Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Refer to Figure 1-3 , the present utility model provides a confidential room alarm device, including:

[0030] Installation frame 1, the installation frame 1 is fixed on the wall, and the cross-sectional shape of the installation frame 1 is a "return" shaped structure;

[0031] Installation block 2, the alarm main body is fixed on the installation block 2, the installation block 2 is matched with the shape of the installation frame 1, and a groove 3 is opened on one side of the installation block 2 close to the installation frame 1;

[0032] Fixing mechanism, there are no less than two groups of fixing mechanisms arranged on the installation block 2, and the installation block 2 and the installation frame 1 are fixed through the fixing mechanism;

[0033] Disassembly alarm mechanism, the disassembly alarm mechanism includes a first backing plate 4, a second backing plate 7, a third backing plate 8, and a fourth backing plate 9 arranged in parallel. The first backing plate 4 is fixed on the inner wall of the groove 3, the second backing plate 7 abuts against the wall, a plurality of first connecting rods 10 are fixed between the third backing plate 8 and the first backing plate 4, a second connecting rod 11 is fixed between the second backing plate 7 and the fourth backing plate 9, the third backing plate 8 is slidably connected to the second connecting rod 11, the fourth backing plate 9 is slidably connected to the first connecting rod 10, first springs 12 are respectively fixed between the third backing plate 8 and the second backing plate 7, and between the fourth backing plate 9 and the first backing plate 4, touch heads 5 and touch switches 6 are respectively fixed on the opposite sides of the third backing plate 8 and the fourth backing plate 9, the touch heads 5 and the touch switches 6 are arranged correspondingly, and an audible and visual alarm 13 is installed on the alarm main body, and the audible and visual alarm 13 is connected to the touch switch 6;

[0034] Among them, the touch switch 6 and the audible and visual alarm 13 are both connected to the controller.

[0035] When the utility model is in use, the installation frame 1 with a "hui" - shaped structure is fixed on the wall. The alarm main body is fixed on the installation block 2. Since the installation block 2 matches the shape of the installation frame 1, the installation block 2 is embedded into the installation frame 1, and the installation block 2 and the installation frame 1 are fixed together by no less than two groups of fixing mechanisms, completing the installation of the entire alarm device. At this time, the first backing plate 4 in the disassembly alarm mechanism is fixed on the inner wall of the groove 3, the second backing plate 7 abuts against the wall, the third backing plate 8 and the fourth backing plate 9 are in relatively stable positions on the first connecting rod 10 and the second connecting rod 11 respectively, the touch head 5 and the touch switch 6 are not in contact, and the sound and light alarm 13 does not give an alarm. When someone attempts to illegally disassemble the installation block 2, the fixation between the installation block 2 and the installation frame 1 will be damaged, resulting in relative displacement between the installation block 2 and the installation frame 1. This displacement will cause the third backing plate 8 and the fourth backing plate 9 in the disassembly alarm mechanism to slide on the first connecting rod 10 and the second connecting rod 11, thereby compressing or stretching the first spring 12. As the displacement increases, the touch head 5 on the third backing plate 8 will contact the touch switch 6 on the fourth backing plate 9. After the touch switch 6 is triggered, it will send a signal to the controller. After receiving the signal, the controller controls the sound and light alarm 13 to give an alarm, reminding relevant personnel that an illegal disassembly behavior has occurred.

[0036] The first spring 12 maintains a constant compressed state.

[0037] The touch head 5 made of conductive rubber material has good elasticity and electrical conductivity, with a size of 5 mm in diameter and 10 mm in length.

[0038] Touch switch 6: A micro switch is selected, such as Omron SS - 5GL2 micro switch. This switch has the following characteristics:

[0039] Actuating force: The actuating force is 1.96 N, with high sensitivity.

[0040] Contact resistance: The contact resistance is less than 50 mΩ, ensuring good electrical connection.

[0041] Lifespan: The mechanical lifespan can reach more than 10 million times, and the electrical lifespan can reach more than 100,000 times, with high reliability.

[0042] Type: A high - decibel and high - brightness sound and light alarm 13 is selected, which can clearly give an alarm at a long distance and in a noisy environment.

[0043] Specific model: Such as Ailefu AL - 927B sound and light alarm 13, which has the following characteristics:

[0044] Sound pressure level: The sound pressure level can reach above 110 dB, ensuring that the alarm sound can be heard by people in the distance.

