Currently, the anti-theft lock is widely applied to doors in various occasions due to high safety. Various anti-theft locks are available on the market, for example: conventional anti-theft locks, coded lock type anti-theft locks, fingerprint lock type anti-theft locks, and the like. The coded lock type anti-theft lock and the fingerprint lock type anti-theft lock can achieve the functions of automatic unlocking and automatic locking, and the conventional anti-theft lock is manually unlocked and locked through a key. For newly decorated occasions, the functions of automatic unlocking and automatic locking can be realized by directly installing the coded lock type anti-theft lock and the fingerprint lock type anti-theft lock. For the door installed with the conventional anti-theft lock, in order to have the functions of automatic unlocking and automatic locking, the whole anti-theft lock or the whole door can only be replaced, but because the shapes and the sizes of the lock bodies of the anti-theft locks of users are different, the new lock body and the old lock body are not matched frequently, the opening and the slotting on the door are required to be changed on site, the replacement is complex, the workload is large, and the cost is high.

Therefore, the unlocking and locking robot is a device which is installed on the anti-theft lock of the door and automatically unlocks and locks the anti-theft lock, the whole anti-theft lock or the whole door does not need to be replaced, and the unlocking and locking robot only needs to be installed on the conventional anti-theft lock, so that the anti-theft lock has the functions of automatic unlocking and automatic locking, and the device is convenient to install, small in workload and low in cost. The existing unlocking and locking robot comprises a shell main body, a connector and a motor. The shell main body is arranged on the anti-theft lock or the door, the connector is rotatably connected with the shell main body, and the connector is connected with the opening and closing lock knob of the anti-theft lock. The motor is arranged in the shell main body and drives the connector to rotate forwards or backwards, so that the opening and closing lock knob of the anti-theft lock is driven to rotate forwards or backwards, and the functions of automatic unlocking and automatic locking of the anti-theft lock are realized.

However, the existing unlocking and locking robot cannot be manually unlocked and locked, and people can only let the unlocking and locking robot drive the anti-theft lock to automatically unlock and lock for several seconds, such as outside a door or inside the door, which can cause waiting time for people, thereby causing discomfort. Because the switching lock knob of pickproof lock passes through coupling mechanism and motor shaft and links to each other, if manual opening by force, shutting can twist and open the shutting knob and rotate, motor shaft is quiescent condition this moment, twists switching lock knob and can drive motor shaft and then rotate by force, and the atress is big, causes motor wearing and tearing or damage easily, greatly reduces the life of motor.

The link member 430 and the drawing member 440 are installed in the cylindrical installation groove 411.

Referring to fig. 6 and 7, when the driving mechanism 500 operates, the driving mechanism 500 drives the swing arm 420 to rotate around the output end of the driving mechanism 500 in the cylindrical mounting groove 411, so that the swing arm 420 pushes the linkage piece 430 to move, the linkage piece 430 is partially accommodated in the linkage groove 412 under the action of the pushing force and the centrifugal force of the swing arm 420, and the part of the linkage piece 430 extending out of the linkage groove 412 abuts against the swing arm 420, so that the swing arm 420, the linkage piece 430 and the clutch main part 410 abut against one another in sequence, and the output end of the driving mechanism 500 is in transmission connection with the clutch main part 410, thereby driving the clutch main part 410 to rotate. In the unlocking and locking robot, the clutch master 410 rotates to drive the unlocking and locking knob of the anti-theft lock to rotate through the transmission mechanism 300 and the connecting mechanism 200, so that the anti-theft lock is automatically unlocked and locked.

Referring to fig. 6 and 7, when the driving mechanism 500 is stopped, the drawing member 440 draws the link member 430 out of the link groove 412. At this time, the clutch main 410 is drivingly connected to the swing arm 420, and thus the clutch main 410 is drivingly connected to the output end of the driving mechanism 500. The unlocking and locking knob is turned by hand or a key, the unlocking and locking knob drives the clutch main part 410 to rotate, transmission between the clutch main part 410 and the output end of the driving mechanism 500 is released, and therefore only the clutch main part 410 rotates along with the clutch main part, the rotating shaft of the driving mechanism 500 cannot rotate along with the clutch main part, the driving mechanism 500 cannot be abraded or damaged, and the service life of the driving mechanism 500 is prolonged.

