Description

Technical Field

[0001] The utility model relates to the technical field of soldering equipment, in particular to an electric soldering iron. Background Art

[0002] Soldering is a process that uses high-temperature heating to melt tin wire, and then uses the melting and solidification of the tin wire to weld products. In existing soldering operations, an electric soldering iron is usually used to heat the tin wire.

[0003] When using a soldering iron, it is often necessary to use it with a soldering iron stand. After the soldering work is completed, the soldering iron is placed on the soldering iron stand. Since the soldering iron and the soldering iron stand are mostly separate, the soldering iron is often placed flat on the table directly after being used alone. However, after the soldering iron is used, the temperature of the soldering iron tip cannot be quickly lowered in a short period of time. Placing it flat is dangerous and may cause scalding or burn other items. The separate soldering iron stand and soldering iron are very inconvenient to use.

[0004] In addition, in the existing soldering operation, the workers usually need to use both hands to operate when performing soldering. One hand is needed to hold the soldering iron for soldering, and the other hand is needed to feed the tin wire. This is inconvenient to operate and is not conducive to freeing both hands. In addition, feeding the wire by holding it manually can easily cause the tin wire to shake during feeding, affecting the stability of the welding process. At present, some soldering irons that can be operated with one hand on the market have tin inlet adjustment points that are mostly located near the wiring terminals of the soldering iron, and they need to be adjusted separately when tin is needed. When working, the soldering workers usually hold the middle or front part of the soldering iron with their hands, similar to holding a pen. To adjust the tin inlet point separately, they need to free up their hands to turn the adjustment knob, and then come back to hold the soldering iron. This is more troublesome to operate and not very convenient to use, and at the same time causes low soldering efficiency.

[0005] Therefore, we design an electric soldering iron to provide another technical solution to the above technical problem. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] Embodiment 1

[0026] Reference Figure 1-4 , an electric soldering iron, comprising a main shell 1, a soldering iron tip 3 and a connecting shell 4, wherein the connecting shell 4 is fixedly connected to one end of the soldering iron tip 3, and the soldering iron tip 3 is connected to the end of the connecting shell 4 away from the main shell 1, and a supporting mechanism is arranged on the outer side of the main shell 1 close to the end of the connecting shell 4, and a tin inlet part is arranged on one side of the main shell 1, and the tin inlet part comprises a driven adjustment gear 10, a mounting cylinder 11 and a tin inlet shell 12. By directly installing the supporting mechanism on the main shell 1, the supporting part and the electric soldering iron are integrated into one design. After use, the electric soldering iron can be directly placed on a desktop or other platform and supported by the supporting legs 8, which is convenient to operate, improves the convenience during use, and reduces the high temperature risk of the soldering iron tip; through the arrangement of the tin inlet part, the electric soldering iron can be operated with one hand during use, which improves the efficiency of soldering and increases the convenience during use.

[0027] Reference Figure 4The support mechanism includes a support sleeve 2, which is sleeved on one end of the main housing 1 close to the connecting housing 4 and fixedly connected to the main housing 1. A placement groove 24 is provided on both sides of the bottom of the support sleeve 2. A connecting rod 28 is fixed to the inner side of the placement groove 24 close to the end of the connecting housing 4. A support leg 8 is rotatably connected to the outer side of the connecting rod 28. A torsion spring 23 is provided between the support leg 8 and the placement groove 24 and on the outer side of the connecting rod 28. A limiting protrusion 22 is provided on both sides of the support leg 8 away from the end of the support sleeve 2. A groove that matches the limiting protrusion 22 is opened on the inner side of the placement groove 24. Specifically, when the main shell 1 needs to be supported, the support leg 8 is pushed out from the inner side of the placement groove 24, so that the card slot 26 can pop out under the action of the torsion spring 23, and then the soldering iron can be placed on the workbench. When soldering work is required, the card slot 26 can be pressed into the inner side of the placement groove 24. It should be noted that the placement groove 24 plays a certain limiting role on the support leg 8 through the cooperation of the groove and the limiting protrusion 22.

[0028] Embodiment 2

[0029] In the first embodiment, the support mechanism limits the support leg 8 only by the cooperation between the groove on the inner side of the placement slot 24 and the limiting protrusion 22. After long-term use, the limiting effect of the groove on the limiting protrusion 22 may be reduced, so that the placement slot 24 cannot limit the support leg 8 well, which may cause the support leg 8 to often pop out when no supporting work is needed, causing certain inconveniences in the soldering work. Therefore, this embodiment further optimizes the first embodiment.

[0030] Reference Figure 2 and Figure 4 An adjusting ring 7 is slidably connected to the outer side of the main housing 1 and located at one end of the supporting sleeve 2. An anti-slip pad 13 is provided on the top of the adjusting ring 7. A spring 27 is provided on the inner side of the adjusting ring 7. The spring 27 is sleeved on the outer side of the main housing 1. The two ends of the spring 27 are respectively connected to the adjusting ring 7 and the spring 27. A card slot 26 is provided at the bottom of the supporting leg 8 near one end of the supporting sleeve 2. A card block 25 matching the card slot 26 is fixedly connected to one end of the adjusting ring 7 near the supporting leg 8. Specifically, the adjusting ring 7 is sleeved on the outer side of the main housing 1 and slidably connected to the main housing 1. The adjusting ring 7 cooperates with the card block 25 and the card slot 26 To limit the support leg 8, when in use, in a natural state, the adjusting ring 7 is against the support sleeve 2 under the action of the spring 27. When no supporting work is needed, the anti-slip pad 13 can be pressed with a finger to move the adjusting ring 7, and then the support leg 8 is pressed into the inner side of the placement groove 24, and then the adjusting ring 7 is released, so that the adjusting ring 7 is against the support sleeve 2 under the action of the spring 27. At this time, the block 25 is inserted into the inner side of the slot 26, so as to limit the support leg 8. When supporting work is needed, the adjusting ring 7 is moved to make the block 25 detach from the inner side of the slot 26, and the support leg 8 pops out under the action of the torsion spring 23.

