[0026] Embodiment 1

[0027] As Figures 1-5 shown: An interchangeability test device for the communication interface of an electricity consumption information collection terminal, including an interchangeability test box 1 for the communication interface of the electricity consumption information collection terminal. The bottom surface of the interchangeability test box 1 is fixedly installed with a box cover 12 through fixing screws 11. Support feet 13 are fixedly installed at the four corners of the bottom of the box cover 12. A display module 14 and a control panel 15 are arranged on the front side of the interchangeability test box 1. The box cover 12 is provided to facilitate the maintenance and management of the mechanisms inside the interchangeability test box 1;

[0028] The two sides of the interchangeability test box 1 are each provided with corresponding slots 2. Near the slots 2 on the top surface of the interchangeability test box 1, a positioning mechanism 3 is movably installed. The positioning mechanism 3 includes a positioning seat 31 movably installed on the inner top surface of the slot 2. At the center of the top surface of the positioning seat 31, a lifting rod 32 is fixedly connected. The top end of the lifting rod 32 is fixedly connected with a limiting rod 321, and the limiting rod 321 is located on the top surface of the interchangeability test box 1. A pull handle 322 is fixedly installed at the top end of the limiting rod 321. Springs 33 are movably installed around the lifting rod 32 on the top surface of the positioning seat 31. By providing the positioning mechanism 3, it is convenient to limit the plug of the electrical information acquisition terminal inserted into the slot 2. First, use the pull handle 322 to lift upward, drive the lifting rod 32 to slide upward through the limiting rod 321, and the positioning seat 31 also moves upward accordingly. At this time, the springs 33 are compressed. Pass the plug of the electrical information acquisition terminal through the inside of the slot 2 and plug it in. Subsequently, the positioning seat 31 automatically resets under the reaction force of the springs 33, and under its action, the plug of the electrical information acquisition terminal is fixedly limited to prevent detachment during the interchangeability test and maintain stability;

[0029] The inner wall of the interchangeability test box 1 is fixedly installed with a control module 4. An insertion mechanism 5 is arranged inside the interchangeability test box 1. Among them, the insertion mechanism 5 includes a U-shaped mounting frame 51 fixedly installed on the inner bottom surface of the interchangeability test box 1. An interchange detection module 52 is fixedly installed inside the U-shaped mounting frame 51. On both sides of the top of the interchange detection module 52, a first multi-interface structure 53 and a second multi-interface structure 54 are symmetrically distributed. Both the first multi-interface structure 53 and the second multi-interface structure 54 include an angle encoder servo motor 55 fixedly installed on the inner wall of the U-shaped mounting frame 51. The interchange detection module 52, the angle encoder servo motor 55, and the control module 4 are electrically connected. One end of the angle encoder servo motor 55 close to the slot 2 is movably installed with a cross 57 through a transmission shaft 56. The transmission shaft 56 and the angle encoder servo motor 55 are fixedly connected through a coupling. On the upper, lower, left, and right positions of the end face of the cross 57 away from the transmission shaft 56, communication interfaces 571 of different models are respectively embedded. The interchange detection module 52 and the communication interfaces 571 of different models are electrically connected. During switching, under the action of the angle encoder servo motor 55, the cross 57 can automatically switch to a communication interface of a model that can be aligned with the slot 2 every time it rotates 90 degrees. Thus, the cross 57 can rotate 0 degrees, 90 degrees, 180 degrees, and 270 degrees to switch the communication interfaces 571 of different models embedded in the upper, lower, left, and right positions of the end face of the cross 57 away from the transmission shaft 56, and can avoid misalignment during the switching process, effectively controlling any one of the communication interfaces 571 of different models to be accurately aligned with the slot 2, ensuring the smooth progress of the interchangeability test. At the same time, through the symmetrically distributed first multi-interface structure 53 and second multi-interface structure 54, the communication interfaces 571 corresponding to the slots 2 on both sides of the interchangeability test box 1 can be independently switched, facilitating free combination.

[0030] In addition, in this embodiment, please refer to Figure 5 , upper spring limit seats 331 and lower spring limit seats 332 are respectively embedded at the top and bottom of the spring 33. And by setting the upper spring limit seats 331 and lower spring limit seats 332, the stability of the spring 33 during compression and expansion can be ensured, avoiding bending, thus facilitating the stability of the positioning seat 31;

[0031] In addition, in this embodiment, please refer to Figure 2 , Figure 3 and Figure 4 , a bearing seat 561 is sleeved on the outer surface of the transmission shaft 56. The bearing seat 561 is fixedly connected to the side of the U-shaped mounting frame 51. By setting the bearing seat 561 to support the transmission shaft 56, its stable operation is facilitated, reducing mechanical loss.

[0032] The working principle and process of the present utility model are as follows:

[0033] First, start the operation of the servo motor 55 with an angle encoder according to the test requirements. Under the action of the servo motor 55 with an angle encoder, the cross 57 can rotate by 0°, 90°, 180°, or 270°, so as to switch the communication interface 571 embedded in the upper, lower, left, or right position on the end face of the cross 57 far from the transmission shaft 56 to the slot 2 and accurately align it with the slot 2.

[0034] Subsequently, pull upwards using the pull handle 322. Drive the lifting rod 32 to slide upwards through the limiting rod 321, and the positioning seat 31 also moves upwards accordingly. At this time, the spring 33 is compressed. Pass the plug of the electrical information acquisition terminal through the inside of the slot 2 and plug it into one of the switched communication interfaces 571. Subsequently, the positioning seat 31 automatically resets under the reaction force of the spring 33, and fixes and limits the plug of the electrical information acquisition terminal under its action. At the same time, the interchangeability detection module 52 can perform interchangeability tests on different models of communication interfaces 571. Under the action of the servo motor 55 with an angle encoder, every time the cross 57 rotates by 90°, it can automatically switch to a model of communication interface that can be aligned with the slot 2. Thus, the cross 57 can rotate by 0°, 90°, 180°, and 270° to switch the different models of communication interfaces 571 embedded in the upper, lower, left, and right positions on the end face of the cross 57 far from the transmission shaft 56, and can avoid misalignment during the switching process, effectively controlling any one of the different models of communication interfaces 571 to be accurately aligned with the slot 2, ensuring the smooth progress of the interchangeability test.
