Fragile safety glass

Abstract

The invention relates to glass, in particular to fragile safety glass consisting of armoured glass and a V-shaped groove. The armoured glass is 5mm in thickness; the vertex angle of the cross sectionof the V-shaped groove is no more than 60 degrees; corresponding V-shaped grooves are arranged on the same position of double sides of the armoured glass; the distance between the vertexes of the twoV-shaped grooves at double sides of the armoured glass is no less than 2.5 mm; the V-shaped groove forms a closed star shape with an acute angle; and the star shape formed by the V-shaped groove is located at the left and right corners of the armoured glass. The invention greatly improves the reliability of the escape passage of windows.

Description

technical field [0001] The present invention relates to a kind of glass, especially relates to a kind of brittle safety glass. Background technique [0002] Existing glass that is used for bus window is mostly toughened glass, and intensity is very big. In the event of an emergency such as a fire in the vehicle body, it is very difficult to break the glass. For this reason, a diamond hammer is equipped in the bus to smash the window glass in an emergency. But in fact, because there is no special person to manage, the diamond hammers in most existing buses are stolen by thieves, so that when a fire breaks out, the passengers in the bus cannot break the glass to escape. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a fragile safety glass that can be broken by passengers in an emergency without being struck by a diamond hammer. [0004] The solution to the technical problem of the present invention is...
