[0036] Working principle: In this embodiment, the present invention also proposes a method for using a pressure-resistant and shock-resistant dry-type transformer, comprising the following steps:

[0037] Step 1: first install the device at the designated position through the positioning seat 13, then install the transformer group 1 in the device, and then turn the knob 33 to control the adjustment screw 32 to rotate, and the adjustment screw 32 is threadedly connected to the mounting plate 31, and then the adjustment screw 32 is rotatably connected to the connection box 34, and the connection box 34 is placed in the movable cavity. When the adjustment screw 32 rotates, the connection box 34 is controlled to move in the movable cavity. When the connection box 34 moves in the movable cavity, the wedge block 35 is controlled to move. When the wedge block 35 leaves the limit groove on the telescopic shaft 28, the telescopic shaft 28 can move in the telescopic sleeve 27;

[0038] Step 2: When the telescopic shaft 28 can move, the hexagonal groove 25 is used to control the rotation of the rotary block. When the rotary block rotates, the bidirectional screw rod 24 is controlled to rotate. The bidirectional screw rod 24 is threadedly connected with the moving seats 26 at both ends, thereby controlling the relative movement of the moving seats 26 at both ends. At this time, the telescopic shaft 28 and the telescopic sleeve 27 at the upper and lower ends form a triangle with the support plate 23. The position of the moving seat 26 is changed as needed to adjust the angle of the triangle, thereby adjusting the compressive strength; when the angle is adjusted, the control knob 33 is rotated in the opposite direction. Similarly, the control wedge block 35 is controlled to enter the limit groove provided on the telescopic shaft 28, thereby locking the telescopic shaft 28;

[0039] Step 3, after the angle is locked, turn the adjusting nuts 9 on both sides of the lower beam 6, and adjust the distance between the lower beam 6 and the supporting plate 12 by threading the adjusting nuts 9 with the guide rods 8 on both sides, thereby adjusting the buffer height of the lower beam 6 by the first spring 11; when the buffer height is adjusted, connect the conductive rod 4 to the transformer group 1, and then connect the traction line 5 to the transformer group 1;

[0040] Step 4, when the transformer group 1 shakes up and down, the lower crossbeam 6 will also shake up and down. At this time, the guide rod 8 will move up and down in the guide port, and the first damping strip 7 installed through the guide port will abut against the guide rod 8, and then the first springs 11 at both ends will buffer its up and down shaking, thereby achieving the effect of up and down anti-vibration and preventing the transformer group 1 from being damaged; when the transformer group 1 shakes back and forth, the sliding seats 18 at both ends of its connecting rod 17 move back and forth. When the sliding seat 18 moves back and forth, the second damping strip 19 installed inside the sliding seat 18 is controlled to move back and forth. The second damping strip 19 abuts against the connecting rod 17, and then the second spring 20 is compressed or stretched when the sliding seats 18 at both ends move, thereby achieving the effect of front and back anti-vibration; when the sliding seat 18 moves back and forth, the connecting rod 21 is controlled to rotate on the mounting seat 16. At this time, the connecting plate 14 movably hinged to the positioning seat 13 and the mounting seat 16 will move with the shaking of the supporting plate 12, thereby performing front and back anti-vibration buffering on the transformer group 1.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
