Simple improvements to the method of the present invention based on the concept of the present invention fall within the scope of protection claimed by the present invention.

[0023] See also Figure 1-6 The utility model provides a caravan-mounted smoke alarm device with detachable edge, comprising a mounting base 1, a smoke alarm 2 being threadedly connected to the top of the mounting base 1, a connecting groove 3 being provided on the top of the mounting base 1, a mounting structure for installation being installed inside the connecting groove 3, the mounting structure comprising a telescopic slot 31 provided at the bottom of the connecting groove 3, a transmission rod 32 being slidably connected to the top of the telescopic slot 31, a coil spring 33 being fixedly connected to the side opposite to the connecting slot 3 of the transmission rod 32, a mounting bracket 34 being symmetrically fixedly connected to the top of the telescopic slot 31, an auxiliary wheel 35 being rotatably connected to the bottom of the mounting bracket 34, a vacuum suction cup 36 being fixedly connected to the bottom of the vacuum suction cup 36, a pull rod 37 being fixedly connected to the top of the pull rod 37, the top of the pull rod 37 passing through the bottom of the telescopic slot 31 and being located inside the telescopic slot 31;

[0024] A rope is fixedly connected to the top of the pull rod 37, which is wrapped around the outside of the auxiliary wheel 35 and then fixedly connected to the bottom of the transmission rod 32; the installation of the coil spring 33 can increase the firmness of the connection between the mounting base 1 and the smoke alarm 2.

[0025] Specifically, such as Figure 1 and Figure 4 As shown, a thread 1 4 is provided on the side surface of the inner portion of the connecting groove 3, a thread 2 5 is provided on the side surface of the lower portion of the smoke alarm 2, and a battery slot 6 is provided on the top of the smoke alarm 2;

[0026] The smoke alarm 2 is threadedly connected to the mounting base 1 through thread 1 4 and thread 2 5 , and the battery slot 6 is used to place the power supply battery.

[0027] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, the battery slot 6 is internally rotatably connected to a cover plate 7, and a fixing structure of the cover plate 7 is installed inside the battery slot 6. The fixing structure includes a rotation slot 71 opened on the inner side surface of the battery slot 6, and a clamping plate 72 is rotatably connected to the interior of the rotation slot 71;

[0028] A movable groove 73 is formed on the top of the cover plate 7. A coil spring 74 is fixedly connected to the inside of the movable groove 73. A clamping block 75 is movably connected to the top of the cover plate 7. A limit slider 76 is fixedly connected to the bottom of the clamping block 75. The limit slider 76 is adapted to the movable groove 73. An adapter plate 77 is fixedly connected to the left side of the clamping block 75.

[0029] First, place the battery inside the battery slot 6, then close the cover 7, and push the block 75 backward so that the cover 7 can be completely closed. Then release the block 75, and the elastic force of the coil spring 2 74 can push the block 75 so that the adapter plate 77 on the side of the block 75 is inserted into the interior of the card plate 72, thereby completing the fixation of the cover 7, effectively improving the safety and firmness of the battery placement, and preventing the battery from loosening or falling when the vehicle shakes.

[0030] Specifically, such as Figure 1 As shown, an alarm light 8 is fixedly connected to the top of the smoke alarm 2 and located on one side of the battery slot 6, and a buzzer 9 is fixedly connected to the top of the smoke alarm 2 and located on the other side of the battery slot 6;

[0031] When the smoke alarm 2 detects the presence of smoke, the buzzer 9 and the warning light 8 will simultaneously give visual and auditory warnings to the user, thereby improving the personal safety of the user.

[0032] The working principle and use process of the utility model are as follows: during use, the user first cleans out a flat and clean placement surface at a suitable position above the interior of the caravan compartment;

[0033] Then, the vacuum suction cup 36 of the mounting base 1 is placed on the placement surface, and the smoke alarm 2 is screwed to make the smoke alarm 2 and the mounting base 1 threadedly connected. During the threaded connection process, the smoke alarm 2 will exert downward pressure on the transmission rod 32, and the transmission rod 32 can pull the rope connected to its outer side during the descent process. With the assistance of the auxiliary wheel 35, the pull rod 37 is moved in the opposite direction, so that a vacuum state is generated at the connection between the vacuum suction cup 36 and the placement surface, so that the mounting base 1 and the smoke alarm 2 can be fixedly installed. This not only greatly increases the installation speed of the smoke alarm 2, but also avoids drilling holes in the placement surface and damaging the interior of the caravan compartment, effectively improving practicality and convenience and reducing the cost of use.

[0034] Finally, place the battery in the battery compartment 6 and close the cover 7, and the smoke alarm 2 can then operate normally.
