[0002] With the rapid development of the electronics industry, electronic products are constantly moving towards miniaturization and precision, placing higher demands on soldering processes. In modern electronics manufacturing and related repair fields, soldering is a crucial basic process. As a key component of soldering irons or soldering stations, the soldering tip locking device ensures that the soldering tip accurately transfers heat during operation, providing a solid guarantee for high-quality soldering operations. This not only helps improve production efficiency and reduce product defect rates caused by soldering problems, but also helps technicians complete soldering tasks efficiently and accurately in scenarios such as electronic equipment repair.

[0003] Existing soldering irons use an elastic locking device to connect the soldering tip to the heating element. During long-term, high-intensity soldering operations, the elastic locking device can easily lose its elasticity due to vibrations and thermal expansion and contraction caused by temperature changes. This makes it impossible to reliably fix the soldering tip, causing it to shift during operation. This not only leads to deviations in the soldering position but also easily results in a large number of solder joints with poor soldering and other quality problems, affecting the performance and reliability of the product.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] This specific embodiment is a soldering iron tip locking device, the structural diagram of which is shown below. Figures 1-7As shown, the device includes a soldering iron handle 1, a heating element 2, and a soldering iron tip 3. The soldering iron handle 1 includes a handle part 4, a threaded connection part 5, a boss 6, and a fixing cylinder 7 connected in sequence. The heating element 2 is installed inside the fixing cylinder 7. The soldering iron tip 3 is sleeved on the right side of the fixing cylinder 7. A movable frame 8 is slidably sleeved on the outer surface of the boss 6. A through hole 9 is opened on the right side of the movable frame 8. Multiple slots 10 are opened on the inner wall of the through hole 9. Multiple locking blocks 11 are fixedly connected to the left side of the soldering iron tip 3. A locking cap 12 is threadedly connected to the threaded connection part 5. The locking cap 12 is used to fix the movable frame 8.

[0025] like Figure 1 , Figure 4 and Figure 6 As shown: In this embodiment, the soldering iron tip 3 includes a soldering head 301 and a mounting part 302. A stepped groove 303 is provided on the left side of the mounting part 302, and a mounting groove 304 corresponding to the heating element 2 is provided at the stepped groove 303. After locking the locking block 11 on the left side of the soldering iron tip 3, the fixing cylinder 7 contacts the stepped groove 303 on the soldering iron tip 3, and the heating element 2 is located in the mounting groove 304. The heating element 2 can effectively transfer heat to the soldering head 301.

[0026] like Figure 3 and Figure 5 As shown: In this embodiment, the welding head 301, the mounting part 302 and the multiple locking blocks 11 are integrally formed; this prevents the welding head 301 from loosening and better locks and fixes the soldering iron tip 3.

[0027] like Figure 1 and Figure 2 As shown: In this embodiment, the movable frame 8 includes a first fixing ring 801 and a second fixing ring 802. A through hole 9 is formed on the second fixing ring 802. A plurality of sliders 803 are fixedly connected between the first fixing ring 801 and the second fixing ring 802. The outer surface of the boss 6 is provided with a groove 804 corresponding to the slider 803. The first fixing ring 801 protrudes from the outer surface of the slider 803. In use, the movable frame 8 is sleeved on the outer surface of the boss 6. At this time, the slider 803 slides along the groove 804 on the boss 6, and the first fixing ring 801 can drive the slider 803 and the second fixing ring 802 to move to the left.

[0028] like Figure 1 and Figure 2 As shown: In this embodiment, the left side of the locking cap 12 is provided with a threaded groove and an annular portion 1201 corresponding to the first fixing ring 801 is formed; in this way, during the rotation of the locking cap 12, the annular portion 1201 can drive the protruding first fixing ring 801 to move to the left, thereby locking the locking block 11 on the left side of the soldering iron tip 3.

[0029] like Figure 2 and Figure 3As shown: In this embodiment, a heat insulation layer is fixedly connected to the outer surface of the locking cap 12, and an anti-slip texture 1202 is provided on the outer surface of the heat insulation layer; this allows the locking cap 12 to rotate better, and the anti-slip texture 1202 increases the friction during rotation to prevent burns.

[0030] like Figure 4 and Figure 5 As shown: In this embodiment, the slot 10 is larger than the size of the block 11, and multiple blocks 11 are circumferentially distributed on the outer left side of the soldering iron tip 3; in this way, when locking the blocks 11 on the left side of the soldering iron tip 3, the force is more even, and the soldering iron tip 3 is prevented from becoming loose during use.

[0031] like Figure 2 and Figure 7 As shown: In this embodiment, the diameter of the boss 6 is smaller than that of the threaded connection part 5, and the diameter of the fixing cylinder 7 is smaller than that of the boss 6; in this way, the movable frame 8 can be slidably fitted onto the outer surface of the boss 6, and the locking cap 12 is threadedly connected to the threaded connection part 5.

[0032] Working principle: The soldering iron tip 3 is divided into a soldering head 301 and a mounting part 302. During use, the locking cap 12 is loosened, and the movable frame 8 is moved to the right. Then, the mounting part 302 of the soldering iron tip 3 is fitted onto the outer surface of the fixed cylinder 7, allowing the left-side locking block 11 to insert into the slot 10. The soldering iron tip 3 is then rotated to move the locking block 11 away from the slot 10. The locking cap 12 is then rotated. Since the locking cap 12 is threadedly connected to the threaded connection part 5, during rotation, the locking cap 12 can drive the protruding first fixing ring 801 to move to the left via the annular part 1201. Due to the sliding... Block 803 slides along the groove 804 on the boss 6. At this time, the first fixing ring 801 drives the slider 803 and the second fixing ring 802 to move to the left. During the movement, the second fixing ring 802 can lock the locking block 11 on the left side of the soldering iron tip 3. At this time, the fixing cylinder 7 contacts the stepped groove 303 on the soldering iron tip 3, and the heating core 2 is located in the mounting groove 304, so it is fixed by threaded connection. The locking cap 12 is away from the heating core 2 to prevent the soldering iron tip 3 from loosening during use. When the soldering iron handle 1 is not replaced, there is no need to remove the locking cap 12, making replacement more convenient.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] 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.
