Background

The existing detonator is composed of a tube shell, a reinforcing cap, an ignition powder, a delay powder, an initiating powder, an explosive and the like, and is widely used for a detonator matching product. As shown in fig. 2: in the conventional detonator, a single-end straight-through type tube shell 18 is adopted, and a reinforcing cap 19 is pressed into the mouth of the detonator for sealing the detonator.

While exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the utility model to those skilled in the art.

Example 1:

referring to fig. 1, a delay combination detonator tool comprises a first shell 1 and a second shell 2. Wherein the first housing 1 is detachably connected with the second housing 2. When the first casing 1 is detachably connected with the second casing 2, the first casing 1 is communicated with the inner space of the second casing 2.

The outer surface of the first shell 1 is cylindrical with a side wall with a certain thickness, and the inside is provided with a communicated space. The communicated space is divided into three parts, namely a containing cavity 6, a first fire passage 10 and a first mounting groove 11 from top to bottom. Wherein the accommodating cavity 6 can be used for accommodating a needling fire cap 12 or a safety plug.

The outer surface of the second shell 2 is cylindrical with a side wall with a certain thickness, and the inside is provided with a communicated space. The space communicated with the second housing 2 includes a fire passing space 7, a second mounting groove 8 and a third mounting groove 9. The fire passing space 7 comprises a fire passing hollow round cake 13 and a second fire passage 14 and a third fire passage 15 which extend downwards from two sides of the fire passing hollow round cake 13. The second flame path 14 communicates with the second mounting groove 8, and the third flame path 15 communicates with the third mounting groove 9. The second mounting groove 8 and the third mounting groove 9 are spaced apart, and the second mounting groove 8 and the third mounting groove 9 are spaced apart by a central solid area inside the second housing 2 between the second mounting groove 8 and the third mounting groove 9.

The first detonator 3, the second detonator 4 and the third detonator 5 are respectively detachably arranged in the first mounting groove 11, the second mounting groove 8 and the third mounting groove 9;

when the first detonator 3, the second detonator 4 and the third detonator 5 are installed, the middle parts of the shells of the outer walls of the first detonator 3, the second detonator 4 and the third detonator 5 are coated with a proper amount of adhesive on the whole body, and then the first detonator 3, the second detonator 4 and the third detonator 5 are respectively pushed into the first installation groove 11, the second installation groove 8 and the third installation groove 9. Because the first detonator 3, the second detonator 4 and the third detonator 5 are matched with the first mounting groove 11, the second mounting groove 8 and the third mounting groove 9 in size, the detonators can be plugged into the grooves and cannot fall from the grooves. After the detonator is coated with the adhesive and then placed in the corresponding mounting groove, the adhesive has certain fluidity, so that the first shell 1 and the second shell 2 are required to be inverted upside down for 5 minutes to enable the adhesive to be completely solidified, and a small amount of liquid flows to the top end of the detonator from the side face to play a role in sealing to a certain extent, and the fixing area is also increased in the downflow process.

The first detonator 3, the second detonator 4 and the third detonator 5 are sequentially filled with ignition powder, delay powder and initiating powder with different dosages from top to bottom, and the detonation time is determined according to the quantity of the delay powder.

When the first housing 1 and the second housing 2 are connected, the internal space communication means that the fire passing space 7 inside the second housing 2 is communicated with the first installation groove 11 inside the first housing 1.

The sidewall of the second housing 2 is the same thickness and bottom area as the sidewall of the first housing 1. The upper part of the side wall of the second shell 2 and the lower part of the first shell 1 are provided with corresponding threads, buckles, clamping grooves or planes which are oppositely connected in a detachable mode through glue adhesion and the like.

The first shell 1 and the second shell 2 are detachably connected, so that one of the first shell and the second shell is damaged, the other one of the first shell and the second shell can still be connected with a new shell, and the manufacturing cost of parts is saved; the detonator can be installed simultaneously by the first shell 1 and the second shell 2, mutual influence is avoided, assembly is convenient, and operation efficiency is improved.

When the detonator tool is in a use state, the needling fire cap 12 is installed in the accommodating cavity 6, and the needling fire cap 12 is ignited by penetrating the inside of the needling fire cap 12 through the firing pin. The upper end of the igniting cap 12 is horizontal, the lower end is arch bridge mounted, and one end is provided with an opening. The ignition cap 12 is ignited after being penetrated by the firing pin, and the flame flows out from the opening of the internal space of the ignition cap 12 and flows into the first mounting groove 11 under the action of gravity.

The structural design not only can meet the requirement that the first detonator 3 is inserted into the first mounting groove 11, but also can ensure that the first detonator 3 cannot slide off from the groove in the inversion process of the first shell 1, and ensure the bonding performance of the adhesive.

Referring to fig. 1, the top and bottom centers of the first detonator 3, the second detonator 4 and the third detonator 5 are all provided with inflammable silk, and the area of the top silk is smaller than that of the bottom silk.

Referring to fig. 1, the first detonator 3 corresponds to the middle part of the bottom end of the first fire passage 10, that is, the silk at the top of the first detonator 3 is completely located below the first fire passage 10, and the flame falls from the inside of the first fire passage 10 to the silk at the top of the first detonator 3 to ignite the silk, so that the flame enters the inside of the first detonator 3 to achieve the detonation effect.

The silk at the bottom of the first detonator 3 corresponds to the middle part of the top end of the firing space 7, the flame after detonating the detonator enters the firing space 7, and the flame is divided into two paths for respectively igniting the silk at the tops of the second detonator 4 and the third detonator 5 and then detonating the second detonator 4 and the third detonator 5 from the firing hollow round cake 13 of the firing space 7 and the second fire passage 14 and the third fire passage 15 which extend downwards from two sides of the firing hollow round cake 13.

The silk at the bottoms of the first detonator 3, the second detonator 4 and the third detonator 5 can prevent the powder in the detonator from falling.

When only the first detonator 3 and the second detonator 4 need to be ignited, the third mounting groove 9 can be plugged by safety plugs with the rest sizes, so that the flame can circulate only in the first mounting groove and the second mounting groove 8; when only the first detonator 3 and the third detonator 5 need be ignited, the second mounting groove 8 can be plugged with safety plugs of the remaining dimensions so that the flame circulates only in the first mounting groove and the third mounting groove 9.
