[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: a transformer that is easy to disassemble and has good protective performance. It is mainly aimed at improving the problems that the existing transformers need to be disassembled as a whole when disassembling, which is cumbersome. When the transformer is hit by external forces, the internal parts of the transformer may be damaged, thereby reducing the service life of the transformer, and the protective performance is not good, and the practicality is low. The specific solution is as follows: It includes a mounting base 1, a transfer base 3 and a transformer body 2. The transfer base 3 and the transformer body 2 are both arranged on the same side of the mounting base 1. The mounting base 1 is installed inside the electrical equipment cabinet. The mounting base 1 and the electrical equipment cabinet are connected by screws. The transfer base 3 is connected to the mounting base 1 through a limiting mechanism 33.

[0025] See also Figure 1 、 Figure 2 and Figure 3The transfer seat 3 includes a bearing plate 31, the transformer body 2 is fixedly mounted on the bearing plate 31, the front end surface of the bearing plate 31 is provided with a guide sleeve 32, the rear end surface of the mounting seat 1 is provided with an insertion rod 11, and the guide sleeve 32 is movably sleeved on the insertion rod 11. By inserting the guide sleeve 32 on the insertion rod 11, the position of the bearing plate 31 and the mounting seat 1 can be restricted, so that the connection and fixation of the bearing plate 31 and the mounting seat 1 are more stable.

[0026] Furthermore, the limiting mechanism 33 is fixedly mounted on the supporting plate 31, and a clamping assembly 34 is provided above the limiting mechanism 33. The limiting mechanism 33 facilitates the clamping connection of the transfer seat 3 to the mounting seat 1, further improving the efficiency of the transformer assembly and disassembly during maintenance. The provision of the clamping assembly 34 can fix the position of the transformer body 2 on the limiting mechanism 33.

[0027] See also Figure 3 and Figure 4 The limiting mechanism 33 includes a limiting plate 331, which is positioned below the support plate 31 and is shorter than the support plate 31. Guide rods 333 are provided on either side of the limiting plate 331. Positions on the mounting base 1 corresponding to the guide rods 333 are provided for insertion. Return springs 332 are movably coupled to the guide rods 333. The guide rods 333 are located on the end surface of the limiting plate 331 corresponding to the support plate 31. In the initial state, due to the elastic action of the return springs 332, the distance between the limiting plate 331 and the support plate 31 is minimized, and the guide rods 333 protrude from the support plate 31 to their maximum extent. This state facilitates the secure connection between the transfer base 3 and the mounting base 1. When the return springs 332 are stretched, the distance between the support plate 31 and the limiting plate 331 increases, and the guide rods 333 protrude from the support plate 31 to a shorter extent. This state facilitates the separation of the transfer base 3 from the mounting base 1.

[0028] It is worth noting that the upper end surface of the guide rod 333 is provided with a guide end surface, which is arranged facing the mounting seat 1. The corresponding end of the return spring 332 is fixed to the corresponding bearing plate 31 and the limit plate 331; the provision of the guide end surface can make it easier for the transfer seat 3 to be clamped on the mounting seat 1.

[0029] Furthermore, the clamping assembly 34 includes a first clamping plate 341 and a second clamping plate 342. The structures of the first clamping plate 341 and the second clamping plate 342 are as follows: Figure 3 As shown. A sliding groove is provided on the carrier plate 31 for sliding the first clamping plate 341 and the second clamping plate 342. Due to the restriction of the sliding groove, the first clamping plate 341 and the second clamping plate 342 can only slide in the horizontal direction without moving up and down.

[0030] Furthermore, the longitudinal section of the supporting plate 31 is L-shaped, and the width of the supporting plate 31 is smaller than the width of the mounting base 1. The first clamping plate 341 and the second clamping plate 342 are symmetrically clamped on both sides of the transformer body 2.

[0031] In this example, screw 1 345 and screw 2 344 are respectively provided on the opposing surfaces of the first clamping plate 341 and the second clamping plate 342. An adjusting screw sleeve 343 is provided between screw 1 345 and screw 2 344. Screw 1 345 and screw 2 344 are all aligned with the adjusting screw sleeve 343. The centers of screw 1 345, screw 2 344, and adjusting screw sleeve 343 are collinear, and screw 1 345, screw 2 344, and adjusting screw sleeve 343 are all located in front of the supporting plate 31. When the adjusting screw sleeve 343 is rotated in the forward direction, the threaded connection between the adjusting screw sleeve 343 and screw 1 345 and screw 2 344 reduces the distance between screw 1 345 and screw 2 344, thereby driving the first clamping plate 341 and the second clamping plate 342 to approach the middle at the same time, thereby clamping and fixing the transformer body 2. Similarly, when the adjusting screw sleeve 343 is rotated in the reverse direction, the first clamping plate 341 and the second clamping plate 342 can be moved from the inside to the outside at the same time. In this state, the transformer body 2 can be easily clamped and fixed.

[0032] Working principle: This kind of transformer is easy to disassemble and has good protection performance. Before use, when the adjusting screw sleeve 343 is rotated in the reverse direction, the first clamping plate 341 and the second clamping plate 342 can be moved from the inside to the outside at the same time. In this state, the distance between the first clamping plate 341 and the second clamping plate 342 is the largest, and the transformer body 2 is placed between the first clamping plate 341 and the second clamping plate 342; when the adjusting screw sleeve 343 is rotated forward, the threaded connection between the adjusting screw sleeve 343 and the screw rod 1 345 and the screw rod 2 344 is adjusted. At this time, the distance between the screw rod 1 345 and the screw rod 2 344 is reduced, and the first clamping plate 341 and the second clamping plate 342 can be driven to approach the middle at the same time, so that the position of the transformer body 2 on the transfer seat 3 can be fixed; and when the transfer seat 3 with the transformer is connected to the installation When the mounting seat 1 is installed and fixed, the return spring 332 is stretched. At this time, the distance between the supporting plate 31 and the limit plate 331 increases, and the length of the guide rod 333 protruding from the supporting plate 31 is shortened, which can facilitate the transfer seat 3 to be clamped on the mounting seat 1. When the upper and lower positions of the holes and grooves on the guide rod 333 and the mounting seat 1 correspond to each other, at this time, through the elastic action of the return spring 332, the distance between the limit plate 331 and the supporting plate 31 is the smallest, and the length of the guide rod 333 protruding from the supporting plate 31 is the longest, which can make the transfer seat 3 and the mounting seat 1 quickly fixed. The entire fixing process does not require the assistance of screws, and installation and disassembly are convenient; and through the setting of the first clamping plate 341 and the second clamping plate 342, a certain protective effect can be played on the mutual inductor, thereby ensuring the installation stability of the mutual inductor.

[0033] 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.
