Spiral type directional password theft-proofing ring lock
The invention provides a spiral type directional password theft-proofing ring lock. According to the design, the spiral type directional password theft-proofing ring lock is equipped with a frame; one end of a ring is firmly welded in 90 degrees to the frame, and while the other end of the ring is welded with a fixing block; the frame is connected with a side lock block; a long groove is formed in the combined surface between the side lock block and the frame; a quadrate through hole is formed in the fixing block; the long lock block is inserted into the quadrate through hole in the fixing block and the long groove in the side lock block; an upper embedded block and a lower embedded block are arranged in the frame; a plurality of through holes of which the diameters are less than the thickness of a disc are formed in the end surface of one end of the upper embedded block; a plurality of screws are arranged and respectively screw leftwards and rightwards; password numbers are etched without order on the disc; the screws are clamped between the upper embedded block and the lower embedded block with a certain clearance; when rotating the disc, the screws can move in and out of a circular blind hole in the long lock block by a rotating manner. The spiral type directional password theft-proofing ring lock has the beneficial effects that the password is set and can be replaced, so that the lock cylinder is avoided frequent replacing; the locking password and the unlocking password can be remembered simply, and thus a key can be saved; the lock is firm and wearable, resistant to prying and sawing, has the double-locking function, and is convenient, safe and reliable to use, and can be widely applied to the non-motor vehicle.
