Vehicle window glass crusher and application thereof

Abstract

The invention discloses a vehicle window glass crusher and application thereof. The vehicle window glass crusher comprises a bonding part, a drum part, an impacting part and a triggering part. The bonding part comprises a bonding disc and a sleeve. The bonding disc is internally provided with a through conical channel which comprises a conical part and a circular part, and the bottom face of the bonding disc is a bonding part body. The drum part comprises an inner sleeve, an outer sleeve and an elastic clamping body. A space is arranged between the inner drum and the bonding disc and internally provided with a tip-shaped body. Pressure releasing holes are formed in the portion, where the space is located, of the drum wall of the outer drum. When the vehicle window glass crusher is used, an elastic block is plugged into the elastic clamping body. A stressed part and a firing pin are separately arranged in the portions, at the two ends of a lever in the sleeve and the inner drum, of the triggering part. The firing pin directly faces the gunpowder impacting portion of the elastic block. By adoption of the vehicle window glass crusher, the kinetic energy for crushing glass comes from detonation of the elastic body, and after the safe pin is pulled out, a user can easily excite through only a small amount of power, and the survival requirements of the groups such as children and old people are met.

Description

technical field [0001] The invention relates to the technical field of safety hammers, in particular to a window-breaking tool used on sealed glass windows with an escape function Background technique [0002] In order to improve the comfort of riding, public transport vehicles such as subway trains, high-speed trains, urban rail transit trains and buses generally use sealed glass windows.
