[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] Example

[0031] like Figure 1-4As shown, it includes a voltage transformer body 1, a positioning mechanism 2 is provided at the bottom of the voltage transformer body 1, the positioning mechanism 2 includes a positioning seat 201 installed at the bottom of the middle part of the voltage transformer body 1, and a horizontal adjustment mechanism 3 is provided below the positioning seat 201. The horizontal adjustment mechanism 3 includes an adjustment seat 301 installed below the positioning seat 201, and a mounting seat 302 is installed on one side of the top of the adjustment seat 301. The two ends of the mounting seat 302 are respectively provided with a first connecting arm 303, and a movable block 304 is provided on the top of the mounting seat 302, and the movable block 304 is provided between the first connecting arms 303. The inner wall of the mounting seat 302 is penetrated by a second adjusting rod 305, and the second adjusting rod 305 is penetrated by the movable block 304 and is threadedly connected to the movable block 304. The horizontal adjustment mechanism 3 also includes a plurality of adjusting members in the adjustment position. A mounting plate 306 is installed on the top of the seat 301, and the mounting plate 306 is arranged on the side of the mounting seat 302 close to the midpoint of the adjustment seat 301. A second connecting arm 307 is provided between the first connecting arm 303 and the mounting plate 306, and the two ends of the second connecting arm 307 are rotatably connected to the midpoint of the first connecting arm 303 and the mounting plate 306 respectively. A first circular shaft 308 is passed through the middle and lower part of the first connecting arm 303, and a second circular shaft 309 is passed through the middle and upper part of the first connecting arm 303. The horizontal adjustment mechanism 3 also includes a slide groove 310 opened at both ends of the mounting seat 302, a second positioning bolt 311 is threadedly connected to one side of the mounting seat 302, and circular holes 312 are opened at both ends of the bottom of the movable block 304, and a second adjusting button 313 is fixedly connected to the side of the second adjusting rod 305 away from the midpoint of the adjustment seat 301.

[0032] It should be noted that, in this embodiment, when the adjustment seat 301 is installed on a plane or an inclined surface and the horizontal position of the voltage transformer body 1 needs to be adjusted, the second adjustment button 313 is rotated to drive the second adjustment rod 305 to rotate, and the movable block 304 moves toward the midpoint of the adjustment seat 301 or away from the midpoint due to the threaded transmission at the top of the mounting seat 302. If the movable block 304 moves toward the midpoint: the lower end of the first connecting arm 303 is pulled inward by the first circular shaft 308, and the upper end of the first connecting arm 303 is supported by the second circular shaft 309, driving the corresponding side of the positioning seat 201 to rise; if the movable block 304 is away from the midpoint: the movable block 304 pushes the lower end of the first connecting arm 303 to swing outward, and the positioning seat 20 1, the corresponding side descends, the first connecting arm 303 is rotatably connected to the mounting plate 306 through the second connecting arm 307, forming a four-bar linkage, which converts the horizontal movement of the movable block 304 into a height change of the positioning seat 201. The horizontal adjustment mechanism 3 cooperates symmetrically on both sides to offset the inclination of the plane or inclined surface. The horizontal state of the voltage transformer body 1 is monitored by a level or other measuring tool, and the second adjustment knobs 313 on both sides are adjusted synchronously until the voltage transformer body 1 is in a horizontal position. After the adjustment is completed, the second positioning bolts 311 are aligned and inserted into the holes on the side walls of the mounting seat 302, and the second positioning bolts 311 are tightened to fix the position of the movable block 304 in the mounting seat 302 to prevent loosening;

[0033] Among them, the slide groove 310 is opened at both ends of the mounting seat 302, providing a sliding track for the first circular shaft 308 and limiting its moving direction. The circular hole 312 is located at both ends of the bottom of the movable block 304, mainly used to cooperate with the first circular shaft 308. The aperture of the circular hole 312 is adapted to the diameter of the first circular shaft 308, so that the first circular shaft 308 can pass through the circular hole 312 to connect the movable block 304 with the first connecting arm 303. At the same time, through the cooperation between the first circular shaft 308 and the slide groove 310 (the first circular shaft 308 is passed through the slide groove 310 and can slide in the groove), the linear motion of the movable block 304 is converted into the angle change of the first connecting arm 303, thereby realizing the linkage of the horizontal adjustment mechanism 3.

[0034] like Figure 5-7 As shown, the positioning mechanism 2 includes a positioning seat 201 installed at the lower middle part of the voltage transformer body 1, the positioning mechanism 2 also includes a center block 202 installed at the center position of the bottom wall of the positioning seat 201, the inner wall of the positioning seat 201 is penetrated by a first adjusting rod 203, the inner wall of the positioning seat 201 is provided with two groups of positioning blocks 204, and the positioning blocks 204 are symmetrically installed on both sides of the center block 202 with the midpoint of the center block 202 as the symmetry axis, one side of the first adjusting rod 203 is fixedly connected to the first adjusting button 205, the positioning mechanism 2 also includes a first adjusting rod 203 fixed to the center block 202, and the first adjusting rod 203 is fixed to the center block 202. The limiting grooves 206 are opened on the two end walls of the seat 201, and the first adjusting rod 203 is provided with two groups of blocks 207 near the middle position, and the block 207 is arranged between the center block 202 and the positioning block 204. The two ends of the positioning block 204 are fixedly connected to the limiting plates 208, and the limiting plates 208 are slidably connected to the limiting grooves 206. The first positioning bolt 209 is embedded in the hole of the first adjusting button 205. The voltage transformer body 1 includes positioning grooves 101 opened on both sides of the lower side, and the positioning block 204 is embedded in the positioning groove 101.

