[0038] The following is combined with Figure 1-7 This application is described in further detail.

[0039] The embodiments of the present application disclose a linkage structure and a smart lock.

[0040] Example 1

[0041] Reference Figure 1-6 A linkage structure and a smart lock include a front panel 1, a rear panel 2 is fixedly installed at the rear end of the front panel 1 by a plurality of screws, an outer handle 3 is rotatably installed inside the front panel 1, and an inner handle 4 is rotatably installed inside the rear panel 2. Specifically, a rotation window is provided on the outer wall of the front panel 1 and the rear panel 2, and the outer handle 3 and the inner handle 4 pass through the front panel 1 and the rear panel 2 respectively through the rotation window. A lock body structure for achieving a door locking effect is movably installed inside the front panel 1 and the rear panel 2, and a locking structure for an auxiliary device to lock the door is installed on the right side of the lock body structure (please refer to Figure 5 ), an anti-locking structure for further enhancing the safety of the device is movably installed inside the rear panel 2 above the lock body structure; specifically, the outer handle 3 and the inner handle 4 are fixedly connected by bolts.

[0042] Please refer to Figure 5 The lock body structure includes a square shaft 5, which is rotatably installed between the front panel 1 and the rear panel 2, and the two ends of the square shaft 5 are respectively clamped with the outer handle 3 and the inner handle 4. Specifically, the ends of the outer handle 3 and the inner handle 4 that are close to each other are each provided with a square groove adapted to the square shaft 5, and the square shaft 5 is inserted into the square groove. A movable frame 501 for driving the lock body structure to operate is rotatably installed on the outside of the square shaft 5, and a lock tongue 502 is movably installed on one left side of the movable frame 501.

[0043] Specifically, a rotating block 503 is fixedly installed on the outer wall of the square shaft 5, and the rotating block 503 is rotatably connected to the inside of the mobile frame 501. A rotating groove for rotating the rotating block 503 is opened inside the mobile frame 501. The rotating block 503 is connected to the square shaft 5 to drive the mobile frame 501 to control the telescopic movement of the lock tongue 502.

[0044] Please refer to Figure 5 The locking structure includes a push plate 6, which is installed on the side of the mobile frame 501 away from the lock tongue 502. The mobile frame 501 can be quickly pushed to reset through the setting of the push plate 6. The internal rotation of the push plate 6 is installed with an axle rod 601, and the side of the push plate 6 away from the mobile frame 501 is fixedly installed with a thrust spring 602 for providing power to the push plate 6.

[0045] Specifically, the distances between the upper and lower ends of the moving frame 501 close to the push plate 6 are different. Figure 5 Specifically, the distance between the upper side of the moving frame 501 and the pushing plate 6 is smaller than the distance between the lower side of the moving frame 501 and the pushing plate 6.

[0046] Through the above arrangement, when the movable frame 501 moves toward the push plate 6, the push plate 6 rotates and tilts around the shaft rod 601, thereby squeezing the thrust spring 602. When the door is opened and the control of the movable frame 501 is released, the thrust spring 602 pushes the movable frame 501 in the opposite direction, driving the lock tongue 502 to move to a state of extending and locking the door, so as to achieve rapid initial locking of the device, effectively preventing the lock body structure from being opened by the outer handle 3 after the door is closed, preventing tailgating incidents, achieving a safety precaution effect, and ensuring the safety of the device.

[0047] See also Figure 6 The locking structure also includes a driving motor 603, a mounting end of the driving motor 603 is fixed with a bearing plate, and the bearing plate is fixedly connected to the side wall of the fixing box 7, and a threaded rod 604 is mounted on the output end of the driving motor 603 through a coupling, and a movable part 605 that can rotate with the threaded rod 604 is fixedly mounted on the outer wall of the threaded rod 604, and an upward spring 606 is fixedly mounted inside the movable part 605. Specifically, a sleeve is provided at the upper end of the movable part 605, and the upward spring 606 is located inside the sleeve, and an insert block 607 for final positioning of the square shaft 5 is slidably mounted inside the sleeve, and a slot for inserting the insert block 607 is provided at the bottom end of the square shaft 5;

[0048] Specifically, by inserting the insert block 607 into the interior of the square shaft 5 through the above-mentioned setting, the operation state of the outer handle 3 rotating to unlock is further restricted, thereby enhancing the safety of the device. The insert block 607 is installed at the axis of the entire device to effectively prevent damage by external forces, reduce safety hazards, and maintain the normal use of the device.

