Description

Technical Field

[0001] This utility model relates to the technical field of electricity metering boxes, specifically to an electricity metering box with secure wiring. Background Technology

[0002] An electricity metering box is a device used to measure and record electricity consumption. It is typically installed in a power system, especially on the user side (such as residential, commercial, and industrial users), to monitor and measure electricity usage. It usually includes electrical components such as meters (e.g., smart meters, mechanical meters), circuit breakers, and terminals, and is responsible for electricity metering, protection, and distribution functions.

[0003] The wiring process for an electricity metering box includes steps such as incoming line wiring, electricity meter wiring, outgoing line wiring, and grounding wire wiring. While existing electricity metering boxes can meet normal wiring requirements and ensure secure connections under normal operating conditions, exposed wires in outdoor or industrial environments are susceptible to vibration or wind, leading to loosening of the wiring within the metering box over time. This can result in electrical safety hazards, inaccurate metering, and equipment damage. Therefore, we propose a more securely wired electricity metering box. Utility Model Content

[0004] The purpose of this utility model is to provide a securely wired power metering box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a securely wired electricity metering box, comprising a box body and a box cover hinged to the box body. The bottom end of the box body is symmetrically provided with inlet and outlet holes. The inner walls of the two inlet and outlet holes are fixedly connected to discs. Each of the two discs is provided with a wire threading mechanism. The wire threading mechanism includes a stud and multiple wire threading slots. The multiple wire threading slots are arranged in a ring array around the center of the disc and are opened through the upper edge of the disc. The inner walls of the multiple wire threading slots near the center of the disc are provided with rectangular slots. The inner walls of the multiple rectangular slots near the center of the disc are fitted with rectangular plates. The stud is fixedly connected to the upper center of the disc, and a linkage mechanism is provided between the stud and the multiple rectangular plates.

[0006] Preferably, the linkage mechanism includes an internally threaded tube, which is threaded onto the upper edge of the outer wall of the stud. The lower end of the internally threaded tube is rotatably connected to a collar, which is slidably fitted onto the outer wall of the stud. Multiple support rods are rotatably connected to the outer wall of the collar in a circular array around its center. Each of the multiple support rods is rotatably connected to a T-shaped block at the end away from the collar. The multiple T-shaped blocks are slidably disposed in the upper inner wall of the disc. Each of the multiple T-shaped blocks is fixedly connected to a connecting column at the end away from the stud. The multiple connecting columns are slidably disposed in the inner wall of the disc. The ends of the multiple connecting columns away from the stud are respectively fixedly connected to the wall surfaces of multiple rectangular plates near the stud.

[0007] Preferably, the upper end of the disc is provided with T-shaped grooves corresponding to multiple T-shaped blocks, and the multiple T-shaped grooves slide in cooperation with the multiple T-shaped blocks respectively.

[0008] Preferably, the inner wall of the disc is provided with cylindrical grooves corresponding to multiple connecting columns, and the multiple cylindrical grooves are slidably engaged with the multiple connecting columns.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 - Figure 5 The diagram shows a securely wired electricity metering box, comprising a box body 1 and a box cover 2 hinged to the box body 1. The bottom end of the box body 1 is symmetrically provided with inlet and outlet holes 17. The inner walls of the two inlet and outlet holes 17 are fixedly connected to discs 3. Both discs 3 are provided with a wire threading mechanism, which includes studs 4 and multiple wire threading grooves 10. The multiple wire threading grooves 10 are arranged in a ring around the center of the discs 3 and are opened through the upper edge of the discs 3. The inner walls of the multiple wire threading grooves 10 near the center of the discs 3 are provided with rectangular grooves 12. The inner walls of the multiple rectangular grooves 12 near the center of the discs 3 are attached with rectangular plates 15. The studs 4 are fixedly connected to the upper center of the discs 3, and a linkage mechanism is provided between the studs 4 and the multiple rectangular plates 15.

