Description

Technical Field

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

[0002] A soldering iron is a handheld welding tool, mainly used for soldering components and wires in electronic manufacturing and electrical appliance repair. Its working principle is to use the heat generated by the current passing through the heating element (heating wire) to melt the solder for welding. The main components of a soldering iron include a heating element, a thermistor, an iron head, and a power cord. Among them, the heating element generates heat, and the thermistor is used to control and stabilize the temperature of the iron head. The iron head directly contacts the solder joint, heating the solder to a sufficient temperature to melt it and combine it with the solder joint.

[0003] In the prior art, the wires connected to the power supply of the electric soldering iron are mostly fixed together with the electric soldering iron. Since the wires are long, most of the prior art do not have the function of winding up the wires after use, which brings great inconvenience to the carrying of the electric soldering iron. At the same time, since the end of the soldering iron tip of the electric soldering iron is slender in design and the length of the electric soldering iron is long, it is easy to be squeezed when carrying, thereby causing certain damage to the soldering iron tip and affecting subsequent use. Therefore, a portable electric soldering iron is proposed to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a portable electric soldering iron. By providing a quick-release component and a winding component, the power cord can be quickly stored and the soldering iron head can be disassembled after carrying or using, thereby improving portability.

[0005] The technical solution to achieve the purpose of the utility model is: a portable electric soldering iron, comprising a handle, a hand grip head is installed at one end of the handle, a connecting head is installed at one end of the hand grip head, a ceramic heating core is arranged inside the connecting head, a high-temperature sleeve is detachably connected to the inside of the connecting head through a quick-release assembly, two grooves are provided on the inner wall of the connecting head, trapezoidal blocks are slidably connected to the inner walls of the two grooves, a pull rod is fixedly connected to one side of the two trapezoidal blocks, a spring 2 is sleeved on the surface of the two pull rods, the two ends of the two springs are respectively connected to one side of the trapezoidal block and the inner wall of the groove, and an arc-shaped limit ring is sleeved on the surface of the high-temperature sleeve.

[0006] In some embodiments, the high temperature sleeve is sleeved on the surface of the ceramic heating core, and a soldering iron tip is installed at one end of the high temperature sleeve away from the connector.

[0007] In some embodiments, an operating area is provided on the surface of the handle, a tailstock is installed at one end of the handle away from the grip, and one end of the tailstock is electrically connected to a power cord.

[0008] In some embodiments, a fixed block is fixedly connected to the surface of the handle, a plurality of through holes are opened on the upper surface of the fixed block, a plurality of inner walls of the through holes are slidably connected to sliding rods, the top ends of the plurality of sliding rods are fixedly connected to the same winding board, and a handle is fixedly connected to the upper surface of the winding board.

[0009] In some embodiments, a spring 1 is sleeved on the surface of each of the plurality of slide bars, and two ends of the spring 1 are respectively connected to the opposite surfaces of the winding plate and the fixing block.

[0010] Compared with the prior art, the present invention has the following significant advantages:

[0011] First, the utility model pulls two handles, and the two handles can drive the trapezoidal block to slide on the inner wall of the groove. The sliding of the trapezoidal block can separate from the arc-shaped limiting ring. At this point, the trapezoidal block no longer limits the arc-shaped limiting ring, and the high-temperature sleeve can drive the soldering iron head and the connector to be disassembled. After disassembly, the overall length of the electric soldering iron becomes shorter, which is more convenient to carry.

[0012] Secondly, the utility model lifts the winding plate upwards by means of a handle, and then the power cord is evenly wound around the winding plate in circles. A wire groove is provided on the surface of the winding plate, which can limit the wound wire clamp to avoid slipping and entanglement. After the winding is completed, the handle is released, and the winding plate will press the handle against the winding plate through the rebound of a spring, thereby limiting the wound power cord.

[0013] The present invention solves the problem that most existing electric soldering irons do not have the function of winding the wire after use, which brings great inconvenience to the carrying of the electric soldering iron. At the same time, since the end of the soldering iron tip of the electric soldering iron is designed to be slender and the length of the electric soldering iron is long, it is easy to be squeezed when carrying, thereby causing certain damage to the soldering iron tip.

