The specific embodiment
Below in conjunction with accompanying drawing, theft proof padlock specific embodiment of the present invention is described in further detail.
embodiment one: as shown in Fig. 1-5, the theft proof padlock of the present embodiment, mainly formed by lock body and U-shape sword iron 5, lock body comprises the articulated joint 1 at two ends, the middle part connecting rod 3 of tapered end 2 and connecting hinge joint 1 and tapered end 2, be provided with the lock core 4 with lockhole in tapered end 2, the two ends of U-shape sword iron 5 are respectively link 50 and locking end 51, locking end 51 is connected with lockhole, articulated joint 1 mainly is comprised of the rotating shaft 10 of hollow tube structure and the sleeve pipe 11 that is welded on connecting rod 3, the middle part of rotating shaft 10 offers locating hole 100, rotating shaft 10 is socketed in sleeve pipe 11, the link 50 of U-shape sword iron 5 passes the middle part that is welded on rotating shaft 10 after locating hole 100.In order to prevent that steam, dust from entering in sleeve pipe 11, be preferably in the two ends interior welds end cap 6 of sleeve pipe 11.Wherein: locating hole 100 has upper end locating surface 101 and lower end locating surface 102, the anglec of rotation of the link 50 of its upper end locating surface 101 and lower end locating surface 102 restriction U-shape sword irons 5, the link 50 of U-shape sword iron 5 is vertical with middle part connecting rod 3 when arriving at upper end locating surface 101, locking bit on convenience.Angle is between the 60-120 degree preferably for the anglec of rotation of the link 50 of upper end locating surface 101 and lower end locating surface 102 restriction U-shape sword irons 5, and the anglec of rotation is too little, and U-shape sword iron 5 open angles are less, are inconvenient to lock; The anglec of rotation is too large, and U-shape sword iron 5 open angles are larger, but affects the mechanical strength of sleeve 11, and better is 90 degree, takes into account the mechanical strength of lock convenient and sleeve 11.
