[0029] Reference Figure 1-5The utility model provides an embodiment: a security smart door lock, comprising a protective shell 1, a control panel 2 is fixedly connected to the upper front end of the protective shell 1, and the control panel 2 is used to form a control panel of a password lock, an outer handle 4 is movably connected to the middle of the front end of the protective shell 1, and a halo 3 is sleeved at the connection between the outer handle 4 and the protective shell 1, a fingerprint screen 5 is fixedly connected to one side of the front end of the outer handle 4, and the fingerprint screen 5 is installed with the outer handle 4 to form a fingerprint lock, and the halo 3 is used to prompt the use of the fingerprint lock, a lock body 6 is fixedly connected to the middle of the rear end of the protective shell 1, and the door lock structure is installed by using the lock body 6, and the rear end of the lock body 6 is detachably connected to the inner shell 7, and the middle of the rear end of the inner shell 7 is fixedly connected to the inner handle 8, and the inner shell 7 is used to An inner handle 8 for opening the door is installed on the inside of the door, and a lock inner box 9 is fixedly connected to the inside of the lock body 6 for installing the door lock structure. A lock head 10 is inserted on one side of the lock inner box 9, and a transmission plate 11 is fixedly connected to one side of the lock head 10, and a transmission rod 12 is fixedly connected to one side of the transmission plate 11, and a lock ring 13 is fixedly connected to the lower end of the transmission rod 12. The rotation of the lock ring 13 causes the transmission rod 12 to pull the transmission plate 11 to control the telescopic stroke of the lock head 10. A numerical control board 14 is detachably connected to the upper end of the inner part of the protective shell 1, which receives instructions from the control board 2 through the numerical control board 14 and responds to the door lock. An extension rod 15 is inserted on one side of the rear end of the outer handle 4, and the extension rod 15 is used to transmit the movement of the handle to the lock ring 13.
[0030] Specifically, the numerical control board 14 is installed inside the protective shell 1 , and the numerical control board 14 is connected to the control board 2 through the protective shell 1 . The control board 2 sends instructions to the numerical control board 14 to activate the password lock.
[0031] Specifically, the lock body 6 is in the shape of a cuboid, and the lock inner box 9 is in the shape of a cuboid. The size of the lock body 6 is larger than that of the lock inner box 9, so that the lock inner box 9 can be accommodated inside the lock body 6 and provide protection at the same time.
[0032] Specifically, there are two lock heads 10, which are inserted into the lock inner box 9. The lock head 10 is connected to the lock ring 13 through a transmission plate 11 fixedly connected on the left side, a transmission rod 12, and a transmission ring 13. The movement of the transmission plate 11 and the transmission rod 12 is used to control the extension and retraction of the lock head 10.
[0033] Specifically, the protective shell 1 is in the shape of a cuboid, and the inner shell 7 is in the shape of a cuboid. The protective shell 1 and the inner shell 7 have the same size and are symmetrically installed through the lock body 6 in the middle. The symmetrical installation enhances the stability of the door lock structure.
[0034] Specifically, the extension rod 15 is plugged into the rear end of the fingerprint screen 5 through the outer handle 4, and the other end of the extension rod 15 is plugged into the inner handle 8 through the inside of the lock body 6. The extension rod 15 is used to connect the outer handle 4 and the inner handle 8, so that both handles have the function of unlocking.
[0035] Specifically, the shape of the halo 3 is ring-shaped, and the halo 3 is connected to the connection between the outer handle 4 and the protective shell 1. The size of the halo 3 is larger than the plane size of the connection between the outer handle 4 and the protective shell 1. The halo 3 is used to prompt the use of fingerprint unlocking, and is set to two different lights. One light will be prompted when the unlocking is successful, and another light will be prompted when the unlocking fails, telling the user to change the fingerprint angle to unlock.
[0036] Working principle: When the user wants to use fingerprint to unlock the security smart door lock, the user holds the outer handle 4 with his hand and presses the thumb on the fingerprint screen 5. At this time, the CNC board 14 receives the command and moves the transmission rod 12. At this time, the lock ring 13 is forced to rotate, bringing the transmission rod 12 to the rear, and the transmission plate 11 connected to the transmission rod 12 also moves backward, pulling the lock head 10 backward to shrink and open the door lock. At this time, the halo 3 will emit a set light to prompt that the door can be opened. If the finger used is not the finger used to enter the fingerprint, the halo 3 will emit another light to prompt the fingerprint error; if the password is to be used to unlock the security smart door lock, the user enters the set password on the control panel 2 with his finger, and then the button on the control panel 2 will The signal is transmitted to the CNC board 14, and the CNC board 14 receives the command to move the transmission rod 12. At this time, the lock ring 13 is forced to rotate and bring the transmission rod 12 to the rear. The transmission plate 11 connected to the transmission rod 12 also moves backward, pulling the lock head 10 backward to shrink and open the door lock. Then the user grabs the outer handle 4 to open the door; if the security smart door lock needs to replace the battery or overhaul, the maintenance personnel need to use tools to remove the inner shell 7 on the back of the door, and then take out the CNC board 14 for maintenance, or replace the battery, or repair the door lock structure in the lock inner box 9. When the maintenance is completed, the inner shell 7 is reinstalled. During installation, pay attention to align the extension rod 15 with the inner handle 8 to prevent damage caused by installation errors, and then complete the maintenance work.
[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
