The sliding frame 21 is a U-shaped frame, and is fixedly arranged on the inner wall of the casing 1, and the opening end of the sliding frame faces the through hole 11, so that the turning tongue 22 can turn in the sliding frame 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 turning tongue 22, and the other end of which is connected to the inner wall of the bottom surface of the slide frame 21. The first spring 23 applies a force to the inversion tongue 22 toward the outside of the housing 1, so that the inversion tongue 22 is located outside the housing 1 through the through hole 11. When the first spring bolt assembly 2 is applied to a door, the inclined surface of the turnover tongue 22 is extruded by a door frame to move into the sliding frame 21 in the door closing process, and meanwhile, the first spring 23 is pressed and accumulated, so that the turnover tongue 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 surface of the turning tongue 22, so that the turning tongue 22 turns in the sliding frame 21, and the side surface is applied by the door frame, and the acting force has a component force along the length direction of the first spring 23, so that the turning tongue 22 can be contracted into the shell 1, and the unlocking door opening is completed. In other words, the lock is locked by restricting the turning of the turning tongue 22. In order to enhance the stability of the first spring 23, a positioning strip 24 is provided in the longitudinal direction in the slide frame 21, the positioning strip 24 is provided across the slide frame 21 through a groove provided in the bottom surface of the slide frame 21, a positioning plate capable of abutting against the turning tongue 22 is provided at one end of the positioning strip 24 extending into the slide 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 an innovation point of the present invention, and thus will not be described in detail.

When the sliding plate 31 slides, the square tongue 32 can be driven to move in the through hole 11 and extend out of the shell 1 or retract into the shell 1. As shown in fig. 1b, a groove 33 is provided on the upper side of the sliding plate 31, a first limiting portion 34 recessed to the left is provided on the left side wall of the groove 33, and a second limiting portion 35 recessed to the right is provided on the right side wall of the groove 33, so as to be connected with the linkage assembly 4, so as to control the movement of the tongue 32. A strip hole is formed in the sliding plate 31 along the sliding direction of the square tongue 32, and a fixed shaft 12 penetrating through the strip hole is formed in the housing 1, so that the sliding direction of the sliding plate 31 can be limited, and the sliding distance of the sliding plate 31 can be limited, in other words, the length of the square tongue 32 extending out of the housing 1 can be controlled by controlling the length of the strip hole.

The linkage assembly 4 comprises a first poking block 41, a second spring 42, a second poking block 43 and a rotating wheel 44. The middle part of the first toggle block 41 is hinged on the housing 1, one end close to the sliding frame 21 is provided with a turnover tongue limiting block 411, and meanwhile, the side wall of the sliding frame 21 is provided with a hole for the turnover tongue limiting block 411 to penetrate. As shown in fig. 1a, when the first toggle block 41 rotates clockwise, the turning tongue limiting block 411 can penetrate into the sliding frame 21 to limit the turning of the turning tongue 22; when the first toggle block 41 rotates counterclockwise, the turning tongue limiting block 411 moves out of the slide frame 21, releasing the restriction on the turning tongue 22. The end of the first toggle block 41 far away from the sliding frame 21 is provided with a first support arm 412, and the first toggle block 41 is pushed to rotate by a bump on the rotating wheel 44.

In other embodiments, the second spring 42 may be a compression/extension spring, and the position of the second spring 42 may be changed by only ensuring that the second spring 42 applies a force to the first toggle block 41 and then moving the toggle latch block 411 into the slide frame 21.

One end of the second stirring block 43 is hinged in the shell 1, the other end is arranged in the groove 33 of the sliding plate 31, and the end of the second stirring block 43 can be switched between the first limiting part 34 and the second limiting part 35 by rotating the second stirring block 43. As shown in fig. 1b and 3b, when the second toggle block 43 rotates anticlockwise, the end of the second toggle block 43 moves to the right side and gradually approaches the right side wall of the groove 33, so as to push the slide plate 31 to move to the right side, and the square tongue 32 extends to the outside of the casing 1, thereby completing locking, and at this time, the end of the second toggle block 43 is located in the second limiting part 35; when the second toggle block 43 rotates clockwise, the end of the second toggle block 43 moves leftwards, gradually approaches the left side wall of the groove 33, pushes the sliding plate 31 to move leftwards, and enables the square tongue 32 to retract into the casing 1 to finish unlocking, and at the moment, the end of the second toggle block 43 is located in the first limiting part 34.