[0035] It should be noted that, in this embodiment, when installing the voltage transformer, the initial position of the positioning block 204 is on the inner wall of the positioning seat 201 close to the side wall of the positioning seat 201, and then the bottom of the voltage transformer body 1 is installed in the positioning seat 201. After the voltage transformer body 1 is placed, the first adjusting button 205 is turned, and the first adjusting button 205 drives the first adjusting rod 203 to rotate. Since the surfaces on both sides of the first adjusting rod 203 are threaded structures and are threadedly connected with the two sets of positioning blocks 204, as the first adjusting rod 203 is rotated, the first adjusting rod 203 is rotated. Rotate, the two side blocking blocks 204 move toward the center due to the thread transmission, slide in the limiting groove 206 through the limiting plate 208, ensure linear movement and clamp the voltage transformer body 1, until the two sets of blocking blocks 204 are completely embedded in the positioning grooves 101 on both sides of the voltage transformer body 1, then align and insert the first positioning bolt 209 into the hole on the side wall of the positioning seat 201, and tighten the first positioning bolt 209, and fix the first adjusting button 205 to the side wall of the positioning seat 201 through threaded connection to prevent the blocking blocks 204 from loosening;

[0036] Among them, the center block 202 is located at the center of the bottom wall of the positioning seat 201, serving as the installation reference of the first adjustment rod 203 and the symmetry center of the positioning block 204. There are two groups of blocks 207, which are mounted near the middle of the first adjustment rod 203 and located between the center block 202 and the positioning block 204. They are used to limit the movement range of the positioning block 204 to prevent structural damage due to excessive adjustment.

[0037] Working principle of the present invention:

[0038] Refer to the instruction manual Figure 1-7 When the adjustment seat 301 is installed on a plane or an inclined surface and the horizontal position of the voltage transformer body 1 needs to be adjusted, the second adjustment knob 313 is first rotated to drive the second adjustment rod 305 to rotate, and the movable block 304 moves toward the midpoint of the adjustment seat 301 or away from the midpoint at the top of the mounting seat 302 due to the thread transmission;

[0039] If the movable block 304 moves toward the midpoint: the lower end of the first connecting arm 303 is pulled inward by the first circular shaft 308, and the upper end of the first connecting arm 303 is supported by the second circular shaft 309, driving the corresponding side of the positioning seat 201 to rise;

[0040] If the movable block 304 is away from the midpoint: the movable block 304 pushes the lower end of the first connecting arm 303 to swing outward, and the corresponding side of the positioning seat 201 drops. The first connecting arm 303 is rotatably connected to the mounting plate 306 through the second connecting arm 307, forming a four-bar linkage, which converts the horizontal movement of the movable block 304 into a height change of the positioning seat 201. The two sides of the horizontal adjustment mechanism 3 cooperate symmetrically to offset the inclination of the plane or inclined surface. The horizontal state of the voltage transformer body 1 is monitored by a level or other measuring tool, and the second adjustment knobs 313 on both sides are adjusted synchronously until the voltage transformer body 1 is in a horizontal position;

[0041] After the adjustment is completed, align the second positioning bolt 311 and insert it into the hole on the side wall of the mounting seat 302, and tighten the second positioning bolt 311 to fix the position of the movable block 304 in the mounting seat 302 to prevent it from loosening;

[0042] Then, the voltage transformer body 1 is installed, and the initial position of the positioning block 204 is on the inner wall of the positioning seat 201 close to the side wall of the positioning seat 201, and then the bottom of the voltage transformer body 1 is installed in the positioning seat 201;

[0043] After the voltage transformer body 1 is placed, the first adjusting button 205 is turned, and the first adjusting button 205 drives the first adjusting rod 203 to rotate. Since the surfaces on both sides of the first adjusting rod 203 are threaded structures and are threadedly connected to the two groups of blocking blocks 204, as the first adjusting rod 203 rotates, the blocking blocks 204 on both sides move toward the center due to thread transmission, and slide in the limiting groove 206 through the limiting plate 208, ensuring linear movement and clamping the voltage transformer body 1 until the two groups of blocking blocks 204 are completely embedded in the positioning grooves 101 on both sides of the voltage transformer body 1, and then align the first positioning bolt 209 and insert it into the hole on the side wall of the positioning seat 201, and tighten the first positioning bolt 209, and fix the first adjusting button 205 to the side wall of the positioning seat 201 through threaded connection to prevent the blocking blocks 204 from loosening.