[0049] See also Figure 5 , 6 The outer wall thread sleeve of the threaded rod 604 is provided with a pulling plate 608 for driving the push plate 6 to reset, and one side of the pulling plate 608 is fixedly connected to the shaft 601, and a square groove for providing sliding of the pulling plate 608 is opened on the side of the positioning cover 508 close to the pulling plate 608.

[0050] The implementation principle of a linkage structure and an intelligent lock in the embodiment of the present application is as follows: by pressing down the outer handle 3 connected to the square shaft 5 to drive the rotating block 503 to rotate, the movable frame 501 drives the pushing plate 6 to tilt and rotate around the shaft rod 601, and squeezes the thrust spring 602. When the pressure on the outer handle 3 is released, the thrust spring 602 connected to the pushing plate 6 pushes the movable frame 501 in the opposite direction to drive the lock tongue 502 to reset, and preliminarily limits the movable frame 501, so that the outer handle 3 cannot continue to rotate, and the door is automatically locked after closing. At the same time, the driving motor 603 is started to connect the threaded rod 604 to drive the movable part 605 to move to the bottom end of the square shaft 5. Under the action of the upward spring 606, the insert block 607 is pushed to be inserted into the inside of the square shaft 5, so that it cannot rotate, and the device is finally locked, thereby effectively preventing the incident of following the crime and enhancing the safety performance of the device. In addition, when the threaded rod 604 rotates, it drives the pulling plate 608 connected to the pushing plate 6 to reset away from the movable frame 501 to facilitate repeated operation.

[0051] Example 2

[0052] Reference Figure 4-6 The difference between this embodiment and the first embodiment is that a connecting frame 504 is fixedly installed on one end of the locking tongue 502 close to the square shaft 5, a protruding block 505 is fixedly installed on one side of the movable frame 501 close to the locking tongue 502, and one side of the connecting frame 504 is mutually clamped with the protruding block 505. Specifically, a clamping window corresponding to the protruding block 505 is opened in the middle of the connecting frame 504, and the protruding block 505 is clamped with the protruding block 505 through the clamping window. In order to facilitate the reset of the locking tongue 502, a fixing tube 506 is sleeved on the outside of the connecting frame 504, and a reset spring 507 is fixedly installed inside the fixing tube 506, and one end of the reset spring 507 is fixedly connected to the locking tongue 502. 。

[0053] Through the above-mentioned arrangement, a sliding groove is opened inside the connecting frame 504 for providing sliding of the protruding block 505, and a movable groove is opened inside the fixed tube 506 to facilitate the movement of the locking tongue 502 and the connecting frame 504 inside the fixed tube 506. There are three groups of locking tongues 502 in total and they are symmetrically and evenly distributed to further enhance the tight fit between the device and the door frame and ensure the stability of the device.

[0054] The outer sleeve of the movable frame 501 is provided with a positioning cover 508 for limiting and fixing the movable frame 501, and the movable frame 501 and the push plate 6 are located in the positioning cover 508, the square shaft 5 passes through the interior of the positioning cover 508, and the outer part of the positioning cover 508 is fixedly installed with a fixing box 7 for installing the lock body structure, and the fixing box 7 is fixedly installed inside the front panel 1 and the rear panel 2 by bolts, and the fixing tube 506 is fixedly installed inside the fixing box 7.

