[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 A mobile dry-type transformer in this embodiment includes a base 1 and a dry-type transformer body 2. A movable limit component is installed on the base 1, and a fixed position component is installed on the base 1.

[0025] Embodiment 1: The movable limiting assembly comprises a self-braking wheel 3 fixedly mounted on the bottom of the base 1 . The number of the self-braking wheels 3 is four and they are symmetrically installed. A rotating clamping plate 4 is rotatably installed on the outer side of the base 1 .

[0026] Two extrusion springs 5 ​​are fixedly installed on opposite sides of the two rotating clamps 4 . A first installation groove is opened on opposite sides of the two rotating clamps 4 . The extrusion springs 5 ​​are fixedly connected to the rotating clamps 4 through the first installation groove.

[0027] A clamp 6 is fixedly installed on the opposite side of the two groups of extrusion springs 5, and a limit plate 7 is fixedly installed on the top of the base 1. There are two limit plates 7. Four bearings 8 are fixedly installed on the top of the base 1. A second mounting groove is opened on the top of the base 1. The bearing 8 is fixedly connected to the base 1 through the second mounting groove. A rotating rod 9 is rotatably installed inside the two groups of bearings 8.

[0028] It should be noted that the mobile dry-type transformer is equipped with a movable limiting component, which makes it convenient for the user to push the dry-type transformer body 2 for moving and transporting when the dry-type transformer body 2 needs to be transported, thereby improving the efficiency of transporting the dry-type transformer body 2. During transportation, the dry-type transformer body 2 is limited to reduce the possibility of the dry-type transformer body 2 falling and being damaged during transportation.

[0029] Specifically, when the mobile dry-type transformer is in use, the dry-type transformer body 2 is placed on the base 1, and the two limit plates 7 limit the two sides of the dry-type transformer body 2, and then the two rotating clamps 4 are rotated to be perpendicular to the base 1, and then the extrusion spring 5 is compressed, so that the two clamps 6 limit and clamp the other two ends of the dry-type transformer body 2, and the dry-type transformer body 2 is limited, so as to reduce the possibility of the dry-type transformer body 2 falling and being damaged during transportation, and the device is pushed to slide by the self-braking wheel 3 to meet the use requirements.

[0030] Example 2: Please refer to Figure 1 On the basis of the first embodiment, a fixed position component is further installed on the base 1, and the fixed position component includes a mounting frame 10 fixedly installed on the side opposite to the rotating rod 9, and telescopic springs 11 are fixedly installed inside the two sets of mounting frames 10.

[0031] Among them, a slide plate 12 is fixedly installed on the opposite side of the two sets of telescopic springs 11, and a slide groove is opened inside the installation frame 10. The slide plate 12 is slidably connected to the installation frame 10 through the slide groove, which is convenient for providing guidance for the sliding of the slide plate 12, making the movement of the slide plate 12 more convenient.

[0032] A moving hole is opened at the top of the installation frame 10, and the slide plate 12 extends to the outside of the installation frame 10 through the moving hole, so that the user can move the slide plate 12 by pushing the push block 14. The limiting blocks 13 are fixedly installed on the opposite sides of the two groups of slide plates 12.

[0033] In addition, extension holes are provided on the opposite sides of the two sets of mounting frames 10, and snap-in grooves are provided on both sides of the rotating clamping plate 4. The limit blocks 13 are snap-connected with the rotating clamping plate 4 through the extension holes and the snap-in grooves, so as to facilitate the limited fixing of the adjusted rotating clamping plate 4. Push blocks 14 are fixedly installed on the tops of the two sets of slides 12.

[0034] It should be noted that the mobile dry-type transformer is installed with a fixed position assembly, which facilitates the limiting and fixing of the rotating clamping plate 4, further improves the limiting of the dry-type transformer body 2, and improves the quality of the transportation of the dry-type transformer body 2.

[0035] Specifically, the mobile dry-type transformer pushes the two push blocks 14 in opposite directions, driving the telescopic spring 11 to be compressed, thereby causing the two slide plates 12 to move in opposite directions in the installation frame 10, driving the limit blocks 13 to be stored inside the installation frame 10, so as to facilitate the rotation of the clamping plate 4. After the rotating clamping plate 4 is adjusted and rotated, the two push blocks 14 are released, so that the telescopic spring 11 is reset, and then the limit blocks 13 are pushed out of the installation frame 10, and are clamped with the rotating clamping plate 4, and the rotating clamping plate 4 is limited and fixed, so as to facilitate the limit clamping of the dry-type transformer body 2.

[0036] The working principle of the above embodiment is:

[0037] (1) When the mobile dry-type transformer is used, the dry-type transformer body 2 is placed on the base 1, and the two limit plates 7 limit the two sides of the dry-type transformer body 2. Then, the two rotating clamps 4 are rotated to be perpendicular to the base 1, and then the extrusion spring 5 is compressed, so that the two clamps 6 limit and clamp the other two ends of the dry-type transformer body 2, and the dry-type transformer body 2 is limited to reduce the possibility of the dry-type transformer body 2 falling and being damaged during transportation. The self-braking wheel 3 pushes the device to slide, thereby meeting the use requirements.

[0038] (2) The mobile dry-type transformer pushes the two push blocks 14 in opposite directions, driving the telescopic spring 11 to be compressed, thereby causing the two slide plates 12 to move in opposite directions within the installation frame 10, driving the limit blocks 13 to be stored inside the installation frame 10, so as to facilitate the rotation of the clamping plate 4. After the rotating clamping plate 4 is adjusted and rotated, the two push blocks 14 are released, so that the telescopic spring 11 is reset, and then the limit blocks 13 are pushed out of the installation frame 10, and are engaged with the rotating clamping plate 4, so that the rotating clamping plate 4 is limited and fixed, so as to facilitate the limit clamping of the dry-type transformer body 2.
