[0021] Reference Figure 1-4 The utility model provides a transformer structure that is convenient for maintenance, including a transformer body 1, four support shells 10 are fixedly connected to the bottom end of the transformer body 1, and support plates 3 are slidably connected to the inside of the four support shells 10, and the front and rear ends of the transformer body 1 are fixedly connected to fixed shells 4, and the inside of the fixed shells 4 is slidably connected to a support frame 5, and the inside of the support frame 5 is fixedly connected to a fixed frame 6, and a plug hole 13 is opened on the left end surface of the support frame 5, and plug-in components are installed on the front and rear ends of the support frame 5, and the plug-in components are connected to the support frame 5 through the plug hole 13 and are used to support the fixed frame 6; when working, after putting the ladder at a suitable position between two poles, the staff can climb up the ladder and The hand-held fixing frame 6 is used to provide the staff with a supporting point, so that the staff can perform maintenance work on the outer end of the transformer body 1 more stably. In addition, the support plate 3 is pulled out from the support shell 10, and the support plate 3 is used to temporarily store the maintenance tools carried by the staff, which reduces the burden on the staff and does not require the staff to carry the maintenance tools all the time. When there is a certain distance between the ladder and the transformer body 1, the staff can step on the ladder with one foot and put the other foot on the supporting plate 3, use the supporting plate 3 to provide a supporting point for the staff's feet, and support the fixing frame 6 with one hand, which is convenient for the staff to perform maintenance work on the transformer body 1 that is far away.

[0022] The plug-in assembly includes an insertion rod 12, a movable plate 14, a spring 16, a vertical plate 15 and a pull rod 9. The front and rear ends of the transformer body 1 are fixedly connected with the vertical plate 15. The interior of the vertical plate 15 is fixedly connected with a guide rod 11. The circumferential surface of the guide rod 11 is slidably connected with the movable plate 14. The end of the movable plate 14 close to the support frame 5 is fixedly connected with the insertion rod 12. The insertion rod 12 is connected to the support frame 5 through the socket 13. The interior of the vertical plate 15 is slidably connected with the pull rod 9. The pull rod 9 is fixedly connected to the movable plate 14. The circumferential surface of the pull rod 9 is sleeved with a spring 16. One end of the spring 16 is fixedly connected to the vertical plate 15, and the other end of the spring 16 is fixedly connected to the movable plate 14. During operation, pulling the pull rod 9 to move away from the support frame 5 will drive the movable plate 14 to move along the guide rod 11, and at the same time the spring 16 will be stretched. As the movable plate 14 moves, the insertion rod 12 will also be driven to move. Until the insertion rod 12 is separated from the insertion hole 13, the support frame 5 can be pressed downward toward the inside of the fixed shell 4, so that the support frame 5 can drive the fixed frame 6 to move downward. In this way, when maintenance work is no longer required, the overall equipment can occupy less space. When it needs to be used again, the fixed frame 6 is moved upward to drive the insertion hole 13 to move until the insertion hole 13 moves to the position corresponding to the insertion rod 12. Under the action of the spring 16, the pull rod 9 is inserted into the insertion hole 13, so that the support frame 5 is stably located in the fixed shell 4, and finally the fixed frame 6 is stably in this position, which is convenient for the staff to use.

[0024] Furthermore, the four support shells 10 and the support plates 3 are respectively oriented to the front, back, left, and right ends of the transformer body 1. When the staff performs maintenance work in four different directions, the support plates 3 are provided in the four directions for the convenience of the staff.

[0025] Furthermore, the end surface of the support plate 3 is in an inverted L-shape. During operation, the L-shaped support plate 3 facilitates the staff to pull the support plate 3 to move along the support shell 10, thereby facilitating the adjustment of the position of the support plate 3.

[0026] Furthermore, a limiting hole 7 is formed on one end face of the fixed shell 4 away from the transformer body 1, and a limiting block 8 is slidably connected inside the limiting hole 7, and the limiting block 8 is fixedly connected to the support frame 5. During operation, while the support frame 5 stably moves along the fixed shell 4, the support frame 5 can also be prevented from being separated from the fixed shell 4.

[0027] Furthermore, the side end surfaces of the plurality of support shells 10 are provided with sliding holes, the interior of the sliding holes is slidably connected with a sliding block, and the sliding block is fixedly connected to the support plate 3. During operation, the existence of the sliding holes and the sliding blocks can prevent the support plate 3 from being separated from the support shell 10.
