Window breaking device

Abstract

The invention discloses a window breaker, which comprises a base part provided with a through hole and a rotating shaft seat, an elastic striking part provided with a shrapnel and a pointed cone-shaped striking head, and a wrench part provided with a dial tongue and a rotating shaft seat. One end of the base component is fixedly connected to one end of the elastic impact component, and the other end is connected to the wrench component through a rotating shaft mechanism; the other end of the elastic impact component is fixed with a pointed cone-shaped impact head; the dial of the wrench component The tongue hooks one end of the elastic impact part with the impact head. When the window breaker of the present invention is activated, the handle of the wrench part is pulled, and the wrench part rotates relative to the base part through the rotating shaft. When one end reaches a certain angle, the two are separated, and the potential energy generated during the separation drives the impact head to quickly strike the glass piece through the through hole of the base component and break the glass piece.

Description

technical field [0001] The invention relates to a window breaker, which is mainly applicable to the needs of rapid window breaking for emergency evacuation and escape in various places and vehicles. Background technique [0002] At present, in places such as various entertainment venues, airports, stations, various vehicles, especially public transport vehicles with high density of people, etc., the window breaking tools used for emergency evacuation and escape are mainly safety hammers. The probability of carrying a safety hammer with you is very small. If a public safety hammer encounters an emergency that needs to break a window, you need to go to a designated place to remove it. Moreover, this kind of safety hammer is easy to lose, and it is limited by the environmental space and users. Big, such as minors, especially the old, weak, sick and disabled, are more unable to operate and use. [0003] And some existing patented technologies are either complicated in structure...

Problems solved by technology

The probability of carrying a safety hammer with you is very small. If a public safety hammer encounters an emergency that needs to break a window, you need to go to a designated place to remove it. Moreover, this kind of safety hammer is easy to lose, and it is limited by the environmental space and users. Large, such as minors, especially the elderly, weak, sick and disabled, are more unable to operate and use

[0003] And some existing patented technologies are either complicated in structure or difficult to operate, and misoperation may also occur; some design electronically controlled window breakers, but when encountering emergencies, the power supply must be turned off at first according to the operation process, so that It will cause the failure of the electronically controlled window breaker, and the circuit and electrical appliances are prone to failure and the reliability is not strong, which is not conducive to popularization