[0021] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a portable electric soldering iron through improvement. The technical solution of the utility model is:

[0023] like Figure 1-4 As shown, a portable electric soldering iron comprises a handle 1, which is made of a plastic shell material. A hand grip 2 is installed at one end of the handle 1. The hand grip 2 can increase the contact area with the hand, so that the electric soldering iron can be held more stably when in use. A connector 3 is installed at one end of the hand grip 2, and a ceramic heating core 15 is arranged inside the connector 3. The ceramic heating core 15 inside the electric soldering iron is one of its key components, and it works by utilizing the resistance heating effect generated by current passing through the ceramic material; when current passes through the ceramic heating core 15, the ceramic material generates heat due to resistance, so that the soldering iron tip 5 can heat up rapidly. The ceramic material has high thermal conductivity and can quickly transfer heat to the surface of the soldering iron tip 5 to achieve a rapid heating effect; the interior of the connecting head 3 is detachably connected to a high-temperature sleeve 4 through a quick-release assembly. The high-temperature sleeve 4 is made of copper and can achieve rapid thermal conductivity. The inner wall of the connecting head 3 is provided with two grooves 17, and the inner walls of the two grooves 17 are slidably connected to trapezoidal blocks 18. One side of the two trapezoidal blocks 18 is fixedly connected to a pull rod 19, and the surfaces of the two pull rods 19 are sleeved with springs 20. The two ends of the two springs 20 are respectively connected to one side of the trapezoidal block 18 and the inner wall of the groove 17. The surface of the high-temperature sleeve 4 is sleeved with an arc-shaped limit ring 16, and the arc surface of the arc-shaped limit ring 16 is close to one side of the handle 1. Through the arc surface, the resistance can be reduced when the trapezoidal block 18 is squeezed during installation.

[0024] like Figure 1 and 3As shown, in one embodiment, the high temperature sleeve 4 is sleeved on the surface of the ceramic heating core 15, and the high temperature sleeve 4 is provided with a certain cavity, the inside of the cavity fits with the surface of the ceramic heating core 15, so that the high temperature sleeve 4 can be heated quickly, and a soldering iron tip 5 is installed at one end of the high temperature sleeve 4 away from the connector 3;

[0025] An operating area 8 is provided on the surface of the handle 1, and a temperature control adjustment, a switch and a temperature display screen are provided on the operating area 8. A tailstock 6 is installed at the end of the handle 1 away from the grip head 2. The tailstock 6 is made of flexible rubber material and can protect the connection between the power cord 7 and the circuit inside the handle 1. One end of the tailstock 6 is electrically connected to the power cord 7.

[0026] like Figure 1 and 2 As shown, in one embodiment, a fixed block 9 is fixedly connected to the surface of the handle 1, a plurality of through holes 10 are provided on the upper surface of the fixed block 9, a plurality of through holes 10 are slidably connected to the inner walls of the plurality of through holes 10, a sliding rod 11 is fixedly connected to the top ends of the plurality of sliding rods 11 with the same winding plate 12, a plurality of semicircular grooves are provided on the surface of the winding plate 12 for limiting the position of the winding wire hoop, a handle 14 is fixedly connected to the upper surface of the winding plate 12.

[0027] like Figure 2 As shown, in one embodiment, the surfaces of the plurality of slide bars 11 are sleeved with springs 13, and the two ends of the plurality of springs 13 are respectively connected to the opposite surfaces of the winding plate 12 and the fixing block 9.

[0028] The specific working method is as follows: when the portable electric soldering iron is carried, the winding plate 12 is first lifted upward by the handle 14, and then the power cord 7 is evenly wound around the winding plate 12 in circles. The surface of the winding plate 12 is provided with a wire groove, which can limit the winding wire hoop to avoid slipping and causing entanglement. After the winding is completed, the handle 14 is released, and the winding plate 12 will press the winding plate 12 against the handle 1 through the rebound of the spring 13, thereby limiting the wound power cord 7;

[0029] Next, pull the two handles, and the two handles can drive the trapezoidal block 18 to slide on the inner wall of the groove 17. The sliding of the trapezoidal block 18 can separate it from the arc limit ring 16. At this point, the trapezoidal block 18 no longer limits the arc limit ring 16, so that the high-temperature sleeve 4 can drive the soldering iron tip 5 and the connecting head 3 to be disassembled. After disassembly, the length of the overall soldering iron becomes shorter, which is more convenient to carry. During installation, the high-temperature sleeve 4 is directly inserted into the inside of the connecting head 3, and the arc surface of the arc limit ring 16 can directly squeeze the trapezoidal block 18, causing the trapezoidal block 18 to avoid, until the trapezoidal block 18 is stuck in the arc limit ring 16, and the installation is completed. It is easy to use and easy to carry.
