The present invention relates to a door frame locking device for livestock, comprising: a door lock device for livestock used in the door frame to intercept the opening and closing of the barn door that is formed in the latch and bidirectionally opened, the body installed in the door frame； Intermittent plates coupled to both sides of the body so as to be rotatable in a predetermined angle and in a direction facing each other； And an elastic body coupled to be connected to each other between the intermittent plates； wherein, when the barn door is closed, the intermittent plate adjacent to the brace is opened by being pushed by the insertion of the brace, and is opened again after the brace is inserted. It is rotated by and closed to interrupt the barn door, and when the intermittent plate is rotated to open, it is characterized in that it is rotated so as to open only to the same height as the diameter of the latch by stoppers formed on each side of the body. In such a configuration, when the latch is inserted, the interruption plates are rotated only in the direction facing each other, so that the latch is naturally pushed and closed by pushing the interruption plate as the barn door is rotated, or the interruption plate in one direction is rotated upward. By pulling the latch in one direction in a state of being made to be opened by the release of the intermittent release of the barn door, it is possible to obtain an effect that can be prevented from opening the barn door arbitrarily by livestock.본 고안은 가축용 문틀 잠금장치에 관한 것으로, 걸림쇠가 형성되고 양방향으로 개폐되는 축사문의 개폐를 단속하도록 문틀에 설치된 축사용 문틀 잠금장치에 있어서, 상기 문틀에 설치된 몸체； 상기 몸체의 양측에 각각 기 설정된 각도 및 서로 마주보는 방향으로 회동 가능하게 결합된 단속판； 및 상기 단속판 사이에 서로가 연결되도록 결합된 탄성체；를 포함하고, 상기 축사문 폐쇄 시 상기 걸림쇠의 삽입에 의해 상기 걸림쇠와 인접하는 단속판이 밀려 회동되면서 개방되고 상기 걸림쇠 삽입 후 다시 탄성 및 무게 중심에 의해 회동되며 폐쇄되어 상기 축사문을 단속시키며, 상기 단속판은 개방되도록 회동 시, 상기 몸체의 양측에 각각 형성된 스토퍼에 의해 상기 걸림쇠의 직경과 동일한 높이까지만 개방되도록 회동되는 것을 특징으로 한다. 이러한 구성으로, 걸림쇠가 삽입될 때 단속판이 서로 마주하는 방향으로만 회동되도록 형성함으로써, 축사문이 회동됨에 따라 걸림쇠가 자
