Description

Technical Field

[0001] This utility model relates to the field of electricity meter fixing, and more specifically, to an insulation testing and fixing device for smart electricity meters. Background Technology

[0002] As the core equipment for data acquisition in smart grids, smart meters undertake key functions such as energy metering, data transmission, and user-end control. Their insulation performance directly determines the safety of grid operation and the service life of the equipment. According to national and international mandatory standards such as GB / T17215 and IEC62052-11, smart meters must pass core safety regulations such as insulation resistance test and withstand voltage test before leaving the factory to verify the insulation withstand capability between live parts and the casing, and to prevent leakage, short circuit or electric shock accidents during use. With the large-scale construction of smart grids and the increase in smart meter production capacity, the efficiency, stability and ease of operation of the insulation testing process have become key factors restricting the improvement of production line quality and efficiency.

[0003] Existing testing devices mostly rely on manual fixing methods, requiring dedicated operators to complete processes such as positioning, clamping, and disassembly. This results in long testing times for a single unit, making it difficult to adapt to the needs of mass production. While existing automated fixing equipment, such as dual-robotic arm testing devices, can improve efficiency, they suffer from problems such as complex structure, high cost, and difficult maintenance. Furthermore, their rigid connection design makes it difficult to adapt to the testing requirements of different types of electricity meters, resulting in insufficient flexibility. Therefore, we propose a smart electricity meter insulation testing fixing device. Utility Model Content

[0005] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a smart energy meter insulation testing and fixing device, including a base. A placement groove is formed on the upper surface of the base. A bearing plate is slidably connected to the inner wall of the placement groove. A sliding groove and a clearance groove are formed on the inner wall of the placement groove, and the sliding groove and clearance groove communicate internally. A displacement plate is slidably connected inside the sliding groove. A ratchet is fixedly connected to the upper surface of the displacement plate.

The end of the telescopic cylinder 9 is rotatably connected to the inner wall of the clearance groove 5. A clamping contact assembly is provided on the displacement plate 6.

[0029] Through the cooperation between the base 1, placement groove 2, bearing plate 3, sliding groove 4, clearance groove 5, displacement plate 6, ratchet 7, telescopic rod 8, telescopic cylinder 9, L-shaped rod 10, and arc rod 11, the bearing plate 3 drives the arc rod 11 to rotate when the energy meter is pressed down, thereby driving the displacement plate 6 to retract inward and quickly clamp the energy meter with the help of the self-locking action of the ratchet 7 and the sliding plate 23. This solves the problem of long time consumption for manual fixing and disassembly and improves the efficiency of batch testing. Example

[0030] The smart energy meter insulation testing and fixing device provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the clamping contact assembly includes a fixing plate 12, which is fixedly connected to the displacement plate 6. A mounting plate 13 is provided on the surface of the fixing plate 12 away from the displacement plate 6. A rubber block 14 for filling the movement gap of the ratchet 7 is fixedly connected to the surface of the mounting plate 13 away from the fixing plate 12. A hole 15 is formed on the surface of the rubber block 14 away from the mounting plate 13, and a fixing bolt 16 for fixing is provided inside the hole 15. The rubber block 14, the mounting plate 13, and the fixing plate 12 are fixedly connected by the fixing bolt 16. Two guide rods 17 for guiding are fixedly connected to the inner wall of the sliding groove 4. The displacement plate 6... The fixed connection has two connecting ears 18, which are slidably sleeved on the outer surface of the guide rod 17. A first spring 19 for resetting is fixedly connected between the connecting ears 18 and the inner wall of the sliding groove 4. A second spring 20 is fixedly connected between the end of the telescopic rod 8 and the bottom wall of the telescopic cylinder 9. A rectangular frame 21 is provided on the base 1. An outer cylinder 22 is fixedly connected to the lower surface of the rectangular frame 21. The outer cylinder 22 slides through the interior of the sliding groove 4. A sliding plate 23 for cooperating with the ratchet 7 to restrict reverse movement is slidably connected inside the outer cylinder 22. A third spring 24 is fixedly connected between the upper surface of the sliding plate 23 and the top wall of the outer cylinder 22.

[0031] Through the cooperation between the fixed plate 12, mounting plate 13, rubber block 14, hole 15, fixing bolt 16, guide rod 17, connecting ear 18, first spring 19, second spring 20, rectangular frame 21, outer cylinder 22, sliding plate 23, and third spring 24, the rubber block 14 achieves flexible contact to compensate for the gap of ratchet 7. Furthermore, after the outer cylinder 22 is lifted by the rectangular frame 21 to release the lock, the first spring 19 automatically resets the displacement plate 6, further improving the clamping stability and ease of operation.

[0032] The usage process of the smart energy meter insulation testing and fixing device provided by this utility model is as follows:

[0033] When performing insulation testing on a smart energy meter, the energy meter is first placed on the upper side of the support plate 3. Then, it is manually pressed down, causing the support plate 3 to move downwards. As the support plate 3 moves, it simultaneously compresses the arc-shaped rod 11, causing it to move. Since the arc-shaped rod 11 is fixedly connected to the telescopic cylinder 9 via the L-shaped rod 10, and the telescopic cylinder 9 is rotatably connected to the inner wall of the relief groove 5, the arc-shaped rod 11, the L-shaped rod 10, the telescopic cylinder 9, and the telescopic rod 8 will all move in a circular motion around the rotatable connection point between the telescopic cylinder 9 and the relief groove 5. The movement of the telescopic rod 8 can drive the displacement plate 6 to retract inwards. When the displacement plate 6 retracts, it simultaneously stretches the first spring 19 via the connecting ear 18. At the same time, when the displacement plate 6 moves, the thorn on its upper side... The inclined surface of the tooth 7 contacts the sliding plate 23, forcing the sliding plate 23 to move upward. When the sliding plate 23 moves, it will compress the third spring 24. After the ratchet 7 passes, the sliding plate 23 will be reset by the elastic force of the third spring 24, preventing the displacement plate 6 from moving in the opposite direction. When the displacement plate 6 moves, it will also drive the rubber block 14 to move by the fixed plate 12 and the mounting plate 13. After the rubber block 14 moves, it will contact the outer surface of the energy meter to achieve fixation. The deformation of the rubber block 14 can compensate for the gap between multiple ratchet teeth 7. When the clamping is removed, simply pull the rectangular frame 21 upward to make the outer cylinder 22 and the sliding plate 23 rise synchronously and disengage from the ratchet 7. The displacement plate 6 can be pulled back by the elastic force of the first spring 19 to achieve reset.
