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

[0024] Example: See Figure 1-5 The present invention provides a technical solution: an outdoor seismic-resistant combined transformer. This solution aims to improve the problem that when disassembling the transformer, multiple screws need to be removed, which is not only time-consuming and labor-intensive, but also easily rusts due to environmental influences, making disassembly inconvenient. Furthermore, the transformer has no shock-absorbing components, which affects the stability of the transformer. The specific solution is as follows: It comprises a mounting base 1 and a transformer body 2. The transformer body 2 is fixedly mounted above the mounting base 1, and the mounting base 1 is fixed to the ground by expansion screws.

[0025] See also Figure 1 and Figure 2 Mounting base 1 includes a mounting plate 11 and side panels 12. These panels are fixedly mounted and perpendicular to mounting base 1. Side panels 12 are symmetrically positioned on the front and rear sides of mounting plate 11. Connectors 13 are positioned on the opposing sides of adjacent side panels 12 and are distributed in a directional pattern on mounting plate 11. The placement of connectors 13 allows for accurate positioning of transformer body 2 within mounting base 1, ensuring accurate installation of transformer body 2.

[0026] See also Figure 2 and Figure 5 The connector 13 has a limit rod 14 movably connected to its center. An adjustment rod 16 is movably connected to the upper end of the limit rod 14. A return spring 17 is sleeved on the adjustment rod 16. The return spring 17 maintains a certain distance between the adjustment rod 16 and the limit rod 14 in the initial state. A support plate 18 is provided on the adjustment rod 16, and the return spring 17 is located above the support plate 18. The corresponding side of the return spring 17, the support plate 18, and the limit rod 14 are welded together.

[0027] Furthermore, a tapered end 19 is provided at the lower end of the adjustment rod 16, and a limit plate 15 is provided in an annular shape on the outer side of the limit rod 14. The limit plate 15 is movably connected to the adjustment rod 16; the effective length of the limit plate 15 is less than the inner radius of the limit rod 14, and the outer end of the limit plate 15 is provided with an inclined surface. Due to the fit between the tapered end 19 and the limit plate 15, in the initial state, the tapered end 19 can cause the outer end of the limit plate 15 to protrude from the limit rod 14 due to the elastic action of the return spring 17. After the return spring 17 is compressed, the limit plate 15 can be retracted into the limit rod 14. In this state, the upward position of the transformer body 2 can be easily limited, and no screws are required for fixing, making it easy to disassemble and install.

[0028] Furthermore, the centers of the adjusting rod 16 and the limiting rod 14 are collinear, and the length of the adjusting rod 16 is less than the length of the limiting rod 14. The limiting rod 14 is provided with a hole groove in the shape of a ring for inserting the limiting plate 15, and the hole groove is connected to the limiting rod 14 inside and outside. The limiting plate 15 is arranged in a ring shape on the outside of the conical end 19, and the limiting plate 15 and the conical end 19 are fitted with an inclined surface. A fixed channel steel 21 is provided at the lower end of the transformer body 2. After pressing the adjusting rod 16, the adjusting rod 16 can drive the conical end 19 to move from top to bottom. At this time, through the fitting action of the conical end 19 and the limiting plate 15, the adjacent limiting plates 15 can be moved from outside to inside at the same time, thereby causing the limiting plate 15 to retract into the inside of the limiting rod 14, thereby causing the limiting plate 15 to break away from the position restriction of the fixed channel steel 21.

[0029] Furthermore, lifting rings 22 are provided on the front and rear sides of the upper end of the fixed channel steel 21 . The lifting rings 22 can lift the entire transformer body 2 . The lifting rings 22 are distributed in a square shape, which can improve the support points of the transformer body 2 .

[0030] In this example, a guide hole 23 for inserting the limit rod 14 is opened at the outer end of the fixed channel steel 21, and the guide hole 23 is arranged outside the adjacent lifting ring 22. The fixed channel steel 21 is movably sleeved on the top of the plug-in component 13, and the fixed channel steel 21 and the side wall of the plug-in component 13 are in contact.

[0031] Working principle: When installing this type of outdoor seismic-resistant combined transformer, first, the mounting base 1 is fixed to the ground by expansion screws; secondly, the transformer body 2 is clamped and fixed to the mounting base 1; during operation, the fixed channel steel 21 is clamped and connected to the corresponding plug-in piece 13. At this time, the limit rod 14 is inserted into the corresponding guide hole 23 on the fixed channel steel 21. During the process of the limit rod 14 being inserted into the fixed channel steel 21, the limit plate 15 arranged in a ring shape on the outside of the limit rod 14 can be pushed to move from outside to inside at the same time; thereby, the reset conical end 19 drives the adjusting rod 16 to move from bottom to top, compressing the reset spring 17, thereby facilitating the connection between the fixed channel steel 21 and the plug-in piece 13; while facilitating the fixing of the transformer body 2 on the mounting base 1, through the setting of the reset spring 17, the seismic-resistant effect of the combined transformer can be effectively improved by the elastic force of the reset spring 17 during the vibration of the combined transformer.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
