[0002] The installation of electricity meters is of great importance in the power industry. It is a key link in ensuring accurate electricity measurement, effective energy management and stable power supply. The installation and removal of electricity meters require electricians with certain experience and skills to ensure their normal operation and accurate measurement of electricity consumption.

[0003] The replacement of electricity meters has become a frequent and important task in power operation and maintenance. However, traditional electricity meters have many significant problems in the wiring and replacement process, which seriously restricts the efficiency and quality of power operation and maintenance. From the wiring point of view, electricity meters usually use screw-tightening terminals. Operators need to use tools such as screwdrivers to insert the wire cores of the wires one by one into the wiring holes inside the electricity meter and tighten the screws. This process is not only time-consuming and labor-intensive, but also in actual operation, if the wires are not wound properly or the screws are not tightened with the right force, it is very easy to cause poor contact, causing safety hazards such as heating and sparks. At the same time, in the replacement of electricity meters, traditional electricity meters are generally fixed to the wall or distribution box with bolts. When installing or disassembling, they need to accurately align the installation holes, and then use wrenches and other tools to tighten the bolts. The operation process is relatively complicated.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1 - Figure 2 A device for facilitating replacement of an electric energy meter comprises a fixing base 1, an electric energy meter sleeve 2 is fixedly mounted on the top outside of the fixing base 1, the electric energy meter sleeve 2 is U-shaped when viewed from above, a mounting bracket 7 is fixedly mounted on the outside of one edge of the electric energy meter sleeve 2 near the bottom end, a guide assembly is arranged inside the bottom end of the electric energy meter sleeve 2, the function of the guide assembly is to guide and straighten the cable inserted into the bottom end of the electric energy meter sleeve 2; the guide assembly comprises a plurality of guide cylinders 3, and the plurality of guide cylinders 3 are slidably mounted at equal intervals through the bottom end of the electric energy meter sleeve 2.

[0020] A fixing ring 4 is fixedly installed on the outside of one side of the top of several guide cylinders 3, and two limit rods 5 are symmetrically arranged longitudinally on the bottom ends of both sides of the fixing ring 4. One end of each limit rod 5 is slidably installed on the outside of one side of the bottom end of the electric energy meter sleeve 2.

[0021] A reset spring 6 is sleeved and installed on one side of each limiting rod 5 , and both ends of the reset spring 6 are respectively installed on one side of the fixing ring 4 and the bottom end of the electric energy meter sleeve 2 .

[0022] In this embodiment, when the device is in use, the fixing seat 1 and the electric energy meter sleeve 2 are first fixedly installed in the corresponding electric meter box by bolts, and then the wire is inserted into the inside of the guide tube 3. During the insertion process, the vertical guiding setting of the guide tube 3 is used to straighten the inserted wire, ensuring that the straightened wire can be accurately inserted into the wiring hole at the bottom of the electric energy meter, ensuring the accuracy of the overall connection. At the same time, when designing and manufacturing, it is necessary to ensure that the outer diameter of the guide tube 3 is larger than the inner diameter of the wiring hole at the bottom of the electric energy meter, so that When the electric energy meter is placed into the electric energy meter sleeve 2 later, as the electric energy meter continues to be inserted, the bottom wall of the electric energy meter sleeve 2 will contact the guide tube 3, causing the guide tube 3 to automatically press down, leaking the straightened battery cell inside, and inserting it into the wiring hole at the bottom of the electric energy meter. There will be no movement conflict, ensuring the stability of replacement and docking. At the same time, after the electric energy meter is subsequently taken out, the guide tube 3 will also rebound and reset synchronously through the guidance of the limit rod 5 and the rebound of the reset spring 6, ensuring that the subsequent new wire can be straightened again, and the whole can be reused.

[0023] Example 2: Please refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10 This embodiment further illustrates the first embodiment. A screwing assembly is provided inside the top of the mounting frame 7. The function of the screwing assembly is to synchronously screw multiple cable fixing bolts inside the bottom of the electric energy meter.

[0024] The twisting assembly includes a movable frame 8, a limiting rack 12 and several rotating columns 14. The movable frame 8 is slidably fitted on the outside of the top of the mounting frame 7. The movable frame 8 is located on one side of the top of the mounting frame 7 and is laterally fixedly installed on the outside. Several rotating columns 14 are longitudinally arranged on the outside of one side of the limiting rack 12, and an insulating screwdriver head 15 is fixedly installed on the outside of the bottom end of several rotating columns 14.

