Description

Technical Field

[0001] This application relates to the field of welding equipment technology, and in particular to a welding device that is easy to use. Background Technology

[0002] A welding torch is the part used in the welding process to perform the welding operation. It is a tool used for gas welding, shaped like a gun, with a nozzle at the front that sprays out a high-temperature flame as a heat source. Currently, welding torches are typically used by workers who hold the handle directly, aim the nozzle at the area to be welded, and then press the switch.

[0003] However, in actual working conditions, when welding operations need to be carried out in a narrow working environment, such as welding internal parts to the inner wall of a small tank, since personnel cannot directly enter the tank, workers usually need to reach into the tank to operate the welding gun. This is inconvenient and can easily obstruct the worker's vision due to their size, affecting the welding operation. In addition, for some deeper welding areas, it is impossible to hold the welding gun and aim it at the welding position, resulting in the inability to weld normally.

[0004] Therefore, there is an urgent need for a device that can perform welding in narrow areas while being easy for workers to observe. Utility Model Content

[0005] In order to facilitate welding in narrow areas without affecting the worker's observation, this application provides a welding device that is easy to use.

[0006] This application provides a user-friendly welding device, which adopts the following technical solution: An easy-to-use welding device includes a welding torch and an extension arm. One end of the extension arm is connected to the handle of the welding torch. A control switch is provided on the extension arm for controlling the opening and closing of the welding torch. A semi-transparent light shield is provided on the handle of the welding torch.

[0007] By adopting the above technical solution, the extension arm is designed to facilitate the worker's grip, thereby increasing the range of motion of the welding torch. The control switch allows the worker to control the start of the welding torch while holding the extension arm, making it easier for the worker to extend the welding torch into narrow spaces for welding. This is more convenient than the worker having to extend their arm into a narrow space to operate. At the same time, the semi-transparent light shield also helps the worker observe the welding process and effectively prevents the strong light generated by welding from stimulating or damaging the worker's eyes.

[0008] Preferably, the extension arm includes a fixed rod, a sliding tube that slides axially along the fixed rod and is mounted on the fixed rod, and a positioning bolt for positioning the sliding tube. The control switch is mounted on the fixed rod, and the end of the sliding tube away from the fixed rod is connected to the handle of the welding torch.

[0009] By adopting the above technical solution, the cooperation of the fixed rod and the sliding tube allows workers to easily adjust the length of the extension arm according to different welding positions, thereby adapting to different welding needs. The positioning bolts facilitate workers to fix the adjusted length of the extension arm to ensure normal use during the welding process.

[0010] Preferably, a connector is provided at the connection between the extension arm and the welding torch, and the control switch is electrically connected to the switch of the welding torch through the connector. A snap-fit ​​assembly is also provided between the extension arm and the handle of the welding torch, and the snap-fit ​​assembly is used to snap the extension arm and the welding torch together.

[0011] By adopting the above technical solution, the connector enables quick connection between the control switch and the switch on the welding torch, while the snap-fit ​​component ensures a stable connection between the extension arm and the welding torch, effectively preventing the welding torch from falling off the extension arm during handheld operation.

[0012] Preferably, the snap-fit ​​assembly includes a first clamp disposed on the extension arm, a first retaining ring and a second retaining ring disposed within the first clamp, the first retaining ring and the second retaining ring being respectively disposed at both ends of the first clamp in the axial direction, a first annular groove for embedding the first retaining ring being formed on the extension arm, and a second annular groove for embedding the second retaining ring being formed on the handle of the welding torch.

[0013] By adopting the above technical solution, the extension arm and welding torch handle can be detachably connected in use with the cooperation of the first clamp, the first retaining ring and the second retaining ring, which is more conducive to actual use.

[0014] Preferably, a camera is detachably connected to the welding torch, and a display screen is detachably connected to the extension arm, with the display screen electrically connected to the camera.

[0015] By adopting the above technical solution, when using the welding torch in a narrow space, it is easier for workers to observe the welding position, making it more convenient to use, with the cooperation of the camera and display screen.

