Description

Technical Field

[0001] This application relates to the field of digital camera display anti-theft technology, and in particular to a digital camera anti-theft alarm. Background Technology

[0002] With the increasing popularity and frequency of use of digital cameras, the demand for displaying digital cameras in public places such as shopping malls and exhibitions is also growing. However, as high-value commodities, digital cameras face the risk of theft when displayed. Therefore, how to effectively prevent theft of digital cameras during displays has become an urgent problem to be solved.

[0003] Existing anti-theft technologies primarily rely on a combination of sensors and alarm devices, with the sensors connected to the alarm via cables. When the sensor detects a breach in the connection between the digital camera and the display stand, the alarm will immediately sound, alerting staff to take action. Relevant prior art, such as Chinese patent application "A Security Device for Anti-theft of Goods", application number: CN201921570790.1, discloses a device including a malleable patch and a contact sensor. The malleable patch is configured to deform and maintain its deformation under external force and is configured to adhere to the surface of the goods. The contact sensor is configured to adhere to the surface of the goods through the malleable patch. The contact sensor can be connected to a monitoring device for anti-theft of goods via a connecting device and / or cable. This design utilizes a patch device with a shape that can change and has a certain degree of plasticity, which can fix the contact sensor to the curved surface of the goods. Furthermore, due to the plasticity of the patch, it can adapt to the shape of different goods, ensuring that it always maintains consistency with the curved surface. This allows it to match goods of different shapes and avoids gaps at the edges and corners caused by inconsistent shapes, preventing easy detachment and ensuring a more secure adhesion of the patch.

[0004] The above are common anti-theft security devices for goods, but applying them to digital cameras presents inconvenience. Existing digital cameras generally consist of a camera body and optical lenses, and to meet different user needs, different types of optical lenses are required. Therefore, to better showcase the digital camera, it's necessary to display both the camera body and multiple optical lenses simultaneously. Using the aforementioned anti-theft security devices would require multiple units, which is cumbersome and unreasonable. Therefore, a digital camera anti-theft alarm is designed to provide anti-theft protection for digital camera products that need to be displayed. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a digital camera anti-theft alarm that is designed for digital camera products and can simultaneously meet the anti-theft protection needs of the camera body and optical lens, while also enabling the digital camera products to have a good display effect.

[0006] The technical solution adopted in this application is as follows: a digital camera anti-theft alarm, including a main unit, a telescopic bracket and at least one alarm element. The main unit and the telescopic bracket are respectively installed on the display table. The main unit is equipped with a control device. The camera body is installed on the main unit. The optical lens connected to the camera body is mounted on the telescopic bracket. The main unit surface is equipped with a first sensor and a second sensor respectively connected to the control device. The first sensor extends through the upper surface of the main unit and contacts the camera body. The second sensor extends through the lower surface of the main unit and contacts the display table surface. The alarm element is connected to the main unit through an anti-theft line. The alarm element corresponds to the optical lens one by one and is connected to the optical lens.

[0007] Compared with existing technologies, the advantages of this application are as follows: First, the alarm of this application integrates the anti-theft protection of the camera body and optical lenses into one system, avoiding the cumbersome process of setting up each optical lens separately in traditional anti-theft devices, thus reducing the complexity and cost of the equipment. Second, by equipping it with a telescopic bracket, the connected optical lenses can be displayed in conjunction with the camera body during the exhibition. The telescopic bracket can be adjusted as needed to accommodate different models and sizes of camera lenses, enhancing the product's applicability. Displaying the connected camera body and optical lenses provides better aesthetics and visibility, ensuring that users can clearly see the product's appearance and functions, improving the exhibition effect. Third, by setting up a first and a second sensor, the connection status between the camera body and the display platform can be monitored in real time. Once an abnormality occurs (such as the camera being removed), the control device in the main unit will provide anti-theft protection (such as sounding an alarm). Finally, this application is equipped with at least one alarm device, with each alarm corresponding to and connected to an optical lens. Therefore, this application can not only protect the camera body but also protect multiple optical lenses simultaneously, meeting the display needs of digital cameras with multiple optical lenses and improving the product's overall anti-theft capability.

[0008] In some embodiments of this application, the bottom of the telescopic bracket and the bottom of the main unit are provided with an adhesive layer and are fixedly connected to the display table surface through the adhesive layer, and the telescopic bracket is located in front of the main unit.

[0009] To fully demonstrate the functions of a digital camera, various optical lenses are fitted to the camera body, including a main lens that is connected to the camera body. Therefore, the telescopic bracket in this application is primarily for supporting the main lens, making the entire digital camera more stable and reliable.

