[0002] Soldering irons are essential tools for electronics manufacturing and electrical appliance repair. Their main purpose is to solder components and wires. According to their mechanical structure, they can be divided into internal heating soldering irons and external heating soldering irons. According to their function, they can be divided into non-desoldering soldering irons and desoldering soldering irons. According to their different uses, they can also be divided into high-power soldering irons and low-power soldering irons.

[0003] To make it easier for staff to operate, soldering irons have gradually evolved into a gun-shaped handheld structure. When using them, the soldering iron is held in a gun-like manner, which makes it easier for the operator to align the solder joint and apply force.

[0004] However, due to the special structure of soldering irons, the power receiving part is usually located in the grip area, while the heating element is located in the soldering iron core. Therefore, in order to ensure the power connection stability of the soldering iron core, existing soldering irons fix the soldering iron core and the grip area together. This makes the entire soldering iron quite long, which is inconvenient for workers to carry. Utility Model Content

[0037] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the following will be combined with the drawings and the preferred embodiments to specifically describe the specific embodiments, structures, features and effects of the utility model.

[0038] Specifically referring to Figures 1-6 As shown in the figure, the following embodiments disclose a gun type electric soldering iron.

[0039] Embodiment 1

[0040] A gun type electric soldering iron, comprising:

[0041] The gun type handle 100 is provided with a switch 1 for controlling the on-off of the control circuit and a gear key 2 for controlling the temperature.

[0042] A soldering iron core 200 is arranged at the front end of the gun handle 100.

[0043] The tail end of the soldering iron core 200 is arranged as a fitting end 210, and the front end of the gun handle 100 is arranged as a mounting end 110. A quick mounting structure is arranged between the fitting end 210 and the mounting end 110, which mounts the soldering iron core 200 to the gun handle 100 and communicates with the circuit in the gun handle 100.

[0044] The above is the basic scheme of the embodiment.

[0045] With reference to Figure 1 As shown, the soldering iron core 200 includes a soldering iron head at the front end and a heat insulation pipe, and a core body arranged in the heat insulation pipe for heating. The core body is powered to generate heat, so that the soldering iron head is high-temperature, and the soldering iron head melts the solder and welds the components.

[0046] The gun handle 100 has at least a circuit board inside, and the on-off of the circuit is controlled by a switch 1 and a gear key 2, and the heating gear is selected.

[0047] The circuit control of the soldering iron core 200 by the circuit board is a prior art, which will not be described here.

[0048] With reference to Figure 2 As shown, in the embodiment, the soldering iron core 200 can be detached from the gun handle 100 for separate storage in the storage state. In this way, the length of the soldering iron as a whole is reduced, and the gun handle 100 and the soldering iron core 200 can be stored and carried together in a smaller equipment space.

[0049] When needed, the soldering iron core 200 is mounted to the front end of the gun handle 100, that is, the fitting end 210 and the mounting end 110 are fitted, so that the soldering iron core 200 can communicate with the circuit in the gun handle 100. At this time, the circuit is turned on and can be used.

[0050] In the embodiment, an external power cord can be arranged on the gun handle 100 to take power from external mains, or a battery can be loaded in the gun handle 100 for power supply. Both of the two power supply modes are commonly used in the prior art, which will not be described here.

[0051] Specifically, when the soldering iron core 200 is installed on the gun handle 100, in addition to the need to fix the soldering iron core 200 and the gun handle 100, the circuit connection between the soldering iron core 200 and the gun handle 100 is also needed. In the embodiment, the quick installation structure includes an adsorption assembly and a conductive assembly arranged between the mounting end 110 and the assembly end 210. The adsorption assembly adsorbs and tightly attaches the soldering iron core 200 and the gun handle 100, so that the conductive assembly is in contact and powered on.

[0052] The adsorption assembly can tightly attach the assembly end 210 to the mounting end 110. When the end faces of the assembly end 210 and the mounting end 110 are tightly attached, the conductive assembly is in contact and conduction. At this time, the switch 1 on the gun handle 100 is opened, the circuit is connected, and the core body in the soldering iron core 200 can be powered and heated.

