Abstract
The invention belongs to aviation lifesaving field, is related to a kind of firing lock for ejector seat.Including upper connector, striker, lower connecting rod, pull bar, safety plug, spring, the upper connector and lower connector are connected through a screw thread, and inside provides installing space for other parts, outside to leave the interface being connected with igniter other spare parts；Striker is fixed in connector and lower connector with pull bar by inclined-plane；Spring is located between striker and lower connector；The safety plug for playing safety effect is located in striker and lower connector mating holes；Remove safety plug before work, during work, pull bar drives striker to move out, compression spring, when pull bar and the limiting holes for being engaged inclined-plane and pulling out lower connector of striker, the separation of occlusion inclined-plane, striker is discharged, the Spring driving striker motion compressed, completes percussion function.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 invention 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 released energy after compression spring
Striker, the form that striker steel ball lock is fixed, structure referring to Fig. 1, mainly include connector 7, housing 8, striker body 9, striker 11,
Safety plug 5, spring 6, there is steel ball 10 on striker body 9；Housing 8 is cylinder revolution, and inside has large and small two anchor rings striker 11 left
There is annular groove at end, and the annular groove of big inner ring surface and striker 11 that steel ball 10 passes through housing 8 fixes striker 11 and striker body.
During work, safety plug 5, striker 11 and the lateral movement to the right of striker body 9, compression spring 6, when steel ball ball 10 departs from housing 8 are pulled up
Big anchor ring, striker body 9 release with the fixation of striker 11, to left movement under the driving of spring 6, complete percussion function.
Its shortcoming is referring to Fig. 2：Firing lock needs first to carry out spring before not working, spring in vacation be present, and striker body 9 is unreliable solid
It is fixed, safety plug 5 is pulled up, striker body 9 just can move the possibility for causing surprisingly to work, influence the security safeguarded and used.
The content of the invention
Goal of the invention：To overcome the false upper spring of long distance igniter to cause unexpected the problem of working, improve and safeguard and safe to use
Property.
Technical solution of the present invention：A kind of firing lock, including upper connector 1, striker 2, lower connecting rod 3, pull bar 4, guarantor
Dangerous pin 5, spring 6, the upper connector 1 and lower connector 3 are connected through a screw thread, and inside provides installing space for other parts,
Leave the interface being connected with igniter other spare parts in outside；Striker 2 is fixed on connector 1 with pull bar 4 by inclined-plane
In lower connector 3；Spring 6 is located between striker 2 and lower connector 3；The safety plug 5 for playing safety effect is located at striker 2
In the lower mating holes of connector 3；Remove safety plug 5 before work, during work, pull bar 4 drives striker 2 to move out, and compresses bullet
Spring 6, when pull bar 4 and the limiting holes for being engaged inclined-plane and pulling out lower connector 3 of striker 2, the separation of occlusion inclined-plane, striker 2 is discharged,
The spring 6 compressed drives striker 2 to move, and completes 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.
Brief description of the drawings
Fig. 1 is the firing lock structural representation of current long distance igniter.
Fig. 2 is the false upper spring schematic diagram of current firing lock.
Fig. 3 is the structural representation of invention.
Embodiment
This firing lock is described in further detail below by embodiment：
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, the interface being connected with igniter other spare parts is left in outside.
Striker 2 is engaged with pull bar 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 with the lower mating holes of connector 3, playing safety effect, being removed before work.
During work, pull bar 4 drives striker 2 to move out, compression spring 6.Inclined-plane is engaged when pull bar 4 and striker 2
The limiting holes of lower connector 3 are pulled out, the separation of occlusion inclined-plane, discharge striker 2, the spring 6 compressed drives striker 2 to move,
Complete percussion function.
