[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to embodiments.

[0021] Example: A split-type quick-plug energy meter, such as... Figures 1-9 As shown, the split-type energy meter includes a first module 1 and a second module 2. The main structure of the split-type energy meter is divided into a first module 1 and a second module 2. A sliding column 3 is slidably connected to one side of the first module 1. A first spring 4 is provided at one end of the sliding column 3. The first spring 4 is located inside the first module 1. A fixing plate 5 is fixedly connected to the other end of the sliding column 3. A connecting column 6 is provided on one side of the fixing plate 5. The design of the sliding column 3 can limit the position of the fixing plate 5. At the same time, the design of the first spring 4 can provide power for the subsequent reset of the fixing plate 5. It should be noted that the connecting column 6 is made of copper. Professionals in this field can freely select according to the actual situation. The connecting column 6 is square. A contact plate 7 is slidably connected to the middle of the fixing plate 5. One end of the contact plate 7 is fixedly connected to the first module 1. The second module 2 has a connecting hole 8 and a fixing hole 9 on one side. The connecting hole 8 is used to slide with the connecting post 6, and the fixing hole 9 is used to slide with the contact plate 7. The sliding connection between the connecting post 6 and the connecting hole 8 enables the first module 1 and the second module 2 to be connected, reducing the steps required to connect the first module 1 and the second module 2.

[0022] The second module 2 has a sliding groove 10 inside, and a pair of fixed rods 11 are slidably connected inside the second module 2. A contacting wedge 12 is fixedly connected to one side of each fixed rod 11. The inclined surface of the contacting wedge 12 is used to abut against one end of the contact plate 7. The design of the contact plate 7 abutting against the inclined surface of the contacting wedge 12 is described in [reference needed]. Figure 4 This allows the contact plate 7 to push the contact block 12 and the fixing rod 11 to slide to both sides when they come into contact with the inclined surface of the contact block 12. One end of the fixed rod 11 is fixedly connected to a return spring 16, and the other end of the return spring 16 is fixedly connected to the inside of the second module 2. The design of the return spring 16 enables the fixed rod 11 to be squeezed and deformed when it slides to both sides, thus providing power for the subsequent reset of the fixed rod 11.

[0023] A limiting groove 13 is provided on the fixed rod 11, and a sliding connecting block 14 is slidably connected in the limiting groove 13. The design of the limiting groove 13 can limit the position of the sliding connecting block 14 and prevent the sliding connecting block 14 from shifting when it slides. The two sides of the sliding connecting block 14 are slidably connected to the sliding groove 10, and a second spring 15 is fixedly connected between the sliding connecting block 14 and the fixed rod 11.

[0024] A pair of positioning grooves 17 are provided on one side of the sliding connecting block 14. Each positioning groove 17 is slidably connected to a clamping connecting block 18. The design of the positioning grooves 17 can limit the sliding trajectory of the clamping connecting block 18 and prevent the position of the clamping connecting block 18 from shifting during the sliding process. The clamping connecting block 18 is slidably connected to the sliding connecting block 14. A contact slope 19 is provided on one side of the clamping connecting block 18. The sliding connecting block 14 and the clamping connecting block 18 are used to contact the connecting post 6. With the contact slope 19, when the sliding connecting block 14 drives the clamping connecting block 18 to slide towards the connecting post 6, the connecting post 6 can be locked between the two clamping connecting blocks 18 under the guidance of the contact slope 19, preventing jamming.

[0025] Each side of the clamping connecting block 18 is fixedly connected to a sliding column 20, and the other end of the sliding column 20 is fixedly connected to a fixing block 21. A third spring 22 is fixedly connected between the fixing blocks 21. The design of the third spring 22 can provide power for the subsequent reset of the clamping connecting block 18.

[0026] The sliding connecting block 14 has a sliding plate 23 internally connected to it. The sliding plate 23 has a guide slope 24 inside, which abuts against the sliding column 20. The design of the abutment between the sliding column 20 and the guide slope 24 is described in [the original text]. Figure 7This allows the sliding plate 23 to slide downwards, and under the guidance of the guide slope 24, the sliding columns 20 on both sides can drive the clamping connecting blocks 18 to move closer to the center, so that the clamping connecting blocks 18 on both sides can clamp the connecting column 6, and so that the clamping connecting blocks 18 on both sides can contact the connecting column 6.

[0027] A sliding ball rod 25 is fixedly connected to one side of the sliding plate 23. The sliding ball rod 25 is located inside the sliding connecting block 14. The design of the sliding ball rod 25 enables the sliding plate 23 to slide down together when the sliding ball rod 25 moves down.

