The operation of the silent door stopper 1 will be described below.
As shown in fig. 15, when the door leaf 2 slowly approaches the seat head 3 along the direction F, the second magnetic piece 22 first approaches the second swing end 91S of the swing head 9. Since the polarity of the second magnetic force piece 22 is the same as that of the second pendulum end 91S, the second pendulum end 91S receives the repulsive force of the second magnetic force piece 22, the pendulum head 9 slowly rotates counterclockwise along the direction R1, and the first pendulum end 91N of the pendulum head 9 starts to approach the first magnetic force piece 21. Since the polarity of the first magnetic piece 21 is opposite to the first swing end 91N, the first swing end 91N is attracted to the first magnetic piece 21, as shown in fig. 16, and at this time, the attraction and fixation of the door 2 is completed.
When the door leaf 2 is rapidly close to the seat head 3 along the direction F, the second magnetic sheet 22 enables the swing head 9 to rapidly rotate counterclockwise along the direction R1 through the magnetic repulsion force, the three synchronous pawls M swing outward under the action of centrifugal force, the rotating bracket 11 locks the linkage ring 7, the linkage ring 7 synchronously drives the linkage disc 6, and the linkage disc 6 synchronously drives the damper 5. Then, the damper 5 is started to rapidly reduce the rotation speed of the rotating bracket 11, and the first swing end 91N is slowly attracted to the first magnetic piece 21, thereby completing the attraction and fixation of the door 2.
When the user separates the door leaf 2 from the seat head 3, the swinging head 9 is reset under the action of self gravity, and the next adsorption operation is prepared.
The operation of the synchronizing pawl M will be further explained below.
As shown in fig. 17 and 18, when the door leaf 2 approaches the seat head 3 slowly, the rotating speed of the rotating bracket 11 is low, the centrifugal force applied to the synchronous pawl M is not enough to make the pawl arc 13 swing outwards, and at this time, the rotating bracket 11 can rotate freely.
As shown in fig. 19 and 20, when the door leaf 2 is rapidly close to the seat head 3, the rotating speed of the rotating bracket 11 is high, the centrifugal force applied to the synchronization pawl M causes the pawl arc 13 to swing outward, the ratchet head 132 of the pawl arc 13 abuts against the interlocking protrusion 71 of the interlocking ring 7, and then the synchronization pawl M locks the interlocking ring 7. At this time, the rotation of the rotating bracket 11 is rapidly reduced by the interference of the damper 5. After the first pendulum end 91N is slowly adsorbed to the first magnetic sheet 21, the synchronous pawl M is reset under the action of the reset spring 16, and the synchronous pawl M unlocks the linkage ring 7.
Because the impact of door leaf can effectively be alleviated to this silence door-inhale, the silence performance is good, is fit for modern house and uses.
