[0019] like Figure 1-Figure 4As shown, this embodiment provides a locking mechanism of a lock, which can be applied to locks such as indoor door locks, padlocks, glass door locks, U-shaped locks and chain locks. The locking mechanism includes a lock box 1 and a lock body 2 arranged relatively to each other. The lock box 1 can be set on the fixed door body of the glass door, and the lock body 2 can be set on the movable door body of the glass door; or the lock box 1 can be set on the movable door body of the glass door, and the lock body 2 can be set on the fixed door body of the glass door, and the movable door body can be driven to rotate relative to the fixed door body by external force, so that the lock box 1 and the lock body 2 are moved closer to or away from each other.

[0020] like Figure 1 As shown, the lock box 1 is provided with a locking groove 3, which faces the lock body 2. The lock body 2 is provided with a limiting channel, a diamond-shaped lock tongue 4, a stopper and a driving mechanism 5. The diamond-shaped lock tongue 4 is movably arranged in the limiting channel. The limiting channel has a limiting function for the diamond-shaped lock tongue 4. The diamond-shaped lock tongue 4 in the limiting channel can rotate within a certain angle range. The diamond-shaped lock tongue 4 can extend or retract into the lock body 2. The middle part of the diamond-shaped lock tongue 4 is provided with a rotating shaft 6. Figure 4 As shown, the lock body 2 is provided with a strip-shaped limiting slot 7, which allows the rotating shaft 6 to slide, allowing the diamond-shaped lock tongue 4 to slide along the limiting channel and extend into or out of the locking slot 3. The diamond-shaped lock tongue 4 is equipped with a return spring, which is used to drive the diamond-shaped lock tongue 4 back to its original position. The diamond-shaped lock tongue 4 can slide and rotate when subjected to external force within the lock body 2. When the external force is removed, it can return to its original position under the action of the return spring.

[0021] like Figure 1 and Figure 2 As shown, the driving mechanism 5 is used to drive the stopper toward the diamond-shaped lock tongue 4 to lock it, and to drive the stopper away from the diamond-shaped lock tongue 4 to unlock it, so that the diamond-shaped lock tongue 4 can rotate and slide and disengage the locking groove 3. When the stopper abuts one end of the diamond-shaped lock tongue 4, the diamond-shaped lock tongue 4 cannot slide directly. When the diamond-shaped lock tongue 4 is subjected to an external force, it can rotate upward. After the diamond-shaped lock tongue 4 is disengaged from the stopper, it can slide along the limiting slide groove 7. After the external force is removed, the return spring can drive the diamond-shaped lock tongue 4 back to its original position. When the stopper moves away from the diamond-shaped lock tongue 4, the diamond-shaped lock tongue 4 is unlocked and no longer restricted. It can slide along the limiting slide groove 7 and rotate within a certain angle range.

[0022] like Figure 1-Figure 3As shown, the locking mechanism has a locked state, an unlocked state, and an anti-locked state. When the locking mechanism is in the locked state, the lock body 2 and the lock box 1 are opposite each other. The driving mechanism 5 drives the stopper to contact one end of the diamond-shaped lock tongue 4, and the other end of the diamond-shaped lock tongue 4 extends into the locking groove 3, thereby locking the lock box 1 and the lock body 2. The movable door body and the fixed door body remain in the locked state. The locking mechanism is in the unlocked state. The lock body 2 and the lock box 1 are opposite each other. The driving mechanism 5 drives the stopper away from the diamond-shaped lock tongue 4 to unlock it. After the diamond-shaped lock tongue 4 is no longer restricted, it can rotate and slide, thereby unlocking the lock box 1 and the lock body 2. The movable door body and the fixed door body can be unlocked and separated by simply rotating the movable door body.

[0023] When the locking mechanism is in the reverse locking state, the lock body 2 and the lock box 1 are initially separated, and the driving mechanism 5 drives the stopper to lock the diamond-shaped lock tongue 4. The lock box 1 is driven by external force to rotate relative to the lock body 2, that is, the movable door body gradually approaches the fixed door body, and the lock box 1 gradually approaches the lock body 2 and applies pressure to the diamond-shaped lock tongue 4. One end of the diamond-shaped lock tongue 4 is blocked by the stopper, and one end of the diamond-shaped lock tongue 4 is pressed by the lock box 1, so that the diamond-shaped lock tongue 4 can rotate in one direction by a certain angle. When the locking groove 3 approaches the diamond-shaped lock tongue 4, the diamond-shaped lock tongue 4 rotates back to its original position under the action of the return spring, and the diamond-shaped lock tongue 4 extends into the locking groove 3, realizing the reverse locking of the lock box 1 and the lock body 2. At this time, the diamond-shaped lock tongue 4 returns to the state pressed by the stopper, realizing keyless reverse locking.

