Abstract
The utility model discloses a dual-detonator primer, which comprises a shell. One end of the shell is opened, while the other end is closed; the dual-detonator primer has the key points that an interpenetration pipe is arranged at one side of the outside of the shell; two detonator holes are arranged at the closed end of the shell; the shell is internally provided with two bottom-closed detonator placing pipes; the opened ends of the detonator placing pipes are communicated with the detonator holes; an elastic detonator fixing clip is arranged on the detonator hole; and the shell, the detonator placing pipe, the interpenetration pipe and the detonator hole are injection-molded by one step. In the dual-detonator primer, the structural design is rational and the use is convenient; as the shell, the detonator placing pipe, the interpenetration pipe and the detonator hole are in injection molding once, the water resistance is good, the types of the main charges of the primer are widened, and the sensitiveness of the grain is reduced. The dual-detonator primer solves the technical problems of weak water resistance, high sensitiveness of the grain and low operation safety existed in the prior art.
Description
Technical field the utility model belongs to explosion utensil technical field, relates to a kind of detonation tool shell that uses in blasting engineerings such as cutting into a mountain, open a mine, build water conservancy projects, is specifically related to the double detonator detonation tool.
The blasting cap initiation tool of background technology prior art generally adopts the paper shell, during production and casting mold assemble, inject high explosive after cooling move back mould.This detonation tool shell is subjected to the influence of humidity easily, exist water-resistance poor, the technical problem that the susceptibility of powder column is high, cause the phenomenon of failing to explode easily, influence the effect of explosion, the big gun hole that even more serious is after failing to explode not only wants elapsed time and resource to go to remove or ignite, and staff's personal safety is had great threat, operates dangerous.
The summary of the invention the purpose of this utility model is to solve prior art to have that water-resistance is poor, the susceptibility of powder column high and operate unsafe technical problem, provides a kind of double detonator detonation tool, to overcome the deficiencies in the prior art.
To achieve these goals, the utility model double detonator detonation tool, it comprises housing, an end opening of housing, other end sealing; Its main points are that the outer side of housing is provided with interspersed pipe, the blind end of described housing is provided with two detonator holes, be provided with the detonator disposed tubes of two bottom locks in the housing, the openend of detonator disposed tubes is communicated with the detonator hole, described detonator hole is provided with the fixing card of elasticity detonator, and described housing, detonator disposed tubes, interspersed pipe and detonator hole are once injection moulding.
For the ease of the interspersed guiding of detonator and primacord, described interspersed pipe and housings close end corresponding position are provided with a guide groove.
The utility model reasonable in design, easy to use, because housing, interspersed pipe, detonator disposed tubes and detonator hole are once injection moulding, water repelling property is good, has widened detonation tool main charge kind, has reduced the susceptibility of powder column.The utility model has solved that prior art exists that water-resistance is poor, the susceptibility height of powder column and the low technical problem of processing safety.
Description of drawings Fig. 1 is the utility model structural representation stereogram;
Fig. 2 is the utility model structural representation vertical view.
Among the figure 1, housing 2, the fixing card 3 of elasticity detonator, detonator disposed tubes 4, guide groove 5, intert pipe 6, detonator hole
The specific embodiment sees figures.1.and.2, and it comprises housing 1 the utility model, an end opening of housing 1, other end sealing; Housing 1 an outer side is provided with to intert manages 5, the blind end of described housing 1 is provided with two detonator holes 6, be provided with the detonator disposed tubes 3 of two bottom locks in the housing 1, the openend of detonator disposed tubes 3 is communicated with detonator hole 6, described detonator hole 6 is provided with the fixing card 2 of elasticity detonator, described interspersed pipe 5 is provided with a guide groove 4 with the blind end corresponding position of housing 1, and described housing 1, detonator disposed tubes 3, interspersed pipe 5 and detonator hole 6 are once injection moulding.
During use, explosive is filled in the plastic casing 1, cover at housing 1 openend with gland again and fix through the heat seal fusion, and then two detonators that are connected with primacord are penetrated the outer interspersed pipe 5 of housing 1, pass the fixing card 2 of elasticity detonator by guide groove 4 again and enter in the detonator disposed tubes 3, get final product.
The utility model is also referred to as: a side penetrates double detonator detonation tool plastic housing.
Claims (2)
1. double detonator detonation tool, it comprises housing, an end opening of housing, other end sealing; It is characterized in that the outer side of housing is provided with interspersed pipe, the blind end of described housing is provided with two detonator holes, be provided with the detonator disposed tubes of two bottom locks in the housing, the openend of detonator disposed tubes is communicated with the detonator hole, described detonator hole is provided with the fixing card of elasticity detonator, and described housing, detonator disposed tubes, interspersed pipe and detonator hole are once injection moulding.
