If the password is correct, the door lock can be opened through the Internet.

[0034] Reference Figure 1-3 The two buckle assemblies include four clamping blocks 2, which are respectively arranged inside the two door frames 1. Two door panels 3 are rotatably connected to the opposite sides of the four clamping blocks 2. Two installation boxes 4 are fixedly connected inside the door frame 1. The insides of the two installation boxes 4 are slidably connected with clamping rods 5, which are plugged and engaged with the clamping blocks 2. The opposite sides of the two clamping rods 5 are fixedly connected with support rods 6, and the opposite sides of the two support rods 6 are rotatably connected with push rods 7. The adjacent sides of the two push rods 7 are rotatably connected with sliding rods 8, and the outside of the sliding rods 8 is slidably connected with a rod sleeve 9. The outsides of the two clamping rods 5 are fixedly connected with limit plates 10, and the opposite sides of the two limit plates 10 are fixedly connected with springs 11.

[0035] Specifically, the card block 2 plays a role in determining the position of the door panel 3, the door panel 3 plays a role in isolating the space, the installation box 4 plays a role in providing an installation space and being able to limit the moving trajectory of the card rod 5, the card rod 5 plays a role in engaging with the card block 2 to fix the card block 2, the support rod 6 plays a role in connecting the card rod 5 and the push rod 7, the push rod 7 plays a role in connecting the support rod 6 and the sliding rod 8, the sliding rod 8 plays a role in pushing the push rod 7 to deviate, the rod sleeve 9 plays a role in limiting the moving trajectory of the sliding rod 8, the limiting plate 10 plays a role in connecting the card rod 5 and the spring 11, and the spring 11 plays a role in preventing the card rod 5 from escaping from the inside of the card block 2.

[0036] Reference Figure 2-4 The side of the spring 11 away from the limiting plate 10 is fixedly connected to the inside of the installation box 4, the clamping rod 5 passes through the installation box 4, the sliding rod 8 is slidably connected to the inside of the door frame 1, and the rod sleeve 9 is fixedly connected to the inside of the door frame 1.

[0037] Specifically, the side of the spring 11 away from the limit plate 10 is fixedly connected to the inside of the installation box 4 to make the thrust of the spring 11 on the limit plate 10 more stable. The clamping rod 5 passes through the installation box 4 to facilitate the connection between the clamping rod 5 and the support rod 6, and to facilitate the clamping of the clamping rod 5 and the clamping block 2. The outer sliding connection of the sliding rod 8 is convenient for driving the push rod 7 to move, and the rod sleeve 9 is fixedly connected to the inside of the door frame 1 to fix the position of the rod sleeve 9.

[0038] Reference Figure 1 and Figure 5 The output end of the motor 1202 passes through the bottom of the support frame 1201, the threaded rod 1203 is rotatably connected to the inside of the support frame 1201, a threaded groove is opened inside the slider 1205, a sliding groove is opened inside the slider 1205, and the display screen 1207 passes through the front side of the door frame 1.

[0039] Specifically, the output end of the motor 1202 passes through the bottom of the support frame 1201 to facilitate the fixed connection with the threaded rod 1203. The threaded rod 1203 is rotatably connected to the inside of the support frame 1201 to fix the position of the threaded rod 1203. The threaded groove is threadedly connected to the threaded rod 1203. The slide groove facilitates the sliding of the slider 1205 outside the limit rod 1204. The display screen 1207 passes through the front side of the door frame 1 to facilitate the connection between the display screen 1207 and the slider 1205.

[0040] Working principle: when the height of the display screen 1207 needs to be adjusted, it is only necessary to start the motor 1202, and the motor 1202 drives the slider 1205 to move up and down through the threaded rod 1203, and then drives the display screen 1207 to move up and down through the support block 1206 to adjust the height, thereby realizing the ability to adjust the height of the display screen 1207, which is convenient for people of different heights, as well as vulnerable groups such as the disabled, to unlock the door through face recognition and password operations through the display screen 1207, thereby improving practicality. When the door panel 3 needs to be disassembled and replaced, it is only necessary to push the sliding rod 8 forward, and the sliding rod 8 drives the push rod 7 to deviate and drive the two support rods 6 to move away from each other, thereby driving the two card rods 5 to move away from each other so that they cannot be engaged with the card block 2, and then move outward. The card block 2 can be removed by pressing the card block 2. When installing the door panel 3, you only need to push the sliding rod 8 forward. The sliding rod 8 drives the push rod 7 to deviate and drives the two support rods 6 to move backwards, thereby driving the two card rods 5 to move backwards to provide installation space for the card block 2. At the same time, the two card rods 5 respectively drive the two limit plates 10 to squeeze the spring 11, and then the card block 2 is pushed into the door frame 1. At the same time, the sliding rod 8 is released, and the spring 11 resets and extends through the limit plate 10 to drive the card rod 5 to be stuck in the inside of the card block 2. At the same time, the card rod 5 drives the push rod 7 to deviate through the support rod 6, thereby driving the sliding rod 8 to move backward and reset, so that the door panel 3 can be easily disassembled and installed. After the door panel 3 is damaged, the damaged door panel 3 can be removed and replaced with a new one, which saves time and effort and reduces maintenance costs.

[0041] 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.
