[0025] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0026] Embodiment 1

[0027] Please refer to Figures 1-5 The handheld welding machine with anti-splashing mechanism of the present embodiment comprises a handheld welding machine 4 and a mounting sleeve 3.

[0028] Handheld welding machine 4: the main tool for welding operation, used to generate high-temperature arc to melt metal and complete the welding process.

[0029] Mounting sleeve 3: the mounting sleeve 3 is the main part of the anti-splashing mechanism, connected to the handheld welding machine 4, used to support and connect other anti-splashing components. The outer ring of the mounting sleeve 3 is arranged with a plurality of inclined fixed rods 2, which provides a stable structural basis for the anti-splashing mechanism.

[0030] The fixed rod 2 is obliquely arranged at the outer ring of the mounting sleeve 3, and serves to fix and support the movable rod 1. One end of each fixed rod 2 is rotatably connected with the movable rod 1, so that the movable rod 1 can rotate by a certain angle relative to the fixed rod 2.

[0031] The movable rod 1 is rotatably connected with the fixed rod 2 at one end, and is connected with the top of the mounting sleeve 3 through the pulling rope 8 at the other end. The length of the movable rod 1 is greater than that of the fixed rod 2, so that the elastic protective fan 5 can form a larger shielding area when it is unfolded. The rotatable connection between the movable rod 1 and the fixed rod 2 enables the anti-splashing mechanism to automatically adjust the shielding range according to the direction and intensity of the splashing.

[0032] The elastic protective fan 5 is connected between every two movable rods 1, and serves to block the metal splashing. It is made of fireproof material and has high temperature resistance, which can avoid damage to the protective fan during welding. At the same time, the elastic design of the elastic protective fan 5 enables it to effectively buffer the impact force of the splashing.

[0033] The transparent protective sheet is connected between every two fixed rods 2, which ensures the clear observation of the welding position by the operator, and does not affect the welding operation due to shielding. The transparent protective sheet is usually made of transparent material with high temperature resistance and impact resistance.

[0034] One end of the pulling rope 8 is connected with one end of the movable rod 1, and the other end is detachably connected with the top of the mounting sleeve 3 through the adjusting structure. By adjusting the connection position of the pulling rope 8 and the top of the mounting sleeve 3, the angle between the movable rod 1 and the fixed rod 2 can be changed, thereby controlling the unfolding and retracting degree of the elastic protective fan 5 and realizing flexible adjustment of the shielding range.

[0035] The adjusting structure includes a connecting plate 6 and a plurality of adjusting rings 12. The connecting plate 6 is bolted and fixedly connected with the outer ring of the mounting sleeve 3, providing stable support for the adjusting rings 12. The adjusting rings 12 are connected at the top of the connecting plate 6, providing a detachable connection point for the pulling rope 8. By adjusting the connection of the pulling rope 8 with different positions of the adjusting rings 12, the angle of the movable rod 1 can be adjusted.

[0036] The outer ring of the mounting sleeve 3 has a plurality of obliquely arranged fixed rods 2, one end of each fixed rod 2 is rotatably connected with the movable rod 1, and one end of the movable rod 1 is connected with the top of the mounting sleeve 3 through the pulling rope 8;

[0037] The elastic protective fan 5 is connected between every two movable rods 1, and the transparent protective sheet is connected between every two fixed rods 2. One end of the pulling rope 8 is detachably connected with the top of the mounting sleeve 3 through the adjusting structure.

[0038] Embodiment 2

[0039] Please refer to Figures 1-5 As shown in the figure, the length of the movable rod 1 is greater than the length of the fixed rod 2, and the elastic protective fan 5 is made of fireproof material. Specifically, by setting the length of the movable rod 1 to be greater than the length of the fixed rod 2, the elastic protective fan 5 can form a larger shielding area when it is deployed, thereby more effectively blocking metal splashes. At the same time, the elastic protective fan 5 is made of fireproof material, which enhances its high-temperature resistance and avoids damage to the protective fan during welding due to high temperature, further improving the safety and reliability of the anti-splashing mechanism. This design not only improves the anti-splashing effect, but also prolongs the service life of the anti-splashing mechanism.

[0040] One end of the fixed rod 2 is fixedly connected with a rotating sleeve 10, and one end of the movable rod 1 is fixedly connected with a rotating ball 9 rotatably connected with the inside of the rotating sleeve 10. Specifically, by setting the rotating sleeve 10 and the rotating ball 9, flexible rotational connection between the movable rod 1 and the fixed rod 2 is achieved. This design allows the movable rod 1 to freely rotate when impacted by metal splashes, effectively buffering and dispersing the impact force and protecting the elastic protective fan 5 and the transparent protective sheet from damage. At the same time, it also ensures the stability and reliability of the anti-splashing mechanism during welding.

