Problems solved by technology
[0003] However, at the blasting site, due to factors such as the construction personnel's operating technology and the site environment, the detonating cord cannot achieve the ideal detonation effect when the nonel detonator and detonating cord are bound with tape, and even after the detonating tube detonator explodes The detonating cord cannot be detonated normally, so that there is a safety hazard

Embodiment Construction
[0020] exist figure 2 , including the detonating cord slot (1) and the nonel detonator slot (2), respectively inserting the detonating cord and the nonel detonator into the detonating cord slot and the nonel detonator slot, detonating The diameter of the cable card slot and the detonating tube card slot is slightly larger than the diameter of the detonating cord and the detonating tube detonator, and the direction of the energy-gathering hole of the detonator is directed towards the detonating cord detonation direction, and the detonating cord binding end is connected to the detonating tube detonator The distance between them should not be less than 15cm, and then use the sealing post ① and the sealing post ② on the sealing device (8) to align and insert into the sealing slot ① and the sealing slot ② respectively, insert them tightly and compact them firmly to ensure detonation The tube detonator and the detonating cord are subject to certain constraints, are not easy to shak...

The invention discloses a novel nonel detonator detonating fuse connecting device. The device comprises a nonel detonator clamping groove, a detonating fuse clamping groove, a seal clamping groove, aseal clamping column, a nonel detonator and a detonating fuse carrier; the nonel detonator clamping groove is tangential to the detonating fuse clamping groove; the nonel detonator is mounted in the nonel detonator clamping groove; the detonating fuse is mounted in the detonating fuse clamping groove; the seal clamping column is inserted in the seal clamping groove for compacting the nonel detonator and the detonating fuse; and the nonel detonator and the detonating fuse carrier can prevent the nonel detonator and the detonating fuse from falling. The device realizes normal detonation of the detonating fuse by the nonel detonator under the condition of not binding the nonel detonator and the detonating fuse by an adhesive tape, facilitates reduction of the blasting operation, and improvesthe economical benefit of engineering blasting.
Description
technical field [0001] The invention belongs to the technical field of blasting, and in particular relates to a novel nonel detonator detonating cord connection device, which enables the nonel detonator to detonate the detonating cord normally. Background technique [0002] At present, in engineering blasting, whether it is mine blasting or demolition blasting, detonating cord connection network or detonating cord-nonel connection network are often used. Whether the detonating cord can be initially detonated and detonated normally is very important. At present, in the actual blasting process, adhesive tape is often used to bind the detonator detonator and the detonating cord to a certain length and wrap it tightly, so as to ensure that the detonator detonator can be detonated and detonated by using the shock wave and fragments generated after the explosion. search. [0003] However, at the blasting site, due to factors such as the construction personnel's operating technol...