[0016] Preferably, the extension arm is provided with a mounting plate for placing the display screen, a connecting rod is fixed on the mounting plate, a second clamp is detachably provided on the extension arm, a mounting rod is fixed on the second clamp, the connecting rod is rotatably connected to the mounting rod, and rotation damping is provided at the pivot of the connecting rod and the mounting rod.

[0017] By adopting the above technical solution, the display screen can be detachably connected in use with the cooperation of the second clamp, mounting plate, connecting rod and mounting rod. It also makes it easy for workers to adjust the installation angle of the display screen for easy observation.

[0018] Preferably, the handle of the welding torch is provided with an anti-slip protrusion ring, and the translucent light shield is detachably connected to the handle of the welding torch via a third clamp. The third clamp is provided with an anti-slip groove, which engages with the anti-slip protrusion ring.

[0019] By adopting the above technical solution, workers can adjust the installation position and angle of the third clamp during use to adjust the installation position and angle of the semi-transparent light shield. At the same time, the semi-transparent light shield can be removed by removing the third clamp, which facilitates the independent use of the welding torch and its storage after use.

[0020] Preferably, the third clamp is provided with an installation cylinder, and the translucent light-shielding mirror is fixed with a connecting screw, which is threadedly connected to the installation cylinder.

[0021] By adopting the above technical solution, the semi-transparent light-blocking mirror can be detachably connected through the cooperation of the connecting screw and the mounting cylinder. At the same time, the addition of the third clamp makes it easier for workers to adjust the installation angle of the semi-transparent light-blocking mirror, thus improving the practicality of the device.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When in use, the extension arm is designed to help workers hold the welding torch, thereby increasing the range of motion of the welding torch. The control switch allows workers to control the welding torch while holding the extension arm, making it easier for workers to extend the welding torch into narrow spaces for welding. This is more convenient than having workers extend their arms into narrow spaces to operate the torch. At the same time, the semi-transparent light shield also helps workers observe the welding process and effectively prevents the strong light generated by welding from stimulating or damaging the workers' eyes. 2. With the cooperation of cameras and displays, workers can easily observe the position of the welding torch in confined spaces to ensure accurate welding positioning; 3. The combination of snap-fit ​​components, third clamps, and connectors allows workers to choose to use the welding gun alone or connect the extension arm for different usage environments, thus improving the overall practicality of the device.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 This application will be described in further detail.

[0026] This application discloses a welding device that is easy to use.

[0027] Example 1: Reference Figure 1 A user-friendly welding device includes a welding torch 1 and an extension arm 2. In this application, the welding torch 1 is an argon arc welding torch, and the extension arm 2 is a stainless steel pipe structure. A control switch 3 is installed on the extension arm 2, which is electrically connected to the switch of the welding torch 1. One end of the extension arm 2 is provided with a handle 10 for easy gripping by the worker, and the other end is connected to the handle of the welding torch 1 by welding. A semi-transparent light shield 4 is also installed on the welding torch 1 to protect the worker's eyes and prevent the strong light generated during welding from directly irritating the worker's eyes. In use, the switch of the welding torch 1 is connected to the control switch 3 by an external power line, which is hidden inside the extension arm 2. The worker can hold the handle 10 of the extension arm 2, then extend the welding torch 1 into the narrow space, and then control the welding operation of the welding torch 1 by pressing the control switch 3.