[0028] The limiting groove 13 is provided with a guide groove 26 and a guide groove 27 inside. The guide groove 26 and the guide groove 27 are connected to each other and are opened inside the fixed rod 11. The sliding ball rod 25 is slidably connected to the guide groove 26 and the guide groove 27. With the guidance of the guide groove 26, when the sliding ball rod 25 slides in the guide groove 26, it can drive the sliding ball rod 25 and the sliding plate 23 to slide down together.

[0029] One end of the fixed rod 11 is fixedly connected to a transmission rack 28, and the transmission rack 28 is meshed with a transmission gear 29. The transmission gear 29 is rotatably connected to the inside of the second module 2. Through the design of the transmission rack 28 and the transmission gear 29, when the fixed rod 11 slides to both sides, it can drive the transmission rack 28 to slide together, so that the transmission rack 28 can drive the transmission gear 29 to rotate.

[0030] A control spring 30 is fixedly connected to one side of the transmission gear 29, and a connecting rod 31 is fixedly connected to the other end of the control spring 30. The connecting rod 31 is used to abut against the connecting post 6. Through the design of the control spring 30, after the control spring 30 drives the connecting rod 31 to contact the connecting post 6, if the fixed rod 11 continues to slide to both sides, the control spring 30 will deform to prevent jamming.

[0031] When installing a split-type energy meter, firstly, the position of the second module 2 needs to be fixed. Then, the connecting post 6 on the first module 1 is aligned with the connecting hole 8, and the contact plate 7 is aligned with the fixing hole 9. Then, the first module 1 is pushed towards the second module 2, so that the connecting post 6 can be inserted into the connecting hole 8, and the contact plate 7 can be inserted into the fixing hole 9. After the connecting post 6 is inserted into the fixing hole 9, one side of the fixing plate 5 is in contact with the second module 2. Then, the first module 1 is pushed towards the second module 2, which causes the sliding post 3 to slide into the interior of the first module 1, and at the same time, the first spring 4 is deformed. When the sliding column 3 slides into the first module 1, the contact plate 7 begins to slide into the fixing hole 9. As the contact plate 7 continues to slide into the fixing hole 9, it comes into contact with the inclined surface of the contact block 12. Through the contact plate 7's contact with the contact block 12, the contact block 12 can be driven to slide together with the fixing rod 11, allowing the contact block 12 and the fixing rod 11 to slide to both sides. While the fixing rod 11 slides to both sides, it also drives the sliding connecting block 14, the second spring 15, and the clamping connecting block 18 to slide together. See Figure 5 When the abutting inclined block 12 drives the fixed rod 11, sliding connecting block 14, second spring 15 and clamping connecting block 18 to slide to the left, the sliding connecting block 14 will slide closer to the connecting post 6, so that the sliding connecting block 14 can abut against the connecting post 6, thereby connecting the sliding connecting block 14 with the connecting post 6. After the sliding connecting block 14 contacts the connecting post 6, the abutting inclined block 12 will continue to drive the fixed rod 11 to slide to the left, which will cause the second spring 15 to deform, providing power for subsequent reset. When the sliding connecting block 14 abuts against the connecting post 6, the position of the sliding connecting block 14 is restricted, preventing it from sliding further to the left with the fixed rod 11. Figure 7 At this time, the fixed rod 11 will continue to slide to the left. While the fixed rod 11 is sliding, it will drive the guide groove 26 and the guide slide groove 27 to slide together. The guide groove 26 guides the sliding ball rod 25, so that the sliding ball rod 25 can slide down. While the sliding ball rod 25 is sliding down, it will drive the sliding plate 23 to slide together. When the sliding plate 23 is sliding down, the guide slope 24 guides the sliding column 20, so that the sliding column 20 can drive the clamping connecting block 18 to move towards the middle. This allows the clamping connecting blocks 18 on both sides to clamp the connecting column 6 in the middle, so that multiple surfaces of the connecting column 6 on the first module 1 can be connected to the second module 2, further increasing the stability of the connection between the first module 1 and the second module 2 and preventing poor contact problems during subsequent use. It should be noted that, through the design of the guide groove 27, after the clamping connecting block 18 clamps the connecting post 6 in the middle, the fixing rod 11 will continue to slide to the left. At this time, the sliding ball rod 25 will slide in the guide groove 27, which can prevent jamming.

