And connection saddle 3-5 is fixed on protected object body, so that whole device is fixed on protected object body, foreboard 2-12 by
To when hitting, the assembly of crumple bar 2-1 and cylinder 1-1 slide backward, and seat board 3-1 is driven backward when cylinder 1-1 is moved backward
Mobile, seat board 3-1 compresses the spring on two spring loop bar 3-2, and spring absorbs impact force, and spring foreshortens to most short
When, elastic buffer seat 3 reaches buffer limit.Seat board 3-1 and middle slide bar 3-6 can be fixed together by thick screw 3-10 so that
Impact force carries out elastic buffer without elastic buffer seat 3, and when thick screw 3-10 is removed, impact force passes through elastic buffer seat 3
Elastic buffer is carried out, can select to install or unload thick screw 3-10 as needed.
Described splitting column I1-6-2 and split the material of column II2-10 is highstrenghtpiston.
A kind of operation principle of rupture formula energy-absorbing collapsing structure of the present invention：When foreboard 2-12 is hit, crumple bar 2-1 and
The assembly of cylinder 1-1 slides backward, and first passes through the buffering of elastic buffer seat 3, after elastic buffer seat 3 reaches buffer limit,
Crumple bar 2-1 and cylinder 1-1 are produced relative sliding, and crumple bar 2-1 enters in cylinder 1-1, and the moving process of crumple bar 2-1 is
Crumple process, crumple can not only be protected to being knocked part, and certain protection can also be carried out to active ram；Due to
The rear end face of bull stick 2-3 two short is closed with the front end annular face paste of cylinder 1-1, bull stick 2-3 two short along articulated position to
Preceding rotation, bull stick 2-3 two short respectively forwardly press long bull stick 2-4, bull stick 2-4 two long also therewith along articulated position forward
Rotation, at this moment two articulated cylinder II2-5 respectively by connecting rod 1-4 drive into rod 1-3 on rod sliding sleeve 1-5 to advancing slip
It is dynamic, be broken after splitting column I1-6-2 and contact into rod sliding sleeve 1-5, it is multiple split column I1-6-2 and be broken progress repeatedly unload power, split mast
1-6 can be dismantled, and be replaced convenient for splitting counterincision mast 1-6 after column I1-6-2 fractures.The effect for splitting the setting of slot 1-6-3 is just
It is broken from the position for splitting slot 1-6-3 in splitting column I1-6-2；When foreboard 2-12 by hitting partially, foreboard 2-12 can be around itself and front bar
The articulated position of 2-13 rotates, and at this moment semicircular ring 2-1 can also be slided in rectangular channel 2-9, and semicircular ring 2-1 also can be in rectangular channel 2-
In 9 when sliding, split after column II2-10 contact with front bar 2-13 and be broken, it is multiple split column II2-10 and be broken progress repeatedly unload power, to inclined
Hit carry out buffering.Screw can be inserted in two circular through holes on connection saddle 3-5, consolidate to which saddle 3-5 will be connected
It is scheduled on protected object body, to which whole device is fixed on protected object body, when foreboard 2-12 is hit, crumple bar 2-
The assembly of 1 and cylinder 1-1 slides backward, and drives seat board 3-1 to move backward when cylinder 1-1 is moved backward, seat board 3-1 compressions two
Spring on a spring loop bar 3-2, spring absorb impact force, and spring foreshortens to most in short-term, and elastic buffer seat 3 reaches slow
Rush the limit.Seat board 3-1 and middle slide bar 3-6 can be fixed together by thick screw 3-10 so that impact force is without elastic buffer
Seat 3 carries out elastic buffer, and when thick screw 3-10 is removed, impact force carries out elastic buffer by elastic buffer seat 3, can basis
Selection is needed to install or unload thick screw 3-10.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, the art
The variations, modifications, additions or substitutions that those of ordinary skill is made in the essential scope of the present invention also belong to the guarantor of the present invention
Protect range.
