Specific embodiment
It is described in further details referring to locking mechanism embodiment of the attached drawing 1 to Fig. 5 to a kind of error preventing lock of the utility model.
A kind of locking mechanism of error preventing lock including lock tongue 1, lock body 2 and is arranged in lock body 2 and locks 3 and of actuator
The lower end of lock tongue side's mandrel 4, the lock tongue 1 is rotated on setting lock body 2 by pin shaft, and end setting thereon is opened up in lock body 2
Lockhole 21 on, wherein in 4 rotation process of lock tongue side's mandrel, the upper end that will drive lock tongue 1 is rotated around pin shaft, the lock
The upper end of tongue 1 is stretched out lockhole 21 or is retracted in lockhole 21；
The actuator 3 of locking lock body 2 can be moved forward and backward relatively, and the actuator 3 of locking is provided with instead towards 1 direction of lock tongue
Lock section 31；The conflict piece 5 being rotatably arranged on lock body 2, described one end for contradicting piece 5 are equipped between the portion of locking 31 and lock tongue 1
Portion is embedded on lock tongue 1, and the other end is oppositely arranged with the portion of locking 31, when the upper end of lock tongue 1 is rotated around pin shaft, the lock
The upper end of tongue 1, which will drive, contradicts the rotation of piece 5, realizes that contradicting piece 5 contradicts or separate with the portion of locking 31；
Under the condition of opening, lock tongue 1 is placed in lockhole 21, and the conflict piece 5 is inconsistent with the portion of locking 31 at this time, limitation
The forward movement of actuator 3 is locked, prevent locking actuator 3 from driving lock tongue 1 to stretch out outside lockhole 21, people is effectively avoided to open
It is not intended to lock tongue 1 to lock out in the state of door or child locks out when playing lock tongue 1, to avoid under wind action
Or the promotion of child causes the damage of lock body 2, under shutdown state, lock tongue 1 is in button box at this time after lock tongue 1 is hit with doorframe
Under upper magneticaction, the upper end of lock tongue 1 is rotated around pin shaft to be stretched out outside lockhole 21, and the lower end of lock tongue 1 will drive conflict at this time
The rotation of piece 5 is separated with the portion of locking 31, locks the limitation of actuator 3 to release, locking actuator 3 at this time can move forward, and drive
It is described lock portion 31 and be resisted against on the upper end of lock tongue 1 locked, will not influence normal back locking function.
Another embodiment of the utility model, the main distinction are: further including linkage piece 6 and tension spring 7；
The linkage piece 6 is rotatably arranged on lock body 2, and it is placed in and locks actuator 3 and contradict between piece 5, and
The linkage piece 6 includes the first linkage portion 61 and the second linkage portion 62；One end of the tension spring 7 is connected with linkage piece 6, another
End is connected with actuator 3 is locked, so that linkage piece 6 is resisted against in the portion of locking 31；
Wherein arc groove 22 is arranged in the lock body 2, and first linkage portion 61 can be moved arcuately slot 22, be locked when described
Portion 31 pushes linkage piece 6 to rotate towards the upper end direction of lock tongue 1, so that arcuately slot is mobile for the first linkage portion 61 of linkage piece 6
It is resisted against on the upper end of lock tongue 1 and is locked, the second linkage portion 62 and lock tongue side's mandrel 4 are inconsistent, so that linkage piece 6 rotates
It is more reliable and more stable, play guiding role.
Under the condition of opening, lock tongue 1 is placed in lockhole 21, and the conflict piece 5 is inconsistent with linkage piece 6 at this time, to limit
System locks the forward movement of actuator 3, prevent locking actuator 3 from driving lock tongue 1 to stretch out outside lockhole 21, effectively people is avoided to exist
It is not intended to lock tongue 1 to lock out in the state of enabling or child locks out when playing lock tongue 1, to avoid in wind action
After lower or child promotion, lock tongue 1 and doorframe are hit, the damage of lock body 2 is caused, under shutdown state, lock tongue 1 is being detained at this time
On box under magneticaction, the upper end of lock tongue 1 is rotated around pin shaft to be stretched out outside lockhole 21, when the upper end of lock tongue 1 is rotated around pin shaft
When stretching lock body 2 is outer, the lower end of lock tongue 1 will drive the conflict rotation of piece 5 and separate with linkage piece 6, lock actuator 3 to release
The forward movement of actuator 3 is locked in limitation at this time, and the portion 31 of locking pushes linkage piece 6 to rotate towards the upper end direction of lock tongue 1,
It is locked so that the first linkage portion 61 of linkage piece 6 is resisted against on the upper end of lock tongue 1, the second linkage portion 62 and lock tongue Fang Xin
Axis 4 is inconsistent, and limitation lock tongue side's mandrel 4 rotates, and improves door lock safety.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
