It is widely used in circuit assembly, electrical appliance repair, and industrial manufacturing. The soldering tip, a crucial component of the soldering iron, comes in various forms to adapt to different operational situations. The installation methods for the soldering tip are also diverse, including a screw-on installation method, where the tip connects to the soldering iron via a screw, facilitating disassembly and replacement with other types of soldering tips for greater convenience.

[0003] However, during use, soldering irons are inevitably subject to bumps, vibrations from the workbench in complex working environments, and pressure from objects. This can cause some of the spiral-mounted soldering iron tips to loosen after prolonged use, resulting in unstable operation. In addition, if the soldering iron tip is not replaced for a long time, it may become stuck, requiring the use of other tools for disassembly, making it inconvenient to use.

[0004] Therefore, a spiral-shaped, heatable soldering iron tip was designed to overcome the aforementioned technical shortcomings. Utility Model Content

[0028] This specific embodiment is a spiral-type heatable soldering iron tip, the structural diagram of which is shown below. Figures 1-8 As shown, the device includes a soldering iron body 1 and a soldering iron tip body 2. The soldering iron tip body 2 is mounted on the soldering iron body 1. A flange tube 3 is sleeved on the side wall of the soldering iron tip body 2. An external threaded tube 4 is sleeved on the side wall of the flange tube 3. An installation ring 5 is sleeved on the side wall of the flange tube 3. The installation ring 5 is fixedly connected to the external threaded tube 4. A clamping and fixing mechanism is provided between the installation ring 5 and the outer wall of the external threaded tube 4. A positioning mechanism is provided on the side wall of the flange tube 3. The positioning mechanism is fixedly connected to the installation ring 5.

[0029] The soldering iron body 1 in this technical solution is a common device on the market. It is a relatively mature technology and is common knowledge among people in this field. Therefore, its usage and the installation method of the soldering iron tip body 2 are not described in detail in this technical solution.

[0030] like Figures 3-8As shown, the clamping and fixing mechanism includes rectangular openings 6 evenly distributed on one side of the mounting ring 5. An arc-shaped clamping plate 7 is movably connected between the inner walls of the two sides of the rectangular opening 6. The left and right sides of the arc-shaped clamping plate 7 extend to the outside of the rectangular opening 6 respectively. The arc-shaped clamping plate 7 is arc-shaped. A conical ring 9 is fitted on the side wall of the external threaded pipe 4. The inclined surface of the conical ring 9 contacts the arc-shaped clamping plate 7. An internal threaded ring 10 is installed on the side wall of the external threaded pipe 4. The internal threaded ring 10 and the conical ring 9 are slidably connected.

[0031] By rotating the internal threaded ring 10, multiple arc-shaped clamps 7 can simultaneously clamp the soldering iron tip body 2. After clamping for a certain period of time, the arc-shaped clamps 7 will undergo slight deformation. At this point, the rotation of the internal threaded ring 10 can be stopped. Through clamping, the soldering iron tip body 2 will not become loose during use. In addition, due to the arc shape of the arc-shaped clamps 7, when the soldering iron body 1 is placed on the table, the soldering iron tip body 2 will not come into contact with the table, which can improve the safety of use.

[0032] like Figures 3-6 As shown, the positioning mechanism includes a hexagonal ring 12 sleeved on the side wall of the flange pipe 3. The hexagonal ring 12 is fixedly connected to the mounting ring 5. The outer wall of the hexagonal ring 12 is provided with evenly distributed threaded holes 13. A screw rod 14 is installed in the threaded holes 13. One end of the screw rod 14 extends into the hexagonal ring 12, and the other end extends to the outside of the hexagonal ring 12 and is fixedly connected to a knob 15.

[0033] When using it, you can choose how many lead screws 14 to use as needed. You can use one to six lead screws 14. The more lead screws 14 you use, the better the fixing effect. When disassembling the soldering iron tip body 2, you need to loosen the lead screws 14 so that you can rotate the mounting ring 5 and the arc-shaped clamp 7. The soldering iron tip body 2 will move after being screwed on, so the arc-shaped clamp 7 can move with the soldering iron tip body 2 and will not get stuck.

[0034] Among them, several curved clamps 7 are fixedly connected to anti-slip plates 8 on their left side walls. The anti-slip plates 8 are curved and contact the soldering iron tip body 2. The anti-slip plates 8 can increase the contact area between the curved clamps 7 and the soldering iron tip body 2, and prevent slippage when disassembling the soldering iron tip body 2.

[0035] In addition, a ring slider is fixedly connected to one side of the conical ring 9, and a ring groove matching the ring slider is opened on one side of the internal threaded ring 10. The cross-section of the ring slider is T-shaped. The ring slider and the ring groove enable the conical ring 9 to move without rotating when the internal threaded ring 10 rotates. This reduces friction with the arc-shaped clamp 7 and improves service life.

[0036] The inner threaded ring 10 has evenly distributed rotating handles 11 fixedly connected to its outer wall. The end of the rotating handle 11 that is far away from the inner threaded ring 10 is spherically shaped. Multiple rotating handles 11 can increase the convenience of use and save effort.

[0037] In addition, several knobs 15 are provided with screwdriver slots on the side away from the hexagonal ring 12. The screwdriver slots are arranged in a cross shape. This way, when the screw rod 14 cannot be turned manually, the screw rod 14 can be turned with the help of a screwdriver, which is beneficial for fixing the hexagonal ring 12.

[0038] Among them, several of the curved clamps 7 are made of stainless steel. Stainless steel is relatively stable in use and is not easily deformed when rotating the curved clamps 7. At the same time, stainless steel has the advantage of high temperature resistance, making it relatively safe to use.

[0039] Working Principle: In use, the soldering iron tip body 2 is first spirally mounted on the soldering iron body 1. Then, the external threaded tube 4 is slid to the far right position. Next, the screw 14 is tightened by the knob 15, causing it to press against the outer wall of the flange tube 3. This fixes the slid-out external threaded tube 4 and the mounting ring 5. Then, by turning the handle 11 clockwise, the internal threaded ring 10 pushes the conical ring 9 to the left. When the conical ring 9 moves to the left, the inclined surface of the conical ring 9 causes multiple arc-shaped clamps 7 to swing towards the center simultaneously and clamp the soldering iron tip body 2. Clamping the soldering iron tip body 2 secures it, effectively preventing it from loosening. When it is necessary to remove the soldering iron tip... When disassembling the soldering iron tip body 2, loosen the screw 14 again by turning the knob 15, so that the screw 14 is no longer in contact with the flange tube 3. Then, rotate the external threaded tube 4 and the mounting ring 5 together to drive the arc-shaped clamp 7 to rotate. Simultaneously, the arc-shaped clamp 7 rotates the soldering iron tip body 2, thus achieving the purpose of disassembling the soldering iron tip body 2. While loosening the soldering iron tip body 2, the soldering iron tip body 2 will gradually move to the left. The fixed clamping of the arc-shaped clamp 7 will drive the external threaded tube 4 to move to the left. This will not affect the normal disassembly of the soldering iron tip body 2. After the disassembly is completed, reverse the internal threaded ring 10. The internal threaded ring 10 will drive the conical ring 9 to move to the right. This will loosen the arc-shaped clamp 7. At this time, the soldering iron tip body 2 can be taken out, which can effectively improve the safety and convenience of use.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
