Inclined tongue lock capable of preventing door from being opened through insertion
The latch bolt lock comprises a lock shell provided with a lock bolt opening, a shifting peach assembly and a lock bolt assembly, the lock bolt assembly comprises a latch bolt body, a bolt groove is formed in the non-inclined-face side of the latch bolt body, an anti-insertion driving bolt is hinged to the interior of the bolt groove in a swinging mode, and a stopping part matched with the inner side of the lock shell is arranged on the anti-insertion driving bolt. In the door opening state, the stopping part swings out of the bolt groove and abuts against the inner side of the lock shell to restrain the outward acting force of the shifting peach assembly so that only the latch bolt section of the latch bolt body can stretch out of the spring bolt opening, and in the door closing state, the stopping part swings into the bolt groove and leaves the inner side of the lock shell to release the outward acting force of the shifting peach assembly. When the latch bolt lock is in a door closing state, a small part of the tongue root section in the latch bolt main body extends out of the spring bolt opening, and a door slot position of the latch bolt section is replaced by the tongue root section, so that an inserting function is achieved, and the anti-theft performance of the door lock is improved.
本发明涉及防插开门的斜舌锁,包括开设有锁舌口的锁壳、拨桃组件以及锁舌组件，所述锁舌组件包括有斜舌主体，所述斜舌主体在非斜面侧开设有舌槽，所述舌槽内摆动铰接有防插驱动舌，所述防插驱动舌上设有与锁壳内侧配合的止位部，在开门状态下，所述止位部摆出舌槽外、并抵持在锁壳内侧以抑制拨桃组件的向外作用力，使所述斜舌主体仅斜舌段伸出锁舌口外，在关门状态下，所述止位部摆入舌槽内、并离开锁壳内侧以释放拨桃组件的向外作用力，使所述斜舌主体中的斜舌段和部分舌根段伸出锁舌口外，此款斜舌锁在关门状态时，使斜舌主体中的舌根段小部分伸出锁舌口外，通过舌根段替换斜舌段的门缝位置，从而起到放插作用，提高门锁的防盗性能。