[0010] In some embodiments of this application, the telescopic bracket includes, from top to bottom, a bracket, an inner rod, an outer tube, and a base. The bracket is connected to the top surface of the inner rod, and the outer tube is sleeved outside the inner rod and connected to the base. The inner rod and the outer tube are coaxially arranged, and the inner rod can move up and down relative to the outer tube under force. A locking bolt is installed on the outer tube, and the locking bolt abuts against the surface of the inner rod. Adjusting the locking bolt can fix or move the inner rod relative to the outer tube.

[0011] This design allows the inner rod to move up and down within the outer tube, enabling the bracket height to be adjusted as needed to accommodate different camera lenses of various models and sizes. Users can easily adjust and fix the height by simply adjusting the locking bolts, making the operation convenient and time-saving.

[0012] In some embodiments of this application, the outer tube has a threaded hole, the locking bolt is installed in the threaded hole, one end of the locking bolt extends into the outer tube and abuts against the outer surface of the inner rod, and rotating the locking bolt locks or unlocks the locking bolt and the inner rod.

[0013] In some embodiments of this application, the telescopic bracket further includes a spring, one end of which is connected to the outer tube and the other end of which is connected to the inner rod. The spring applies an upward force to the inner rod, and when the locking bolt is in the unlocked state, the inner rod moves upward under the action of the spring.

[0014] The spring design allows the inner rod to move automatically upwards in the unlocked state, eliminating the need for manual pulling and making operation more convenient. When height adjustment is required, the user simply needs to unlock the bolt, and the spring will automatically raise the inner rod to the preset height, simplifying the adjustment process.

[0015] The upward force provided by the spring can offset the weight of the camera to some extent, reducing the burden on the locking bolts and improving the overall structural stability. When the locking bolts are unlocked, the spring prevents the inner rod from accidentally sliding down, ensuring the camera's safety during display.

[0016] In some embodiments of this application, the host includes a base and a base holder connected by an anti-theft cable. The base holder rests on the base and is magnetically connected to the base. The base is mounted on a display stand, and the camera body is connected to the base holder.

[0017] This application utilizes a base and holder connected by an anti-theft cable. The base is mounted on a display stand, and the camera body is connected to the holder, allowing the camera to be detached from the display stand and picked up for viewing and handling. Furthermore, the magnetic connection makes placing the camera body extremely simple; the user merely needs to approach the connection point, and the magnet will automatically attract it, making it convenient and quick. At the same time, the magnetic connection also provides a strong hold, ensuring the camera body will not easily detach during use, enhancing product security.

[0018] In some embodiments of this application, the base is provided with a locking device, which extends out of the base and connects to the camera body; the base is connected to a first alarm device via an anti-theft wire, and the first alarm device is adapted to an optical lens mounted on the camera body.

[0019] To fully showcase the digital camera's functionality, various optical lenses will be provided with the camera body, including a main lens that is connected to the camera body and replaceable lenses that can be placed on a display stand. When a customer picks up and handles the camera body, the main lens will obviously be picked up along with it. Therefore, this application incorporates a first alarm component connected to the base via an anti-theft cable to accommodate this usage scenario. Furthermore, the anti-theft cable also accommodates situations where the customer wishes to detach the main lens for separate inspection.

[0020] In some embodiments of this application, the first alarm component includes an arc-shaped connector and a mounting housing protruding from the back of the arc-shaped connector. A circuit board is disposed inside the mounting housing. A third sensor electrically connected to the circuit board is disposed in the middle of the arc-shaped connector. The third sensor is in contact with and connected to an optical lens. An indicator light is disposed on the mounting housing and is connected to the circuit board.

[0021] The curved connector design allows it to fit snugly against the outer circumference of the optical lens, ensuring good contact between the sensor and the lens, thus improving the sensitivity and reliability of the alarm system. The indicator lights provide intuitive status feedback, allowing users to quickly understand the alarm system's operating status by observing their on / off state, enhancing the user experience. The third sensor can monitor the optical lens's status in real time; in the event of an anomaly (such as lens removal), it can quickly trigger an alarm, enhancing the timeliness of anti-theft protection.

[0022] Secured via an adhesive layer, the curved connectors allow for quick and easy installation and removal, reducing reliance on tools and enhancing the user experience. This design avoids the use of screws or other mechanical fasteners, maintaining a clean and aesthetically pleasing overall appearance and improving the product's visual appeal.

[0023] In some embodiments of this application, the arc-shaped connector matches the outer peripheral surface of the optical lens, and adhesive layers are provided at both ends of the inner wall of the arc-shaped connector. The arc-shaped connector is fixedly connected to the optical lens through the adhesive layers.

