Description

[0002] Anti-peeping early warning device is used to detect and prevent illegal peeping behavior, and protect the safety of privacy and sensitive information. Its working principle is mainly based on radio wave detection, optical detection and electromagnetic induction. Radio wave detection is to monitor the specific frequency radio signals emitted by peeping devices in the surrounding environment; optical detection is to use specific light emission to capture the special optical signals generated by the reflection or refraction of peeping device lenses; electromagnetic induction is to detect the weak electromagnetic field changes generated by peeping devices when they are working. When signals characteristic of peeping devices are detected, the device will issue an early warning.

[0003] In the current anti-peeping early warning device technical field, common anti-peeping early warning devices often use simple shell protection structures. When in use, the device is directly placed in the target monitoring area, and signal transmission and reception is realized by relying on the top antenna to achieve anti-peeping early warning function. When the device falls accidentally, only the rigid material of the shell passively bears the impact force.

[0026] Reference Figure 2 - Figure 4 The buffer assembly includes a limiting plate 12, which is threadedly connected to the inner wall of the mounting plate 3 by bolt A. This limiting plate 12 restricts the movement direction of the movable rod 20, ensuring the stability of the damping pad 10's movement trajectory. A housing 5 is fixedly connected to the outer side of the mounting plate 3, providing protection for components such as the movable rod 20 and spring B15, preventing interference from external factors.

[0028] Referring to Figure 2 , Figure 3 A detachable assembly is arranged on the damping pad 10, the detachable assembly comprises an extension block 14, the extension block 14 is fixedly connected to the outer side of the limiting plate 12 and connected to the inner wall of the mounting plate 3 through a bolt A, and is used for fixing the limiting plate 12, the extension block 14 is threadedly connected to the inner wall of the mounting plate 3 through the bolt A, so that the limiting plate 12 is convenient to disassemble and assemble, the replacement of the damping pad 10 is realized, the inner wall of the mounting plate 3 is provided with a sliding groove 17, the sliding groove 17 is used for providing a sliding track for the ball 16, so that the damping pad 10 can move smoothly, the top and the bottom of the damping pad 10 are fixedly connected with the ball 16, the ball 16 slides in the sliding groove 17 when the damping pad 10 moves, and the friction is reduced, the sliding groove 17 is matched with the ball 16, so that the ball 16 can stably slide in the sliding groove 17, the sliding groove 17 is arc-shaped, is matched with the ball 16, so that the damping pad 10 moves more flexibly, and the surface of the ball 16 is movably connected with the inner wall of the sliding groove 17, so that the damping pad 10 can smoothly move and abut against the sliding plate 11 under the action of the spring B15;

[0029] Referring to Figure 1The bottom of the anti-peeping early warning device main body 1 is provided with a hemispherical base 4, which uses the principle of the unbreakable doll to make the center of gravity of the device downward, thereby playing a role in preventing tilting and buffering the impact force of falling. The top of the hemispherical base 4 is threadedly connected with a support plate 13 through a bolt B, thereby realizing the stable connection of the hemispherical base 4 and the support plate 13. The top of the support plate 13 is fixedly connected with a connecting plate 6 for connecting the support plate 13 and the sliding plate 11 and transmitting the impact force. The top of the connecting plate 6 is movably penetrated through the bottom of the mounting plate 3 and is fixedly connected with the bottom of the sliding plate 11, so as to transmit the impact force received by the hemispherical base 4 to the sliding plate 11 and trigger the buffering assembly to work.

[0030] Working principle: when using the device, first, the installation operation is performed. The hemispherical base 4 is fixedly connected with the support plate 13 through the bolt B to ensure stable connection and prevent loosening during use. Then, the connecting plate 6 is penetrated through the bottom of the mounting plate 3 and is fixedly connected with the bottom of the sliding plate 11. Subsequently, the spring A8 is accurately sleeved on the surface of the cylinder body 7 and the telescopic rod 9, the movable rod 20 is installed on the inner wall of the cylinder body 7, the bottom end of the spring A8 is fixedly connected with the top of the sliding plate 11, and the spring A8 can normally play the elastic role. Then, one end of the spring B15 is fixedly connected with the inner wall of the shell 5, and the other end is connected with one end of the movable rod 20. The other end of the movable rod 20 is penetrated through the limiting plate 12 and is fixedly connected with the damping pad 10. The limiting plate 12 is installed on the inner wall of the mounting plate 3 through the bolt A, and the bolt A is tightened to stably install the limiting plate 12. Finally, the damping pad 10 with the ball 16 is installed in the sliding groove 17 on the inner wall of the mounting plate 3, so that the ball 16 slides with the inner wall of the sliding groove 17, and the installation of the whole device is completed.

[0031] After installation, the user holds the anti-peeping early warning device main body 1 on both sides by the anti-slip pattern, and places the device stably in the area where anti-peeping monitoring is needed. At this time, the antenna 2 at the top of the device starts to play a role in receiving and transmitting signals, thereby realizing the anti-peeping early warning function. In daily use, the hemispherical base 4 uses the principle of the unbreakable doll to always keep the center of gravity of the device downward, thereby playing a good role in preventing tilting and reducing the risk of accidental tilting and falling of the device.

[0032] If the device is accidentally dropped during use, the hemispherical base 4 will first collide with the ground, and due to its downward center of gravity, the impact force will be quickly transmitted to the sliding plate 11 through the support plate 13 and the connecting plate 6, driving the sliding plate 11 to move upward. During the upward movement of the sliding plate 11, its two sides will press the movable rod 20 and the spring A8 cooperating with the cylinder body 7, the movable rod 20 slides smoothly on the inner wall of the cylinder body 7, compressing the spring A8, which absorbs the longitudinal impact force by its own elasticity; at the same time, the damping pads 10 on both sides will quickly approach each other under the action of the transverse elastic potential energy of the spring B15, until they are tightly attached to the two sides of the sliding plate 11. In this process, the movable rod 20 slides on the inner wall of the limiting plate 12, which precisely guides the damping pad 10 and further enhances the buffering effect. When the longitudinal elastic potential energy of the spring A8 is released, the vibration energy is converted into heat energy or other forms of energy through the contact between the two sides of the sliding plate 11 and the damping pad 10, so that the vibration amplitude gradually decreases, thereby effectively reducing the impact force on the anti-peeping warning device main body 1 and protecting the internal precision components from damage.

[0033] With the long-term use of the device, when it is found that the damping pad 10 is worn and affects the buffering effect, it needs to be replaced and maintained. At this time, the bolt A is unscrewed with a tool to release the locking state of the limiting plate 12, and under the action of the transverse elastic potential energy of the spring B15, the limiting plate 12 inside the moving mounting plate 3 is cooperated. Since the balls 16 at the top and bottom of the damping pad 10 slide on the inner wall of the sliding groove 17, the frictional force of the damping pad 10 during transverse movement can be reduced, so that the limiting plate 12, the ball 16, the damping pad 10, the outer shell 5, the movable rod 20 and the spring B15 can be smoothly taken out from the inside of the mounting plate 3. After replacing the worn damping pad 10 with a new one, follow the reverse order of the installation process to reinstall each component in turn, ensure that each component is installed in place and connected firmly, complete the maintenance operation of the device, and make the device have good anti-falling performance again.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features, as long as they are within the spirit and principles of the present application.
