Description

Technical Field

[0001] This utility model relates to the field of electricity meter calibration technology, and specifically to an electricity meter calibration device. Background Technology

[0002] As a key metering instrument for measuring electricity consumption, electricity meters are widely used in the generation, supply, and consumption stages of the power system. Their accuracy directly affects electricity billing and the economic operation of the power system. To ensure that the metering accuracy of electricity meters meets the standard requirements, they need to be calibrated regularly using calibration devices.

[0003] However, existing electricity meter calibrators have some problems in use. During calibration, the calibrator usually needs to be manually held by hand, which not only increases the workload of the operator but is also extremely inconvenient, easily leading to instability in the calibration process and affecting its accuracy and reliability. Furthermore, manual hand-held operation can also cause errors in the calibration data due to operator negligence or hand tremors, reducing the quality and efficiency of the calibration work.

[0004] Therefore, we have proposed an electricity meter calibration device. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings and provide an electricity meter calibration device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model is achieved by the following technical solution: an electricity meter calibration device, including a calibrator body, a mounting bracket, and rotatably mounted at both ends of the calibrator body for supporting the calibrator body, including a support part 1 symmetrically arranged on both sides of the calibrator body, which can support the calibrator body through the deflected support part 1;

[0008] An adjustment component is used to adjust the length of the first support part, including a receiving groove formed in the first support part and a second support part slidably inserted inside the receiving groove. By adjusting the total length of the first support part and the second support part, the height of the calibrator body in the supported state can be adjusted.

[0009] As a further improvement to the above solution, the support part is rotatably connected to a connecting shaft with a mounting block fixed at its tail end. The calibrator body has a mounting groove that slides with the mounting block. The calibrator body and the support part can be rotatably connected through the connecting shaft. The mounting groove that slides with the mounting block makes it easy for the user to detach the support part from the calibrator body.

[0010] As a further improvement to the above solution, the outer side of the mounting groove is provided with multiple threaded grooves on the calibrator body, and the support part is threadedly connected with bolts that are threadedly engaged with the threaded grooves. The angle of the support part can be limited by the bolts and the threaded grooves.

[0011] As a further improvement to the above solution, the two ends of the support part located inside the receiving groove are provided with loading grooves, and a locking block is slidably inserted in the loading groove. The support part one is provided with multiple locking grooves that slide with the locking block. Through the cooperation of the locking block and the locking groove, the corresponding position of the support part two can be fixed.

[0012] As a further improvement to the above solution, a limiting plate that slides inside the loading groove is fixed to the end of the locking block located inside the loading groove. The limiting plate can prevent the locking block from detaching from the inside of the loading groove.

[0013] As a further improvement to the above solution, the main body of the calibrator is provided with screws with opposite thread directions at both ends. The outer walls of the screws at both ends are threaded with sleeves fixed on the adjacent support parts. By rotating the screws, the sleeves can be moved through the threaded engagement between the screws and the sleeves.

[0014] As a further improvement to the above solution, both the mounting block and the mounting groove are rectangular structures. By using mounting blocks and mounting grooves that are both rectangular structures, the stability of the support part can be improved.

[0015] As a further improvement to the above solution, a plurality of reset springs are fixed between the limiting plate and the loading groove for pushing the limiting plate to reset. Through the elasticity of the reset springs, the displaced limiting plate can be pushed to reset its displacement.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model, through the coordinated operation of the calibrator body, support part one, receiving groove, support part two, loading groove, limiting plate, return spring, locking block, locking groove, mounting block, connecting shaft, bolt, mounting groove, threaded groove, screw and sleeve, can perform calibration operation on the energy meter. It can support the calibrator when it is inconvenient for the user to hold the calibrator. The height and angle of the calibrator in the supported state can be adaptively adjusted according to the usage needs. The support components can be stored when the user is carrying the calibrator, thus making it convenient for the user to carry the calibrator. The support components can be disassembled according to the usage needs.

[0018] In summary, this utility model has a reasonable structure, can perform calibration operations on electricity meters, can support the calibrator when it is inconvenient for the user to hold the calibrator, and can adaptively adjust the height and angle of the calibrator in the supported state, making it highly flexible and easy to use.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1:

[0030] Combination Figure 1 The electricity meter calibration device in this embodiment includes a calibration instrument body 1:

[0031] Mounting brackets are rotatably mounted at both ends of the calibrator body 1 to support the calibrator body 1, including support parts 2 symmetrically arranged on both sides of the calibrator body 1;

[0032] An adjustment assembly for adjusting the length of the support part 1 2 includes a receiving groove 3 formed in the support part 1 2 and a support part 2 4 slidably inserted inside the receiving groove 3.

