Abstract
A pneumatic motor vehicle window breaking device used in vehicles, comprising: a cylinder and a spike, wherein one end of the spike is fixedly connected to an end of a piston rod of the cylinder, and the other end of the spike is tapered; the cylinder is mounted on a retaining frame. The pneumatic motor vehicle window breaking device directly uses the cylinder and takes high-pressure air as power; only a front end of the spike of the pneumatic motor vehicle window breaking device is required to be mounted at an appropriate position in alignment with a vehicle window before use, and an air valve controls high-pressure air source to drive the spike to complete window breaking, and the device employs a simple structure.
Claims5
A pneumatic motor vehicle window breaking device, comprising a cylinder and a spike, one end of the spike being fixedly connected to an end of a piston rod of the cylinder, another end of the spike being tapered;
- wherein the cylinder is slidably mounted on a retaining frame in a direction corresponding to movement of the piston rod of the cylinder;
- the pneumatic motor vehicle window breaking device further comprises an elastic return structure, and the elastic return structure enables the tapered end of the spike of the pneumatic motor vehicle window breaking device when in a waiting state won't get into contact with a window;
- the retaining frame is provided with at least two guide posts in a direction corresponding to movement of the piston rod of the cylinder, a coil spring is fitted on each of the guide posts, the cylinder is formed with guide holes corresponding to the guide posts, the cylinder is slidably mounted on the retaining frame by clearance fit through the guide holes and the guide posts, and the coil spring constitutes the elastic return structure.
