Detailed description of the invention four: combine Fig. 1, Fig. 2 and Fig. 5 and present embodiment is described, the spring strut 23 of present embodiment is
Rectangular spring cylinder.It is arranged such, is on the one hand the reciprocal fortune belonging on straight line due to the motion of slide block in slider-crank mechanism
Dynamic, rectangular spring strut is easy to retrain slide block, in order to avoid rotating during slide block movement, causes slide block and spring strut
Inwall generation friction self-locking and then cause hinge failure；On the other hand rectangular spring cylinder is easy to the motion of restricted spring bar, protects
Having demonstrate,proved spring lever can only translation, it is to avoid spring lever rotates so that the locking of spring lever can smoothly complete.Other composition and
Annexation is identical with detailed description of the invention one or three.
Detailed description of the invention five: combine Fig. 1, Fig. 2 and Fig. 5 and present embodiment is described, the spring strut 23 of present embodiment
Rectangular spring cylinder is provided with groove.Being arranged such, main purpose is easy for spring leaf when being shifted onto extreme position by spring lever,
In card entry slot so that spring lever locks；Without this groove, after spring lever is pulled to extreme position, slide block turns to, bullet
Spring base can promote slide block, and then the expansion of promotion hinge, serve the purpose contrary with this invention under the thrust of straight spring.
Other composition is identical with detailed description of the invention one or four with annexation.
The operation principle of the present invention is:
When development mechanism is started working in space, public hinge 3 is relatively fixed, and the energy being stored in scroll spring 1 starts to release
Put, drive mother's hinge 4 and adapting rod 2 to rotate around the axis of hinge axis 8, drive adapter 9 around hinge axis 8 simultaneously
Axis rotates, and owing to Large Gear Shaft 10 and adapter 9 are to be connected relation by bearing pin 26, Large Gear Shaft 10 also can be with switching
9 rotate, and then drive and gear wheel 11 that Large Gear Shaft 9 connects with flat key and the pinion shaft that engages with gear wheel 11
12 rotate.Crank 15 is connected on pinion shaft 12 by square hole and nut, and rocking bar 17 and crank 15 can be around cranks
Axle 16 is freely rotatable, and rocking bar 17 can also be freely rotatable around rocker shaft 21, when scroll spring 1 is by adapting rod 2 and mother
Hinge 4 drive adapter 9, and then when driving Large Gear Shaft 10, gear wheel 11 and pinion shaft 12 to rotate, motion is passed
On slider-crank mechanism, the input of slider-crank mechanism is the rotation of pinion shaft 12, and the result of output is that slide block 22 exists
Reciprocating translatory on center line in spring strut 23.When slide block 22 moves back and forth in spring strut 23, spring strut 23 can be promoted
The spring lever 19 being cased with straight spring 18 at two ends, when slide block 22 is to left movement, can promote the spring lever 19 in left side, constantly
The ground wedging ring straight spring 18 on spring lever 19, owing to the elastic force of straight spring 18 increases along with the increase of the deformation of compression,
At this time straight spring 18 can produce the resistance of a continuous increase to spring lever 19 and slide block 22.Until slide block 22 is transported to the left
Moving extreme position, owing to being fixed with spring leaf 20 on spring lever 19, now spring leaf 20 is understood due to its own resilient effect,
Snap in the groove of spring strut 23 so that spring lever 19 and straight spring 18 are locked so that part energy is stored in left side
In straight spring 18, owing to slide block 22 and spring lever 19 are without annexation, and slide block 22 moves to extreme position to the left,
After spring lever 19 and spring 18 are locked, slide block 22 starts to move right.When slide block 22 moves right, equally can
Spring lever 19 on the right side of promotion, wedging ring spring 18 on spring lever 19, until moving to extreme position, spring together
Spring leaf 20 on bar 19 snaps in the groove of spring strut 23, and spring lever 19 and spring 18 are locked so that other one
Divide energy storage in the straight spring in right side 18.Then slide block 22 continues to move back and forth, until hinge launches to put in place, completes lock
Fixed.From the angle of mechanics, hinge is during launching, by the transmission of motion so that slide block produces and moves back and forth, and is sliding
In block motion process, two straight springs are sequentially generated the resistance of constantly increase, until spring is locked, and the resistance that straight spring produces
Power can greatly reduce the movement velocity of slide block, and then the development rate of reduction hinge, reduces the locking impact launching end.
Although the present invention is disclosed above with preferred embodiment, but it is not limited to the present invention, those skilled in the art
Other changes can also be done in spirit of the present invention, and be applied in the NM field of the present invention, certainly, these foundations
The change that present invention spirit is done all should be included in scope of the present invention.
