Description

Technical Field

[0001] The invention belongs to the field of rescue equipment, and in particular relates to a window-breaking bullet launched by a drone. Background Art

[0002] When the police are arresting criminals, some criminals, when they are desperate, will hijack nearby people as hostages and hide in buildings. In the process of rescuing hostages, in order to reduce casualties and ensure the safety of hostages, rescuers are often required to rush to the criminals quickly and control them. In order to achieve the shortest distance and rapid advance, it is necessary to use window-breaking bombs to break windows. At the same time, window-breaking bombs can also play an important role in rescuing trapped people in fire scenes.

[0003] In order to ensure the effects of sound insulation and heat preservation, modern buildings usually use double-layer vacuum glass, which is difficult to break. In order to expand the glass opening, existing window-breaking bombs mostly use gunpowder. After the bullet contacts the glass, the window-breaking bullet explodes and shatters the glass. However, this type of ammunition often generates high temperatures, which is not conducive to rescuing personnel. Some window-breaking bullets also have built-in expansion mechanisms that can expand the cross-sectional area of ​​the bullet. When it contacts the glass, the expansion mechanism is triggered, which increases the cross-sectional area of ​​the bullet and expands the window breaking area. However, this type of bullet often has a complex internal structure, which is not conducive to production. Summary of the invention

[0004] In view of this, the present invention aims to provide a window-breaking bomb launched by a drone to simplify the structure of the window-breaking bomb and expand the window-breaking area.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

During use, a window-breaking bullet is launched by a drone, and the impact unit 1 at the front end of the bullet body 2 preferentially hits the window. Specifically, when the impact unit 1 initially contacts the window, the impact force of the window-breaking bullet itself and the firing pin 13 are used to destroy the contact point of the window. In this embodiment, in order to cope with thick glass or double-layer glass, the length of the firing pin 13 is not less than 10MM, so that the firing pin 13 can pierce the glass. The firing pin 13 and the impact hammer 11 are eccentrically arranged, so that when the firing pin 13 contacts the window, the center of gravity of the bullet itself deviates, and the bullet body deviates and tilts to one side, and the volume of the bullet body 2 and the impact force generated when the bullet body is launched are used to destroy the window over a large area, so as to facilitate people to enter and exit.

[0033] The warhead body 2 includes a cartridge outer wall 21, a cartridge bottom shell 23 and a primer seat 22, and the cartridge outer wall 21, the cartridge bottom shell 23, the primer seat 22 and the impact hammer 11 are coaxially arranged, the bottom of the impact hammer 11 extends vertically downward, and the top of the cartridge outer wall 21 is sleeved on the bottom of the impact hammer 11 and is interference fit with the impact hammer 11, the bottom end of the cartridge outer wall 21 is fixedly connected to the cartridge bottom shell 23, specifically, the cartridge bottom shell includes a blocking piece 233, the blocking piece 233, the cartridge outer wall 21 and the bottom end face of the impact hammer 11 surround to form a medicine cavity 211, the medicine cavity 211 is filled with a smoke agent 212, and the smoke agent 212 can be a tear gas agent, a smoke agent, an odor marking agent, etc. according to the required venue.

[0034] A first connecting ring 231 is extended upward from the edge of the upper surface of the blocking piece 233, and a plug-in stepped hole 213 is formed at the bottom end of the outer wall of the bottom shell. The first connecting ring 231 is inserted into the plug-in stepped hole 213, and the bullet bottom shell 23 and the outer wall 21 of the cartridge barrel are fixedly connected by the first connecting ring 231 and the plug-in stepped hole 213 (the fixed connection here can be an interference fit or a threaded fixed fit at the two connections); a second connecting ring 232 is extended downward from the edge of the blocking piece 233, and a ring-shaped plug-in groove 2321 is formed along the end face of the second connecting ring 232, and a plug-in edge 222 is extended upward from the top edge of the primer seat 22, and the plug-in edge 222 is inserted into the plug-in groove 2321.

[0035] A buffer cavity 24 is left between the primer seat 22 and the warhead bottom shell 23. Specifically, the buffer cavity 24 is formed by a sealing piece 233, the side wall of the second connecting ring 232 of the primer seat 22 and the side wall of the connecting edge, and a step hole 2331 is opened in the middle of the sealing piece 233. The step hole 2331 is connected with the buffer cavity 24 and the powder cavity 211. The step hole 2331 is equipped with a delay charge 25. The heat generated by the combustion of the primer gunpowder 26 heats the buffer cavity 24, thereby extending the initial combustion time of the smoke agent 212, so that the window-breaking bullet starts to burn the smoke agent 212 after breaking through the glass window, so as to avoid the substances formed by the combustion of the smoke agent 212 from polluting the outdoor air and causing danger to the surrounding people. In order to increase the buffer cavity 24, an annular groove 241 is opened on the lower surface of the sealing piece 233 along the side of the step hole 2331.
