[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0021] See also Figures 1 to 4In the utility model, an anti-theft electric padlock comprises a lock head 1, two lock holes 2 are provided on the top of the lock head 1, a U-shaped lock rod 3 is slidably installed between the two lock holes 2, a lock core 4 is installed at the bottom of the lock head 1, a rotating rod 5 is fixedly installed on the top of the lock core 4, and two symmetrical grooves 6 are provided on the top of the rotating rod 5, two horizontal slide grooves 7 are provided inside the lock head 1, and balls 8 are movably installed inside the two horizontal slide grooves 7, and the grooves 6 are movably matched with the balls 8, and two lock grooves 9 are provided inside the U-shaped lock rod 3, which are respectively matched with the balls 8, an elastic mechanism 10 is installed inside the lock hole 2 on the right side, and the top of the elastic mechanism 10 is connected and matched with the U-shaped lock rod 3, and an integrally formed elastic waterproof cover 11 is installed on the outside of the U-shaped lock rod 3, and the bottom of the elastic waterproof cover 11 is snapped to the top of the lock head 1.

[0022] When the key is inserted into the lock core 4 and the lock core 4 is rotated, the rotating rod 5 is driven to rotate, so that the two grooves 6 on the rotating rod 5 are rotated 90 degrees to face the two horizontal sliding grooves 7 respectively, so that the two balls 8 can slide relative to each other. At this time, under the action of the elastic mechanism 10, the U-shaped locking rod 3 is pushed to slide up along the lock hole 2, so that the lock groove 9 is displaced and the balls 8 are pushed to move relatively to achieve unlocking. On the contrary, the U-shaped locking rod 3 is pressed downward and the rotating rod 5 is rotated to reset so that the two balls 8 are positioned with the lock groove 9 to achieve locking. At the same time, the elastic waterproof cover 11 is engaged with the lock head 1 as the U-shaped locking rod 3 descends, and the gap of the lock hole 2 is sealed to achieve waterproofing, thereby achieving the advantages of sealing the opening gap of the device, preventing rainwater from entering, preventing rust, and improving the service life of the device, solving the problem that the box body of the power equipment in the prior art is used outdoors and is often exposed to the sun and rain, and the opening gap on the lock body is large, and rainwater can easily penetrate into the interior, causing rust in the lock, affecting the use.

[0023] See also Figure 1 , wherein: the elastic mechanism 10 includes a positioning block 101, a guide column 102 and a spring 103, the outer side of the positioning block 101 is fixedly connected to the inside of the lock hole 2 on the right side, the top of the positioning block 101 is fixedly connected to the guide column 102, the top of the guide column 102 passes through the inside of the U-shaped locking rod 3 and is slidably connected thereto, and the top of the guide column 102 is elastically connected to the U-shaped locking rod 3 through the spring 103.
