Description
Technical field
This application involves airplane design, being the one kind being quickly turned on and off for large-scale lid on aircraft has sealing work(
The quick-detachable lock of energy.
Background technology
The quick-detachable lock used on aircraft at present is made of screw, pin, locating snap ring, latch, cone, lock, spring.It is existing
Have technology the problem is that, quick-detachable lock upper lock body be mounted on lid on, quick-detachable lock screw mounting hole is provided in lid, by quick-release
Lock function limits, and screw bore dia is more than screw diameter, causes upper lock body screw and lid joint gap larger, same to lock at present
Body bottom is open type structure, does not close, and the pin movement slots that rainwater can be between screw and lid on gap and screw are penetrated into
To inside nacelle, cause not sealing at quick-detachable lock.So design is a kind of quick-release but also realizing the quick-detachable lock of sealing function
It is the key that certain type machine development.
Invention content
For the defect for overcoming existing quick-detachable lock that can not seal, the application provides a kind of improved quick-detachable lock, not only has
There is a quick-detachment function, and being capable of effective solution seal defect this problem.
A kind of quick-detachable lock of airplane hatch cover, containing upper lock body and down lock body, upper lock body is fixed in lid, and down lock body is solid
It is scheduled on airframe, upper lock body contains lock core, locating snap ring and upper cone, and locating snap ring is located at the upper surface of upper cone, lock core edge
In the centre bore of locating snap ring and upper cone, down lock body contains lower cone and lock, it is characterised in that：In the stop of upper lock body
Ring surface is equipped with one layer of rubber sheet gasket, sets that there are one annular grooves on the outside of the conical surface of upper cone, and annular groove is embedded with sealing ring, described
Lower cone bottom be closed U-shaped structure.
The advantages of above-mentioned technical proposal, is：On former quick-release lock construction, improvement, upper lock body are sealed to upper down lock body
The increased rubber sheet gasket in outer surface, prevents rainwater from entering inside nacelle from the gap of upper lock body screw Yu lid joint, locking
Increased O-ring seal can further prevent rainwater from entering short at the taper surface that the upper cone of body and the lower cone of down lock body screw
Cabin；And the improvement of down lock body bottom seal, it can directly prevent rainwater from flowing into inside nacelle, and ponding is sealed up for safekeeping inside lock body,
Facilitate follow-up cleaning.
The application is further illustrated with reference to the accompanying drawings and examples.
Description of the drawings
Fig. 1 is the structural profile signal of airplane hatch cover quick-detachable lock.
Fig. 2 is the signal of upper lock body structural profile.
Fig. 3 is the signal of down lock body structural profile.
Fig. 4 is the application signal of airplane hatch cover quick-detachable lock.
Explanation is numbered in figure：Under 1 upper cone, 2 screws, 3 pins, 4 latch, 5 springs, 6 rubber sheet gaskets, 7 locating snap rings, 8
Cone, 9 locks, 10 sealing rings, 11 rivets, 12 lids, 13 airframes.
Specific implementation mode
Referring to attached drawing, a kind of quick-detachable lock of airplane hatch cover, containing upper lock body and down lock body, upper lock body is fixed on lid 12
Inner surface, down lock body are fixed on airframe 13, and upper lock body contains lock core, locating snap ring 7 and upper cone 1, and locating snap ring is located at upper
The upper surface of cone, lock core are embedded in the centre bore of locating snap ring and upper cone, the lock core contain screw 2, pin 3 and
Latch 4 and spring 5, down lock body contain lower cone 8 and lock 9, and one layer of rubber sheet gasket is equipped in the stop ring surface of upper lock body
6, the conical surface outside of upper cone 1 is set there are one annular groove, and annular groove is embedded with sealing ring 10, and it is preferably O shapes to implement sealing ring 10
The bottom in section, the lower cone is closed U-shaped structure.
When assembly, the rubber sheet gasket 6 for external surface of locking is directly installed on 12 inner surface of lid, with locating snap ring 7 and epicone
Body 1 is connect by rivet 11 with lid 12, and the spring 5 of upper lock body is placed in lower part in screw 2, and 2 other end of spring connects with pin 3
It touches, pin 3 is inserted into screw 2, and latch 4 is inserted into the intermediate throughholes of pin 3, and O-ring seal 10 is mounted on upper cone 1 and lower cone
It at the joint surface of body 8, and is fixed on upper cone 1, screw 2 is a tight fit in locating snap ring 7, rubber sheet gasket 6, upper cone 1 later
Inside.Lower cone 8 is inserted into the through-hole of lock 9, and lock 9 is connected by rivet with the nacelle grid beam of airframe 13.
During use, when lid is closed, screw 1 and the down lock body of lock core are tightened, rubber sheet gasket 6 and mouth
Interior surface fits closely, and effectively prevents rainwater and is flowed into nacelle from upper lock body screw 1 and 12 joint gap of lid.Upper
O-ring seal 10 at down lock body joint surface, the rainwater that can obstruct inflow pin hole enter inside lock body.Meanwhile lower cone 8
Bottom lock formula structure, further by penetrate into nacelle inside ponding seal up for safekeeping in the bottom of down lock body, to realize quick-detachable lock
Sealing function.
