Plunger-type car window crushing mechanism

Abstract

The invention relates to an escaping device and in particular relates to a plunger-type car window crushing mechanism. The plunger-type car window crushing mechanism is composed of a screw, a box body, a crushing opening, a rotary shaft, a slide bar channel, a slide bar head, a rare-earth magnet, an iron pull ring, a spring, a plunger, a lubricating ring, a crushing tip, a guide strip, a slide bar, a connection hole, a steel wire rope and a rope box. The upper and lower ends of the box body are fixedly connected with a car window glass and one vertical slide bar channel is arranged in the inner part of the box body; the upper end of the slide bar channel is provided with the rectangular crushing opening, the upper half section of the guide strip is provided with the tapered crushing tip and the lower half section of the guide strip is located inside the slide bar channel. The cylindrical slide bar head is located inside the slide bar channel and a spring is sleeved on the slide bar. According to the plunger-type car window crushing mechanism, passengers can conveniently crush the car window in a long distance only by small forces, thereby achieving the aim of escaping.

Description

technical field [0001] The invention relates to an escape device, in particular to a bolt type vehicle window breaking mechanism. 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. However, such a solution has the following disadvantages: [0003] 1. 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. [0004] 2. Using a safety hammer to break tempered glass requires a certain amount of impact. When women, children or the elderly are sitting by the window of the bus, it is difficult to break the glass with enough force at one time, which will dam...

Problems solved by technology

[0003] 1. 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

[0004] 2. Using a safety hammer to break tempered glass requires a certain amount of impact. When women, children or the elderly are sitting next to the bus window, it is difficult to break the glass with sufficient force at one time, which will damage the precious delays caused by escape times

[0005] 3. When using a diamond hammer to strike the glass, since the distance between the person and the glass is relatively short, and the striking point is not blocked by any means, the splashed glass slag can easily cause injury to the operator
