[0027] Example 1

[0028] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a door and window burglar alarm, including a mounting plate 1, an alarm body 2 disposed on the front side of the mounting plate 1, mating holes 3 formed on the surface of the mounting plate 1, and a mounting mechanism 4 and a stabilizing mechanism 5 disposed on the front side of the mounting plate 1.

[0029] Mounting mechanism 4 is used to quickly install the alarm body 2, improving its practicality;

[0030] Stabilizing mechanism 5 is used to clamp the alarm body 2 after it is installed, thereby improving the stability of the alarm after installation.

[0031] Specifically, the installation mechanism 4 enables the rapid installation of the alarm body 2, improving its practicality, while the stabilizing mechanism 5 clamps the alarm body 2 after installation, enhancing the stability of the alarm after installation.

[0032] Furthermore, the mounting plate 1 is fixed to the door or window, and then the protrusion 401 is inserted into the groove 405. The alarm body 2 is quickly installed by the cooperation of the locking block 403 and the slot 406. The alarm body 2 is clamped by the cooperation of the bidirectional screw 502 and the clamping block 503.

[0033] A transparent shell 13 is provided on the front side of the mounting plate 1, and a rubber rod 14 is fixedly connected to the rear side of the transparent shell 13. A mounting hole 15 for use with the rubber rod 14 is opened on the front side of the mounting plate 1. The rubber rod 14 on the rear side of the transparent shell 13 is inserted into the mounting hole 15 on the front side of the mounting plate 1. The friction of the rubber rod 14 makes the transparent shell 13 connected to the front side of the mounting plate 1, which can provide a certain degree of protection for the alarm body 2, and at the same time facilitate the observation of the working status of the alarm body 2.

[0034] Example 2

[0035] The second embodiment of this utility model provides a door and window anti-theft alarm. The installation mechanism 4 includes a protrusion 401 fixedly connected to the front side of the installation plate 1. A spring 402 is provided on the inner wall of the protrusion 401. The bottom end of the spring 402 is fixedly connected to the inner wall of the protrusion 401. A locking block 403 is fixedly connected to the top end of the spring 402. The surface of the locking block 403 is slidably connected to the inner wall of the protrusion 401. A pressure block 404 is slidably contacted on the top of the locking block 403. One side of the pressure block 404 is fixedly connected to the alarm body 2. A slot 406 is provided on the rear side of the alarm body 2. A groove 405 is provided on the top wall of the inner cavity of the slot 406. The surface of the protrusion 401 is slidably connected to the inner wall of the groove 405. The surface of the locking block 403 is slidably connected to the inner wall of the slot 406. The pressure block 404 is used in conjunction with the mating hole 3.

[0036] Specifically, the combination of spring 402 and locking block 403 enables the rapid installation and disassembly of the alarm body 2, which is easy to operate, improves installation efficiency, and enhances the practicality of the device.

[0037] Furthermore, when installing the alarm body 2, the protrusion 401 is aligned with the groove 405 and inserted. As the alarm body 2 approaches the mounting plate 1, the pressure block 404 presses against the locking block 403, causing the locking block 403 to compress the spring 402 and move downwards. When the slot 406 aligns with the locking block 403, the spring 402 returns to its original position, pushing the locking block 403 into the slot 406, thus completing the installation of the alarm body 2.

[0038] The rear side of the alarm body 2 is provided with a movable groove 6, which is connected to the slot 406. A pressure rod 7 is slidably connected to the inner wall of the movable groove 6. The bottom of the pressure rod 7 contacts the slot 403. A tension spring 8 is fixedly connected to the top of the pressure rod 7. A fixing block 9 is fixedly connected to the top of the tension spring 8. One side of the fixing block 9 is fixedly connected to the alarm body 2. A connecting rod 10 is slidably connected to the inner wall of the fixing block 9. The bottom of the connecting rod 10 passes through the fixing block 9 and is fixedly connected to the pressure rod 7. The tension spring 8 is sleeved on the outer periphery of the connecting rod 10. When disassembling the alarm body 2, press the connecting rod 10. The connecting rod 10 pushes the pressure rod 7 downward and stretches the tension spring 8. The pressure rod 7 pushes the locking block 403 downward and disengages it from the slot 406. At this time, the alarm body 2 can be removed. Finally, release the pressure of the connecting rod 10. The cooperation of the pressure rod 7, the tension spring 8 and the connecting rod 10 makes the unlocking operation of the locking block 403 more convenient and smooth, improving the ease of installation and disassembly of the alarm body 2.

