Abstract
The utility model discloses a low-strength detonating blasting cap, which comprises a cap casing and is characterized in that a main charging box body, a safe detonating body, a delay element, a rubber plug and a detonating tube are arranged from bottom to top sequentially in the cap casing; and the lower end of the detonating tube is inserted in the rubber plug. The low-strength detonating blasting cap has a simple structure and convenience in use, by means of the arrangement of the delay element, the length of the delay element can be adjusted according to the networking blasting time so as to meet the requirement of networking blasting; simultaneously, no primary explosive contains in the cap casing, the strength is small while the safety performance is high; and further fragments generated by the explosion are few, and the fragment energy is low, so that detonating network of detonating blasting cap cannot be cut. The low-strength detonating blasting cap solves the technical problems of low safety performance, poor entire explosive effect and unsuitability of networking explosion in the prior art.
Description
Technical fieldThe utility model belongs to the blasting technique field, is specifically related to a kind of low power and leads quick-fried detonator.
Background technologyOf the prior artly lead quick-fried detonator, cut into a mountain, excavation and civil blast etc. be widely used in the field, thisly lead the impact that quick-fried detonator includes priming and is subjected to its structure, the explosion power is large, although can play the effect of explosion, there is shortcomings, because its explosion power is large, have larger potential safety hazard in production, transportation and use procedure, security is low; Simultaneously, thisly lead quick-fried detonator and be subjected to its powerful explosion power, the fragment that produces after blast can cut leads quick-fried blasting cap initiation network, and causing part to lead quick-fried detonator can't explosion, affects the global blowup effect; And, thisly lead quick-fried detonator and can't adjust defer time, the needs of the explosion that is not suitable for networking.
Summary of the inventionThe purpose of this utility model be solve that the prior art security is low, technical problem that global blowup weak effect and being not suitable for is networked explosion, provide a kind of low power to lead quick-fried detonator, to overcome the deficiencies in the prior art.
For achieving the above object, the low power of the utility model is led quick-fried detonator, and it comprises shell; Its main points are to be provided with successively from the bottom to top main charge casing, safe initiation body, delay element, rubber stopper and detonator in described shell; The lower end of described detonator is plugged in rubber stopper.
The utility model is simple in structure, easy to use, owing to being provided with delay element, can adjust the length of delay element according to the time of networking explosion, to adapt to the needs of the explosion of networking; Simultaneously, do not contain priming in shell, power is little safe, and the fragment of blast generation is few and the fragment energy is low, can not cut and lead quick-fried blasting cap initiation network.The technical problem that the utility model has solved that the prior art security is low, global blowup weak effect and being not suitable for is networked explosion.