[0020] Please see Figure 2 and Figure 3 The linkage mechanism shown in the figure includes an internally threaded tube 5, which is threaded onto the upper edge of the outer wall of the stud 4. The lower end of the internally threaded tube 5 is rotatably connected to a collar 6, which is slidably fitted onto the outer wall of the stud 4. The outer wall of the collar 6 is rotatably connected to multiple support rods 7 in a circular array around its center. The ends of the multiple support rods 7 away from the collar 6 are rotatably connected to T-shaped blocks 14. The multiple T-shaped blocks 14 are slidably disposed in the upper inner wall of the disc 3. The ends of the multiple T-shaped blocks 14 away from the stud 4 are fixedly connected to connecting posts 9. The multiple connecting posts 9 are slidably disposed in the inner wall of the disc 3. The ends of the multiple connecting posts 9 away from the stud 4 are respectively fixedly connected to the wall surface of multiple rectangular plates 15 near the stud 4.

[0021] Please see Figure 2 and Figure 4 In the figure, the upper end of the disc 3 is provided with T-shaped grooves 8 corresponding to multiple T-shaped blocks 14, and the multiple T-shaped grooves 8 slide with the multiple T-shaped blocks 14 respectively.

[0022] Please see Figure 4 In the figure, the inner wall of the disc 3 is provided with columnar grooves 16 corresponding to multiple connecting columns 9. The multiple columnar grooves 16 are slidably engaged with the multiple connecting columns 9. The columnar grooves 16 are connected to the T-shaped grooves 8 and the wire grooves 10.

[0023] Please see Figure 2 and Figure 3 In the diagram, rectangular rubber pads 11 are fixedly connected to the walls of multiple rectangular plates 15 away from the studs 4. Specifically, the rectangular rubber pads 11 and the wires rely on the friction between them to make the rectangular plates 15 clamp the wires more securely.

[0024] Please see Figure 2 In the figure, the outer wall of the internally threaded tube 5 is provided with multiple anti-slip grooves 13 arranged in a ring around its center; specifically, the anti-slip grooves 13 can increase the friction between the fingers and the internally threaded tube 5, so that the internally threaded tube 5 has a good anti-slip effect when rotating.

[0025] Working principle: First, open the cover 2 on the housing 1. Then, pass multiple wires through the multiple wire slots 10 on the disc 3 of one of the inlet / outlet holes 17 into the housing 1 and connect them to the terminals of the power metering device inside the housing 1. Then, rotate the internal threaded tube 5 corresponding to the disc 3 downwards. The internal threaded tube 5 will rotate downwards on the outer wall of the stud 4 on the disc 3, and the internal threaded tube 5 will drive the collar 6 to slide downwards on the outer wall of the stud 4 (during this process, the internal threaded tube 5 will rotate at the upper end of the collar 6). The collar 6 will drive the multiple support rods 7 on it to move downwards. The ends of the multiple support rods 7 away from the collar 6 will move away from the stud 4 and drive the T-shaped blocks 14 on them to move (during this process, the multiple support rods 7 will also rotate between the collar 6 and their corresponding T-shaped blocks 14). The multiple T-shaped blocks 14 will... The components slide away from the center point of the disk 3 in the T-shaped groove 8 on their respective disks 3. The multiple T-shaped blocks 14 will drive the connecting columns 9 on their respective disks 3 to slide away from the center point of the disk 3 in the cylindrical groove 16 on their respective disks 3. The multiple connecting columns 9 will drive the rectangular plates 15 on their respective disks 12 to slide away from the center point of the disk 3 in the corresponding rectangular groove 12. The multiple rectangular plates 15 will drive the rectangular rubber pads 11 on their respective disks to move closer to the wires in their respective wire slots 10 until the rectangular rubber pads 11 and the wires are tightly attached. Then the wires can be clamped and fixed between the rectangular rubber pads 11, the rectangular grooves 12 and the inner wall of the inlet and outlet holes 17. At this time, the rotation of the internal thread tube 5 can be stopped. Similarly, the wires in the other inlet and outlet holes 17 can also be clamped and fixed in the same way. Finally, the box cover 2 can be closed. The operation is simple.

[0026] It should be noted that the multiple wires in the two inlet and outlet holes 17 of this metering box can be clamped and fixed simultaneously. The clamping operation is simple and avoids the problem of loosening of the wiring inside the electricity metering box due to vibration or shaking of the exposed wires. This helps to ensure electrical safety and metering accuracy.
