When the hard ball 200 moves inward, the hard ball 200 can continue to move inward due to the inclined surface 321 structure, so that the latch body 320 can continue to Move down; latch 300 bottom with first accommodation 810 is provided between the bottom surface of the

latch spring

30a, 30a of the latch spring for the latch 300 is reset.

Further, in the second accommodating cavity 820, a latching chamber 821 is disposed in the second accommodating cavity 820. The latching 400 is laterally movable in the latching chamber 821, and one end of the latching 400 is disposed between the end of the latching chamber 821 and the side wall of the latching chamber 821. There is a lock compression spring 40a, and the lock compression spring 40a is used to reset the lock 400.

Further, in the embodiment, the other end of the locking chamber 821 is provided with a driving chamber 822. The driving chamber 822 is used for mounting the unlocking portion 700 and the motor 600. The other end of the locking buckle 400 is engaged with the unlocking portion 700. The unlocking portion 700 is rotated, and the unlocking portion 700 is an eccentric wheel, an eccentric rod or a cam.

The motor 600 preferably employs a geared motor, and the unlocking portion 700 and the motor 600 are used to achieve lateral movement of the buckle 400; the unlocking portion 700 is driven by the motor 600 to achieve rotation, and the motor shaft is usually used for connection.

In combination with the above, the principle that the padlock is unlocked by the unlocking portion 700 and the motor 600 is: when the padlock is in the locked state, the latch cavity 410 is located on the side of the latch bottom block 330, and the bottom of the latch bottom block 330 cannot be moved downward at this time. As defined by the upper surface of the buckle 400, the latch bottom block 330 cannot be embedded in the latch cavity 410; when unlocking is required, the unlocking portion 700 is driven to rotate by the motor 600, and the lock 400 can be laterally moved to the other end to drive the lock. The latch cavity 410 is displaced. When the latch cavity 410 moves to the lower portion of the latch bottom block 330, the unlocking portion 700 stops rotating; the bottom end of the long lock bar 110 in the lock beam 100 is subjected to the rebound force of the lock beam compression spring 10a, and the lock beam 100 When the whole movement is upward, the long lock bar 110 and the inner end groove 120 of the short lock bar 150 move upward, and the hard ball 200 is forced to move inward along the lateral receiving cavity 812. The hard ball 200 cooperates with the inclined surface 321 , and the inclined surface 321 is forced to cause The latch body 320 moves downward integrally, and the cooperation of the latch top block 310 with the first longitudinal receiving cavity 811 improves the stability of the movement of the latch 300 while the bottom latch block 330 is embedded in the latch cavity 410. The latch compression spring 30a is now at In the state of force, when the hard ball 200 and the lock beam 100 are completely disengaged, the short lock lever 150 in the lock beam 100 is disengaged from the short blind hole 840, and the padlock is unlocked, and the latch 300 and the lock 400 are respectively passed through the latch compression spring 30a and The lock compression spring 40a completes the reset.

The above structure is driven by the motor 600 to unlock the motor 600. The motor 600 can also be connected to the controller 900. The controller 900 includes a verification module and a control module. The controller 900 can be composed of electronic components commonly used in the prior art. The motor 600 and the verification module are both The control module is electrically connected, and the control module is configured to supply power to the motor when the verification module passes the verification. The verification module can be one of a Bluetooth verification module, a password input module, a voice verification module, a face recognition module, and a fingerprint verification module. After the verification module passes the verification, the control module supplies power to the motor 600, and the unlocking portion 700 presses the lock 400 to move, and combines the above principles to achieve unlocking.

Further, in the embodiment, the lower portion of the lock chamber 821 is provided with a mechanical lock cylinder chamber 823 for mounting the mechanical lock cylinder 500, and the mechanical lock cylinder 500 is used for pushing the lock 400 to move laterally.

According to the above structure, the mechanical lock cylinder 500 can replace the electronic unlocking structure of the motor 600 and the unlocking block 700. The mechanical lock cylinder 500 can be used to realize the lateral movement of the buckle 400, thereby completing the unlocking.

In the above structure, the mechanical lock cylinder 500 is a component in the prior art, and the lower portion of the buckle 400 is integrally provided with a moving block 420. The moving block 420 is engaged with the unlocking end of the mechanical lock cylinder 500, and the mechanical lock cylinder 500 uses the unlocking end to move the block. The 420 achieves a push push to complete the movement of the position of the buckle 400.

In this embodiment, the mechanical unlocking principle is: when the padlock is in the locked state, the latch cavity 410 is located on the side of the latch bottom block 330, and at this time, the bottom of the latch bottom block 330 cannot move downward, and the upper surface of the latch 400 is It is defined that the latch bottom block 330 cannot be embedded in the latch cavity 410; when unlocking is required, the unlocking end of the mechanical lock cylinder 500 rotates, and the lock 400 can be pressed laterally to the other end to drive the latch cavity 410 to be displaced. By using the limit rotation in the mechanical lock cylinder 500, the latch cavity 410 just moves to the lower part of the latch bottom block 330; the bottom end of the long lock bar 110 in the lock beam 100 is subjected to the rebound force of the lock beam compression spring 10a, and the lock beam 100 as a whole The upward movement of the long lock bar 110 and the inner end of the short lock bar 150 moves upward, and the hard ball 200 is forced to move inward along the lateral receiving cavity 812. The hard ball 200 cooperates with the inclined surface 321 , and the inclined surface 321 is forced to cause the latch The body 320 moves downward as a whole, and the cooperation of the latch top block 310 with the first longitudinal receiving cavity 811 improves the stability of the movement of the latch 300 while the bottom latch block 330 is embedded in the latch cavity 410. The compression spring 30a is now under stress, when the hard ball 200 After releasing the locking beams 100 to complete engagement, the locking beams 100 within a short locking bar 150 is disengaged from the blind bore 840 in short, to achieve the padlock is unlocked, the latch 300 and the striker 400 are reset by the latch 40a to complete the compression spring 30a and the striker spring.

Further, in the present embodiment, the lock body 800 has a circular, quadrangular, hexagonal or octagonal shape, preferably a circular structure and an octagonal structure. In particular, the lock body 600 of the octagonal structure is generally called an octagonal structure. lock.