As shown in fig. 1a and 2, the first projection 441 is disposed on the left side of the second toggle block 43, and the second projection 442 is disposed on the right side of the second toggle block 43. When the rotating wheel 44 rotates anticlockwise, the first protruding block 441 pushes the second stirring block 43 to rotate anticlockwise, so that the square tongue 32 is brought into the shell 1, the locking of the second lock tongue assembly 3 is released, the second protruding block 442 abuts against the side surface of the first support arm 412, and the first stirring block 41 can be driven to rotate anticlockwise, so that the turnover tongue limiting block 411 moves out of the sliding frame 21, the limitation on the turnover tongue 22 is released, and the locking of the first lock tongue assembly 2 is released; when the rotating wheel 44 rotates clockwise, the second protruding block 442 first leaves the first support arm 412, the first toggle block 41 rotates clockwise under the action of the second spring 42, so that the turning tongue limiting block 411 moves into the sliding frame 21 to limit the turning tongue 22, and the first locking tongue component 2 is locked, and then the second protruding block 442 abuts against the side surface of the second toggle block 43 and pushes the second toggle block 43 to rotate clockwise, and the square tongue 32 is brought out of the housing 1, so that the second locking tongue component 3 is locked.

When the lock is used, the movement modes of the two lock tongue assemblies can be controlled simultaneously by controlling the linkage assembly 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 meshed with the gear are disposed on the periphery of the rotating wheel 44, so that the rotation direction and angle of the rotating wheel 44 can be controlled by the driving device 5, and further unlocking and locking of the lockset can be controlled. The drive 5 is in this embodiment of a motor plus transmission arrangement, the output of which is a gear wheel, although other known drive arrangements may be used. In another embodiment, the rotation of the rotatable wheel 44 may also be accomplished by a mechanical key and lock cylinder arrangement, with the rotation direction and angle of the rotatable wheel 44 controlled by the rotation of the key.

The above-mentioned figures show the structure, position and linkage relation of the first bolt component 2, the second bolt component 3 and the linkage component 4 in the lockset, and in other embodiments, the unlocking and locking of the lockset can be controlled by the linkage relation after the positions and detailed structures of the three components are changed, and the specific structure is not repeated.

In this embodiment, a controller, such as a PLC (programmable logic controller), for controlling the drive device 5 is also provided in the housing 1, and is communicatively connected to the drive device 5, 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 starts the driving device 5 to drive the rotating wheel 44 to rotate anticlockwise, so that the turning tongue limiting block 411 moves out of the sliding frame 21, the end of the second stirring block 43 moves into the first limiting part 34, and the square tongue 32 is driven to move into the housing 1 to complete unlocking; when the locking program is triggered, the controller opens the driving device 5 to drive the rotating wheel 44 to rotate clockwise, so that the second bump 442 leaves the first toggle block 41, and further the turning tongue limiting block 411 moves into the sliding frame 21 to limit the turning tongue 22, and the second bump 442 also pushes the end of the second toggle block 43 to move into the second limiting part 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 closed, the first protruding block 441 is far away from the left side of the second stirring block 43, so that when the lock is subsequently unlocked, the first protruding block 441 needs to move a certain distance before being abutted against the second stirring block 43, and further drives the second stirring block 43 to rotate to realize unlocking, and in this process, the rotating wheel 44 needs to idle for a certain time, so that the unlocking time is longer. Therefore, a third projection 443 is also provided on the side wall of the rotating wheel 44, and a sensing 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 bump 441 and the third bump 443, and may be a bi-directional switch, an infrared detector, a laser detector, or the like. In this embodiment, the sensing switch 6 is a two-way switch, which is communicatively connected to the controller, and when the first bump 441 abuts against the second toggle block 43, the third bump 443 abuts against the sensing switch 6. The reset program is preset in the controller, after the lock is closed, the third lug 443 is far away from the inductive switch 6, the reset program is started at the moment, the controller controls the rotating wheel 44 to rotate anticlockwise through the driving device 5, when the third lug 443 is abutted on the inductive switch 6, the rotating wheel 44 stops rotating, the first lug 441 is abutted on the second poking block 43 at the moment, and when the lock is subsequently unlocked, the driving device 5 can drive the square tongue 32 to rotate after being started, so that the unlocking time is shortened.

In addition, an authentication module and a location recognition module connected to the controller are provided in this embodiment. The identity verification module is used for verifying the identity of a user, and triggering the unlocking program to unlock after the identity verification of the user is passed; the position identification module is used for monitoring the position of the lockset, and when the lockset is in a locking position (such as a door closing state), the locking program is triggered to lock. The identity verification module can be realized through the prior art such as a password input module, a fingerprint identification module, a face identification module and the like, and the position identification module can be realized through the prior art such as a geomagnetic sensor, an accelerometer or a gyroscope and the like. For the occasion that the identity verification is not needed, the identity verification module can be omitted, for example, a door in a public area is omitted, the user does not need to conduct the identity verification when unlocking at one side in the door, and the unlocking program can be directly triggered through devices such as a switch. The position recognition module may be changed to a device such as a switch, and the unlocking program may be manually triggered.
