[0029] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0030] Please see Figure 1-8 This utility model provides a technical solution:

[0031] A smart meter with anti-theft security packaging includes a display controller 1 and a meter assembly 2. A protection component 3 is rotatably connected to the inside of the meter assembly 2, and a locking component 4 is slidably connected to the inside of the meter assembly 2. The meter assembly 2 includes a meter body 21, a wire groove 22 on the inside of the meter body 21, a terminal block 23 installed on the inside of the meter body 21, a wire through hole 24 on the inside of the lower end of the meter body 21, a first spring groove 25 on the inside of the meter body 21, a spring 26 fixedly connected to the inside of the first spring groove 25, and a pressure spring 26 fixedly connected to the rear end of the wire groove 22 on the meter body 21. The meter body 21 has a force sensor 27, a second spring groove 28 on its inner side, a protective assembly 3 including a protective plate 31, a handle 32 fixedly connected to the front end of the protective plate 31, a rectangular slot 33 on its inner side, a shaft column 34 fixedly connected to the upper end of the protective plate 31, a rubber column 35 fixedly connected to the rear end of the protective plate 31, a locking assembly 4 including a ramp rod 41, a limit slider 42 fixedly connected to the top end of the ramp rod 41, a first electromagnet 43 fixedly connected to the inner side of the ramp rod 41, a linear spring 44 fixedly connected to the right side of the ramp rod 41, and a second electromagnet 45 fixedly connected to the right end of the wire groove 22 on the meter body 21.

[0032] As a further implementation of this solution, the wire trough 22 passes through the front end of the meter body 21, and the wire trough 22 is connected to the wire through hole 24. The wire through hole 24 passes through the lower end of the meter body 21. Through the connection design of the wire trough 22 and the wire through hole 24, the external wiring of the meter can be simplified.

[0033] As a further implementation of this solution, the wire groove 22 is connected to the first spring groove 25. The first spring groove 25 is shaped like two cylindrical sections. There are two first spring grooves 25. The display controller 1 is equipped with a controller. The pressure sensor 27 is electrically connected to the controller of the display controller 1. The second electromagnet 45 and the first electromagnet 43 are electrically connected to the controller of the display controller 1. The controller can receive commands from a remote computer to detect the open / closed state of the protective plate 31, and at the same time, it is convenient to control the action of the first electromagnet 43 and the second electromagnet 45.

[0034] As a further implementation of this solution, the inner side of the spring 26 is fixedly connected to the outer side of the shaft 34. The shaft 34 is cylindrical in shape, and there are two shafts 34. The shafts 34 are fixedly connected to the left and right sides of the protective plate 31. The shafts 34 are rotatably connected to the inner side of the first spring groove 25 opened in the meter body 21. The fixed connection between the spring 26 and the shaft 34 ensures the stability of the rotating parts.

[0035] As a further implementation of this solution, the rectangular slot 33 is rectangular in shape and passes through one end of the protective plate 31. There are two rectangular slots 33, which are located at the left and right ends of the protective plate 31. The ramp rod 41 is engaged inside the rectangular slot 33. The rear end of the rubber column 35 is attached to the front end of the pressure sensor 27, so that when the protective plate 31 is closed, the ramp rod 41 is passively engaged inside the rectangular slot 33, thereby achieving the effect of locking the protective plate 31 and preventing users from illegally tampering with the meter wiring to steal electricity.

[0036] As a further implementation of this solution, the second spring groove 28 is formed by a combination of a cylinder and a rectangle. There are two second spring grooves 28. The second spring groove 28 is connected to the wire groove 22. The slope clamp 41 is slidably connected to the inside of the second spring groove 28 through the limiting slider 42, which serves to limit the movement of the slope clamp 41 and prevent the slope clamp 41 from twisting inside the second spring groove 28.

[0037] As a further implementation of this solution, the limiting slider 42 is rectangular in shape, the left end of the ramp rod 41 is sloping, the right side of the second electromagnet 45 is fixedly connected to one side of the second spring groove 28 opened in the meter body 21, the second electromagnet 45 and the first electromagnet 43 are on the same horizontal line, and one side of the linear spring 44 is fixedly connected to one side of the second spring groove 28 opened in the meter body 21. No special parts are needed to maintain the meter. This opening method does not require operating physical tools, thus not only preventing illegal tampering with the meter wiring to steal electricity, but also improving the security of the meter.

[0038] Workflow: To prevent users from illegally tampering with the meter wiring to steal electricity, firstly, the external wiring is passed through the wire through hole 24. Then, the meter wiring is connected to the corresponding terminals 23. After connection, the protective plate 31 is released. Under the elastic torque of the spring 26, the shaft 34 rotates. The shaft 34 is rotatably connected to the inner side of the first spring groove 25. The rotation of the shaft 34 drives the protective plate 31 to rotate. The protective plate 31 rotates rapidly. Under the action of inertia and the torque of the spring 26, the protective plate 31 presses against the ramp 41. The ramp 41, under the action of pressing... The lever 41 slides inside the second spring groove 28 via the limiting slider 42. The limiting slider 42 limits the sliding direction of the lever 41, preventing it from twisting inside the second spring groove 28. The lever 41 compresses the linear spring 44, causing it to elastically deform. The torque of the two spring springs 26 is greater than the elastic force of the two linear springs 44. When the lever 41 aligns with the rectangular groove 33, the linear spring 44 pushes the lever 41 to slide into the rectangular groove 33. Based on the sloped structure of the lever 41, the protective plate 31... The ramp lever 41 can be pushed, but once the ramp lever 41 is inside the rectangular slot 33, the protective plate 31 cannot be pulled. Simultaneously, when the protective plate 31 moves, it moves the rubber column 35. The rubber column 35 contacts the pressure sensor 27. When the pressure sensor 27 senses pressure, the indicator light on the display controller 1 flashes, indicating that the protective plate 31 is locked. The rubber column 35 also acts as a buffer when the protective plate 31 rotates. Opening the protective plate 31 requires permission from specific personnel and the controller. The controller inside the display controller 1 connects to the specific personnel's computer. In the Internet of Things (IoT) system, the second electromagnet 45 and the first electromagnet 43 can only be energized by specific personnel. After the first electromagnet 43 and the second electromagnet 45 are energized, the first electromagnet 43 and the second electromagnet 45 are magnetically attracted. Under the action of magnetic attraction, the first electromagnet 43 will drive the ramp 41 to be stored inside the second spring groove 28. The protective plate 31 can be opened by pulling the handle 32. The device does not require the use of specific parts to maintain the electricity meter. This opening method does not involve operating physical tools, thus not only preventing illegal tampering with the electricity meter wiring to steal electricity, but also improving the security of the electricity meter.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
