Abstract

The utility model discloses a casing for a high-explosive type initiating tool. The casing for the high-explosive type initiating tool is made of a plastic material and comprises an outer casing body. The upper end of the outer casing body is open, the lower end of the outer casing body is closed, the closed end of the outer casing body is provided with two functional holes, and two positioning pipes right facing the two functional holes are arranged in the outer casing body. An inner casing body is arranged inside the outer casing body, the lower end of the inner casing body is fixed at the bottom of the outer casing body, the upper end of the inner casing body is open, and the two positioning pipes are located in a cavity of the inner casing body. The casing for the high-explosive type initiating tool is reasonable in structural design, small in volume, convenient to use, safe and reliable, decreases using amount of a high-energy initiating explosive, reduces the cost and achieves initiating effect same as the effect of a large charged initiating tool.

Description

A kind of high quick-fried type detonation tool housing

Technical field

The utility model belongs to the industrial explosive material production technical field, especially relates to a kind of high quick-fried type detonation tool housing.

Background technology

Detonation tool is for the explosive of igniting desensitized explosive or Chamber Blasting, belongs to the relaying explosive.Existing detonation tool is to adopt take TNT as the main body powder charge basically, and press-fiting or sneak into the cylindric expansion that fusing is cast into behind Tai An or the hexogen can initiating equipment.At present, detonation tool mainly adopts columned hollow paper shell or plastic casing, and two detonator holes or a detonator hole and a primacord hole are arranged in the housing, in the production process, assembles with casting mold.Require the explosive payload of detonation tool large, too peace in the powder charge or hexogen large percentage, otherwise be difficult to guarantee the initiating ability of detonation tool, but too peace, hexogen price are very expensive, cause the production cost of detonation tool significantly to rise, also brought the safety problem in the detonation tool production process.

Summary of the invention

For addressing the above problem, the purpose of this utility model provides a kind of reasonable in design, high quick-fried type detonation tool housing easy to use, it is under the prerequisite that guarantees product quality, use less dose just can reach the Detonation Initiation Effect of large powder charge, reduced too peace or these uses expensive, high explosive of hexogen.

For achieving the above object, the utility model adopts following technical scheme:

A kind of high quick-fried type detonation tool housing, it is plastic material, comprises shell body, the shell body upper end open, lower end closed, the blind end of shell body is provided with two functional holes, is furnished with two positioning pipes over against two functional holes in the shell body; Shell body inside is provided with an inner housing, and the inner housing lower end is fixed on the shell body bottom, the inner housing upper end open, and two positioning pipes are positioned at the cavity of inner housing.

The quick-fried type detonation tool of described height housing, its shell body lower end is sealed by base plate, the base plate center offers notch, notch is provided with the location-plate that shape with it adapts, location-plate top is stretched in the shell body, location-plate is provided with two functional holes, and inner housing is positioned at location-plate top, and the shape of cross section of inner housing, size and the shape of cross section of location-plate, big or small identical.

The quick-fried type detonation tool of described height housing, the height of its inner housing is not more than the shell body height, is not less than half of shell body height, and is not less than the height of minimum gauge detonator.

The quick-fried type detonation tool of described height housing, its shell body, location-plate, positioning pipe and inner housing are once injection moulding.

Owing to adopt aforesaid technical scheme, the utlity model has following superiority:

The quick-fried type detonation tool of this height housing, its reasonable in design, volume is little, easy to use, safe and reliable, shell body, location-plate, positioning pipe and inner housing are once injection moulding, water repelling property is good, inner housing be provided with the cast that is beneficial to the high energy priming, when manufacturing a finished product, simplified production technology, increase substantially production efficiency, can reduce that the high energy priming is pacified very much or the use amount of hexogen, reduced cost, initiating ability is large, has reached the Detonation Initiation Effect identical with large charge detonates tool.

The specific embodiment

Also by reference to the accompanying drawings the technical solution of the utility model is described in further detail below by embodiment.

As shown in Figure 1, 2, 3, the quick-fried type detonation tool of height of the present utility model housing, it is plastic material, comprises shell body 1, the shell body upper end open, the lower end is sealed by base plate, and the base plate center offers notch, and notch is provided with the location-plate 4 that shape with it adapts, location-plate top is stretched in the shell body, location-plate is provided with two functional holes, is furnished with two positioning pipes over against two functional holes in the shell body, is respectively the first positioning pipe 3, the second positioning pipe 5; Shell body 1 inside is provided with an inner housing 2, the inner housing lower end is fixed on the location-plate, the shape of cross section of inner housing, size and the shape of cross section of location-plate, big or small identical, the inner housing upper end open, the first positioning pipe 3, the second positioning pipe 5 are positioned at the cavity of inner housing.

Two above-mentioned positioning pipes are used for two detonators of plug-in mounting or primacord and detonator.

The height of described inner housing is not more than the shell body height, is not less than half of shell body height, and is not less than the height of minimum gauge detonator.The height of minimum gauge detonator is 60mm, and therefore, the height of inner housing is not less than 60mm.

The quick-fried type detonation tool of described height housing, its shell body 1, location-plate 4, the first positioning pipe 3, the second positioning pipe 5 and inner housing 2 are once injection moulding.
