[0030] like Figures 1 to 6 As shown in the figure, this embodiment provides a rechargeable home alarm, which includes an alarm body 1, a charging hole 2 on one side of the alarm body 1, a charging head 4 installed inside the charging hole 2, and a charging cable 3 fixedly connected to the end of the charging head 4 away from the charging hole 2.

[0031] A connecting ring 5 is movably connected to the outer surface of the charging cable 3. The outer surface of the connecting ring 5 has an external thread 6. A threaded groove 7 is opened inside the alarm body 1. The threaded groove 7 is located outside the charging hole 2, and the external thread 6 is located inside the threaded groove 7 and is threadedly connected to it. Figure 5 As shown, the inner side of the connecting ring 5 is provided with a sliding groove that is compatible with the charging cable 3, which facilitates the sliding operation of the connecting ring 5 and its rotation operation. It also limits the charging head 4 to ensure that the charging head 4 will not detach from the charging hole 2. Furthermore, a rotating groove with a slightly larger diameter is provided on one side of the sliding groove, which is larger than the diameter of the charging head 4, so that it can rotate along the outer surface of the charging head 4 to facilitate the threaded connection between the external thread 6 and the threaded groove 7. Through the design of these two features, the charging head 4 and the charging hole 2 can be better and more tightly connected, avoiding the phenomenon of separation between the two, thereby allowing the alarm body 1 to be charged more fully.

[0032] One end of the connecting ring 5 is fixedly connected to a drive ring 8. The drive ring 8 is located at the end away from the external thread 6. The outer surface of the drive ring 8 is fixedly connected to a protrusion 9. The protrusion 9 is arranged in a circular array. The arrangement of the protrusion 9 can increase the friction between the operator and the protrusion, thereby facilitating the driving operation of the connecting ring 5.

[0033] A limiting ring 10 is fixedly connected to the outer surface of the charging cable 3. The limiting ring 10 is located at the end away from the charging head 4. The connecting ring 5 and the driving ring 8 are located between the limiting ring 10 and the charging head 4. The limiting ring 10 and the charging head 4 cooperate to prevent the driving ring 8 and the connecting ring 5 from separating from the charging cable 3.

[0034] The bottom of the alarm body 1 is provided with mounting holes 11. The mounting holes 11 are evenly distributed at the four corners of the alarm body 1. The alarm body 1 can be installed in the designated area by bolts passing through the mounting holes 11, so that the alarm body 1 can be installed stably and thus increase its stability.

[0035] The bottom of the alarm body 1 is equipped with suction cups 12, which are arranged at equal intervals. Multiple sets of suction cups 12 are located inside multiple sets of mounting holes 11. One end of each suction cup 12 is fixedly connected to a rectangular pipe 13. Multiple sets of rectangular pipes 13 are connected through the rectangular pipes 13 and fixed inside the alarm body 1. One end of each set of rectangular pipes 13 extends to the inside of the alarm body 1 and is fixedly connected to the rectangular pipe 13, which facilitates the fixation of the suction cups 12. At the same time, the multiple sets of suction cups 12 are connected to the inside of the rectangular pipes 13. The suction cups 12 can initially fix the alarm body 1 in a designated position, which facilitates the installation of the alarm body 1. Meanwhile, one side of the suction cup 12 and one side of the alarm body 1 are not on the same horizontal plane. One side of the suction cup 12 can preferentially contact the wall, which facilitates the initial positioning of the alarm body 1.

[0036] Both ends of the rectangular pipe 13 are fixedly connected to flow pipes 14, which correspond to each other. The ends of the two sets of flow pipes 14 away from the rectangular pipe 13 extend to the outside of the alarm body 1, which facilitates the transmission of air between the suction cup 12 and the inside of the rectangular pipe 13.

[0037] Airbags 15 are provided on both sides of the alarm body 1. The ends of the two sets of flow pipes 14 away from the rectangular pipe 13 extend to the outside of the alarm body 1 and are fixedly connected to the airbags 15. The suction cup 12, the rectangular pipe 13, the flow pipe 14 and the airbags 15 are connected, which makes it easy to adjust the inner pressure of the suction cup 12 so that the suction cup 12 can contact or detach from the wall, thereby facilitating the installation and removal of the alarm body 1.

[0038] When in use, insert the charging head 4 into the charging hole 2 and push the drive ring 8 to move the connecting ring 5 toward the charging hole 2. When the two are in contact, rotate the drive ring 8 to make the connecting ring 5 rotate, and the external thread 6 rotates with the rotation of the connecting ring 5, so that it slowly connects with the thread groove 7 until the inner side of the connecting ring 5 is in contact with one end of the charging head 4 to complete the power connection. This method is simple to operate and can make the connection between the charging head 4 and the charging hole 2 more tight, avoiding the problem of insufficient charging of the alarm body 1.

[0039] When installing the alarm body 1, the alarm body 1 can be placed in the designated area and the suction cup 12 can be made to contact the wall. At the same time, the airbag 15 is pressed so that the air inside it flows through the flow tube 14 and the rectangular pipe 13 to the inside of the suction cup 12. At this time, the gas inside the suction cup 12 is compressed and a negative pressure is generated, which causes the air around the suction cup 12 to flow and form a suction force, so that the suction cup 12 can be firmly attached to the wall. This allows the alarm body 1 to be initially positioned in the designated area. Then, the alarm body 1 can be fixed in the designated area by passing the bolt through the mounting hole 11. This makes the installation of the alarm body 1 easier and avoids the need to hold the alarm body 1 with one hand and turn the bolt with the other hand during installation.

[0040] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
