Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0025] A quick-install modular smoke alarm system comprises an alarm body 1, a mounting plate 2 is arranged on the top of the alarm body 1, the mounting plate 2 is installed on the ceiling, a docking cavity 3 is provided inside the alarm body 1, and both sides of the docking cavity 3 and the inner cavity of the alarm body 1 are provided with a snap-in groove 4, a docking terminal 5 adapted to the inner cavity of the alarm body 1 is fixedly installed on the bottom of the mounting plate 2, a movable cavity 7 is provided on one side of the docking terminal 5, a spring fixing part 6 is fixedly installed in the inner cavity of the movable cavity 7, and bayonet pins 9 located on both sides of the spring fixing part 6 are slidably installed on both sides of the inner cavity of the docking terminal 5, one end of the bayonet pin 9 extends to the outside of the docking terminal 5, and a spring 8 is fixedly connected to the end of the bayonet pin 9 facing the spring fixing part 6, and the end of the spring 8 away from the bayonet pin 9 is fixedly connected to the spring fixing part 6, and a positioning component adapted to the bayonet pin 9 is provided in the inner cavity of the docking cavity 3, and the bayonet pin 9 is adapted to the snap-in groove 4.

[0026] The specific usage process is as follows: First, according to the number of installations, the corresponding number of modules, that is, the mounting plate 2, the docking terminal 5 and all the components arranged on the mounting plate 2 and the docking terminal 5, are installed in sequence on the ceiling according to the appropriate spacing. This installation work can be completed in one work, because the mounting plate 2 has a simple structure, the position of the notch 15 is also more conspicuous, and the screws can be quickly and easily inserted. Compared with the covered screw holes on the traditional alarm, there is no covering structure around the notch 15 and the screw hole 16 on the mounting plate 2. Even if the user is on the ladder, there is no need for too much movement or adjustment of posture, and the screws can be quickly inserted into the corresponding notch 15 and the screw hole 16. In this way, when the user installs the upper module, Completing the installation work quickly can also ensure the safety of the user's work. Compared with the traditional installation method, it is safer and more efficient, and provides convenience for users. During installation, just insert the screw into the screw hole 16 and tighten it. The setting of the notch 15 allows the screw to be "hidden" in the notch 15, so that the alarm body 1 and the mounting plate 2 can be better matched, improving the aesthetics of the alarm after assembly. Next, the lower module can be installed, that is, the alarm body 1 and all the structures set on the alarm body 1. During installation, the user can decide whether to use a ladder according to the height of the ceiling. The following is an explanation of using a ladder. The user places the ladder in a suitable position, picks up the lower module, steps on the ladder, and puts the lower module The block is lifted, and then the docking cavity 3 on the alarm body 1 is aligned with the docking terminal 5 and snapped into place, so that the docking terminal 5 extends into the docking cavity 3. At this time, the two relative bayonet pins 9 will be snapped into the corresponding snap-in grooves 4. Then the user rotates the alarm body 1. At this time, as the alarm body 1 rotates, the bayonet pin 9 is squeezed by the inner wall of the docking cavity 3 and will be squeezed into the active cavity 7. At the same time, the bayonet pin 9 will also compress the spring 18, and then the bayonet pin 9 enters the docking cavity 3. The user then rotates the alarm body 1. At this time, the bayonet pin 9 will contact the protrusion 10. Under the squeezing of the protrusion 10, the bayonet pin 9 is completely retracted into the active cavity 7 and the spring 18 is compressed again. The alarm body 1 is rotated again. When the bayonet pin 9 rotates to the slot 18 with the alarm body 1, the bayonet pin 9 will Under the action of spring 1 8, it pops up in the direction away from the spring fixing member 6 until it is stuck in the slot 18, so that the positioning and fixing of the docking terminal 5 can be completed. When the bayonet pin 9 moves, the positioning pin 13 also arranged on the docking terminal 5 will move in the "front" of the bayonet pin 9, that is, in the process of the bayonet pin 9 being stuck in the slot 18, the positioning pin 13 will also be squeezed by the positioning member 11 and retracted into the spring slot 17. At the same time, the positioning pin 13 will also compress the spring 2 14, and then according to the moving trajectory of the positioning pin 13 and as the positioning pin 13 moves, the positioning pin 13 will be stuck in the first positioning hole 12 under the action of the spring 2 14, and then as the docking terminal 5 rotates, the positioning pin 13 will move out of the current positioning hole 12.It retracts back into the spring slot 17 again, and then snaps into the next positioning hole 12 until the bayonet pin 9 is snapped into the slot 18. Specifically, when the mounting plate 2 and the docking end head 5 rotate, all the positioning pins 13 and the second spring 14 will be driven to move, so that the position of the positioning pin 13 will change with the rotation of the docking end head 5. Then, during the rotation of the docking end head 5, the positioning pin 13 will be snapped into the positioning hole 12 close to "itself" under the action of the second spring 14, and then moved out of the current positioning hole 12. When the positioning pin 13 moves out of the positioning hole 12, the second spring 14 will be compressed. After the positioning pin 13 rotates to the position of the next positioning hole 12, it will be snapped into the current positioning hole 12 under the action of the second spring 14. This reciprocating cycle is repeated until the installation of the alarm body 1 and the docking terminal 5 is completed. Under the action of the positioning hole 12 and the positioning pin 13, the alarm body 1 can be further positioned to ensure the stability of the alarm body 1 after installation. In this way, the lower module is installed on the upper module.

[0027] Therefore, a modular installation structure design is adopted. When the user installs the smoke alarm, the user only needs to buckle up and then twist to assemble the two modules together, thereby completing the installation of the smoke alarm, saving a lot of installation time, increasing the installation speed of the smoke alarm, improving the user's installation efficiency, and providing convenience for the user's installation work.