[0031] This embodiment limits the support leg 8 by cooperating with the adjustment ring 7 and the support leg 8, which can prevent the support leg 8 from accidentally popping out, and the limiting of the support leg 8 is relatively stable. At the same time, the operation of storing and releasing the support leg 8 is relatively simple, which greatly improves the convenience during use.

At this time, the thumb or other fingers of the person are near the active adjusting gear 6 or placed on the active adjusting gear 6. When the tinning operation is required, the active adjusting gear 6 only needs to be moved by the finger to rotate, which can drive the driven adjusting gear 10 and then perform the tinning operation. The whole process is simple to operate and does not require a large range of hand movement, which improves the comfort and convenience of use.

[0035] Reference Figure 1-3 , one end of the driven adjustment gear 10 is fixedly connected to a first bevel gear 14 located on the inner side of the mounting tube 11, one end of the first bevel gear 14 away from the driven adjustment gear 10 is meshedly connected to a second bevel gear 15, the second bevel gear 15 is rotatably connected to the mounting tube 11, a first transmission gear 16 is fixedly connected to the bottom of the second bevel gear 15, one end of the first transmission gear 16 is meshedly connected to a second transmission gear 17, a first tin-feeding wheel 18 is fixedly connected to the inner side of the second transmission gear 17, the first tin-feeding wheel 18 is rotatably connected to the mounting tube 11, the mounting tube 11 and a second tin feeding wheel 19 is provided on the inner side and on one side of the first tin feeding wheel 18, and the tin wire 9 is located between the first tin feeding wheel 18 and the second tin feeding wheel 19. Specifically, when the driven adjusting gear 10 rotates, it will drive the first bevel gear 14 to rotate, and then drive the second bevel gear 15, the first transmission gear 16, the second transmission gear 17 and the first tin feeding wheel 18 to rotate in sequence. When in use, the second transmission gear 17 and the second tin feeding wheel 19 will press the tin wire 9, and when the first tin feeding wheel 18 rotates, it can drive the tin wire 9 to move forward, thereby achieving the effect of tin feeding.

[0036] Reference Figure 3The inner side of the mounting tube 11 near the second tin feeding wheel 19 is threadedly connected with an adjusting rod 21, one end of the adjusting rod 21 is rotatably connected with a support frame 20 located on the inner side of the mounting tube 11, and the second tin feeding wheel 19 is rotatably connected to the inner side of the support frame 20. Specifically, by rotating the adjusting rod 21, the support frame 20 can be driven to perform displacement movement, thereby adjusting the distance between the second tin feeding wheel 19 and the first tin feeding wheel 18 to adapt to the feeding of tin wires 9 of different diameters, thereby improving the adaptability of the electric soldering iron when used.

[0037] Reference Figure 2 A connecting block 5 is fixed to the outer side of the tin inlet shell 12 near one end of the main shell 1, and the connecting block 5 is sleeved on the outer side of the main shell 1. A positioning screw 29 is threadedly connected to the inner side of the connecting block 5 and located on the outer side of the main shell 1. The positioning screw 29 abuts against the main shell 1. Specifically, the connecting block 5 can be rotatably connected to the main shell 1, and the positioning screw 29 is used to limit the position of the connecting block 5, so that the position of the connecting block 5 relative to the main shell 1 can be adjusted, thereby adjusting the position of the tin inlet part relative to the main shell 1 according to the usage needs of different people, improving the user experience and comfort, and at the same time improving the adaptability of use. At the same time, the tin inlet part can be removed by removing the positioning screw 29, which improves the convenience of maintenance.

[0038] The use process of an electric soldering iron provided by the utility model is as follows:

[0039] When there is no need to perform supporting work, the anti-slip pad 13 can be pressed with a finger to move the adjusting ring 7, and then the supporting leg 8 can be pressed into the inner side of the placement groove 24, and then the adjusting ring 7 can be released, so that the adjusting ring 7 can be pressed against the supporting sleeve 2 under the action of the spring 27, and the clamping block 25 can be inserted into the inner side of the clamping groove 26 to limit the supporting leg 8. When supporting work is required, the adjusting ring 7 can be moved to make the clamping block 25 disengage from the inner side of the clamping groove 26, and the supporting leg 8 can be popped out under the action of the torsion spring 23;

[0040] When tinning is needed, one only needs to use one's finger to move the active adjusting gear 6 to make it rotate, thereby driving the driven adjusting gear 10. When the driven adjusting gear 10 rotates, it will drive the first bevel gear 14 to rotate, and then drive the second bevel gear 15, the first transmission gear 16, the second transmission gear 17 and the first tin-feeding wheel 18 to rotate in sequence. When in use, the second transmission gear 17 and the second tin-feeding wheel 19 will press the tin wire 9.
