[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-3, a safety protection type transformer skeleton, including a connecting pipe 1 and a connecting pipe 2, both ends of which are fixedly connected with a side plate 3, a through hole is opened through the outer wall of the side plate 3, and is communicated with the inside of the connecting pipe 1 and the connecting pipe 2, two groups of adjacent side plate 3 outer walls are in contact with each other, one group of side plates 3 outer walls are threadedly connected with multiple groups of screws 6, and the outer wall of the side plate 3 adjacent to it is provided with multiple groups of fixing holes 10, the positions of the multiple groups of fixing holes 10 correspond to the positions of the multiple groups of screws 6, and the multiple groups of fixing holes 10 are respectively threadedly connected to the corresponding fixing holes 10, and one group of side plates 3 outer walls are installed with a limiting device for limiting the position of the screws 6;

[0020] In this structure, the basic framework of the transformer skeleton is formed by the arrangement of the connecting pipe 1 and the connecting pipe 2, and the side plate 3 is connected to the inside of the connecting pipe through the through hole, so that the overall structure has a good airflow channel to ensure the heat dissipation effect of the transformer during operation. Since a plurality of fixing holes 10 and corresponding screws 6 are arranged on the side plate 3, adjacent side plates 3 can be fastened and connected by screws 6, thereby achieving stable support and structural strength of the transformer skeleton.

[0021] The limiting device includes an insertion rod 8 slidably connected to the outer wall of the side plate 3, a fixing groove 11 is opened on the outer wall of the end of the screw 6, the insertion rod 8 is slidably connected inside the fixing groove 11, and the end of the insertion rod 8 is fixedly connected to the slide plate 7, wherein a group of the insertion rods 8 are provided with a spring 9 on the outer wall, one end of the spring 9 is fixedly connected to the outer wall of the slide plate 7, and the other end of the spring 9 is fixedly connected to the outer wall of the side plate 3;

[0022] The end of the insertion rod 8 is provided with additional support and stability by the slide plate 7. At the same time, the setting of the spring 9 gives the entire limiting device elastic recovery ability. During operation and adjustment, the spring 9 can effectively absorb and buffer external impact force, ensuring that the insertion rod 8 and the screw 6 still maintain a good limiting effect under vibration and impact conditions.

[0023] The inner wall of the fixing groove 11 is annular, and the end of the insertion rod 8 contacts the inner wall of the fixing groove 11, wherein the lower ends of the two sets of side plates 3 are fixedly connected to the end plates 4, and the lower ends of the end plates 4 are equipped with multiple sets of pins 5;

[0024] In the utility model, the transformer skeleton is mainly composed of a connecting tube 1 and a connecting tube 2, both ends of which are fixedly connected to the side panels 3 respectively, and are connected to the inside of the connecting tube 1 and the connecting tube 2 through the through holes on the outer walls of the side panels 3, ensuring that the airflow can pass effectively, which is beneficial to the heat dissipation of the transformer. The adjacent side panels 3 are fastened and connected by multiple groups of screws 6 and fixing holes 10. The corresponding arrangement of the screws 6 and the fixing holes 10 realizes a stable connection between the two groups of side panels 3, forming the main supporting structure of the skeleton. The use of multiple screws 6 ensures the firmness and seismic resistance of the connection. In order to prevent the screw 6 from failing due to vibration or loosening during long-term use, the end of the insertion rod 8 is slidably connected to the inside of the fixing groove 11 of the screw 6. Through this design, when the screw 6 is fixed, the insertion rod 8 can slide into the fixing groove 11, which plays a limiting role, prevents the screw 6 from loosening, and ensures that the connection components will not fall off or shift in position under high vibration or impact load environments.

[0025] The end of the rod 8 is fixedly connected to the slide plate 7, and a spring 9 is installed on the side of the slide plate 7. One end of the spring 9 is fixed to the slide plate 7, and the other end is fixed to the outer wall of the side plate 3. After the screw 6 is connected, the spring 9 applies pressure to the rod 8 through the slide plate 7 to ensure that it is firmly limited in the fixing groove 11, and at the same time provides a certain elastic buffer to absorb external impact and vibration, and further prevent the screw 6 from loosening and damage to the skeleton structure.
