Abstract

Claims (30)

1 . A reset auxiliary structure for cipher wheel locks, comprising:

a knob ( 10 );

a cipher wheel assembly ( 20 ) rotatable relative to the knob ( 10 );

a reset cam ( 30 ); and

an auxiliary guide block ( 40 );

wherein the knob ( 10 ) is centrally provided with a receiving chamber for accommodating the cipher wheel assembly ( 20 );

wherein the cipher wheel assembly ( 20 ) includes a positioning piece ( 21 ) and a shifting lever ( 22 ) disposed on the positioning piece ( 21 );

wherein the reset cam ( 30 ) is synchronously rotatable with the knob ( 10 ); the reset cam ( 30 ) includes a reset surface ( 31 ) and guide surfaces ( 32 ) connected to the reset surface ( 31 ); the guide surfaces ( 32 ) are disposed on two sides of the reset surface ( 31 ), and the reset surface ( 31 ) is positioned at a highest point of the reset cam ( 30 );

wherein the auxiliary guide block ( 40 ) is movable relative to the reset cam ( 30 ); and a support surface of the auxiliary guide block ( 40 ) is positioned beside the reset surface ( 31 );

wherein the shifting lever ( 22 ) is operatively connected with the reset cam ( 30 );

wherein after being tilted by the guide surfaces ( 32 ), the shifting lever ( 22 ) is engaged with both the reset surface ( 31 ) and the support surface of the auxiliary guide block ( 40 ); and

wherein a side wall of the auxiliary guide block ( 40 ) is in abutting engagement with a side wall of the shifting lever ( 22 ), and when the shifting lever ( 22 ) tilts on the guide surfaces ( 32 ), the auxiliary guide block ( 40 ) is displaced relative to the reset cam ( 30 ).

2 . The reset auxiliary structure for cipher wheel locks according to claim 1 , further comprising a turntable ( 50 );

wherein the turntable ( 50 ) is rotatable relative to the reset cam ( 30 ); and

wherein the auxiliary guide block ( 40 ) is operatively connected to the turntable ( 50 ).

3 . The reset auxiliary structure for cipher wheel locks according to claim 2 , wherein the knob ( 10 ) comprises a base plate ( 11 ); and

wherein the turntable ( 50 ) is rotatably connected to the base plate ( 11 ); the reset cam ( 30 ) is arranged on the base plate ( 11 ).

4 . The reset auxiliary structure for cipher wheel locks according to claim 3 , wherein the base plate ( 11 ) is provided with a connection slot ( 12 ); the turntable is provided with a limiting protrusion; and

wherein the limiting protrusion is positioned within the connection slot ( 12 ).

5 . The reset auxiliary structure for cipher wheel locks according to claim 3 , wherein a peripheral side of the turntable ( 50 ) is provided with a limiting groove ( 52 ); the base plate ( 11 ) is provided with a limiting block ( 13 ); and

wherein the cooperation between the limiting block ( 13 ) and the limiting groove ( 52 ) restricts the rotational angle of the turntable ( 50 ).

6 . The reset auxiliary structure for cipher wheel locks according to claim 4 , wherein a pin shaft ( 14 ) is provided on the base plate ( 11 ); the turntable ( 50 ) is fitted over the pin shaft ( 14 ); the middle of the pin shaft ( 14 ) is provided with a connection hole ( 15 ); a fixing bolt ( 16 ) is fitted within the connection hole ( 15 ); and

wherein the turntable ( 50 ) is connected to the knob ( 10 ) through the cooperation of the fixing bolt ( 16 ) and the connection hole ( 15 ).

7 . The reset auxiliary structure for cipher wheel locks according to claim 6 , wherein the turntable ( 50 ) is positioned at a center of the base plate ( 11 ); the reset cam ( 30 ) is located on an outer periphery of the turntable ( 50 ); the auxiliary guide block ( 40 ) is located on the inner periphery of the reset cam ( 30 ); and

wherein the reset surface ( 31 ) of the reset cam ( 30 ) and the support surface of the auxiliary guide block ( 40 ) are simultaneously engaged with the shifting lever ( 22 ).

8 . The reset auxiliary structure for cipher wheel locks according to claim 1 , wherein the positioning piece ( 21 ) includes a rotating shaft ( 23 ); and

wherein the positioning piece ( 21 ) is rotatable relative to the cipher wheel assembly ( 20 ) when tilted by the cooperation between the shifting lever ( 22 ) and the reset cam ( 30 ).

9 . The reset auxiliary structure for cipher wheel locks according to claim 8 , wherein the rotating shaft ( 23 ) is located on an outer periphery of the reset cam ( 30 );

a lower end of the guide surface ( 32 ) is connected to a base plate ( 11 ); and

wherein the guide surface ( 32 ) is a curved surface.
