Abstract
The invention discloses a bullet bottom fuze and bullet body connecting structure for eliminating a loading bottom gap, which comprises a bullet body, an explosive loading, a pressing screw, a bullet bottom fuze, a paper gasket and a gasket. The compression screw is added between the explosive charge and the primer, and the axial positioning of the explosive charge is ensured by screwing the compression screw. The press screw is contacted with the explosive charge through the pressed paper gasket, so that potential safety hazards caused by bottom gaps are eliminated. During launching, the compression screw directly bears the recoil generated by explosive loading, so that the recoil is prevented from being transmitted to the bottom fuse, and the launching strength of the bottom fuse is ensured more easily. The bottom detonator detonating tube adopts an energy-gathering output structure, so that the detonating capability of the detonating tube is enhanced. A blind hole with a certain depth is arranged at the center of the pressure screw close to the bullet bottom fuze end, so that the pressure screw is ensured not to influence the jet flow formed by the energy-gathering detonating tube to reliably detonate the warhead charge while the emission intensity of the pressure screw is ensured. And a sealing gasket is additionally arranged between the lower end surface of the press screw and the bullet bottom fuze, so that high-temperature and high-pressure gas is further prevented from entering.
