The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
A kind of door lock transmission mechanism comprises: handle assembly (1), first restoring board (2), second restoring board (3), first extension spring (4), second extension spring (5), annular are turn-taked (6), clutch (7), first connecting rod (8), second connecting rod (9); Wherein: handle assembly (1), first restoring board (2), second restoring board (3) concentric fits can be around same central axis rotation; The 3rd boss (13) is arranged on the handle assembly (1), first rib (21) and second rib (31) are arranged on first restoring board (2) and second restoring board (3), the 3rd boss (13) can be stirred first rib (21) and second rib (31); First boss (11) and second boss (12) are arranged on the handle assembly (1), and first boss (11) is connected with first connecting rod (8), and second boss (12) is connected with second connecting rod (9), and the other end of first connecting rod (8) is assemblied in annular and turn-takes on the 4th boss (61) of (6); Handle assembly (1) is appeared on the stage or is pressed down when rotating receiving external force; Through being connected of first boss (11) and first connecting rod (8); Second boss (12) is connected with second connecting rod (9); Can drive first connecting rod (8) and second connecting rod (9) moves up and down, turn-take on the 4th boss (61) of (6) because the other end of first connecting rod (8) is assemblied in annular, the other end of second connecting rod (9) is assemblied in annular and turn-takes on the 5th boss (62) of (6); When first connecting rod (8) and second connecting rod (9) when moving up and down, drive annular turn-take (6) rotate; Annular is turn-taked (6) and clutch (7) concentric fits; Can be around same central axis rotation; Annular is turn-taked has the 3rd rib (63) and the 4th rib (64) on (6); The 5th rib (71) and the 6th rib (72) are arranged on the clutch (7); Turn-take (6) when doing clockwise or rotating counterclockwise with moving up and down of first connecting rod (8) and second connecting rod (9) when annular, the 3rd rib (63) is stirred the 5th rib (71) or the 4th rib (64) is stirred the 6th rib (72), and clutch (7) rotates with the turn-take rotation of (6) of annular.
Press down under the external force effect when clockwise rotating when handle assembly (1) receives like Fig. 4; The 3rd boss (13) is stirred first rib (21) clockwise rotates first restoring board (2) together; Second extension spring (5) receives pulling force to produce tension type change; Simultaneously first connecting rod (8) moves downward, and second connecting rod (9) moves upward, and turn-takes on the 4th boss (61) of (6) because first connecting rod (8) other end is assemblied in annular; The other end of second connecting rod (9) is assemblied in annular and turn-takes on the 5th boss (62) of (6), and (6) are clockwise rotated by the drive of first connecting rod (8) and second connecting rod (9) so annular is turn-taked; When annular is turn-taked (6) when clockwise rotating, its 3rd rib (63) is stirred the 5th rib (71), clockwise rotates thereby drive clutch (7); After the external force on the handle assembly (1) disappears; Under the restoring force effect of second extension spring (5); First restoring board (2) resets together, and while first rib (21) is stirred the 3rd boss (13) counterclockwise resets handle assembly (1) counterclockwise, and first connecting rod (8) moves upward and returns back to original position; Second connecting rod (9) moves downward and returns back to original position; The return motion of first connecting rod (8) and second connecting rod (9) drive annular turn-take (6) do counterclockwise reseting movement together, the 4th rib this moment (64) is stirred the 6th rib (72), thereby clutch (7) is resetted counterclockwise.
Like Fig. 6; When receiving, handle assembly (1) appears on the stage under the external force effect when rotating counterclockwise; The 3rd boss (13) is stirred second rib (31) rotates counterclockwise second restoring board (3) together, and first extension spring (4) receives pulling force to produce tension type change, and first connecting rod (8) moves upward simultaneously; Second connecting rod (9) moves downward; Because first connecting rod (8) other end is assemblied in annular and turn-takes on the 4th boss (61) of (6), the other end of second connecting rod (9) is assemblied in annular and turn-takes on the 5th boss (62) of (6), and (6) are rotated counterclockwise by the drive of first connecting rod (8) and second connecting rod (9) so annular is turn-taked; When annular is turn-taked (6) when rotating counterclockwise, its 4th rib (64) is stirred the 6th rib (72), rotates counterclockwise thereby drive clutch (7); After the external force on the handle assembly (1) disappears; Under the restoring force effect of first extension spring (4); Second restoring board (3) resets together, and while second rib (31) is stirred the 3rd boss (13) counterclockwise resets handle assembly (1) clockwise, and first connecting rod (8) moves downward and returns back to original position; Second connecting rod (9) moves upward and returns back to original position; The return motion of first connecting rod (8) and second connecting rod (9) drive annular turn-take (6) do clockwise reseting movement together, the 3rd rib this moment (63) is stirred the 5th rib (71), thereby clutch (7) is resetted clockwise.
To sum up, the design utilizes a series of mechanics transmission principles, realizes making the motion of clutch main story when handle presses down, and handle is appeared on the stage and made the clutch return motion, thereby realizes other transmission agency.
