Abstract
The utility model provides a rubber igniter plug of a fuse type ignition detonator, and belongs to the of the civil blasting accessories, in particular to the rubber igniter plug for a delay type ignition detonator. The aim of the utility model is realized through the following technical proposal: a bottom hole is opened at the inner side of the lower part of the igniter plug; the wall of the bottom hole presents a zigzag shape; ignition composition is filled in the interior of the bottom hole of the igniter plug. The utility model reduces the cost of the detonator, being more than 90 percent compared with the core tube delay type ignition detonator, and being above 80 percent compared with the lead delay type ignition detonator; at the same time, the problems of the fuse type delay ignition detonator that the misfire exists and the change in delay time is not stable are completely solved, the production process of the current delay ignition detonator with high delay time is reduced, and the quality of the ignition detonator with high delay time is improved.
Description
Technical field
The utility model belongs to civilian initiating equipment technical field, is specifically related to the rubber igniter plug that a kind of formula Nonel detonator of delaying is used, international Patent classificating number: F42B 3/00.
Background technology
A high second amount extension Nonel detonator part of domestic production at present is tubular type extension method in taking, another part is to adopt plumbous extension body formula extension method, and interior pipe extension body formula and plumbous extension body formula Nonel detonator have complex manufacturing, shortcoming that cost is high.The rubber stopper that uses on the Nonel detonator has been the anastomosis of detonator and blasting cap at present, because it is fewer that detonator is ignited the amount of back generation high temperature and high pressure gas, be not enough to open the steam vent on the detonator body, had a strong impact on the performance of fuse cord extension formula Nonel detonator.
Summary of the invention
The fuse cord formula Nonel detonator rubber igniter plug that goal of the invention of the present utility model provides a kind ofly can make that fuse cord formula Nonel detonator cost reduces, storage period is long, second amount is stablized, is difficult for miss-firing.
Goal of the invention of the present utility model is achieved through the following technical solutions: the lower inside at igniter plug has bottom outlet; Described bottom outlet wall indentation; Bottom outlet inside at igniter plug is filled with ignition charge;
Using method of the present utility model is: the utility model is installed in the top of fuse cord formula Nonel detonator, is inserted with detonator in the inside of igniter plug, this detonator communicates with the ignition charge of igniter plug bottom filling; The room that the 5-8 millimeter is arranged between igniter plug and extension fuse cord has 1-2 diameter and is 2 millimeters steam vent, at the outside of steam vent adhesive tape sealing of hole apart from the capsule place of the position correspondence of extension fuse cord upper surface 1-2 millimeter in this room.A small amount of high temperature and high pressure gas that detonator produces can be transformed into a large amount of high temperature and high pressure gas, and when the interior fuse cord of Nonel detonator was lighted, steam vent can be opened smoothly.
The utility model has reduced the cost of detonator, compare with the Nonel detonator of interior pipe extension formula and to reduce cost more than 90%, compare with lead extension body formula Nonel detonator and to reduce cost more than 80%, thoroughly having solved simultaneously fuse cord formula extension Nonel detonator miss-fires and second unstable problem of amount, simplify the production technology of present high second amount extension Nonel detonator, improved the quality of high second amount Nonel detonator.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the lower inside at igniter plug 1 has bottom outlet; Described bottom outlet wall indentation 2; Bottom outlet inside at igniter plug is filled with ignition charge 3;
It is can be securely fixed in the bottom outlet unlikely coming off after making the ignition charge drying that described bottom outlet wall adopts the purpose of laciniation.
Making step of the present utility model is:
The first step is made rubber stopper as shown in Figure 1 with rubber.Second step was coated with ignition charge at the bottom outlet of rubber stopper.The 3rd step is dry, be coated with damp-proof paint.
Claims (2)
