Description

Technical Field

[0001] The utility model belongs to the technical field of transformer accessories, and in particular relates to a handheld transformer rotating handle. Background Art

[0002] In the induction heating power supply equipment, the main unit of the induction heating power supply adopts a cabinet structure, and the output part adopts a flexible cable output method. The schematic diagram of the output part of the induction heating power supply in the prior art is as follows: Figure 1 As shown, it includes a flexible cable 11, a small transformer 12 arranged in front of the end of the flexible cable 11, and an induction heating coil 13 installed in front of the small transformer 12. The rear end of the flexible cable 11 is connected to the host of the induction heating power supply (not shown in the figure). When in use, the flexible cable 11 can be powered on to achieve induction heating of the target workpiece. In actual use, in a simple use scenario, the output part can be installed on an adjustable three-dimensional table, and the target workpiece can be heated after the position is adjusted; it can also be installed on a manipulator, and the manipulator can drive the target workpiece to achieve precise heating; in complex working conditions, the operator needs to hold the small transformer 12 to heat the target workpiece, but when the target workpiece is heated in a handheld manner, the weight of the entire output part is between 5kg and 20kg, and the handheld time will be fatigued, and the target workpiece has various position angles, and the device needs to be rotated frequently to adapt to the angles of different target workpieces. The induction heating power output device in the prior art cannot meet the handheld application scenario, so the transformer needs to be fixed in a handheld handle. Because the small transformer 12 is pear-shaped, it is not suitable for standard bearings and therefore cannot be used with most handles available on the market. Furthermore, because there is an electromagnetic field around the transformer when it is working, the rotating handle of the handheld transformer cannot be made of metal material, firstly because it is too heavy and secondly because it is easily heated by induction, while most handles on the market are made of metal. Finally, because most handles on the market do not have a rotating function, they cannot be adapted to flexibly adjust workpieces at different angles. Utility Model Content
