[0022] like Figure 1 As shown in FIG. 4 , the durable mechanical padlock comprises a lock body 1, wherein the outer end of the lock body 1 is sleeved with a locking outer frame 5, the rear end of the locking outer frame 5 is fixedly connected with an electromagnetic outer sheet 6, the electromagnetic outer sheet 6 is externally connected with a control terminal, the rear end of the locking outer frame 5 contacts with a matching outer plate 7, the end of the matching outer plate 7 away from the locking outer frame 5 is fixedly connected with a rubber surface adhesive layer 9, the rubber surface adhesive layer 9 is adhesively connected with a mounting base surface, the end of the matching outer plate 7 close to the locking outer frame 5 is fixedly connected with a strong magnetic surface layer 8, the strong magnetic surface layer 8 is magnetically connected to the electromagnetic outer sheet 6, and the left and right ends of the lock body 1 are fixedly connected with an additional side plate 12.

[0023] The two additional side plates 12 are symmetrically arranged, and one end of the additional side plate 12 away from the lock body 1 is fixedly connected with a locking vertical bar 2 .

[0024] The left and right inner walls of the locking outer frame 5 are symmetrically provided with protruding blocks 11 , and the upper inner wall of the protruding blocks 11 is fixedly connected with the inner slot 3 .

[0025] A protruding ball 4 is fixedly connected to one end of the engaging vertical bar 2 close to the protruding block 11 , and the protruding ball 4 is located below the engaging vertical bar 2 .

[0026] The two inner grooves 3 are located directly above the corresponding protruding balls 4 , and the two inner grooves 3 and the protruding balls 4 cooperate with each other.

[0027] The upper end of the lock body 1 is rotatably connected to a padlock U-shaped lock beam 10 , and a locking hole 13 is provided at the upper end of the lock body 1 .

[0028] The U-shaped lock beam 10 of the padlock is engaged with the locking hole 13 , and a lock ring is externally connected to the lock body 1 .
