[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figures 1 to 5 The illustrated multi-functional energy meter includes a meter body 1 and a cover 2 for covering the terminal wiring area. In this embodiment, the terminal wiring area is located at the bottom front end of the meter body 1 and is an open area. The cover 2 is a conformal cover, used to maintain the overall shape of the meter body 1, and the cover 2 matches the terminal wiring area.

[0019] Two mounting slots are provided on the meter body 1, extending from the rear end to the front end of the meter body 1. The rear end of each mounting slot is closed, while the front end of each mounting slot is open. The two mounting slots are symmetrically arranged, one on the left and one on the right, relative to the terminal wiring area.

[0020] Specifically, the mounting groove includes a limiting groove 4 and a guide groove 3, which are connected. The front and rear ends of the limiting groove 4 are closed, and the rear end of the guide groove 3 is closed while the front end is open. The guide groove 3 is located on the side of the limiting groove 4 and is connected to the opposite side. The side of the guide groove 3 away from the limiting groove 4 is connected to the outside of the meter body 1, and the guide groove 3 is also connected to the terminal wiring area.

[0021] Each mounting slot has a slidable pull rod.

[0022] Specifically, the pull rod includes a cross-shaped slider 5 and a rectangular block 6, which are fixedly connected. The limiting groove 4 is a groove with a cross-shaped cross section, and the cross-shaped slider 5 matches and slides with the limiting groove 4. The guide groove 3 is a groove with a rectangular cross section, and the rectangular block 6 matches and slides with the guide groove 3.

[0023] The cover 2 is rotatably connected to two pull rods. In this embodiment, the cover 2 rotates along the vertical plane.

[0024] Specifically, two rotation clearance grooves are provided at the top end of the corresponding terminal wiring area on the cover 2, and the two rotation clearance grooves correspond one-to-one with the two pull rods. A mounting base is fixedly installed at the front end of the rectangular block 6 of each of the two pull rods, and each mounting base is inserted into the rotation clearance groove corresponding to its pull rod and slides with the cover 2.

[0025] Each mounting base is fixed with a horizontal support shaft 7. The two support shafts 7 are coaxially opposed, and the two axial ends of the two support shafts 7 correspond to the left and right ends of the watch body 1, respectively. The two axial ends of each support shaft 7 are inserted into the cover 2, and the cover 2 is rotatably connected to the two support shafts 7.

[0026] Each support shaft 7 is fitted with a torsion spring. One end of each torsion spring is fixedly connected to the mounting base where the support shaft 7 is located, and the other end of each torsion spring is fixedly connected to the cover 2.

[0027] A first magnetic stripe 8 is fixedly installed on the bottom end face of the corresponding terminal wiring area on the body 1, and a second magnetic stripe 9 is fixedly installed on the bottom end face of the corresponding terminal wiring area on the cover 2. The first magnetic stripe 8 and the second magnetic stripe 9 are magnetically attracted to each other.

[0028] It should be noted that all directions involved in this embodiment are based on Table 1.

[0029] Working principle: When it is necessary to open the cover 2 to connect wires in the terminal wiring area of ​​this multi-functional energy meter, pull the cover 2 to move it away from the meter body 1. The cover 2 drives the two mounting seats to move away from the meter body 1 via two support shafts 7. The two mounting seats pull the lever to slide out of their respective mounting slots. During this process, the top end face of the cover 2 slides against the meter body 1 above it under the elastic force of the torsion spring.

[0030] As the cover 2 continues to move, it detaches from the watch body 1 above it. At this point, under the force of the torsion spring, the cover 2 flips upward 90 degrees and finally comes into contact with the watch body 1. Afterward, the wiring can be completed.

[0031] After wiring is complete, push the cover 2 to rotate it downwards by 90 degrees. During this process, the torsion spring is twisted. Next, push the cover 2 towards the watch body 1. The cover 2 moves closer to the watch body 1 and gradually covers the terminal wiring area. When the cover 2 contacts the watch body 1, the first magnetic strip 8 and the second magnetic strip 9 are attracted.

[0032] To prevent the terminal wiring area from being opened due to accidental contact, a spring can be installed in the guide groove 3, with the spring positioned along the sliding direction of the rectangular block 6. One end of the spring is fixedly connected to the watch body 1, and the other end is fixedly connected to the rectangular block 6. Initially, the spring is in a stretched state, and the cover 2 is in contact with the watch body 1.

[0033] To prevent unauthorized wiring and electricity theft, a lead seal can be installed between the meter body 1 and the cover 2 after the first magnetic strip 8 and the second magnetic strip 9 are attracted together.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
