DETAILED DESCRIPTION

[0027] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explaining the present invention and are not intended to limit the present invention.

[0028] The following is combined with Figures 1-9 This embodiment is described in further detail.

[0029] Combined with attachment Figures 1-9 In this embodiment, an anti-dismantling device based on an Internet of Things remote alarm includes a base 100 that cooperates with a smoke alarm 102. A chamber is provided in the base 100. A plug-in column 300 is provided on the upper side of the smoke alarm 102. A plug-in block 301 is provided at the upper end of the plug-in column 300. A plug-in slot 700 communicating with the chamber and for inserting the plug-in block 301 is provided on the lower side of the base 100; a locking component is provided in the chamber for locking the plug-in block 301 inserted into the plug-in slot 700; a driving component is also provided in the chamber for driving the locking component to lock; an installation cavity 600 with an upper end opening is provided in the smoke alarm 102, and a cover plate 304 is installed at the opening of the installation cavity 600 through the installation component. An alarm component is provided in the installation cavity 600, and the alarm component is used to alarm when the plug-in block 301 is separated from the plug-in slot 700.

[0030] When this embodiment is actually used, the base 100 is fixed to the top of the wall by expansion bolts, and the plug-in block 301 is inserted into the cavity through the plug-in slot 700. Through the setting of the driving component, the driving component can drive the locking component to lock the plug-in block 301, so that the lower side of the plug-in block 301 can overlap the upper side of the locking component, thereby completing the hoisting of the smoke alarm 102. Specifically, the smoke alarm 102 is of an existing structure, which mainly includes a smoke sensor, a controller and a buzzer installed in the installation cavity 600. The smoke sensor is electrically connected to the controller, and the controller is electrically connected to the buzzer. When the smoke concentration in the environment monitored by the smoke sensor exceeds the standard, the smoke sensor sends a signal to the controller. After receiving the signal, the controller controls the buzzer to sound an alarm. At the same time, the alarm information is sent to the user through the Internet of Things technology, so that the user can quickly take corresponding measures to ensure safety. In actual use, the plug-in column 300 is fixedly mounted on the cover plate 304, and the plug-in block 301 is fixedly mounted at one end of the plug-in column 300. By setting the mounting assembly, the cover plate 304 can be disassembled and assembled at the opening position of the installation cavity 600, so that the installation cavity 600 can be opened so that the components in the installation cavity 600 can be installed. At the same time, the plug-in column 300 and the plug-in block 301 can be installed on the smoke alarm 102. Among them, when an outsider wants to release the lock of the locking assembly on the plug-in block 301, he needs to use a tool such as a screwdriver to control the driving assembly to release the lock of the locking assembly on the plug-in block 301; specifically, the driving assembly is located in the chamber, and a slide groove communicating with the chamber is provided on the lower side of the base 100, and one end of the slide groove is open, and a slidable shielding plate 101 is provided at the opening position. Through the setting of the shielding plate 101, the shielding plate 101 can shield the driving assembly, so that it is not easy for outsiders to find the driving assembly, thereby improving the anti-dismantling effect of the smoke alarm 102; Among them, when the locking component releases the lock on the plug-in block 301 and pulls the plug-in block 301 out of the plug-in slot 700, the alarm component is set to enable the alarm component to sound an alarm, thereby achieving the purpose of reminding the user, thereby better preventing the smoke alarm 102 from being disassembled.

[0031] Combine Figure 7-Figure 9 As shown, in this embodiment, the locking assembly includes a fixed ring 902 arranged on the side wall of the chamber, a plurality of mounting grooves are provided on the side wall of the fixed ring 902 along its radial direction, a movable locking tongue 701 is provided in the mounting groove, a rotatable gear ring 800 is provided on the side wall of the fixed ring 902, an arc groove 801 is provided on the side wall of the gear ring 800 corresponding to the locking tongue 701, and a driving column 802 extending into the arc groove 801 is provided on the side wall of the locking tongue 701.

