The invention belongs to the field of launch boxes, and discloses a reusable launch box fragile cover, a launch box and a method, the reusable launch box fragile cover comprises a cover frame, a fragile cover body and a pressing plate, the fragile cover body is composed of a plurality of springback
petal bodies, and the springback
petal bodies comprise elastic bodies,
skin and light filler, so that the fragile cover can be opened and folded outwards under the action of external force, and the pressing plate is arranged on the fragile cover body. Meanwhile, the springback
petal bodies can be recovered, so that the fragile cover can be repeatedly used, and the maintenance cost is greatly reduced; in addition, due to the adoption of the design of the springback petal bodies, the damage to operators,
peripheral equipment and the environment caused by splinters generated by opening the cover in a traditional explosion mode is avoided, and the safety is improved. By the adoption of the fragile cover, the problems that an existing fragile cover of the launching box is disposable, maintenance cost is high, and potential safety hazards exist are effectively solved; the fragile cover has the advantages of light weight,
water resistance, dust resistance,
corrosion resistance and the like; and the strength is high, the response is fast, rebounding can be achieved, and an internal
missile can be effectively isolated from the outside when not in use.
