Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The following will further describe the present application in detail in conjunction with the attached Figure 1 —5,

[0027] The embodiment of the present application discloses an electricity meter with a connection wire limiting structure. Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , an electricity meter with a connection wire limiting structure includes an electricity meter body 1. A limiting device 2 is provided on one side of the electricity meter body 1. The limiting device 2 includes a housing 3 fixed on one side of the electricity meter body 1. The housing 3 has a wire slot 301, and a pair of assembly grooves 302 are provided in the wire slot 301.

[0028] A screw 4 is installed through the top of the housing 3. The bottom end of the screw 4 penetrates into the assembly groove 302 and is rotatably connected to the bottom of the above-mentioned assembly groove 302. A guide rod 401 is provided in another assembly groove 302. Four drive blocks 402 are equidistantly arranged on the screw 4 and the guide rod 401.

[0029] Four sets of limiting components 5 are also arranged in the wire slot 301. Each set of limiting components 5 includes a pair of pressing plates 501 fixedly connected to the driving block 402 on the same horizontal plane, and pressing blocks 502 are fixedly connected to the bottoms of the pair of pressing plates 501.

[0030] Each set of limiting components 5 further includes a pair of supporting plates 503 fixed in the assembly groove 302. A pair of grooves 5030 are formed in the top of the supporting plate 503, and a buffer member cooperating with the pressing block 502 is arranged in the grooves 5030.

[0031] Refer to Figure 5 , the buffer member includes a pair of insulating springs 504 arranged in the grooves 5030, and a supporting plate 505 is fixedly connected to the tops of the pair of insulating springs 504.

[0032] Furthermore, when the pressing plate 501 descends and presses the wire passing through the first arc-shaped groove, as the pressing plate 501 descends, the pressing block 502 presses the supporting plate 505, and the supporting plate 505 presses the insulating spring 504. Thus, while ensuring the limiting and fixing effect on the wire, it has a certain buffering effect and can avoid the situation of pressing or even breaking the wire.

[0033] Refer to Figure 2 , Figure 3 and Figure 4 , a through hole communicating with the assembly groove 302 is formed in the top of the housing 3, and a driving rod is fitted in the through hole. The driving rod is fixedly connected to a screw rod 4.

[0034] Furthermore, a knob is arranged at the end of the driving rod. By operating the knob, the driving rod rotates, and then the screw rod 4 can be driven to rotate. A circle of anti-slip protrusions is arranged on the surface of the knob.

[0035] Refer to Figure 1 and Figure 2 , a pair of screw holes 101 are formed on both sides of the outside of the electricity meter body 1.

[0036] Furthermore, a pair of screw holes 101 are formed on both sides of the outside of the electricity meter body 1. The limiting device 2 can be selectively installed on the left surface or the right surface of the electricity meter body 1 according to the installation position of the electricity meter body 1 in the meter box.

[0037] Refer to Figure 2 A pair of rectangular plates 6 are arranged on the housing 3. Circular holes are formed on both of the pair of rectangular plates 6, and screws 7 are fitted in the circular holes. The screws 7 pass through the circular holes and are in threaded cooperation with the screw holes 101.

[0038] Furthermore, the rectangular plate 6 and the screw 7 are used to fixedly install the limiting device 2.

[0039] Refer to Figure 5The surfaces of the pressing plate 501 and the supporting plate 503 are both provided with a first arc groove.

[0040] Furthermore, the first arc-shaped groove is provided to fit the positioning of the wire, facilitate the positioning of the wire, and avoid damage to the wire caused by excessive squeezing after positioning.

[0041] Reference Figure 4 and Figure 5 The driving block 402 is provided with a through hole and a threaded hole respectively. The through hole is clearance-matched with the guide rod 401 , and the threaded hole is thread-matched with the screw rod 4 . The driving block 402 is also provided with a second arc groove.

[0042] Furthermore, the second arc groove is also provided to fit the positioning of the wire, to facilitate the positioning of the wire, and to avoid damage to the wire due to excessive squeezing after positioning.

[0043] Working principle: After the wires are fixedly connected to the connecting terminals inside the electric energy meter body 1, the wires passing through the electric energy meter body 1 are successively passed through the first arc groove on the support plate 503, and the knob is turned to rotate the drive rod, which can then drive the screw 4 to rotate. The rotation of the screw 4 simultaneously causes the four drive blocks 402 to descend, and the descending of the drive blocks 402 causes the pressure plate 501 to descend. After the pressure plate 501 descends, it contacts the wires, and cooperates with the support plate 503 to achieve synchronous limit processing of multiple wires, saving operation time, avoiding the staggered distribution of wires inside the meter box, optimizing the space utilization inside the meter box, and bringing convenience to subsequent maintenance and overhaul work. At the same time, by positioning the wires outside the electric energy meter body 1, it is effectively prevented that the wires inside the electric energy meter body 1 are loosened due to the pulling of the wires when connecting other devices, thereby ensuring the normal operation and metering accuracy of the electric energy meter body 1, and reducing the risk of safety accidents caused by loose wires, thereby enhancing the safety of the equipment.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
