The first elastic portion 61 and the second elastic portion 14 are both compression springs.

Referring to FIG. 9 , the lock body 2 further includes a partition plate 7 , and the partition plate 7 is used to install the rotating column 5 and determine the axial position of the rotating column 5 . The driven tooth fixed shaft 54 passes through the partition plate 7 , the outer peripheral surface of the driven tooth fixed shaft 54 also has a rotation limit portion 541 , and the partition plate 7 is provided with a limit corresponding to the rotation limit portion 541 . As for the matching portion 71 , when the rotation limiting portion 541 abuts against the limiting matching portion 71 , the steel ball 4 engages with the matching recess 15 . When the rotation limiting portion 541 abuts against the limiting engaging portion 71 , the rotating column 5 is in the locking position, and when the rotating limiting portion 541 is away from the limiting engaging portion 71 , the rotating column 5 is in the unlocking position. The partition plate 7 is also provided with a positioning groove 72 and a through hole 73 . The positioning slot 72 is used to accommodate part of the locking beam 1 . The through hole 73 allows the circular connection end 533 of the rotating column main body 53 to pass through.

The electronic lock cylinder 3 is used to rotate the driving teeth 311 to rotate the rotating column 5 from the locking position where the 531 is facing the steel ball 4 to the unlocking position where the plane portion 532 is facing the steel ball 4 , In order to allow the steel ball 4 to be completely separated from the matching recess 15; the electronic lock cylinder 3 is also used to rotate the driving tooth 311 to rotate the rotating column 5 from the unlocking position to the locking position, so that the steel The ball 4 is engaged with the matching recess 15 to realize the locking of the lock body 2 and the lock beam 1 .

The electronic lock cylinder 3 is used to drive the lock tongue 6 to cooperate with the lock beam 1 to lock or unlock. The electronic lock cylinder 3 is driven by a motor, and the electronic lock cylinder 3 is fixed in the lock body 2 .

The lock body 2 is provided with a through hole 212 corresponding to the pressing portion 63 , the first elastic portion 61 is located between the lock body 2 and the pressing portion 63 , and the pressing portion 63 is provided with the The first elastic portion 61 corresponds to the limiting hole 631 , and the first elastic portion 61 is also used to keep the pressing portion 63 passing through the through hole 212 and in contact with the inner wall of the lock body 2 .

The padlock also includes a verification module and a control module. The electronic lock cylinder 3 and the verification module are both electrically connected to the control module. The electronic lock cylinder 3 is powered, and the verification module is one of a Bluetooth verification module, a password input module, a voice verification module, a face recognition module, and a fingerprint verification module 23 .

The long lock lever 11 is also provided with a fixed concave ring 111 for preventing the lock beam 1 from being completely separated from the lock body 2 when the lock beam 1 is unlocked. When the rotating column 5 is in the locked position, the steel ball 4 is partially accommodated in the fixed concave ring 111, and The steel ball 4 restricts the upward movement of the locking beam 1 . The recessed depth of the mating recess 15 is greater than that of the fixing recessed ring 111 . There is an excessive depression 112 between the fixed concave ring 111 and the matching depression 15. The excessive depression 112 is used for the lock beam 1 to smoothly move from the matching depression 15 to the fixed concave ring 111 during the unlocking process or the locking beam 1 during the locking process. It can smoothly move from the fixed concave ring 111 to the matching recess 15 .

During use, the user inputs the verification information in a manner corresponding to the verification module. After the verification module passes the verification, the control module controls the power supply to supply power to the electronic lock cylinder 3, and the driving teeth are connected to the end of the electronic lock cylinder 3 to drive the driven teeth 5a. The rotation makes the rotating column 5 rotate from the locking position to the unlocking position, at this time, the limiting column 542 is away from the contact surface 622, and then the pressing part 63 is pressed, and the push block 62 is separated from the locking notch 16 by moving the lock tongue 6,

Under the action of the second elastic portion 14, the steel ball 4 is squeezed by the matching recess 15 and disengages from the matching recess 15, and the locking beam 1 moves upward to the open position. During the upward movement of the locking beam 1, the concave surface 621 of the push block 62 is located outside the locking notch 16, allowing the locking beam 1 to move up and down.

When the user needs to lock the padlock again, the user presses the arc-shaped connecting rod 12 to make the short lock rod 13 enter the hole of the lock beam 1. When the position of the matching recess 15 corresponds to the steel ball 4, under the action of the first elastic part 61 , part of the push block 62 is returned to the matching recess 15, so that the push block 62 restricts the movement of the lock beam 1, and then the verification information is input again through the method corresponding to the verification module. The unlocked position rotates to the locked position. At this time, the 531 of the rotating column 5 faces the steel ball 4, and the 531 squeezes the steel ball 4 and restricts it in the matching recess 15, so as to realize the locking of the lock body 2 and the lock beam 1.

In the present invention, the movement of the lock tongue 6 is restricted by the rotating column 5 to prevent the lock beam 1 from being unlocked by mistakenly touching the pressing portion 63, so that the padlock has a better locking effect.

In the present invention, the rotation column 5 is used to initially unlock the lock beam 1, and then the lock beam 1 is completely unlocked by pressing the pressing portion 63, so that the padlock has a more complicated unlocking method and improves the use safety of the padlock.

In the padlock of the utility model, the locking or unlocking of the padlock is realized by controlling the protruding part or the flat part of the rotating column to face the steel ball, and the structure of the padlock is simple and compact.

In the present invention, the padlock has a better pull-out force through the matching recess 15 corresponding to the steel ball 4 and the locking notch 16 corresponding to the push block 62 .

In the present invention, by manually pressing the pressing portion 63, the lock tongue 6 is released from the restriction on the lock beam 1 and the unlocking is completed, thereby reducing the power requirement for the battery 3a and the torque requirement for the motor, so that the battery 3a has a longer The standby time can reduce the volume of the motor, and indirectly make the padlock more compact and lightweight, so the padlock has the beneficial effects of simple structure, low cost, long standby time and safer use.

The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. Professional and technical personnel, within the scope of the technical solution of the present invention, can make some changes or modifications to equivalent examples of equivalent changes by using the technical content disclosed above, provided that the content of the technical solution of the present invention is not departed from, Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solutions of the present invention.
