Embodiment 1

[0026] Embodiment one: if figure 1 As shown in -5, the anti-theft padlock of this embodiment is mainly composed of a lock body and a U-shaped lock bar 5. The lock body includes hinged joints 1 at both ends, lock heads 2 and middle connecting rods 3 connecting the hinged joints 1 and lock heads 2 , the lock head 2 is provided with a lock cylinder 4 with a lock hole, and the two ends of the U-shaped lock rod 5 are respectively a connecting end 50 and a locking end 51, and the locking end 51 is connected with the lock hole. The rotating shaft 10 of the hollow pipe structure and the casing 11 welded on the connecting rod 3 are composed. The middle part of the rotating shaft 10 is provided with a positioning hole 100. The rotating shaft 10 is sleeved in the casing 11, and the connecting end 50 of the U-shaped locking rod 5 passes The positioning hole 100 is welded in the middle of the rotating shaft 10 afterward. In order to prevent water vapor and dust from entering the casing 11...

Embodiment 2

[0027] Embodiment two: if Figure 6 As shown, the main structure of the anti-theft padlock of this embodiment is basically the same as that of Embodiment 1, except that the rotating shaft 10 is a solid tubular structure.

Embodiment 3

[0028] Embodiment three: as Figure 7 , Figure 8 As shown, the main structure of the anti-theft padlock of this embodiment is basically the same as that of Embodiment 1, the difference is that the end cap 6 for sealing is a structure with a stepped table top, and is welded on both ends of the sleeve 11.

[0029] The connection installation scheme of the above-mentioned embodiment is as follows: firstly, the sleeve 11 is welded to the end of the middle connecting rod 3, then the rotating shaft 10 is sleeved in the sleeve 11, and then the connecting end 50 of the U-shaped locking rod 5 is positioned Hole 100 place is welded in the middle part of rotating shaft 11, if be provided with end cover 6, its end cover 6 is put on last welding. After welding, the welding point is polished.
