[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0020] Reference Figure 1-4 As shown, a mounting assembly of a power transformer includes two fixing rods 1, and mounting assemblies 2 are arranged on the left and right sides of the two fixing rods 1. The mounting assembly 2 includes a mounting block 201, and the mounting block 201 is fixedly connected to the end of the fixing rod 1. A mounting groove 202 is provided inside the mounting block 201, and the shape of the mounting groove 202 is L-shaped. A sliding hole 203 is penetrated through the upper surface of the mounting block 201, and a clamping rod 204 is slidably connected inside the sliding hole 203. A fixing block 205 is fixedly connected to the bottom of the clamping rod 204 and the inside of the mounting groove 202. A connecting rod 206 is rotatably connected to the end of the fixing block 205 away from the clamping rod 204, and a clamping block 207 is rotatably connected to the upper end of the mounting groove 202. The upper end of the connecting rod 206 is rotatably connected to the clamping block 207 near the clamping rod 204.

[0021] Specifically, a compression spring 209 is sleeved on the surface of the clamping rod 204 , the upper end of the compression spring 209 is fixedly connected to the top wall of the mounting groove 202 , and the bottom of the compression spring 209 is fixedly connected to the upper surface of the fixing block 205 , and the compression spring 209 serves as a reset power source for the mounting assembly 2 .

[0022] Preferably, a plurality of friction pads 208 are fixedly connected to the bottom of the clamping block 207. The friction pads 208 are made of wood, leather, rubber and aluminum alloy. The friction pads 208 can effectively increase the contact area and friction coefficient between the clamping block 207 and the I-beam 5, so that they are fixed together more firmly.

[0023] Specifically, the transformer body 4 is disposed at the upper ends of the two fixing rods 1 , and I-beams 5 are fixedly connected to the left and right sides of the bottom of the transformer body 4 .

[0024] Specifically, a fixing component 6 is provided on the inner side of the installation component 2, and the fixing component 6 includes a fixing plate 601, which is fixedly connected to the inner upper end of the installation block 201, and a reinforcing plate 602 is fixedly connected to the bottom of the fixing plate 601, and the reinforcing plate 602 is also fixedly connected to the installation block 201. The reinforcing plate 602 and the fixing plate 601 are relatively vertically arranged to improve the bearing capacity of the fixing plate 601.

[0025] Specifically, a plurality of fixing bolts 603 are threadedly connected to the bottom of the fixing plate 601. The fixing bolts 603 are used to connect the fixing plate 601 and the I-beam 5. The fixing bolts 603 at this location only play a role of limiting to prevent the I-beam 5 from sliding.

[0026] Optionally, limit strips 3 are further provided at the left and right ends of the fixing rod 1 and the outside of the mounting assembly 2, and the two ends of the limit strip 3 are respectively fixedly connected to the mounting blocks 201 at both ends. The limit strip 3 is U-shaped, and its length can be customized, and is used to fix the fixing rod 1 and the mounting assembly 2 to improve the stability of the entire mounting structure.

[0027] Working principle: During installation, first weld the I-beam 5 to the bottom of the transformer body 4. The I-beam 5 presses the clamping rod 204 downward to drive the fixed block 205 to move synchronously. The fixed block 205 pulls the clamping block 207 downward to make the clamping block 207 rotate around the rotating shaft on its left side. The right side of the clamping block 207 clamps the I-beam 5. Then, the I-beam 5 is limited by the fixing bolts 603 on the fixing plate 601. When disassembly is required, loosen the fixing bolts 603, lift the transformer body 4 upward, and the compression spring 209 contracts to drive the fixed block 205 to move upward. The connecting rod 206 makes the clamping block 207 rotate to the left, thereby loosening the fixation of the I-beam 5.
