U-shaped groove mechanical lock and key
The lock comprises a lock body, a lock cylinder, a ring piece and a bolt pin, the end face of the inner circumference of the ring piece is provided with a convex poking connection key bit, the end face of the outer circumference of the ring piece is provided with a U-shaped groove, the U-shaped groove is correspondingly connected with the bolt pin, the ring piece is continuously arranged on the lock cylinder, and the bolt pin is arranged on the lock cylinder and is connected with the lock body and the ring piece. A main body of the key is a cylinder, a concave opening is formed in the end face of the front portion of the key and connected with an axial through groove, and annular concave and convex tooth patterns corresponding to all the annular sheet convex pokes in a one-to-one mode are arranged on the end face, connected with one side of the through groove, of the cylinder. The lock is simple in structure, if the number of the ring pieces is 22, the number of secret keys is 45, n = 22, and the number (about) of the secret keys is 25.646059 billion billion, namely, the probability of unlocking the lock continuously for 1 hundreds of millions of years is at least one of 25.646059 billion by calculation of about 31500000 seconds and three decoding per second in one year, and most importantly, no technical skillful possibility exists.
本申请为一种门锁、车锁等的U形槽机械锁及鈅匙，锁包括锁体、锁芯、环片、销栓，环片内周端面设凸拨连接钥匙牙花，在外周端面设U形凹槽、|_/形凹槽对应连接销栓，环片连续设置于锁芯，销栓设置于锁芯，连接锁体和环片。钥匙的主体为圆柱体，前部端面设有凹状开口并连接轴向通槽，在与通槽的一侧连接的圆柱体端面上，设有与所有环片凸拨一一对应的呈环向的凹、凸状牙花。本锁结构简单，若设置环片为22片的话，则秘钥量=45ⁿ,n=22，秘钥量（约）=25.646059亿亿亿亿亿，也即是以一年约31500000秒，每秒解码三个计算，则连续1亿亿年解开锁的概率至少是25.646059亿分之一，而最关键的是，没有技术性取巧的任何可能性。
