When the top cover 1 is opened, the magic tape connecting side of the top cover 1 is directly opened, as shown in fig. 2 and 3.

The internal structure of the top cover 1 is shown in fig. 4, and the top cover 1 comprises a top cover shell, a fire extinguishing agent 6 and a gas generating agent 5 which are arranged inside the top cover 1; wherein top cap casing and 2 top openings of staving match have the disc structure of certain thickness, include: a fragile layer 9, a top cover fireproof layer 7, a combustible layer 10 and a support plate 8; the innermost layer is a fragile layer 9, the inner cavity of the fragile layer 9 is used for containing the fire extinguishing agent 6, and the gas generating agent 5 is positioned in the center of the inner part of the fragile layer 9; the end of the top cover 1 opposite to the barrel body 2 is the lower end of the top cover, and the other end of the top cover is the upper end of the top cover; the top cover fireproof layer 7 is arranged outside the fragile layer 9, the lower end of the top cover fireproof layer 7 is opened, namely the lower end of the fragile layer 9 is not wrapped, and the combustible layer 10 is arranged at the lower end of the fragile packaging material layer 9; and a support plate 8 is arranged between the upper end of the fragile layer 9 and the fireproof layer 7 of the top cover. The gas generating agent 5 located centrally inside the frangible layer 9 is connected to the triggering means 4 disposed within the combustible layer 10.

In the above, the gas generating agent 5 is gunpowder, and the trigger device 4 is gunpowder fuse, and can be a target breaking trigger or gunpowder combustion trigger; the fire extinguishing agent 6 adopts foam extinguishing agent; breakable layer 9 adopts polyurethane foam, and top cap flame retardant coating 7 adopts fire prevention oxford, easily fires layer 10 and adopts the cotton, and backup pad 8 adopts the PC board.

As shown in FIG. 5, the barrel body 2 is of a multi-layer structure and sequentially comprises a barrel body fire-proof layer 11, a heat insulation layer 12, a fixed ring layer 13, an inner bulletproof layer 14 and an outer bulletproof layer 15 from inside to outside. Wherein each layer is characterized in that:

the barrel body fireproof layer 11 is made of materials such as glass fiber and ceramic fiber and is used for preventing flame in the explosion process from influencing the bulletproof performance of the explosion-proof barrel; the heat insulation layer 12 is made of materials such as aramid fiber and the like and is used for isolating the influence of high temperature of flame on the elasticity prevention performance of the explosion-proof barrel; the fixed ring layer 13 is made of PC or sprayed foam polyurethane and the like and is used for supporting the main body structure of the barrel body 2; the inner bulletproof layer 14 is bulletproof fiber, such as PE or aramid fiber; the outer bulletproof layer 15 is bulletproof fiber, such as PE or aramid fiber.

And finally, arranging an outer sleeve made of fireproof materials (such as oxford) as an outer package on the outermost part of the barrel body 2 of the explosion-proof barrel.

Because the explosive has powerful impact force in the moment of explosion, in order to prevent fragments from flying out from the barrel bottom, the connection strength between the barrel bottom 3 and the barrel body 2 needs to be ensured. The existing technology has large processing difficulty for the barrel structure with the barrel bottom, needs to process through a die, and is easy to break at the place where the barrel bottom is connected with the barrel body. Based on this, connect through the meshbelt group between bottom of a barrel 3 and staving 2, this kind of structural style's meshbelt group can be with the firm connection between staving 2 and bottom of a barrel 3, prevents that the fragmentation from the bottom of a barrel departure when the explosion.

The portion of the webbing 21 between the inner 14 and outer 15 ballistic layers is secured to the inner 14 and outer 15 ballistic layers by stitching or by gluing and the portion of the webbing on the outer surface of the outer layer 15 is secured to the outer layer 15 by stitching or by gluing.

When the explosion-proof barrel is used, if the explosive is gasoline combustion substances, flame and fragments are generated during explosion, the flame ignites a powder fuse (namely the trigger device 4) in the combustible layer 10 of the top cover 1, and the powder fuse further ignites the gas generating agent 5. Gas generating agent 5 produces a large amount of gases, struts polyurethane foam (breakable layer 9 promptly), because backup pad 8 is the PC panel, has certain toughness and intensity, can not be broken, and fire extinguishing agent 6 can not be shed to the top, can only shed in the bucket, realizes the function of putting out a fire. If the explosive is gunpowder, certain shock waves are generated during explosion to shatter the polyurethane foam (namely the fragile layer 9), and the fire extinguishing agent 6 in the top cover 1 can be thrown into the barrel at the same time.

In summary, the above is merely a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
