Description
Technical field
The invention belongs to fuse technical field of security, and in particular to a kind of fuse security mechanism with auto-lock function and draw
Letter.
Background technology
In Fuze Technology field, most common motion has slide block mechanism and isolation rotor mechanism, both fitness machines
Structure is generally and the safety piece such as gunpowder promotional implement, gunpowder pin removal, motor, electromagnetism pin removal combination composition fuse security mechanism.
Existing security mechanism has following defect：
First, mechanism's radial dimension is big, is not suitable for the small occasion of radial dimension requirement.
Secondly, mechanism kinematic does not have lock function afterwards in place, under vibration, easily causes security mechanism dislocation,
The detonation for ultimately resulting in fuse is incomplete.
Again, without the environmental information effectively utilized on bullet, (such as fly above-mentioned security mechanism overload, centrifugal force, Aerodynamic Heating
Deng), the driving of the safety piece such as gunpowder promotional implement, gunpowder pin removal, motor, electromagnetism pin removal needs electricity on consumption fuse or bullet
Source, causes energy dissipation.
The content of the invention
The present invention provides a kind of fuse security mechanism and fuse with auto-lock function, it is intended that using flying

Shell；
During work, the insurance of arming device, when quality bar experiences overload, quality bar and the primer being attached thereto
Defined position is moved to downwardly together with shell, while tile loses support sliding downwards until regaining the middle part of quality bar
Step is supported, so that by quality rod lock in defined position；At defined position, primer is with electric cap and relay powder column just
In to positive status, electric cap) detonation primer, primer detonation relay powder column, relay powder column detonation booster gains.
Further, the spring between the step of the quality bar and lower end is also put in including set.
Further, the also paper washer including being positioned between the quality bar and primer.
Further, the material of the tile is rod iron, and the material of the quality bar is tungsten bar, and preferably the trade mark is W273's
Tungsten bar.
Advantageous Effects of the invention are embodied in：
Usually, securing member makes quality bar be in home position, constitutes the insurance of the security mechanism first order, related to quality bar
Sensitive firer's element (such as detonator or igniter cap) and booster gains in the primer of connection and Explosive sequence is spaced apart, shell
The solid section of lower end is in sensitive firer's element (such as detonator or igniter cap) and booster gains between, it is ensured that fuse is in detonator or fire
Misfire during the accidental preact of cap, so as to avoid ammunition premature burst so that jeopardizing the safety of our personnel and equipment.When fuse is needed
When wanting arming, the manual safety part on quality bar is released first, when motion is experienced flown on bullet overload, matter
Gauge rod and the primer and shell that are attached thereto, overcome the drag of spring to move downward so that in primer and Explosive sequence
Sensitive firer's element (such as detonator or igniter cap) and booster gains are aligned, and now, tile slides under gravity, lock mass bar
In position in place.Innovative point of the invention is, using the structure type of " quality bar+spring+tile ", to be flown using on bullet
Overload arming, and after motion in place, tile lock mass bar, it is ensured that quality rod lock is in position in place.
Further, the spring between the step of the quality bar and lower end is put in present invention additionally comprises set, forms second
Level insurance, when first order securing member is misused, by second level safety effect, effectively prevents from misquoting quick-fried.
Further, the present invention also sets paper washer between the quality bar and primer, and the quantity of paper washer is 1~3,
Ensure that primer is installed to when on quality bar with shell, it is very close to each other between quality bar and primer.
Generally speaking, it is integrated with execution the invention enables driving, locking, it is easy to greatly reduce overall structure size, and
And the present invention overloads arming using trajectory, driven without using fuse or missile power supply, being specially adapted to radial dimension will
Ask small fuse security mechanism field.
