Roller bolt mortise lock is a kind of embedded door lock, and its core mechanism adopts rolling lock bolt design. Different from the traditional oblique bolt lock, it reduces the friction between the locking tongue and the pinch plate through the roller or bearing structure to realize smooth locking. This kind of locks usually adapt to the thickness of European standard doors, and it is necessary to pre-unlock the lock body slots and installation holes. Its structure includes lock body, roller lock bolt, deadbolt and panel assembly, and the internal mechanism is driven by lever or key. The EN12209 standard defines its mechanical performance and durability requirements, EN1634 covering fire prevention, EN1670 corrosion prevention and EN12209 cyclic testing, so as to ensure that the basic functions meet the European building hardware regulations.
