Example 1
As shown in fig. 1-2, the hand-pulled door lock 100 of the present embodiment includes a door frame 110 and a door lock mechanism, and a latch bolt hole is provided in the door frame 110. The door lock mechanism is installed in the door frame 110, and comprises a lock tongue 120 and a lock tongue driving device, wherein the lock tongue driving device comprises a deflector rod 130, a first electromagnet 140 and a second electromagnet 150, the first electromagnet 140 is provided with a first movable rod 141, and the second electromagnet 150 is provided with a second movable rod 151. The tip of the first lever 141 and the tongue 120 are connected to the lever 130, respectively. The first electromagnet 140 is vertically arranged, the lower part of the first movable rod 141 is provided with a groove 144, the second electromagnet 150 is horizontally arranged, and one end of the second movable rod 151, which faces the first movable rod 141, is provided with a protrusion 154 which can enter the groove 144 in the downward movement process of the first movable rod 141.
As shown in fig. 1 and 2, in a natural state of power failure, the first moving rod 141 moves upward under the action of the internal spring of the first electromagnet 140, and after power is obtained, the first moving rod 141 moves downward. In the natural state of power failure, the second moving rod 151 moves to the right direction in the figure, i.e. moves towards the first moving rod 141 under the action of the internal spring of the second electromagnet 150, and after power is obtained, the second moving rod 151 moves to the left direction in the figure, i.e. moves away from the first moving rod 141.
The hand-operated door lock 100 of the present embodiment further includes a first electromagnet control switch 142 and a second electromagnet control switch 152, and when the protrusion 154 enters the groove 144, the second movable rod 151 triggers the first electromagnet control switch 142 to de-energize the first electromagnet 140. After the first movable rod 141 moves upwards to drive the lock tongue to extend, the second electromagnet control switch 152 is triggered to enable the second electromagnet 150 to lose electricity. The second movable rod 151 is provided with a feeler lever 156 at one end thereof remote from the first movable rod 141.
The shift lever 130 includes a first connection block 132 and a second connection block 134, the latch 120 is mounted to the first connection block 132, and the top end of the first movable lever 141 is mounted to the second connection block 134.
The hand-operated door lock 100 of the present embodiment further includes a lever rotation shaft 160, and the lever 130 is mounted on the lever rotation shaft 160 and is rotatable about the lever rotation shaft 160.
The hand-operated door lock 100 of the present embodiment further includes a guide sleeve 122 that is fitted over the latch bolt.
The specific process is as follows: when the first electromagnet 140 is powered on, the first moving rod 141 moves downwards to drive the deflector rod 130 to move, the deflector rod 130 drives the lock tongue 120 to retract into the door frame 110, the elevator door is in an openable state at this time, and when the lock tongue 120 retracts into the door frame 110, the protrusion 154 of the second moving rod 151 enters the groove 144 of the first moving rod 141, at this time, the contact rod 156 of the second moving rod 151 triggers the first electromagnet control switch 142 to enable the first electromagnet 140 to be powered off, and the protrusion 154 of the second moving rod 151 enters the groove 144 of the first moving rod 141 to enable the first moving rod 141 to be locked in an upward movement, so that the lock tongue 120 is stably located in the door frame 110.
Then, when the second electromagnet 150 is powered on, the second moving rod 151 moves in a direction away from the first moving rod 141, so that the protrusion 154 of the second moving rod 151 withdraws from the groove 144 of the first moving rod 141, the first moving rod 141 moves upwards to drive the driving rod 130 to move, the driving rod 130 drives the locking bolt 120 to extend out of the door frame 110 from the locking bolt hole, at this time, the first connecting block 132 of the driving rod 130 triggers the second electromagnet control switch 152 to de-energize the second electromagnet 150, the second moving rod 151 moves in a direction towards the first moving rod 141, and because the groove 144 of the first moving rod 141 is located above the protrusion 154 of the second moving rod 151, the protrusion 154 cannot enter the groove 144, and the protrusion 154 abuts against the side surface of the lower end of the first moving rod 141. After the deflector rod 130 drives the lock tongue 120 to extend out of the door frame 110 from the lock tongue hole, the elevator door is in a non-openable state. The hand-operated door lock has the advantages of simple structure and good action reliability. In addition, the first electromagnet 140 and the second electromagnet 150 in this embodiment can be automatically powered off soon after being powered on, so that the service lives of the first electromagnet 140 and the second electromagnet 150 in this embodiment are longer.
Example 2
Substantially the same as in example 1, except that: the second movable lever 151 has a different structure for locking and unlocking the first movable lever 141, and a different structure for triggering the first electromagnet control switch 142.
One end of the second movable rod 151 facing the first movable rod 141 is connected with a clamping plate 256, and the clamping plate 256 can lock the first movable rod 141 when the first movable rod 141 is downward; when the second movable rod 151 moves away from the first movable rod, the catch plate 256 can unlock the first movable rod 141.
The card 256 is of an L-shaped structure, the card 256 includes a vertical portion and a horizontal portion, the horizontal portion of the card 256 is configured to lock the first movable rod 141, and when the horizontal portion of the card 256 locks the first movable rod 141, the vertical portion of the card 256 triggers the first electromagnet control switch 142 to de-energize the first electromagnet 140.
The horizontal portion of the card 256 is guided by a card guide block 258.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