[0025] A driving assembly is provided on the outside of one side of the movable frame 8 close to the side edge of the electric energy meter sleeve 2 .

[0026] The movable frame 8 is set in an inverted U shape. A through hole 13 is provided inside the side of the movable frame 8 close to each rotating column 14. Each rotating column 14 is slidably installed inside the through hole 13 on the corresponding side. A gear ring 16 is provided outside the external side of the rotating column 14 located at the top of the movable frame 8.

[0027] The bottom end of the gear ring 16 is rotatably mounted on the outside of one side of the top end of the moving frame 8 , and one side of the gear ring 16 is meshed with one side of the limiting rack 12 .

[0028] Several limit sliders 18 are fixedly installed at equal angles around the outer surface of the rotating column 14. A limit slot 17 is embedded on the inner wall of the gear ring 16 on one side close to the several limit sliders 18. Each limit slider 18 is longitudinally slidably installed inside the limit slot 17 on the corresponding side, and the outer surface of the limit slider 18 does not contact the inner wall of the through hole 13.

[0029] Specifically, it is ensured that when the gear ring 16 drives the rotating column 14 to rotate, the rotating column 14 can also slide longitudinally inside the gear ring 16 to ensure smooth overall operation.

[0030] A support seat 19 is fixedly installed on the outside of the mobile frame 8 near the top side of each rotating column 14, and a rotating shaft 20 is fixedly installed on the top of the rotating column 14. The top of the rotating shaft 20 is rotated and penetrated and engaged with the outside of the top side of the support seat 19. A resistance spring 21 is sleeved through the outside of the rotating shaft 20, and the two ends of the resistance spring 21 are respectively installed on one side of the rotating column 14 and the support seat 19.

[0031] The driving assembly includes two groups of symmetrically arranged auxiliary rods 9, which are respectively fixedly mounted on the outside of the two sides of the electric energy meter sleeve 2 close to the movable frame 8. One end of the two groups of symmetrically arranged auxiliary rods 9 are both slidably mounted on the outside of one side of the corresponding side movable frame 8. A screw rod 10 is embedded and rotatably mounted on the outside of one side of the movable frame 8 close to one of the groups of auxiliary rods 9. One end of the screw rod 10 is threadedly mounted on the outside of one side of the movable frame 8, and an auxiliary handle 11 is fixedly mounted on the through end of the screw rod 10.

[0032] In this embodiment, when the new electric energy meter is replaced and installed inside the electric energy meter sleeve 2, after the electric energy meter is inserted and moved along the electric energy meter sleeve 2 to the bottom end of the electric energy meter sleeve 2, the multiple wiring hole screws on the outside of the electric energy meter are aligned with the bottom ends of the multiple insulating screwdriver heads 15. At this time, it is necessary to twist the wiring hole screws to fix the wire core inserted into the wiring hole. First, rotate the auxiliary handle 11 on one side, and the rotation of the auxiliary handle 11 drives the screw rod 10 on one side to rotate synchronously. Through the screw rod 10 and the movable frame 8 is connected through a threaded connection on one side, and cooperates with the limiting guide of the auxiliary rod 9, so that the screw rod 10 rotates to drive the mobile frame 8 to move laterally on the outer surface of one side of the mounting frame 7. When the mobile frame 8 moves, it will drive the limiting rack 12 on one side to move synchronously. When the limiting rack 12 moves, it will drive the multiple meshing gear rings 16 on one side to rotate. Through the rotation of the gear ring 16, the internal rotating column 14 is driven to rotate, so that the rotating column 14 drives the insulating screwdriver head 15 to rotate, so that the screws of multiple wiring holes are tightened synchronously.

[0033] It should also be noted that during use, the support seat 19, the rotating shaft 20 and the resistance spring 21 are used to resist and squeeze the insulating screwdriver head 15, so as to ensure that after the insulating screwdriver head 15 contacts the screw, the insulating screwdriver head 15 has a certain downward resistance force, ensuring that when it is twisted later, it can press the screw and tighten it, thereby ensuring the overall use effect.

