The invention relates to a ring lock. The ring lock is characterized by comprising a main lock, a locking pin connecting rod and locking pins, wherein the main lock is arranged at any location of the upper, lower, left or right of a door frame; the locking pin connecting rod is arranged in the door frame; the locking pins are arranged on the upper, lower, left and right surfaces of the door frame; the main lock is connected to the locking pin connecting rod which is connected to the locking pins; when the main lock is locked or unlocked, the locking pin connecting rod drives the locking pins to stretch out to a door from the four surfaces of the door frame or retract so as to control the opening and closing of the door; and a hand control switch is arranged on the main lock and is connected to the locking pin connecting rod. The ring lock completely avoids the potential safety hazards of a traditional lock caused by the fact that the locking pins of the traditional lock stretches out from three surfaces and one surface is not provided with the locking pins; the safety of the lock is greatly improved; and the ring lock is a great change of the traditional lock.
