[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, this utility model proposes a high-frequency transformer with voltage regulation function, including a base 1 and an insulation protection mechanism fixed to the top of the base 1. The insulation protection mechanism includes an insulation layer 11 fixed to the top of the base 1. A transformer core 21 is fixedly connected to the inner wall of the insulation layer 11. A layer of wound copper wire 7 is wound around the outer wall of the transformer core 21, and an anti-electric tape layer 8 is wound around the inner wall of the layer of wound copper wire 7. Both the anti-electric tape layer 8 and the layer of wound copper wire 7 are located on the inner wall of the insulation layer 11. A layer of wound copper wire 9 is wound around the outer wall of the insulation layer 11. The anti-electric tape layer 8 blocks the current between the layer of wound copper wire 7 and the layer of wound copper wire 9, preventing current cross-current and affecting the transformer adjustment. By setting the insulation layer 11, the current running inside the transformer is blocked by the insulation layer 11, preventing electric shock and protecting the transformer.

[0028] It should be added that, such as Figure 1 and Figure 2 As shown, the outer wall of the second layer of copper wire winding 9 is provided with a main structure. The main structure includes an anti-electric shock shell 20 fixed to the top of the base 1. A pressure block 22 is fixedly connected to the top of the anti-electric shock shell 20, and a partition 10 is provided on the inner wall of the anti-electric shock shell 20. The pressure block 22 is located at the top of the transformer core 21, and support plates 12 are fixedly connected to both sides of the outer wall of the pressure block 22. By setting the anti-electric shock shell 20, the current inside it will not be transmitted to the shell, thus preventing the possibility of electric shock. By setting the pressure block 22 to press on the top of the transformer core 21, the device can fix the entire transformer, making the transformer more stable in use.

[0029] Another point that needs to be described is, for example Figure 3 and Figure 4As shown, support plates 12 are fixedly connected to both sides of the outer wall of the base 1. A heat dissipation mechanism is provided at the top of the support plates 12. Multiple fixed seats 15 are fixedly connected to the outer wall of the pressure block 22. A heat dissipation box 14 is fixedly connected to one side of the multiple fixed seats 15. The heat dissipation mechanism includes support plates 12 fixed to both sides of the outer wall of the base 1. Multiple connecting plates 17 are fixedly connected to the top of each of the two support plates 12. Multiple heat dissipation fins 18 are fixedly connected to the outer wall of the multiple connecting plates 17. The multiple connecting plates 17 are connected to each other by connecting crossbars 19. The multiple connecting plates 17 and the heat dissipation fins 18 are all located inside the heat dissipation box 14. By setting the heat dissipation fins 18, the heat dissipated by the winding copper wire layer 7 and winding copper wire layer 9 inside the device when the current is turned on is transferred to the heat dissipation fins 18 through the connecting plates 17. The heat dissipation fins 18 and the heat dissipation box 14 dissipate the internal heat, making the heat dissipation effect of the device better.

[0030] Working principle: The anti-electric tape layer 8 isolates the copper wire layer 7 and the copper wire layer 9 from each other, preventing current leakage and affecting transformer adjustment. The insulation layer 11 blocks the current running inside the transformer, preventing electric shock and protecting the transformer. The anti-electric casing 20 prevents the internal current from being transmitted to the casing, thus preventing electric shock. The pressure block 22 presses on the top of the transformer core 21, fixing the entire transformer and making its operation more stable. The heat dissipation fins 18 transfer the heat generated by the current flowing through the copper wire layers 7 and 9 to the heat dissipation fins 18 via the connecting plate 17. The heat dissipation fins 18 and the heat dissipation box 14 then dissipate the internal heat, resulting in better heat dissipation.

[0031] Example 2

[0032] like Figure 1 and Figure 2 As shown, based on Embodiment 1, multiple extension plates 2 are fixedly connected to the outer walls of both support plates 12. A fixing seat 3 is fixedly connected to one side of each extension plate 2. A connecting terminal 4 is fixedly connected to the bottom of each fixing seat 3. A copper wire winding terminal 5 is wound around one end of the outer wall of each connecting terminal 4. One end of each copper wire winding terminal 5 is connected to the first copper wire layer 7 and the second copper wire layer 9 through a wire-insulating tube 6. By setting multiple copper wire winding terminals 5, the first copper wire layer 7 and the second copper wire layer 9 can be connected to an external power source through the copper wire winding terminals 5. By setting the wire-insulating tube 6, the exposed copper wire will not be subject to electric shock. Through the connection of the copper wire winding terminals 5 of the first copper wire layer 7 and the second copper wire layer 9, the device can adjust the internal copper wire layer by removing the copper wire winding terminals 5, thereby adjusting the internal voltage.

[0033] Additionally, a fixing rod 16 passes through the top of the support plate 12, which is fixedly connected to the pressure block 22 at the upper end, and a through rod 13 passes through the bottom of the two support plates 12, which are connected to the base 1 at the lower end. The through rod 13 is threadedly connected to the fixing rod 16. By setting the fixing rod 16 and the through rod 13, the device can be fixed to the support plate 12 and the base 1. By setting the through rod 13 and the fixing rod 16 to be threadedly connected, the device is more securely fixed.

[0034] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
