Furthermore, because the ignition string is laid close to the case body, the ignition string is prevented from being inadvertently snagged and pulled by other objects, thus preventing an unexpected explosion of the firecracker.
The firecracker (1) explodes on the firecracker-firing support (10) to prevent an accident, and firecrackers (1) can be continuously fired on the rotation plate (60).
Provided are a firing device and a repeating firecracker- firing apparatus.
The firecracker case of the present invention comprises an insert seating means which is integrally provided in a case body (100).
Disclosed are a twin-bodied serially built-in safe and environmentally friendly firecracker and a unit thereof.
The present invention provides a fog signal device comprising a fog signal body (2) containing explosive and magnetic attachment means (6) for holding the body (2) onto a railway rail (3).
The fog signal body (2) is placed on the first layer (6) of the device (1).
The fog signal body (2) comprises a metal casing that contains explosive material.
The fog signal body (2) is naturally attracted to the magnetic device (1).
A squib (15) within the mount (12) arranged for remote ignition serves to shear the pin (14) in emergency, release the latch (17) and allow spring (21) ejection of the beacon.
A device (1) for attaching a disc shaped fog signal body (2) to a railway rail (3) comprises a first layer (6) and a second layer (8).
