Description

Technical Field

[0001] The utility model relates to the field of monitoring equipment, in particular to an anti-theft device for monitoring equipment. Background Art

[0002] With rising public awareness of safety and growing security demands, surveillance equipment has been widely used across various fields. In urban security systems, surveillance cameras, deployed throughout streets and alleys, have become a crucial component of public safety, used for real-time monitoring of traffic conditions, crime prevention, and investigation assistance. In commercial spaces such as shopping malls, banks, and office buildings, surveillance equipment helps protect property, monitor employee behavior, and provide evidence in consumer disputes. Furthermore, in residential communities, surveillance systems provide residents with a sense of security and ensure a safe living environment.

[0003] At present, there are many types of monitoring equipment that are disclosed and used. For example, a monitoring device disclosed in a Chinese patent with the publication number CN107035943A includes a monitoring pole and a camera arranged on the monitoring pole. The camera includes a chassis, a bracket and a lens. The chassis includes an upper chassis and a lower chassis. The lower chassis is provided with a ring track. The upper chassis is provided with a contact portion that matches the ring track. The bracket is provided on the upper chassis. Both ends of the lens are provided on the bracket through the cooperation of the shaft and the bearing. The monitoring pole includes a vertical pole body, a bracket, and a movable base. The power device includes a rotating motor for driving the upper chassis to rotate, a rotating motor for driving the lens to rotate, and a driving motor for driving the lower gear to rotate. Different from the existing technology, the present invention can monitor horizontally up and down, rotate left and right, and rotate 720° forward and backward without dead angles, and there is no need to manually disassemble the camera. It is motor-driven throughout the process, simple to operate, and saves time and effort.

[0004] Whether it's the surveillance equipment provided by the aforementioned patent or other types of equipment, when mounted high, they are simply secured to the mounting bracket with ordinary screws or simple clamps. Thieves can easily remove the screws and dismantle the surveillance equipment using simple tools such as screwdrivers or wrenches. Furthermore, existing surveillance equipment lacks effective alarm and monitoring linkage, meaning it doesn't issue a timely alarm when stolen. Due to the high-value components (such as high-definition cameras and storage devices) contained in surveillance equipment and its importance in security, it has become a target for thieves. Theft of surveillance equipment not only results in direct financial losses for the device owner, including the purchase and installation costs of the device itself, but also leads to a range of indirect losses. For example, in locations where security monitoring is crucial, such as bank vaults and jewelry stores, theft of surveillance equipment can prevent criminal activity from being recorded, making subsequent investigations more difficult and potentially leading to further security risks.

[0026] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0027] The following is a further description with reference to the accompanying drawings and specific embodiments: Example 1

[0028] like Figure 1 、 Figure 3 As shown, to enhance the anti-theft capabilities of monitoring equipment and prevent economic losses and a series of indirect losses caused by theft, this embodiment improves existing monitoring equipment. Specifically, a mounting bracket 2 is added to the top of an existing monitoring device (e.g., monitor 1). A pressure sensor 5 is mounted on this mounting bracket 2 and electrically connected to the processor of monitor 1. Therefore, data monitored by pressure sensor 5 can be transmitted to monitor 1 in real time. After receiving data from the pressure sensor, monitor 1 first analyzes the data. If the signal is an analog signal, it is converted to a pressure value based on a pre-defined conversion relationship (e.g., a voltage-to-pressure conversion formula). If the signal is a digital signal, the pressure data is analyzed according to the communication protocol. Monitor 1 allocates memory space to store historical pressure data. For example, an array or database can be used to store the most recent (e.g., 100) collected pressure data. A pressure change threshold is set based on specific application requirements. For example, if the pressure fluctuation range during normal operation is within ±0.1 MPa, 0.1 MPa can be used as the pressure change threshold. An appropriate algorithm is used to determine whether the pressure data has changed. A simple method is to compare the current pressure value with the previous pressure value. If the absolute difference is greater than a set threshold, the pressure data is considered to have changed. More complex algorithms can also be used, such as statistical analysis of historical data (calculating the average, standard deviation, etc.). When the current pressure value exceeds the normal range based on historical data statistics, the pressure data is considered to have changed. Monitor 1 and the method for monitoring 1 to receive and determine whether the pressure data has changed are prior art and will not be described in detail here.

[0029] When the data monitored by the pressure sensor 5 changes, the monitor 1 will sound an alarm. When the monitor 1 is placed upright on a workbench, the mounting bracket 2 is placed against the workbench. At the same time, under the action of the monitor 1 and the mounting bracket 2, the pressure sensor 5 is placed against the workbench and can monitor the pressure applied by the monitor 1 and the mounting bracket 2. When the upright monitor 1 is lifted or stolen, the pressure data monitored by the pressure sensor 5 changes, and the monitor 1 is triggered to sound an alarm. When the pressure sensor 5 is installed at a high place through the mounting bracket 2, it is necessary to adjust the status of the mounting bracket 2 and fix the mounting bracket 2 to the installation surface with screws. At this time, the pressure sensor 5 can monitor the pressure applied by the monitor 1 and the mounting bracket 2. When the inverted monitor 1 is lifted or stolen, the pressure data monitored by the pressure sensor 5 changes, and the monitor 1 is triggered to sound an alarm.

