Window breaker

Abstract

The invention discloses a window breaker, comprising a connecting base and a driving hammer with a pointed cone. The window breaker is characterized in that: the connecting base is fixedly connected with a support base and an outer sleeve respectively; the support base is fixedly connected with the lower end of the connecting base; the upper end of the connecting base is coupled with a handle; the handle and the support base are positioned at the same side of the connecting base; the driving hammer is arranged in the outer sleeve; and a triggering mechanism is arranged between the handle and the outer sleeve for triggering the driving hammer to be downwards popped. The window breaker has the advantages that: the window breaker uses instantaneous release of spring potential energy to push the driving hammer to strike the glass so as to break the glass; when in use, the arms are not forcibly swung; a shaft joint of the handle and the connecting base, the connecting part of a handle sliding slot and an inner sleeve connecting shaft, and the applying point of the hand on the handle form a lever mechanism so that the window breaker can easily break the glass without forcibly pressing the handle; the window breaker is simple in operation, safe and reliable, and convenient for passengers to fast and effectively escape when the arms are difficult to swing.

Description

technical field [0001] The invention relates to an emergency escape tool, in particular to a window breaker. Background technique [0002] The current means of transportation (such as buses, buses, trains, etc.) are basically air-conditioned vehicles, and the windows generally cannot be opened. In order to facilitate passengers to escape when an emergency occurs, the means of transportation are basically equipped with emergency hammers. When using it, you only need to pick up the emergency hammer and swing your arm vigorously to break the window. However, when an accident occurs, many passengers cannot use the emergency hammer to use enough force when the passengers in the bus are crowded and flustered. The force smashed the window of the car; or when the car fell into the water, the passengers in the car could not swing their arms in the water, causing the people in distress to lose the chance of escape.
