[0037] In view of the technical problems recorded in the background technology, such as Figure 1-13As shown, a test fixture for an electric meter is provided, comprising: a box body 1, a base plate 2 is provided in the box body 1, and limit bars 3 for limiting the electric meter are provided on both sides of the base plate 2; a movable door 4, the movable door 4 is arranged on the box body 1, and the movable door 4 includes a guide rail 5 arranged on the box body 1, a slider 6 arranged on the guide rail 5, a cylinder 7 arranged on one side of the guide rail 5 and a door body 8 connected to the slider 6; wherein, the telescopic end of the cylinder 7 is connected to the door body 8, and the cylinder 7 drives the door body 8 to move along the guide rail 5 to open the box body 1; a telescopic part 9, the telescopic part 9 is installed on the base plate 2, and the telescopic end of the telescopic part 9 is provided with a detachably connected upper test needle plate 10, and the upper test needle plate 10 is used for connecting to the electric meter for testing; a lower test needle plate 11, the lower test needle plate 11 is arranged below the upper test needle plate 10, and the lower test needle plate 11 is used for connecting to the electric meter for testing.

[0038] There is an installation space inside the box body 1, and the front position of the box body 1 is used to install a movable door 4. During implementation, guide rails 5 are set on both sides of the box body 1, and sliders 6 are set on the guide rails 5. The sliders 6 are connected to the door body 8, and a cylinder 7 is set to connect with the door body 8. The cylinder 7 can be a rodless cylinder 7. When driving, the telescopic end of the cylinder 7 drives the door body 8 to extend and retract along the direction of the guide rail 5, so as to open or close the box body 1.

[0039] The specific usage process is: Figure 14-15 For the structure of the electric meter to be tested, the electric meter is manually placed between the limit bars 3 for limit fixing, the cylinder 7 drives the door body 8 to move and close along the guide rail 5, and the telescopic part 9 drives the upper test needle plate 10 to move toward the lower test needle plate 11. The upper test needle plate 10 and the lower test needle plate 11 are connected to the electric meter for testing. Among them, the telescopic part 9 can adopt a component with telescopic function such as the cylinder 7, and the upper test needle plate 10 and the lower test needle plate 11 are connected to the external high-voltage tester.

[0040] By adopting the above technical solution, detection is carried out in the closed box 1, thereby improving safety and optimizing the structural design.

[0041] like Figure 8-13As shown, the lower test needle plate 11 includes a base 12, a movable plate 13 installed on the base 12, and a guide block 14 arranged above the movable plate 13; the movable plate 13 has two or more mounting holes 15, and the mounting holes 15 are provided with screws 16 to connect with the base 12, and the aperture of the mounting holes 15 is larger than the outer diameter of the screws 16. A test needle is installed on the movable plate 13, and the guide block 14 is connected to the movable plate through two or more elastic guide columns 17. The guide block 14 has a guide groove 18 for guiding the detection position of the electric meter, and the guide groove 18 is provided with a pinhole 19 corresponding to the test needle.

[0042] During the production process, two similar electric meters were produced, and the detection position at the bottom of the meter had a deviation of several millimeters. To avoid the disassembly and replacement of the lower test needle plate 11, a movable structure was set on the lower test needle plate 11. The movable plate 13 and the base 12 are connected by four screws 16. The height of the screws 16 is set according to the thickness of the movable plate 13. The screws 16 are used to limit the Z direction of the movable plate 13. The mounting hole 15 on the movable plate 13 is set to be larger than the outer diameter of the screw 16. That is, there is a gap between the mounting hole 15 and the screw 16. This gap is used to achieve fine adjustment in the X and Y directions. The guide block 14 is connected by four elastic guide pillars 17.

[0043] The specific usage process is that under the drive of the telescopic part 9, the electric meter is driven to move downward, and the detection position below the electric meter is in the guide groove 18, and the guide groove 18 is used for positioning. Since the guide block 14 and the movable plate 13 are in an integrated form, they are automatically adapted, and the movable plate 13 is automatically adjusted in the X and Y directions, and then the guide block 14 is further compressed under the elastic guide column 17, and the test needle on the movable plate 13 is connected to the electric meter through the pinhole 19 of the guide groove 18 for testing.

[0044] The above technical solution has good adaptability, and the lower test needle plate 11 is moved for adaptation, thereby reducing the replacement steps of the lower test needle plate 11 and saving time.

[0045] Specifically, the guide groove 18 is provided with a guide slope 20 at the notch position. The guide slope 20 is provided to facilitate the detection position below the electric meter to enter the guide groove 18 for positioning.

[0046] As a preferred technical solution, the present invention further comprises a stamping member 21 provided on one side of the lower test needle plate 11 , and the stamping member 21 stamps detection characters on the electric meter.

[0047] The stamping piece 21 is used to mark the meter after the high voltage test.

[0048] In practice, the substrate 2 is arranged at an angle.

[0049] The present invention further includes a support plate 22 for supporting the substrate 2 , and the support plate 22 is connected to the substrate 2 and the back of the box 1 .

[0050] The present invention also includes a buzzer 23 installed in the box 1. The buzzer 23 is provided to prompt the detection of the electric meter or the failure of the equipment. For example, the buzzer 23 can be designed to be short and long beeps through programming.

[0051] As a preferred technical solution, the present invention includes two driving buttons 24 mounted on the housing 1. The two driving buttons 24 are pressed to drive the jig. In practice, the driving method is to press both driving buttons 24 simultaneously, which can avoid manual operation of the jig.

[0052] Furthermore, a reset button 25 is mounted on the housing 1, and the reset button 25 resets the jig by pressing it. The reset button 25 is used to restore the components to their original state when the jig fails to operate.

[0053] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
