[0026] The barge shaft 15 is arranged between the long rod section 8 and the short rod section 12, the short lock hole 13 is connected to the barge shaft cavity 18, a first clamping groove 16 is provided on the outer peripheral surface of the barge shaft 15, a notch 30 is provided on the groove wall of the first clamping groove 16 away from the lock core 3, and a second clamping groove 14 is provided on the end of the short rod section 12 away from the long rod section 8.

[0027] The groove wall of the second groove 14 close to the lock core 3 can be plugged into the first groove 16 of the shaft 15 located at the locking angle, and the groove wall of the second groove 14 close to the lock core 3 can be detached from the shaft 15 from the notch 30 of the shaft 15 located at the unlocking angle.

[0028] Specifically, the lock core 3 drives the dock shaft 15 to switch between a locking angle and an unlocking angle. When the dock shaft 15 is at the locking angle, the groove wall of the second slot 14 close to the lock core 3 is inserted into the first slot 16 on the short rod section 12 of the lock beam 7. The groove wall of the first slot 16 can stop the groove wall of the second slot 14 to lock the short rod section 12 in the short lock hole 13, thereby limiting the displacement of the lock beam 7. When the dock shaft 15 is at the unlocking angle, the groove wall of the first slot 16 no longer blocks the groove wall of the second slot 14, and the groove wall of the second slot 14 can detach from the notch 30, thereby achieving the unlocking of the short rod section 12.

[0029] In one embodiment, the padlock also includes a ball 29, a channel 17 connected to the barge shaft cavity 18 is provided in the shell 1, and the ball 29 is installed in the channel 17.

[0046] The working principle of the padlock of the utility model embodiment is as follows:

[0047] When it is necessary to unlock the padlock, the key 6 is inserted into the keyhole 5 of the lock core 4 and the key 6 is turned to rotate the lock core 4, thereby causing the lock core 4 to drive the shaft 15 to rotate to the unlocking angle, so that the groove 27 on the outer circumferential surface of the shaft 15 faces the channel 17. At this time, the ball 29 in the channel 17 will roll toward the groove 27. At this time, the ball 29 will disengage from the lock groove 10 on the long rod section 8, and the ball 29 loses its blocking effect on the long rod section 8, so that the long rod section 8 can move in the long lock hole 9. At the same time, the notch 30 on the outer circumferential surface of the shaft 15 faces the second slot 14, and the notch 30 is arranged on the long slot wall of the first slot 16. The upper slot wall of the first slot 16 on the long rod section 8 no longer blocks the lower slot wall of the second slot 14. When the lock beam 7 is lifted, the long rod section 8 moves up in the long lock hole 9, and the bottom end of the short rod section 12 escapes from the short lock hole 13, thereby unlocking the padlock.

[0048] When it is necessary to lock the padlock, the lock beam 7 is pressed down, the long rod section 8 moves down in the long lock hole 9, and the bottom end of the short rod section 12 enters the short lock hole 13. Then the key 6 is turned to rotate the lock core 4, and the lock core 4 drives the barge shaft 15 to rotate to the locking angle. The upper groove wall of the first groove 16 on the outer circumference of the barge shaft 15 moves to above the lower groove wall of the second groove 14, and the short rod section 12 is stopped again. During the rotation process, the ball 29 will gradually fall out of the groove 27, and the outer circumference of the barge shaft 15 will drive the ball 29 to move toward the long rod section 8 in the channel 17, so that the ball 29 is installed in the lock groove 10 of the long rod section 8, thereby locking the long rod section 8.

[0049] According to the padlock of the embodiment of the utility model, when the dock shaft 15 is at a locking angle, the groove wall of the second slot 14 close to the lock core 3 is inserted into the first slot 16 on the short rod section 12 of the lock beam 7, and the groove wall of the first slot 16 can stop the groove wall of the second slot 14 to lock the short rod section 12 in the short lock hole 13, thereby limiting the displacement of the lock beam 7. When the dock shaft 15 is at an unlocking angle, the groove wall of the first slot 16 no longer blocks the groove wall of the second slot 14, and the groove wall of the second slot 14 can be detached from the notch 30, thereby realizing the unlocking of the short rod section 12. Compared with the prior art, the number of balls 29 is reduced, the structure is simplified, and assembly is convenient.