[0032] See Figure 5As the fixed rod 11 slides to the left, it drives the transmission rack 28 to slide to the left as well. Simultaneously, the transmission rack 28 drives the transmission gear 29 to rotate. This rotation causes the control spring 30 and the connecting rod 31 to move together, allowing the connecting rod 31 to contact another surface of the connecting post 6. Once the connecting rod 31 contacts the surface of the connecting post 6, the transmission rack 28 continues to drive the transmission gear 29 to rotate, causing the control spring 30 to deform. This ensures that the entire surface of the connecting rod 31 is tightly pressed against the connecting post 6. This design allows multiple surfaces of the connecting post 6 to connect with the second module 2, further increasing the stability of the connection between the first module 1 and the second module 2 and preventing poor contact during subsequent use.

[0033] When the connection between the first module 1 and the second module 2 is completed, see Figure 7 At this point, the two sides of the contact plate 7 will abut against the straight surface of the right end of the contact ramp 12. Through this design, the contact plate 7 will be clamped between the two contact ramps 12. Then, the position of the first module 1 is fixed, so that the first module 1 and the second module 2 are connected. When it is necessary to disassemble the first module 1 and the second module 2 later, it is only necessary to first release the fixation of the first module 1 and the second module 2. It should be noted that the first module 1 and the second module 2 can be fixed to the guide rail or the selected position in advance by fixing bolts. Professionals in this field can choose freely according to the actual situation. Then, the fixation can be released by controlling the fixing bolts. Then, the first module 1 can be pulled. The block 1 is separated from the second module 2, allowing the contact plate 7 to slide out of the fixing hole 9. Then, the fixing rods 11 on both sides slide towards the middle under the action of the return spring 16. Under the push of the second spring 15, the sliding ball rod 25 can slide upward through the guide groove 26. As the sliding ball rod 25 slides upward, it will drive the sliding plate 23 to slide together, so that the guide slope 24 no longer abuts against the sliding column 20. Under the action of the fixing block 21 and the third spring 22, the sliding column 20 can drive the clamping connecting block 18 to slide to both sides, thereby releasing the clamping of the connecting column 6. At this time, under the action of the first spring 4, the connecting column 6 is still in the connecting hole 8 and has not moved. As the fixing rod 11 slides back, it will drive the transmission rack 28 to slide together, causing the transmission gear 29 to drive the control spring 30 and the connecting rod 31 to move back, so that the connecting rod 31 no longer contacts the connecting post 6. At this time, the contact plate 7 has completely slid out of the fixing hole 9. As the first module 1 and the second module 2 continue to move away from each other, the connecting post 6 will then slide out of the connecting hole 8, completing the separation of the first module 1 and the second module 2. With this design, when the first module 1 and the second module 2 are connected, there will be no friction between the connecting post 6 and the sliding connecting block 14, the clamping connecting block 18 and the connecting rod 31, which can reduce the wear of parts. This also prevents poor contact caused by wear of the connecting post 6, the sliding connecting block 14, the clamping connecting block 18 and the connecting rod 31 during subsequent multiple connections and uses, thereby increasing the service life of the equipment.

[0034] In this embodiment: During installation, the connecting post 6 on the first module 1 is inserted into the connecting hole 8 of the second module 2. The abutment plate 7 then enters the fixing hole 9 and abuts against the abutment inclined blocks 12 on both sides. Utilizing the inclined plane principle, the linear motion is converted into a lateral clamping force, causing the fixing rod 11 to drive the sliding connecting block 14 and the clamping connecting block 18 to hug the connecting post 6 from both sides. At the same time, the transmission rack 28 on the side of the fixing rod 11 drives the transmission gear 29 to rotate, thereby causing the control spring 30 and the connecting rod 31 to press tightly against the other surface of the connecting post 6, forming a full-enclosed clamping of the four surfaces of the connecting post 6, greatly improving the vibration resistance and anti-loosening ability, ensuring... Good electrical contact is ensured. During disassembly, by first releasing the restraint of the fixing plate 5 and pulling it outward, the contact plate 7 slides out of the fixing hole 9. The return spring 16, the second spring 15, and the third spring 22 quickly return to their original positions under elastic action, causing the sliding connecting block 14, the clamping connecting block 18, and the connecting rod 31 to loosen first. Then the connecting column 6 slides out of the connecting hole 8. This "loosen first, then separate" logic completely avoids frictional wear between the connecting column 6 and the clamping parts. Combined with the anti-jamming design of the guide groove 26 and the guide slide 27, it not only ensures the contact accuracy after multiple disassemblies and reassemblies, but also significantly extends the overall service life of the equipment.
