placed in seal groove 11, plays the role of sealing, as shown in Figure 4.
In one embodiment of this invention, 1 center of lid is equipped with cam card slot 12, and 4 head of cam is placed in cam card
In slot 12.Specific structure is that cam card slot 12 is a perforative stepped hole, and stepped hole one end is circle, one end is rectangle, phase
4 head of cam answered is also the protrusion that the center of circle adds rectangle, and after the insertion of 4 head of cam, rectangular opening is matched with rectangle protrusion.Convex
The foot of wheel 4 is equipped with bottom cover card slot 41, and bottom cover card slot 41 is similar to " L " type of recumbency, also is provided with leading at the intermediate position of bottom cover 3
Hole, through-hole edge are equipped with bayonet lock 32 outstanding, and bayonet lock 32 is placed in " L " type bottom cover card slot 41, can be to rotation by bayonet lock 32
Reel 2 carries out rotary spacing appropriate.
In one embodiment of this invention, 4 outer rim of cam (side of cam 4 and the contact of locking pin 5) has multiple prominent
Part and depressed section out, protrusion are used to be allowed to the push-in of locking pin 5 to be inserted into housing construction 10, make lid mechanism and body
Structure 10 is relatively fixed, and depressed section is used to locking pin 5 exiting insertion housing construction under the action of locking pin spring 7
10, unlock lid mechanism with housing construction 10.
In one embodiment of this invention, the quantity of locking pin 5 is three, therefore locking pin spring 7, protrusion and recessed
Concave portion point is three.Groove on bottom cover 3 is evenly arranged, therefore locking pin 3 is also opposite is evenly arranged, 4 outer rim of cam
It is the shape of rule.It should be understood that the purpose of locking pin 5 be in order to be attached lid mechanism with housing construction 10, when
When bonding strength is inadequate, can the quantity appropriate that locking pin 5 be increased, the outer rim of cam 4 is then correspondingly improved, Yi Jiji
The hole being inserted into for locking pin 5 in body structure 10 is also correspondingly improved.
The use process of quick-release hanging point lid mechanism of the invention are as follows:, first will be among lid 1 when lid 1 needs to install
The rotation reel 2 at position presses to extreme position, rotates rotation reel 2 clockwise again later to extreme position (two pole herein
Extreme position is limited by horizontal " L " type bottom cover groove 41) after, and the installation being placed on housing construction 10 is sunk and is located, then will
Rotation reel 2 goes to extreme position counterclockwise reaches locking pin 5 in the installation card slot on housing construction 10, rotates 2 end of reel
Face is sprung back to be flushed with lid 1；When lid 1 is dismantled, it is clockwise again that rotation reel 2 thereon is first pressed into extreme position
Lid 1 is removed after going to extreme position.
Fig. 7 and it is shown in Fig. 8 be rotation reel 2 push schematic diagram, after pushing, rotate reel 2 rectangular stub branch
Cooperate with the rectangular opening inside cam 4, and is rotated together with moving cam 4.
Lid 1 in the present invention is by adjusting the rigidity and machine of locking pin 5 on the fixed housing construction 10 of three locking pins 5
Locking pin 5 installs the locking state of the adjustable lid 1 of gradient of card slot in body structure 10.
Quick-release hanging point lid mechanism of the invention is completely separated lid installation with Oiltank structure, and lid not only may be implemented
With quick, the close connection of housing construction, outer field structure disassembly efficiency is improved, while being also avoided that due to conventional mechanical connecting band
The structural sealing problems come can fundamentally solve the fuel tank Leakage due to caused by mechanical connection lid repeated disassembled and assembled, mention
High aircraft reliability of structure.
The above, optimal specific embodiment only of the invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of the claim
Subject to enclosing.
