[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil. Because dry-type transformers have the advantages of strong short-circuit resistance, low maintenance workload, high operating efficiency, small size and low noise, they are often used in places with high requirements for fire protection and explosion protection.

After the block completely passes through the fixing hole, the spring rebounds, pushing the block outward and clamping the top surface of the channel steel base, thereby fastening the dry-type transformer body. The fastening efficiency is high and it is very convenient to use.

[0004] However, although the above patent can quickly fasten the dry-type transformer, the disassembly operation of the dry-type transformer after fixation is relatively troublesome, which is not conducive to timely repair and replacement when the dry-type transformer fails.

[0023] See also Figure 1-4 A fastening device for a dry-type transformer in this embodiment includes a base 1 and a rotating rod 7, a fastening installation mechanism is arranged on the top of the base 1, and an auxiliary component is arranged on the outer side of the rotating rod 7.

[0024] Embodiment 1: The fastening installation mechanism includes a transformer body 2 movably connected to the top of the base 1, two limit vertical plates 3 are fixedly connected to the bottom of the transformer body 2, and the bottom of the limit vertical plates 3 is fixedly connected to the limit horizontal plate 4. A sliding groove 101 is opened on the top of the base 1, and the sliding groove 101 is a convex shape, which facilitates the limit vertical plate 3 and the limit horizontal plate 4 to slide inside the base 1 using the sliding groove 101.

[0025] The base 1 is internally fixedly connected with a buffer pad 5 located on the inner wall of the sliding groove 101 , so as to conveniently utilize the provided buffer pad 5 to enhance the activity stability of the limiting vertical plate 3 and the limiting horizontal plate 4 , and provide a certain degree of buffer protection for the transformer body 2 .

[0026] In this embodiment, the top of the limiting horizontal plate 4 is fixedly connected to a fixed plate 6, the interior of the fixed plate 6 is rotatably connected to a rotating rod 7, two limiting rings 9 are arranged on the outer side of the rotating rod 7, and a movable groove 401 corresponding to the position of the limiting ring 9 is opened inside the limiting horizontal plate 4, and a limiting groove 102 located below the sliding groove 101 and corresponding to the position of the limiting ring 9 is opened inside the base 1, so that the limiting ring 9 can use the movable groove 401 to enter the limiting groove 102, thereby limiting the forward and backward movement of the limiting horizontal plate 4.

[0027] Among them, the limiting ring 9 is composed of an arc segment and a straight line segment, which makes it convenient to stagger the limiting ring 9 and the limiting groove 102 when the straight line segment of the limiting ring 9 is facing downward, thereby facilitating the movement of the limiting cross plate 4. The limiting ring 9 and the rotating rod 7 are fixedly connected to the opposite side with a connecting block 8, which facilitates the use of the connecting block 8 to maintain the stable installation of the limiting ring 9.

[0028] In this embodiment, a plurality of limit sliders 10 are fixedly connected to the outer side of the arc segment of the limit ring 9, and a guide block 11 corresponding to the position of the limit ring 9 is fixedly connected to the top of the limit cross plate 4. A first limit slide groove slidably adapted to the limit slider 10 is provided on the side of the guide block 11 close to the limit ring 9, and a second limit slide groove located on the outside of the movable groove 401 is provided inside the limit cross plate 4.

[0029] Among them, a third limiting slide groove located outside the limiting groove 102 is opened inside the base 1, and the second limiting slide groove and the third limiting slide groove are both slidably adapted to the limiting slider 10, so that the limiting slider 10 can move in the first limiting slide groove, the second limiting slide groove and the third limiting slide groove, thereby improving the rotation stability of the limiting ring 9.

[0030] Embodiment 2: The auxiliary component includes a mounting block 12 fixedly connected to one side of the rotating rod 7, a pull rod 13 is slidably connected inside the mounting block 12, an end of the pull rod 13 close to the fixed plate 6 is fixedly connected to a positioning block 14 slidably connected to the mounting block 12, and an extrusion spring 15 fixedly connected to the positioning block 14 and the mounting block 12 is fixedly connected to the outer side of the pull rod 13, so that the positioning block 14 can move toward the fixed plate 6 under the action of the extrusion spring 15.

[0031] Among them, the positioning block 14 is T-shaped, and a positioning groove is opened on the side of the fixed plate 6 close to the mounting block 12, so that when the positioning block 14 extends to the outside of the mounting block 12, the positioning block 14 can use the positioning groove to extend to the inside of the fixed plate 6, thereby limiting the rotation of the rotating rod 7.

[0032] The beneficial effects of the above embodiments are:

[0033] The fastening device of the dry-type transformer can push the transformer body 2 to make the limit vertical plate 3 and the limit horizontal plate 4 move in the sliding groove 101, thereby limiting the up and down movement and left and right movement of the transformer body 2, and rotating the rotating rod 7 can also make the limit ring 9 embed into the limit groove 102, so as to facilitate the front and back movement of the limit horizontal plate 4, thereby making it impossible for the transformer body 2 to move left and right, front and back, and up and down, thereby achieving the installation and fastening of the transformer body 2 and effectively improving the fastening efficiency; in addition, when the transformer body 2 fails, the limit ring 9 can be separated from the base 1 by rotating the rotating rod 7, so that the transformer body 2 is easy to disassemble, so as to facilitate its maintenance and replacement in time, and further improve the practical effect of the device.

[0034] The working principle of the above embodiment is:

[0035] When the fastening device of the dry-type transformer is used, the limiting vertical plate 3 and the limiting horizontal plate 4 need to be pushed into the sliding groove 101 inside the base 1, so as to limit the vertical and horizontal movement of the transformer body 2. When the limiting vertical plate 3 and the limiting horizontal plate 4 contact the rear end surface of the sliding groove 101, the rotating rod 7 can be rotated to rotate the limiting ring 9, so that the limiting ring 9 passes through the movable groove 401 and enters the limiting groove 102, so as to facilitate the forward and backward movement of the limiting horizontal plate 4, thereby realizing the installation and fastening of the transformer body 2 and effectively improving the fastening efficiency.

[0036] At this time, the positioning plug 14 can be extended to the positioning groove inside the fixing plate 6 under the action of the extrusion spring 15, so as to conveniently limit the rotation of the rotating rod 7, so as to prevent the limit ring 9 from rotating and keep the installation of the transformer body 2 stable;

[0037] When the transformer body 2 needs to be disassembled for inspection, replacement and maintenance, the pull rod 13 can be pulled to disengage the positioning block 14 from the fixed plate 6, thereby rotating the rotating rod 7 to drive the limit ring 9 to rotate, so that the limit ring 9 disengages from the limit groove 102, thereby facilitating the extraction of the transformer body 2 and realizing the disassembly of the transformer body 2.
