A train escape window opened by inertial impact force

Abstract

The invention provides a train escape window opened by utilizing the inertia impact force. The train escape window opened by utilizing the inertia impact force comprises a window frame installed on atrain body, hanging plates are both fixedly connected to the top of the left side and the top of the right side of a piece of window glass, an inertia block is slidably connected to the interior of abox body, a spring is installed on a driving shaft, a ratchet wheel shaft and a movable shaft are rotationally connected to the interior of the box body, a pawl is movably arranged on the outer side of the ratchet wheel shaft in a sleeve manner, a positioning gear is fixedly connected to the outer side of a driven shaft in a sleeve manner, and a pull rod is fixedly connected to the outer side of the movable shaft in a sleeve mode. The inertial energy of the train is stored through the inertia block and the spring, the spring is prevented from releasing the energy through the pawl and the positioning gear, after a pull rod is pulled, the pawl is separated from the positioning gear, a lifting block is aligned with a positioning pin under the driving of the spring, the positioning pin is ejected out through the repulsive force between magnetic sheets, the window glass falls, the escape window is opened. the structure does not need to damage the train window, the operation is simple, theescape is rapid, and the safety is high.

Description

technical field [0001] The invention belongs to the technical field of rail transit safety, and in particular relates to a train escape window opened by inertial impact force. Background technique [0002] Escape windows are designed on rail transportation vehicles such as high-speed rail and trains, so that in the event of a traffic safety accident, passengers in the car can escape in time. At present, the escape tool commonly used on trains is a broken window hammer, and the windows are fixed On the car body, when escaping, you need to use a window breaking hammer to break the window before you can escape. [0003] There are some problems with the escape window of this structure: it is inconvenient to use the window-breaking hammer. In order to ensure the safety of the train, the window glass is relatively strong, and it requires a large force to smash it with the window-breaking hammer, and it often needs to be smashed multiple times. According to the current test result...
