Description

Technical Field

[0001] This utility model relates to the field of induction heating machine technology, and in particular to a portable induction heating machine. Background Technology

[0002] An induction heating machine is a device that uses the principle of electromagnetic induction to heat metal materials. Its working principle involves generating an alternating magnetic field in an induction coil using an alternating current. When the metal material is placed in this magnetic field, eddy currents are generated inside the material. As these eddy currents flow within the metal, they generate heat due to resistance, thus achieving the heating effect. For use in confined environments, a smaller and more portable induction heating machine is needed.

[0003] The existing portable induction heating device is a small main unit with an input wire connected to one end for easy power connection, and a groove for inserting the heating head at the other end. The heating head is inserted into the groove and secured with bolts on both sides of the main unit. After connecting to the power supply, it can be used directly.

[0004] Although this induction heater is portable, the main unit is not light and requires considerable arm strength to lift. It must not shake when heating the pipe. However, due to the heavy weight of the main unit, it is inevitable that it will shake after prolonged use. The heating head hitting the heated part of the pipe can easily cause the pipe to deform. Therefore, this application proposes a portable induction heater. Utility Model Content

[0005] The purpose of this invention is to address the problems in the background technology where the main unit is not light and requires considerable arm strength to lift during use, and cannot shake when heating the pipe. However, the main unit is heavy and inevitably shakes after prolonged use. Furthermore, the heating head hitting the heated part of the pipe can easily cause deformation of the pipe. Therefore, this invention proposes a portable induction heating machine.

[0006] The technical solution of this utility model is as follows: A portable induction heater includes a heater body, a heating coil is embedded inside the heater body near one end, a start / stop button is provided on the outside of the heater body, a positioning sleeve is embedded on the outside of the heater body, a positioning frame is fixedly connected to the outside of the positioning sleeve, the positioning frame is arranged in an "L" shape, a worm spring is provided on one side of the positioning frame, the end of the worm spring near the center is fixedly connected to the positioning frame, a gear is fixedly connected to the end of the worm spring away from the center, a rack is meshed with the gear, and a clamping component is provided at one end of the rack.

[0007] Optionally, the clamping assembly includes two clamping plates arranged symmetrically. A spring sheet is fixedly connected to one side of the clamping plate away from the rack. The spring sheet has an arc-shaped structure.

[0008] Optionally, there are two racks arranged symmetrically in an upper and lower configuration, and another set of clamps is fixedly connected to one end of the other rack. A limit component is provided on the outside of the rack.

[0009] Optionally, the limiting component includes a slide rail, which is slidably connected to the rack on the side away from the gear, and fixedly connected to the positioning frame on one side, and the slide rail is arranged in an "L" shape.

[0010] Optionally, the end of the spring piece away from the rack is fixedly connected to the clamping plate, the other end of the spring piece is slidably connected to the clamping plate, and the end of the positioning frame away from the positioning sleeve is fixedly connected to a pressing plate.

[0011] Optionally, the heating machine body has two bolts internally threaded and arranged symmetrically, with one end of each bolt abutting against the outside of the heating coil.

[0012] Optionally, an electric wire is fixedly connected to the end of the heating machine body away from the heating coil, and a three-phase plug is fixedly connected to the end of the electric wire away from the heating machine body.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 , Figure 3 and Figure 6 As shown, this utility model proposes a portable induction heater, including a heater body 1. A heating coil 17 is fitted inside the heater body 1 near one end. A start / stop button 16 is provided on the outside of the heater body 1. A positioning sleeve 2 is fitted outside the heater body 1, and a positioning frame 3 is fixedly connected to the outside of the positioning sleeve 2. The positioning frame 3 is L-shaped, and a worm spring 13 is provided on one side of the positioning frame 3. The end of the worm spring 13 near the center is fixedly connected to the positioning frame 3, and a gear 4 is fixedly connected to the end of the worm spring 13 away from the center. By connecting the worm spring 13 to the different ends of the positioning frame 3 and the gear 4, the gear 4 can spring back to its original position. A rack 5 is meshed with the outside of the wheel 4. A clamping component is provided at one end of the rack 5. There are two racks 5 arranged symmetrically up and down. Another set of clamping plates 7 is fixedly connected to one end of the other rack 5. A limit component is provided on the outside of the rack 5, so that the springback of the gear 4 drives the rack 5 to move in opposite directions, thereby allowing the rack 5 to drive the clamping plate 7 to close and clamp. Bolts 12 are threaded inside the heating machine body 1. There are two bolts 12 arranged symmetrically. One end of the bolt 12 abuts against the outside of the heating coil 17. A wire 14 is fixedly connected to the end of the heating machine body 1 away from the heating coil 17. A three-phase plug 15 is fixedly connected to the end of the wire 14 away from the heating machine body 1.

