The invention relates to the related technical field of anti-theft doors, and discloses an anti-cutting intrusion anti-theft door chain which comprises a door frame part, a door plate part and an anti-cutting lock chain, the door frame part comprises a fixed rail, a clamping and fixing sliding block is slidably installed in the fixed rail, a supporting spring is installed on the clamping and fixing sliding block, the door plate part comprises a fixed plate, and the fixed plate is fixedly connected with the door plate part. The fixed plate is provided with a rotatable sliding connection ring, and the sliding connection ring is provided with a notch groove. According to the anti-theft door chain capable of preventing cut-off intrusion, the anti-cut-off functional structure is arranged, the door frame part and the door plate part in the anti-theft door chain structure are connected through the anti-cut-off lock chain, and the anti-cut-off lock chain is composed of a functional sheath, a supporting anti-cut layer and a lock chain body; compared with a conventional anti-theft door lock chain which is of a two-layer structure composed of a chain body and a rubber sleeve, the anti-cutting-off chain has the higher violent intrusion prevention effect.
本发明涉及防盗门相关技术领域，公开了一种防止切断闯入的防盗门锁链，包括门框部、门板部以及防切断锁链，所述门框部包括固定轨，所述固定轨内滑动安装有卡固滑块，所述卡固滑块安装有支撑弹簧，所述门板部包括固定板，所述固定板安装有可转动的滑接环，所述滑接环设有缺口槽；本发明的一种防止切断闯入的防盗门锁链通过防切断功能结构的设置，防盗门锁链结构中的门框部及门板部通过防切断锁链连接，防切断锁链由功能护套、支撑防切层、锁链三层结构构成，相较于常规防盗门锁锁链由锁链及胶套的两层结构，防切断锁链具备更强的防止暴力闯入效果。
