Abstract
The utility model provides a safety detonator which comprises a detonator shell of which one end is open and the other end is closed, wherein a main charge is pressed at the closed end of the detonator shell; a booster explosive is filled close to the main charge; an inner tube is arranged at a position, which is close to the booster explosive, in the detonator shell; the inner tube faces an opening at one end of the booster explosive; one end which faces the opening of the detonator shell is closed; a cross prefabricated igniting port is formed in the closed end of the inner tube; the booster explosive is pressed at the closed end of the inner tube; a loose explosive is filled in the inner tube between initiating explosive and the booster explosive. According to the safety detonator, a phenomenon of explosive leakage in the process of pressing the explosive in a reinforcing cap structure is effectively avoided, and the production safety of the product is effectively improved.
Description
Technical field
The utility model relates to a kind of industrial explosive material.
Background technology
At present, at civil explosive materials industrial, in the structure of detonator, can't do without strengthening cap, strengthening cap must stay a flash hole, while suppressing priming explosive in strengthening cap, exist the phenomenon that priming explosive spills from flash hole, priming explosive is more responsive, the priming explosive spilling exists the possibility of blast in moulds of industrial equipment, and the production security of product is poor.
Summary of the invention
Goal of the invention of the present utility model is to overcome the above-mentioned deficiency of prior art, and a kind of prefabricated interior tubular type safety detonator that can effectively improve products production security is provided.
The technical solution of the utility model is: the shell that comprises an end opening, one end sealing; Main charge is pressed on the blind end of shell; Near main charge, be filled with booster explosive; In shell, near booster explosive, be placed with an inner tube; Inner tube surface is to booster explosive one end opening, towards one end sealing of shell opening; Inner tube blind end is provided with the prefabricated biography burner of cruciform; Priming explosive is pressed on inner tube blind end; In inner tube between priming explosive and booster explosive, be filled with loose explosive.
The prefabricated biography burner of described cruciform is criss-cross groove, in described criss-cross groove and shell, does not connect.
Leakage medicine phenomenon when the utility model structure efficiently solves the pressing of strengthening cap structure, has effectively improved the production security of product.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of inner tube.
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is the upward view of Fig. 2.
In figure, 1, shell, 2, inner tube, 3, main charge, 4, booster explosive, 5, priming explosive, 6, loose explosive, 7, flash hole, 8, prefabricated biography burner.
Embodiment
In Fig. 1, the utility model comprises shell 1, inner tube 2; The inner segment of shell 1 is loaded main charge 3, booster explosive 4 from inside to outside successively, the outer inner tube 2 that is equipped with of booster explosive 4; Inner tube 2 one end openings, one end sealing, blind end is provided with criss-cross prefabricated biography burner 8.Inner tube 2 press-fited before shell 1, by blind end, outwards loaded successively priming explosive 5 and a small amount of loose explosive 6, on specific moulds of industrial equipment, priming explosive 5, loose explosive 6 was pressed into piece, and during compacting, prefabricated biography burner 8 is backed down and forms flash hole 7.
In Fig. 2, Fig. 3, Fig. 4, inner tube 2 one end openings, one end sealing, blind end is provided with criss-cross prefabricated biography burner 8.The prefabricated biography burner of cruciform is criss-cross groove, in criss-cross groove and shell, does not connect.
Concrete making processes of the present utility model: shell 1 is packed in specific moulds of industrial equipment, pack successively main charge 3, booster explosive 4 into, with localization method or the pressing respectively of level pressure method; Inner tube 2 is packed in specific moulds of industrial equipment, then in inner tube 2, pack priming explosive 5 into, loose explosive 7, with localization method or the pressing of level pressure method, during compacting prefabricated biography burner 8 backed down form flash hole 7; The inner tube suppressing 2 is pressed fit in shell 1, the utility model detonator is made complete again.
