[0003] An existing intelligent anti-theft door access control device (announcement number: CN115482617A) has at least the following drawbacks: the device achieves intelligent opening and closing of the anti-theft door body by moving the threaded sleeve out or in through the limiting hole, but it can only fix the anti-theft door body vertically by the threaded sleeve and the limiting hole, resulting in insufficient security performance, unsatisfactory anti-theft effect on residences, and inconvenient operation for users, with low flexibility of use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent access control and anti-theft device based on a wireless network.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A smart access control and anti-theft device based on a wireless network includes a door panel body and a door frame. An inner groove is formed on the inner side of the door panel body, and a slide rail is fixedly installed inside the groove. A fixed frame is fixedly installed on the slide rail, and an electric push rod is installed on the fixed frame via fasteners. A U-shaped plate is fixedly installed at the end of the electric push rod away from the fixed frame, and a movable rod is fixedly installed on the U-shaped plate. A transmission gear is disposed inside the U-shaped plate, and the transmission gear is movably connected to the movable rod. A toothed plate is disposed on one side of the transmission gear, and the transmission gear meshes with the toothed plate. A limit block is fixedly installed at one end of the toothed plate, and a positioning block is fixedly installed at the end of the toothed plate away from it. A door lock panel is fixedly installed on the outer side of the door panel body, and a cover plate is installed on the door lock panel.

[0007] As a further embodiment of this utility model, a buffer spring is fixedly provided between the limiting block and the fixed frame, a second toothed plate is provided on the side of the transmission gear away from the first toothed plate, the transmission gear is meshed with the second toothed plate, the bottom of the second toothed plate is fixedly connected to the inner wall of the inner groove, and a pressure sensor is fixedly installed inside the door lock panel.

[0008] As a further embodiment of this utility model, a password button is fixedly provided on the door lock panel, a fingerprint recognition groove is provided on the door lock panel, an installation frame is fixedly installed on one side of the door lock panel, a connecting side plate is provided on one side of the installation frame, and the connecting side plate is connected to the installation frame by expansion bolts.

[0009] As a further embodiment of this utility model, a baffle plate is provided between the mounting frame and the connecting side plate, a slider is fixedly provided on the baffle plate, the slider is slidably connected to the connecting side plate, and a door handle is provided on one side of the door lock panel, the door handle is installed on the outside of the door panel body by fasteners.

[0010] As a further embodiment of this utility model, the positioning block is embedded inside the door frame and extends through one side of the door panel body, and the bottom of the toothed plate is slidably connected to the slide rail.

[0011] As a further embodiment of this utility model, an alarm is fixedly installed on the door frame, the door panel body is connected to the door frame via a hinge, and the shielding plates are symmetrically distributed on the door lock panel.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the user verifies their fingerprint and the fingerprint is correctly identified, the control system controls the electric push rod. Since the transmission gear meshes with the second toothed plate, when the electric push rod moves the transmission gear by extending and retracting, the second toothed plate drives the transmission gear to rotate. The transmission gear meshes with the first toothed plate, causing the first toothed plate to slide on the slide rail. This causes the first toothed plate to push the positioning block into the interior of the door frame, closing the door panel. During the movement of the first toothed plate, the movement of the limiting block compresses and deforms the buffer spring, providing a buffering effect. At the same time, the fixed frame and the limiting block limit the first toothed plate, preventing it from disengaging from the slide rail and ensuring the stability of the movement.

[0014] 2. By twisting multiple expansion bolts, install the two sets of connecting side plates on the mounting frame. When the user needs to enter a password, pull the cover plate to make the slider slide outward along the groove on the connecting side plate, and move the cover plate out. The two sets of cover plates cover the side of the door lock panel, making it easier for the user to enter the password to open the door, preventing strangers from seeing the password, and enhancing security.

[0024] Reference Figures 1-5 A smart access control and anti-theft device based on a wireless network includes a door panel body 1 and a door frame 2. The inner side of the door panel body 1 has an inner groove 102. A slide rail 804 is fixedly installed inside the inner groove 102. A fixed frame 6 is fixedly installed on the slide rail 804. An electric push rod 8 is installed on the fixed frame 6 by fasteners. A U-shaped plate 7 is fixedly installed at the end of the electric push rod 8 away from the fixed frame 6. A movable rod 106 is fixedly installed on the U-shaped plate 7. A transmission gear 105 is provided inside the U-shaped plate 7. The transmission gear 105 is movably connected to the movable rod 106. A toothed plate 104 is provided on one side of the transmission gear 105. The transmission gear 105 is meshed with the toothed plate 104. A limit block 803 is fixedly installed at one end of the toothed plate 104. A positioning block 103 is fixedly installed at the end of the toothed plate 104 away from the toothed plate 104. A door lock panel 3 is fixedly installed on the outer side of the door panel body 1. A cover plate 203 is installed on the door lock panel 3.

