Technical Field

[0001] The present disclosure relates to the field of electric soldering irons, and in particular to an adjustable internally heated double-headed electric soldering iron. Background Art

[0002] A soldering iron is an essential tool for electronics manufacturing and appliance repair. Its primary purpose is soldering components and wires. Based on their mechanical structure, they can be categorized as internally heated and externally heated. An externally heated soldering iron consists of a tip, core, outer casing, wooden handle, power cord, and plug. Because the tip is mounted inside the core, it's called an externally heated soldering iron. An internally heated soldering iron consists of a handle, connecting rod, spring clip, core, and tip. Because the core is mounted inside the tip, it heats up quickly and utilizes heat efficiently, hence the name internally heated soldering iron.

[0003] Ordinary internal heating soldering irons can only heat one side of the pad and cannot heat both sides of the pad of packaged large inductor electronic components at the same time to improve removal efficiency. Summary of the Invention

[0008] In one embodiment, a support seat is rotatably provided on the top of the adjusting nut, and the outer support cylinder is provided on the support seat.

[0009] In one embodiment, an inner supporting tube is disposed in the outer supporting tube, the bottom of the inner supporting tube is threadedly connected to the bottom of the outer supporting tube, and the bottom gap of the mounting head is disposed in the inner supporting tube.

[0010] In one embodiment, an elastic clamp is provided on the top of the inner support tube, and the mounting head and the inner support tube abut against each other through the elastic clamp.

[0026] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0027] In order to achieve simultaneous heating of both sides of the soldering pad of a packaged large-inductance electronic component, the present disclosure provides an adjustable internally heated double-ended electric soldering iron.

[0028] Reference Figure 1-Figure 3In an embodiment of the present disclosure, an adjustable internal heating double-headed electric soldering iron includes: two soldering tips 1 that can be opened and closed, an outer support tube 2, and a driving mechanism for driving the soldering tips 1 to open, the soldering tip 1 includes a mounting head 11 and a welding tip 12, the mounting head 11 is arranged in the outer support tube 2, and the welding tip 12 extends out of the outer support tube 2, the driving mechanism includes a cone 31 and a traction portion 32, a cone cavity 13 is arranged between the two soldering tips 1, the cone 31 is arranged in the cone cavity 13 and is limited by the cone cavity 13, specifically, the cone 31 is arranged as a cone, and when the two soldering tips 1 are in a merged state, the cone surface of the cone 31 fits the side wall of the cone cavity 13. The bottom end of the cone 31 is connected to the pulling portion 32. The pulling portion 32 is moved downward by the driving mechanism, thereby pulling the cone 31 downward. After the cone 31 is pulled downward, the cone surface of the cone 31 always fits the side wall of the cone cavity 13. However, the further the cone 31 moves downward, the larger the diameter of its cross section becomes. The cone cavity 13 is squeezed, and the distance between the welding tips 12 of the two soldering iron tips 1 gradually increases, thereby realizing the operation of opening the soldering iron tips 1.

[0029] In the embodiment of the present disclosure, the outer support tube 2 is evenly cut along the circumference to form a plurality of elastic wedges. When the soldering iron tip 1 is opened, its outer contour abuts against the elastic wedges. Under the action of external tension, the outer support tube 2 expands outward to open a gap for the soldering iron tip 1 to flow out, and can also provide certain support to the outer contour of the soldering iron tip 1, so that the soldering tip 12 will not shake during use, thereby improving the accuracy of heating a specific position of the soldering pad.

[0030] Reference Figure 3-Figure 5 Specifically, the driving mechanism includes a traction power assembly 33, and the traction power assembly 33 includes an adjusting nut 331 and a lifting screw 332. The adjusting nut 331 and the lifting screw 332 are threaded together. Rotating the adjusting nut 331 can drive the lifting screw 332 to rise or fall relative to the adjusting nut 331. The lifting screw 332 is connected to the traction part 32. Then, after the lifting screw 332 descends, the traction part 32 descends, and the cone part 31 also descends, corresponding to the opening of the soldering iron tip 1; after the lifting screw 332 rises, the traction part 32 rises, and the cone part 31 also rises, corresponding to the merging or resetting of the soldering iron tip 1.

[0031] In an embodiment of the present disclosure, the adjustable internally heated double-headed soldering iron includes a handle 4, and an adjusting nut 331 is sleeved on the handle 4. The operator holds the handle 4 to operate the double-headed soldering iron of the present disclosure and can open or reset the soldering iron tip 1 by turning the adjusting nut 331 clockwise or counterclockwise.

[0032] In the embodiment of the present disclosure, the adjusting nut 331 and the handle 4 are both made of heat-insulating material.

[0033] Specifically, the handle 4 is cylindrical, and the adjustment nut 331 includes an outer ring 3311 and an inner ring 3312. The outer ring 3311 and the inner ring 3312 are coaxially arranged. The outer ring 3311 is arranged on the outside of the handle 4 and is coaxially connected to the handle 4. The inner ring 3312 is arranged on the inside of the handle 4. The outer ring 3311 and the inner ring 3312 are connected by a connecting rod 3313. The handle 4 is provided with an escape groove 41 to allow the connecting rod 3313 to pass through and rotate. The inner wall of the inner ring 3312 is provided with an internal thread that cooperates with the lifting screw 332. When the operator rotates the outer ring 3311 of the adjustment nut 331, the inner ring 3312 also rotates accordingly, thereby driving the lifting screw 332 to rotate relative to the thread of the inner ring 3312, thereby achieving the lifting and lowering adjustment of the lifting screw 332.

[0034] Reference Figure 3 and Figure 4 In the embodiment of the present disclosure, the top of the adjusting nut 331 is rotatably provided with a support seat 5, the outer support tube 2 is provided on the support seat 5, and the adjusting nut 331, the support seat 5 and the outer support tube 2 are coaxially provided.

[0035] In the embodiment of the present disclosure, an inner support tube 6 is disposed within the outer support tube 2. The inner support tube 6 is coaxial with the outer support tube 2. The bottom of the inner support tube 6 is threadedly connected to the bottom of the outer support tube 2. The bottom clearance of the mounting head 11 is set within the inner support tube 6. Specifically, an elastic clamp 7 is provided at the top of the inner support tube 6, and the mounting head 11 and the inner support tube 6 abut against each other through the elastic clamp 7.

[0036] Reference Figure 3-Figure 5 In the embodiment of the present disclosure, a soldering iron core 8 is embedded in the soldering iron tip 1, and a wire card 42 is provided in the handle 4. The soldering iron core 8 is connected to the wire card 42 through a connecting line 81. After the wire card 42 is plugged in, power is supplied to the soldering iron core 8, thereby heating the soldering iron tip 1 through the soldering iron core 8.

[0037] In the embodiment of the present disclosure, a fixing frame 61 is provided in the inner support tube 6, and a through hole is opened on the fixing frame 61 for accommodating the traction part 32 and the connecting line 81 to pass through. On the one hand, since the traction part 32 is relatively slender, it can play the role of limiting the traction part 32, so that the traction part 32 always maintains linear motion during the movement process; on the other hand, the fixing frame 61 can prevent the connecting line 81 from being entangled on the traction part 32.

[0038] It should be understood that the various forms of processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this disclosure can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions of this disclosure can be achieved, and this document is not limited here.

[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Directional terms such as "first direction" and "second direction" all refer to a certain linear direction, unless otherwise clearly and specifically defined. In the description of this disclosure, "plurality" means two or more, unless otherwise clearly and specifically defined.

[0040] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure.
