DETAILED DESCRIPTION

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

Please refer to Figures 1-4. The utility model is an oil-immersed transformer that is easy to install, including an oil-immersed transformer body 1 and a fixing frame 2. A hanging frame 3 is fixedly installed on the outer wall of the oil-immersed transformer body 1, and the hanging frame 3 is an inverted U-shaped structure. The fixing frame 2 includes a front plate 4 and a side plate 5. The side plate 5 is slidably installed on both sides of the front plate 4. The side plate 5 is provided with a plurality of fixing holes 19. The upper and lower ends of the front plate 4 are fixedly installed with a guide frame 6. The guide frame 6 is an arc structure. A guide groove 8 is opened on the guide frame 6. One end of the hanging frame 3 is inserted into the guide groove 8.

When the oil-immersed transformer body 1 is suspended on the guide frame 6 through the hanger 3, it is necessary to facilitate sliding on the guide frame 6 to adjust the installation position of the oil-immersed transformer. A part of the hanger 3 is a vertical plate 12, and another part of the hanger 3 is a cylinder 13. The bottom end of the cylinder 13 is installed with a limit nut 15 through a threaded structure. The joint between the limit nut 15 and the guide frame 6 is a toothed structure. The top of the hanger 3 is in contact with the guide frame 6. The front side of the vertical plate 12 is provided with a slot 14. An insertion rod 18 is fixedly installed on the outer wall, the insertion rod 18 is matched with the slot 14, and the top two ends of the insertion rod 18 are connected to the vertical plate 12 by a bolt structure. According to the above structure, a part of the bracket 3 is provided with a cylinder 13, and the cylinder 13 is inserted into the guide groove 8 of the guide frame 6. The cylinder 13 structure is more convenient for sliding in the guide groove 8. A slot 14 is provided on the vertical plate 12, and the oil-immersed transformer uses the insertion rod 18 to be inserted into the slot 14, so that the disassembly and assembly of the oil-immersed transformer body 1 is more convenient.

When the fixing frame 2 is assembled with the device for fixing the oil-immersed transformer body 1, it is necessary to adjust the displacement of the side plate 5 on the fixing frame 2 according to the size of the device. A sliding groove 9 is provided on the rear side of the front plate 4, and a bidirectional threaded screw 10 is installed in the sliding groove 9. The side plate 5 is sleeved on the bidirectional threaded screw 10 through a slider. One end of the bidirectional threaded screw 10 passes through the front plate 4, and a rotating rod 17 is fixedly installed on the threaded screw at this end. Slide grooves 11 are provided at the upper and lower ends of the rear side of the front plate 4. The side plate 5 is slidably connected to the slide groove 11 through the slide rod. A bearing plate 7 is fixedly installed at the bottom of the front plate 4. According to the above structure, the bidirectional threaded screw 10 is rotated, and the side plates 5 on both sides of the front plate 4 will slide toward or against each other to adjust the distance between the two side plates 5. When the distance between the two side plates 5 matches the device for fixing the oil-immersed transformer body 1, a bolt structure can be used to penetrate the fixing holes 19 on the side plates 5 and fix them thereto.

When the oil-immersed transformer body 1 is disassembled, assembled and transported, it is required that the oil-immersed transformer body 1 has a force application point that is convenient for applying force. The preferred solution in the utility model is that the bottom and top of both sides of the oil-immersed transformer body 1 are provided with hanging rods 16, and the hanging rods 16 are used as force application points.

The oil-immersed transformer body 1 which is easy to install is used to rotate the bidirectional threaded screw 10 to adjust the spacing between the side plates 5 on both sides of the front plate 4. When the spacing between the two side plates 5 matches the device for fixing the oil-immersed transformer body 1, a bolt structure can be used to penetrate the fixing holes 19 on the side plates 5 to be fixedly connected thereto. Then, the hanger 3 is set as a part of the cylinder 13 to be inserted into the guide groove 8 of the guide frame 6. The cylinder 13 structure is more convenient to slide in the guide groove 8. After the position adjustment of the oil-immersed transformer body 1 is completed, the limit nut 15 is tightly fitted with the guide frame 6 using the tooth structure. At the same time, the top of the hanger 3 is fitted with the guide frame 6 to fix the oil-immersed transformer body 1. A slot 14 is set on the vertical plate 12. The oil-immersed transformer uses the insertion rod 18 to insert the slot 14, so that the disassembly and assembly of the oil-immersed transformer body 1 is more convenient. At the same time, the bottom of the front plate 4 supports the oil-immersed transformer body 1 through the bearing plate 7, further ensuring the firmness of the installation of the oil-immersed transformer body 1.

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