The outer cover of the barrel bottom bulletproof layer 19 is provided with a cloth bag 17, the cloth bag 17 upwards bypasses the top of the barrel body 2 and then downwards extends along the barrel body 2 to wrap the outer bulletproof layer 15 of the barrel body 2, the structure of the cloth bag 17 is shown in fig. 7, and the surface of the cloth bag 17 is sprayed with super-elastic materials, so that the structure is not disassembled even if large deformation occurs, and the bulletproof performance is enhanced. Finally, an outer sleeve made of fireproof materials (such as oxford) is arranged at the outermost part of the explosion-proof barrel body 2 to serve as an outer sleeve.
Since the explosive has strong impact force at the moment of explosion, in order to prevent the broken piece 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 prior art has great processing difficulty on the barrel structure with the barrel bottom, needs to be processed by opening a die, and is easy to break at the connection place of the barrel bottom and the barrel body. Based on this, connect through the meshbelt group between barrel head 3 and staving 2, the meshbelt group of this kind of structural style can be with firmly being connected between staving 2 and the barrel head 3, prevents that the broken piece from flying out from the barrel head when exploding.

The part of the webbing 21 between the inner and outer ballistic layers 14, 15 is secured to the inner and outer ballistic layers 14, 15 by stitching or gluing and the part of the webbing on the outer surface of the outer ballistic layer 15 is secured to the outer ballistic layer 15 by stitching or gluing.
When the explosion-proof barrel is used, if the explosive is a gasoline combustion substance, flame and fragments are generated during explosion, the flame ignites a gunpowder fuse (namely a triggering device 4) in the inflammable layer 10 of the top cover 1, and the gunpowder fuse further ignites the gas generating agent 5. The gas generating agent 5 generates a large amount of gas, and the polyurethane foam (namely the fragile layer 9) is spread, so that the support plate 8 is a PC plate, has certain toughness and strength, cannot be broken, and the fire extinguishing agent 6 cannot be thrown to the top and can only be thrown into a barrel, thereby realizing the fire extinguishing function. If the explosive is gunpowder, a certain shock wave is generated during explosion, polyurethane foam (namely the fragile layer 9) is crushed, and the fire extinguishing agent 6 in the top cover 1 is thrown into the barrel at the same time.
In summary, the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
