Description
Technical field
The present invention relates to watch box harness field, more particularly to a kind of flak jackets.
Background technology
Flak jackets（Bulletproof Vest）, for protecting the injury of bullet or shell fragment to human body, it is developed so far, is combined
The flak jackets of formula is widely used, i.e., using Lightweight ceramic ceramics as outer layer, and Kevlar etc. is high, and performance fabric is used as internal layer.It is soft
The shellproof internal layer of matter such as individual layer laminated cloth overlapping after can as soft body armor trunk structure, multilayer compacting then can turn into be used for
The hard ballistic materials such as shellproof reinforcement plate, most of body energy is at the fiber near shock point or shock point, to pass through
Excessive tensile or puncture make fibrous fracture and absorbed；And the fracture of fiber hardly occurs in needling non-woven felt, pin
Non-woven felt is made up of a large amount of short fibres, in the absence of intertwined point, almost the fixation point reflection without strain wave.Its bulletproof effect takes
Diffusion velocity that certainly can be in felt in bullet impact.Hard ballistic outer layer then hit by body after its depression and rupture absorb
The impact energy of body.Although the scheme of " using both hard and soft tactics " largely improves the bulletproof effect of flak jackets really, merely
One layer of hard ballistic layer plus its bulletproof effect of the flak jackets of one layer of soft ballistic layer it is still inadequate.
The content of the invention
Present invention mainly solves technical problem be it is new far above thickness flak jackets of the same race there is provided a kind of bulletproof ability
Type flak jackets.
The technical solution adopted for the present invention to solve the technical problems is：Flak jackets, including at least two layers bulletproof composite layer,
The bulletproof composite layer is made up of the hard ballistic layer and soft ballistic layer along ballistic path direction ecto-entad；Bulletproof composite layer is provided with
Two layers, respectively the first bulletproof composite layer and the second bulletproof composite layer, the first bulletproof composite layer is by the first hard ballistic layer and the
One soft ballistic layer is constituted, and the second bulletproof composite layer is made up of the second hard ballistic layer and the second soft ballistic layer, the first hard
Burster course is constituted from several to against the raised hard sheet of ballistic path direction, and the second hard ballistic layer is not by having the hard of radian
Sheet material is constituted from several to against the raised hard sheet of ballistic path direction；First hard ballistic layer and the second hard ballistic layer
Thickness it is identical, be 9.8mm ~ 18mm；First soft ballistic layer and the second soft ballistic layer use needling non-woven felt, and thickness is
15~20mm；The hard sheet is alumina plate, alloy aluminium sheet, boron carbide ceramics plate, carborundum plate, glass epoxy or ceramics
Composite plate；It is articulated and connected between neighbouring hard sheet；One side per a piece of hard sheet is provided with and hard sheet one
Bearing pin and the pin cylinder of shaping, the another side of hard sheet ride over close to horizontal hard sheet on, exceed in transverse direction close to horizontal stroke
To bearing pin and the pin cylinder of hard sheet, bearing pin and pin cylinder are coaxially disposed, and it is pin cylinder that bearing pin, which exceedes the length of hard sheet longitudinal direction,
Depth；Hard sheet per a piece of hard sheet with arrangement above its longitudinal direction is hinged by bearing pin and pin cylinder, and being provided with pin cylinder makes
Hard sheet be closely buckled in its close to horizontal hard sheet torsion spring；The hard sheet is sandwiched between the wire of transverse and longitudinal braiding
Net；On the surface of the hard sheet at pin axle pin cylinder provided be fixedly connected on hard sheet block close to transverse direction
The iron plate of hard sheet, the length of iron plate is less than the size of hard sheet longitudinal direction；The iron plate welding is bonded in hard sheet
On.By common one layer of bulletproof composite layer（I.e. hard ballistic layer and soft ballistic layer）Become two layers it is even more many, formed it is multiple
The circulation of body energy absorption, depression and rupture after being hit by multiple hard ballistic outer layer by body, missile spin friction
Heat and shock occur the sound and absorbed after the impact energy of body and the energy-absorbing of soft ballistic layer, and bulletproof ability is strengthened.The
One bulletproof composite layer and the second bulletproof composite layer can use the structure of the soft or hard layer of general flak jackets, first after such as sewing shaping
The second hard ballistic layer is inserted between soft ballistic layer and the second soft ballistic layer, it is soft that the first hard ballistic layer is then inserted in first
Between burster course and clothes outermost layer；The settable multilayer of bulletproof composite layer, but it is suitable with common flak jackets thickness in order to ensure, adopt
Set optimal with two layers, simply can be understood as original one layer of hard ballistic layer being divided into two layers, original soft ballistic
Layer is divided into two layers, then hard soft or hard soft setting, although each layer of hard ballistic layer, each layer of soft ballistic layer are all only original
Hard ballistic layer, soft ballistic layer half it is thick, but the energy-absorbing function of soft or hard different burster courses is dispersed into twice, than identical
The bulletproof ability of the bulletproof composite layer of thickness is greatly improved.Each more than III ballistic protection level of same thickness nominal mass rank
