Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to the attached Figure 1 - attached Figure 6 As an embodiment provided by the present utility model: an automatic double-latching fixed structure for an electronic padlock, which includes a housing 8. A bracket 21 is fixedly connected inside the housing 8. A second installation groove 17 and a fifth installation groove 20 are provided on the bracket 21. A motor 7 is fixedly connected inside the second installation groove 17. The output end of the motor 7 is fixedly connected with a first transmission block 3. A connecting shaft 14 is fixedly connected inside the fifth installation groove 20. A second transmission block 9, a mounting seat 13, and a torsion spring 12 are sleeved on the connecting shaft 14, and the torsion spring 12 is fixedly connected inside the mounting seat 13. A second card slot 10 is provided on the mounting seat 13. A first installation groove 16 is provided on the bracket 21. A spring 6 is fixedly connected inside the first installation groove 16. A lock beam 1 is sleeved on the spring 6. A first card slot 2 is provided on the lock beam 1. The spring 6 is used to rebound the lock beam 1. A fourth installation groove 19 is provided on the bracket 21. One end of the torsion spring 12 is fixedly connected inside the fourth installation groove 19. The torsion spring 12 is used to drive the mounting seat 13 to rotate. A third installation groove 18 is provided on the bracket 21. A steel ball 11 is provided on the third installation groove 18, and the steel ball 11 is arranged between the first card slot 2 and the second card slot 10. The steel ball 11 is used to clamp the first card slot 2 and the second card slot 10. A buckle 4 is fixedly connected to the inner wall of one side of the housing 8. An anti-slip groove 15 is provided on the outer wall of one side of the housing 8. The housing 8 is used to install the bracket 21. A mounting plate 22 is clamped to one side of the housing 8. A second screw hole 23 is provided on the mounting plate 22. The second screw hole 23 is used to fix the mounting plate 22. A first screw hole 5 is provided on the bracket 21. The first screw hole 5 is used to fix the mounting plate 22.

[0023] Working principle: When using this utility model, it is necessary to first press the lock beam 1. When the lock beam 1 is pressed, the first card slot 2 reaches the specified position. The torsion spring 12 in the fourth installation slot 19 pulls the mounting seat 13. When the mounting seat 13 is pulled, the second card slot 10 will squeeze the steel ball 11. By squeezing the steel ball 11, the steel ball 11 enters the first card slot 2. When the pressing of the lock beam 1 stops, the spring 6 in the first installation slot 16 pushes the lock beam 1 upwards tightly to make the lock beam 1 rise. When the lock beam 1 rises, it will make the steel ball 11 clamp the first card slot 2. After the first card slot 2 is clamped, the lock beam 1 stops rising, so that this utility model achieves the purpose of locking. When it is necessary to unlock this utility model, start the motor 7 in the second installation slot 17 to make the motor 7 drive the first transmission block 3 to rotate. When the first transmission block 3 rotates, it will drive the second transmission block 9 on the connecting shaft 14. The second transmission block 9 drives the mounting seat 13 to make the second installation slot 17 rotate to the specified position. When the second installation slot 17 rotates to the specified position, the spring 6 pushes the lock beam 1 upwards tightly to make the lock beam 1 rise. When the lock beam 1 rises, it will make the first card slot 2 squeeze the steel ball 11. When the steel ball 11 is squeezed, it will move into the second card slot 10 through the third installation slot 18 on the bracket 21 and clamp the second card slot 10, so that the torsion spring 12 stops pulling the mounting seat 13, achieving the purpose of unlocking; wherein the outer shell 8 is used to install the anti-slip groove 15, the buckle 4 and the mounting plate 22. The first screw hole 5 is used to cooperate with the second screw hole 23 to fix the mounting plate 22. The fifth installation slot 20 is used to install the connecting shaft 14.
