Under the action of the limiting component 41, the push-pull rod 42 drives the limiting deflector rod 43 to downwards press the limiting deflector rod 43, so that the roller 431 enters an included angle formed by the contact of the clamping bottom surface 1212 of the bidirectional inclined tongue portion 1 and the main body of the linkage portion 12, and the bidirectional inclined tongue portion 1 is limited.
At this time, the mute driver 61 has no other external force, the driving elastic body 62 keeps the mute driver 61 pressing the connecting sidewall 6313 of the mute limiter 63 with the stop lever positioning post 53 as an axis under the tension, and the mute limiter 63 is pressed and the clip vertex 6322 does not contact the latch 124 because the elastic force of the driving elastic body 62 is larger than the elastic force of the stop elastic body 64.
Fig. 12 shows the main lock tongue portion 7 of the lock body having been retracted into the housing portion by the motor 8, and at this time, the two-way oblique tongue portion 1 still extends out of the side edge 51, and the sub-lock portion 2 is still shielded by the door frame, does not extend out of the side edge 51, and is retracted into the housing portion.
Under the action of the limiting component 41, the push-pull rod 42 drives the limiting deflector rod 43 to downwards press the limiting deflector rod 43, so that the roller 431 enters an included angle formed by the contact of the clamping bottom surface 1212 of the bidirectional inclined tongue portion 1 and the main body of the linkage portion 12, and the bidirectional inclined tongue portion 1 is limited.
At this time, the mute driving part 61 still has no other external force, the driving elastic body 62 keeps the mute driving part 61 pressing the connecting side wall 6313 of the mute limiting part 63 with the limit lever positioning post 53 as an axis under the tension, and the mute limiting part 63 is pressed and the clip vertex 6322 is not contacted with the latch part 124 because the elastic force of the driving elastic body 62 is larger than the elastic force of the limit elastic body 64.
Fig. 13 to 14 show the state when the main lock tongue portion 7 is unlocked and the handle portion 3 is pressed, at this time, the handle portion 3 is rotated by the handle, the handle pushing member 31 contacts and presses the driving portion groove 6143, so that the mute driving portion 61 rotates clockwise with the limit lever positioning post 53 as an axis, and further presses the driving elastic body 62, at this time, the driving push rod top 6131 of the driving push rod 613 stops pressing the connection side wall 6313, the mute limiting portion 63 rotates counterclockwise with the mute positioning post 55 as a rotation axis under the tension of the limit elastic body 64, the clip vertex 6322 of the mute limiting portion 63 is lifted up, and the clip vertex 6322 enters the latch side wall 1242 of the latch portion 124.
When the limit deflector 43 rotates clockwise with the limit deflector positioning post 53 as an axis under the drive of the handle 3, the limit deflector 43 drives the roller 431 to leave the clamping bottom surface 331, and the limit of the bidirectional inclined tongue 1 is released.
Fig. 15 to 16 show the main latch portion 7 of the lock body in a state when the handle portion 7 is unlocked and pushed, at this time, the sub-lock portion 2 extends out of the side edge 51 of the housing portion without the blocking of the door frame, so that the limiting assembly 41 drives the push-pull rod 42 to lift the limiting deflector rod 43 axially by taking the limiting deflector rod positioning post 53, so that the limitation of the roller 431 on the bidirectional inclined tongue portion 1 is cancelled and can be kept continuously, the bidirectional inclined tongue portion 1 can be retracted into the housing portion, when the door is pushed, the bidirectional inclined tongue portion 1 can be retracted into the housing portion under the action of the edge of the door frame, and when the bidirectional inclined tongue portion 1 is retracted inwards to slide, the clamping peak 6322 is clamped into the clamping tooth 1241 of the clamping portion 124, so that the bidirectional inclined tongue portion 1 is limited, and the bidirectional inclined tongue portion 1 is fixed in the retracted housing portion and cannot extend out of the housing portion.
At this time, the door body is pushed open, so that the door can be opened, at this time, because the clamping peak 6322 limits the unidirectional locking tongue portion 1, when the door is opened to the edge of the door frame, the oblique tongue portion 11 does not contact the edge of the door frame, that is, the oblique tongue portion 11 does not generate the sound of striking the door frame, so as to realize the silencing effect.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
