Abstract

The utility model discloses a civilian detonator postponing igniter tube, aiming at providing a high-energy detonator igniter tube with postponing effect. The igniter tube at least includes a tube shell 1, water resisting amorce 2, a postponing piece 3, and an igniter piece 4. The water resisting amorce 2, the postponing piece 3, the igniter piece 4, and a plastic detonator 6 are orderly fixed at the bottom of the inner layer of the tube shell 1. The plastic detonator 6 can be a common type or a high-strength type, is connected with an igniter tube by a plastic bayonet plug 5, and extends out of the tube shell 1 from the inside of the tube shell 1. The upper part of the plastic bayonet plug 5 extends out of the tube shell 1, and is sleeved on the outer wall of the plastic detonator 6. The appearance of the igniter tube is basically similar to the appearance of an exploder, the tube shell 1 is a metal tube shell with a crisscross groove line or a blind hole at the bottom; a weak point is formed to ensure the tube shell to be melted into an passage delivering the energy when the igniter tube acts. The civilian detonator postponing igniter tube has the advantages of water resistance, static resistance, safe usage, simple network design, convenient connection, reliable ignition, and precise postponing, etc.

Description

Priming Tube Delay Ignition Tube

Technical field

The utility model relates to a kind of civilian ignition device, particularly a kind of Priming Tube Delay Ignition Tube.

Background technology

Ignitron is widely used in the building stones mining blasting engineering, and separating technology is vital in exploitation, and it to mine benefit influence greatly plays a decisive role to the raising of the utilization rate of resource.In the separation method of rectangular block of stone commonly used, it is comparatively general that low-yield explosive (black powder etc.) decrepitation method uses, but the back produces a large amount of environmentally harmful sulfurous gas and is eliminated gradually because black powder burns.Along with the attention of countries in the world to the protection environment, the many countries such as the U.S., Italy, Austria, Germany and Switzerland etc. generally adopt the high-energy combustion agent based on military retired propellant powder to replace black powder to carry out exploitation of stone.At present, the ignition device of prior art generally adopts electric match, has in the use that ignition ability deficiency, moisture-sensitive, water proofing property and antistatic property are poor, production, storage and a damaged easily shortcoming of transportation Chinese medicine head.This lights high-energy combustion agent with regard to the ignition device with accurate defer time that needs a kind of high security, high reliability, high energy and be convenient to operate.

Summary of the invention

One of the purpose of this utility model provide a kind of have delayed effect, water resistance good, safe in utilization, be convenient to operate, help protecting environment, be suitable for controlling the Priming Tube Delay Ignition Tube that blast is used.

Two of the purpose of this utility model provides a kind of Priming Tube Delay Ignition Tube that is not subjected to environment for use restriction, storage and convenient transportation, to overcome the deficiencies in the prior art.

The purpose of this utility model is to realize like this, design a kind of Priming Tube Delay Ignition Tube, it is characterized in that: which comprises at least shell 1, anti-water spot gunpowder 2, extension part 3, igniter 4, rubber bayonet socket plug 5, plastic detonating tube 6, shell 1 is that an end has the elongated tubular body that wave closes up, shell 1 internal layer bottom is fixing point gunpowder 2 successively, extension part 3, igniter 4, plastic detonating tube 6, link together and in shell 1, stretch to outside the shell 1 by rubber bayonet socket plug 5 and ignitron, rubber bayonet socket plug 5 tops extend to outside the shell 1, are socketed on plastic detonating tube 6 outer walls.

Described shell 1 bottom thickness is between 0.5mm～0.7mm.

The cross recess impression is arranged at described shell 1 bottom.

Described shell 1 bottom blind hole.

Described ignition charge 2 is anti-water spot gunpowder.

The defer time scope of described ignitron is 0s～9s.

Because the utility model is to connect plastic detonating tube 6 by the end at shell 1 by rubber bayonet socket plug 5, rubber bayonet socket plug 5 adopts elastomeric material water-fast, that moisture-proof is good to make, and loads anti-water spot gunpowder in the bottom of shell 1.Between plastic detonating tube 6 and anti-water spot gunpowder is extension part 3 and igniter 4, and overall tightness is good.Adopt plastic detonating tube 6, not influenced by environment for use, antistatic property is good, is not easy breakage in production, storage and the transportation, can adapt to various traffic conditions.Therefore, the utility model with compared with prior art, its remarkable advantage is: have anti-water, antistatic, safe in utilization, networking simplicity of design, easy to connect, characteristics such as igniting is reliable, time-delay is accurate.
