Description

Escape window of bus

Technical Field

The invention belongs to the technical field of escape windows of buses, and particularly relates to an escape window of a bus.

Background

The bus escape is a topic of people, and in the process of taking a bus to learn, videos and methods about how to quickly escape under the condition of a fire are often played in a vehicle-mounted television of the bus. The first type of escape mode includes two types, namely, a window breaking escape mode, namely, a safety hammer is used for breaking window glass, the window is broken through the safety hammer, the safety hammer needs to be used correctly, and the correct use method of the safety hammer is as follows: when the automobile safety hammer is used, the four fingers are required to be closed together to hold the handle, and the thumb is tightly attached to the middle finger. The glass is held tightly, the hand cannot shake, and then one of four corners of the glass is knocked with force because the weakest parts of the toughened glass are the four corners. However, after a fire happens, it is difficult for a passenger to use the safety hammer correctly in a hurry, for example, the tip of the safety hammer cannot be perpendicular to a stress point of the glass effectively, both hands shake, and force cannot be exerted effectively, so that window breaking failure is caused, a large potential safety hazard exists, and after the window is broken by using the safety hammer, the window frame may have more glass fragments, and when the passenger passes through the window, the passenger is easily scratched by the glass fragments.

The second escape mode is fleed from front door or back door, usually, is provided with in front door or back door position and opens the knob, can realize quick the fleing through the knob, and the knob is rotatory back, can open the door body, realizes quick the fleing. However, sometimes the fire position is close to the front door and the rear door, under the condition of large fire, people are difficult to access the rotary switch, and in case of fire, people instinctively withdraw towards the rear part of the carriage, so that the escape from the front door and the rear door also has some potential safety hazards.

Therefore, the invention is necessary to provide a bus window capable of being opened quickly to form an escape passage.

Disclosure of Invention

The purpose of the invention is: the bus escape window can be separated from the door frame quickly to form an escape passage, and the method for separating the window from the door frame is diversified, so that the actual requirements are met.