[0055] Reference Figure 7 The anti-locking structure includes a knob 8, which is rotatably mounted on the middle part of one side of the rear panel 2. A rotating rod 801 is fixedly mounted on one end of the knob 8. A clamping block 802 is welded on one end of the rotating rod 801. A control block 803 is abutted against the outer wall of the clamping block 802. A movable rod 804 is movably connected to the bottom end of the control block 803. Specifically, the control block 803 is rotatably connected to the outer wall of the movable rod 804 through a pin shaft. A tension spring 805 is fixedly connected to one end of the movable rod 804, and a square tongue 806 is fixedly connected to the other end thereof. Specifically, (please refer to Figure 4 ) The tension spring 805 is welded to the right end of the movable rod 804, and the square tongue 806 is welded to the left end of the movable rod 804.

[0056] Specifically, the control block 803 is fixedly mounted on the upper surface of the movable rod 804 by rotating the connecting piece 807 at its bottom end. The movable rod 804 is slidably mounted inside the fixed box 7, and one end of the tension spring 805 is fixedly connected to the inner wall of the fixed box 7.

[0057] Reference Figure 1-2 A control panel 9 is fixedly installed inside the front panel 1, and the control panel 9 is connected to the driving motor 603 through a control line. A fingerprint collection window 10 is fixedly installed on the outer surface of the outer handle 3. The front panel 1 and the rear panel 2 are fixedly connected by a connecting bolt 11;

[0058] Specifically, a battery 12 for providing power for the entire device is placed inside the rear panel 2 , and a rear cover 13 for protecting the battery 12 is snapped onto the outer surface.

[0059] The implementation principle of Example 2 is as follows: by pressing down the outer handle 3, the connecting square shaft 5 drives the rotating block 503 to rotate inside the moving frame 501, and the moving frame 501 is pulled to move in the direction of the pushing plate 6, and the connecting protruding block 505 drives the connecting frame 504 to control the locking tongue 502 to shrink inside the fixed tube 506, thereby contacting the connection between the device and the door frame to achieve the door opening effect. When the locking tongue 502 protrudes from the outside of the device, when the door and the door frame are merged, the squeezing effect of the two is used to push the locking tongue 502 to the reset spring 507. Under the action of , it can quickly retract and pop out, effectively assisting the device to lock the door and reducing the wear between the lock tongue 502 and the door frame. After closing the door, turn the knob 8 to drive the rotating rod 801 to connect the card block 802 to approach the control block 803, and then push the movable rod 804 to drive the square tongue 806 to extend out of the device to perform the anti-locking operation. When the anti-lock needs to be released, rotate the rotating rod 801 in the opposite direction to make the card block 802 away from the control block 803, so that the tension spring 805 pulls the movable rod 804 to drive the square tongue 806 to reset to release the anti-lock.

[0060] Working principle:

[0061] The control line is connected through the control panel 9 and the fingerprint collection window 10 to control the operation of the driving motor 603, so that the output end of the driving motor 603 is connected to the threaded rod 604 to drive the movable part 605 to control the plug block 607 to separate from the square shaft 5, and the restriction on the square shaft 5 is released. Then, the outer handle 3 is pressed down to connect the square shaft 5 to drive the rotating block 503 to pull the moving frame 501, so that the protruding block 505 drives the connecting frame 504 to control the lock tongue 502 to retract, and the unlocking operation is completed. At the same time, the moving frame 501 will be initially limited, and the square shaft 5 will also be limited and cannot rotate, which is conducive to the device. To perform the final lock, the knob 8 is finally turned to drive the rotating rod 801 to connect the card block 802 to the control block 803, and then the movable rod 804 is pushed to drive the square tongue 806 to extend out of the device to perform the reverse locking operation, thereby further ensuring the safety of the device. In addition, after the door is opened, the lock tongue 502 protrudes from the outside of the device. When the door and the door frame are merged, the squeezing effect of the two is utilized to push the lock tongue 502 to quickly retract and pop out under the action of the reset spring 507, thereby effectively assisting the device to perform the door locking operation and reducing the wear between the lock tongue 502 and the door frame.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
