The anti-prying structure comprises a buckle plate, a protection box and an anti-prying mechanism, the protection box is fixedly connected to the rear side of the buckle plate, and the buckle plate is provided with a lock hole for a latch bolt to stretch into the protection box; the anti-prying mechanism comprises a swing arm and an extending part, the swing arm is installed in the protection box in the mode that the root and the end of the swing arm can swing back and forth around the middle, the extending part is arranged in the protection box in the mode that the extending part can slide back and forth, an avoiding hole used for allowing the extending part to extend forwards out of the buckle plate is formed in the buckle plate, and a shifting groove is formed in the extending part. The end of the swing arm extends into the shifting groove, a shifting structure is arranged at the root of the swing arm, the shifting structure is used for being driven by the latch bolt to drive the root of the swing arm to swing backwards, and the end of the swing arm swings forwards to shift the extending part to extend forwards out of the buckle plate. Through reasonable arrangement of the anti-prying structure, the anti-prying function can be realized under the condition that the door is not locked, so that the safety of the door is improved.
本发明涉及一种防撬结构，包括扣板、护盒和防撬机构，护盒固定连接在扣板的后侧，扣板上设置有用于供斜舌伸入护盒内的锁孔；防撬机构包括摆臂和伸出件，摆臂以根部和端部能够绕中部前后摆动的方式安装在护盒内，伸出件以能够前后滑动的方式设置在护盒内，扣板上设置有用于供伸出件向前伸出于扣板的避让孔，伸出件上设置有拨动槽，摆臂的端部伸入拨动槽中，摆臂的根部设置有拨动结构，拨动结构用于供斜舌驱动以带动摆臂的根部向后摆动，摆臂的端部向前摆动能够拨动伸出件向前伸出于扣板。本发明通过合理设置防撬结构，在门未反锁的情况下也能够实现防撬功能，从而提升了门本身的安全性。
