U-shaped knob type directional coded antitheft lock
The invention provides a U-shaped knob type directional coded antitheft lock. The antitheft lock is designed with a frame which is cuboid-shaped and hollow; 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 so that the frame connected with the cross beam can be turned inwards; an upper fixed block, a lower fixed block and inner inserts are arranged in the frame; a plurality of knob holes are formed in the end face of the upper fixed block; knobs are embedded into the knob holes and connected with circular rods; 5 small projections are distributed on the peripheral part of a cylinder without a blank portion; each small projection is so long that the knob can be turned to the long groove of the joint surface of the left end of the U-shaped ring and goes into the long groove by about 3mm. Digitals are formed on the knobs in the circumferential direction; a transverse line mark corresponding to the position of each knob is formed on the plane of the upper fixed block close to the digitals on the circumferential surface of the knob. The U-shaped knob type 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.
