Embodiment
The utility model is applied to the lid with automatic closing function.This lid is after aircraft plug from falling, non-
Human intervention situation the lower flap can close automatically.And buried in using and turn round chip type spring and sliding track lock, there is dust-proof heat resistance
Can, reliable lock is high.
As shown in Figure 1, 2, closed automatically using the slide rail locking-type aircraft of twisted piece spring hinge the utility model proposes a kind of
Remain silent lid, it is characterised in that including：Mouth frame 1, cover plate 2, twisted piece spring hinge component and slide rail lock set；One end of cover plate 2 passes through
Twisted piece spring hinge component is connected with mouth frame 1 so that cover plate 2 overturns and is bonded with respect to mouthful frame 1；During fitting, the other end of cover plate 2 leads to
Cross slide rail lock set and realize locking with mouth frame 1.
One end that cover plate 2 is connected by twisted piece spring hinge component with mouth frame 1, is provided with hollow round tubular structure, and this is hollow
The one end open of round tube shape structure, cylindric indent is provided with, the other end is a cylindric protrusion, and is set in the cylindric protrusion
It is equipped with stopper slot.
Steel wire torsion spring is replaced using twisted piece spring, is built in lid rotating shaft, is formed integrally the hinge of formula.Twisted piece spring is according to mouth
The driving force size of lid, combined from the high-strength hot processing spring steel plate of different-thickness.In flight course, spring does not have
Have in harsh flight environment of vehicle, improve the solar heat protection ability of lid.As shown in Figure 4,5, twisted piece spring hinge component includes
Twisted piece spring component 3, torsion spring fixed seat 4 and torsion spring blanking cover 6；
Twisted piece spring component 3 is arranged on the hollow round tubular inside configuration, and one end of twisted piece spring component 3 passes through the circle
The stopper slot set in column protrusion carries out circumferential spacing, and the cylindric protrusion is engaged and cylindric convex with torsion spring blanking cover 6
Go out and rotated in torsion spring blanking cover 6；
The other end of twisted piece spring component 3 is extend into torsion spring fixed seat 4, passes through the cylindric knot of the protrusion of torsion spring fixed seat 4
The stopper slot set in structure carries out circumferential spacing, the protrusion cylindrical-shaped structure of torsion spring fixed seat 4 and the hollow round tubular structure
The cylindric indent of one end be engaged；
Torsion spring fixed seat 4 and torsion spring blanking cover 6 are fixedly mounted on mouthful frame 1.
Stack to be formed as shown in figure 5, the twisted piece spring component 3 is multi-disc identical strip spring steel plate.Spring steel plate
Spring steel plate is handled from high-strength hot, thickness and size selection can be carried out according to the size and driving force of lid.
As shown in figure 3, the slide rail lock set includes lock 9, lock housing 10, dead bolt 11, lock body blanking cover 12, spring 13 and drawn
Bar 14；Lock 9 is fixed on mouthful frame 1, is fixed on 9 relative lock housings 10 of lock on cover plate 2, pull bar 14 sequentially passes through lock body and blocked up
Lid 12 and spring 13, are fixedly connected with dead bolt 11, are placed in lock housing 10, and lock body blanking cover 12 is connected by screw thread and lock housing 10.Lock
Body blanking cover 12 can ensure that inside lock body be closing space, avoid fifth wheel from entering, have dust reduction capability.
Lock housing 10 is stretched out in the end of dead bolt 11, and there is fillet the end of dead bolt 11.Cooperation between dead bolt 11 and lock housing 10
Gap is 0.5mm, make dead bolt 11 in lock housing 10 slidably.The axis of lock housing 10, pull bar 14 and dead bolt 11 is overlapped, and operation is drawn
Bar 14 is changed to Straight pull, avoids the side force for being opened and closed lid from influenceing dead bolt 11 and slides, and pull bar 14 and dead bolt 11 are in same cunning
On dynamic rail road, stress is more rationally uniform.Fit clearance between pull bar 14 and lock body blanking cover 12 is 0.5mm.Dead bolt 11 and lock
Button 9 carries out chromium plating process, improves the hardness and smoothness of contact surface, and it is smooth to ensure that dead bolt 11 slides.
Operation principle
In use, cover plate is opened certain angle by external force, the cover plate being now connected with twisted piece spring component both ends is cylindric convex
Going out the stopper slot of interior setting and circumferentially opposed motion occurs for the stopper slot of torsion spring fixed seat, twisted piece spring component twists deformation,
The driving force of opposite direction is produced to cover plate, so that cover plate returns to initial position.When cover plate moves to certain position, dead bolt
Contacted with lock, both contact surfaces are separately designed as fillet and inclined-plane.Lock is integrally fixed on mouthful frame, can not be moved, institute
It is compressed into dead bolt in dead bolt and lock relative movement in lock body.When cover plate, which moves to, to be contacted with mouth frame, dead bolt with
Lock no longer contacts.Now dead bolt moves out in the presence of lock body inner spring power, returns to initial position, and in lock
Constraint lower cover can not continue to move, so as to realize that lid locks.
