Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1-2, the manual and electric integrated external unlocking device is connected with other parts through an external operating bracket 4, and a sliding end cover 2, a lock cylinder sleeve 3 and a connecting sleeve 15 are arranged at the front end of a lock cylinder 1. Install compression spring 12 between slip end cover 2 and lock core 1, compression spring 12 guarantees that slip end cover 2 flushes with lock core 1, and when using the key to insert lock core 1, slip end cover 2 is pushed down, and the key rotates with lock core 1 synchronization. An O-shaped sealing ring 13 is arranged between the lock cylinder sleeve 3 and the outer operating bracket 4, and an O-shaped sealing ring 14 is arranged between the lock cylinder 1 and the shaft sleeve 11. The external operating bracket 4 is provided with a shaft sleeve 11, and the shaft sleeve 11 is connected with the lock cylinder 1. The microswitch 9 is connected with the outer operating bracket 4 through a cross slot screw 10. The collision bead 6 is connected with the outer operating bracket 4 through a thin nut 5, and the collision bead can be replaced by a stop hook. The backing plate 20 is installed between the lock cylinder 1 and the switch striking block 8. The end part of the lock core 1 is provided with a large gasket 17, a butterfly gasket 18 and a hexagon nut 19, which play a role in fixing the whole device.
As shown in fig. 3, the lock cylinder 1 is connected, and the wire grip 7 always rotates synchronously with the lock cylinder 1. The switch striking block 8 is internally provided with a reset torsion spring 16. The cylindrical pin 21 is fixed with the guy plate 7, and the part of the cylindrical pin 21 extending out of the guy plate 7 is inserted into the long waist hole of the switch collision block 8. Since the cylindrical pin 21 is in contact with the upper edge of the long waist hole of the switch striking block 8 in the initial position. If the lock cylinder 1 rotates anticlockwise, the lock cylinder 1 drives the wire drawing disc 7 to rotate anticlockwise, and the cylindrical pin 21 rotates anticlockwise to drive the switch collision block 8 to rotate anticlockwise. If the lock core 1 rotates clockwise, the lock core 1 drives the anchor plate 7 to rotate clockwise, the cylindrical pin 21 slides in the long waist hole of the switch collision block 8, and the switch collision block 8 is static at the moment.
As shown in fig. 4, when the door is electrically opened and closed by adopting the invention, the key is used for rotating the lock cylinder 1 in the counterclockwise direction, the lock cylinder 1 drives the wire drawing disc 7 and the switch collision block 8 to rotate counterclockwise, at the moment, the collision ball 6 is separated from the first positioning groove, and after the rotation to a certain angle, the switch collision block 8 can trigger the microswitch 9. After the micro switch 9 is triggered, a door opening and closing signal is given to the door controller, and if the door system is closed at the moment, the door opening action is triggered; if the door system is opened at this moment, the door closing action can be triggered, and the electric door opening and closing of the door system is realized. After the microswitch 9 is triggered, if the lock cylinder 1 drives the switch collision block 8 to continue to rotate anticlockwise, the surface A of the switch collision block 8 touches the surface B of the outer operating support 4, so that the position limitation of the lock cylinder 1 during anticlockwise rotation is realized, after a key is loosened, the switch collision block 8, the anchor plate 7 and the lock cylinder 1 are automatically reset under the action of the reset torsion spring 16, and finally the anchor plate 7 is positioned by the collision bead 6 after rotating to the first positioning groove 22 and is restored to the initial position.
As shown in figure 5, when the door is manually opened and closed by adopting the invention, the key is used for rotating the lock core 1 clockwise, the lock core 1 drives the wire drawing disc 7 to rotate clockwise, the switch collision block 8 keeps static, and the collision bead 6 is separated from the positioning groove. When the anchor plate 7 rotates clockwise, the steel wire rope is tensioned, so that the door system is unlocked, and manual opening of the door can be realized. The anchor plate 7 rotates clockwise, when the cylindrical pin 21 rotates clockwise to the edge of the lower part of the long waist hole of the switch collision block 8, the surface C of the switch collision block 8 touches the surface D of the outer operating support 4, the lock core 1 rotates clockwise, the position is limited, and after the key is loosened, the anchor plate 7 rotates to the second positioning groove 23 under the action of the tension force of the steel wire rope and is positioned by the collision bead 6. The anchor 7 can not reset to the initial position automatically, must use the key to rotate lock core 1 and carry out manual reset, and final anchor 7 is fixed a position by bumping ball 6 after rotating to first constant head tank, resumes to the initial position.
