[0002] A withstand voltage tester, also known as a voltage tester, is an instrument used to measure the voltage withstand capacity of electrical equipment, insulating materials, etc. Its working principle is to apply a certain high voltage to both ends of the object being tested, and judge its insulation withstand voltage quality by detecting the insulation performance of the object being tested under the high voltage, such as whether breakdown, leakage, etc. occur. A withstand voltage tester calibration device is a device for calibrating the data of the withstand voltage tester. The heat dissipation holes of the existing withstand voltage tester calibration device are not easy to protect, which leads to dust entering the heat dissipation holes and accumulating after long-term use, thereby damaging the internal components.

[0003] In response to the above problem, regarding the technical problem that the heat dissipation holes of the existing withstand voltage tester calibration device are not easy to protect, which leads to dust entering the heat dissipation holes and accumulating after long-term use, thereby damaging the internal components, after a lot of searches, a portable withstand voltage tester calibration device with patent publication number CN220983482U was found, which belongs to the field of portable withstand voltage tester calibration devices. The device can press the protective component to detach the protective component from the box, and then pull the protective component to fold the protective component, so that the user can start the main body. After that, the heat dissipation holes of the main body can be exposed by pushing the arc block, which can facilitate heat dissipation when the main body is working. When the arc block is pushed down, the heat dissipation holes of the main body can be protected to prevent dust from entering the heat dissipation holes and causing damage to the internal components. After the main body is used, the top of the protective component can be brought into contact with the inner wall of the box, and then the protective component can be pressed to engage with the box, thereby protecting the display panel of the main body to prevent accidental touch and collision from causing damage to the display panel of the main body.

For example, the connection and fixing method between the snap block and the snap slot is unstable, which can easily cause inconvenience in using the device. To address these issues, the present invention proposes a portable voltage withstand tester calibration device. Utility Model Content

The limiting mechanism 5 includes a limiting block 57, which is movably arranged between the box body 1 and the socket 7 and is configured to limit the limiting hole 10. The end of the limiting block 57 away from the socket 7 is fixedly connected to a driving Rod 54, the driving rod 54 is movably arranged in the box body 1, the rotating shaft 52 is rotatably arranged on the box body 1, and a turntable 51 is sleeved on the rotating shaft 52.

[0027] Specifically, when it is necessary to close the box door 4 to protect the tester body 6, the box door 4 is closed so that the plug block 8 is inserted into the socket 7, and the plug block 8 pushes the limit block 57 to move toward the inside of the box body 1 and squeezes the first spring 56. When the limit hole 10 corresponds to the limit hole 10, the limit block 57 is reset under the elastic force of the first spring 56, realizing the limit of the plug block 8, that is, completing the limit of the box door 4 and the box body 1. When it is necessary to open the box door 4, the shaft 52 is rotated, and the shaft 52 drives the drive disk to rotate, and the drive disk drives the drive rod 54 to move through the connecting rod 53. The driving rod 54 drives the limit block 57 to move toward the principle limit hole 10, so that the limit block 57 does not limit the limit hole 10, completing the opening of the box door 4. At the same time, since the movement of the driving rod 54 will drive the first movable plate 55 to squeeze the first spring 56, when the rotating shaft 52 is released, the limit block 57 is reset under the elastic force of the first spring 56, so as to facilitate the next limitation of the limit hole 10. The overall operation is simple, and the automatic limitation of the box door 4 is realized.

Secondly, the applicable method of the tester body 6 can refer to the patent document with patent announcement number CN220983482U.

[0029] In the embodiment of the present utility model, Figure 5 As shown, the driving rod 54 is an L-shaped structure.

A fixed plate 12 is fixedly connected to the slider 14 on the box body 1, and an elastic telescopic rod 13 is fixedly connected between the fixed plate 12 and the slider 14. The elastic telescopic rod 13 includes a fixed column 135, which is fixed on the fixed plate 12, and a second movable plate 132 is movably provided in the fixed column 135. A second movable groove 134 for the second movable plate 132 to move is provided in the fixed column 135. The second movable groove 134 is provided with a second spring 133 fixedly connected to the second movable plate 132, and the movable rod 131 has two ends respectively connected to the second movable plate 132. When the door 4 is closed, the slider 132 is moved in the opposite direction under the elastic force of the second spring 133, thereby driving the baffle 16 to limit the heat dissipation hole 3 again, thereby realizing the automatic opening and closing of the heat dissipation hole 3 as a whole, saving the time of manual operation and improving the overall work efficiency; it should be noted that the baffle 16 and the slider 14 can be made of lightweight material to ensure that the second spring 133 can drive them to move.

When the limit hole 10 corresponds to the limit hole 10, the limit block 57 is reset under the elastic force of the first spring 56, thereby limiting the plug block 8, that is, completing the limitation of the box door 4 and the box body 1. When it is necessary to open the box door 4, the rotating shaft 52 is rotated, and the rotating shaft 52 drives the driving disk to rotate.

At the same time, when the box door 4 is opened, the rotation of the box door 4 will drive the traction rope 11 to move, and the traction rope 11 drives the slider 14 to slide along the slide groove 15, and the slider 14 drives the baffle 16 to move along the moving groove 9, so that the baffle 16 no longer blocks the heat dissipation hole 3. At the same time, the movement of the slider 14 will drive the movable rod 131 to move toward the inside of the fixed column 135, so that the second movable plate 132 squeezes the second spring 133. The overall operation is simple, and the automatic limitation of the box door 4 is realized. The limiting structure has high stability, which prevents the box door 4 from falling off, thereby improving the protection of the tester body.
