Embodiment Construction

[0020] as attached figure 1 As shown, the present invention provides a deformable energy-gathering cutting device for breaking grids. The cutting device is mainly composed of two action units 3 with metal drug-type covers embedded in the inner charges. The two action units 3 The two are connected through the explosion transmission sequence 2, and the action unit 3 is fixedly connected to the fence vertical bar 4 and the fence cross bar 5 at the site where the fence bar needs to be demolished through the elastic ferrule; the detonator 1 is installed on an action unit 3, and the detonator 1 receives the external detonation signal and transmits the detonation signal to another action unit 3 through the detonation transmission sequence 2, so that the explosives 9 in the two action units are detonated synchronously, and the energy generated by the explosives makes the metal liner 8 form a metal jet to The part of the fence that needs to be demolished is cut and destroyed.

Abstract

The invention discloses a deformable energy-gathering cutting device for grid breaking, which belongs to the technical field of ammunition. The cutting device includes two action units, an explosion transfer sequence, a detonator and an elastic ferrule; the two action units are connected through an explosion transfer sequence, and the action unit is connected to the fence bar through an elastic ferrule fixed to itself; The detonator described above is installed on one action unit, and the detonator receives an external detonation signal and transmits the detonation signal to another action unit through the detonation transmission sequence, so that the explosives in the two action units are detonated synchronously, and the energy generated by the explosive is realized on the fence. Cut damage. The invention uses the energy-gathering effect of the charge to realize cutting and destroying the fence. The device can not only cut the fence bars on both sides separately, but also cut the opposite side or the same side of a certain fence bar, so as to realize the rapid and efficient demolition of the fence gate. .

Description

technical field [0001] The invention relates to a deformable energy-gathering cutting device for quickly dismantling a fence, and belongs to the technical field of ammunition. Background technique [0002] Anti-theft nets and fence doors are not uncommon in our daily life, especially in the outer windows of buildings and the entrances and exits of residential quarters. With the improvement of people's requirements for architectural aesthetics, fence doors with more decorative and fashionable effects emerge in an endless stream on the market, and have been widely used in hotels, hotels, leisure and entertainment centers, apartment houses and other places. Although anti-theft nets and fence doors bring certain safety guarantees to residents' lives, they will become disadvantages in some cases. Anti-theft nets and fence gates just hinder the escape of personnel, and such tragedies have just happened in many cases. Simultaneously because there are many manufacturers producing ...
