Detailed Implementation

[0030] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] like Figures 1-6 As shown, the sound and light alarm includes a base 1, a fixing groove 2, an anti-slip texture 3, a screw 4 installed on the base 1, a nut 5 installed on the screw 4, a spring 6 installed on the screw 4 and the nut 5, and the spring 6 is connected to an external power supply.

[0032] The base 1 is equipped with a top cover 7, the top cover 7 is equipped with a middle clip 8, the middle clip 8 is equipped with a main board 9 that matches the spring clip 6, the main board 9 is equipped with a buzzer 10, the top cover 7 is equipped with a lampshade 11, and the top cover 7 is equipped with a sound amplification channel 13.

[0033] Working principle explanation:

[0034] Example 1, as Figure 1 , Figure 2 and Figure 3 As shown, the base 1 is provided with a fixing groove 2, and the fixing groove 2 is provided with anti-slip texture 3 for fixing screws to fix the base 1 to the wall or other positions. It is worth noting that the base 1 is equipped with screws 4, and screws 4 and nuts 5 fix the spring 6. The external wiring is connected to the spring 6 through the base 1, and the spring 6 is connected to the main board 9, so that the main board 9, buzzer 10 and external wiring form a circuit. The buzzer 10 emits a warning sound, which is further amplified by the sound amplification channel 13.

[0035] Example 2, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment adds the following structure based on embodiment 1: the lampshade 11 is equipped with a first hook 14 that matches the upper cover 7. It is worth noting that when the lampshade 11 is installed on the upper cover 7, the first hook 14 is automatically fixed. This structural design makes the lampshade 11 easier and faster to install, and the fixing effect is better.

[0036] Example 3, as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, this embodiment adds the following structure based on embodiment 1: the upper cover 7 is provided with a first sliding groove 24, a spring 15 is installed in the first sliding groove 24, a limiting block 16 matching the first sliding groove 24 is installed in the spring 15, the buzzer 10 is provided with a limiting groove 17 matching the limiting block 16, the first sliding groove 24 is provided with a second sliding groove 28, and a pull rod 29 matching the second sliding groove 28 is installed in the limiting block 16. It is worth noting that when the buzzer 10 is installed on the upper cover 7, the limiting... When the limiting block 16 is compressed by the spring 15, it retracts into the first slide groove 24. When the limiting block 16 matches the limiting groove 17, the spring 15 rebounds and inserts the limiting block 16 into the limiting groove 17 for fixation. When disassembling, push the pull rod 29 to compress the spring 15 so that the limiting block 16 retracts into the first slide groove 24. At this time, the buzzer 10 can be separated from the top cover 7. This structural design makes the installation of the buzzer 10 more convenient and quick, and the fixing effect is better. At the same time, it avoids the buzzer 10 being clamped and deformed.

[0037] Example 4, as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, this embodiment adds the following structure based on embodiment 1: the upper cover 7 is equipped with a positioning bone 18 and a positioning post 19 that match the main board 9; the middle buckle 8 is equipped with a second hook 20 that matches the main board 9; and the middle buckle 8 is equipped with a vertical bone 21 that matches the upper cover 7. It is worth noting that when the upper cover 7, the middle buckle 8, and the main board 9 are installed, the positioning bone 18, the positioning post 19, and the vertical bone 21 play a role in limiting and positioning, and the second hook 20 plays a role in fixing. This structural design makes the installation and positioning of the equipment more convenient and the operation more convenient and faster.

[0038] Example 5, as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, this embodiment adds the following structure based on embodiment 1: the middle buckle 8 is equipped with a locking foot 22, and the base 1 is provided with a locking groove 23 that matches the locking foot 22. It is worth noting that when the middle buckle 8 is installed on the base 1, the locking foot 22 enters the locking groove 23 and rotates to fix it. This structural design makes the installation and positioning of the middle buckle 8 more convenient and the operation more convenient and faster.

[0039] Example 6, as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, this embodiment adds the following structure based on embodiment 1: the upper cover 7 is equipped with a first positioning point 25, and the base 1 is equipped with a second positioning point 26 and a third positioning point 27. It is worth noting that when the upper cover 7 is installed on the base 1, it can be positioned and fixed by the first positioning point 25, the second positioning point 26 and the third positioning point 27. The second positioning point 26 is the starting position of the upper cover 7 rotation, and the third positioning point 27 is the ending position of the upper cover 7 rotation. This structural design makes the positioning of the upper cover 7 and the base 1 more accurate and makes the installation of the upper cover 7 more convenient.
