[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figures 1 to 3The utility model provides a technical solution: a guide rail electric energy meter, comprising an electric energy meter body 1, a slot 2 connected to the guide rail and a plug plate 4 installed at the lower end of the back of the electric energy meter body 1 and capable of sliding up and down, the plug plate 4 can clamp the guide rail, two fixing seats 12 are installed at the bottom of the electric energy meter body 1, the two fixing seats 12 are concentric, a connecting rod 11 is rotatably connected to the middle of the fixing seat 12, a turntable 10 is fixedly connected to one end of the connecting rod 11, a push column 9 is fixedly connected to the top of the turntable 10 near the connecting rod 11, and the turntable 10 can drive the push column 9 to rotate around the connecting rod 11. The rod 11 rotates, and a slide groove 3 is opened inside the back of the electric energy meter body 1. A fixed plate 7 is fixedly connected to the inner wall of the slide groove 3. The fixed plate 7 is fixed to the slide groove 3 on three sides. The plug plate 4 slides inside the slide groove 3, and a movable plate 5 is fixedly connected inside the plug plate 4. The movable plate 5 is located above one side close to the fixed plate 7 inside the slide groove 3. A return spring 6 is installed between the movable plate 5 and the fixed plate 7. There are two return springs 6 symmetrically arranged between the movable plate 5 and the fixed plate 7. A guide groove 8 is opened inside the plug plate 4. The guide groove 8 is a horizontally arranged rectangular groove, and the push column 9 is slidably connected to the guide groove 8.

[0017] Among them, the end of the connecting rod 11 away from the plug board 4 is fixedly connected with a swing arm 13, and the swing arm 13 corresponds to the position of the turntable 10. The rotation of the turntable 10 will be synchronized with the swing arm 13, so that the rotation position of the turntable 10 can be known.

[0018] The plug plate 4 slides with the fixed plate 7 away from the side of the electric energy meter body 1 , and the plug plate 4 fits the fixed plate 7 and will not shake when moving up and down.

[0019] When the push post 9 slides to the left end of the guide groove 8, the insert plate 4 can be completely retracted into the inside of the slide groove 3, and the push post 9 slides to the left end of the guide groove 8 driven by the turntable 10, and the insert plate 4 moves downward.

[0020] The end of the push post 9 extending into the guide groove 8 does not exceed the groove depth of the guide groove 8 , and the push post 9 will not extend into the slide groove 3 , thereby preventing the push post 9 from colliding with the fixing plate 7 .

[0021] Specifically, when installing the electric energy meter body 1, the swing arm 13 can be rotated first so that the connecting rod 11 drives the turntable 10 to rotate, and then the push column 9 will slide to the left end inside the guide groove 8, so that the plug plate 4 pushes the movable plate 5 downward to squeeze the reset spring 6, the plug plate 4 will shrink to the inside of the slide groove 3, and then the slot 2 is clamped on the guide rail and the swing arm 13 is released. The movable plate 5 drives the plug plate 4 to reset and clamp the guide rail under the push of the reset spring 6.
