technical field

The invention relates to the technical field of rail transit, in particular to a window breaking hammer for rail transit.

Background technique

Urban rail transit system refers to a transportation system that uses vehicles running on fixed guide rails in cities and is mainly used for urban passenger transportation. Rail transit appeared in cities as public transportation very early, playing an increasingly important role, and the economy is developed. The history of transportation development in national cities tells us that only the use of urban rail transit (subway and light rail) systems with large passenger volumes is an effective way to fundamentally improve urban public transportation conditions. Urban rail transit is a concept with a large scope. , There is no unified definition in the world. Generally speaking, urban rail transit in a broad sense refers to rail transit as the main technical feature, and is a rail transit system with a medium or more capacity in the urban public passenger transportation system (different from road Transportation), mainly for urban (different from intercity railways, but covering suburbs and urban circles) public passenger transportation services, is a modern three-dimensional transportation system that plays a key role in urban public passenger transportation.

With the development of modern science and technology, rail transit has been popularized and used in more and more cities. Window breaker is an indispensable item in rail transit vehicles. It mainly smashes glass in dangerous situations, so as to facilitate the The user escapes, and the existing window breaking hammer will be damaged after repeated use, but the existing window breaking hammer does not have the function of replacing the hammer body, so that the window breaking hammer is completely abandoned after the hammer body is damaged.
