[0028] See also Figures 1 to 3 ,as well as Figures 7 to 10The utility model provides a guide rail type dual-circuit DC electric energy meter automatic calibration auxiliary device 100, comprising a bottom plate 10, a first terminal head 20 for contacting and cooperating with a first circuit side 210 of a first type electric energy meter 200, a second terminal head 30 for contacting and cooperating with a second circuit side 220 opposite to the first type electric energy meter 200, a first driver 40a for driving the first terminal head 20 to contact or separate with the first circuit side 210 of the first type electric energy meter 200, a second driver 40b for driving the second terminal head 30 to contact or separate with the second circuit side 220 of the first type electric energy meter 200, and a first spanning across the first terminal head 20. The present invention relates to a first embodiment of the present invention, wherein the first embodiment comprises a first terminal head 70 for contacting and cooperating with the first circuit side 230 of the second type of electric energy meter 200', a second cross frame 50b for crossing over the second terminal head 30, a placement frame 60 for placing the second type of electric energy meter 200', a third terminal head 70 for contacting and cooperating with the first circuit side 230 of the second type of electric energy meter 200', a fourth terminal head 80 for contacting and cooperating with the second circuit side 240 opposite to the second type of electric energy meter 200', a third driver 90a for driving the third terminal head 70 to contact or separate with the first circuit side 230 of the second type of electric energy meter 200', and a fourth driver 90b for driving the fourth terminal head 80 to contact or separate with the second circuit side 240 of the second type of electric energy meter 200'. The fourth driver 90b is located above the second driver 40b, and the third driver 90a is located above the first driver 40a. Optionally, as an example, the first driver 40a, the second driver 40b, the third driver 90a and the fourth driver 90b are all air cylinders or oil cylinders, etc., but are not limited thereto.

[0029] At the same time, the first terminal head 20 is arranged opposite to the second terminal head 30 along the length direction of the bottom plate 10, and the state is shown in FIG. Figure 2 and Figure 3 Obviously, according to actual needs, the first terminal head 20 can also be arranged opposite to the second terminal head 30 along the width direction of the bottom plate 10, so it is not necessary to Figure 2 and Figure 3 in addition, the third terminal head 70 is located above the first terminal head 20, and the fourth terminal head 80 is located above the second terminal head 30.

[0030] Furthermore, the first cross frame 50a and the second cross frame 50b are located above the bottom plate 10 and assembled on the bottom plate 10, and the bottom plate 10 provides support for the first cross frame 50a and the second cross frame 50b; Figure 2 and Figure 3 As an example, the first cross frame 50a and the second cross frame 50b are arranged spaced apart along the length direction of the base plate 10, that is, the spacing direction between the first cross frame 50a and the second cross frame 50b is consistent with the relative direction between the first terminal head 20 and the second terminal head 30.

[0031] In addition, the bottom plate 10 is provided with an extension rail 11 located between the first cross frame 50a and the second cross frame 50b and extending along the width direction of the bottom plate 10, that is, the extension direction of the extension rail 11 is consistent with the relative direction between the first terminal head 20 and the second terminal head 30; the placement frame 60 is detachably slidably arranged on the extension rail 11, so that the placement frame 60 can be flexibly installed at the extension rail 11 according to actual needs, or removed from the extension rail 11, so as to meet the use needs of the second type electric energy meter 200' or the first type electric energy meter 200 accordingly. More specifically, as follows:

[0032] like Figures 1 to 3 As shown, as an example, the bottom plate 10 is further provided with a first guide rail 12 spanned by a first cross frame 50a and perpendicular to the extension guide rail 11, and a second guide rail 13 spanned by a second cross frame 50b and perpendicular to the extension guide rail 11; the first terminal head 20 is slidably arranged on the first guide rail 12, so that the sliding of the first terminal head 30 is more stable and smoother; the second terminal head 30 is slidably arranged on the second guide rail 13, so that the sliding of the second terminal head 40 is more stable and smoother. Specifically, Figure 4 As an example, both ends of the first guide rail 12 extend out of the first cross frame 50a, and both ends of the second guide rail 13 extend out of the second cross frame 50b. This design not only meets the sliding travel requirements of the first terminal head 20 and the second terminal head 30, but also facilitates the assembly and disassembly operations of the first terminal head 20 and the second terminal head 30 on the bottom plate 10. More specifically, Figure 2 and Figure 3 As an example, the first guide rail 12 and the second guide rail 13 are aligned in a straight line; obviously, according to actual needs, the first guide rail 12 and the second guide rail 13 may also be staggered from each other. Figure 2 and Figure 3 Limits shown.

