Abstract
Description
Technical Field
[0001] This utility model relates to the field of cargo security alarm technology, and in particular to a container cargo security alarm device. Background Technology
[0002] With the rapid development of global trade, container shipping has become the core mode of cross-border circulation of goods. However, during the transportation and transshipment of containers on trucks, they frequently face security risks such as theft, illegal opening, or violent hijacking. Traditional security measures mainly rely on mechanical locks to lock the container doors.
[0003] However, mechanical locks can only provide physical barriers and cannot protect against illegal acts such as cutting and prying, and they lack real-time alarm functions, which can lead to the theft of goods.
[0004] Therefore, it is necessary to design a container cargo security alarm device. Utility Model Content
[0005] In order to overcome the shortcoming that truck container locks cannot provide real-time alarms when they are violently damaged, the purpose of this utility model is to provide a container cargo security alarm device.
[0006] The technical solution is as follows: A container cargo security alarm device includes a container body, a container door, a mounting frame, a strong magnet, a pressure sensor, a compression spring, a control panel, and an alarm. The container body has rotating container doors on both the left and right sides of the opening. Two mounting frames are provided, and the device is installed through these frames. A strong magnet is fixedly installed inside the mounting frame. The strong magnet has strong magnetism. A pressure sensor is slidably installed in the middle of the strong magnet. A compression spring is fixedly connected between the front end of the pressure sensor and the inner end face of the mounting frame. A control panel is fixedly installed on the front end face of the mounting frame, and an alarm is fixedly installed on the front end face of the control panel. The device is magnetically installed on the upper, middle, and lower parts of the container door using the strong magnet, and is located on the side where the container door is close to each other when it is open.
[0007] As an improvement to the above solution, it also includes a U-shaped handle and a torsion spring. Torsion springs are fixed to the middle of both sides of the mounting frame, and a U-shaped handle is fixed to the other end of the two torsion springs. In the initial state, the U-shaped handle is located below the mounting frame.
[0008] As an improvement to the above solution, it also includes a U-shaped connecting plate, a locking block, and a telescopic spring. The U-shaped connecting plate is fixed to the upper end of the mounting frame, with its U-shaped opening facing upwards. A notch is opened in the middle of the side of the U-shaped connecting plate away from the U-shaped surface. Several telescopic springs are fixed to the bottom surface of each notch, and a locking block is fixed to the other end of each telescopic spring.
[0009] As an improvement to the above solution, it also includes buckles. Buckles are fixed to both the front and rear sides of the middle of the lower end face of the mounting frame, and the two mounting frames can be connected by buckles and clips.
[0010] As an improvement to the above solution, when the two mounting frames are snapped together, the U-shaped handle of the upper mounting frame snaps into the U-shaped connecting plate on the lower mounting frame.
[0011] As an improvement to the above solution, the bottom surface of the buckle is an upward-sloping guide slope, which facilitates engagement with the buckle block.
[0012] This invention has the following advantages: It uses a strong magnet to forcefully attach to the container door. When the pressure sensor is subjected to damaging pressure, it sends a signal to the control panel, which then controls the alarm to sound. This achieves the effect of promptly alerting the truck personnel when the truck container is violently damaged. Attached Figure Description

Detailed Implementation
[0019] Example: A container cargo security alarm device, such as Figures 1-5As shown, the device includes a container body 1, a container door 2, a mounting frame 3, a strong magnet 4, a pressure sensor 5, a compression spring 6, a control panel 7, and an alarm 8. The container body 1 has rotating container doors 2 on both the left and right sides of the opening. Two mounting frames 3 are provided, and the device is installed through these frames. A strong magnet 4 is fixedly installed inside the mounting frame 3. The strong magnet 4 has strong magnetism. A pressure sensor 5 is slidably installed in the middle of the strong magnet 4. A compression spring 6 is fixedly connected between the front end of the pressure sensor 5 and the inner end face of the mounting frame 3. A control panel 7 is fixedly installed on the front end of the mounting frame 3, and an alarm 8 is fixedly installed on the front end of the control panel 7. The device is magnetically installed on the upper, middle, and lower parts of the container door 2 by the strong magnet 4, and is located on the side where the container door 2 is close to each other when it is open.
[0020] like Figure 2 As shown, it also includes a U-shaped handle 9 and a torsion spring 10. Torsion springs 10 are fixedly connected to the middle of both sides of the mounting frame 3. A U-shaped handle 9 is fixedly connected to the other end of the two torsion springs 10. In the initial state, the U-shaped handle 9 is located below the mounting frame 3.
[0021] like Figure 2 and Figure 5 As shown, it also includes a U-shaped connecting plate 11, a locking block 13 and a telescopic spring 14. The U-shaped connecting plate 11 is fixed to the upper end face of the mounting frame 3, with its U-shaped opening facing upward. A notch is opened in the middle of the side of the U-shaped connecting plate 11 away from the U-shaped surface. Several telescopic springs 14 are fixed to the bottom surface of the notch. A locking block 13 is fixed to the other end of each telescopic spring 14.
[0022] like Figure 2 and Figure 5 As shown, it also includes a buckle 12. Buckles 12 are fixed to the front and rear sides of the middle of the lower end face of the mounting frame 3. The two mounting frames 3 can be connected by buckles 12 and locking blocks 13. When the two mounting frames 3 are connected, the U-shaped handle 9 of the upper mounting frame 3 is inserted into the U-shaped connecting plate 11 on the lower mounting frame 3. The bottom surface of the buckle 12 is an upwardly inclined guide slope, which facilitates the connection with the locking block 13.
[0023] The device is magnetically installed on the side of the container door 2 that is close to each other when it is opened, using a strong magnet 4 within the mounting frame 3. The pressure sensor 5 is pressed tightly against the container door 2 by the compression force of the compression spring 6. When the container door 2 is violently damaged, the pressure sensor 5 is forced to compress the compression spring 6, simultaneously transmitting the pressure to the control panel 7. Upon receiving the pressure signal, the control panel 7 activates the alarm 8 to sound an alarm for the truck's hijacking system, alerting the truck occupants. When multiple hijacking devices need to be connected together, first pull the U-shaped handle 9 of the device to be removed. The torsion spring 10 deforms, pulling the strong magnet 4 from the container door. Remove the U-shaped handle 9 from the door 2 and release it. The torsion spring 10 will cause the U-shaped handle 9 to return to its original position. Then, the removed U-shaped connecting plate 11 will be inserted between the latches 12 of the hijacking device that needs to be inserted. During this process, the latch 13 on the U-shaped connecting plate 11 will contact the latch 12. The inclined surface of the latch 12 will press the latch 13 to retract it into the U-shaped connecting plate 11. The telescopic spring 14 will be compressed. When the U-shaped connecting plate 11 slides into the top of the latch 12, the latch 13 will pop out under the action of the telescopic spring 14, so that the two mounting frames 3 are inserted. At the same time, the U-shaped handle 9 of the hijacking device that needs to be inserted will be inserted into the U-shaped connecting plate 11 of the removed hijacking device.
