The first locking hole 110 has a first end located on the first surface S1 and a second end remote from the first surface S1, as shown in fig. 1, and the code assembly 300 further includes a first plug 330.

Fig. 10 is a schematic perspective exploded view of a first plug in an embodiment of a padlock of the present utility model, a first plug 330 is disposed at a first end of a first lock hole 110, a receiving cavity 333 is formed in the first plug 330, a first plug groove 331 and a second plug groove 332 that are communicated with the receiving cavity 333 are disposed on a side of the first plug 330 facing the first lock hole 110, and the second plug groove 332 is not overlapped with the first plug groove 331.

Fig. 11 and 12 are schematic cross-sectional views of different cross-sections of an embodiment of a padlock according to the present utility model when modifying a combination. Referring to fig. 6, 11 and 12, when the padlock is in an unlocked state, the latch hook protrusion 211 overlaps the first plug recess 331, and the latch hook 200 can rotate around the first latch rod 210, so that the latch hook 200 rotates until the latch hook protrusion 211 overlaps the second plug recess 332, the latch hook protrusion 211 does not overlap the rotating shaft barrel recess 311, and an external force presses the latch hook 200 to push the rotating shaft barrel 310 to axially move along the first latch hole 110 after passing through the second plug recess 332, so that the rotating shaft barrel 310 is separated from the code disc 320, and the rotating shaft barrel protrusion 312 is separated from the inner peripheral recess 321, and at this time, the code disc 320 can rotate relative to the rotating shaft barrel 310 to modify the code. After the password disc 320 is rotated to a new password to be changed, the external force is removed, and the rotating shaft cylinder 310 and the locking hook 200 can axially move along the first locking hole 110, so that the rotating shaft cylinder protrusion 312 enters the reassigned inner circumferential groove 321, thereby completing the password changing operation.

The relative positions of the first plug recess 331 and the second plug recess 332 may be set according to actual needs. In this embodiment, the first plug groove 331 and the second plug groove 332 are disposed opposite to each other with respect to the central axis of the first lock hole 110, so that after unlocking the padlock, the lock hook 200 pops up, and after the lock hook 200 needs to be rotated 180 ° around the first lock lever 210, the lock hook 200 is pressed, and the lock hook protrusion 211 can smoothly pass through the second plug groove 332, so as to realize subsequent password modification operation of the password component 300.

In some embodiments, as shown in fig. 7, a lock body groove 111 is provided on the inner periphery of the first lock hole 110. When the combination assembly 300 is in the correct combination state, the rotary shaft barrel protrusion 312 overlaps the lock body groove 111, the rotary shaft barrel protrusion 312 can enter and exit the lock body groove 111, and the rotary shaft barrel 310 is axially movable along the first lock hole 110. In the password error state of the password assembly 300, the rotary shaft cylinder protrusion 312 is not overlapped with the lock body groove 111, and the movable degree of freedom of the rotary shaft cylinder 310 along the axial direction of the first lock hole 110 is locked. Thus, in the case where the password component 300 is in a password error state, the padlock cannot perform password modification operations.

The first locking aperture 110 has a first end located at the first surface S1 and a second end remote from the first surface S1, as shown in fig. 1, and in some embodiments, the combination assembly 300 further includes a first plug 330, a second plug 340, and a shackle spring 350. The first plug 330 is disposed at a first end of the first lock hole 110, the first plug 330 has a receiving cavity 333, and a side of the first plug 330 facing the first lock hole 110 is provided with a first plug groove 331 communicating with the receiving cavity 333.

As shown in fig. 1 to 6, the second plug 340 is disposed at the second end of the first locking hole 110. The latch hook elastic member 350 is abutted between the second plug 340 and the first lock rod 210, when the code assembly 300 is in the correct code state and the lock cylinder 500 is in the lock cylinder unlocking state, that is, when the code assembly 300 is in the correct code state and the lock rod 400 is in the retracted state, the latch hook elastic member 350 pushes the latch hook 200 to a direction away from the second plug 340, and the latch hook protrusion 211 enters the accommodating cavity 333 through the rotating shaft barrel groove 311 and the first plug groove 331, so that the padlock is unlocked. The latch hook elastic member 350 is, for example, a spring.

The padlock of the above embodiment is provided with the shackle elastic member 350, and when the password assembly 300 is in the password correct state and the locking lever 400 is in the retracted state, the shackle elastic member 350 pushes the shackle 200 away from the second plug 340, so that the second shackle 200 automatically pops up relative to the second lock hole 120, thereby improving the convenience of padlock use.

As shown in fig. 1, in some embodiments, the password assembly 300 further includes a spindle barrel elastic member 360, where the spindle barrel elastic member 360 abuts between the second plug 340 and the spindle barrel 310, and the spindle barrel elastic member 360 pushes the spindle barrel 310 away from the second plug 340, so that the spindle barrel 310 enters the designated inner circumferential groove 321 in a default state of the spindle barrel 312. The spindle barrel elastic member 360 is, for example, a spring.

As shown in fig. 6, 11 and 12, when the padlock is in an unlocked state, the lock hook 200 can rotate around the first lock rod 210, and when the lock hook 200 rotates to a state that the lock hook protrusion 211 overlaps the second plug groove 332, the lock hook protrusion 211 does not overlap the rotating shaft barrel groove 311, the external force presses the lock hook 200 to enable the lock hook protrusion 211 to push the rotating shaft barrel 310 to move towards the direction close to the second plug 340 after passing through the second plug groove 332, so that the rotating shaft barrel protrusion 312 leaves the inner peripheral groove 321, the rotating shaft barrel 310 can be reassigned by the rotation of the code disc 320, and after the external force is removed, the rotating shaft barrel elastic piece 360 pushes the rotating shaft barrel 310 towards the direction away from the second plug 340, so that the rotating shaft barrel protrusion 312 enters the reassigned inner peripheral groove 321 to modify the code of the code assembly 300.

Fig. 13 is a schematic cross-sectional view of a transverse cross-section of an embodiment of a padlock of the utility model, as shown in fig. 1, 9 and 13, wherein a plurality of peripheral grooves 322 are formed on the periphery of the code wheel 320, and the number of peripheral grooves 322 is equal to the number of code labels 323. The first locking hole 110 has a limiting hole 112 on its inner side wall. The password assembly 300 further comprises a limiting ball 370 and a limiting elastic piece 380, wherein the limiting ball 370 is connected into the limiting duct 112 through the limiting elastic piece 380, the shape of the peripheral groove 322 is matched with the partial surface of the limiting ball 370, and the limiting elastic piece 380 pushes the limiting ball 370 to be abutted against the peripheral groove 322.

In this embodiment, the number of the peripheral grooves 322 is equal to the number of the code marks 323, and the peripheral grooves 322 and the code marks 323 are alternately arranged along the periphery of the code wheel 320. The stopper ball 370 is, for example, a steel ball, and the stopper elastic member 380 is, for example, a spring. Through setting up spacing ball 370 and spacing elastic component 380, can guarantee that code wheel 320 can not rotate at will under some interference external force, and make code wheel 320 can stop in the position that code mark 323 corresponds with the position of predetermineeing after the code wheel 320 is rotated at every turn.
