Combination Lock
Exhibit Dimensions: Transport dimensions: 540×440×640mm, Display dimensions: 540×440×1450mm. Exhibit Composition: Consists of an ABS plastic molded box, ABS plastic molded base, ABS milky white plastic molded operating surface with color silk-screened flip-up instruction plate, protective cover, transmission mechanism, mechanical lock, etc. Scientific Principle: The principle demonstrated by the combination lock is the wheel mechanism. On the outside of the combination lock, there is a dial connected to the lock shaft; inside the lock, the spindle connects one driving wheel and two driven wheels. The driving wheel is equipped with a drive pin, and the driven wheels are equipped with drive plates. When the dial is rotated, the spindle turns and rotates the driving wheel, which then, through contact between the drive pin and drive plates, drives the corresponding driven wheels to rotate together, thereby changing the positions of the notches on the wheels. By dialing the correct combination, the notches on the driving wheel and driven wheels align with the linkage rod. At this point, the handle can be rotated, allowing the linkage rod to enter the notches, and the combination lock opens. Operation: Rotate the dial to adjust the positions of the notches on the three wheels; after the three notches align with the linkage rod, turn the handle to open the combination lock.