[0028] Reference Figure 1 and Figure 2To facilitate workers in adjusting the length of the extension arm 2 according to different usage needs, the extension arm 2 in this application includes a fixed rod 21, a sliding tube 22, and a positioning bolt 23. The sliding tube 22 is coaxially arranged with the fixed rod 21, and one end of the sliding tube 22 is slidably disposed inside the fixed rod 21. The other end of the sliding tube 22 is connected to the handle of the welding torch 1. The sliding tube 22 slides along its own axial direction. To guide the sliding direction of the sliding tube 22, a groove 25 is provided on the fixed rod 21, and a guide bolt 26 is threadedly connected to the sliding tube 22. The guide bolt 26 passes through the groove 25 and is threadedly connected to the sliding tube 22. That is, the sliding of the sliding tube 22 is guided by the cooperation between the guide bolt 26 and the groove 25. The positioning bolt 23 is threadedly connected to the fixed rod 21, and the end of the positioning bolt 23 passes through the fixed rod 21 and abuts against the outer wall of the sliding tube 22, thereby positioning the sliding tube 22. Reference Figure 1 and Figure 2 The control switch 3 is set on the fixed rod 21. The sliding tube 22 is hollow so that the external wire of the welding gun 1 switch can pass through the sliding tube 22 and be connected to the control switch 3. In order to accommodate the increase in the length of the extension arm 2 after the sliding tube 22 slides, a certain length of the external wire can be reserved to accommodate the need to adjust the extension arm 2 to the longest length.

[0029] Example 2: Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that in this embodiment, the extension arm 2 and the handle of the welding gun 1 are detachably connected. Specifically, a connector 5 is provided between the end of the handle of the welding gun 1 and the end of the sliding tube 22 away from the fixed rod 21. That is, the plug of the connector 5 is installed at the end of the sliding tube 22, and the socket of the connector 5 is installed at the end of the handle of the welding gun 1. The connector 5 is used to realize the electrical connection between the control switch 3 and the switch on the welding gun 1. A snap-fit ​​component 6 is also provided between the sliding tube 22 and the handle of the welding gun 1. In use, simply insert the plug of the connector 5 into the socket, and then snap the sliding tube 22 and the welding gun 1 together through the snap-fit ​​component 6 to realize the connection between the extension arm 2 and the welding gun 1, while ensuring that the worker can control the welding gun 1 to perform welding by pressing the control switch 3.

[0030] Reference Figure 4 and Figure 5The snap-fit ​​assembly 6 includes a first clamp 61, a first retaining ring 62, and a second retaining ring 63. The first retaining ring 62 and the second retaining ring 63 are respectively fixed to the inner walls of the two ends of the first clamp 61 in the axial direction. Correspondingly, a first annular groove 24 is formed on the outer wall of the sliding tube 22, and a second annular groove 11 is formed on the outer wall of the welding torch 1 handle. The first retaining ring 62 is fitted into the first annular groove 24, and the second retaining ring 63 is fitted into the second annular groove 11. In use, after the worker connects the sliding tube 22 and the welding torch 1 through the connector 5, the first clamp 61 can be installed at the connection between the sliding tube 22 and the welding torch 1 handle, and the first retaining ring 62 is embedded in the first annular groove 24, and the second retaining ring 63 is embedded in the second annular groove 11. This assembly of the sliding tube 22 and the welding torch 1, through the cooperation of the first retaining ring 62 and the second retaining ring 63, further ensures the installation stability of the welding torch 1, thereby ensuring the stable use of the welding torch 1 in the subsequent welding process.

[0031] Reference Figure 3 and Figure 6 When performing welding operations in a narrow space, in order to facilitate workers to move the welding torch 1 more accurately and align it with the position to be welded, a camera 7 can be detachably connected to the welding torch 1, and a display screen 8 can be detachably connected to the fixing rod 21. The display screen 8 is electrically connected to the camera 7. In use, the camera 7 performs image recognition in the narrow space and transmits it to the display screen 8. Workers only need to observe the image information displayed on the display screen 8 to determine the position of the head of the welding torch 1. Compared with the method of directly relying on human eyes to observe the narrow space, the process of observing and judging the position of the welding torch 1 is more convenient and accurate.

[0032] Reference Figure 6 In actual use, the camera 7 can be installed in the following way: a square plate 71 is fitted on the welding torch 1, and an elastic opening 72 is opened on the square plate 71. The elastic opening 72 is connected by a locking bolt 73. In use, the size of the elastic opening 72 can be adjusted by simply turning the locking bolt 73 to control the stability of the square plate 71 on the welding torch 1. The camera 7 is installed on the square plate 71 by bolts, and the shooting end of the camera 7 is set towards the welding head of the welding torch 1.

