[0002] In the power industry, the quality inspection of single-phase electricity meters is an important link to ensure the accuracy and reliability of the electricity meters.

[0003] Traditional single-phase electricity meter testing is usually only carried out at the assembly stage, testing by connecting to a mainframe and using specific test voltages and electricity quantities. For the finished electricity meters after assembly, there are lack of effective quality verification means.

[0004] Furthermore, traditional testing methods cannot provide effective quality verification at the finished electricity meter stage, which may lead to potential quality problems being discovered only after the electricity meters are put into use, thus affecting the accuracy and reliability of the electricity meters. Utility Model Content

[0005] In order to facilitate the quality testing of single-phase electricity meters at the finished product stage, this application provides a single-phase electricity meter testing rack.

[0006] The single-phase electricity meter testing rack provided by this application adopts the following technical solutions:

[0007] A single-phase electricity meter testing rack includes a rack body. A fixing component for fixing the single-phase electricity meter on the rack body is arranged on the rack body. A tester for testing the single-phase electricity meter is arranged on the rack body. A testing mechanism for electrically connecting the tester and the single-phase electricity meter is arranged on the rack body. The testing mechanism includes:

[0008] A sliding block which is slidably arranged on the rack body along the direction close to or away from the single-phase electricity meter;

[0009] Pin feet. Multiple groups of pin feet are arranged on the sliding block and are electrically connected to the tester. The multiple groups of pin feet slide with the sliding block and are used for plugging into corresponding pin holes on the single-phase electricity meter;

[0011] By adopting the above technical solutions, the assembled single-phase electricity meter is placed on the rack body and positioned by the fixing component. Then, the driving component drives the sliding block to slide towards the direction close to the single-phase electricity meter. Finally, multiple groups of pin feet on the sliding block are inserted into corresponding pin holes on the single-phase electricity meter, enabling the electrical connection between the single-phase electricity meter and the tester, so as to facilitate the quality testing of single-phase electricity meters at the finished product stage.

[0012] Furthermore, the driving component includes:

[0020] Fixing bolts, the fixing bolts pass through the through holes and tightly press and lock the fixing blocks on the frame.

[0021] By adopting the above technical solution, the fixing bolts pass through the through holes and lock the fixing blocks on the frame. At the same time, the four groups of fixing blocks respectively tightly press on the four side walls of the single-phase electric meter, so as to fixedly install the single-phase electric meter on the frame.

[0022] Furthermore, the through holes are of a long strip structure, and the fixing bolts slide along the length direction in the through holes, so that the fixing blocks slide along the direction close to or away from the side walls of the single-phase electric meter.

[0023] By adopting the above technical solution, when the position of the fixing block needs to be adjusted, loosen the fixing bolts, and then move the fixing blocks, so that the fixing bolts slide along the length direction in the through holes.

[0026] A pressing block, which is slidably arranged on the frame along the direction of approaching or departing from the limiting block and is used to press the side wall of the single-phase electric meter on the side away from the limiting block;

[0027] A second driving member, which is arranged on the frame and is used to drive the pressing block to slide.

[0028] By adopting the above technical solution, the single-phase electric meter is placed in the specified area of the frame, and the two groups of second driving members respectively drive the two groups of pressing blocks to slide on the cover body, and the single-phase electric meter is pressed and fixed on the two groups of limiting blocks through the two groups of pressing blocks, so as to facilitate the rapid positioning of the single-phase electric meter.

[0029] Furthermore, rubber pads are arranged on the sides of the limiting block and the pressing block close to the side wall of the single-phase electric meter.

[0030] By adopting the above technical solution, when the limiting block or the pressing block approaches the single-phase electric meter, the rubber block presses against the single-phase electric meter, so as to reduce the probability of damaging the side wall of the single-phase electric meter.

[0031] Furthermore, the frame includes:

[0032] A box body, on which a placement groove for placing a detector is opened, and ventilation openings communicated with the placement groove are opened on the side wall of the box body;

[0048] Referring to Figure 1 and Figure 2, the frame body 1 is placed on the workbench. Inside the frame body 1, a tester 4 for testing single-phase electric meters is fixedly installed. To facilitate the installation or maintenance of the tester 4, the frame body 1 includes a box body 11, a cover body 12, and a support frame 13. The box body 11 is provided with a storage groove for placing the tester 4, and the tester 4 is fixedly installed in the storage groove. At the same time, a plurality of ventilation openings 111 communicating with the inside of the storage groove are provided on the side wall of the box body 11 to facilitate ventilation and heat dissipation of the tester 4; the cover body 12 is rotatably installed on the box body 11, and the cover body 12 is used to close the top of the box body 11. A display opening 121 for operating the display screen of the tester 4 is provided on the cover body 12; the support frame 13 is fixedly installed on the cover body 12, and the support frame 13 is perpendicular to the surface of the cover body 12. The support frame 13 is used to support and fix the testing mechanism 3.

