Description

Technical Field

[0001] This utility model relates to the field of soldering irons, and more specifically, to a foldable soldering iron structure. Background Technology

[0002] Soldering irons are essential tools for electronics manufacturing and appliance repair, and their main purpose is to solder components and wires. A search revealed an existing patent (publication number: CN222359410U) that discloses an electric soldering iron, comprising: a holdable pen body; a first soldering tip disposed at the lower end of the holdable pen body and arranged along the length direction of the holdable pen body; a second soldering tip disposed at the lower end of the holdable pen body and arranged along the length direction of the holdable pen body; and a moving component connected between the first soldering tip and the holdable pen body, for allowing the first soldering tip to move along the length direction of the holdable pen body and for allowing the first soldering tip to move laterally. This invention can improve the soldering efficiency of the electric soldering iron and the convenience of the soldering / desoldering process. At the same time, it can meet the soldering / desoldering habits of different users.

[0003] In the unfolding and fixing process, most existing soldering irons rely on a single snap-on fixing method. After long-term use, the snap-on is prone to wear, resulting in a decrease in fixing stability and failing to meet the requirements of high-precision soldering. At the same time, the patent documents cited above do not propose any relevant solutions to solve the above problems. Therefore, a foldable soldering iron structure is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a foldable soldering iron structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable soldering iron structure, including a handle, a turntable base at the front end of the handle, a fixing seat one on the outer wall of the turntable base, and a fixing seat two connected to the fixing seat one via a rotating shaft, a soldering head fixedly disposed on one side of the fixing seat two, and a positioning rod threadedly connected to the fixing seat one and the fixing seat two.

[0006] Preferably, both the inner rings of the first and second fixed bases are equipped with electromagnets, and a rotating shaft is provided on one side of the turntable base.

[0007] Preferably, the handle is covered with a flame-retardant layer, which is made of heat-insulating and flame-retardant plastic.

[0008] Preferably, the handle has a heating chamber inside, and the heating chamber has a temperature-regulating heating tube inside.

[0009] Preferably, the welding head has heat dissipation holes evenly spaced on one side, and the welding head is made of nickel-plated copper.

[0010] Preferably, a heat insulation layer is provided on the outer side of the turntable base, and the heat insulation layer is made of ceramic material.

[0011] Preferably, a heat-conducting layer is provided on the inner side of the heat insulation layer, and the heat-conducting layer is made of graphite heat-conducting material.

[0012] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this foldable soldering iron structure is fixed by a threaded connection of positioning rods. Fixing base one and fixing base two form a rotating base through a rotating shaft, ensuring the flexibility of angle adjustment when folding and unfolding. When the soldering head is unfolded to the target working angle, positioning rods of different specifications are screwed into the corresponding screw holes of fixing base one and fixing base two through threads, and the two fixing bases are rigidly locked. The self-locking property of the threaded connection can prevent the angle from loosening due to vibration or external force, and fully meet the stability requirements of high-precision welding scenarios.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 As attached Figures 1 to 4The folding soldering iron structure shown includes a handle 1, a turntable base 5 at the front end of the handle 1, a fixing seat 8 on the outer wall of the turntable base 5, and a fixing seat 9 connected to the fixing seat 8 via a rotating shaft. A soldering head 6 is fixedly mounted on one side of the fixing seat 9, and a positioning rod 10 is threadedly connected inside the fixing seat 8 and the fixing seat 9.

[0020] Among them: a double base is set with a first fixed base 8 and a second fixed base 9 to realize the folding and fixing of the welding head 6. The first fixed base 8 is connected to the turntable base 5, and the second fixed base 9 is connected to the welding head 6. When unfolded, it is locked by the positioning rod 10 and the electromagnet 11 to form a rigid support. When folded, it rotates around the rotating axis to drive the welding head 6 to fit against the handle 1, reducing the overall length.

[0021] Example 2 Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, both the inner rings of the first fixed base 8 and the second fixed base 9 are provided with electromagnets 11, and a rotating shaft 14 is provided on one side of the turntable base 5; furthermore, by providing electromagnets 11, a magnetic field is generated after being energized to attract the metal base, thereby compensating for any small gaps that may exist in the threaded connection.

[0022] As a preferred embodiment, a flame-retardant layer 2 is sleeved on the outside of the handle 1. The flame-retardant layer 2 is made of heat-insulating and flame-retardant plastic. Furthermore, by providing the flame-retardant layer 2 and using high-temperature resistant flame-retardant materials, residual heat penetrating from the inside of the handle 1 is directly blocked.

[0023] In a preferred embodiment, a heating chamber 3 is provided inside the handle 1, and a temperature-adjustable heating tube 4 is provided inside the heating chamber 3; furthermore, by providing a temperature-adjustable heating tube 4, it is possible to adapt to solders with different melting points, so as to avoid burning electronic components due to excessively high temperature or causing poor soldering due to excessively low temperature.

