Anti-disengagement U-shaped lock
A U-shaped lock for preventing a lock body from slipping comprises a U-shaped lock ring and a lock body. A lock hole is formed in the lock body. Two lock ring holes are formed in the lock body. A lock brake is arranged at each lock ring hole in the lock body. The U-shaped lock ring comprises a first straight rod and a second straight rod. The first straight rod and the second straight rod can penetrate through the lock ring holes and are each provided with a plurality of lock grooves. The lock grooves are matched with the lock brakes in the lock body. The length of the first straight rod is larger than that of the second straight rod. Due to the length of the first straight rod, it can be ensured that the lock body is separated from the second straight rod when sliding to the tail end of the first straight rod. An anti-disengagement lock device is arranged at the tail end of the first straight rod. It can be effectively avoided that when the U-shaped lock is operated, the lock ring slips from the lock body by accident and causes damage to people or a floor.
