[0020] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, a transformer with a buckle comprises a transformer body 1, which is mounted on the upper end of a circuit board 2, on which two mounting through slots 6 are symmetrically provided, and on which two mounting frames 3 are symmetrically fixedly mounted. The mounting frames 3 are composed of a fixed substrate 7, a frame 8 and a mounting base rod 11, and the frame 8 is fixedly mounted on the lower end of the fixed substrate 7. There are two mounting base rods 11 that are symmetrically fixedly mounted on the inner wall of the frame 8, and a fixed buckle 4 is movably mounted on the mounting frame 3. The fixed buckle 4 is composed of a movable substrate 13, a connecting plate 15, an inserting plate 16, a clamping plate 17 and a fixing spring 18, and both the connecting plate 15 and the fixing spring 18 are fixedly mounted on one end of the movable substrate 13. There are two fixing springs 18 and they are symmetrically installed above the connecting plate 15, the plug plate 16 is fixedly installed at the lower end of the connecting plate 15, the card plate 17 is fixedly installed at the lower end of the plug plate 16, and the limiting structure 5 is movably installed on the mounting frame 3. The limiting structure 5 is composed of an L-shaped substrate 19, a T-shaped block 20 and a limiting baffle 9. The T-shaped block 20 and the limiting baffle 9 are both fixedly installed on the inner wall of the L-shaped substrate 19. When the transformer body 1 is installed and fixed to the circuit board 2, the transformer body 1 can be moved toward the circuit board 2, and the card plate 17 on the fixing buckle 4 is inserted into the installation groove 6. In the process of the card plate 17 entering the installation groove 6, the card plate 17 and the plug plate 1 are limited by the installation groove 6. 6. The connecting plate 15 and the movable substrate 13 will move inwards. At this time, the fixed spring 18 will be compressed by the movable substrate 13. After the card plate 17 passes downward through the circuit board 2, under the elastic force of the fixed spring 18, the card plate 17, the plug plate 16, the connecting plate 15 and the movable substrate 13 will move outwards. At this time, the card plate 17 will be stuck at the lower end of the circuit board 2, and the movable substrate 13 will contact the outer inner wall of the frame 8. At this time, the transformer body 1 is fixed to the upper end of the circuit board 2, and then the limiting structure 5 is pushed downwards, so that the limiting baffle 9 is inserted into the frame 8, and the limiting baffle 9 is located on the inner side of the movable substrate 13. At this time, under the obstruction of the limiting baffle 9, the card plate 17 and the plug plate 16, the connecting plate 15 and the movable substrate 13 will not move inward after being subjected to force. Finally, by arranging a mounting frame 3 on the transformer main body 1 and arranging a fixing buckle 4 on the mounting frame 3, the installation steps of the transformer main body 1 can be simplified, so that the installation of the transformer main body 1 can be more convenient, and thus the installation efficiency of the transformer main body 1 can be finally improved. By arranging a limiting structure 5, the movable substrate 13, the connecting plate 15, the plug plate 16 and the card plate 17 on the fixing buckle 4 can be blocked and limited, so as to prevent the movable substrate 13, the connecting plate 15, the plug plate 16 and the card plate 17 on the fixing buckle 4 from moving when the transformer main body 1 is fixed on the circuit board 2 by the fixing buckle 4.

[0022] Further, the fixed substrate 7 on the mounting bracket 3 is fixedly installed at one end of the transformer body 1. A communication slot 10 is opened at the lower end of the frame 8, and a T-shaped guide rail slot 12 is opened at the outer end of the frame 8. The moving substrate 13 on the fixed buckle 4 is located inside the frame 8. Two mounting holes 14 are symmetrically opened on the moving substrate 13, and the moving substrate 13 is slidably installed on the mounting base rod 11 through the mounting holes 14. The fixed spring 18 is also sleeved on the mounting base rod 11. The connecting plate 15 on the fixed buckle 4 passes through the communication slot 10. The insertion plate 16 can be inserted into the mounting through slot 6, and the clamping plate 17 can be clamped at the lower end of the circuit board 2. When the clamping plate 17 passes through the mounting through slot 6, it is limited and blocked by the mounting through slot 6, and the moving substrate 13, the connecting plate 15, the insertion plate 16 and the clamping plate 17 will move inward as a whole. At this time, the fixed spring 18 will be compressed by the moving substrate 13. When the clamping plate 17 passes through the mounting through slot 6, under the elastic force of the fixed spring 18, the moving substrate 13, the connecting plate 15, the insertion plate 16 and the clamping plate 17 will move outward until the moving substrate 13 abuts against the inner wall of the outer side of the frame 8. When the moving substrate 13 moves inward or outward, it will slide on the mounting base rod 11.

[0023] Further, the L-shaped substrate 19 on the limiting structure 5 is buckled on the frame 8. The limiting baffle 9 can be inserted into the frame 8. The T-shaped block 20 is slidably installed in the T-shaped guide rail slot 12. Before installing the transformer body 1 on the circuit board 2, it is necessary to make the limiting baffle 9 on the limiting structure 5 above the frame 8, that is, to make the limiting baffle 9 not block the inward sliding of the moving substrate 13 on the mounting base rod 11. After the transformer body 1 is fixed on the circuit board 2 by the fixed buckle 4, the limiting structure 5 can be moved downward, so that the limiting baffle 9 is inserted inside the moving substrate 13, thereby blocking the moving substrate 13. When the limiting structure 5 moves downward or upward, the T-shaped block 20 will move in the T-shaped guide rail slot 12.
