Abstract
The invention provides a detonator security mechanism with a self-locking function. The detonator security mechanism comprises a sleeve, a plurality of tiles, a mass rod, detonating powder, a tube shell and a safety mechanism, wherein a step is arranged on the middle part of the mass rod; the sleeve is arranged on the part above the step of the mass rod; the tiles are uniformly distributed on the circumference in the sleeve; the safety mechanism is mounted at the upper end of the mass rod; the detonating powder is connected with the lower end of the mass rod; the tube shell is arranged outside the detonating powder. In a working process, the insurance of the safety mechanism is relieved, and when the mass rod senses overload, the mass rod downward moves to a limited position together with the detonating powder and the tube shell connected with the mass rod, and meanwhile, the tiles lose support and downward fall till reacquiring support from the middle step of the mass rod, so that the mass rod is locked on the limited position. The invention also provides a detonator based on the detonator security mechanism. The detonator security mechanism provided by the invention utilizes flight overload to drive the security mechanism and requires no detonator or flipping power supply for driving, has the self-locking function and high reliability, and is compact in structure and fit for a detonator use occasion with small radial size requirement.
Description
Technical field
The invention belongs to fuse technical field of security, be specifically related to a kind of fuse security mechanism with auto-lock function and fuse.
Background technology
In Fuze Technology field, modal motion has slide block mechanism and isolation rotor mechanism, and both motions are generally and the safety piece combination composition fuse security mechanism such as gunpowder promotional implement, gunpowder pin removal, motor, electromagnetism pin removal.
Existing security mechanism has following defect:
First, mechanism's radial dimension is big, is not suitable for the occasion that radial dimension requirement is little.
Secondly, mechanism kinematic does not have lock function after putting in place, under vibration, it is easy to cause security mechanism to misplace, and ultimately results in detonating not exclusively of fuse.
Again; above-mentioned security mechanism does not effectively utilize the environmental information (such as flight overload, centrifugal force, Aerodynamic Heating etc.) on bullet; the driving of the safety pieces such as gunpowder promotional implement, gunpowder pin removal, motor, electromagnetism pin removal needs to consume fuse or missile power supply, causes energy dissipation.
Summary of the invention
The present invention provides a kind of fuse security mechanism with auto-lock function and fuse, it is intended that utilize flight overload to drive security mechanism, it is not necessary to utilize fuse or missile power supply to drive；Having auto-lock function, reliability is high；Compact conformation, it is adaptable to radial dimension requires little fuse use occasion.
A kind of fuse security mechanism with auto-lock function, including sleeve, tile, quality bar, primer, shell and insurance institution；The middle part of quality bar has step, and the step above section of quality bar is equipped with sleeve, and sleeve inner is evenly distributed with polylith tile along quality bar circumference, the upper end installation insurance mechanism of quality bar, and the lower end of quality bar connects primer, and the outside of primer is equipped with shell；During work, the insurance of arming device, when overload experienced by quality bar, quality bar and the primer being attached thereto and shell move to restriction position downwardly together, tile loses and supports downward landing until the middle bench regaining quality bar supports simultaneously, thus quality rod lock is being limited position.
A kind of fuse with auto-lock function; including body and be installed on intrinsic electric cap, relay powder column, booster gains and fuse security mechanism; holding spacing between described electric cap and described relay powder column, described fuse security mechanism is between described electric cap and described relay powder column；
Described fuse security mechanism includes sleeve, tile, quality bar, primer, shell and insurance institution；The middle part of quality bar has step, the step above section of quality bar is equipped with sleeve, and sleeve inner is evenly distributed with polylith tile along quality bar circumference, the upper end installation insurance mechanism of described quality bar, the lower end of described quality bar connects primer, and the outside of primer is equipped with shell；
During work, the insurance of arming device, when overload experienced by quality bar, quality bar and the primer being attached thereto and shell move to restriction position downwardly together, tile loses and supports downward landing until the middle bench regaining quality bar supports simultaneously, thus quality rod lock is being limited position；It is exactly in positive status, electric cap limiting position, primer and electric cap and relay powder column) detonate primer, and primer detonates relay powder column, and relay powder column detonates booster gains.
Further, also include overlapping the spring between the step and the lower end that are put in described quality bar.
Further, the paper washer being positioned between described quality bar and primer is also included.
Further, the material of described tile is rod iron, and the material of described quality bar is tungsten bar, it is preferable that the trade mark is the tungsten bar of W273.
The Advantageous Effects of the present invention is embodied in:
At ordinary times; securing member makes quality bar be in home position; constitute the insurance of the security mechanism first order; the primer being associated with quality bar is spaced apart with the sensitive firer's element (such as detonator or igniter cap) in Explosive sequence and booster gains; the solid section of shell lower end is between sensitive firer's element (such as detonator or igniter cap) and booster gains; ensure that fuse is misfired when the accidental preact of detonator or igniter cap, thus avoiding ammunition premature burst so that jeopardizing the safety of our personnel and equipment.When fuse needs arming, first the manual safety parts on quality bar are released, when motion experiences flight overload on bullet, quality bar and the primer being attached thereto and shell, the drag overcoming spring moves downward so that primer aligns with the sensitive firer's element (such as detonator or igniter cap) in Explosive sequence and booster gains, now, tile is landing under gravity, and lock mass bar is in the position that puts in place.The innovative point of the present invention is in that to adopt the version of " quality bar+spring+tile ", utilizing on bullet flight overload arming, and after moving and putting in place, tile lock mass bar, it is ensured that quality rod lock is in the position that puts in place.
Further, present invention additionally comprises the spring that set is put between step and the lower end of described quality bar, form second level insurance, when first order securing member is misused, by second level safety effect, effectively prevent from misquoting quick-fried.
Further, the present invention also arranges paper washer between described quality bar and primer, and the quantity of paper washer is 1～3, it is ensured that when primer and shell are installed on quality bar, very close to each other between quality bar and primer.
Generally speaking; the invention enables driving, locking and perform integrated, it is simple to being greatly reduced overall structure size, and the present invention utilizes trajectory overload arming; drive without using fuse or missile power supply, be specially adapted to the fuse security mechanism field that radial dimension requirement is little.
