The present invention relates to a crime prevention locking bracket for a crescent which is installed on a door frame to lock and release crescent wings. At this time, in the crime prevention locking bracket for the crescent, due to a narrow space of equal to or less than 8mm between door frames, a 'U'-shaped locking groove structure of a locking bracket, which has a limit in thickness expansion, has been improved, and excellent security performance is exhibited against a forced opening force of a high load. In addition, in particular, even if a locking blade is point-contacted by a 'U'-shaped reinforcing unit, and the crescent and a ring unit are formed and constructed with a restrained binding tolerance, a frictional resistance is reduced by point contact. Because of this, in order that a user can operate the crime prevention locking bracket for the crescent without much force, a main configuration of the crime prevention locking bracket for the crescent of the present invention comprises: a fastening plate unit (10); a connecting plate unit (20); a ring unit (30); and a 'U'-shaped reinforcement unit (38).
본 발명은 문틀에 설치되어 크리센트 날개와 잠금, 해제되도록 구비되는 크리센트용 방범 록킹브라켓에 관련되며, 이때 크리센트용 방범 록킹브라켓은 문틀 사이의 문틀 사이의 8mm 이하 좁은 공간으로 인해 두께 확장에 한계가 있는 록킹브라켓의 'U'자형 걸림홈 구조를 개선하여 고하중의 강제 개방력에 대해 우수한 방범 성능을 발휘되고, 특히 걸림날개가 'U'자형 보강부에 의해 점 접촉되어 크리센트와 고리부가 억지 결속 공차로 형성 및 시공되더라도 점 접촉에 의해 마찰저항이 감소되고, 이로 인해 사용자가 큰 힘을 들이지 않고 조작할 수 있도록 체결판부(10), 연결판부(20), 고리부(30), 'U'자형 보강부(38)를 포함하여 주요구성으로 이루어진다.