Flak jackets use this setting after almost improve nearly one rank.Hard sheet is outwardly to clear up the impact of body
Potential energy, to increase this effect, the second hard ballistic layer of internal layer can also use outwardly structure, if considering processing
Convenience, internal layer also can be using the tabular for not having radian.The hard ballistic layer that hard sheet can generally be used using flak jackets
Multiple material, preferably elasticity, the material of good toughness, so body hit evagination hard ballistic layer when can also make hard piece
The energy of material indent, further buffering body.During ballisticimpact, it is very that component can be moved freely relative to other components
Useful, in soft bullet-resistant garment industry, in order to which component integrally to be loaded to the certain continuity of vest Bao Shiwei components offer simultaneously
Prevent component disconnected from each other, frequently with tailor-tacking technology.The present invention also does such set on hard ballistic layer and caused in body
Moving freely between generation hard sheet, the i.e. initial stage in elastomer contact flak jackets when rigid connection touches outermost layer hard ballistic layer
Just the energy of a large amount of buffering bodies, further enhances the bulletproof ability of flak jackets.Hard sheet is square for outwardly convex, its
One side of longitudinal direction is provided with pin axle pin cylinder, can regard coaxial pin axle pin cylinder as and be each attached on longitudinal one side；More than hard sheet
The bearing pin of the length thereof of longitudinal direction is inserted in pin cylinder, due to the hard piece on all longitudinal directions of deadweight of hard sheet on longitudinal direction
Material close to（Between i.e. adjacent hard sheet up and down in bearing pin insertion pin cylinder）, when a certain piece of hard sheet is by ballistic impact with
Its bearing pin rotates for axle；The longitudinal edge of hard sheet one is coaxial pin axle pin cylinder, and another longitudinal edge is then because the effect of torsion spring is tight
Detain and slightly above the hard sheet on side, this ensure that the moment hard sheet in ballistic impact can be rotated along bearing pin, realize
Buffer the effect of ballistic impact potential energy.For the free degree for the rotation that hard sheet is better achieved, the soft ballistic layer at its rear
Using tailor-tacking technology.Iron plate is blocked by possessing that torsion spring is acted on approximately perpendicular to hard sheet by the iron plate extended perpendicularly out
The adjacent hard sheet rotated to iron plate, the hard sheet of the width of iron plate beside not jack-up is defined, i.e., iron plate is in two
In the intersecting circular arc of hard sheet formation, iron plate uses the iron plate of common material, and hard sheet is with pin so in ballistic impact
Axle is that axle is rotated, and because intensity, the toughness of hard sheet are above iron plate, iron plate is broken in the rotation of hard sheet, also one
Partly play a part of absorbing ballistic impact energy, the usually presence of iron plate is then prevented due to the adjacent hard piece of the effect of torsion spring
Material is separated from and leaves gap, become flak jackets part only have soft ballistic layer and without hard ballistic layer situation.Iron plate is excellent
Elect as and be bonded on hard sheet, it is ensured that iron plate is continuous under ordinary loading conditions, and then disconnected when by ballistic impact de-
From hard sheet.The setting of woven wire does not increase hard ballistic layer how much weight, but takes full advantage of soft ballistic layer
Shellproof principle（Kinetic energy is absorbed in draw-texture process of the high-strength high-modulus fibre under missile impact, high-strength high-modulus fibre
The non-through at the power consumption of fracture, overall deformation of the fabric laminate near point of impact, including attack point back is raised and absorbs
Body energy etc.）So that hard ballistic layer has also used for reference the bulletproof ability of soft ballistic layer, strengthens the anti-resilience energy of flak jackets
Power.First hard ballistic layer is identical with the thickness of the second hard ballistic layer, is 9.8mm ~ 18mm.Ordinary rigid is so essentially to prevent
The thickness of bullet layer half, hard ballistic layer of the integral thickness also with common flak jackets（That is outer layer）Thickness is suitable, bulletproof ability
But greatly improve.First soft ballistic layer and the second soft ballistic layer use needling non-woven felt, and thickness is 15 ~ 20mm.So
The essentially thickness of ordinary soft burster course half, soft ballistic layer of the integral thickness also with common flak jackets（That is internal layer）It is thick
Degree is suitable, and bulletproof ability is but greatly improved.
It is many that bulletproof composite layer is set to hard ballistic layer, soft ballistic layer by the present invention in the case where integral thickness is constant
The mode that layer is continuously set, strengthens the absorption to body energy and buffering, and bulletproof effect is more preferable；Hard sheet is outwardly to disappear
Solve the impact potential energy of body；It is hinged between hard sheet so that occurring hard piece when body rigid connection touches outermost layer hard ballistic layer
Moving freely between material, the i.e. energy for just largely buffering bodies initial stage in elastomer contact flak jackets, the anti-resilience energy of flak jackets
Power is greatly reinforced；Woven wire is set in hard ballistic layer, the bullet-proof mechanism of soft ballistic layer has been used for reference, bulletproof ability is stronger.
