However, the heating coil is often complex in structure, with wires and other components connected in the casing, making it inconvenient to move the heating coil and affecting heating efficiency and operational flexibility.

[0005] In summary, existing portable high-frequency induction heaters suffer from complex structures and inconvenient operation when moving the heating coils, which affects heating efficiency and flexibility during operation. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide a portable high-frequency induction heater to solve the technical problems of existing portable high-frequency induction heaters having complex structures and inconvenient operation when moving the heating coil, which affect the heating efficiency and flexibility during operation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a movable high-frequency induction heating machine, including a housing, a coil for heating a metal rod body is arranged laterally on the front of the housing, and a rotating arm is also included. The rotating arm is rotatably connected to both sides of the bottom of the housing. Inclined sliding grooves are arranged at intervals along the length of the rotating arm. An adjusting shaft is slidably connected in the sliding groove. A guide roller for supporting the metal rod body is rotatably connected to the end of the adjusting shaft.

[0008] By adopting the above technical solution, rotating arms are connected to both sides of the chassis, and guide rollers set on the rotating arms support the metal rod, allowing the metal rod to pass through the coil in a horizontal direction for heating.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] First embodiment: A portable high-frequency induction heater, please refer to [link / reference]. Figure 1-6 The device includes a housing 1, on the front of which a coil 10 for heating the metal rod body 11 is arranged horizontally. Inside the housing 1 is a control module for controlling the heating parameters of the coil 10. The heating temperature, time and power can be precisely adjusted through a digital operation interface. This application does not improve its specific adjustment principle, and its specific working principle will not be described in detail here.

[0034] It also includes a rotating arm 2, which is rotatably connected to both sides of the bottom end of the housing 1. The rotating arm 2 is provided with inclined shifting grooves 201 at intervals along its length. An adjusting shaft 3 is slidably connected in the shifting groove 201. The end of the adjusting shaft 3 is rotatably connected to a guide roller 4 for supporting the metal rod body 11.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-3 The rotating arm 2 is fixedly connected to a bracket 5 near the transfer groove 201. The bottom end of the bracket 5 is flush with the bottom end of the housing 1 and is used to contact the ground or table. The bracket 5 is fixedly connected to an inclined platform 6 for supporting the adjusting shaft 3. The bracket 5 can improve the stability of the guide roller 4, so that the guide roller 4 can better support the solid metal rod.

[0036] Specifically, the inclined platform 6 is provided with insertion holes 601 at intervals along the inclined plane direction. The inclined platform 6 is provided with a limiting block 7 for blocking the adjusting shaft 3. The bottom end of the limiting block 7 is fixedly connected with a plug 701 for inserting into the insertion hole 601. By adjusting the position of the limiting block 7 on the inclined platform 6, the height of the guide roller 4 axis can be adjusted.

[0037] Furthermore, a first limiting plate 301 and a second limiting plate 302 are fixedly connected to both sides of the shift groove 201 along the direction of the adjusting shaft 3. The diameters of the first limiting plate 301 and the second limiting plate 302 are both larger than the diameter of the adjusting shaft 3. The distance between the first limiting plate 301 and the second limiting plate 302 is equal to the thickness of the shift groove 201. The first limiting plate 301 and the second limiting plate 302 are used to restrict the movement of the adjusting shaft 3 along its own axis.

[0038] Second embodiment: A portable high-frequency induction heater, please refer to [link / reference]. Figure 1-6 Based on the first embodiment, the difference from the first embodiment is that both sides of the chassis 1 are provided with receiving grooves 101 for accommodating the first limiting plate 301, so that the rotating arm 2 can better fit the side of the chassis 1.

[0039] Furthermore, both sides of the chassis 1 are fixedly connected with stop plates 9 near the pivot of the rotating arm 2. When the two rotating arms 2 contact the stop plates 9, they are in the same straight line, allowing the rotating arms 2 to quickly unfold to maintain the same straight line position.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 2-6 The shift groove 201 is waist-shaped, allowing the adjusting shaft 3 to move and fit the top and bottom of the shift groove 201 respectively. The guide roller 4 has a tapered cross section, realizing automatic centering of the metal rod body 11.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-3 The adjusting shafts 3 on the same rotating arm 2 are all connected to each other through connecting rods 8, so that the height of multiple adjusting shafts 3 can be adjusted at the same time.

[0042] Specifically, the center of the guide roller 4 and the center of the coil 10 are in the same vertical plane, so that the metal rod body 11 supported by the guide roller 4 can pass through the center of the coil 10.

[0043] In practical operation, this utility model is as follows: The rotating arms 2 located on both sides of the chassis 1 are extended until the rotating arms 2 are in contact with the stop plate 9. The worker uses metal pliers to clamp the metal rod body 11 and pushes the metal rod body 11 from the guide roller 4 on one of the rotating arms 2 toward the coil 10. After passing through the coil 10, the metal rod body 11 will be supported by the guide roller 4 on the other rotating arm 2, thereby stabilizing the heating of the metal rod. When it is necessary to heat metal rods of different diameters, lift the connecting rod 8 and slide all the adjusting shafts 3 on the rotating arm 2 upward along the shift groove 201. After pulling out the limiting block 7, reinsert the limiting block 7 into the appropriate height insertion hole 601 on the inclined platform 6. Then lower the connecting rod 8 and restore the limiting block 7 to contact the corresponding adjusting shaft 3. The axis height of the guide roller 4 can be easily adjusted. When it is necessary to heat the metal short rod, rotate the retractable rotating arm 2 and return the rotating arm 2 to both sides of the casing 1, thereby avoiding affecting the rapid heating of the metal short rod.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
