The sliding frame 21 is a U-shaped frame fixed on the inner wall of the housing 1, and the opening end of the U-shaped frame faces the through hole 11 for the turning tongue 22 to turn inside and slide along the length direction of the sliding frame 21. The first spring 23 is a compression spring, one end of which is connected to the flip tongue 22 and the other end of which is connected to the inner wall of the bottom surface of the sliding frame 21. The first spring 23 applies a force to the flip tongue 22 toward the outside of the housing 1 so that the flip tongue 22 is outside the housing 1 through the through hole 11. When the first latch bolt assembly 2 is applied to a door, in the door closing process, the inclined surface of the turning latch bolt 22 is extruded by the door frame to move towards the sliding frame 21, and meanwhile, the first spring 23 is pressed to store force, so that the turning latch bolt 22 is ejected out of the shell 1 by the first spring 23 after the door is closed; during the door opening process, the door frame presses the side of the turnover tongue 22, so that the turnover tongue 22 is turned inside the sliding frame 21, and the side of the turnover tongue 22 is subjected to the acting force exerted by the door frame, the acting force has a component force along the length direction of the first spring 23, so that the turnover tongue 22 can be contracted into the shell 1, and the unlocking and door opening are completed. In other words, the lock can be locked by restricting the turning of the turning tongue 22. In addition, in order to enhance the stability of the first spring 23, a positioning strip plate 24 is arranged in the sliding frame 21 along the length direction, the positioning strip plate 24 passes through a slot arranged on the bottom surface of the sliding frame 21 and is arranged on the sliding frame 21 in a spanning manner, a positioning plate capable of being abutted against the overturning tongue 22 is arranged at one end of the positioning strip plate 24 extending into the sliding frame 21, and the first spring 23 is connected to the positioning plate. In addition, the specific structure of the turning tongue 22 is prior art and is not the innovation point of the present invention, and therefore, the detailed description is not repeated.

When the rotating wheel 44 rotates counterclockwise, the first protrusion 441 pushes the second toggle block 43 to rotate counterclockwise, so as to bring the dead bolt 32 into the housing 1, and release the locking of the second bolt assembly 3, and the second protrusion 442 abuts against the side surface of the first support arm 412, so as to drive the first toggle block 41 to rotate counterclockwise, so that the flip bolt limiting block 411 moves out of the sliding frame 21, and release the limitation on the flip bolt 22, and then release the locking of the first bolt assembly 2; when the rotating wheel 44 rotates clockwise, the second protrusion 442 leaves the first support arm 412, the first toggle block 41 rotates clockwise under the action of the second spring 42, so that the toggle tongue limiting block 411 moves into the sliding frame 21 to limit the toggle tongue 22, and the first latch bolt assembly 2 is locked, and then the second protrusion 442 abuts against the side surface of the second toggle block 43 and pushes the second toggle block 43 to rotate clockwise, so that the square tongue 32 is brought out of the housing 1, and the second latch bolt assembly 3 is locked.

When the lockset is used, the movement modes of the two bolt components can be simultaneously controlled by controlling the linkage component 4, so that unlocking and locking are realized. In this embodiment, a driving device 5 is further disposed in the housing 1, the output end of the driving device is a gear, and teeth engaged with the gear are disposed on the periphery of the rotating wheel 44, so that the driving device 5 can control the rotating direction and angle of the rotating wheel 44, and further control the unlocking and locking of the lock. The drive means 5 is in this embodiment in the form of an electric motor plus a transmission, the output of which is a gear, although other known drive arrangements may be used. In another embodiment, the rotation of the rotator wheel 44 can also be achieved by a mechanical key and a key cylinder structure, and the rotation direction and angle of the rotator wheel 44 are controlled by rotating the key.

The structure, position and linkage relation of the first bolt assembly 2, the second bolt assembly 3 and the linkage assembly 4 in the lock are shown in the attached drawings, in other embodiments, the unlocking and locking of the lock can be controlled by the linkage relation after the positions and the detailed structures of the first bolt assembly, the second bolt assembly 3 and the linkage assembly are changed, and specific structures are not repeated.