[0024] Figure 1 , Figure 2 and Figure 5As shown, the clamping assembly includes clamping plates 7, two of which are symmetrically arranged. A spring sheet 9 is fixedly connected to one side of the clamping plates 7 away from the rack 5. The spring sheet 9 has an arc-shaped structure, and its elastic material allows the material to be heated to enter between the clamping plates 7 more easily during auxiliary support. The limiting assembly includes a slide rail 8, which is slidably connected to the rack 5 on the side away from the gear 4 and fixedly connected to the positioning frame 3 on the side. The slide rail 8 is L-shaped, allowing the rack 5 to slide more smoothly and steadily. One end of the spring sheet 9 away from the rack 5 is fixedly connected to the clamping plate 7, and the other end is slidably connected to the clamping plate 7. This fixed-end and unfixed-end configuration allows for better compression and rebound of the spring sheet 9. A compression plate 10 is fixedly connected to the end of the positioning frame 3 away from the positioning sleeve 2. The two spring sheets 9 and the compression plate 10 form a three-point support effect, allowing for lifting with less force when using the heating machine body 1.

[0025] like Figure 2 and Figure 4 As shown, based on embodiment 1, a fitting groove 11 is provided on one side of the positioning sleeve 2. There are two sets of fitting grooves 11 symmetrically provided on one side of the positioning sleeve 2. The interior of the fitting groove 11 is slidably connected to the exterior of the bolt 12. The fitting groove 11 and the bolt 12 are fitted and slidably connected to each other, which can play an auxiliary connection role for the positioning sleeve 2 and ensure that the positioning sleeve 2 will not fall off. The side of the fitting groove 11 near the positioning sleeve 2 is rounded. The rounded corner structure of the fitting groove 11 ensures the accuracy of the fitting groove 11 being pushed into the exterior of the bolt 12.

[0026] In this embodiment, during use, the positioning sleeve 2 is first clipped onto the outside of the heating machine body 1 along one side. Then, the positioning sleeve 2 is slid so that it is embedded in the outside of the bolt 12 by the fitting groove 11. The heating coil 17 is then inserted into one end of the heating machine body 1, and the bolt 12 is rotated and tightened. In this way, the bolt 12 can fix both the heating coil 17 and the positioning sleeve 2. At this point, the three-phase plug 15 can be connected to the power supply, and electrical energy enters the heating machine body 1 along the wire 14. The start / stop button 16 can be activated to heat the heating coil 17.

[0027] When in use, the end of the pipe that needs to be heated can be pushed in between the spring pieces 9. The spring pieces 9 will be squeezed and deformed first. When the pipe is thick, the clamp 7 will be driven to open. When the clamp 7 is opened, it will drive the two racks 5 to move away from each other. When the pipe enters between the clamps 7, the spring pieces 9 will push the pipe to touch the extrusion plate 10.

[0028] The worm spring 13 also drives the gear 4 to reset, which in turn drives the rack 5 to move. The rack 5 is limited by the slide rail 8 when sliding to prevent it from deviating or tilting. When the rack 5 moves, it drives the clamping plate 7 to apply pressure to the outer wall of the pipe. The other side of the pipe is pressed against the side of the extrusion plate 10 by the spring 9, thus forming a three-point support effect. The pipe is inserted between the heating coils 17 for heating. The three-point clamping of the spring 9 and the extrusion plate 10 reduces the weight during operation.

[0029] The smooth structure of the spring 9 and the extrusion plate 10 when moving downwards ensures that the heating machine body 1 can move up and down. After heating is completed, the heating machine body 1 can be pulled directly to make the pipe extrude the spring 9 and remove the pipe from between the clamping plates 7. This allows the bolt 12 to be slightly loosened and the positioning sleeve 2 to be pushed backward. The bolt 12 is disengaged from the inside of the fitting groove 11, and the positioning sleeve 2 can be removed from the outside of the heating machine body 1.

[0030] It should be noted that this device uses a positioning sleeve 2 to fix the positioning sleeve 2 outside the bolt 12, and then uses the worm spring 13 to drive the gear 4 to rotate to control the rack 5 to extend and return to its original position. This allows the clamping plate 7 and the spring 9 to cooperate with the pressing plate 10 to provide three-point support, which reduces the problem of the control equipment shaking when heating the outside of a long pipe and improves the stability when heating the pipe.

[0031] 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.
