U-shaped spiral directional coded antitheft lock
The invention provides a U-shaped spiral directional coded antitheft lock. The antitheft lock is designed with a frame which is cuboid-shaped and hollow; a groove is formed in the revere side of the lower end of the frame; the frame is firmly welded at 90 degrees with one end of a cross beam; the other end of the cross beam is clamped in the right upper end of a U-shaped ring and connected by use of a rotating pin; a circular blind hole is formed on the left end side of the U-shaped ring and the diameter of the circular blind hole is slightly greater than the diameter of a screw. An upper fixed block and inner inserts are arranged in the frame; a plurality of through holes are formed in the end face of one end of the upper fixed block, and the diameter of each through hole is smaller than the thickness of a disc or the travel distance of one through hole is about 3mm; a plurality of left-handed and right-handed screws are arranged; code digitals are formed on the disc and can be arranged not in order; the screws also are clamped between the inner inserts with a certain gap; when the disc is rotated, the screws can be rotatably pushed into or pulled out of circular blind holes formed in the left end of the U-shaped ring. The U-shaped spiral directional coded antitheft lock is provided with changeable codes and a lock cylinder which does not need to be changed frequently; no key is needed and only locking codes and unlocking codes need to be remembered; the anti-theft lock can be widely applied to non-motor vehicles.
