[0016] See also Figure 1-2 The utility model provides a technical solution: a box frame structure of a box-type transformer, including a mounting beam frame and a limiting mechanism, the mounting beam frame is composed of a left beam frame 1 and a right beam frame 2, the left beam frame 1 and the right beam frame 2 are connected by a stretching rod 3, and a horizontal slide groove 4 is arranged on the relatively inner walls of the left beam frame 1 and the right beam frame 2, a slide plate 5 is slidably installed in the slide groove 4, and a limiting mechanism is installed on the slide plate 5;

[0017] The limiting mechanism is composed of a spring shaft mounting seat 6, a return spring shaft 7 and a pad 8, wherein the spring shaft mounting seat 6 is fixedly mounted on the left and right ends of the slide plate 5, respectively, and the bottom end of the spring shaft mounting seat 6 is connected to the pad 8 through the return spring shaft 7;

[0018] There are two mounting beams, which are horizontally arranged from top to bottom. The upper and lower mounting beams are connected by a linear guide rail 9, and pads 8 are fixedly connected to the left and right ends of the slide 5 of the mounting beam at the bottom.

[0019] Bolt holes 10 are provided on both the left beam frame 1 and the right beam frame 2, so as to facilitate the adjustment of the distance between the left beam frame 1 and the right beam frame 2 and fix them in the box body by bolts.

[0020] The mounting beam is slidably connected to the linear guide rail 9, and a bolt hole 10 is provided at the top end of the linear guide rail 9. When loading and unloading the transformer, the upper mounting beam performs corresponding lifting and displacement movements to provide convenience. The bottom mounting beam is located at the bottom of the box, and the top end of the linear guide rail 9 is fixed to the top surface of the box through the bolt hole 10 and the external bolts.

[0021] A limit seat 11 is provided on the outer edge of the left beam frame 1 , and a limit plate 12 corresponding to the limit seat 11 is installed on the slide plate 5 .

[0022] Working principle:

[0023] In this solution, the entire structure is divided into a mounting beam and a limiting mechanism, wherein the mounting beam serves as an external bracket for fixing the transformer in the box, and is used to adapt transformers of different widths to be installed and fixed in the box, and the limiting mechanism is used to adapt transformers of different heights to be fixed and assembled in the box;

[0024] The number of mounting beams is divided into two, and each mounting beam is composed of a left beam 1 and a right beam 2 connected by a stretching rod 3, so that the distance between the left beam 1 and the right beam 2 can be adjusted conveniently by the stretching rod 3, and is used to adapt to the left and right side limit assembly of transformers of different widths, and then the bolts are connected externally through the bolt holes 10 on the left beam 1 and the right beam 2 and then fixed to the inner wall of the box, so as to achieve the fixing effect after the distance between the left beam 1 and the right beam 2 is adjusted;

[0025] A slide plate 5 is slidably mounted on the inner walls of the left beam frame 1 and the right beam frame 2 facing each other through a slide groove 4. The slide plate 5 slides horizontally left and right in the slide groove 4. The limit plate 12 on the slide plate 5 can prevent the slide plate 5 from completely sliding out of the slide groove 4 when sliding, and the limit plate 12 will be resisted by the limit seat 11;

[0026] The bottom surfaces of the left and right sides of the transformer are supported by the pads 8 of the slide plate 5 on the mounting beam at the bottom. The two mounting beams slide through the linear guide rails 9. The bottom mounting beam is assembled at the bottom end of the transformer box. The mounting beam at the upper layer is manually slid down until the pads 8 at the bottom end of the reset spring shaft 7 on the upper mounting beam are pressed against the upper surfaces of the left and right sides of the transformer. At this time, the pads 8 act as a pressure plate. Then the upper mounting beam is fixed in the box through the bolt holes 10 and the external bolts. The top of the pads 8 at the upper mounting beam is connected to the spring shaft 7 and the spring shaft mounting seat 6 through the reset spring shaft 7, so that the pads 8 at the upper mounting beam have a buffering effect. At the same time, it is also convenient to disassemble the upper mounting beam. Through the spring force of the reset spring shaft 7, the upper mounting beam is displaced upward from the linear guide rail 9 by a small distance after the bolts are removed, which facilitates the rapid disassembly process of the transformer in the entire assembly structure.