[0024] In a preferred embodiment, heat dissipation holes 7 are provided at equal intervals on one side of the solder head 6, and the solder head 6 is made of nickel-plated copper. Furthermore, by providing heat dissipation holes 7, solder splashing or component heat damage caused by the continuous rise in temperature of the solder head 6 during long-term soldering can be prevented.

[0025] As a preferred embodiment, a heat insulation layer 12 is provided on the outer side of the turntable base 5. The heat insulation layer 12 is made of ceramic material. Furthermore, by providing the heat insulation layer 12, the temperature of the user contact area is ensured to be safe during soldering, thus solving the problem of the traditional soldering iron spindle being too hot to handle.

[0026] In a preferred embodiment, a heat-conducting layer 13 is provided on the inner side of the heat insulation layer 12. The heat-conducting layer 13 is made of graphite heat-conducting material. Furthermore, by providing the heat-conducting layer 13, the heating tube and the fixing base can be tightly attached to each other, reducing heat transfer loss.

[0027] The working process of this utility model is as follows: When storing the soldering iron, first rotate the positioning rod 10, which passes through the fixing base 8 and the fixing base 9, in the opposite direction. This will cause the positioning rod 10 to unscrew from the threaded holes of the two fixing bases, releasing the rigid lock on the two fixing bases. If the electromagnet 11 was previously in an energized state, the power supply to the electromagnet 11 must be turned off first to eliminate its magnetic attraction force on the fixing base. Holding the handle 1, rotate the fixing base 9 in the direction of the handle 1, using the pivot connecting the fixing base 8 and the fixing base 9 as the center of rotation. Since the soldering head 6 is fixed to one side of the fixing base 9, the soldering head 6 will rotate synchronously with the fixing base 9 until the soldering head 6 is in contact with the side of the handle 1, fitting into the tool bag for storage. Briefly power on the electromagnet 11 to activate it. Through the initial engagement of the positioning rod 10 or the magnetic attraction of the electromagnet 11, the storage process is prevented from being interrupted. The welding head 6 can be freely wiggled to prevent damage from impacts. The turntable base 5 can be finely adjusted via the rotating shaft 14 on one side to improve operational flexibility. After adjusting the welding head 6 to the target working angle, rotate the positioning rod 10 forward to fully screw it into the corresponding threaded holes of the fixing seat 1 8 and fixing seat 2 9. Utilizing the self-locking property of the threaded connection, the two fixing seats are rigidly fixed, preventing the welding head 6 from shifting due to vibration or external force during welding. Different specifications and shapes of positioning rods 10 can be used depending on the rotation angle. Powering on the electromagnets 11 on the inner rings of fixing seat 1 8 and fixing seat 2 9 activates the magnetic field generated by the electromagnets 11, which creates a magnetic attraction force on the two metal fixing seats, further enhancing the connection stability of the two fixing seats and compensating for the lack of a single... The threaded locking mechanism can accommodate minute gaps, making it particularly suitable for high-precision welding applications. After confirming the angle of the welding head 6 is fixed, the power is turned on, and the temperature-adjustable heating tube 4 in the heating chamber 3 inside the handle 1 begins to heat up. The power of the heating tube is adjusted via the external temperature control knob to achieve precise temperature control of the welding head 6, adapting to the melting point requirements of different solder materials. The heat generated by the temperature-adjustable heating tube 4 is first transferred to the heat-conducting layer 13 inside the turntable base 5. Due to the high thermal conductivity of graphite, the heat is quickly transferred through the heat-conducting layer 13 to the fixing base 8 and fixing base 9, and finally conducted to the nickel-plated copper welding head 6. The copper material can quickly store heat, and the nickel plating layer can reduce the oxidation of the welding head 6 and extend its service life. When the temperature of the welding head 6 reaches the set value, the welding head 6 can be used to dip into the solder. Electronic components are soldered. During the soldering process, the threaded locking of the positioning rod 10 and the magnetic attraction of the electromagnet 11 work together to ensure that the angle of the soldering head 6 remains stable, avoiding problems such as incomplete soldering or missing soldering caused by angle deviation. During soldering, the heat insulation layer 12 on the outside of the turntable seat 5 can block the heat from being transferred to the handle 1. At the same time, the flame-retardant layer 2 on the outside of the handle 1 further isolates residual heat, preventing the user from being burned when holding the handle 1 and ensuring operational safety. If the soldering time is too long and the temperature of the soldering head 6 becomes too high, the heat dissipation holes 7 set at equal intervals on one side of the soldering head 6 can quickly dissipate some heat through air convection. With the power adjustment of the temperature-regulating heating tube 4, the temperature of the soldering head 6 can be dynamically balanced, preventing the soldering head 6 from being damaged by overheating or the electronic components from burning out due to excessive temperature.

[0028] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
