Single-unlocking and double-unlocking switchable lock body
A single-unlocking and double-unlocking switchable lock body comprises a spring bolt, a shell, a linkage plate, an inner cam and an outer cam, and the spring bolt can move relative to the shell under the action of external force to complete the locking and unlocking processes; other parts can be directly or indirectly mounted, positioned or limited in the shell, the inner cam and the outer cam are fixed on the shell in a manner of rotating relative to the shell, and the inner cam and the outer cam are provided with structures capable of being in transmission with the handle or are directly fixed together with the handle, so that the corresponding inner cam or outer cam can be rotated by rotating the inner handle or the outer handle. By means of the design, function switching can be achieved on the mechanical lock, unlocking of the handles on the two sides can be switched to unlocking of the handle on the single side, unlocking of the handle on the inner side can be switched to unlocking of the handle on the outer side, and the mechanical lock can be popularized and used in many fields.
一种单开双开可切换的锁体，包括锁舌、壳体、联动板、内凸轮和外凸轮，锁舌在外力作用下可相对壳体移动完成上锁和解锁过程；壳体内可直接或间接安装、定位或限位其他零部件，内凸轮和外凸轮以可相对壳体转动的方式固定在壳体上，内凸轮和外凸轮设有可与把手传动的结构或直接和把手固定到一起使得转动内把手或外把手可以转动相应的内凸轮或外凸轮。这样设计可以在机械锁上实现功能切换，可以从两侧把手开锁切换到单侧把手开锁，可以从内把手开锁切换到外把手开锁，可以在很多领域推广使用。