[0024] In some embodiments of this application, the base has multiple connection ports on its side. The connection ports are matched with anti-theft wires, and the end of the anti-theft wire is inserted into the connection port to be electrically connected to the control device in the host.

[0025] This application features multiple connection ports for the installation of multiple anti-theft cables. These cables are connected to an alarm device, enabling simultaneous anti-theft protection for multiple optical lenses.

[0026] The anti-theft wire is made of spring wire; the first, second, and third sensors are all push-button sensors.

[0027] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

[0037] The present application will now be described in detail with reference to the accompanying drawings.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0039] Digital camera anti-theft alarm, Example 1 as follows Figures 1 to 3 As shown, the device includes a main unit 1, a telescopic bracket 2, and at least one alarm component 3. The main unit 1 and the telescopic bracket 2 are respectively mounted on the display stand. The main unit 1 contains a control device. The alarm component 3 is connected to the main unit 1 via an anti-theft line 9. Each alarm corresponds to one optical lens 6, and the alarm component 3 is connected to the optical lens 6. The alarm system of this application integrates the anti-theft protection of the camera body 5 and the optical lens 6 into one system, avoiding the cumbersome process of setting up each optical lens 6 separately in traditional anti-theft devices, and reducing the complexity and cost of the equipment.

[0040] The camera body 5 is mounted on the main unit 1, and the optical lens 6 connected to the camera body 5 is mounted on top of the telescopic bracket 2. By using the telescopic bracket 2, the connected optical lens 6 can be displayed in conjunction with the camera body 5 during demonstrations. The telescopic bracket 2 can be adjusted as needed to accommodate different models and sizes of camera lenses, thus enhancing the product's applicability. Displaying the connected camera body 5 and optical lens 6 provides better aesthetics and visibility, ensuring users can clearly see the product's appearance and functions, thereby improving the demonstration effect.

[0041] The main unit 1 is equipped with a first sensor 7 and a second sensor 8, which are respectively connected to the control device. The first sensor 7 extends out of the upper surface of the main unit 1 and contacts the camera body 5. The second sensor 8 extends out of the lower surface of the main unit 1 and contacts the display table surface. By setting the first sensor 7 and the second sensor 8, the connection status between the camera body 5 and the display table surface can be monitored in real time. Once an abnormality occurs (such as the camera being removed), the control device inside the main unit 1 will provide anti-theft protection (such as issuing an alarm).

[0042] This application is equipped with at least one alarm device 3, and the alarm device and the optical lens 6 are connected to each other in a one-to-one correspondence. Therefore, this application can not only protect the camera body 5, but also protect multiple optical lenses 6 at the same time, meet the display needs of multiple optical lenses 6 of digital cameras, and improve the overall anti-theft capability of the product.

[0043] Example 2, as Figures 1 to 5As shown, both the bottom of the telescopic bracket 2 and the bottom of the main unit 1 are provided with adhesive layers, which are then fixedly connected to the display table surface. The telescopic bracket 2 is positioned in front of the main unit 1. To fully demonstrate the functions of the digital camera, various optical lenses 6 will be matched to the camera body 5, including the main lens connected to the camera body 5. Therefore, the telescopic bracket 2 in this application is mainly for supporting the main lens, making the placement of the entire digital camera more stable and reliable.

[0044] The telescopic bracket 2, from top to bottom, includes a bracket 10, an inner rod 11, an outer tube 12, and a base 13. The bracket 10 is connected to the top surface of the inner rod 11, and the outer tube 12 is fitted over the inner rod 11 and connected to the base. The inner rod 11 and the outer tube 12 are coaxially arranged, and the inner rod 11 can move up and down relative to the outer tube 12 under force. A locking bolt 14 is installed on the outer tube 12, and the locking bolt 14 abuts against the surface of the inner rod 11. Adjusting the locking bolt 14 allows the inner rod 11 to be fixed or movable relative to the outer tube 12. This design allows the inner rod 11 to move up and down within the outer tube 12, so that the height of the bracket can be adjusted as needed to accommodate different models and sizes of camera lenses. Users only need to simply adjust the locking bolt 14 to adjust and fix the height, which is convenient and saves time.

[0045] The outer tube 12 has a threaded hole, and the locking bolt 14 is installed in the threaded hole. One end of the locking bolt 14 extends into the outer tube 12 and abuts against the outer surface of the inner rod 11. Rotating the locking bolt 14 locks or unlocks the locking bolt 14 and the inner rod 11. The telescopic bracket 2 also includes a spring 16. One end of the spring 16 is connected to the outer tube 12, and the other end of the spring 16 is connected to the inner rod 11. The spring 16 applies an upward force to the inner rod 11. When the locking bolt 14 is in the unlocked state, the inner rod 11 moves upward under the action of the spring 16.

