Description
Technical field
The invention belongs to fuze safety mechanism technical fields, and in particular to a kind of gunpowder constraint formula isolation machine based on inertia
Structure.
Background technique
Priming system is equipped with gunpowder or explosive, burning or explosion is generated after by environmental stimuli, with the gunpowder that ignites, ignition charge
Or do the general name of the disposable component and device of mechanical work.It is usually provided with interrupter in priming system, makees
With being that sensitive firer's element in Explosive sequence is isolated usually with next stage firer's element, guarantee that fuse is accidental in its priming system
Misfire when preact, to avoid ammunition premature burst so that jeopardizing the safety of personnel and equipment.
The safety of fuse be related to the demonstration of fuse, design, manufacture, inspection and acceptance, test, duties processing, using and
The life cycle managements such as explosive disposal.In safety period life-cycle of fuse, the effect of interrupter is to guarantee fuse right
It is in arm-to-arm in effective short-term/space of interacting goals, is safe condition in the case of remaining.
Currently, common interrupter mechanism has slide block mechanism, lever type mechanisms and isolation rotor mechanism, wherein being turned with level
Minor interrupter is relatively conventional.Under normal conditions, horizontal rotor formula interrupter utilizes torsion spring, clockwork spring (disc spring) or other
Motive power of the spring as mechanism kinematic has lesser axial dimension, is adapted to the small occasion of axial dimension requirement, and horizontal
There is rotator type interrupter biggish releasing corner is isolated, and can ensure that flame proof safety under normal circumstances.But it is existing
Horizontal rotor formula interrupter also suffers from certain drawbacks, and defect is mainly concentrated as following several points.Firstly, when interrupter is protected
After danger releases and moves in place, interrupter does not have lock function and be easy to cause interrupter to misplace under vibration,
Explosive train is eventually led to just not exclusively；Secondly, the two-stage safety piece Heterogeneous Permutation of horizontal rotor formula interrupter, can make
Mechanism size is larger, unreasonable to space utilization；Again, horizontal rotor formula interrupter usually not efficiently uses the ring on bullet
Border information (such as flight overload, centrifugal force, Aerodynamic Heating), and the driving of two-stage safety piece needs to consume fuse or missile power supply,
Energy dissipation is caused, and safety is lower.Drawbacks described above is subject to certain restrictions the application of horizontal rotor formula interrupter,
It has a certain impact to the safety and practicability of interrupter, is unable to fully meet the safe handling of fuse.
Summary of the invention
Aiming at the above defects or improvement requirements of the prior art, the present invention provides a kind of, and the gunpowder based on inertia constrains formula
Interrupter, wherein being provided with biggish releasing isolation corner by using the setting that two-stage is insured, it is ensured that flame proof peace usually
Quan Xing, and interrupter has lock function after movement in place, can ensure that under vibration in state in place, guarantees detonation
Reliability, promote safety and the practicability of fuze mechanism.
To achieve the above object, according to one aspect of the present invention, a kind of gunpowder constraint formula isolation based on inertia is provided
Mechanism, including center be provided in the ontology and coaxial sleeve insertion rotor hole of rotor hole can opposing body's rotation rotor, it is special

The pin hole of state；
During being converted to arm-to-arm under rotor is driven from safe condition, the inertial elements component is driven
And from being detached from the third blind hole and being placed in the inertial elements component integrally in first blind hole, correspondingly,
The latch ends of the gunpowder pin removal are driven to be detached from from the pin hole, and then the rotor can be rotated centainly by driving
Angle, so that the accommodating hole for passing fiery component and the detonation transmission part is being to just, and first blind hole and the pin hole pair
It is embedded in one end of the inertial elements component in the pin hole to lock the arm-to-arm, to can realize from peace
Total state is transformed into the arm-to-arm and locks the arm-to-arm.
As a further improvement of the present invention, arc groove is offered on the rotor, for leading for rotor rotation direction
To and limit the rotational angle of rotor.
As a further improvement of the present invention, on cross section the arc groove both ends and rotor hole center line institute
The angle that the angle of composition need to rotate when being converted to arm-to-arm from safe condition with rotor is identical.
As a further improvement of the present invention, on cross section the arc groove both ends and rotor hole center line institute
The angle of composition is 75 °~135 °.
As a further improvement of the present invention, it is also provided on the end face that rotor corresponds to ontology for accommodating locking member
The 4th blind hole correspondingly, corresponding ball pin hole is offered on the ontology for accommodating locking member；
The locking member includes Lock spring and ball pin, and the Lock spring is in contraction state in the secure state,
The ball pin end is contacted with the rotor hole end surface of the ontology, when rotor turns to arm-to-arm from safe condition, described
Four blind holes are just with the ball pin hole to just, i.e., the Lock spring compressive state of the described locking member releases, described in ball pin insertion
To lock the arm-to-arm in ball pin hole.
As a further improvement of the present invention, the inertial elements component includes inertia cylinder and inertial spring, the inertia
One end of cylinder offers the groove for fixing described inertial spring one end；
In the secure state, the inertia cylinder is placed in the third blind hole on one side end face of rotor, described
The other end of inertial spring is placed in first blind hole on the ontology；The rotor turns to pending from safe condition
In state procedure, the inertial spring is in compressive state and the inertial elements component is integrally embedded in first blind hole；
When the rotor turns to arm-to-arm, the pin hole on first blind hole and the rotor is to just, the inertia cylinder
It is embedded in the pin hole to lock the arm-to-arm.