[0039] Example 3

[0040] The second embodiment of this utility model provides a door and window anti-theft alarm. The stabilizing mechanism 5 includes a crossbar 501 fixedly connected to the front side of the mounting plate 1. The inner wall of the crossbar 501 is rotatably connected to a bidirectional lead screw 502 through a bearing. The surface of the bidirectional lead screw 502 is connected to a clamping block 503.

[0041] Specifically, the anti-slip pad 12 clamps the alarm body 2, improving the stability of the alarm after installation.

[0042] Furthermore, rotating the bidirectional lead screw 502 causes the two clamping blocks 503 to move towards or away from each other along the slider and groove on the limiting plate 11 when the bidirectional lead screw 502 is rotated. After the alarm body 2 is installed, rotating the bidirectional lead screw 502 causes the two clamping blocks 503 to move towards each other, clamping the alarm body 2 through the anti-slip pad 12.

[0043] A limiting plate 11 is fixedly connected to the bottom of the crossbar 501, and the bottom of the clamping block 503 is slidably connected to the limiting bar via a slider and a groove. The limiting plate 11 provides a limit to the movement of the clamping block 503, making the movement of the clamping block 503 more stable.

[0044] An anti-slip pad 12 is fixedly connected to one side of the clamping block 503. The anti-slip pad 12 effectively increases the clamping force of the clamping block 503 on the alarm body 2, further improving the stability of the alarm body 2 after installation, and also protecting the alarm body 2.

[0045] Working principle:

[0046] First, fix the mounting plate 1 on the door or window. When installing the alarm body 2, align the protrusion 401 with the groove 405 and insert it. As the alarm body 2 approaches the mounting plate 1, the pressure block 404 presses the locking block 403, causing the locking block 403 to compress the spring 402 and move downward. When the slot 406 is aligned with the block 403, the spring 402 resets and pushes the block 403 into the slot 406, thus installing the alarm body 2. The cooperation of the spring 402 and the block 403 enables quick installation and removal of the alarm body 2, simplifying operation, improving installation efficiency, and enhancing the practicality of the device. Then, rotating the bidirectional lead screw 502 causes the two blocks 503 to move towards or away from each other along the slider and groove on the limiting plate 11 when the bidirectional lead screw 502 rotates. After the alarm body 2 is installed, rotating the bidirectional lead screw 502 causes the two blocks 503 to move towards each other, clamping the alarm body 2 with the anti-slip pad 12. Then, disassembly... When removing the alarm body 2, press the connecting rod 10. The connecting rod 10 pushes the pressure rod 7 downward and stretches the tension spring 8. The pressure rod 7 pushes the locking block 403 downward and disengages it from the slot 406. At this time, the alarm body 2 can be removed. Finally, release the pressure of the connecting rod 10. The cooperation of the pressure rod 7, the tension spring 8 and the connecting rod 10 makes the unlocking operation of the locking block 403 more convenient and smooth, improving the ease of installation and removal of the alarm body 2. Insert the rubber rod 14 on the back of the transparent shell 13 into the mounting hole 15 on the front of the mounting plate 1. The friction of the rubber rod 14 connects the transparent shell 13 to the front of the mounting plate 1, which can provide a certain degree of protection for the alarm body 2 and at the same time facilitate the observation of the working status of the alarm body 2.

[0047] In summary, the combination of the installation mechanism and the stabilization mechanism enables the rapid installation and removal of the alarm, and ensures a stable effect after installation.