[0053] Specifically, the conductive assembly includes a conductive terminal 310 arranged in the mounting end 110 and capable of being exposed to the outside of the mounting end 110. The assembly end 210 is provided with a conductive groove 320 capable of accommodating the insertion of the conductive terminal 310.

[0054] Specifically referring to Figure 3 and Figure 4 In the embodiment, the conductive terminal 310 is a conventional conductive terminal 310 made of metal and penetrating the mounting end 110. The outer end can be exposed to the outside of the mounting end 110, and the inner end is connected with the circuit board wire in the gun handle 100. At the same time, the conductive groove 320 is provided with a metal conductive sheet capable of contacting the conductive terminal 310. The conductive sheet is arranged at least on the groove bottom of the conductive groove 320 and is electrically connected to the core body of the soldering iron core 200. The conductive terminal 310 is inserted into the conductive groove 320 and contacts the metal conductive sheet, so that the circuit can be conducted.

[0055] Preferably, the end of the conductive terminal 310 is arranged in a circular arc type, and the conductive groove 320 is embedded on the end face of the assembly end 210.

[0056] In the embodiment, the quick installation structure includes a magnetic adsorption piece 410 and a metal piece 420 arranged between the assembly end 210 and the mounting end 110. The assembly end 210 of the soldering iron core 200 is attached to the mounting end 110 of the gun handle 100, and the magnetic adsorption piece 410 and the metal piece 420 are adsorbed to fix the soldering iron core 200 and the front end of the gun handle 100.

[0057] Preferably, in the embodiment, the magnetic adsorption piece 410 is embedded on the end face of the mounting end 110, the metal piece 420 is embedded on the end face of the assembly end 210, and the positions and structures of the magnetic adsorption piece 410 and the metal piece 420 are correspondingly arranged.

[0058] Based on the above setting, the positioning can be ensured when the soldering iron core 200 is installed on the gun handle 100, because the magnetic attraction piece 410 and the metal piece 420 need to be attracted correspondingly, so that the conductive assembly can be connected correspondingly.

[0059] In other embodiments, two magnetic attraction pieces 410 that are different in magnetism can also be provided.

[0060] Based on the above setting, the magnetic attraction piece 410 is arranged on the mounting end 110, so that different models of soldering iron cores 200 can be assembled on the gun handle 100, increasing the adaptability.

[0061] In the embodiment, to avoid the soldering iron core 200 from being detached from the gun handle 100 due to unstable magnetic attraction during use, a limiting sleeve 500 is further included, which is a cover body, and the cover body 520 is provided with a through hole 521.

[0062] The limiting sleeve 500 is threadedly connected to the gun handle 100.

[0063] Specifically referring to Figure 5 As shown in the figure, the limiting sleeve 500 includes a sleeve part 510 provided with threads at the inner circle, and a cover part 520 arranged at one end of the sleeve part 510, and the limiting ring is used for limiting the end part of the soldering iron core 200.

[0064] The assembly end 210 of the soldering iron core 200 is provided with a shoulder, the outer diameter of the shoulder 220 is greater than the hole diameter of the through hole 521 of the limiting sleeve 500, and the hole diameter of the through hole 521 is greater than the diameter of the soldering iron core 200. When the soldering iron core 200 is connected to the gun handle 100 by magnetic attraction, the limiting sleeve 500 is sleeved on the head of the soldering iron core 200, pushed to the position where the assembly end 210 is connected to the gun handle 100, and threadedly connected to the gun handle 100, so as to ensure the firm connection of the soldering iron core 200 and the gun handle 100.

[0065] The mounting end 110 of the gun handle 100 is provided with external threads matched with the limiting sleeve 500.

[0066] Embodiment 2

[0067] The embodiment is an improvement based on the embodiment 1, and the purpose is to provide another limiting method to make the connection of the soldering iron core 200 and the gun handle 100 more firm; the specific implementation is:

[0068] The assembly end 210 and the mounting end 110 are limited by rotation, and the mounting end 110 and the assembly end 210 are further provided with a limiting structure, which includes a limiting groove 111.1 arranged on the mounting end 110, and a sliding block 221 arranged on the soldering iron core 200 and matched with the locking arm.