[0024] The present invention has a simple structure, low cost, stable and reliable use, can be locked without a key, password or fingerprint, and improves user convenience.

[0025] In this embodiment, the stopper includes a stop block 8, which is slidably disposed within the limiting channel. The drive mechanism 5 is connected to the stop block 8. The drive mechanism 5 can drive the stop block 8 to slide, causing the stop block 8 to move closer to or further away from the diamond-shaped lock tongue 4. Preferably, the end of the stop block 8 that is adjacent to the diamond-shaped lock tongue 4 is provided with a stop surface, which is configured to contact the corner of the diamond-shaped lock tongue 4. When the drive mechanism 5 drives the stop block 8 toward the diamond-shaped lock tongue 4, the stop surface can contact the corner of the diamond-shaped lock tongue 4, thereby achieving the locking function of the diamond-shaped lock tongue 4.

[0026] In one embodiment, the drive mechanism 5 includes a key drive assembly, the movable end of which is connected to a stop block 8. A key can be inserted into the key drive assembly. To unlock the door, the key is turned, which, through the key drive assembly, causes the stop block 8 to slide leftward or downward, moving it away from the diamond-shaped lock tongue 4. Once the diamond-shaped lock tongue 4 is freed from restraint, it can rotate and slide. It should be noted that the key and key drive assembly are currently mature technologies and will not be described further.

[0027] In a specific embodiment, the driving mechanism 5 includes a push rod motor, the movable end of which is connected to the stop block 8, the push rod motor is connected to a controller, and the controller is connected to a communication module. Preferably, the lock body 2 is provided with a fingerprint acquisition module and a password input module, both of which are connected to the controller. The fingerprint acquisition module and the password input module are used to control the push rod motor, causing the stop block 8 to slide to the left or downward to move away from the diamond-shaped lock tongue 4, thereby achieving the unlocking function. It should be noted that the push rod motor, controller, communication module, fingerprint acquisition module, and password input module are all existing mature technologies and are therefore not described further.

[0028] In this embodiment, the corners of the diamond-shaped lock tongue 4 are all rounded. The rotating shaft 6 is fixed to the diamond-shaped lock tongue 4. Both ends of the rotating shaft 6 extend to the outside of the diamond-shaped lock tongue 4 and slide into the limiting slide 7. The length of the limiting slide 7 is the length of the diamond-shaped lock tongue 4 when it is retracted into the lock body 2.

[0029] This embodiment also provides a method for using the locking mechanism of a lock, including: Lock status: Figure 1 As shown, the lock body 2 and the lock box 1 are opposite to each other, that is, the fixed door body and the movable door body are opposite to each other, and the driving mechanism 5 drives the stop block 8 to approach the diamond-shaped lock tongue 4 to lock it, and the diamond-shaped lock tongue 4 extends into the locking groove 3 to achieve the locking of the lock box 1 and the lock body 2; Unlock status: Figure 2 As shown, the lock body 2 and the lock box 1 are opposite to each other, that is, the fixed door body and the movable door body are in a locked state, and the driving mechanism 5 drives the stop block 8 away from the diamond-shaped lock tongue 4 to unlock it. The diamond-shaped lock tongue 4 loses its restriction and can rotate and slide, thereby unlocking the lock box 1 and the lock body 2; Anti-lock status: Figure 3 As shown, the lock body 2 and the lock box 1 are separated, and the driving mechanism 5 drives the stop block 8 to lock the diamond-shaped lock tongue 4. The lock box 1 is driven by external force to rotate relative to the lock body 2. The lock box 1 gradually approaches the lock body 2 and applies pressure to the diamond-shaped lock tongue 4, causing the diamond-shaped lock tongue 4 to rotate in one direction by an angle. When the locking groove 3 approaches the diamond-shaped lock tongue 4, the diamond-shaped lock tongue 4 returns to its original position under the action of the return spring, and the diamond-shaped lock tongue 4 extends into the locking groove 3, thereby realizing the anti-locking of the lock box 1 and the lock body 2.

[0030] The invention is simple and convenient to operate, can realize free locking, realizes the anti-locking function without a key, a password and a fingerprint, and cannot be unlocked at will, thereby improving the safety of the lock.
