Description

Technical Field

[0001] The utility model relates to the technical field of alarm devices, in particular to an illegal intrusion alarm device. Background Art

[0002] An alarm device is an electronic product that uses sound, light, air pressure, etc. to remind or warn us that we should take certain actions in order to prevent or prevent the consequences of an event.

[0003] For example, the announcement number is: CN220290282U (named as an intrusion alarm device), comprising: a door body, the inner wall of the door body is provided with a cavity, the inner wall of the cavity is installed with a locking structure, and also includes an anti-pry alarm structure installed in the cavity, the anti-pry alarm structure includes: a protective rod, the front end of the protective rod is fixedly connected to a connecting frame, the front bottom end of the connecting frame is fixedly connected to a sensor; and a U-shaped frame, the inner wall of the U-shaped frame is slidably connected to a limiting rod, the outer wall of the limiting rod is slidably connected to a spring, the top end of the spring is fixedly connected to the outer wall of the limiting rod, and the bottom end of the spring is fixedly connected to the bottom end of the inner wall of the U-shaped frame. The locking structure comprises: a moving frame, a lock head is fixedly installed on the right end of the moving frame, both ends of the inner wall of the cavity are provided with sliding grooves, the inner wall of the sliding groove is slidably connected with a slider, and the end of the slider away from the sliding groove is fixedly connected to the outer wall of the moving frame. When the door lock is pried, the password lock body is damaged, which will drive the guard plate to fall off. The influence of the spring rebound force pushes the limiting rod to insert into the horizontal groove opened on the baffle plate, and at the same time presses against the bottom end of the sensor. The sensor receives the pressing thrust and transmits the signal to the PLC control circuit board. The PLC control circuit board controls the buzzer alarm to sound an alarm, prompting people in the room to be in danger, thereby improving safety quality.

[0004] The above-mentioned intrusion alarm device can alarm when the lock is pried through the linkage mechanism, but illegal intrusion can also be carried out by cutting the door body without prying the lock. Only setting the prying alarm cannot meet the security needs. For this reason, we provide an illegal intrusion alarm device. Utility Model Content

[0005] The utility model aims to provide an illegal intrusion alarm device to solve the problem that the existing intrusion alarm device proposed in the above background technology can alarm when the lock is pried open by setting a linkage mechanism, but illegal intrusion can be carried out without prying the lock and cutting the door body, resulting in that the only lock-picking alarm cannot meet the security needs.

[0006] To achieve the above object, the utility model provides the following technical solutions: an illegal intrusion alarm device, comprising a door frame base, a stainless steel door frame is arranged at the upper end of the door frame base, the stainless steel door frame and the door frame base are an integrated structure, and a safety door is arranged inside the stainless steel door frame;

[0007] Also includes:

[0008] A load-bearing groove is arranged on the inner side of the stainless steel door frame, the load-bearing groove and the door frame base are an integrated structure, and a gravity sensor is arranged inside the load-bearing groove, and a load-bearing platform is abutted against the top sensing end of the gravity sensor;

[0009] An electromagnet is arranged on the bottom inner wall of the stainless steel door frame; and an alarm is fixedly mounted on the inner outer wall of the stainless steel door frame by screws;

[0010] A ceramic tile block is arranged on the outer side of the stainless steel door frame, the ceramic tile block is connected to the upper end of the door frame base, and a switch slot is arranged below one ceramic tile block, the switch slot and the door frame base are an integrated structure, and a power switch is arranged inside the switch slot.

[0011] Preferably, a closed groove is provided on the inner wall of one side of the stainless steel door frame, and a plug-in end block is provided on the outer wall of one side of the safety door. The plug-in end block and the safety door are an integrated structure, and the safety door is correspondingly connected to the closed groove on the inner wall of the stainless steel door frame through the plug-in end block.

[0012] Preferably, an embedding groove is provided at the connection position between the electromagnet and the stainless steel door frame, and the embedding groove and the stainless steel door frame are an integral structure.

[0013] Preferably, a power box is provided on the front end surface of the door frame base, the output end of the power box is electrically connected to the input end of the power switch, and the output end of the power switch is electrically connected to the input end of the electromagnet and the alarm.

[0014] Preferably, a hinge is provided at the connection position between the safety door and the stainless steel door frame, and the safety door is movably connected to the stainless steel door frame through the hinge.

[0015] Preferably, the output end of the gravity sensor is electrically connected to the input end of the alarm.

[0016] Preferably, the size of the load-bearing platform is equal to the caliber of the load-bearing groove.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. When the user chooses to pry the lock for intrusion, the safety door is fixedly locked by electromagnet adsorption, so that non-staff cannot pry the lock, thereby preventing illegal intrusion. When the user chooses to cut the safety door for intrusion, even if the cut hole passes through the stainless steel door frame, the gravity sensor will sense the gravity and trigger the alarm because it contacts the load-bearing platform, thereby achieving the purpose of alarming the illegal intrusion. The utility model overcomes the problem that the existing intrusion alarm device alarms when the lock is pried through the linkage mechanism, but illegal intrusion can be carried out by cutting the door body without prying the lock, resulting in the problem that the prying alarm alone cannot meet the security needs.

[0019] 2. When the staff needs to enter, they lift one of the tiles, then press the power switch to disconnect the power box from the electromagnet and the alarm, causing the electromagnet to lose its magnetic force and the alarm to fail to sound. The staff can then open the safety door and enter the workroom. Non-staff members do not know that the power switch is hidden under the tiles, making it easier to distinguish between normal entry and illegal intrusion. BRIEF DESCRIPTION OF THE DRAWINGS
