This design significantly improves detection efficiency, reduces the complexity of manual operation, and ensures the accuracy and consistency of detection; a single reciprocating motion of the touch seat 3 can simultaneously activate multiple micro switches 6, realizing batch detection and significantly improving detection efficiency; the cooperation of the guide rail 5 and the drive mechanism 2 ensures that the movement trajectory of the touch seat 3 is stable and accurate, improving the accuracy of detection; the structural design of the fixed seat 4 and the guide rail 5 ensures the stability of the entire detection process and reduces errors caused by mechanical vibration or displacement; the automated reciprocating motion of the touch seat 3 is achieved through the drive mechanism 2, reducing manual intervention and improving the automation level of the detection process.

[0030] Furthermore, the number of fixing slots 41 on the fixing base 4 is multiple.

[0031] As described above, the mounting base 4 has multiple mounting slots 41, allowing multiple microswitches 6 to be installed on a single mounting base 4, further enhancing the batch processing capability of the inspection. This design enables the simultaneous testing of multiple microswitches 6 in a single inspection process, significantly improving inspection efficiency.

[0032] Furthermore, it also includes a base plate 1, on which the fixed seat 4, guide rail 5 and drive mechanism 2 are all mounted.

[0033] As described above, by setting the base plate 1, the fixed seat 4, guide rail 5, and drive mechanism 2 are uniformly installed on the base plate 1, improving the stability and integrity of the entire fixture. This design facilitates the installation, maintenance, and handling of the equipment, while ensuring the coordination and consistency between the components.

[0034] Furthermore, the fixing seat 4 is detachably installed on the base plate 1.

[0035] As described above, the mounting base 4 is detachably mounted on the base plate 1, allowing it to be replaced or adjusted as needed. This design improves the flexibility and versatility of the fixture, enabling it to adapt to the testing requirements of microswitches 6 of different specifications; furthermore, the mounting base 4 can be disassembled and reassembled in batches, greatly improving testing efficiency.

[0036] Furthermore, the fixing base 4 is also provided with a fixing cover plate, which is used to press the micro switch 6 tightly into the fixing groove 41.

[0037] As described above, by setting a fixed cover plate, the micro switch 6 is pressed tightly into the fixed groove 41, ensuring that the micro switch 6 will not loosen or shift during the testing process. This design improves the accuracy and reliability of the test and reduces errors caused by unstable installation.

[0038] Furthermore, the driving mechanism 2 includes a fixed frame 21, a drive motor 22, a drive rod 24, and a guide sleeve 23. The drive motor 22 and the guide sleeve 23 are mounted on the fixed frame 21. The drive rod 24 is slidably mounted on the guide sleeve 23. One end of the drive rod 24 is connected to the output shaft of the drive motor 22, and the other end of the drive rod 24 is connected to the touch seat 3.

[0039] As described above, the drive mechanism 2 includes a fixed frame 21, a drive motor 22, a drive rod 24, and a guide sleeve 23, ensuring that the trigger seat 3 can reciprocate stably on the guide rail 5. This design, through a precise mechanical structure, guarantees the motion accuracy and stability of the trigger seat 3, thereby improving the reliability and consistency of the detection.

[0040] Furthermore, it also includes a counter, which is connected to the drive mechanism 2 and is used to count the number of times the micro switch 6 is pressed.

[0041] As described above, by setting a counter, the number of times the micro switch 6 is pressed is counted in real time, and the data is transmitted to an external device. This design can automatically record detection data, reduce errors from manual statistics, and improve detection efficiency and data management capabilities.

[0042] Furthermore, the fixing base 4 is also provided with a pick-up and put-out notch that communicates with the fixing groove 41.

[0043] As described above, the mounting base 4 has a notch that communicates with the mounting slot 41, facilitating the installation and removal of the micro switch 6. This design simplifies the operation process and improves work efficiency, especially when the micro switch 6 needs to be replaced frequently.

[0044] Furthermore, the side wall of the fixing groove 41 is provided with an indicator mark. When the micro switch 6 is installed in the fixing groove 41, the micro switch 6 covers the indicator mark.

[0045] As described above, the side wall of the mounting slot 41 is provided with an indicator mark. When the micro switch 6 is installed in the mounting slot 41, the micro switch 6 obscures the indicator mark. This design ensures the accurate installation position of the micro switch 6 through visual cues, reducing detection errors caused by improper installation.

[0046] Furthermore, the material of the indicator is a reflective material.

[0047] As described above, the indicator signs are made of reflective material, ensuring clear visibility even in low-light conditions. This design further improves the ease and accuracy of installation, especially in environments with insufficient light.

[0048] Please refer to Figure 1 and Figure 2 Embodiment 1 of this utility model is as follows: a testing fixture for micro switches of an electricity meter, comprising a driving mechanism 2, a guide rail 5, an actuating seat 3, and at least two fixed seats 4; the fixed seat 4 is provided with a fixing groove 41 for mounting micro switches 6; the guide rail 5 is located between two adjacent fixed seats 4; the actuating seat 3 is slidably mounted on the guide rail 5, and the actuating seat 3 is provided with an actuating protrusion 31 corresponding to the position of the fixing groove 41; the driving mechanism 2 is used to drive the actuating seat 3 to reciprocate on the guide rail 5; it can be understood that by setting a reciprocating actuating seat 3 between two adjacent fixed seats 4, a single reciprocating motion of the actuating seat 3 can achieve the actuation test of at least two micro switches 6. This design significantly improves detection efficiency, reduces the complexity of manual operation, and ensures the accuracy and consistency of detection. A single reciprocating motion of the trigger seat 3 can simultaneously activate multiple microswitches 6, enabling batch detection and significantly improving detection efficiency. The cooperation between the guide rail 5 and the drive mechanism 2 ensures the stable and precise movement trajectory of the trigger seat 3, improving detection accuracy. The structural design of the fixed seat 4 and the guide rail 5 ensures the stability of the entire detection process, reducing errors caused by mechanical vibration or displacement. The drive mechanism 2 enables automated reciprocating motion of the trigger seat 3, reducing manual intervention and increasing the automation level of the detection process.