[0025] In use, when the user verifies their fingerprint via 302, after successful fingerprint recognition, the control system controls the electric push rod 8. Since the transmission gear 105 meshes with the toothed plate 801, when the electric push rod 8 moves the transmission gear 105 by extending and retracting, the toothed plate 801 drives the transmission gear 105 to rotate, and the transmission gear 105 meshes with the toothed plate 104. Thus, the transmission gear 105 drives the toothed plate 104 to slide on the slide rail 804, causing the toothed plate 104 to push the positioning block 103 into the interior of the door frame 2, closing the door panel body 1. During the movement of the toothed plate 104, the movement of the limiting block 803 compresses and deforms the buffer spring 802, providing a buffering effect. At the same time, the fixed frame 6 and the limiting block 803 limit the toothed plate 104, preventing the toothed plate 104 from disengaging from the slide rail 804 and ensuring the stability of the movement.

[0026] In this embodiment, a buffer spring 802 is fixedly provided between the limiting block 803 and the fixed frame 6. A toothed plate 801 is provided on the side of the transmission gear 105 away from the toothed plate 104. The transmission gear 105 is meshed with the toothed plate 801. The bottom of the toothed plate 801 is fixedly connected to the inner wall of the inner groove 102. A pressure sensor 5 is fixedly installed inside the door lock panel 3.

[0027] In use, by twisting multiple expansion bolts 201, the two sets of connecting side plates 202 are installed on the mounting frame 4. When the user needs to enter a password, the cover plate 203 is pulled, so that the slider 303 slides outward along the groove on the connecting side plate 202, and the cover plate 203 is moved out. The two sets of cover plates 203 cover the side of the door lock panel 3, making it easier for the user to enter the password to open the door, preventing strangers from seeing the password, and enhancing security.

[0028] In this embodiment, a password button 301 is fixedly installed on the door lock panel 3, a fingerprint recognition slot 302 is opened on the door lock panel 3, an installation frame 4 is fixedly installed on one side of the door lock panel 3, a connecting side plate 202 is provided on one side of the installation frame 4, and the connecting side plate 202 is connected to the installation frame 4 by expansion bolts 201.

[0029] In use, the transmission gear 105 is a spur gear, and the gear plate 801 and gear plate 104 are spur racks. Therefore, the transmission gear 105 meshes with the two sets of gear plates and closes the door panel body 1 by pushing the positioning block 103 into the inner wall of the connecting door frame 2.

[0030] In this embodiment, a baffle plate 203 is provided between the mounting frame 4 and the connecting side plate 202. A slider 303 is fixedly provided on the baffle plate 203. The slider 303 is slidably connected to the connecting side plate 202. A door handle 101 is provided on one side of the door lock panel 3. The door handle 101 is installed on the outside of the door panel body 1 by fasteners.

[0031] In use, by pulling the cover plate 203, the slider 303 is driven to slide outward along the groove on the connecting side plate 202, thereby moving the cover plate 203 out. The two sets of cover plates 203 cover both sides of the door lock panel 3, making it easier for the user to enter the password to open the door.

[0032] In this embodiment, the positioning block 103 is embedded inside the connecting door frame 2 and passes through one side of the connecting door panel body 1, and the bottom of the toothed plate 104 is slidably connected to the slide rail 804.

[0033] During use, as the toothed plate 104 moves, it simultaneously drives the limiting block 803 to move. The limiting block 803 and the fixed frame 6 compress the buffer spring 802. By compressing the buffer spring 802, the buffer spring 802 is deformed, absorbing the energy of vibration, maintaining stability during movement, and facilitating the buffer reset of 104.

[0034] In this embodiment, an alarm 805 is fixedly installed on the door frame 2, the door panel body 1 is connected to the door frame 2 by a hinge, and the shielding plate 203 is symmetrically distributed on the door lock panel 3.

[0035] When in use, if the door lock panel 3 is damaged by external force, the pressure sensor 5 sends a signal to the control system, thereby triggering the alarm 805, which then sounds an alarm to enhance the anti-theft function.

[0036] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the user performs fingerprint verification through 302, after the fingerprint recognition is correct, the electric push rod 8 is controlled by the control system. Since the transmission gear 105 meshes with the toothed plate 801, when the electric push rod 8 pushes the transmission gear 105 to move by extension and retraction, the toothed plate 801 drives the transmission gear 105 to rotate, and the transmission gear 105 meshes with the toothed plate 104. Thus, the transmission gear 105 drives the toothed plate 104 to slide on the slide rail 804, so that the toothed plate 104 pushes the positioning block 103 to embed into the interior of the door frame 2, closing the door panel body 1. During the movement of the toothed plate 104... In the middle, the movement of the limiting block 803 compresses and deforms the buffer spring 802, providing a buffering effect. At the same time, the fixed frame 6 and the limiting block 803 limit the toothed plate 104, preventing the toothed plate 104 from disengaging from the slide rail 804 and ensuring the stability of movement. By twisting multiple expansion bolts 201, the two sets of connecting side plates 202 are installed on the mounting frame 4. When the user needs to enter a password, the cover plate 203 is pulled, causing the slider 303 to slide outward along the groove on the connecting side plate 202, moving the cover plate 203 out. The two sets of cover plates 203 cover the side of the door lock panel 3, making it easier for the user to enter the password to open the door, preventing strangers from seeing the password, and enhancing security.
