Reliable and stable double-tongue lock body
The invention relates to the technical field of lock bodies, in particular to a reliable and stable double-tongue lock body which comprises a shell, an inclined tongue assembly, a square tongue assembly and a shifting fork assembly and further comprises an anti-theft assembly. The shell comprises a rear cover and a front cover, and the inclined tongue assembly comprises an inclined tongue base, aninclined tongue block, a connecting rod and a limiting plate. The anti-theft assembly comprises a telescopic channel, a push-pull channel, an anti-theft piece and a push-pull piece, the space betweenthe anti-theft piece and the push-pull piece is filled with a push-pull medium, and an anti-theft hole is formed in the inclined tongue base. By pushing the push-pull piece, the push-pull piece compresses the push-pull medium, and the push-pull medium extrudes the anti-theft piece to be ejected out of the telescopic channel and inserted into the anti-theft hole. When a hard sheet-shaped object abuts against a guide inclined face and is pushed into a door, due to the fact that the anti-theft piece is inserted into the anti-theft hole and the arrangement direction of the anti-theft piece is perpendicular to the moving direction of the inclined tongue block, the inclined tongue block cannot be pressed to retract, a door plate cannot be opened, the use safety of a lock body is improved, and potential safety hazards are reduced.
本发明涉及锁体的技术领域，尤其是涉及一种可靠稳定的双舌锁体，其包括一种可靠稳定的双舌锁体，包括壳体、斜舌组件、方舌组件和拨叉组件，还包括防盗组件，所述壳体包括后盖和前盖，斜舌组件包括斜舌座、斜舌块、连接杆和限位板，防盗组件包括伸缩道、推拉道、防盗件、推拉件，防盗件与推拉件间填充有推拉介质，斜舌座内开设有防盗孔。通过推动推拉件，推拉件压缩推拉介质，推拉介质挤压防盗件从伸缩道内弹出，并插入到防盗孔内。当硬质片状物抵接在导向斜面并向门内推动时，由于防盗件插入到防盗孔内，防盗件的设置方向与斜舌块的移动方向相垂直，因而，斜舌块无法受压回缩，门板就无法被打开，因而提高了锁体使用的安全性，减少了安全隐患。
