In this embodiment, intelligence fixed lock 100 still includes magnet steel 160, magnet steel 160 is fixed to be set up on set bar 130, magnet steel 160 is used for cooperating the use with the detection device on the control circuit 140, the detection device can adopt hall element or tongue tube, and when set bar 130 was in the blocking position, the detection device can detect magnet steel 160, and when set bar 130 was in the unblock position, the detection device then can't detect magnet steel 160, through communication module can send the status information of intelligence fixed lock 100 to the remote control end.

The normal unlocking process is as follows:

as shown in fig. 5-6, the control circuit 140 receives a remote unlocking command through the ZigBee communication network, the control circuit 140 supplies power to the solenoid, and after the solenoid is powered on, the mandrel 1262 retracts toward the tube 1261 by the electromagnetic induction principle, so as to avoid the movement path of the stopper pin 124.

At this time, the operator pulls the latch bolt 130 to move the latch bolt 130 in a direction away from the lock body 110, and the stopper screw 150 moves in the first stopper groove 1321 until it reaches the end (right end in the drawing) of the first stopper groove 1321, thereby restricting the moving range of the latch bolt 130, and at this time, the stopper pin 127 slides in the escape groove 133. As the latch 130 moves, the latching pin 122 gradually disengages from the latching groove 131 to move downward relative to the housing member 121, the lower end of the latching pin 122 presses the wedge surface of the stopper pin 124, and pushes the stopper pin 124 to move away from the latching pin 122 until the latching pin 122 completely disengages from the latching groove 131 and abuts on the outer circumferential surface of the latch 130.

When the latch 130 is moved fully to the unlatched position, the magnetic steel 160 is away from the hall element, the hall element cannot detect the magnetic steel 160, at which point the control circuit 140 no longer powers the drive element 126, and the spindle 1262 has a tendency to move toward the extended direction. And the whole unlocking process is completed.

The process of normal occlusion is as follows:

as shown in fig. 3 to 4, when the operator presses the latch bolt 130 to move the latch bolt 130 toward the lock body 110, the limit screw 150 moves in the first limit groove 1321 until reaching the initial end (left end in the figure) of the first limit groove 1321, and the stop pin 127 slides in the escape groove 133. As the latch 130 moves, the latching pin 122 moves upward relative to the housing member 121 into the latching groove 131 by the elastic force of the latching pin spring 123; the stopper pin 124 moves towards the closing direction of the locking pin 122 under the elastic force of the stopper pin spring 125 until the stopper pin 124 stops on the wall surface of the wedge-shaped hole of the housing assembly 121, at which time, the stopper pin 124 has completely exited the moving path of the mandrel 1262, and the mandrel 1262 can be extended out of the tube 1261 again to stop the moving path of the stopper pin 124. At this time, the latching pin 122 cannot disengage the latching slot 131 due to the stop of the spindle 1262, so that the latch 130 remains in the latched position. The whole locking process is completed.

The process of emergency unlocking is as follows:

as shown in fig. 7-8, the operator inserts the associated tool into the contoured configuration of the stop screw 150 to screw the stop screw 150 a distance away from the surface of the lock body 110. (it should be noted that, when the limit screw 150 is not screwed, that is, when the lock is normally unlocked, since the depth of the first limit groove 1321 is higher than the depth of the second limit groove 1323, the lower end of the limit screw 150 is always in the first limit groove 1321 and cannot enter the second limit groove 1323.) at this time, the operator rotates the lock bolt 130 by 90 °, and the limit screw 150 exits from the first limit groove 1321, passes through the connecting groove 1322, and enters the second limit groove 1323. Meanwhile, as the latch bolt 130 rotates, the blocking pin 127 gradually disengages from the avoiding groove 133 and moves downward relative to the housing assembly 121, and when the blocking pin 127 completely exits from the avoiding groove 133, the steel ball 129 presses the mandrel 1262, so that the mandrel 1262 completely exits from the retreating path of the stopper pin 124, and the steel ball 129 enters and stops on the retreating path of the stopper pin 124.

Then, the operator pulls the latch bolt 130 to move the latch bolt 130 away from the lock body 110, the limit screw 150 moves in the second limit groove 1323 until reaching the end of the second limit groove 1323, the latching pin 122 gradually disengages from the latching groove 131 and moves downward relative to the housing component 121 as the latch bolt 130 moves, the lower end of the latching pin 122 presses the wedge surface of the limit pin 124 and pushes the limit pin 124 to move away from the latching pin 122 until the latching pin 122 completely disengages from the latching groove 131 and abuts on the outer circumferential surface of the latch bolt 130. At the same time, the end of the stopper pin 124 gradually moves toward the steel ball 129, and as the stopper pin 124 moves, the stopper pin 124 presses and cuts the weak link structure between the stopper pin 127 and the steel ball 129, and the steel ball 129 moves under the push of the stopper pin 124 until the steel ball 129 falls into the accommodating hole 1213. And finishing the whole emergency unlocking process.

The emergency lockout procedure is as follows:

as shown in fig. 9, the operator presses the latch bolt 130 to move the latch bolt 130 toward the lock body 110, and the limit screw 150 moves in the second limit groove 1323 until reaching the initial end of the second limit groove 1323. As the latch 130 moves, the latching pin 122 moves upward relative to the housing member 121 into the latching groove 131 by the elastic force of the latching pin spring 123; the stopper pin 124 moves towards the closing direction of the locking pin 122 under the elastic force of the stopper pin spring 125 until the stopper pin 124 stops on the wall surface of the wedge-shaped hole of the housing assembly 121, at which time, the stopper pin 124 has completely exited the moving path of the mandrel 1262, and the mandrel 1262 can be extended out of the tube 1261 again to stop the moving path of the stopper pin 124. At this time, the latching pin 122 cannot disengage from the latching slot 131 due to the stop of the spindle 1262, thereby retaining the latch 130 in the latched position.

At this time, the operator rotates the latch 130 in the reverse direction by 90 °, and the limit screw 150 is withdrawn from the second limit groove 1323, passes through the connection groove 1322, and enters the first limit groove 1321. Meanwhile, as the latch bolt 130 rotates in the reverse direction, the stopper pin 127 moves upward relative to the housing assembly 121 under the elastic force of the stopper pin spring 128 and gradually enters the escape groove 133 until the stopper pin 127 completely enters the escape groove 133.

The operator inserts the related tool into the special-shaped structure of the limit screw 150, and completely screws the limit screw 150 in the special-shaped structure until the lower end surface of the limit screw 150 enters the first limit groove 1321 and cannot be removed. The whole emergency locking process is completed.

After the operator completes the emergency unlocking operation, the steel ball 129 falls into the accommodating hole 1213, the stopper pin 127 cannot be pressed onto the spindle 1262 again, and the spindle 1262 always stops on the movement path of the stopper pin 124, so the emergency unlocking operation cannot be performed again. But does not affect the normal unlocking operation.
