The technical solution of the present invention and how to solve the above technical problems will be described in detail with specific embodiments.

The detonation tool provided by the embodiment of the application of the utility model, as shown in fig. 1, comprises a shell 100, an end cover 200, a detonation cartridge 300 and a charge column 400; the end cap 200 is disposed at a first axial end of the casing 100, the initiation core 300 is suspended in the inner cavity of the casing 100, and the charge column 400 is filled between the inner wall of the casing 100 and the initiation core 300. The end cap 200 may be placed over the housing 100, typically by providing mating structures that mate with one another, and inserting a portion of the housing 100 into the end cap 200.

The initiation cartridge 300 includes a horizontal portion 310 and a vertical portion 320 perpendicular to each other, a first end of the vertical portion 320 is located in the middle of the horizontal portion 310, and an end surface of a second end of the vertical portion 320 is spaced apart from an end surface of a second end of the casing 100 in an axial direction by a predetermined distance. The initiation core 300 is T-shaped, and in the finished initiator, the initiation core 300 is suspended in the casing 100, and the surrounding is filled with the explosive. The vertical portions 320 are distributed along the axial direction of the housing, that is, the axial direction of the vertical portions 320 is the axial direction of the housing, the radial direction of the vertical portions 320 is the axial direction of the housing 100, and the radial direction of the vertical portions 320 is the length direction of the transverse portions 310.

A pair of detonator mounting holes 110 are provided in the charge column 400, which are located in the radial direction of the housing and distributed on both sides of the vertical portion 320. The orifice of the detonator mounting hole 110 is located on the end face of the second axial end of the casing 100. The size of the detonator mounting hole 110 is determined according to the size of the detonator selected specifically, and the detonator can be mounted in the shell 100 through the detonator mounting hole 110, so that the detonator is at least partially contacted with the initiating explosive core 300. The detonator mounting hole 110 is generally provided in two, which ensures the detonation reliability of the detonator.

The utility model provides an initiating explosive device is through setting up the shell into the integrated configuration of casing 100 and end cover 200 to can set up injection hole 210 on end cover 200, make initiating explosive device accessible fill formula production, the product size is compared in compression moulding's product and is had bigger medicine core filling space, is favorable to forming the wider district that detonates of scope in casing 100.

And, because the flux core adopts T style of calligraphy structure, can form at the top and the one end side of detonator mounting hole 110 (also called functional hole) and surround the region, when reducing detonating flux core 300 size and save raw materials, can form the detonation zone of wider scope in casing 100, as long as the detonator side contacts the flux core side, even do not insert the detonator to the hole bottom of detonator mounting hole 110, also can stably detonate, improved the detonation reliability of initiating explosive.

Through setting up detonator retainer plate 120, carry out certain degree reinforcement to the detonator, prevent to assemble the detonator in detonator mounting hole 110 and take place to drop at the transportation or the in-process of installing the big gun hole. The detonator fixing ring 120 can be made of rubber materials, and a mode that the inner diameter of the detonator fixing ring 120 is slightly smaller than the aperture of the detonator mounting hole 110 can be specifically adopted, so that the detonator fixing ring 120 can be abutted and buckled on a detonator.

Optionally, in a specific embodiment of the foregoing implementation, as shown in fig. 2 and 3, a protruding block is provided on an inner side wall of the detonator fixing ring 120, a cross section of the protruding block along the radial direction of the casing 100 is a right triangle, a first acute angle of the right triangle is close to the detonation core 300, a second acute angle is close to an end face of the second end of the casing 100 in the axial direction, and the first acute angle is larger than the second acute angle. Set up the bump that has special shape on the inside wall of detonator retainer plate 120, this bump presents for the wedge, and the inclined plane is located the hole pore wall of detonator retainer plate 120, because the cross section is right triangle-shaped, and first acute angle wherein is greater than the second acute angle, and the second acute angle is close to the second end of casing 100, this bump is equivalent to the "barb" in detonator retainer plate 120, and the detonator can conveniently stretch into in detonator mounting hole 110, but hope to take out the detonator from detonator mounting hole 110, then can receive the hindrance of bump.