[0032] In actual use of this embodiment, the fixing ring 902 is fixed to the side wall of the chamber by screws, and the mounting groove is adapted to the lock tongue 701, so that when the gear ring 800 is rotated, the gear ring 800 can drive the arc groove 801 to rotate, thereby causing the side wall of the arc groove 801 to squeeze the corresponding driving column 802, so that the driving column 802 can move along the arc groove 801, and then the driving column 802 can drive the corresponding lock tongue 701 to move, so that the lock tongue 701 can extend and retract within the fixing ring 902; In actual use, when the plug-in block 301 needs to be inserted into the chamber through the plug-in slot 700, the gear ring 800 is rotated to drive the driving column 802 through the arc groove 801 to drive the lock tongue 701 to retract out of the fixing ring 902, so that the plug-in block 301 can be inserted into the chamber through the plug-in slot 700. At this time, the gear ring 800 is rotated in the opposite direction to drive the lock tongue 701 to extend into the fixing ring 902, so that the lower side of the plug-in block 301 can overlap the upper side of the lock tongue 701, that is, the smoke alarm 102 is hoisted. A T-shaped annular groove 903 is provided on the side wall of the chamber along the circumference of the gear ring 800. A plurality of sliding posts 900 are provided on the side wall of the gear ring 800 along its circumference. One end of the sliding post 900 is provided with a slider 901 that extends into the annular groove 903 and slides. The slider 901 is arc-shaped. The arrangement of the annular groove 903, the sliding post 900, and the slider 901 allows the gear ring 800 to rotate and drive the slider 901 to slide along the annular groove 903 via the sliding post 900, thereby achieving rotatable installation of the gear ring 800. Specifically, the slider 901 is adapted to the annular groove 903 so that the lower side of the gear ring 800 can be pressed against the upper side of the fixing ring 902, thereby enabling the gear ring 800 to press the locking tongue 701 into the installation groove.

[0033] Combine Figure 8-Figure 9 As shown, in this embodiment, the driving assembly includes a rotating shaft rotatably arranged in the chamber, a gear 702 meshing with the gear ring 800 is fixedly provided outside the rotating shaft, and a notch 703 is provided at one end of the rotating shaft.

[0034] In actual use of this embodiment, the rotating shaft adopts a damping rotating shaft, thereby making it difficult for the rotating shaft to drive the gear 702 to rotate. When it is necessary to drive the gear ring 800 to rotate, the shielding plate 101 is slid along the slide groove to open the chamber. At this time, an outsider needs to use a screwdriver and align the screwdriver head with the notch 703 and insert it. The outsider can rotate the screwdriver to drive the rotating shaft to rotate, thereby causing the rotating shaft to drive the gear 702 to drive the gear ring 800 to rotate. In actual use, a sliding bar is fixed on the side wall opposite to the shielding plate 101, and a long groove for the sliding bar to slide is provided along the length direction of the side wall opposite to the slide groove. Through the setting of the sliding bar and the long groove, the shielding plate 101 can be slidably installed on the base 100.

[0035] Combine Figure 3-Figure 5 As shown, in this embodiment, the side walls at the opening of the mounting cavity 600 extend inwardly to form a lap joint 601, and the mounting assembly includes a mounting block 400 fixedly mounted on the lower side of the cover plate 304, and a slide rod 401 is relatively provided on the mounting block 400, and a slidable sliding bar 405 is provided on the slide rod 401, and a lap joint block 406 is provided at one end of the sliding bar 405; a spring 404 is provided on the slide rod 401 located between the sliding bar 405 and the mounting block 400, and the spring 404 is used to push the sliding bar 405 to drive the lap joint block 406 to move so that the lap joint block 406 can extend into the lower side wall of the lap joint 601; the cover plate 304 is also provided with a driving member for driving the lap joint block 406 to disengage from the lower side wall of the lap joint 601.

