Lifesaving device by breaking window

Abstract

The invention discloses a lifesaving device by breaking windows, comprising a case, a bracket assembly, a hammer head for breaking the window and a pair of hooks controlled by a torsional spring, wherein the case wall on the front side end of the case is provided with a through hole for a hammer head to be ejected; the lower section of the inner working chamber in the case is provided with a working slope; the bracket assembly moves back and forth along the axis; the front end of the hammer head is pointed, and the rear end is provided with a bench preventing the hook from sliding down; the middle of the hook and the torsional spring are both fixed on the fixed junction plate of the bracket; the hook shape of the hook support arm causes the hook to clamp the hammer head under the normal condition; the exterior angle on the bottom end of the hook is provided with an arc angle; and the arc angle can cause the front falcula to gradually open and loosen the hammer head when the arc angle slides down if contacting with the working slope of the lower section of the working chamber in the case. The front end of the main spring is sheathed on the rear bench of the hammer head, and the rear end is propped against on the inner wall of the case of the tail part. The lifesaving device by breaking windows can conveniently and quickly break glass windows and doors during rapid-onset disasters, such as fire hazard, earthquake, traffic accidents and the like, helps people to quickly escape from dangerous sites and protects life safety of people.

Description

technical field [0001] The invention relates to a mechanical device for lifesaving, in particular to a broken window escape device. Background technique [0002] In contemporary social life, glass has occupied many parts of life, for example: glass windows of buses, cars, glass doors and windows of modern buildings, etc. However, in the use of glass, in addition to being beautiful and practical, it also has the characteristics of easy escape in dangerous situations. However, many places in China are rarely equipped with auxiliary escape devices. The common ones are safety hammers, but the effect is not good due to the limitation of the force application space and force size. Reports of heavy casualties such as bus fires are common. Contents of the invention [0003] The object of the present invention is to provide a broken window escape device, which is safe, reliable, efficient and practical. [0004] To achieve the above object, the present invention takes the follow...
