Description

Technical Field

[0001] This utility model relates to the field of fire early warning technology, and more specifically, it relates to a fire early warning device. Background Technology

[0002] Fire alarm devices are mainly used to detect smoke, high temperature or flame in the early stage of a fire. They alert people to evacuate and initiate fire-fighting measures through sound and light alarms, minimizing casualties and property losses. They are suitable for homes, shopping malls, office buildings and other places, and play a particularly important role in the golden escape time of 15-120 seconds in the early stage of a fire.

[0003] To prevent power outages during fires, existing fire alarms typically have their own independent power supply. This ensures the alarm functions properly and sounds during a fire. Because they have their own independent power supply, it is necessary to inspect and replace it periodically. The power socket for existing fire alarms is usually located on the mounting surface between the alarm and the wall. Therefore, when the independent power supply needs to be inspected or replaced, the fire alarm often needs to be removed from the wall, which is very inconvenient. Furthermore, existing fire alarms are usually attached to the wall with adhesives such as 3M glue. After removal, the adhesive often becomes ineffective or weakened, requiring replacement during reinstallation, resulting in wasted resources.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In one possible embodiment, please refer to Figure 1 , Figure 2 and Figure 3 As shown, a fire alarm device includes an alarm device body 1 and a mounting base 2. The alarm device body 1 and the mounting base 2 are slidably coupled. The mounting base 2 is provided with an upward-facing slot 17 and a recessed groove 18 communicating with the slot 17. A connecting block 19 that abuts against the recessed groove 18 is fixedly connected to the back of the alarm device body 1. The connecting block 19 is provided with a locking block 20 that engages with the slot 17. Thus, during installation, the mounting base 2 is installed on the wall, and then the alarm device body 1 is locked to the mounting base 2. Therefore, when the alarm device body 1 is damaged or needs to be repaired, it can be removed by simply sliding the alarm device body 1 upward. After the repair is completed, the alarm device body 1 can be reinstalled on the mounting base 2. The operation is simple and convenient, and it avoids the waste of adhesive.

[0024] For further details, please refer to Figure 2 , Figure 4 and Figure 5As shown, the alarm device body 1 is equipped with a power socket 3 for power supply installation. The alarm device body 1 also has a cavity 4 that slides into the power socket 3. Therefore, when metal needs to be inspected or replaced, simply pull the power socket 3 and replace the independent power supply; there is no need to disassemble the alarm device body 1, making power supply replacement simple and convenient. A metal gasket 5 is provided on the inner wall of the cavity 4, and a metal protrusion 6 is provided on the power socket 3 that abuts against the metal gasket 5. By installing the independent power supply in the power socket 3 and then sliding the power socket 3 into the cavity 4, the metal protrusion 6 of the power socket 3 aligns with the metal gasket 5. The pieces 5 abut against each other, thereby connecting the circuit inside the alarm device body 1 and enabling the alarm device body 1 to work normally. The inner wall of the cavity 4 is provided with symmetrically distributed limiting posts 7. Rubber strips 8 are fixedly connected to both sides of the power socket 3. The rubber strips 8 are provided with sliding grooves 9 that slide with the limiting posts 7. Through the sliding cooperation between the limiting posts 7 and the sliding grooves 9, the alarm device body 1 limits the power socket 3. When it is necessary to insert the power socket 3 into the cavity 4, force is applied to the rubber strips 8, causing the rubber strips 8 to deform, thereby enabling the limiting posts 7 to be smoothly inserted into the sliding grooves 9, realizing the limitation of the power socket 3 by the alarm device body 1.

[0025] For further details, please refer to Figure 2 , Figure 4 and Figure 5 As shown, a limiting mechanism is provided between the alarm device body 1 and the power socket 3 to limit the movement of the power socket 3. By setting the limiting mechanism, the stability of the installation of the alarm device body 1 and the power socket 3 can be ensured, so that the metal protrusion 6 on the power socket 3 can fully abut against the metal gasket 5, ensuring that the alarm device body 1 can work normally.

[0026] For further details, please refer to Figure 2 , Figure 4 and Figure 5 As shown, the limiting mechanism includes a limiting block 10 that slides with the power socket 3. The alarm device body 1 has a limiting groove 11 that engages with the limiting block 10. By engaging the limiting block 10 with the limiting groove 11, the alarm device body 1 limits the power socket 3. The power socket 3 has a groove 12. The limiting block 10 slides with the groove 12. An adjusting plate 13 is fixedly connected to one end of the limiting block 10 located in the groove 12. A guide surface 15 is provided on the side of the limiting block 10 away from the adjusting plate 13. A spring 14 is fixedly connected between the adjusting plate 13 and the inner wall of the groove 12. The spring 14 is sleeved on one end of the limiting block 10 located in the groove 12. A pull rope 16 is fixedly connected to one end of the power socket 3 located in the groove 12 for easy pulling of the power socket 3.

[0027] For details, please refer to Figure 2 , Figure 4 and Figure 5 As shown, when it is necessary to replace the independent power supply in the power socket 3, force is applied to the adjusting plate 13 to make it slide in the groove 12, causing the limiting block 10 to disengage from the limiting groove 11. Then, by pulling the pull rope 16, the power socket 3 is moved upward and slides out of the cavity 4 to replace the independent power supply. After the independent power supply is replaced, the power socket 3 is pressed downward to make the guide surface 15 of the limiting block 10 abut against the inner wall of the cavity 4, thereby causing the limiting block 10 to slide into the groove 12. When the limiting block 10 slides to be flush with the limiting groove 11, the limiting block 10 will rebound under the action of the spring 14 and re-engage with the limiting groove 11, thereby realizing the limiting of the power socket 3 by the alarm device body 1.
