Abstract
The utility model relates to a time lead wire with high precision, multipurpose and dual fail-safe, which comprises a material for enwrapping (3), a combustion-supporting rope (2) and a core (3) made of black powder. The combustion-supporting rope (2) cuts in the black powder (1). The utility model is characterized in that 2 or 3 combustion-supporting ropes (2) are arranged in the core made of black powder. With 100% success rate of transferring fire and absolute reliability, the utility model resists moisture, shortage of powder, insufficient powder and immersion. Therefore, the utility model is applicable for fireworks and igniter cord used in industry.
Description
Technical field the utility model relates to a kind of timing lead-in wire, and particularly the double insurance of high precision multi-usage regularly goes between.
Existing general timing lead-in wire of background technology and industrial blasting fuze are single cored structure, mainly be that black powder twists in the looping thing, in making processes,, quality problems such as few medicine, disconnected medicine, empty medicine bowl often occur owing to machinery, human factor, unavoidable Serious Accident takes place, and causes casualties.
Summary of the invention is in order to overcome the deficiency of prior art product, and the utility model provides the double insurance of a kind of high precision multi-usage regularly to go between.
The technical scheme that solves the utility model technical problem is to adopt twin-core or multicore structure, promptly interts the combustion-supporting rope of 2-3 root in gunpowder and looping thing, and this combustion-supporting rope can be cotton thread or the wire of handling through the particular chemical pharmaceutical composition.
Positively effect of the present utility model is: both can be used for fireworks, can be used for industrial blasting fuze again, be not afraid of and make moist, and the disconnected medicine of few medicine, 100% passes fire, and it is reliable to be perfectly safe.
Appended drawings is the utility model structural representation, among the figure: 1, combustion-supporting rope, 2, black powder, 3, the looping thing.
Embodiment: referring to accompanying drawing, the utility model is by looping thing 3, and black powder 2 and combustion-supporting rope 1 are formed, and combustion-supporting rope 1 interts in black powder 2, and wherein combustion-supporting rope 1 is provided with two to three.This combustion-supporting rope is through chemical agent: red lead, silica flour, antimony sulfide or potassium perchlorate, seedling pastil, powdered carbon; Or the cotton thread or the wire of three compositions-treated such as flavor powder etc., use the cotton paper winding, coating interts in the black powder core of making after drying outward.
Claims (1)
1, the double insurance of a kind of high precision multi-usage regularly goes between, and by looping thing (3), combustion-supporting rope (2) and black powder core (1) are formed, and combustion-supporting rope (2) is interspersed in the black powder core, it is characterized in that being provided with in the black powder core two to three combustion-supporting ropes (2).