[0049] Refer to Figure 1 and Figure 3 , the fixing component 2 is arranged on the upper surface of the cover body 12. The fixing component 2 is used to fix the single-phase electric meter on the upper surface of the cover body 12. The fixing component 2 includes a fixing block 21 and a fixing bolt 22. The fixing block 21 is a strip-shaped structure, and through holes 211 are provided at both ends in the length direction of the fixing block 21. The fixing bolt 22 passes through the through hole 211 and is threadedly installed on the cover body 12; four groups of fixing blocks 21 are provided, and all four groups of fixing blocks 21 are locked on the upper surface of the cover body 12 through the fixing bolts 22. The four groups of fixing blocks 21 enclose a receiving space for accommodating the single-phase electric meter. The four groups of fixing blocks 21 respectively press against and fix the bottom of the four side walls of the single-phase electric meter. The lengths of the four groups of fixing blocks 21 correspond to the widths of the corresponding side walls of the single-phase electric meter; to facilitate the adjustment of the position of the fixing block 21, the through hole 211 is set as a strip-shaped structure, and the length direction of the through hole 211 is parallel to the width direction of the fixing block 21; the fixing bolt 22 slides along the length direction in the through hole 211, so that the fixing block 21 slides along the direction close to or away from the side wall of the single-phase electric meter, thereby adjusting the position of the fixing block 21 to facilitate the fixing of single-phase electric meters of different sizes; at the same time, to increase the adjustment range of the position of the fixing block 21, a plurality of threaded holes threadedly connected to the fixing bolt 22 are installed at intervals on the cover body 12 along the sliding direction of the fixing block 21.

[0050] Refer to Figure 3 , when the position of the fixing block 21 needs to be adjusted, loosen the fixing bolt 22, and then move the fixing block 21, so that the fixing bolt 22 slides along the length direction in the through hole 211. When the fixing block 21 moves to the specified position, turn the fixing screw and press the fixing block 21 against the frame body 1, and finally the position of the fixing block 21 is adjusted.

[0051] Refer to Figure 1 and Figure 2, the test mechanism 3 includes a sliding block 31 and pins 32. The sliding block 31 is slidably mounted on the support frame 13 in a direction close to or away from the single-phase electric meter; the sliding direction of the sliding block 31 in this embodiment is parallel to the perpendicular line of the cover body 12; the pins 32 are fixedly mounted on the lower surface of the sliding block 31, and multiple groups of pins 32 are fixedly mounted on the sliding block 31. At the same time, multiple groups of pin holes are provided on the single-phase electric meter. The installation positions of the multiple groups of pins 32 on the sliding block 31 correspond one by one to the positions of the multiple groups of pin holes on the single-phase electric meter. The multiple groups of pins 32 are electrically connected to the tester 4 through multiple groups of cables. The multiple groups of pins 32 slide downward with the sliding block 31 and finally insert into the corresponding pin holes of the single-phase electric meter, so as to electrically connect the tester 4 to the single-phase electric meter; since the top of the single-phase electric meter is relatively high, in order to facilitate the sliding of the multiple groups of pins 32 with the sliding block 31 and insert them into the corresponding pin holes, an avoidance groove 311 for avoiding the top of the single-phase electric meter is provided on the sliding block 31. When the sliding block 31 slides in the direction close to the single-phase electric meter, the top of the single-phase electric meter is avoided through the avoidance groove 311, so that the multiple groups of pins 32 can be inserted into the corresponding pin holes.

[0052] Referring to Figure 1 and Figure 2 , the test mechanism 3 further includes a driving component 33. The driving component 33 includes a guiding column 331 and a first driving member 332. The guiding column 331 is fixedly mounted on the support frame 13. There are multiple groups of guiding columns 331, and the multiple groups of guiding columns 331 are spaced apart and mounted on the support frame 13. The sliding block 31 is slidably connected to the guiding column 331 to guide the sliding of the sliding block 31; the first driving member 332 is fixedly mounted on the support frame 13, and the movable end of the first driving member 332 is fixedly connected to the sliding block 31. When the first driving member 332 expands and contracts, it drives the sliding block 31 to slide on the guiding column 331; the first driving member 332 in this embodiment can be a linear driving mechanism such as a cylinder, a hydraulic cylinder or an electric push rod to achieve the same motion control function.

