Description
Technical field
This utility model belongs to space technology field, is specifically related to a kind of buffer metal shell fragment.
Background technology
For utilizing metal to absorb or the metal buffer material of dissipation energy in plastic deformation or during being cut, it is ensured that bigger
Power output, volume and the quality of needs are the biggest, are mainly used in the seat context buffer of manned spacecraft, present stage root
According to real work and finding, the metal material of 0.2mm had not been used as buffer unit.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of buffer metal shell fragment, and simple in construction is small and exquisite, and carries locking arranging
Execute, there is the deformation controllable feature of energy-absorbing.
This utility model is achieved through the following technical solutions:
A kind of buffer metal shell fragment, including: metal clips body, locking auricle and trip bolt；
Described metal clips body is provided with strip projected parts parallel to each other, and described strip projected parts is Concha Arcae；Locking auricle is positioned at gold
Belong between two adjacent Concha Arcaes of elastic sheet body, after two trip bolts pass locking auricle and metal clips body, by metal elastic
Sheet body is fixed in the plane of external contact part.
Further, it is 2mm～2.5mm that the Concha Arcae of described metal clips body protrudes the height of metal clips body, metal clips
The thickness of body is 0.2mm～0.3mm.
Further, the Concha Arcae of described metal clips body is 0～0.3mm in the deformation stroke of deformation process medium wave peak height, inhales
Receive the energy of 0～500N deformation force.
Beneficial effect: (1) this utility model occurs elastic deformation by the Concha Arcae of buffer metal shell fragment under the effect by power,
Cross absorption energy in elastic deformation process, reach the effect of buffering energy-absorbing, and by regulating quantity and the height of Concha Arcae crest of Concha Arcae
Degree, realizes controlled Concha Arcae deflection and then obtains relatively accurate buffering capacity deflection, reaching buffering energy-absorbing and be adjustably controlled
Purpose.
(2) this utility model is by locking auricle and the locking measure of trip bolt, is adapted in rocket transport and flight course
Mechanical environment.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model.
Fig. 2 is front view of the present utility model.
Wherein, the locking auricle of 1-, 2-trip bolt, 3-metal clips body.
Detailed description of the invention
Develop simultaneously embodiment below in conjunction with the accompanying drawings, is described in detail this utility model.
This utility model provides a kind of buffer metal shell fragment, sees accompanying drawing 1,2, including: metal clips body 3, anti-Auricularia
Sheet 1 and trip bolt 2；
Described metal clips body 3 is provided with strip projected parts parallel to each other, and described strip projected parts is Concha Arcae, and Concha Arcae protrudes metal
The height of elastic sheet body 3 is 2.5mm, and the height being Concha Arcae crest is 2.5mm, and the thickness of metal clips body 3 is 0.2mm,
The number of Concha Arcae is 4～6；
Locking auricle 1 is between 3 two adjacent Concha Arcaes of metal clips body, and two trip bolts 2 are through locking auricle 1
And after metal clips body 3, metal clips body 3 is fixed in the plane of external contact part, wherein, locking auricle 1
It is prevented from metal clips body 3 to occur to loosen and rotate；
When exerting a force metal clips body 3, the Concha Arcae of metal clips body 3 is first subjected to extruding force and carries out elastic deformation, watt
Stupefied expand to its both sides when carrying out elastic deformation, make the height of Concha Arcae crest reduce；The elemental height of Concha Arcae crest is 2.5mm,
Be squeezed deformation time, Concha Arcae crest height buffer deformation 0.1mm time, absorb deformation force about 15N, the height of Concha Arcae crest
During buffering deformation 0.2mm, absorb deformation force about 28N, when the height buffer of Concha Arcae crest deforms 0.3mm, absorb deformation force about
60N, the Concha Arcae of metal clips body 3 impulse stroke in deformation process is 0～0.3mm, it is possible to absorb 0～500N deformation
The energy of power, plays the effect of deformation energy-absorbing, and then plays the effect of buffering, and by the quantity of regulation Concha Arcae and Concha Arcae crest
Height, realize controlled Concha Arcae deflection and then obtain relatively accurate buffering capacity deflection so that metal clips body 3
Buffering capacity can control.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection model of the present utility model
Enclose.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in
Within protection domain of the present utility model.
