While controlling the unlocking or locking of the lock beam 20, it simultaneously controls the unlocking or locking of the co-locking slider 60. Therefore, the lock beam 20 and the co-locking slider 60 are in a synchronous sliding state. Then, through the corresponding conduction between the co-locking sliding hole / groove 61 and the locking sliding hole / groove 11, the additional auxiliary lock (not shown in the figure) is passed through the co-locking sliding hole / groove 61 and the locking sliding hole / groove 11, thereby locking the co-locking slider 60, achieving the purpose of co-locking while ensuring the reliability of locking.

[0029] In this embodiment, the locking beam 20 includes a fixed beam 21 and a movable beam 22. The fixed beam 21 and the movable beam 22 are connected in an n-shape by a beam bridge 23.

[0040] In the above structure, the sliding degree of freedom of the common locking slider 60 is locked or unlocked by the cam disk 42.

[0041] In this embodiment, the co-locking part 62 is provided with a co-locking groove 621; when the cam disk 42 is located in the co-locking groove 621, it locks the co-locking slider 60; when the unlocking notch 421 is rotated to correspond to the co-locking groove 621, the co-locking slider 60 is in an unlocked state.

[0042] In the above structure, the cam disk 42 can be replaced by a non-rotating structure along the circumferential direction of the drive rod 40.

[0043] In this embodiment, the co-locking sliding hole / groove 61 and the locking sliding hole / groove 11 are configured as one or more.

[0044] The above structure allows for the simultaneous locking of multiple auxiliary locks (not shown in the figure).

[0045] In this embodiment, the co-locking slider 60 is provided with a slot 63, and the end of the fixed beam 21 is provided with a rotary joint 212 adapted to the slot 63. The locking beam 20 rotates relative to the co-locking slider 60 with the axis of the fixed beam 21 as the center when it is in the unlocked and popped-out state.

[0046] In the above structure, the ease of loading and unloading the co-locking padlock is improved by rotating the locking beam 20 after it is unlocked and popped out.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
