Many specific details are set forth in the following description to provide a full understanding of this utility model.

Therefore, this utility model is not limited to the specific embodiments disclosed below.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1 and Figure 2 As shown,

[0025] As an alternative embodiment,

[0026] A smart meter that is easy to wire includes a meter box 1, in which at least one meter is installed. A wire inlet plate 2 is installed on the bottom of the meter box 1. The wire inlet plate 2 has at least two wire inlet holes 21. A wire clamping structure 3 for clamping multiple wires inserted into the wire inlet holes 21 is installed horizontally in the meter box 1. The wire clamping structure 3 includes a frame 36. A wire clamping base plate 37 is fixedly connected inside the frame 36. A wire clamping top block 34 that cooperates with the wire clamping base plate 37 is installed inside the frame 36. The wire clamping top block 34 is slidably connected to the frame 36. A flat push component for driving the wire clamping top block 34 toward the wire clamping base plate 37 is installed on the frame 36.

[0027] Specifically, multiple meters are installed in the meter box 1, and the L and N lines are connected to the meter terminals after passing through the corresponding two inlet holes 21. To prevent the power lines connected to the terminals from coming loose, a clamping structure 3 is designed to clamp the multiple power lines passing through the inlet holes 21. The frame 36 is inserted horizontally from the side of the meter box 1, and the flat pushing component uses the frame 36 as support to push the clamping top block 34 toward the clamping bottom plate 37. As the distance between the clamping top block 34 and the clamping bottom plate 37 decreases, the power lines are clamped and fixed, thereby preventing the power lines connected to the terminals from coming loose.

[0028] Based on the previous embodiment, further improvements are made. As shown in the figure, the flat push assembly includes a screw 31. Both ends of the screw 31 are connected to the side of the frame 36 through bearing seats. A first slider 32a and a second slider 32b are sleeved on the screw 31. A first connecting rod 33a and a second connecting rod 33b are provided between the screw 31 and the clamping top block 34. The first connecting rod 33a and the second connecting rod 33b are distributed in a V-shape. One end of the first connecting rod 33a is hinged to the clamping top block 34, and the other end of the first connecting rod 33a is hinged to the second slider 32b. One end of the second connecting rod 33b is hinged to the clamping top block 34, and the other end of the second connecting rod 33b is hinged to the first slider 32a.

[0029] The drive screw 31 can rotate on the frame 36, thereby moving the first slider 32a and the second slider 32b away from each other. As the first slider 32a and the second slider 32b move away from each other, the first connecting rod 33a and the second connecting rod 33b gradually change from an inclined state to a vertical state, thereby pushing the wire clamping top block 34 closer to the wire clamping bottom plate 37. The screw 31 is threaded with the two sliders, which can be stopped at any time. The force of clamping the wire can be controlled by rotating the screw 31, thereby ensuring that the clamping force for wires of different diameters is adjustable.

[0030] The frame 36 has sliding grooves 35 installed on the opposite side walls inside, and the wire clamping top block 34 is slidably connected in the sliding grooves 35. The sliding grooves 35 can constrain the movement trajectory of the wire clamping top block 34.

[0031] Specifically, as shown in the figure, a support component 38 is provided between the wire clamping top block 34 and the wire clamping bottom plate 37. The support component 38 includes a first support block 381, a second support block 383, and a telescopic component 382. One end of the telescopic component 382 is connected to the first support block 381, and the other end of the telescopic component 382 is connected to the second support block 383. Both ends of the first support block 381 and the second support block 383 are slidably connected in the slide groove 35. The support component 38 is located between the wire clamping top block 34 and the wire clamping bottom plate 37 and is used to adjust and accommodate the clamping of multiple wires. It can ensure the clamping and fixing of multiple wires. The first support block 381 cooperates with the wire clamping top block 34 to clamp the wire on the right side, while the second support block 383 cooperates with the wire clamping bottom plate 37 to clamp the wire on the left side. The telescopic component 382 can adjust the distance between the first support block 381 and the second support block 383, thereby better adapting to the clamping and fixing of wires.

[0032] Regarding the telescopic component 382, ​​an electric telescopic rod can be selected. However, in this embodiment, a specific telescopic component 382 is designed. This telescopic component 382 includes a first connecting rod 382a, an internally threaded sleeve 382b, and a second connecting rod 382c. One end of the first connecting rod 382a is hinged to the first support block 381, and one end of the second connecting rod 382c is hinged to the second support block 383. One end of the internally threaded sleeve 382b is connected to the first connecting rod 382a via a bearing. The other end of 2b is fitted onto the second connecting rod 382c, which is threadedly connected to the internal threaded sleeve 382b. Subsequently, by rotating the internal threaded sleeve 382b, the second connecting rod 382c moves in and out of it, thereby changing the overall length of the telescopic component 382. The internal threaded sleeve 382b is supported by the first connecting rod 382a and rotates at its end. A bearing is connected between the two, thereby constraining the internal threaded sleeve 382b to rotate on the first connecting rod 382a while maintaining its connection with it.

[0033] The top clamping block 34, the bottom clamping plate 37, the first support block 381 and the second support block 383 are all provided with wire-binding grooves 39, which are used to accommodate and limit the forward and backward displacement of the wires after they pass through.

[0034] A knob 6 for driving the screw 31 to rotate is installed on the side of the meter box 1. The knob 6 passes through the side wall of the meter box 1 and is connected to the screw 31. The wire can be tightened by rotating the knob 6 on the surface of the meter box 1.

[0035] The meter box 1 is equipped with an observation window 5 for the internal meter. The observation window 5 is made of transparent material, such as glass or transparent plastic plate, so that the internal situation can be observed or the information displayed by the internal meter can be read.

[0036] The meter box 1 is equipped with an openable door 4, which is connected to the meter box 1 by a hinge so that the wires inserted through the inlet hole 21 can be connected to the terminals of the meter after the meter box 1 is opened.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