[0053] The working principle of Embodiment 1 of this application is as follows:

[0054] Place the assembled single-phase electric meter in the accommodating space surrounded by multiple fixing blocks 21 for positioning. Then, the first driving member 332 drives the sliding block 31 to slide in the direction close to the single-phase electric meter. Finally, the multiple groups of pins 32 on the sliding block 31 are inserted into the corresponding pin holes on the single-phase electric meter, so that the single-phase electric meter is electrically connected to the tester 4, so as to facilitate the quality test of the single-phase electric meter in the finished product stage.

[0055] Embodiment 2

[0056] Referring to Figure 4, The difference between this embodiment and Embodiment 1 is that there are two sets of fixing components 2. The fixing components 2 respectively press and fix the opposite side walls of the single-phase electric meter, and the two sets of fixing components 2 jointly press and fix the four side walls of the single-phase electric meter. The fixing component 2 includes a limiting block 23, a pressing block 24 and a second driving member 25. The limiting block 23 is fixedly installed on the upper surface of the cover body 12. The limiting block 23 is used to limit and fix the side wall of the single-phase electric meter. At the same time, a long strip through hole 211 for facilitating the adjustment of the position of the limiting block 23 on the cover body 12 is also opened on the limiting block 23. The limiting block 23 is threadedly installed on the upper surface of the cover body 12 through a bolt passing through the through hole 211. The pressing block 24 is slidably installed on the cover body 12 along the direction of approaching or departing from the limiting block 23. The pressing block 24 presses the side wall of the single-phase electric meter on the side far from the limiting block 23. The second driving member 25 is fixedly installed on the upper surface of the cover body 12. The movable end of the second driving member 25 is fixedly connected to the pressing block 24. The second driving member 25 is used to drive the pressing block 24 to slide on the cover body 12. Through the cooperation of the pressing block 24 and the limiting block 23, the opposite sides of the single-phase electric meter are pressed and fixed. The second driving member 25 in this embodiment can be one of linear driving mechanisms such as a cylinder, a hydraulic cylinder or an electric push rod.

[0057] Refer to Figure 4 , the two sets of limiting blocks 23 are perpendicular to each other. The two sets of limiting blocks 23 respectively limit and fix the adjacent side walls of the single-phase electric meter. The lengths of the two sets of limiting blocks 23 and the two sets of pressing blocks 24 correspond to the widths of the corresponding side walls of the single-phase electric meter.

[0058] Refer to Figure 4 , in order to reduce the probability of damage to the outer surface of the single-phase electric meter when pressing and fixing the single-phase electric meter, a rubber pad 5 is fixedly installed on the limiting block 23 and the pressing block 24 in the direction close to the side wall of the single-phase electric meter. When the limiting block 23 or the pressing block 24 approaches the single-phase electric meter, the rubber block presses against the single-phase electric meter, so as to reduce the probability of damage to the side wall of the single-phase electric meter.

[0059] Refer to Figure 4 , place the single-phase electric meter in the specified area on the cover body 12, and then start the two sets of second driving members 25 to drive the two sets of pressing blocks 24 to slide towards the single-phase electric meter, and finally press the single-phase electric meter against the two sets of limiting blocks 23 to accurately position the single-phase electric meter. At the same time, when the detection of the single-phase electric meter is completed, drive the pressing block 24 to slide away from the single-phase electric meter through the two sets of second driving members 25, so as to facilitate the removal of the detected single-phase electric meter.

[0060] The working principle of Embodiment 2 of this application is:

[0061] Two sets of second driving members 25 drive two sets of pressing blocks 24 to slide on the cover body 12 respectively, and press and fix the single-phase electric meter against two sets of limiting blocks 23, so as to quickly clamp and fix the single-phase electric meter. At the same time, after the detection is completed, the two sets of second driving members 25 drive the two sets of pressing blocks 24 to move away from the single-phase electric meter respectively, facilitating the removal of the single-phase electric meter, and finally realizing the rapid positioning of the single-phase electric meter.
