Specifically, the button 3 is slidably connected with the lock cover 1 and the lock gate seat 5, a sliding groove is provided on the button 3, and a guide rail is provided on the lock cover 1 and the lock gate seat 5, and the sliding seat and the guide rail cooperate to guide the button 3.

[0042] Preferably, the button-opening password lock with overload protection further includes a second elastic member 7, and the two ends of the second elastic member 7 act on the lock gate seat 5 and the button 3 respectively. Specifically, a second receiving groove is provided on both the left and right sides of the lock gate seat 5, the second elastic member 7 is a compression spring, the second elastic member 7 is arranged in the second receiving groove, and the two ends of the second elastic member 7 are pressed against the lock gate seat 5 and the button 3 respectively, and the second elastic member 7 is used to drive the button 3 to move in a direction away from the lock gate seat 5, so that the button 3 automatically returns to its original position.

[0043] The button 3 and the lock gate seat 5, one of which is provided with a strip hole 31, the length direction of which is provided along the sliding direction of the button 3, and the other is provided with a connecting member 51 which penetrates the strip hole 31. In this embodiment, the strip hole 31 is provided on the button 3, and the connecting member 51 is a screw, which is threadedly connected to the lock gate seat 5. The connecting member 5 is used to limit the button 3 and allow the button 3 to have a certain amount of movement relative to the lock gate seat 5.

[0044] Preferably, the button-opening password lock with overload protection also includes a buckle cover (not shown in the figure), which is buckled on the lock cover 1, and the button 3 is partially exposed on the buckle cover. The buckle cover is used to cover the lock gate seat 5, the first elastic member 6, the second elastic member 7 and the password mechanism 4, etc.

[0045] The password mechanism 4 includes a password wheel assembly 41, a control panel 42 and a reset button 43.

[0049] Initially, the control panel 42 is located below the lock gate seat 5, which can stop the lock gate seat 5 to prevent unlocking.

[0050] Unlocking process: rotate the code wheel of the code wheel assembly 41 so that each code wheel is in the correct code state, and then make the third elastic member 8 drive the control board 42 to move away from the lock cover 1 so that the control board 42 no longer stops the lock gate seat 5.

[0051] Pressing the button 3 compresses the second elastic member 7 , and then drives the lock gate seat 5 to drive the lock gate 2 to move to unlock the door; the first elastic member 6 is compressed during the movement of the lock gate seat 5 .

[0052] After unlocking, under the elastic force of the first elastic member 6 and the second elastic member 7, the lock gate seat 5 will drive the lock gate 2 to return or lock, and the button 3 will also return. The button 3 can play the role of overload protection, that is, when the password is wrong, the button 3 is violently hit, and the button 3 compresses the second elastic member and can be pressed in, but the lock gate seat 5 is stopped by the control panel 42, and the password lock cannot be opened. In addition, the first elastic member 6 and the second elastic member 7 also have a buffering effect to ensure that the password lock is not damaged. The password wheel assembly 41 and the button 3 cooperate to unlock, which increases the safety performance of the password lock and also protects the password lock.

[0053] When the password is correct, pressing button 3 can open the password lock normally; when the password is wrong, there will be overload protection inside the lock head, button 3 can be pressed but cannot open the password lock normally, preventing destructive opening of the password lock.