[0030] like Figure 3 、 Figure 4 、 Figure 6 As shown, to achieve the above-mentioned monitoring and alarm functions, the mounting frame 2 includes a ring plate assembly 3 and a pressure sensor 5. The ring plate assembly 3 includes an inner ring plate 32 and an outer ring plate 31. The inner ring plate 32 is connected to the inner side of the outer ring plate 31 via a connecting frame 33. A slot 34 is provided at the bottom of the inner side of the inner ring plate 32, and the lower end of the slot 34 is configured as an opening. The pressure sensor 5 is mounted on the inner ring plate 32, and a clamping plate 51 is fixed to the pressure sensor 5. Therefore, the clamping plate 51 extends into the slot 34, ensuring stable installation of the pressure sensor 5 relative to the inner ring plate 32. In addition, the height of the clamping plate 51 is smaller than that of the slot 34. Therefore, the position of the pressure sensor 5 relative to the inner ring plate 32 can be adjusted as needed. For example, a pad can be added in the gap between the pressure sensor 5 and the monitor 1 to facilitate contact between the pressure sensor 5 and the mounting surface or workbench and to monitor pressure.

[0031] like Figure 2 、 Figure 3 、 Figure 4 As shown, in order to stably install the ring plate group 3 on the monitor 1, a threaded groove 11 is provided on the end face of the monitor 1, and a through hole 35 is provided on the connecting frame 33. At the same time, a bolt is provided through the through hole 35, and the end of the bolt is threadedly inserted into the threaded groove 11 at the top of the monitor 1. Therefore, under the action of the bolt, the ring plate group 3 can be stably installed on the end of the monitor 1, and at the same time, it is prevented that criminals can achieve the separation of the monitor 1 and the mounting frame 2 without disassembling the mounting frame 2.

[0032] like Figure 4As shown, in order to avoid the presence of bolts affecting the installation of the monitor 1, the inner ring plate 32 and the outer ring plate 31 are of equal height, the bottom surface of the connecting frame 33 is flush with the bottom surfaces of the inner ring plate 32 and the outer ring plate 31, and the top surface is lower than the top surfaces of the inner ring plate 32 and the outer ring plate 31. Therefore, the head of the bolt is located in the space formed by the connecting frame 33 and the ring plate.

[0033] like Figure 3 As shown, in order to adjust the position of the mounting frame 2 as needed and install the monitor 1 at a high location, the mounting frame 2 also includes multiple connecting plates 6, and the multiple connecting plates 6 are evenly distributed along the circumference of the ring plate group 3. When the monitor 1 needs to be installed at a high location, the end of the connecting plate 6 is pulled out to protrude from the ring plate group 3, and screws are inserted through the protruding end.

[0034] like Figure 4 、 Figure 7 As shown, specifically, a receiving groove 37 is provided at the intersection of the connecting frame 33 and the outer ring plate 31. The width of the receiving groove 37 is greater than the width of the connecting frame 33. A protrusion 36 is fixedly provided on the inner side of the connecting frame 33, extending along the length of the connecting frame 33. A support plate 61 is fixedly provided on the side of the connecting plate 6. A groove 62 is provided on the side of the support plate 61, extending along the length of the support plate 61 and having an open end. The support plate 61 is installed in the connecting frame 33, and the protrusion 36 is located in the groove 62. Therefore, with the cooperation of the protrusion 36 and the groove 62, the support plate 61 is stably and movably installed in the connecting frame 33, providing convenience for pulling out the connecting plate 6 as needed. When the monitor is placed on the workbench, the connecting plate 6 is immersed in the receiving groove 37, preventing the device from occupying a large space. Example 2

[0035] like Figure 4 、 Figure 5 As shown, based on Example 1, in order to ensure stable installation of the connecting plate 6 relative to the ring plate assembly 3, the mounting frame 2 further includes a limiting ring plate 4. The limiting ring plate 4 is located between the outer ring plate 31 and the inner ring plate 32, and the outer diameter of the limiting ring plate 4 is equal to the inner diameter of the outer ring plate 31. The limiting ring plate 4 is supported on the connecting frame 33, enabling flexible installation of the limiting ring plate 4 and facilitating the lifting of the limiting ring plate 4 as needed to adjust the connecting plate 6. In addition, the top surface of the limiting ring plate 4 is lower than or equal to the top surface of the outer ring plate 31 to avoid being affected by the presence of the limiting ring plate 4.

[0036] like Figure 5 、 Figure 7As shown, a plurality of connecting grooves 41 are provided on the lower side surface of the limiting ring plate 4, and a limiting plate 42 is fixedly provided in each connecting groove 41. A plurality of limiting grooves 63 are provided on the support plate 61, and the plurality of limiting grooves 63 are distributed along the length direction of the support plate 61. The support plate 61 is provided through the connecting groove 41, and the limiting plate 42 is inserted into a certain limiting groove 63, so that the connecting plate 6 is stably installed relative to the ring plate group 3, and the position of the connecting plate 6 can be adjusted when the limiting ring plate 4 is lifted, which provides convenience for realizing the installation of the monitor 1 at a high or low place.

[0037] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
