The Rotary Tongue Lock is the most widely used fundamental locking solution in the field of industrial cabinets. This product features high reliability, simple structure and economic practicality as its core characteristics. The principle is that the lock core directly drives one or more lock tongues to rotate to achieve the opening and closing of the lock. It is the preferred lock for standard cabinets, control boxes, instrument panels and various sheet metal chassis.
Product positioning：
This product offers economical and reliable standardized basic security. Meet the basic locking requirements at the lowest cost.
Working principle:
The core lies in the eccentric CAM (rotating tongue) at the tail of the lock core. When the key is inserted and turned, the lock core drives this CAM to rotate 90° or 180°. During the rotation of the CAM, it will get stuck in the groove of the lock plate or lock piece installed on the door frame, thereby mechanically locking the door panel and the door frame together.
