[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.
[0016] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0017] Please see the appendix Figure 1 - Appendix Figure 7 The present invention provides an adjustable base for calibrating an insulation resistance meter, comprising an upper mounting plate 14 disposed within a base body 1, a side pull rod 9 and a main pull rod 11 slidably connected to the base body 1, an adjustment mechanism 2 installed within the base body 1, and a lower mounting plate 13 installed at the upper end of the adjustment mechanism 2. The adjustment mechanism 2 includes a lower mounting base 3, an upper mounting base 6, a limiting rod 4, and a spring 5. One end of the spring 5 is connected to the limiting rod 4, and the other end of the spring 5 is connected to the lower mounting base 3. A limiting plate 12 is fixedly connected inside the lower mounting base 3. The lower mounting base 3 is rotatably connected to the upper mounting base 6. A rotating plate 7 is connected to the upper mounting base 6. Three limiting holes 8 are evenly opened on the rotating plate 7. In actual use, the operator can pull the side pull rod 9 to slide the limiting rod 4, so that the limiting rod 4 is disengaged from the limiting hole 8, and then the upper mounting plate 14 can be rotated. By pulling the main pull rod 11, the limiting rod 4 is slid, the spring 5 is extended, and one end of the limiting rod 4 is disengaged from the limiting hole 8 opened on the rotating plate 7, so the upper mounting plate 14 can be rotated to achieve forward tilting, backward tilting, left tilting, and right tilting.
[0018] In Example 1, the rotating plate 7 has a fan-shaped annular plate structure, as shown in the example. Figure 6 As shown, when one end of the limiting rod 4 is engaged in the limiting hole 8 at the middle position on the rotating plate 7, and both the upper and lower adjusting mechanisms 2 of the lower mounting plate 13 are in this state, the upper mounting plate 14 is parallel to the plane where the device is placed. For example... Figure 1 The direction where the main tie rod 11 is located is the front; A thrust spring 10 is fixedly installed on the side pull rod 9, and the other end of the thrust spring 10 is fixedly installed on the inner wall of the base body 1, as shown in the example. Figure 4 As shown, the side pull rod 9 is in its initial state, and it does not obstruct the swing of the limit rod 4. At this time, the thrust spring 10 is in a relaxed state, neither extended nor compressed. When the upper mounting plate 14 is parallel to the plane where the device is placed, a person can pull the side pull rod 9 to compress the thrust spring 10, thus bringing the side pull rod 9 into the initial state. Figure 6 At the indicated position, the limiting rod 4 can be slid by pulling the side pull rod 9, causing the elastic spring 5 to extend and disengage one end of the limiting rod 4 from the limiting hole 8 on the rotating plate 7. Personnel can then rotate the upper mounting plate 14, causing the lower mounting seat 3 on the upper mounting base 6 to rotate, allowing the insulation resistance meter to tilt to the left or right. The rotation angle of the rotating plate 7 is limited by the limiting plate 12. Releasing the side pull rod 9 causes the thrust spring 10 to extend, returning the side pull rod 9 to its original position. When the limiting rod 4 aligns with the limiting hole 8 on the rotating plate 7, the elastic spring 5 pulls one end of the limiting rod 4 into the limiting hole 8, thus limiting the rotating plate 7 and fixing the upper mounting base 6, preventing the upper mounting plate 14 from moving. Personnel must then rotate the upper mounting plate 14 according to the above operation, causing one end of the limiting rod 4 to engage with the limiting hole 8 in the middle position on the rotating plate 7, restoring the upper mounting plate 14 to a state parallel to the plane where the device is placed. One end of the limiting rod 4 is stuck on the limiting hole 8, which is a circular hole structure. The limiting rod 4 is a combination of a "T" shaped column and a hemisphere. A lower mounting base 3 is fixedly installed inside the base body 1. The lower mounting base 3 is slidably connected to the limiting rod 4, and the limiting rod 4 is fixedly connected to the main pull rod 11. By pulling the main pull rod 11, the operator can slide the limiting rod 4, causing the spring spring 5 to extend and disengage one end of the limiting rod 4 from the limiting hole 8 on the rotating plate 7. The operator can then rotate the upper mounting plate 14, causing the lower mounting plate 13 to rotate accordingly, thus enabling the insulation resistance meter to tilt forward and backward. When the main pull rod 11 is released and the limiting rod 4 is aligned with the limiting hole 8 on the rotating plate 7, the spring spring... Spring 5 can pull one end of the limiting rod 4 into the limiting hole 8, thereby limiting the rotating plate 7 and fixing the upper mounting base 6, making the upper mounting plate 14 unable to move, so that testing can be carried out. Afterwards, the personnel need to rotate the upper mounting plate 14 according to the above operation, so that one end of the limiting rod 4 is inserted into the limiting hole 8 in the middle position on the rotating plate 7, so that the upper mounting plate 14 returns to the state of being parallel to the plane where the device is placed. Through the above settings, it is convenient for personnel to make adjustments and operations, facilitates personnel to carry out experimental work, and makes the device more reliable and simple to operate.
[0019] In the second embodiment, the bottom of the upper mounting plate 14 is connected to the adjustment mechanism 2. A connecting block 15 and a fixing plate 18 are fixedly connected to the upper surface of the upper mounting plate 14. The fixing plate 18 has a square plate structure and is fixedly connected to the second rubber pad 19. Personnel can place the insulation resistance meter on the upper mounting plate 14 so that the side of the upper mounting plate 14 contacts the second rubber pad 19 fixedly connected to the side of the fixing plate 18. The second rubber pad 19 can deform to adapt to the unevenness of the side of the insulation resistance meter. The connecting block 15 has an "L"-shaped plate structure. The connecting block 15 is threadedly connected to the threaded section on the rotating mechanism 16. A first rubber pad 17 is fixedly connected to the rotating mechanism 16. Personnel can rotate the rotating mechanism 16 so that the threaded section on the rotating mechanism 16 rotates along the threaded hole on the connecting block 15, so that the first rubber pad 17 fixedly connected to the rotating mechanism 16 is close to the insulation resistance meter. The first rubber pad 17 contacts the side of the insulation resistance meter and squeezes the insulation resistance meter. With the above, the insulation resistance meter can be fixed on the upper mounting plate 14, making the installation more stable and convenient for personnel to use.
[0020] Working principle: First, by pulling the side pull rod 9, the operator can slide the limiting rod 4, causing it to disengage from the limiting hole 8. Then, the operator can rotate the upper mounting plate 14. By pulling the main pull rod 11, the operator can slide the limiting rod 4, causing one end of the limiting rod 4 to disengage from the limiting hole 8 on the rotating plate 7. This allows the operator to rotate the upper mounting plate 14, enabling forward, backward, left, and right tilting. This facilitates subsequent calibration work, allows for easy adjustment, and makes the device more reliable. It eliminates the need for repeated installation and disassembly, and its simple operation makes it easy for operators to use.
