The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and operation principle are described in more detail.
As shown in Figure 1; A kind of gradient type sandwich of the present invention anti-explosion tank; Comprise cover plate relief hole 1, cover plate 2, backing 3, inner core 4, interior cushion 5, middle cushion 6, outer cushion 7, buffer plate 8, urceolus 9, urceolus relief hole 10, reinforcement 11 and castor 12; Cover plate 2 is formed top cover and on cover plate 2, is had cover plate relief hole 1 with buffering liner plate 3; Inner core 4, interior cushion 5, middle cushion 6, outer cushion 7 and urceolus 9 are formed tank bodies and also on urceolus 9 base plates, are had urceolus relief hole 10, and the material of interior cushion 5, middle cushion 6 and outer cushion 7 is that closed-cell foam gold and its density reduce formation gradient laminboard layer from inside to outside successively, and the bottom of urceolus 9 base plates is connected with at least two reinforcements 11; Two ends, urceolus 9 base plate bottom are provided with castor 12; Buffer plate 8 is arranged between the inboard of top and inner core 4 of urceolus 9 base plates, and the thickness of buffer plate 8 is greater than the thickness of backing 3, and the thickness of urceolus 9 is greater than the thickness of inner core 4; Cover plate 2 adopts screw to be connected with buffering liner plate 3, and buffer plate 8 adopts screw to be connected with urceolus 9.
As shown in Figure 2, inner core 4, interior cushion 5, middle cushion 6, outer cushion 7 and urceolus 9 are formed tank body, and buffer plate 8 is arranged on the inboard of inner core 4.