[0046] The design of spring 16 allows the inner rod 11 to move automatically upwards in the unlocked state, eliminating the need for manual pulling and making operation more convenient. When height adjustment is required, the user simply needs to unlock the bolt, and the spring 16 will automatically raise the inner rod 11 to the preset height, simplifying the adjustment process.

[0047] The upward force provided by spring 16 can offset the weight of the camera to some extent, reducing the burden on locking bolt 14 and improving the stability of the overall structure. When locking bolt 14 is unlocked, the function of spring 16 can prevent the inner rod 11 from accidentally sliding down, ensuring the safety of the camera during display.

[0048] The rest of the contents of Example 2 are the same as those of Example 1.

[0049] Example 3, as Figures 4 to 7As shown, the host 1 includes a base 17 and a base 18 connected by an anti-theft cable 9. The base 18 is placed on the base 17 and is magnetically connected to the base 17. The base 17 is installed on the display table surface, and the camera body 5 is connected to the base 18.

[0050] This application utilizes an anti-theft cable 9 to connect the base 17 and the base holder 18. The base 17 is mounted on the display stand, and the camera body 5 is connected to the base holder 18. This allows the camera to be detached from the display stand and picked up for viewing and handling. Furthermore, the magnetic connection makes placing the camera body 5 extremely simple; the user only needs to approach the connection point, and the magnet will automatically attract it, making it convenient and quick. At the same time, the magnetic connection also provides a good fixing effect, ensuring that the camera body 5 will not easily fall off during use, enhancing product security.

[0051] The base 18 is equipped with a locking fastener 19, which extends out of the base 18 and connects to the camera body 5. The base 18 is connected to a first alarm element 3 via an anti-theft cable 9. The first alarm element 3 is compatible with the optical lens 6 mounted on the camera body 5. To fully demonstrate the functions of the digital camera, various optical lenses 6 are matched to the camera body 5, including the main lens connected to the camera body 5 and replaceable lenses placed on the display table. When a customer picks up and handles the camera body, the main lens is obviously picked up along with the camera body 5. Therefore, the first alarm element 3 is connected to the base 18 via the anti-theft cable 9 to accommodate this usage scenario. Furthermore, the anti-theft cable 9 also accommodates situations where the customer wants to disassemble and examine the main lens separately.

[0052] The first alarm component 3 includes an arc-shaped connector 20 and a mounting housing 21 protruding from the back of the arc-shaped connector 20. A circuit board is provided inside the mounting housing 21. A third sensor 22 electrically connected to the circuit board is provided in the middle of the arc-shaped connector 20. The third sensor 22 is in contact with the optical lens 6. An indicator light 23 is provided on the mounting housing 21. The indicator light 23 is connected to the circuit board.

[0053] The arc-shaped connector 20 is designed to fit snugly against the outer periphery of the optical lens 6, ensuring good contact between the sensor and the lens and improving the sensitivity and reliability of the alarm system. The indicator light 23 provides intuitive status feedback, allowing users to quickly understand the alarm system's operating status by monitoring its on / off state, enhancing the user experience. The third sensor 22 can monitor the status of the optical lens 6 in real time; in the event of an anomaly (such as lens removal), it can quickly trigger an alarm, enhancing the timeliness of anti-theft protection. The adhesive layer allows users to quickly and easily install and remove the arc-shaped connector 20, reducing reliance on tools and improving the user experience. This design avoids the use of screws or other mechanical fasteners, maintaining a clean and aesthetically pleasing overall appearance and enhancing the product's visual appeal.

[0054] The arc-shaped connector 20 matches the outer peripheral surface of the optical lens 6. Adhesive layers are provided at both ends of the inner wall of the arc-shaped connector 20, and the arc-shaped connector 20 is fixedly connected to the optical lens 6 through the adhesive layers.

[0055] The base 17 has multiple connection ports 24 on its side. Each connection port 24 is matched with an anti-theft cable 9. When the end of the anti-theft cable 9 is inserted into the connection port 24, it is electrically connected to the control device inside the host 1. This application provides multiple connection ports 24 to cooperate with multiple anti-theft cables 9. The anti-theft cable 9 is connected to the alarm device 3, which can simultaneously provide anti-theft protection for multiple optical lenses 6.

[0056] The anti-theft line 9 uses a spring-loaded 16-wire; the first sensing element 7, the second sensing element 8, and the third sensing element 22 all use push-button sensing elements.

[0057] The other contents of Example 3 are the same as those of Example 1 or Example 2.