[0045] Flash frequency: The flash frequency is 1 Hz - 3 Hz, and the high - brightness LED lights flash to attract people's attention.

[0046] Operating voltage: DC12V-24V, compatible with common power supply systems.

[0047] Protection rating: IP65, providing a certain degree of dust and water resistance, suitable for various environments.

[0048] Programmable logic controllers (PLCs) are selected because they offer advantages such as flexible programming, high reliability, and strong anti-interference capabilities.

[0049] Specific models: such as Siemens S7-200 SMART series PLC.

[0050] Connect the output terminal of the touch switch 6 in the disassembled alarm mechanism to the input terminal of the PLC. When the touch switch 6 is triggered, a switching signal is sent to the PLC. Connect the switching output interface of the alarm body to another input terminal of the PLC. When the alarm body detects smoke or infrared anomalies, it will also send an alarm signal to the PLC. Connect the control terminal of the audible and visual alarm 13 to the output terminal of the PLC. The PLC controls the start and stop of the audible and visual alarm 13 according to the received input signal. Provide a stable DC24V power supply for the entire device. The AC220V mains power can be converted to DC24V through a switching power supply to power the electrical components such as the alarm body, controller, and audible and visual alarm 13.

[0051] The scheme is further optimized. The fixing mechanism includes a positioning component and a fixing component. The side wall of the mounting block 2 has a mounting groove 14. The positioning component is installed in the mounting groove 14. The side wall of the mounting frame 1 has a through hole. The through hole is arranged coaxially with the mounting groove 14. The top of the positioning component is limited and matched with the through hole. The fixing component is inserted into the through hole. The fixing component and the positioning component are detachably connected.

[0052] The solution is further optimized. The positioning component includes a positioning block 15, which is slidably connected in the mounting groove 14. The top surface of the positioning block 15 is set as an arc surface. A threaded groove is opened on the top surface of the positioning block 15. A second spring 16 is fixed between the bottom of the positioning block 15 and the mounting block 2. The diameter of the arc corresponding to the arc surface of the top surface of the positioning block 15 is larger than the diameter of the through hole.

[0053] The solution is further optimized so that the fixing component includes a fixing bolt 17, which is inserted into the through hole and one end of the fixing bolt 17 is threadedly connected to the positioning block 15.

[0054] When the mounting block 2 is inserted into the mounting frame 1, the positioning block 15 is initially positioned at a relatively low position within the mounting groove 14 due to the elastic action of the second spring 16 at the bottom. As the mounting block 2 is further inserted, the arc surface of the top surface of the positioning block 15 will contact the side wall of the mounting frame 1. Due to the guiding effect of the arc surface, the positioning block 15 will overcome the elastic force of the second spring 16 and slide upward within the mounting groove 14.

[0055] When the mounting block 2 reaches the appropriate position, the arc surface of the top surface of the positioning block 15 will align with the through hole on the side wall of the mounting frame 1. At this time, the positioning block 15 will partially pop out of the mounting groove 14 under the action of the second spring 16 and enter the through hole. The diameter of the arc corresponding to the top surface of the positioning block 15 is larger than the diameter of the through hole, which can realize the limiting fit between the positioning block 15 and the through hole, and initially fix the positional relationship between the mounting block 2 and the mounting frame 1.

[0056] Insert the fixing bolt 17 into the through hole from the outside of the mounting frame 1, and thread it into the threaded groove on the top surface of the positioning block 15. As the fixing bolt 17 is tightened, the positioning block 15 is further pressed between the mounting groove 14 and the through hole, which enhances the fixing strength between the mounting block 2 and the mounting frame 1 and prevents the mounting block 2 from loosening.

[0057] The design is further optimized by providing several through holes on the mounting frame 1, with fixing nails 18 inserted into the through holes, and the mounting frame 1 is fixed to the wall by the fixing nails 18.

[0058] The design was further optimized by installing an ear plate 19 on the mounting block 2, which is fixed to the back plate of the alarm body.

[0059] Adding shock-absorbing pads, such as rubber shock-absorbing pads, between the ear plate 19 and the back plate of the alarm body reduces the noise and risk of damage caused by vibration during the operation of the alarm body, and improves the service life of the alarm body.

[0060] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0061] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
