[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-9 The utility model is a concealed anti-theft and anti-prying device, comprising a door frame 1, a door panel 2 is hinged inside the door frame 1, an alarm 3, a controller 4 and an electromagnetic lock are installed on one side of the door panel 2, a retractable anti-prying plate 7 is arranged on the side walls around the door panel 2, the anti-prying plate 7 is arranged along the width and height directions of the door panel 2, an anti-prying plate groove 8 corresponding to the anti-prying plate 7 is arranged on the inner side wall of the door frame 1, and a vibration sensor 20 is also installed on one side of the door panel 2.

[0029] The electromagnetic lock and the vibration sensor 20 are fixedly mounted on the side wall inside the door panel 2, and are concealed to prevent damage from outside the door panel 2 or inside the door gap.

[0030] When the door panel 2 is closed, the electromagnetic lock and the anti-pry plate 7 are locked at the same time. The anti-pry plate 7 prevents someone from inserting tools through the door gap from the outside. In the prior art, the gap between the door panel and the door frame is narrow. When someone wants to destroy the anti-pry plate 7 from the outside, he must knock a crowbar into the door gap. The knocking is detected by the vibration sensor 20. The vibration sensor 20, the controller 4 and the alarm 3 are electrically connected. After the vibration sensor 20 detects the knocking, it sends a signal to the controller 4. The controller 4 activates the alarm 3 to alarm, thereby achieving the anti-theft and anti-pry effect.

[0031] A through slot 13 is provided on the side wall of the door panel 2, and the anti-pry plate 7 is movably inserted into the through slot 13. An inner frame 11 is provided inside the door panel 2, and the anti-pry plate 7 is located between the side wall of the door panel 2 and the inner frame 11. A sliding column 14 is provided at one end of the anti-pry plate 7 close to the inner frame 11, and the anti-pry plate 7 is slidably installed on the inner frame 11 through the sliding column 14.

[0032] The inner frame 11 is welded to the door panel 2, which can not only fix the inner frame 11, but also enhance the structural strength of the door panel 2 near the edge, thereby further improving the anti-pry effect.

[0033] The inner frame 11 is a rectangular frame structure, and the sliding column 14 is slidably installed in the inner frame 11. The sliding column 14 has a guiding function. The anti-pry plate 7 is slidably connected to the inner frame 11 through the sliding column 14, specifically sliding to the upper and lower sides and left and right sides of the door panel 2, extending when locking the door and retracting when opening the door.

[0034] A driving mechanism is arranged in the middle of the door panel 2. The electromagnetic lock comprises a lock body 5 installed on the door panel 2 and a lock box 6 installed on the door frame 1. A lock tongue 9 and a proximity switch 10 are arranged on the end surface of the lock body 5 close to the lock box 6. The proximity switch 10 is electrically connected to the driving mechanism.

[0035] When locking the door, the lock body 5 is close to the lock box 6 and aligned with the lock box 6. After the alignment, the lock tongue 9 clamps the lock box 6.

[0036] The working surface of the proximity switch 10 faces the lock box 6. After the working surface of the proximity switch 10 blocks the lock box 6, a signal is sent to the controller 4. The controller 4 controls the driving mechanism to start, and the driving mechanism drives the anti-pry plate 7 to extend into the anti-pry plate slot 8. Compared with the prior art, the anti-pry plate 7 is locked synchronously with the electromagnetic lock, and there is no need for secondary locking. The operation is simpler and the situation of forgetting to activate the anti-pry plate 7 can be prevented.

[0037] When opening the door, the user controls the electromagnetic lock and the driving mechanism through the controller 4, and the lock tongue 9 and the anti-pry plate 7 are retracted synchronously.

[0038] The driving mechanism includes a rotatable turntable 15 , the eccentric position of the turntable 15 is hinged to one end of a connecting rod 18 , the other end of the connecting rod 18 is hinged to a slide bar 12 , and the other end of the slide bar 12 is connected to an end of the inner frame 11 away from the anti-pry plate 7 .

[0039] When the turntable 15 rotates, the connecting rod 18 is driven to approach or move away from the turntable 15, thereby driving the sliding rod 12 to slide toward or away from the turntable 15, and further driving the anti-pry plate 7 to approach or move away from the turntable 15. When the anti-pry plate 7 approaches the turntable 15, the anti-pry plate 7 retracts, and when the anti-pry plate 7 moves away from the turntable 15, the anti-pry plate 7 extends.

[0040] The slide bar 12 here passes through the inner frame 11 and is movably arranged in the inner frame 11 .

[0041] The turntable 15 includes a disc 17 and a shaft 19 . The disc 17 is rotatably connected to the door panel 2 via the shaft 19 . Both ends of the shaft 19 are rotatably connected to the front side wall and the rear side surface of the door panel 2 . The disc 17 and the shaft 19 are fixedly connected.

[0042] An electric cylinder 16 is provided on one side of the rotating shaft 19. The two ends of the electric cylinder 16 are respectively hinged to the door panel 2 and the disc 17. When the electric cylinder 16 is extended or retracted, it drives the disc 17 to rotate forward or reversely by a certain angle.

[0043] The slide bar 12 is provided with a guide tube 21 . A plurality of guide tubes 21 are evenly arranged along the extension and retraction direction of the slide bar 12 . The slide bar 12 is installed inside the door panel 2 through the guide tubes 21 .

[0044] The slide bar 12 is slidably inserted into the guide tube 21 , and the guide tube 21 is fixedly connected to the front and rear side walls of the door panel 2 , so that the slide bar 12 can slide more smoothly and prevent the slide bar 12 from being skewed or bent.

[0045] Working principle: when the door panel 2 is closed, the lock tongue 9 is inserted into the lock box 6, and the proximity switch 10 sends a signal to the controller 4. The controller 4 starts the electric cylinder 16 to drive the disc 17 to rotate a certain angle. The disc 17 drives the slide bar 12 through the connecting rod 18 to drive the anti-pry plate 7 to extend, and the anti-pry plate 7 extends into the anti-pry plate slot 8.

[0046] When someone outside the door wants to use a tool to penetrate the door crack, the anti-pry plate 7 blocks the tool from entering. When a tool is used to knock and forcibly destroy the anti-pry plate 7 or the door panel 2, the vibration sensor 20 detects the vibration and sends a signal to the controller 4. The controller 4 activates the alarm 3 to sound an alarm, deterring outsiders and reminding the user at the same time.
