Hand-knocking-type window glass breaking device

Abstract

The invention relates to a window glass breaking escape device, in particular to a hand-knocking-type window glass breaking device. According to a window glass emergency hammer used at present, the defects that the requirement for a knocking position is high, and the allocation quantity is small exist, the requirement for passenger emergent escape cannot be met, and the escape opportunity is delayed. In order to overcome the defects existing in the emergency hammer for a vehicle at present, the hand-knocking-type window glass breaking device is provided and composed of a hard metal plate (1), a sponge ring (2) and an annular gasket (3), wherein the center of the hard metal plate (1) is provided with a sharp tooth, and the sponge ring is respectively connected with the sharp tooth face of the metal plate and the annular gasket through glue. When used, the hand-knocking-type window glass breaking device just needs to be stuck to the portion, close to a window corner, of glass (5) through double faced adhesive tape. When in danger, passengers just need to manually knock the metal plate (1) with strength, the sponge ring (2) between the metal plate and the annular gasket will be compressed to deform, the sharp tooth (4) in the center of the metal plate generates large pressure intensity on the window glass (5), and therefore the purpose of breaking the window glass to escape is achieved. The hand-knocking-type window glass breaking device is applicable to various vehicles, and particularly applicable to a large bus.

Description

Technical field: [0001] The invention relates to a vehicle window glass cracking device, which is especially suitable for breaking the vehicle window glass to escape when various large passenger cars are in distress. Background technique: [0002] At present, traffic accidents occur frequently in various parts of our country, especially large passenger cars, because the window glass cannot be opened, and they cannot escape in time, causing many casualties. The tragedy of the disaster is shocking. At present, although the relevant departments mandate that large passenger cars must be equipped with safety hammers for knocking on the window glass, due to the high requirements for the knocking position, the small number of configurations, and the easy loss, etc., it often cannot meet the needs of emergency escape, thus delaying The timing of escape caused a large number of casualties. Invention content: [0003] In order to overcome the shortcomings and deficiencies existing ...
