Alternatively, the positioning member 470 may be a stop pin, a stopper, or the like.
In the door lock 500, it is necessary to manually open the landing door outside the landing door by inserting the key into the cylinder 520 and rotating the key to push the trigger 510 to open the trolley 480. In a conventional state, the first connecting rod 410, the second connecting rod 420, the third connecting rod 430 and the fourth connecting rod 440 are matched to form a square structure, when the trigger 510 pushes the trigger 480 to open, the first connecting rod 410, the second connecting rod 420, the third connecting rod 430 and the fourth connecting rod 440 are transformed into a parallelogram structure, so that the fourth connecting rod 440 moves towards a direction close to the second layer door 210, and the locking member 450 and the limiting member 460 complete locking as the key continues to be screwed. That is, the door opening protection device must be locked every time the elevator landing door is opened by the key, and the door opening protection device does not act because the touch piece 510 is not touched when the elevator landing door is opened and closed electrically at ordinary times.
As shown in fig. 1-4, the working principle of the elevator landing door in the present embodiment is as follows:
when the door lock 500 is manually opened outside the landing door when the landing door is closed (see fig. 1), the touch member 510 is first pressed against the opening touch wheel 480, and the first connecting rod 410, the second connecting rod 420, the third connecting rod 430 and the fourth connecting rod 440 are transformed into a parallelogram structure, so as to push the locking member 450 to be in locking connection with the limiting member 460, thereby locking the door opening protection device (see fig. 2). As the key is further turned, the trigger 510 rotates continuously, the trigger 510 is tangent to the outer circle of the opening trolley 480 (as shown in fig. 3), and when the trigger 510 rotates continuously, the trigger 510 is separated from the opening trolley 480, and then the trigger 510 pushes the shift lever 330 to separate the first locking member 450 from the second locking member 450, so that the landing door lock 300 is unlocked (as shown in fig. 4). Since the door-opening protection device is locked, the elevator landing door cannot be completely opened, and the limiting member 460 and the locking member 450 interfere with each other in the process of opening the elevator landing door, so that the parallelogram continues to deform. If the operating personnel outside the elevator landing door ensures that the elevator can safely enter the elevator car, the locking piece 450 can be manually lifted, the parallelogram restores to be square under the action of the first elastic restoring piece 490, and the locking piece 450 restores to be capable of directly opening the elevator landing door.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
