However, the lack of a function to lock the position of the drive panel after adjustment makes it easy for the position of the drive panel to change during use, affecting the safety of subsequent electrical appliances.

[0004] Therefore, we propose a built-in single-phase to three-phase converter to address the problems mentioned above. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-5 A built-in single-phase and three-phase converter includes a housing 1, with insulators 2 fixedly installed on both sides of the housing 1, a base 3 installed at the bottom of the housing 1, stabilizing components 4 arranged near the bottom of the base 3, a U-shaped block 7 installed on the other side of one insulator 2, a conductor B8 arranged in the inner cavity of the U-shaped block 7 (conductor B8 can be connected to an external power supply line), and an adjusting component 5 arranged on the conductor B8, and several conductors A6 fixedly installed on one side of the other insulator 2 (several conductors A6 can be connected to external power transmission lines respectively).

[0026] The adjustment assembly 5 includes an insulating rod 52 rotatably connected to the bottom of the inner cavity of the U-shaped block 7 and a fixing groove 51 fixedly installed on the top of the outer shell 1 near one side. The top end of the insulating rod 52 passes through the top of the conductor B8, and the top end of the insulating rod 52 movably passes through the top of the inner cavity of the U-shaped block 7, the outer shell 1 and the fixing groove 51, and is fixedly installed on a drive disk 53. An adjustment knob 54 is fixedly installed at the middle position of the top of the drive disk 53 (anti-slip pads are fixedly installed on both sides of the adjustment knob 54). Several blind holes 55 are opened on the outer periphery of the drive disk 53 near one side, and a plug rod 56 is movably inserted into the inner cavity of an adjacent blind hole 55. A movable block 57 is fixedly installed at one end of the plug rod 56. A limit telescopic rod A58 is fixedly installed on one side of the movable block 57 near the front and rear sides. An L-shaped block 59 is fixedly installed at one end of the limit telescopic rod A58.

[0027] Specifically, when adjusting conductor B8, with the cooperation of adjusting component 5, after adjusting the position of drive disk 53, the toggle block 571 can be released. Under the elastic force of return spring 581, the plug 56 fixed on movable block 57 can be inserted into the inner cavity of adjacent blind hole 55, which can lock the position of drive disk 53, prevent the position of drive disk 53 from changing, provide stable AC power, and improve the safety of electrical appliance use.

[0028] The outer periphery of the limiting telescopic rod A58 is movably fitted with a return spring 581, and the two ends of the return spring 581 are fixedly connected to the L-shaped block 59 and the movable block 57 respectively; the top of the movable block 57 is fixedly installed with a toggle block 571.

[0029] Specifically, by setting a reset spring 581, the insertion rod 56 can be stably inserted into the inner cavity of the blind hole 55, thereby improving the limiting effect on the drive disk 53.

[0030] Several display buttons 511 are fixedly installed on the top of the fixed slot 51 near the rear side. The display buttons 511 are arranged in a circular array with the top center of the drive disk 53 as the center.

[0031] Specifically, the position of the adjustment drive disk 53 can be displayed by setting the display button 511.

[0032] Several conductors A6 are arranged linearly from front to back, and the length of conductors A6 located on the front and back sides is greater than the length of conductor A6 located in the middle.

[0033] Example 2

[0034] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 4The stabilizing component 4 includes a connecting block 41 fixedly installed on the bottom of the base 3 near one side and a limiting groove opened at the bottom of the connecting block 41. A protrusion 42 is movably inserted into the inner cavity of the limiting groove. Rectangular grooves are opened on both sides of the inner cavity of the limiting groove. A suction cup 43 is fixedly installed at the bottom of the protrusion 42. Slots are opened on both sides of the protrusion 42. A T-shaped plug 44 is movably inserted into the inner cavity of each slot. A threaded rod 45 is fixedly installed at the middle position of the side of the T-shaped plug 44 that is far away from each other. A threaded tube 46 is threadedly connected to the outer periphery of the threaded rod 45. A knob 47 is fixedly installed at the end of the threaded tube 46 that is far away from each other.

[0035] Specifically, when placing the outer casing 1, with the cooperation of the stabilizing component 4, the outer casing 1 can be adsorbed in the required position, thereby improving the stability of the outer casing 1.

[0036] Several anti-slip pads are fixedly installed on the outer periphery of the knob 47, and the anti-slip pads are all made of rubber.

[0037] Specifically, by setting several anti-slip pads, slippage can be prevented when driving knob 47.

[0038] On the side of the T-shaped insert 44 that is far apart from each other, near the top and bottom, a limiting telescopic rod B441 is fixedly installed, and the ends of the limiting telescopic rod B441 are fixedly connected to the inner wall of the adjacent rectangular groove.

[0039] Specifically, the T-shaped insert 44 can be limited when it moves by setting the limit telescopic rod B441.

[0040] Working Principle: When adjusting conductor B8, the movable block 57 can be pushed to one side by the toggle block 571, which compresses the limiting telescopic rod A58 and the return spring 581. This allows the insertion rod 56 fixed on the movable block 57 to move away from the inner cavity of the adjacent blind hole 55. Then, the drive disk 53 can be rotated by the adjustment knob 54. The adjustment position can be displayed by the display knob 511. During the rotation of the drive disk 53, the insulating rod 52 fixed on the drive disk 53 can rotate, which in turn allows conductor B8 to rotate, making contact with the adjacent conductor A6 and outputting corresponding AC power. After the adjustment is completed, the toggle block 571 can be released, and the insertion rod fixed on the movable block 57 can be released under the elastic force of the return spring 581. 56 is inserted into the inner cavity of the adjacent blind hole 55, which can lock the position of the drive disk 53, prevent the position of the drive disk 53 from changing, provide stable AC power, and improve the safety of electrical appliances. By setting the suction cup 43, the outer shell 1 can be adsorbed in a suitable position to prevent it from being accidentally tipped over and damaged. When the suction cup 43 needs to be replaced, the adjacent knob 47 can be rotated to rotate the threaded tube 46 fixed on the adjacent knob 47. The threaded rod 45 connected to the inner cavity of the threaded tube 46 can move the adjacent T-shaped plug 44 to the opposite side under the limit of the two adjacent limit telescopic rods B441, thereby moving the T-shaped plug 44 away from the inner cavity of the adjacent slot, which facilitates the disassembly and replacement of the suction cup 43 after long-term use and improves the stability of the subsequent placement of the outer shell 1.