[0033] The implementation principle of the electricity meter calibration device in this embodiment is as follows: The voltage test line of the calibrator body 1 is connected to the voltage terminal of the electricity meter, with the positive terminal connected to positive and the negative terminal connected to negative. At this time, the calibrator body 1 can be used to calibrate the electricity meter. When it is inconvenient for the staff to hold the calibrator body 1 during the calibration process, the support part 2 can be pushed to rotate it. At this time, the calibrator body 1 can be supported by the support part 2 on the outside of the calibrator body 1. At this time, the staff does not need to hold the calibrator body 1 to calibrate the electricity meter, which is convenient to use. The tilt angle of the calibrator body 1 can be adjusted by adjusting the rotation angle of the support parts 2 at both ends of the calibrator body 1. When the support part 2 and the calibrator body 1 are at the same level, the support part 2 is stored, which makes it convenient for the user to carry the calibrator body 1. By pulling the support part 4, the support part 4 can slide out or slide into the support part 2. The staff can adjust the total length of the support part 2, thereby adjusting the corresponding height of the calibrator body 1.

[0034] Example 2:

[0035] Combination Figure 3 and Figure 4 Based on embodiment 1, the further improvement of this embodiment is that: the support part 2 is rotatably connected to the connecting shaft 11 with the mounting block 10 fixed at the tail end, and the calibrator body 1 is provided with the mounting groove 13 that slides with the mounting block 10. Through the connecting shaft 11, the calibrator body 1 and the support part 2 can be rotatably connected.

[0036] The mounting groove 13 has multiple threaded grooves 14 on the calibrator body 1. The support part 2 is threadedly connected to a bolt 12 that is threadedly engaged with the threaded groove 14. The angle of the support part 2 can be limited by the bolt 12 and the threaded groove 14. When the angle of the support part 2 needs to be adjusted, the bolt 12 is rotated to disengage from the threaded groove 14, which can pull the support part 2. The rotation of the connecting shaft 11 causes the support part 2 to rotate. When the corresponding angle of the support part 2 is adjusted, the bolt 12 can be rotated to enter the corresponding threaded groove 14. At this time, the corresponding angle of the support part 2 is fixed.

[0037] Example 3:

[0038] Combination Figure 6 and Figure 7 This embodiment, based on embodiment 1, further improves upon the following: A loading groove 5 is provided at the end of the second support portion 4 located inside the receiving groove 3. A locking block 8 is slidably inserted into the loading groove 5. The first support portion 2 has multiple locking slots 9 that slidably engage with the locking block 8. Through the engagement of the locking block 8 and the locking slots 9, the corresponding positions of the second support portion 4 can be fixed. A limiting plate 6, which slides inside the loading groove 5, is fixed at the end of the locking block 8 located inside the loading groove 5. Multiple return springs 7 are fixed between the limiting plate 6 and the loading groove 5 to push the limiting plate 6 back to its original position. When adjustment of the first support portion 2 is required... When the total length is adjusted, the locking block 8 can be pressed to move it. After the displaced locking block 8 is disengaged from the slot 9, the second support part 4 can be pulled. Through the sliding cooperation between the receiving slot 3 and the second support part 4, the second support part 4 can be moved. At this time, the total length of the first support part 2 can be adjusted. After the total length of the first support part 2 is adjusted, the elasticity of the return spring 7 pushes the limit plate 6 and the locking block 8 to move back. When the displaced locking block 8 enters the corresponding slot 9, the second support part 4 is fixed inside the first support part 2, and the total length of the first support part 2 is fixed.

[0039] Example 4:

[0040] Combination Figure 2 and Figure 5 Based on Embodiment 1, this embodiment is further improved in that: the two ends of the calibrator body 1 are provided with screws 15 with opposite thread directions. The outer walls of the two ends of the screws 15 are threaded with sleeves 16 fixed on the adjacent support part 2 4. By rotating the screws 15, the sleeves 16 can be moved through the threaded engagement of the screws 15 and the sleeves 16, which in turn moves the support part 2 4 and the support part 1 2, and moves the connecting shaft 11 and the mounting block 10. When the displaced mounting block 10 is removed from the interior of the mounting groove 13, the support part 1 2 can be removed from the calibrator body 1.

[0041] Both the mounting block 10 and the mounting groove 13 are rectangular structures. The stability of the support part 2 can be improved by using the rectangular structure of the mounting block 10 and the mounting groove 13.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