[0034] It should also be noted that when the electricity meter inside the electricity meter sleeve 2 needs to be disassembled, it is only necessary to reverse the auxiliary handle 11, so that the auxiliary handle 11 drives the screw rod 10 to reverse synchronously, so that the screw rod 10 drives the movable frame 8 and the limit rack 12 to move back, so that the limit rack 12 drives multiple gear rings 16, rotating columns 14 and insulating screwdriver heads 15 to rotate in the opposite direction, thereby loosening the wiring hole screws, and then directly removing the electricity meter from the inside of the electricity meter sleeve 2 to complete the disassembly. There is no need for the operator to use a screwdriver to tighten or loosen the screw terminals one by one. The overall operation is convenient, and it can ensure that each screw can be tightened in place to ensure the overall wiring stability.

[0035] Example 3: Please refer to Figure 3 、 Figure 4 、 Figure 7 and Figure 8 This embodiment further illustrates the second embodiment, where a limiting component is provided at the top edge of the mounting frame 7 .

[0036] The limiting assembly includes a rotating rod 1 22 and a rotating rod 2 25. The rotating rod 1 22 is longitudinally rotated and installed at the edge of one side of the top of the mounting frame 7. The rotating rod 25 is longitudinally rotated and installed at the edge of the other side of the top of the mounting frame 7. A positioning gear 1 23 is fixedly installed through the outside of the bottom end of the rotating rod 1 22. One side of the positioning gear 1 23 is meshed with one side of one of the gear rings 16. A positioning gear 26 is fixedly installed through the outside of the bottom end of the rotating rod 2 25. One side of the positioning gear 26 is meshed with one side of the limiting rack 12.

[0037] A pull rod 1 24 is fixedly installed on the top of the rotating rod 1 22, and a pull rod 2 27 is fixedly installed on the top of the rotating rod 2 25. A connecting shaft 28 is fixedly installed on the end of the pull rod 1 24 and the pull rod 2 27 away from the limiting rack 12. The bottom end of the connecting shaft 28 is rotatably engaged with a resistance column 29. An arc-shaped guide groove 30 is embedded on the inner wall of the top end of the fixed seat 1 near the resistance column 29, and the bottom end of the resistance column 29 is embedded and slidably installed inside one side of the guide groove 30.

[0038] In this embodiment, when a new electric energy meter is replaced and installed inside the electric energy meter sleeve 2, the auxiliary handle 11 is rotated to drive the screw rod 10 on one side to rotate synchronously, thereby driving the limit rack 12 and the gear ring 16 to rotate to perform the screw tightening operation. At this time, one of the gear rings 16 will drive the meshing positioning gear 1 23 on one side to rotate, thereby driving the rotating rod 1 22 and the pull rod 1 24 on the top outside to move toward the middle position of the top of the electric energy meter sleeve 2, thereby blocking the top opening side of the electric energy meter sleeve 2, and at the same time, the limit rack 12 will also drive the meshing positioning gear 1 on one side when moving. Gear 2 26 rotates, and through the rotation of positioning gear 26, the rotating rod 2 25 and the pull rod 2 27 are driven to rotate, so that the pull rod 2 27 is also centered to the middle position of the top of the electricity meter sleeve 2, thereby abutting and blocking the other side of the top opening of the electricity meter sleeve 2. At the same time, the pull rod 1 24 and the pull rod 2 27 will also drive the connecting shaft 28 and the abutment column 29 on one side to rotate synchronously along the guide groove 30 when rotating, so that the abutment column 29 rotates close to the top opening of the electricity meter sleeve 2, thereby stably restricting the electricity meter inside the electricity meter sleeve 2, completing the replacement positioning, and the overall use effect is good.

[0039] It should also be noted that when removing the new electricity meter from the inside of the electricity meter sleeve 2, the auxiliary handle 11 is reversed to drive the screw rod 10 on one side to reverse synchronously, so that the limit rack 12 moves back and the gear ring 16 rotates in the opposite direction and resets. By moving the limit rack 12 back and resetting the gear ring 16 in the opposite direction, the top pull rod 1 24 and the pull rod 2 27 are driven to move back and reset synchronously, so that the top of the electricity meter sleeve 2 is no longer restricted. At the same time, it will also drive the resistance column 29 on one side to move back and reset, so that the top of the electricity meter sleeve 2 is no longer restricted. After that, the electricity meter that needs to be replaced in the electricity meter sleeve 2 can be directly pulled out, and the overall operation is convenient.
