Spring bolt linkage mechanism and anti-theft door lock
The invention discloses a spring bolt linkage mechanism and an anti-theft door lock, and relates to the technical field of locks.The spring bolt linkage mechanism comprises a shell elastically connected with a spring bolt, the interior of the shell is further elastically connected with an auxiliary bolt through an auxiliary bolt base, the spring bolt and the auxiliary bolt form a protruding block and a clamping block which correspond to each other, and the spring bolt is clamped by the clamping block in the normal state; only part of the spring bolt extends out of the spring bolt groove of the shell; when the auxiliary tongue relieves limitation of the spring bolt due to pressing, the spring bolt can completely stretch out of the spring bolt groove, and a locking plate arranged on the shell can lock and position the spring bolt. Compared with the prior art, the lock tongue has the first-stage limiting state and the second-stage limiting state which can be automatically switched, the opening and closing smoothness of the anti-theft door can be improved through first-stage limiting, and the anti-theft safety of the anti-theft door can be improved through second-stage limiting.
本发明公开了一种锁舌联动机构及防盗门锁，涉及锁具技术领域，锁舌联动机构包括弹性连接有锁舌的壳体，所述壳体内还通过副舌座弹性连接有副舌，锁舌与副舌彼此形成有对应的凸块和卡块，所述锁舌常态下受卡块卡止，使得自身仅有部分从壳体的锁舌槽伸出；当所述副舌因按压解除锁舌的限制时，锁舌可从锁舌槽完全伸出，壳体所设锁止板能够将锁舌锁止定位。与现有技术相比，本设计锁舌具有可自动切换的一、二级限位状态，一级限位能够提升防盗门的启闭流畅性，二级限位能够提升防盗门的防盗安全性。
