[0028] A smart fire alarm terminal, such as Figures 1-6 As shown, the device includes a wall 1, a protective shell 2, and a mounting bracket 7. The protective shell 2 has slots 6 fixed at the four inner corners. The mounting bracket 7 has fastening blocks 16 rotatably connected to the four inner corners via spring shafts. The four sets of fastening blocks 16 are vertically aligned with the four sets of slots 6 and interlock with each other. The bottom of the four sets of fastening blocks 16 is fixed with a paddle 17. The bottom of the mounting bracket 7 is fixed with a retaining ring 13. A protective cover 14 is provided on the outside of the retaining ring 13. A retaining block 15 is fixed on the top of the inner side of the protective cover 14 and interlocks with the retaining ring 13. The protective cover 14 and the retaining ring 13 are both made of flexible plastic material.

[0029] The protective shell 2 has four corner slots fixed inside, which correspond to the fastening blocks 16 at the four corners inside the mounting bracket 7 via spring shafts and engage with each other. This ensures that the mounting bracket 7 can be securely installed under the protective shell 2, effectively preventing the alarm terminal from loosening or falling off due to external forces during use, thus improving the stability and reliability of the terminal. The bottom of each of the four fastening blocks 16 is fixed with a lever 17, so that when the mounting bracket 7 needs to be disassembled or maintained, simply move the lever 17 to rotate the fastening block 16, releasing its engagement with the slot 6, and easily remove the mounting bracket 7 from the protective shell 2. This greatly facilitates the maintenance and repair of the terminal. The bottom of the mounting bracket 7 is fixed with a retaining ring 13, and a protective cover 14 is provided on the outside of the retaining ring 13. The top of the inner side of the protective cover 14 is fixed with a retaining block 15, which engages with the retaining ring 13, providing protection for the sensing port 9 before installation. The protective cover 14 can be easily removed during use.

[0030] See Figure 1 , Figure 2 and Figure 3 The interior of the wall 1 is provided with an installation groove for the installation of the protective shell 2. The top of the protective shell 2 is fixed with a connecting plate 3, and fastening bolts 4 are provided at the four corners of the connecting plate 3. The connecting plate 3 is fixed to the wall 1 by four sets of fastening bolts 4.

[0031] The installation slot simplifies the installation process, allowing the protective shell 2 to be easily embedded in the wall 1, thus improving installation efficiency. The use of fastening bolts 4 provides reliable connection force, ensuring that the protective shell 2 will not loosen or fall off due to external forces during long-term use, thereby guaranteeing the reliability and safety of the smart fire alarm terminal.

[0032] See Figure 2 Several sets of through holes 5 are provided on both sides of the top of the protective shell 2 to provide channels for external cables to enter the protective shell 2.

[0033] The protective shell 2 has several sets of through holes 5 on both sides of its top, allowing the cables to pass through the protective shell 2 in an orderly manner and connect to the internal alarm body 8, thereby realizing signal transmission and normal operation of the equipment.

[0034] See Figure 3 , Figure 4 and Figure 5 The mounting bracket 7 is internally threaded to the alarm body 8, and the bottom of the alarm body 8 is provided with a sensor port 9, and a protective plate 10 is fixed to the outer side of the bottom of the alarm body 8.

[0035] The threaded connection also provides a convenient way to disassemble. When the alarm body 8 needs to be maintained or replaced, it can be easily removed from the mounting bracket 7.

[0036] See Figure 5 A sealing strip 11 is fixed to the top of the guard plate 10, and a sealing groove 12 is provided at the bottom of the mounting bracket 7 for the sealing strip 11 to engage and seal, and engages with the sealing groove 12.

[0037] During the installation of the alarm body 8, the sealing strip 11 rises along with the alarm body 8 via the protective plate 10, thereby achieving a tight sealing connection with the sealing groove 12. In addition, the cooperation between the sealing groove 12 and the sealing strip 11 also provides good shock absorption and cushioning, reducing the damage to the alarm body 8 caused by vibration or impact during use, and further improving the reliability and stability of the alarm.

[0038] See Figure 1 , Figure 2 and Figure 4 Rubber pads are provided on both sides of the paddle 17 to enhance friction with the operator's hands;

[0039] The operator can more easily hold and turn the lever 17, ensuring accuracy and stability even when hands are wet or gloves are worn, avoiding operational errors caused by slipping or slipping.

[0040] The implementation principle of this utility model is as follows: First, the protective shell 2 is installed into the mounting groove inside the wall 1 using the fastening bolts 4 at the four corners of the top connecting plate 3. Then, the alarm body 8 is inserted into the mounting groove reserved in the middle of the mounting bracket 7, and the alarm body 8 is rotated to make it threadedly fastened to the mounting bracket 7. While the alarm body 8 is threadedly fastened to the mounting bracket 7, the sealing strip 11 on the outer side of the bottom protective plate 10 of the alarm body 8 will engage and seal with the sealing groove 12 opened at the bottom of the mounting bracket 7. Then, the protective shell 2 is installed into the mounting groove inside the wall 1. The cover 14 engages with the retaining ring 13 at the bottom of the mounting bracket 7 via the internal retaining block 15, thereby providing protection for the sensor port 9 at the bottom of the alarm body 8 and preventing it from being corroded or damaged by external impurities during transportation and when not in use. Then, the external cable passes through the through holes 5 opened on both sides of the top of the protective shell 2 to make an electrical connection with the alarm body 8. Then, the four sets of fastening blocks 16 at the four corners of the mounting bracket 7 are inserted and engaged with the four sets of retaining slots 6 on the inside of the protective shell 2, thereby allowing the mounting bracket 7 to be stably installed at the bottom of the protective shell 2.

[0041] Afterwards, the locking block 15 and the locking ring 13 inside the protective cover 14 can be disengaged, allowing the sensor port 9 to contact the outside air for the alarm body 8 to perform a test. Finally, when the alarm body 8 inside the protective shell 2 needs to be periodically tested, the four sets of levers 17 below the mounting bracket 7 can be moved to rotate the fastening block 16, thereby disengaging the fastening block 16 from the slot 6, and the mounting bracket 7 can be easily removed from the bottom of the protective shell 2.
