Glass breaking device

Abstract

The invention discloses a glass breaking device which is installed at the position, close to a vertex corner of window glass, of a vehicle body. The glass breaking device comprises a base fixed to the vehicle body, a pivot seat fixed to the base and a breaking hammer. The breaking hammer comprises a handlebar which is in pivot joint with the pivot seat and pivots in the plane perpendicular to the window glass, and a pointed awl fixedly connected to the head of the handlebar and facing the window glass. The handlebar drives the pointed awl to pierce into the window glass so as to break the window glass by pivoting around the pivot seat. Due to the fact that the glass breaking device is installed at the position, close to the vertex corner of window glass, of the vehicle body, the glass breaking hammer is in pivot joint with the pivot seat through the handlebar of the glass breaking hammer, the handlebar is equivalent to a lever, and the pivot joint position of the glass breaking hammer and the handlebar of the glass breaking hammer is equivalent to the fulcrum of the lever, in the time of an emergency, a passenger only needs to pull the tail part of the handlebar with the hands, and the head of the handlebar can pivot around the pivot seat to drive the pointed awl to pierce into the window glass so as to break the window glass. The passenger can use the glass breaking device to break the glass in a congested and chaotic compartment without exerting force by swinging the arms, and operation is simple and flexible.

Description

technical field [0001] The invention relates to an escape tool, in particular to an emergency glass breaker. Background technique [0002] With the continuous improvement of living standards, passengers have continuously improved requirements for the comfort of the means of transportation used for travel.
