[0002] At present, the accuracy detection production lines for domestic electric energy metering products are all dedicated lines, that is, a special detection line is required for detecting a certain type of electric energy metering product. There are many existing electric energy metering products, such as single-phase electric energy meters, three-phase direct-connection electric energy meters, three-phase mutual-induction electric energy meters, terminals, etc. Therefore, metering detection institutions need to purchase multiple detection production lines for detection. At the same time, since the products detected by different production lines are not compatible, when the demand for a single metering product is large during a certain period, other production lines cannot be used for detection, resulting in low equipment utilization rate and low detection efficiency.

[0030] In order to better explain the present invention for easy understanding, the following will describe the present invention in detail through specific embodiments with reference to the drawings.

[0031] It should be noted that all directional indications in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0032] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0033] In the present utility model, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] The present utility model provides a calibration tray for an electric energy metering product, as Figure 1 shown, which includes a support plate 10 for supporting the metering product. A limiting mechanism 20 is arranged on the support plate 10. The limiting mechanism 20 limits the electric energy metering product to be calibrated to ensure the stability of the electric energy metering product during the calibration process. A special electrical interface 30 matching the electric energy metering product is arranged on the support plate 10. The special electrical interface 30 is connected to the electric energy metering product to realize the calibration of the metering product. A general electrical interface 40 electrically connected to the special electrical interface 30 is arranged on one side of the support plate 10.

[0035] Specifically, in order to ensure that the electric energy metering product can be stably placed on the support plate 10, the limiting mechanism 20 includes an elastic limiting block 21 and a fixed limiting block 22. The elastic limiting block 21 is connected to the support plate 10 through a spring, and the fixed limiting block 22 is fixedly connected to the support plate 10 by bolts. In this embodiment, the elastic limiting block 21 is arranged opposite to the special electrical interface 30, so the elastic limiting block 21 limits the end of the electric energy metering product, and the fixed limiting block 22 limits the side of the electric energy metering product.

[0036] Further, before placing the electric energy metering product on the support plate 10, first push the elastic limit block 21 to make it lower than the surface of the support plate 10. After placing the electric energy metering product, at this time, the elastic limit block 21 bounces up under the action of the spring to limit the end face of the electric energy metering product, and the fixed limit block 22 limits the side face of the electric energy metering product. When the verification is completed, press the elastic limit block 21 again to take out the electric energy metering product.

[0037] Embodiment 1:

[0038] As Figure 1 shown, it further includes a base 50. Two inclined support plates 10 are symmetrically arranged on the base 50. An opening is provided on the base 50, which can facilitate stacking and storing multiple trays. During the stacking process, the lower support plate 10 passes through the upper base 50 through the opening and fits with the upper support plate 10 to achieve stacking. Universal electrical interfaces 40 are provided at positions corresponding to the dedicated electrical interfaces 30 on the base 50, which can facilitate verification on both sides of the base 50 simultaneously, improving work efficiency.

[0039] Embodiment 2:

[0040] As Figure 2 shown, it includes a bottom plate 51. Support plates 10 are arranged in parallel on the bottom plate 51. Universal electrical interfaces 40 are symmetrically arranged between the bottom plate 51 and the support plates 10. Since the bottom plate 51 and the support plates 10 are arranged in parallel, it can facilitate the smooth stacking of trays, convenient for transportation and storage, and has a simple structure and low cost.

[0041] Embodiment 3:

[0042] As Figure 3 shown, it includes a fixing plate 52. The support plate 10 is rotatably installed on the fixing plate 52 through a hinge 53. An angle adjusting device is arranged between the support plate 10 and the fixing plate 52 to change the angle between the support plate 10 and the fixing plate 52.

[0043] Specifically, the angle adjusting device includes a worm 54. The worm 54 is rotatably installed on the fixing plate 52. A worm gear 55 cooperating with the worm 54 is fixedly installed on the support plate 10. The worm gear 55 is coaxially arranged with the hinge 53. When the worm 54 rotates, at this time, the worm gear 55 rotates, and the worm gear 55 drives the support plate 10 to rotate around the hinge 53, thereby changing the angle between the support plate 10 and the fixing plate 52, which can adapt to different situations and has a wider range of use. When stacking and storing, the support plate 10 can be turned downward to make the support plate 10 and the fixing plate 52 misaligned, thereby reducing its height and enabling more trays to be stacked at one time.

[0044] Embodiment 4:

[0045] As shown Figure 4 in Figure 4 , two General Electric interfaces 40 are symmetrically arranged on the top surface of the support plate 10. Since two General Electric interfaces 40 are arranged on the top surface of the electrical structure 40, verification can be carried out simultaneously from both sides, greatly improving the work efficiency.

[0046] Specifically, in order to ensure a wider applicability of the tray, the General Electric interface is divided into a weak point interface and a strong power interface, and the strong power interface is 12-pin or 24-pin.

[0047] The present invention also provides an apparatus for verifying an electric energy metering product, as shown Figure 5 in Figure 6 Figure 6 and , which includes a conveying rack 60. On both sides of the conveying rack 60, power connection devices 70 are symmetrically arranged. The above-mentioned tray is arranged on the conveying rack 60, and the power connection device 70 is docked with the General Electric interface 40 on the tray to realize power supply to the tray, so as to detect the electric energy metering product. A lifting structure 61 and a lifting blocking mechanism 62 are arranged at positions corresponding to the power connection device 70 on the conveying rack 60.

[0048] Specifically, the tray is transported on the conveying rack 60. In this embodiment, the tray is always installed on the conveying rack 60. The manipulator grabs the electric energy metering product and installs it on the tray, and then the conveying rack 60 transports the tray with the installed electric energy metering product to the power connection device 70 for verification. During the process of transporting the tray, first, the lifting blocking mechanism 62 rises to block and stop the tray, and then the lifting mechanism 61 rises to align the General Electric interface 40 on the tray with the power connection device 70. Then, the power connection device 70 is connected to the General Electric interface 40 to realize verification of the electric energy metering product. After the verification is completed, the manipulator removes the electric energy metering product again. In order to improve the verification efficiency, multiple pairs of power connection devices 70 can be arranged on the conveying rack 60 for simultaneous verification.

[0049] As shown Figure 7 in Figure 8 Figure 7 and Figure 8 , the power connection device 70 includes a base 71. Two parallel slide rails 72 are arranged on the base 71. A housing 73 is slidably installed on the slide rails 72. A cylinder 74 is arranged between the housing 73 and the base 71. The cylinder 74 is used to push the housing 73 to move along the slide rails 72. A General Electric power-on interface 75 that cooperates with the General Electric interface 40 is installed on the housing 73. In order to ensure that the General Electric power-on interface 75 can be smoothly docked with the General Electric interface 40, a positioning pin 76 is arranged on the General Electric power-on interface 75, and a positioning hole 77 that cooperates with the positioning pin 76 is arranged on the General Electric interface 40.

[0050] It should be understood that the above description of the specific embodiments of the present utility model is only for explaining the technical route and features of the present utility model, and its purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly.