[0069] With reference to Figure 4 and Figure 5 As shown in the figure, when the soldering iron core 200 is mounted on the gun handle 100, the assembly end 210 of the soldering iron core 200 is in close contact with the mounting end 110 of the gun handle 100, and the sliding block 221 is aligned with the limiting groove 111.1. The soldering iron core 200 is rotated so that the assembly end 210 is in close contact with the mounting end 110 and rotates the sliding block 221 to slide into the limiting groove 111.1. When the sliding block 221 is completely slid into the limiting groove 111.1, the adsorption assembly is aligned in the locking position and can be adsorbed.

[0070] With reference to Figure 3 and Figure 4 As shown in the figure, the outer edge of the mounting end 110 is provided with an L-shaped limiting block 111, and the limiting block 111 and the end face of the mounting end 110 form a limiting groove 111.1. The shoulder of the assembly end 210 is provided with an arc-shaped sliding block 221.

[0071] In this embodiment, the limiting block 111 is provided with a plurality of limiting blocks 111, and the adjacent limiting blocks 111 form a gap capable of accommodating the sliding block 221.

[0072] In order to increase the applicability of the conductive assembly and avoid wear of the conductive terminal 310 during rotation of the soldering iron core 200, in this embodiment, the conductive terminal 310 is movably arranged in the axial direction of the mounting end 110 and can be retracted into the inside of the mounting end 110 under the driving of an external force, so as to be separated from the conductive groove 320.

[0073] When the soldering iron core 200 is assembled, the conductive terminal 310 is first pushed by an external force and retracted into the inside of the gun handle 100, so that at least the end portion is flush with the end face of the mounting end 110. At this time, the assembly end 210 of the soldering iron core 200 is positioned and coincided with the mounting end 110 of the gun handle 100, and the soldering iron core 200 is rotated relative to the gun handle 100, and rotated to the locking position. At this time, the adsorption assembly is adsorbed, so that the soldering iron core 200 is fixed to the gun handle 100, and at the same time, the sliding block 221 is limited in the limiting groove 111.1.

[0074] Based on the above arrangement, since the conductive terminal 310 is retracted into the inside of the gun handle 100 during assembly, that is, the mounting end 110 is a flat surface, and when the assembly end 210 is rotated relative to the mounting end 110, it does not contact the conductive terminal 310, so as not to cause adverse contact such as wear of the conductive terminal 310, thereby ensuring the integrity of the conductive terminal 310.

[0075] Specifically, the inside of the gun handle 100 is provided with a moving block 120 inside the mounting end 110, the side of the moving block 120 is provided with a knob 130, and the gun handle 100 is provided with a slot corresponding to the knob 130 and capable of accommodating the movement of the knob 130.

[0076] The conductive terminal 310 is arranged on the first end face of the moving block 120.

[0077] The front end of the conductive terminal 310 is exposed to the outside of the moving block 120, and the rear end is connected with the wire on the other side of the moving block 120. When the moving block 120 moves along the slot under the action of the knob 130, the conductive terminal 310 also moves.

[0078] When the external force on the knob 130 is removed, the conductive terminal 310 can be automatically reset. In the embodiment, the second end face of the moving block 120 and the inner wall of the gun handle 100 are provided with an elastic supporting piece 3, which supports the moving block 120 outward to expose the conductive terminal 310 to the outside of the mounting end 110.

[0079] The inner wall of the gun handle 100 extends towards the center and is provided with an abutting plate 140 arranged in an annular structure, and the center hollow part cannot accommodate the elastic supporting piece 3 to pass through, and the hollow part is used for wiring;

[0080] The inner end of the elastic supporting piece 3 is supported on the abutting plate 140, and the outer end is abutted to the second end face of the sliding block 221, so that the sliding block 221 has a tendency to move outward.

[0081] After the soldering iron core 200 is rotated and positioned on the gun handle 100 or detached from the gun handle 100, the external force on the knob 130 is removed, the elastic supporting piece 3 is reset, the sliding block 221 is pushed out, and the conductive terminal 310 is stretched out to the outside of the mounting end 110. When the soldering iron core 200 is positioned on the gun handle 100, it can be stretched into the conductive groove 320 for electrical connection. For details, refer to Figure 6 .

[0082] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the technical solution of the present application, and any equivalent embodiments with equivalent changes and modifications are still within the scope of the present application.