In addition, in this embodiment, a controller, such as a PLC (programmable logic controller), for controlling the driving device 5 is provided in the housing 1, and the controller is connected to the driving device 5 in a communication manner, and an unlocking program and a locking program are preset in the controller. Referring to fig. 1a and fig. 2, when the unlocking procedure is triggered, the controller opens the driving device 5 to drive the rotating wheel 44 to rotate counterclockwise, so that the turning tongue limiting block 411 moves out of the sliding frame 21, the end of the second toggle block 43 moves into the first limiting portion 34, and the square tongue 32 is driven to move into the housing 1 to complete unlocking; when the locking procedure is triggered, the controller opens the driving device 5 to drive the rotating wheel 44 to rotate clockwise, so that the second protrusion 442 leaves the first moving block 41, the turning tongue limiting block 411 moves into the sliding frame 21 to limit the turning tongue 22, and the second protrusion 442 also pushes the end of the second moving block 43 to move into the second limiting portion 35 and drives the square tongue 32 to move out of the housing 1 to complete locking.

Referring to fig. 2, in this embodiment, when the lock is locked, the first protruding block 441 is far away from the left side of the second moving block 43, so that when the lock is unlocked subsequently, the first protruding block 441 can be abutted to the second moving block 43 only after moving a certain distance, and further the second moving block 43 is driven to rotate to unlock the lock, in this process, the rotating wheel 44 needs to idle for a certain time, so that the unlocking time is long. Therefore, a third projection 443 is further provided on the side wall of the rotary wheel 44, and an inductive switch 6 is provided in the housing 1 for detecting the position of the third projection 443. The inductive switch 6 is disposed between the first projection 441 and the third projection 443, and may be a two-way switch, an infrared detector, a laser detector, or the like. In this embodiment, the inductive switch 6 is a bidirectional switch, which is in communication connection with the controller, and when the first protrusion 441 abuts against the second toggle block 43, the third protrusion 443 abuts against the inductive switch 6. A reset program is preset in the controller, when the lock is closed, the third bump 443 is far away from the inductive switch 6, the reset program is started, the controller controls the rotating wheel 44 to rotate counterclockwise through the driving device 5, when the third bump 443 abuts against the inductive switch 6, the rotation of the rotating wheel 44 is stopped, at this time, the first bump 441 abuts against the second toggle block 43, and when the lock is subsequently unlocked, the driving device 5 is started to drive the square tongue 32 to rotate, so that the unlocking time is reduced.

The identity authentication module can be realized by the prior art such as a password input module, a fingerprint identification module, a face recognition module and the like, and the position identification module can be realized by the prior art such as a geomagnetic sensor, an accelerometer or a gyroscope and the like. For the occasion without identity authentication, the identity authentication module can be cancelled, for example, a door in a public area, and the user does not need identity authentication when unlocking at one side in the door, so that an unlocking program can be directly triggered by a switch and other devices. The position recognition module can be changed into a switch or other devices, and the unlocking program is triggered manually.

In addition, in this embodiment, a third spring 45 is further provided, please refer to fig. 1b and fig. 3b, the third spring 45 is a torsion spring, one end of which is hinged to the housing 1, and the other end of which is hinged to the end of the second toggle block 43. A cylindrical connecting shaft is arranged at the end of the second toggle block 43, and the other end of the third spring 45 is sleeved on the connecting shaft.

Therefore, the lock can be in a stable locking state and an unlocking state.

The intelligent lockset can be controlled to unlock and lock in an electric mode. In order to avoid the situation that the lock cannot be unlocked due to circuit failure, in the embodiment, a structure capable of being unlocked by a mechanical key is also arranged. Referring to fig. 3a to fig. 6, an extended second arm 413 is further disposed at an end of the first toggle block 41 away from the flip tongue limiting block 411, and the second arm 413 extends downward in the drawing.
