Abstract

The utility model relates to a plastic pipe delay detonator which comprises a detonating tube, a latching ring, a plastic detonation delay tube, and a flash detonator. The plastic detonation delay tube is filled with black powder, with one end being provided with the latching ring and the other end being inserted into the flash detonator. The detonating tube is inserted into the plastic detonation delay tube through the latching ring. The plastic pipe delay detonator has advantages of high time accuracy, simplified structure, reduced fabrication process, low production cost, improved structural quality, good moisture-proof property, as well as easy, safe and reliable use.

Description

The plastic pipe delay detonator

Technical field

The utility model relates to a kind of plastic pipe delay detonator.

Background technology

The present non-electric second delay detonator that uses, generally be to make the extension body with fuse cord, come the control time poor with its length, detonator generally is high explosion velocity (explosion velocity is the 1650-2000 meter per second), doing assembling with plastic bushing connects, product structure is complicated, time precision is bad, and moistureproof moist bad, production process is more.

Summary of the invention

The purpose of this utility model provides a kind of plastic pipe delay detonator, use this plastic pipe delay detonator, can improve time precision and simplify product structure, reduce that operation is made, reduced production costs, improves architecture quality, moisture proof is good, esy to use, safe and reliable.

The purpose of this utility model is achieved in that by detonator, bayonet socket ring, plastics leads the plastic pipe delay detonator that the fire extension is managed and blasting cap is formed, plastics are led in the fiery extension pipe black powder, the one end has bayonet socket ring, the other end to insert in the blasting cap, and detonator inserts plastics by the bayonet socket ring and leads in the fiery extension pipe.

The utility model is owing to be to lead fire with plastic tube dress black powder to delay to manage, come the control time poor with the measuring length in its pipe, the low explosion velocity (explosion velocity is the 1550-1400 meter per second) of control detonator, avoided the destructiveness of high explosion velocity Hong wave impact, avoided dashing and taken off connecting tube and break up delay powder; Plastic tube has strengthened the ignition performance, can protect the black powder burning steadily to advance preferably, and degree of packing is also comparatively even; Be beneficial to according to the different burning velocity of black powder and freely adjust the metering loaded length and can control 5-7 section not; Plastic tube both can have been made fuse primer and control time difference and use with also doing connecting tube, has the advantage of achieving many things at one stroke with the supporting improvement of low speed detonate-tube, can remedy existing second delay detonator, its fuse cord time precision difference and on the process structure, on the production process, use the deficiency of first-class existence.

Below in conjunction with attached detailed description concrete structure of the present utility model, but structure of the present utility model is not limited to shown in the accompanying drawing.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Among Fig. 1, use plastic plug, the black powder 4 that interior dress is refuted out from fuse cord is led the fire pipe 3 of delaying, low speed detonate-tube 1 pierces into plastic plug, on the position that connects cover bayonet socket ring 2 and clamping, plastic plug wraps the paper tape dilated diameter and compresses into blasting cap 5 rooms and get final product.

Control low speed detonate-tube 1 low speed is led quick-fried, and it is felt quick-fried performance and reaches test stone, a 8# industrial plain detonator 5 30 low speed detonate-tubes 1 that detonate simultaneously, and pass 30 plastic plug developmental tubes of combustion simultaneously; Plastics extension pipe 3 and low speed detonate-tube 1 matching performance, the inflammable sensitivity of its quick-fried biography igniting suits, and can reach the requirement accurately of igniting; Combustibility, data show can clearly see the speed that fire burns advances, and reaches the requirement that burning steadily advances; Spray combustion performance, its spray combustion be 15 millimeters fuse cord (keeping flat naturally then equal approximately with fuse cord) at interval, shows that having enough biography firepower detonator 5 of igniting detonates, and reaches and sprays the strong requirement of combustion power; The metering powder charge, data show the requirement that reaches the raising time precision.

Claims

1, a kind of plastic pipe delay detonator, it is characterized in that: lead delay pipe (3) and blasting cap (5) of fire by detonator (1), bayonet socket ring (2), plastics and form, plastics are led fire and are delayed in the pipe (3) black powder (4) is arranged, the one end has bayonet socket ring (2), the other end to insert in the blasting cap (5), and detonator (1) inserts plastics by bayonet socket ring (2) and leads in the fire extension pipe (3).