[0033] like Figures 1 to 3 As shown, as an example, the first cross frame 50a is provided with a third guide rail 51 which is located above the first guide rail 12 in parallel, and the third terminal head 70 is slidably arranged on the third guide rail 51 to improve the stability and smoothness of the sliding of the third terminal head 70; the second cross frame 50b is provided with a fourth guide rail 52 which is located above the second guide rail 13 in parallel, and the fourth terminal head 80 is slidably arranged on the fourth guide rail 52 to improve the stability and smoothness of the sliding of the fourth terminal head 80; optionally, Figures 1 to 3As an example, the first cross frame 50a and the second cross frame 50b are each in the shape of a "door", so as to facilitate the assembly operation of the first cross frame 50a and the second cross frame 50b with the base plate 10 respectively, and also facilitate the first cross frame 50a to surround the first terminal head 20, the first driver 40a, the third terminal head 70 and the third driver 90a from all sides to achieve a protective effect; similarly, it is also convenient for the second cross frame 50b to surround the second terminal head 30, the second driver 40b, the fourth terminal head 80 and the fourth driver 90b from all sides to achieve a protective effect.

[0034] Combination Figures 2 to 3 As an example, the first terminal head 20 has two terminal rows 21 that are spaced apart and aligned along the extension direction of the extension guide rail 11, so that when the first terminal head 20 is in contact with the first circuit side 210 of the first model electric energy meter 200, a circuit can be formed between the two terminal rows 21 and the first model electric energy meter 200; the second terminal head 30 has two terminal rows 31 that are spaced apart and aligned along the extension direction of the extension guide rail 11, so that when the second terminal head 30 is in contact with the second circuit side 220 of the first model electric energy meter 200, another circuit can be formed between the two terminal rows 31 and the first model electric energy meter 200.

[0035] Recombination Figure 2 and Figure 3 The third terminal head 70 has two terminal rows 71 that are separated from each other along the extension direction of the extension guide rail 11 and the up-down direction of the base plate 10, that is, in the two terminal rows 71, their positions are separated from each other in the extension direction of the extension guide rail 11 and the up-down direction of the base plate 11, so that when the third terminal head 70 contacts and cooperates with the first circuit side 230 of the second model electric energy meter 200`, a circuit can be formed between the two terminal rows 71 and the second model electric energy meter 200`; the fourth terminal head 80 has two terminal rows 81 that are separated from each other along the extension direction of the extension guide rail 11 and the up-down direction of the base plate 10, so that when the fourth terminal head 80 contacts and cooperates with the second circuit side 240 of the second model electric energy meter 200`, another circuit can be formed between the two terminal rows 81 and the second model electric energy meter 200`.

[0036] like Figures 1 to 3As shown, the first driver 40a and the third driver 90a are both fixed to the first cross frame 50a, and the first cross frame 50a provides support for the first driver 40a and the third driver 90a; the second driver 40b and the fourth driver 90b are both fixed to the second cross frame 50b, and the second cross frame 50b provides support for the second driver 40b and the fourth driver 90b. Obviously, according to actual needs, one of the first driver 40a and the third driver 90a can be installed in the first cross frame 50a, and the other can be installed on the bottom plate 10, or the first driver 40a and the third driver 90a can be installed on the bottom plate 10; similarly, one of the second driver 40b and the fourth driver 90b can be installed in the second cross frame 50b, and the other can be installed on the bottom plate 10, or the second driver 40b and the fourth driver 90b can be installed on the bottom plate 10; so it is not necessary to Figures 1 to 3 Limits shown.