[0033] Reference Figure 3 and Figure 7A second clamp 83 is detachably connected to the fixed rod 21. A mounting rod 84 is welded to the second clamp 83. A connecting rod 82 is rotatably connected to the top of the mounting rod 84. A mounting plate 81 is fixed to the end of the connecting rod 82 away from the mounting rod 84. The mounting plate 81 is used to place the display screen 8. Rotation damping is also provided at the rotation point of the connecting rod 82 and the mounting rod 84. In use, the worker can install the display screen 8 on the mounting plate 81 and then adjust the angle of the display screen 8 by rotating the mounting plate 81 for easy observation. The rotation damping ensures the positioning of the mounting plate 81 after rotation and the stability of the display screen 8 after angle adjustment. The second clamp 83 makes it easy for the worker to remove the display screen 8 as a whole for subsequent storage.

[0034] Reference Figure 3 and Figure 8 Furthermore, in this embodiment, the translucent light-shielding mirror 4 is detachably connected to the handle of the welding torch 1 via the third clamp 9. Specifically, an anti-slip protrusion ring 12 is provided on the handle of the welding torch 1. Multiple anti-slip protrusion rings 12 are provided, and the multiple anti-slip protrusion rings 12 are evenly spaced along the axial direction of the handle of the welding torch 1. An anti-slip groove 91 is provided on the inner wall of the third clamp 9. The anti-slip groove 91 is engaged with the anti-slip protrusion ring 12. An installation cylinder 92 is welded and fixed on the third clamp 9, and the axial direction of the installation cylinder 92 is perpendicular to the axial direction of the third clamp 9. A connecting screw 41 is welded and fixed on the translucent light-shielding mirror 4. An internal thread is provided on the inner wall of the installation cylinder 92, and the connecting screw 41 is threadedly connected to the installation cylinder 92.

[0035] Reference Figure 3 and Figure 8 When in use, the third clamp 9 can be installed at different positions on the handle of the welding gun 1 to adjust the distance between the translucent light shield 4 and the head of the welding gun 1. The anti-slip convex ring 12 and the anti-slip groove 91 ensure the stability of the third clamp 9 after it is locked. The installation cylinder 92 and the connecting screw 41 can achieve the detachable connection of the translucent light shield 4. The angle of the translucent light shield 4 can also be adjusted by rotating the angle of the connecting screw 41. The installation angle of the translucent light shield 4 can be adjusted by rotating the third clamp 9, which is suitable for different working conditions.

[0036] Reference Figure 3 Meanwhile, when welding is not required in a confined space, workers can simply remove the extension arm 2, camera 7, display screen 8, and semi-transparent light shield 4 to use the welding gun 1 alone, which also facilitates subsequent storage and increases the overall practicality of the device.

[0037] The implementation principle of this application embodiment is as follows: In use, the sliding tube 22 and the welding gun 1 handle are connected by the connector 5, and the first clamp 61 is installed at the connection between the sliding tube 22 and the welding gun 1 handle. Then, the positioning bolt 23 is tightened to disengage its end from the sliding tube 22. The worker moves the sliding tube 22 according to the different welding positions to change the length of the extension arm 2. After adjustment, the positioning bolt 23 is tightened again to make its end press against the sliding tube 22, thereby fixing the length of the extension arm 2. Then, the camera 7, the display screen 8, and the semi-transparent light shield 4 are assembled one by one. Finally, the worker can hold the end of the fixing rod 21 and insert the welding gun 1 into the narrow space. By observing the image information displayed on the display screen 8, the worker can determine the corresponding position of the welding gun 1 head and control the welding gun 1 to perform welding operations through the control switch 3. During the welding process, the worker can observe and judge the progress of the operation through the semi-transparent light shield 4. After completion, each component can be disassembled and stored. For ordinary welding environments, the worker can also directly hold the welding gun 1 to operate. The overall use is simple and convenient.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