Preferably, four linkage grooves 412 are formed in the linkage groove 412, and the four linkage grooves 412 are annularly and uniformly distributed on the side wall of the cylindrical mounting groove 411, so that the swing arm 420 can be pushed to be rapidly connected with one linkage groove 412 when rotating, and the transmission efficiency is improved.

In another embodiment of the present invention, referring to fig. 6 and 7, at least one of the linkage member 430 and the pulling member 440 is made of a magnet, and the other is made of a magnet or a metal to which the magnet is attached. The link member 430 is magnetically attracted to the drawing member 440 so that the drawing member 440 can draw the link member 430 out of the link groove 412 when the driving mechanism 500 is stopped.

Specifically, in some embodiments, the linkage 430 and the pulling member 440 are made of magnets, the pulling member 440 is fixedly installed in the middle of the cover 450, and the pulling member 440 is smaller or slightly smaller than the cylindrical installation slot 411.

Specifically, the length of linkage 430 and the degree of depth adaptation of cylindrical mounting groove 411 for linkage 430 can move in cylindrical mounting groove 411 steadily, avoids linkage 430 to take place askew at the removal in-process, guarantees stable in structure.

In some embodiments, the linkage member 430 has a spherical shape, and accordingly, the linkage groove 412 has a hemispherical shape adapted to the linkage member 430, so that the linkage member 430 can be stably and partially received in the linkage groove 412. Specifically, the diameter of the link 430 is adapted to the depth of the cylindrical mounting groove 411, so that the link 430 can stably move in the cylindrical mounting groove 411, and the movement stability is good.

Specifically, the cross section of the linking groove 412 is semicircular or smaller than semicircular, and the center of the cross section of the linking groove 412 is located in the cylindrical mounting groove 411, so that the linking member 430 can effectively extend into the linking groove 412 to be matched with the linking groove 412.

In another embodiment of the present invention, referring to fig. 6 and 7, a cylindrical mounting groove 411 extends to an end of the engaging main member 410 and forms an opening, and a closing member 410 is adapted to close the opening, so that the cylindrical mounting groove 411 forms a closed cavity, facilitating the mounting of the link member 430, the swing arm 420 and the pulling member 440. Specifically, in the present embodiment, the cover element 410 is fixedly installed on the driving mechanism 500, and the cover element 410 is rotatably connected with the clutch main element 410. The output end of the driving mechanism 500 is movably inserted through the cover 410 and into the center of the cylindrical mounting groove 411.

Further, referring to fig. 6 and 7, a drawing member mounting groove 451 is dug in the middle of the end surface of the cover member 450 located in the cylindrical mounting groove 411, the drawing member 440 is fittingly received in the drawing member mounting groove 451, and the end surface of the drawing member 440 is flush with the end surface of the cover member 450. The pulling member 440 may be fixed to the cover 450 by interference clamping, bonding, or the like.

Further, the drawing member 440 has a circular shape, and the diameter of the drawing member 440 is smaller than that of the cylindrical mounting groove 411, ensuring that the drawing member 440 can draw the link member 430 completely away from the link groove 412.

In another embodiment of the present invention, referring to fig. 4 and 5, the drive mechanism 500 is a motor. The rotating shaft 510 of the motor passes through the center of the cover 450 and extends into the center of the cylindrical mounting groove 411, and the swing arm 420 is fixedly mounted on the rotating shaft 510 of the motor.

In some embodiments, the swing arm 420 is a swing block, one end of which is fixedly mounted on the rotating shaft 510 of the motor, and the other end of which is proximate to the inner circumferential wall of the cylindrical mounting groove 411.