[0037] like Figure 2 As shown, the bottom plate 10 is also provided with a positioning structure 14 located beside the end of the extension guide rail 11 along the extension direction of the extension guide rail 11, and the positioning structure 14 protrudes upward from the bottom plate 10; with the help of the positioning structure 14, the first type of electric energy meter 200 or the placement rack 60 that slides on the extension guide rail 11 can be laterally positioned to ensure the accuracy of the first terminal head 20 contacting and fitting the first circuit side 210 of the first type of electric energy meter 200, and the accuracy of the second terminal head 30 contacting and fitting the second circuit side 220 of the first type of electric energy meter 200; or, ensure the accuracy of the third terminal head 70 contacting and fitting the first circuit side 230 of the second type of electric energy meter 200' on the placement rack 60, and the accuracy of the fourth terminal head 80 contacting and fitting the second circuit side 240 of the second type of electric energy meter 200' on the placement rack 60. In addition, in combination with Figure 5 and Figure 6 As an example, the placement rack 60 is in the shape of a "コ", which effectively plays the role of raising the second type of electric energy meter 200' and reducing the amount of material used by the placement rack 60; the upper side of the placement rack 60 is provided with a matching guide rail 61 parallel to and matching the extension guide rail 11, so as to facilitate the installation and removal operation of the second type of electric energy meter 200' at the placement rack 60; optionally, Figure 5 and Figure 6 As an example, the placement rack 60 also has a blocking structure 62 located next to the end of the matching rail 61, and the blocking structure 62 blocks the second type of electric energy meter 200' which is slidably mounted on the matching rail 61. Figure 5 shown.

[0038] Compared with the prior art, the guide rail type dual-circuit DC electric energy meter automatic calibration auxiliary device 100 of the utility model can meet the use requirements of the first type electric energy meter 200 and the second type electric energy meter 200', so that the guide rail type dual-circuit DC electric energy meter automatic calibration auxiliary device 100 of the utility model has good generality. When the first type electric energy meter 200 is used, Figure 1 The placement rack 60 is removed from the base plate 10, and the first type electric energy meter 200 is slid onto the extension guide rail 11 until the first type electric energy meter 200 is positioned with the positioning structure 14; at this time, the first driver 40a drives the first terminal head 20 to slide to a position in contact with the first circuit side 210 of the first type electric energy meter 200, and the second driver 40b drives the second terminal head 30 to slide to a position in contact with the second circuit side 220 of the first type electric energy meter 200, so as to meet the testing needs of the first type electric energy meter 200. When the second type of electric energy meter 200' is used, the first type of electric energy meter 200' is removed from the extension rail 11, and the placement rack 60 with the second type of electric energy meter 200' is reinstalled on the extension rail 11 until the placement rack 60 is positioned with the positioning structure 14; at this time, the third driver 90a drives the third terminal head 70 to slide to a position in contact with the first circuit side 230 of the second type of electric energy meter 200', and the fourth driver 90b drives the fourth terminal head 80 to slide to a position in contact with the second circuit side 240 of the second type of electric energy meter 200', so as to meet the test needs of the second type of electric energy meter 200'. Therefore, the placement rack 60 is folded to match the use needs of the first type of electric energy meter 200 or the second type of electric energy meter 200'.

[0039] It is worth noting that the direction indicated by arrow A in the drawings and the opposite direction are the length direction of the bottom plate 10, the direction indicated by arrow B in the drawings and the opposite direction are the width direction of the bottom plate 10, and the direction indicated by arrow C in the drawings is the bottom-to-top direction of the bottom plate 10. In addition, the second type of electric energy meter 200' on the placement rack 60 can be completed before the placement rack 60 slides on the extension guide rail 11, and can also be completed after the slide is on the extension guide rail 11. In addition, the extension guide rail 11 and the first guide rail 12 to the fourth guide rail 52 are all trapezoidal guide rails, but are not limited thereto.

[0040] The above disclosure is only a preferred example of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
