Abstract

The utility model discloses an electric lock mechanical device, which comprises a lock catch box and a lock box, wherein a direct-current decelerating motor, a gear, a rack, an ejecting body, a triggering plate, a lever and a limiting device are installed in the lock catch box; and a spring bolt, a bracket, a pothook, a hanging column, and a spring bolt extension self-locking mechanism are installed in the lock box. When the direct-current decelerating motor in the lock catch box drives the ejecting body to push the spring bolt into the lock box, the aim of unlocking in a power-driven way is realized; and when a door needs to be closed, a contact on the spring bolt hits against the triggering plate so as to trigger the pothook to be separated from the hanging column, and the bracket pushes the spring bolt into a lock catch hole under the elasticity of a spring arranged in a spring bolt pushing rod, so that the aim of locking is realized. The electric lock mechanical device can effectively solve the problems that a line of an electric lock is easy to be broken and an electronic element is easy to be damaged due to vibration.

The specific embodiment

Below Fig. 1, Fig. 2 and Fig. 3 are carried out the component explanation:

By shown in Figure 1, DC speed-reducing 1 is housed in the keeper, gear 2 is installed on the axle of DC speed-reducing 1, gear 2 and tooth bar 3 engagements that are installed on the support 10, tooth bar 3 is fixedlyed connected with acrosome 4, and acrosome 4 is connected with trigger board 5 by lever 7.The rotation of DC speed-reducing 1 is with the rotation of driven gear 2, the gear 2 that rotates drives the tooth bar 3 that is engaged with and does rectilinear motion, acrosome 4 is along with tooth bar 3 is done consistent with it rectilinear motion, and by

stopping means

6a, 6b limits the moving range of tooth bar 3 and acrosome 4; Simultaneously, acrosome 4 is stirred trigger board 5 by lever 7 and is done the motion of direction in contrast.

By shown in Figure 2, contact 11a, 11b correspondence are installed in dead bolt 12a, the 12b, dead bolt 12a, 12b are fixed on the carriage 13, when dead bolt 12a, 12b are moved to rearmost end position (away from the keeper position) or are shifted onto the rearmost end position by acrosome 4 by pull bar 17 after, hook 21 on the carriage 13 is under the elastic force effect of spring 22, to collude on hanging column 19, dead bolt 12a, 12b can not eject; When contact 11a hits trigger board 5 on the keeper, contact 11a is extruded back in the lock box, to promote hook 21 be that the center clockwise rotates with rotary screw 23 by triggering push rod 24, hook 21 breaks away from hanging column 19, promotes carriage 13 under the elastic force effect of dead bolt push rod 25 built-in springs, and carriage 13 pushes

bonnet lock hole

8a, 8b with dead bolt 12a, 12b, simultaneously, dead bolt stretches out self-locking mechanism 16 carriage 13 is pinned, and can't unblank by stirring dead bolt, reaches the anti-purpose of dialling of lockset.

By shown in Figure 3, dead bolt stretches out self-locking mechanism 16 and is installed on carriage 13 inboards, and pole 16b passes push rod 16a, triggers push rod 14 and is between pole 16b and the fixed bar 16d; Self-lock mechanism is: after carriage 13 was released dead bolt 12a, 12b fully, retainer 13a was under the push rod 16a, and push rod 16a enters retainer 13a under the effect of spring 16c elastic force, and carriage 13 is pinned, and carriage 13 can not be moved, and reached dead bolt and stretched out the self-locking purpose; Remove self-lock mechanism: promote to trigger push rod 14, by push rod inclined-plane 14a and fixed bar 16d pole 16b is upwards promoted, pole 16b drives push rod 16a and moves upward, after push rod 16a bottom surface height surpasses the upper level of carriage 13, by promoting dead bolt 12b movable support bracket 13 dead bolt is retracted in the lock box, reached the purpose of unblanking.Because of pull bar 17 is removed dead bolts to stretch out the principle of self-locking identical with triggering push rod 14, simple and clear in order to make schematic diagram, so the triggering push rod 14 that in Fig. 3, only draws.

Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, the utility model is described by implementation step.

1, locking state: locking state sees figures.1.and.2, and as shown in Figure 1, trigger board 5 is in its shift position foremost, and acrosome 4 is in its shift position rearmost end.Dead bolt 12a among Fig. 2,12b and contact 11a, 11b correspondence enter among bonnet lock hole 8a, the 8b, enter locking state.

2, the process of unblanking: keeper internally-powered mechanism need not any action when manually unblanking, at first remove the self-locking that dead bolt stretches out self-locking mechanism 16 by pulling lock box upper connecting rod 17, continue pulling pull bar 17 again, dead bolt 12a, 12b withdraws from

bonnet lock hole

8a, 8b, at last manually with Men Lakai, because under the tension of pull bar 17, though trigger board 5 hits contact 11a, but can not make dead bolt 12a, 12b stretches out, after the pulling force of pull bar 17 disappears, hook 21 on the carriage 13 hangs on the hanging column 19 automatically, provides condition for this lockset in the process of closing the door automatically locks, and manually unblanks to finish; The DC speed-reducing 1 of keeper is rotated during electronic unblanking, by gear 2, tooth bar 3 acrosome 4 is released, acrosome 4 will at first promote contact 11b, remove the self-locking that dead bolt stretches out self-locking mechanism 16, further promote dead bolt 12b again, movable support bracket 13, hook on the carriage 13 21 is colluded on hanging column 19, trigger board 5 moves to its rear end, position (away from the lock box position) under the effect of lever 7 simultaneously, prevents that contact 11a after hitting trigger board 5 ejects dead bolt in the process of opening the door.After acrosome 4 touches stopping means 6b, DC speed-reducing 1 will be reversed, and make acrosome 4 slow astern set a distances, prevent to hinder the unlatching of door, and its backway can be provided with by the reversing time of control DC speed-reducing 1, and electronic unblanking finished.

3, the process of locking: after electronic unblanking, the electronic lock electronic unit detects door and opens, and control DC speed-reducing 1 returns to locking state with acrosome 4, as shown in Figure 1 state; In the process of closing the door, contact 11a on the lock box will hit trigger board 5, the triggering push rod 24 that is connected with contact 11a promotes hook 21 makes it break away from hanging column 19, carriage 13 moves to keeper, dead bolt 12a, 12b are pushed among corresponding bonnet lock hole 8a, the 8b, and dead bolt stretches out self-locking mechanism 16 with carriage 13 pinnings simultaneously; 21 position restrictions of 26 pairs of hooks of block, spring 18 are shifted pull bar 17 onto and are prevented that foremost pull bar 17 from hindering the self-locking that dead bolt stretches out self-locking mechanism 16.
