Anti-theft door lock
The invention belongs to the technical field of door locks, and particularly relates to an anti-theft door lock which comprises a lock body and a lock cylinder, a marble is slidably connected between the lock body and the lock cylinder, a key hole is formed in the lock cylinder, a limiting cavity is formed in the position, close to the key hole, of the lock cylinder, and a U-shaped block is slidably connected into the limiting cavity. A first spring is fixedly connected between the side, away from the key hole, of the U-shaped block and the inner wall of the limiting cavity, the top and the bottom of the U-shaped block both extend into the key hole, a limiting groove is formed in the marble, and the limiting groove is matched with the top of the U-shaped block; by arranging the U-shaped block, an unlocking person is difficult to complete unlocking through an iron wire, when unlocking is conducted through a key, the anti-theft performance of the pin tumbler lock is improved on the premise that the unlocking step is not added, the pin tumbler lock is difficult to open without the key, and the possibility of property loss of a user is reduced.
本发明属于门锁技术领域，具体的说是一种防盗门锁，包括锁体和锁芯，所述锁体和锁芯之间滑动连接有弹子，所述锁芯上开设有钥匙孔，所述锁芯靠近钥匙孔处开设有限位腔，所述限位腔内滑动连接有U型块，所述U型块远离钥匙孔的一侧与限位腔的内壁之间固连有一号弹簧，所述U型块的顶部和底部均延伸至钥匙孔内，所述弹子上开设有限位槽，所述限位槽与U型块的顶部相适配；本发明通过设置U型块，使得开锁者难以通过铁丝完成解锁，通过钥匙进行解锁时，在没有增加开锁步骤的前提下提高弹子锁的防盗性能，难以在没有钥匙时打开弹子锁，降低使用者财物损失的可能性。