[0049] Optionally, the number of fixing slots 41 on the fixing base 4 can be set according to actual application requirements. In this embodiment, there are two fixing bases 4, and each fixing base 4 has multiple fixing slots 41. This allows multiple microswitches 6 to be installed on a single fixing base 4, further improving the batch processing capability of the detection. This design enables multiple microswitches 6 to be tested simultaneously in one detection process, significantly improving detection efficiency. Correspondingly, there are also multiple actuation protrusions 31 on the actuation base 3, and one actuation protrusion 31 corresponds to one fixing slot 41.

[0050] In addition, in some other embodiments, the number of fixing seats 4 can be three, four, five or more; more specifically, if the number of fixing seats 4 is N, then the number of trigger seats 3 is N-1; more specifically, when the number of fixing seats 4 is greater than or equal to three, the fixing slots 41 are provided on both sides of the fixing seat 4 between the two outermost fixing seats 4, thus simplifying the number of fixing seats 4.

[0051] Preferably, the testing fixture for the micro switch of the energy meter further includes a base plate 1. The fixing seat 4, guide rail 5, and drive mechanism 2 are all mounted on the base plate 1. It is understood that by setting the base plate 1, the fixing seat 4, guide rail 5, and drive mechanism 2 are uniformly mounted on the base plate 1, improving the stability and integrity of the entire fixture. This design facilitates the installation, maintenance, and handling of the equipment, while ensuring the coordination and consistency between the components. Optionally, the fixing seat 4 can be detachably mounted on the base plate 1, allowing it to be replaced or adjusted as needed. This design improves the flexibility and versatility of the fixture, enabling it to adapt to the testing requirements of microswitches 6 of different specifications. Furthermore, the microswitches 6 can be batch-assembled and disassembled by removing and installing the mounting base 4, greatly improving testing efficiency. In other words, during the testing process, the microswitches 6 can be pre-installed one-to-one on the mounting base 4. After the previous batch of microswitches 6 has been tested, the mounting base 4 with the tested microswitches 6 can be removed from the base plate 1, and the mounting base 4 with the untested microswitches 6 can be installed on the base plate 1, allowing the next round of testing to begin immediately, saving time on disassembling and assembling the microswitches 6.

[0052] Optionally, the mounting base 4 is further provided with a fixing cover (not shown in the figure). The fixing cover is detachably installed on the mounting base 4 and is used to press the micro switch 6 tightly into the fixing groove 41. By setting the fixing cover, the micro switch 6 is pressed tightly into the fixing groove 41, ensuring that the micro switch 6 will not loosen or shift during the testing process. This design improves the accuracy and reliability of the test and reduces errors caused by unstable installation. Further optionally, the fixing cover can be a transparent acrylic plate.

[0053] Preferably, the driving mechanism 2 includes a fixed frame 21, a drive motor 22, a drive rod 24, and a guide sleeve 23. The fixed frame 21 is detachably mounted on the base plate 1. The drive motor 22 and the guide sleeve 23 are mounted on the fixed frame 21. The drive rod 24 is slidably mounted on the guide sleeve 23. One end of the drive rod 24 is connected to the output shaft of the drive motor 22, and the other end of the drive rod 24 is connected to the touch seat 3. This ensures that the touch seat 3 can reciprocate stably on the guide rail 5. This design, through a precise mechanical structure, ensures the motion accuracy and stability of the touch seat 3, thereby improving the reliability and consistency of the detection. Optionally, a counter and a speed controller can also be installed on the base plate 1. The counter and the speed controller are both electrically connected to the drive motor 22 of the driving mechanism 2 to count the number of times the micro switch 6 is pressed, and the speed controller is used to adjust the speed of the drive motor 22.

[0054] In this embodiment, the drive motor 22 is a DC motor, and the fixed frame 21 is provided with a reduction gearbox 25. The power input end of the reduction gearbox 25 is connected to the output shaft of the drive motor 22, and the power output end of the reduction gearbox 25 is provided with a crank transmission mechanism 26, which is connected to the drive rod 24.

[0055] Optionally, the mounting base 4 is also provided with a pick-and-place notch (not shown) communicating with the mounting groove 41, which facilitates the installation and removal of the micro switch 6. This design simplifies the operation process and improves work efficiency, especially when the micro switch 6 needs to be replaced frequently.

[0056] Optionally, an indicator (not shown) can be provided on the side wall of the fixing groove 41. When the micro switch 6 is installed in the fixing groove 41, the micro switch 6 obscures the indicator. This design provides visual cues to ensure the accurate installation position of the micro switch 6 and reduces detection errors caused by improper installation. Further, the indicator can be made of reflective material, making it clearly visible even in low-light environments. This design further improves the convenience and accuracy of installation, especially in low-light conditions.
