The camera 16 can be connected to the user's mobile phone, and after the camera 16 takes a snapshot, the photo can be transmitted to the user's mobile phone.

[0031] The alarm component may also be connected to a buzzer, which may sound when the alarm component is triggered, thereby alerting users indoors and deterring secret thieves.

[0032] The alarm assembly includes a housing 11, a driving motor 12 and a lifting rack 13. The housing 11 is fixedly mounted on the inner side of the door body 1, that is, it is arranged inside the house. Figure 4As shown, the fixing seat of the driving motor 12 is fixed on the right side wall of the shell 11, and the left end of the driving motor 12 is provided with a driving shaft 21, and the driving shaft 21 is preferably a spline shaft. A clutch 22 is slidably provided on the driving shaft 21, that is, a spline hole is provided in the clutch 22. When the driving motor 12 is triggered, the driving shaft 21 can rotate to drive the clutch 22 to rotate. The driving motor 12 is electrically connected to the induction switch 5, that is, when any induction switch 5 is triggered, the driving motor 12 can be energized to rotate the driving shaft 21 to a certain angle.

[0033] A gear 14 is rotatably disposed on the left wall of the housing 11, and the gear 14 cooperates with the clutch 22. Specifically, Figure 5 As shown, the gear 14 is fixedly provided with a second tooth portion 25 on one side close to the clutch 22, and the clutch 22 is provided with a first tooth portion 24 that matches the second tooth portion 25. When the first tooth portion 24 is engaged with the second tooth portion 25, the clutch 22 can drive the gear 14 to rotate synchronously.

[0034] A first spring 23 is provided between the clutch 22 and the drive motor 12. The first spring 23 is sleeved on the drive shaft 21 and the two ends thereof are respectively pressed against the housing of the drive motor 12 and the clutch 22. The lifting rack 13 is provided on one side of the gear 14 and meshes with it. When the gear 14 is driven to rotate clockwise, the lifting rack 13 can slide vertically upward. Specifically, a guide rod 26 matching the lifting rack 13 is provided on the bottom wall of the shell 11. The guide rod 26 is preferably a hexagonal rod. A hexagonal hole vertically matching the hexagonal rod is provided in the lifting rack 13. When the lifting rack 13 is driven by the gear 14, it can slide vertically upward on the guide rod 26.

[0035] The lower end of the guide rod 26 is provided with a limiting plate 101 that cooperates with the lifting rack 13 to prevent the lifting rack 13 from being out of contact with the gear 14 when falling. The lower end of the lifting rack 13 is provided with a counterweight block 102. When the lifting rack 13 is out of contact with the gear 14, it can fall freely by its own weight due to the counterweight block 102 and be limited by the limiting plate 101.

[0036] A push rod 27 is provided at the upper end of the lifting rack 13, and an alarm switch 15 that cooperates with the push rod 27 is provided on the top wall of the shell 11. When the lifting rack 13 is gradually lifted upward, the alarm switch 15 can be triggered when the push rod 27 abuts against the alarm switch 15. The alarm switch 15 is connected to the camera 16 and / or the buzzer.

[0037] In order to reset the lifting rack 13 after normal lifting, the clutch 22 is provided with a fork plate 31 that can drive the clutch 22 to slide on the drive shaft 21. The clutch 22 is provided with a slot 32 that matches the fork plate 31. The fork plate 31 is clamped in the slot 32. When the fork plate 31 is driven, the clutch 22 can slide toward the side close to the drive motor 12, so that the first tooth portion 24 is disengaged from the second tooth portion 25. At this time, the gear 14 is in a free rotation state, and the lifting rack 13 can fall freely under the action of the counterweight block 102.

[0038] One side of the fork plate 31 is rotatably clamped in the clamping groove 32, and the other side is extended to the side of the driving motor 12 and fixed with a fork rod 34. One end of the fork rod 34 is fixedly connected to the fork plate 31, and the other end is connected to the lock cylinder 3 through a pull rope 33. A guide plate 35 matching the fork rod 34 is provided on the upper shell of the driving motor 12. The fork rod 34 slides through the guide plate 35. A pull rope plate 36 matching the pull rope 33 is fixed on the right side of the guide plate 35. One end of the pull rope 33 is connected to the fork rod 34, and the other end passes through the pull rope plate 36 and the door body 1 in sequence and then is connected to the lock cylinder 3. Figure 6 As shown, when the lock cylinder 3 slides to the right to unlock the door body 1, the pull rope 33 can be pulled to move the fork rod 34 to the position shown in FIG. Figure 4 The shift fork plate 31 further drives the clutch 22 to slide to the right and disengage from the gear 14, so that the gear 14 is in a free state, and finally the lifting rack 13 can fall freely.

[0039] A method for using a household anti-theft door with an alarm function as described above: during normal use, the user enters 4 digits on the password panel 4, and the induction switch 5 is triggered 4 times. At this time, the driving motor 12 drives the lifting rack 13 to slide upward. At this time, the top rod 27 on the lifting rack 13 has not slid to the alarm switch 15, so the alarm switch 15 is not triggered, that is, the alarm switch 15 will not be triggered during normal use; then the user turns the handle to unlock the lock cylinder 3, so that the lock cylinder 3 slides, and after the lock cylinder 3 slides, the pull rope 33 pulls the fork plate 31 and disengages the clutch 22 from the gear 14, so that the lifting rack 13 automatically slides down and resets under the action of the counterweight block 102;

[0040] When the password thief enters the password digits on the password panel 4 multiple times, the induction switch 5 is continuously triggered, so the driving motor 12 drives the lifting rack 13 to continue to rise. After the induction switch 5 is triggered a certain number of times, the top rod 27 triggers the alarm switch 15, so that the camera 16 can take a snapshot of the password thief and transmit the photo to the user's mobile phone. It can also trigger the buzzer to sound, deter the password thief and warn the indoor user. The condition for the alarm switch 15 to be triggered can be adjusted by adjusting the position of the alarm switch 15 in the shell 11.