[0036] When the cover 304 is in practical use, the cover 304 is installed at the opening of the installation cavity 600 by pressing the two driving members so that the driving members can drive the corresponding sliding bar 405 to slide along the sliding rod 401 and compress the spring 404. At the same time, the sliding bar 405 can drive the bridging block 406 to slide along the sliding rod 401. When the cover 304 is in contact with the opening of the installation cavity 600, the driving member is released so that the spring 404 can push the sliding bar 405 to move, so that the sliding bar 405 can drive the bridging block 406 to move to the lower position of the bridging portion 601, so that the lower side wall of the bridging portion 601 can abut against the upper side wall of the bridging block 406, thereby enabling the cover 304 to be installed. In actual use, rubber pads are provided on the opposite side walls of the mounting block 400, and rubber pads are also provided on the side walls corresponding to the sliding bar 405. The provision of the rubber pads prevents the spring 404 from moving on the sliding bar 401. In order to prevent the sliding bar 405 from being pushed out of the sliding rod 401 due to the excessive elastic force of the spring 404, in this embodiment, one end of the sliding rod 401 is fixed to a stopper 403. The stopper 403 is configured to block the sliding bar 405, thereby effectively preventing the spring 404 from pushing the sliding bar 405 out of the sliding rod 401. The upper side wall of the sliding bar 405 abuts against the lower side of the cover plate 304, thereby preventing the sliding bar 405 from rotating, thereby enabling the bridging block 406 to be better docked on the bridging portion 601; Specifically, the mounting block 400 is fixedly mounted on the lower side of the cover plate 304 , and one end of the two sliding rods 401 is fixedly mounted on the corresponding side wall of the mounting block 400 .

[0037] Combine Figure 5 As shown, in this embodiment, a driving cavity 500 with an opening at one end is provided in the cover plate 304, and a notch 402 is provided on the bottom wall of the driving cavity 500 that passes through the cover plate 304. The driving member includes a driving plate 303 that is arranged in the driving cavity 500 and can slide. The driving plate 303 is L-shaped, one end of which is fixedly connected to the upper side wall of the sliding bar 405, and the other end extends out of the driving cavity 500.

[0038] In actual use of this embodiment, by pressing the end of the driving plate 303 extending out of the driving cavity 500, the driving plate 303 can move along the notch 402 into the driving cavity 500, thereby causing the driving plate 303 to drive the sliding bar 405 to drive the overlapping block 406 to separate from the overlapping portion 601, thereby releasing the installation of the cover plate 304 at the opening position of the installation cavity 600; Among them, a placement groove 704 connected to the plug-in groove 700 is provided on the side wall of the base 100. Through the setting of the placement groove 704, when the smoke alarm 102 is installed on the base 100, the protruding end of the driving plate 303 can be placed in the placement groove 704, thereby preventing outsiders from releasing the cover plate 304 from being fixed at the opening position of the installation cavity 600.

[0039] Combine Figure 3 As shown, in this embodiment, the alarm component includes a pressure sensor 302 installed on the plug-in block 301.

[0040] During actual use of this embodiment, the pressure sensor 302 is electrically connected to the controller. When the plug-in block 301 is inserted into the chamber through the plug-in slot 700, the pressure sensor 302 abuts against the corresponding side wall of the chamber. When the plug-in block 301 is pulled out of the chamber through the plug-in slot 700, the pressure sensor 302 sends a signal to the controller. After receiving the signal, the controller controls the buzzer to sound an alarm, thereby reminding the user that the smoke sensor is being disassembled.

[0041] When the smoke alarm 102 is actually used, the base 100 is first fixed to the top of the wall by expansion bolts. Then, the shielding plate 101 is slid to expose the notch 703. An outsider uses a screwdriver and aligns the screwdriver head with the notch 703 and inserts it, so that the outsider can rotate the screwdriver to drive the rotating shaft to rotate, thereby causing the rotating shaft to drive the gear 702 to drive the gear ring 800 to rotate. The rotation of the gear ring 800 can drive the driving column 802 to drive the lock tongue 701 to retract the fixing ring 902 through the arc groove 801, so that the plug-in block 301 can be inserted into the chamber through the plug-in slot 700. At this time, by rotating the gear ring 800 in the opposite direction, the gear ring 800 can drive the lock tongue 701 to extend into the fixing ring 902, so that the lower side of the plug-in block 301 can overlap the upper side of the lock tongue 701, that is, the hoisting of the smoke alarm 102 is achieved.

[0042] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
