[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, a lifting assembly is used to activate the electric push rod when the verification device is in use.

Simultaneously, it moves the main body of the verification device upward to the outside of the housing, where a battery pack on the housing provides power. When the device is no longer in use, the electric push rod is activated, causing the support plate and the main body of the verification device to move downward into the housing. This allows the main body of the verification device to be automatically raised outside the housing or lowered into the housing, improving the convenience of using the device.

[0016] In this invention, by adjusting the components and clamping components, when the verification device is no longer in use, the main body of the verification device is placed on the support plate. Then, the reduction motor is started. The reduction motor drives the two clamping components to move closer to each other through the first bevel gear, the second bevel gear, the bidirectional screw, and the two sliding blocks. When the two clamping components clamp the main body of the verification device, the clamping shell slides inside the fixed shell, and several springs are compressed. After the clamping structure is in place, the electric push rod is started, which drives the main body of the verification device to move down into the box through the support plate. During the movement of the device, the two clamping components clamp and fix the main body of the verification device to prevent the main body of the verification device from shaking and colliding with the inner wall of the box, which would cause damage to the main body of the verification device.

[0026] The adjustment assembly 3 includes a housing 301, a fixing block 302 installed on the inner wall of the housing 301, a reduction motor 303 installed at the rear end of the housing 301, a first bevel gear 304 installed at the output end of the reduction motor 303, a bidirectional screw 305 rotatably mounted through one side of the housing 301, a second bevel gear 306 installed on the outer wall of the bidirectional screw 305 near the middle, and a sliding block 307 threadedly mounted on the outer wall of the bidirectional screw 305.

[0027] The clamping assembly 5 includes a clamping block 501, a fixing shell 502 is installed on one side of the clamping block 501, a clamping shell 503 is slidably installed on the inner wall of the fixing shell 502, a number of evenly distributed springs 504 are installed on one side of the inner wall of the clamping shell 503, and an anti-slip rubber pad 505 is installed on one side of the clamping shell 503.

[0028] In this embodiment, as Figure 2 As shown, the protective box assembly 1 includes a box body 101. A cover plate 102 is installed on the top of the box body 101 via a hinge. Handles 103 are installed on both sides of the box body 101. When the cover plate 102 is closed with the box body 101, the lock on the cover plate 102 is inserted into the lock body on the box body 101. The two handles 103 facilitate the movement of the verification device.

[0029] In this embodiment, as Figure 3As shown, the first slide rail 201, electric push rod 202, and first support block 203 are all installed on the bottom of the inner wall of the housing 101. The second T-shaped slider 2014 is slidably installed in the second track 2015. The middle of the first support column 207 and the second support column 2012 are rotatably connected by a plug rod. The mounting block 204 is rotatably installed on the outer wall of the first connecting rod 206. When the electric push rod 202 is started, it drives the first connecting rod 206 to move left and right through the mounting block 204. The first connecting rod 206 then drives the first T-shaped slider 2014 to move left and right. 05 moves left and right within the first slide rail 201. At the same time, the first T-shaped slider 205 drives the support plate 2010 to move up and down through the first connecting rod 206, the first support column 207, the second support block 209, the second support column 2012, the second T-shaped slider 2014, and the second track 2015. This can drive the main body 4 of the calibration device to move up and down, automatically drive the main body 4 of the calibration device into the housing 101, or automatically lift the main body 4 of the calibration device to the outside of the housing 101, improving the convenience of using the device.

[0030] In this embodiment, as Figure 3 As shown, the first slide rail 201, the first support block 203, the first T-shaped slider 205, the first support column 207, the second support block 209, the second support column 2012, the second T-shaped slider 2014, and the second track 2015 are symmetrically distributed about the vertical center line of the support plate 2010. When the electric push rod 202 is activated and drives the first connecting rod 206 to move left and right through the mounting block 204, the support plate 2010 is moved up and down through the two sets of first slide rails 201, first support block 203, first T-shaped slider 205, first support column 207, second support block 209, second support column 2012, second T-shaped slider 2014, and second track 2015, which can improve the stability of the main body 4 of the calibration device when it moves up and down.

[0031] In this embodiment, as Figure 3 and Figure 4 As shown, the housing 301 is mounted on the top of the support plate 2010, and the sliding blocks 307 are slidably mounted on the inner wall of the housing 301. The sliding blocks 307 are symmetrically distributed about the vertical center line of the bidirectional screw 305. The first bevel gear 304 and the second bevel gear 306 are meshed together. When the reduction motor 303 starts, the first bevel gear 304 drives the second bevel gear 306 and the bidirectional screw 305 to rotate. When the bidirectional screw 305 rotates, the distance between the two sliding blocks 307 can be adjusted, thereby adjusting the distance between the two clamping components 5. This allows for clamping of the verification device body 4, facilitating the installation and disassembly of the verification device body 4 as needed. At the same time, when moving the device, this improves the stability of the verification device body 4 within the housing 101, preventing the verification device body 4 from colliding with the interior of the housing 101 and causing damage to the verification device body 4.

[0032] In this embodiment, as Figure 4 As shown, a circular hole with an inner diameter larger than the outer diameter of the bidirectional screw 305 is provided on one side of the fixing block 302, and the fixing blocks 302 are symmetrically distributed about the vertical center line of the bidirectional screw 305. The two fixing blocks 302 can limit the sliding block 307 to prevent the sliding block 307 from colliding with the first bevel gear 304 or the second bevel gear 306 when the two sliding blocks 307 are close to each other, which would cause damage to the device.

[0033] In this embodiment, as Figure 4 and Figure 5 As shown, the clamping block 501 is installed at the front end of the sliding block 307, and one end of the spring 504 is installed on one side of the inner wall of the fixed shell 502. The clamping components 5 are symmetrically distributed about the vertical center line of the shell 301. When the two clamping components 5 are driven to move closer to each other by the adjusting component 3, the two clamping components 5 clamp the main body 4 of the verification device. The clamping shell 503 slides in the fixed shell 502, and several springs 504 are compressed, which can elastically clamp the main body 4 of the verification device and improve the stability during clamping.

[0034] The method of use and advantages of this utility model: The calibration device for insulation detection in IT AC systems operates as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, first open the cover plate 102, then control the electric push rod 202 to start via the control button on the left side of the housing 101. The electric push rod 202 drives the support plate 2010 upward through the mounting block 204, the first connecting rod 206, the first T-shaped slider 205, the first support column 207, the second support block 209, the second support column 2012, the second T-shaped slider 2014, and the second track 2015. At the same time, it drives the main body 4 of the calibration device upward to the outside of the housing 101, so that the main body 4 of the calibration device can be used. When it is necessary to remove the main body 4 of the calibration device for use, start the reduction motor 303, which drives the first bevel gear 304, the second bevel gear 306, and the bidirectional screw. 305 and two sliding blocks 307 drive the two clamping components 5 away from each other. Then, the main body 4 of the calibration device is removed. When the main body 4 of the calibration device is finished, it is placed on the support plate 2010. Then, the reduction motor 303 is started. Through the first bevel gear 304, the second bevel gear 306, the bidirectional screw 305 and the two sliding blocks 307, the two clamping components 5 are driven to move closer to each other. The two clamping components 5 clamp the main body 4 of the calibration device. The clamping shell 503 slides in the fixed shell 502. Several springs 504 are compressed. Then, the electric push rod 202 is started. Through the support plate 2010, the main body 4 of the calibration device is moved down into the box 101. Then, the cover plate 102 is closed.
