[0025] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0026] According to an embodiment of this utility model, a transformer body positioning structure is provided. Please refer to [link / reference]. Figures 1 to 4 The transformer includes a positioning pin 5 and a mounting hole 9. The mounting hole 9 is located on the support plate 4 at the bottom of the transformer body 3. The mounting hole 9 includes a mounting end 901 and a positioning end 902. The diameter of the mounting end 901 is larger than the diameter of the positioning end 902. The positioning pin 5 is configured as a variable diameter structure. Its small diameter end 501 is located on the bottom surface 1 of the transformer body, and its large diameter end 502 is provided with a locking nut 6. The connection between its small diameter end 501 and its large diameter end 502 forms a positioning surface 503.

[0027] After the positioning pin 5 passes through the mounting end 901 of the mounting hole, it pushes the support plate 4 to make the small diameter end 501 of the positioning pin slide to the positioning end 902 of the mounting hole, and the positioning surface 503 cooperates with the upper surface of the support plate 4 for a stop.

[0028] It should be noted that by setting the positioning pin 5 and the mounting hole 9, the positioning pin 5 has a positioning surface 503, and the mounting hole 9 has a mounting end 901 and a positioning end 902. After the positioning pin 5 passes through the mounting end 901 of the mounting hole, it pushes the support plate 4 to make the small diameter end 501 of the positioning pin slide to the positioning end 902 of the mounting hole, so that the positioning surface 503 stops and cooperates with the upper surface of the support plate 4. At the same time, the locking nut 6 is used to further lock it. The positioning pin 5, the mounting hole 9 and the locking nut 6 cooperate to rigidly position the bottom of the transformer body 3, prevent the transformer body 3 from shifting in the vertical direction, and avoid wear and deformation of some parts due to displacement.

[0029] In the transformer body positioning structure of this embodiment, please refer to... Figures 1 to 4 The mounting end 901 of the mounting hole 9 is configured as a circular hole structure, which is clearance-fitted with the large diameter end 502 of the positioning pin. The positioning end 902 of the mounting hole is configured as an oblong hole structure, which is clearance-fitted with the small diameter end 501 of the positioning pin. The junction of the mounting end 901 and the positioning end 902 adopts an arc transition to guide the small diameter end 501 of the positioning pin to slide smoothly to the positioning end 902 of the mounting hole.

[0030] Furthermore, the support plate 4 is provided with two mounting holes 9, and the two mounting holes 9 are located on different sides of the transformer body 3. Correspondingly, two positioning nails 5 are provided on the bottom surface 1 of the transformer box to position the transformer body 3 from two directions.

[0031] Furthermore, the diameter of the positioning end 902 is larger than the diameter of the small diameter end 501 and smaller than the diameter of the large diameter end 502. At the same time, the thickness of the support plate 4 is the same as the height of the small diameter end 501.

[0032] It should be noted that the cross-section of the positioning pin 5 is set to be circular, and the mounting end 901 with a circular hole structure is matched with it. The diameter of the mounting end 901 is larger than the diameter of the large diameter end 502, so as to achieve smooth assembly between the mounting end 901 and the positioning pin 5. During the process of pushing the support plate 4 along the direction parallel to the positioning end 902, the small diameter end 501 slides from the mounting end 901 into the positioning end 902, and finally slides to the end of the positioning end 902. At this time, the positioning surface 503 abuts against the upper surface of the support plate 4 to achieve a stop fit and prevent the transformer body 3 from shifting in the vertical direction.

[0033] In the transformer body positioning structure of this embodiment, please refer to... Figures 1 to 4 The large-diameter end 502 of the positioning pin includes a smooth section 5021 and a threaded section 5022. A washer 11 is sleeved around the smooth section 5021. The threaded section 5022 is threadedly engaged with the locking nut 6. The washer 11 is located between the upper surface of the support plate 4 and the locking nut 6.

[0034] It should be noted that the gasket 11 adopts a ring structure, which is sleeved on the outer periphery of the smooth segment 5021, and then the locking nut 6 is assembled to press the gasket 11 against the upper surface of the support plate 4 to achieve locking.

[0035] In the transformer body positioning structure of this embodiment, please refer to... Figures 1 to 4 The gasket 11 is provided with a limiting post 13, and the support plate 4 is provided with a limiting hole 10 corresponding to the limiting post 13.

[0036] In use, after installing the gasket 11, the limiting post 13 is embedded inside the limiting hole 10 to limit the relative position of the positioning pin 5 and the mounting hole 9.

[0037] Furthermore, the gasket 11 is provided with a receiving cavity 12, and the top of the limiting post 13 is slidably disposed inside the receiving cavity 12. A compression spring 14 is provided between the receiving cavity 12 and the top of the limiting post 13. The compression spring 14 is used to buffer the preload applied to the support plate 4 by the locking nut 6, ensuring that the locking nut 6, the gasket 11 and the support plate 4 are in close contact, and preventing loosening due to vibration or external force.

[0038] In the transformer body positioning structure of this embodiment, please refer to... Figures 1 to 6 It also includes a pull plate 7, the bottom of which is connected to the top of the transformer body 3, and the top of which is connected to the top surface 2 of the transformer housing via a screw 8. The pull plate 7 and the screw 8 are used to position the top of the transformer body 3.

[0039] Furthermore, the pull plate 7 is provided with a bushing 15 that is threadedly engaged with the screw 8. A locating pin 16 is provided between the bushing 15 and the screw 8. Specifically, the locating pin 16 is set perpendicular to the screw 8. In use, after the screw 8 passes through the top surface 2 of the transformer housing, it is embedded inside the bushing 15. The screw 8 is turned to make it firmly connected to the bushing 15. At this time, the locating pin 16 is then passed through the bushing 15 and the screw 8 in sequence to prevent relative rotation between the bushing 15 and the screw 8, effectively improving the connection stability.

[0040] Specifically, the bushing 15 has an upper mounting cavity 1501 and a lower mounting cavity 1502 that are connected to each other. The lower mounting cavity 1502 is threaded to the screw 8. The upper mounting cavity 1501 has a plurality of through holes 1503 for installing the positioning pin 16 on its cavity wall. Correspondingly, the screw 8 also has a screw through hole. The diameter of the upper mounting cavity 1501 is larger than the diameter of the lower mounting cavity 1502, which makes it easier to observe the relative position of the through holes 1503 and the screw through holes, and smoothly completes the assembly of the positioning pin 16.

[0041] According to an embodiment of this utility model, a transformer is provided; please refer to [link / reference].Figures 1 to 6 This includes the transformer body positioning structure.

[0042] It should be noted that by using the transformer body positioning structure to position the top and bottom of the transformer body 3 respectively, the sturdiness and reliability of the transformer body 3 assembly are ensured, and problems such as displacement of the transformer body 3 or loosening of fasteners caused by improper positioning during transportation are eliminated.
