Abstract
The utility model belongs to aviation lifesaving field, is related to a kind of firing lock for ejector seat.Including upper connector, striker, lower connecting rod, pull rod, safety plug, spring, the upper connector and lower connector are connected through a screw thread, and inside is that other parts provide installation space, and there are the interfaces being connect with igniter other spare parts for outside；Striker is fixed on by inclined-plane in connector and lower connector with pull rod；Spring is located between striker and lower connector；The safety plug for playing safety effect is located in striker and lower connector matching hole；Remove safety plug before work, when work, pull rod drives striker to move out, compressed spring, when the limiting holes for being engaged inclined-plane and pulling out lower connector of pull rod and striker, the separation of occlusion inclined-plane, striker is discharged, percussion function is completed in compressed spring driving striker movement.This firing lock structure is more than you know, solves the problems, such as spring in the vacation of igniter, and does not increase the workload safeguarded and used, securely and reliably.
Description
Technical field
The utility model belongs to aviation lifesaving field, is related to a kind of firing lock for ejector seat.
Background technology
The firing lock of the long distance igniter of current various ejector seat is using the driving that releases energy after compressed spring
Striker, the fixed form of striker steel ball lock, structure referring to Fig. 1, include mainly connector 7, shell 8, striker body 9, striker 11,
Safety plug 5, spring 6 have steel ball 10 on striker body 9；Shell 8 is cylinder revolution, and there is large and small two anchor rings striker 11 in inside
Left end has annular groove, steel ball 10 to consolidate striker 11 and striker body by the big inner ring surface of shell 8 and the annular groove of striker 11
It is fixed.When work, safety plug 5 is pulled up, striker 11 moves to the right with striker body 9, compressed spring 6, when steel ball 10 is detached from shell
The big anchor ring of body 8, striker body 9 release the fixation with striker 11, are moved downward under the driving of spring 6, complete percussion function.
Its disadvantage is referring to Fig. 2：Firing lock needs first to carry out spring before not working, and there are spring in vacation, striker body 9 is unreliable solid
It is fixed, safety plug 5 is pulled up, striker body 9 can move the possibility for causing surprisingly to work, influence the safety safeguarded and used.
Invention content
Goal of the invention：For overcome the problems, such as in long distance igniter vacation spring cause it is unexpected work, improve and safeguard and safe to use
Property.
Technical solutions of the utility model：A kind of firing lock, including upper connector, striker, lower connector, pull rod, guarantor
Danger pin, spring, the upper connector and lower connector are connected through a screw thread, and inside provides installation space for other parts, external
There are the interfaces being connect with igniter other spare parts；Striker is fixed on connector and lower connection with pull rod by inclined-plane
In vivo；Spring is located between striker and lower connector；The safety plug for playing safety effect is located at striker and the cooperation of lower connector
In hole；Remove safety plug before work, when work, pull rod drives striker to move out, compressed spring, when pull rod and striker
The limiting holes that inclined-plane pulls out lower connector are engaged, the separation of occlusion inclined-plane discharges striker, compressed spring driving striker fortune
It is dynamic, complete percussion function.
Good effect：This firing lock structure is more than you know, solves the problems, such as spring in the vacation of igniter, and does not increase maintenance and make
Workload, securely and reliably.
Description of the drawings
Fig. 1 is the firing lock structural schematic diagram of current long distance igniter.
Fig. 2 is spring schematic diagram in current firing lock vacation.
Fig. 3 is the structural schematic diagram of invention.
Specific implementation mode
This firing lock is described in further detail below by specific implementation mode：
The upper connector 1 of this firing lock and lower connector 3 are connected through a screw thread, internal to provide installation sky for other parts
Between, it is external that there are the interfaces being connect with igniter other spare parts.
Striker 2 is engaged with pull rod 4 by inclined-plane, is fixed in connector 1 and lower connector 3；Spring 6 is located at striker
Between 2 and lower connector 3；Safety plug 5 is located at striker 2 in lower 3 matching hole of connector, plays safety effect, is taken before work
Under.
When work, pull rod 4 drives striker 2 to move out, compressed spring 6.It is engaged inclined-plane when pull rod 4 and striker 2
The limiting holes of lower connector 3 are pulled out, the separation of occlusion inclined-plane discharges striker 2, and compressed spring 6 drives striker 2 to move,
Complete percussion function.