[0041] Embodiment 3

[0042] Please refer to Figures 1-5 As shown in the figure, the adjustment structure of the handheld welding machine with an anti-splashing mechanism includes a connecting plate 6 fixedly connected with the outer circle of the mounting sleeve 3 and a plurality of adjustment rings 12 connected to the top of the connecting plate 6. The adjustment ring 12 is connected to the top of the connecting plate 6. Specifically, by setting the connecting plate 6 and the adjustment ring 12, a stable connection point is provided for the pulling rope 8, allowing the operator to more conveniently adjust the connection position of the pulling rope 8 to the top of the mounting sleeve 3. This design simplifies the adjustment operation, improves the adjustment accuracy, and allows the shielding range of the anti-splashing mechanism to more accurately adapt to different welding requirements.

[0043] One end of the movable rod 1 is fixedly connected with a fixed ring 7, and both ends of the pulling rope 8 are fixedly connected with a connecting hook 11 for connecting with the fixed ring 7 or the adjustment ring 12. Specifically, by setting the fixed ring 7 and the connecting hook 11, the connection operation between the pulling rope 8 and the movable rod 1 and the adjustment ring 12 is simplified. The operator only needs to hang the connecting hook 11 on the fixed ring 7 or the adjustment ring 12 to complete the connection without the need for additional fixing tools or steps. This design improves the adjustment efficiency, allowing the operator to more quickly adjust the shielding range of the anti-splashing mechanism.

[0044] The plurality of adjusting rings 12 are linearly arranged along the horizontal direction of the connecting plate 6, and the plurality of elastic protective flaps 5 are combined to form a fan-shaped shielding structure. Specifically, through the linear arrangement of the adjusting rings 12 and the fan-shaped combination of the elastic protective flaps 5, the anti-splashing mechanism can form a more uniform and continuous shielding surface when it is unfolded. This design not only improves the anti-splashing effect, but also enhances the stability and aesthetics of the anti-splashing mechanism. At the same time, the fan-shaped shielding structure is also more in line with the distribution characteristics of splashes during welding, and can more effectively block the threat of splashes to welding quality and operation safety.

[0045] The present scheme has the following working process:

[0046] Preparation stage: Before the welding operation starts, the operator first prepares to adjust the anti-splashing mechanism according to the shape of the welding piece, the material and the actual situation of the welding environment.

[0047] Adjust the shielding range: The operator adjusts the angle between the movable rod 1 and the fixed rod 2 by adjusting the connection position of the pulling rope 8 and the top of the mounting sleeve 3. Specifically, when the connection position of one end of the pulling rope 8 and the top of the mounting sleeve 3 is away from the fixed rod 2, the angle between the movable rod 1 and the fixed rod 2 will decrease, and the elastic protective flap 5 will retract, reducing the shielding range; on the contrary, when the connection position of the pulling rope 8 and the top of the mounting sleeve 3 is close to the fixed rod 2, the angle between the movable rod 1 and the fixed rod 2 will increase, and the elastic protective flap 5 will unfold, increasing the shielding range.

[0048] Start welding: After the adjustment is completed, the operator starts the welding operation. During the welding process, the metal splashes will impact the elastic protective flap 5. Due to the flexible rotating connection between the movable rod 1 and the fixed rod 2 through the rotating sleeve 10 and the rotating ball 9, and the elasticity of the elastic protective flap 5 itself, the splashes are effectively buffered and blocked.

[0049] Observe the welding position: At the same time, the presence of the transparent protective sheet ensures clear observation of the welding position by the operator, and does not affect the welding operation due to shielding.

[0050] Quick adjustment: If the welding requirements change, the operator can quickly adjust the connection position between the pulling rope 8 and the movable rod 1 and the adjusting ring 12 through the fixed ring 7 and the connecting hook 11, thereby quickly adjusting the shielding range of the anti-splashing mechanism.

[0051] Advantages

[0052] Convenient operation: through the detachable connection design of the pulling rope 8 and the top of the mounting sleeve 3, and the simplified connection operation of the fixing ring 7 and the connecting hook 11, the operator can easily and quickly adjust the angle between the movable rod 1 and the fixed rod 2, and then control the expansion and contraction of the elastic protective fan 5, realize the flexible adjustment of the shielding range. This design greatly improves the flexibility and adaptability of the welding operation, so that the operator can quickly adjust the anti-splashing mechanism according to different welding needs, and improves the work efficiency and operation experience.

[0053] Anti-splashing effect is enhanced: the setting that the length of the movable rod 1 is greater than that of the fixed rod 2 makes the elastic protective fan 5 form a larger shielding area when it is expanded, so as to more effectively block the metal splashes. At the same time, the elastic protective fan 5 is made of fireproof material, which enhances its high temperature resistance and avoids damage to the protective fan during welding process. In addition, under the joint action of the dynamic adjustment ability of the elastic protective fan 5 and the clear observation function of the transparent protective sheet, the possibility of splashes escaping is significantly reduced, the anti-splashing effect is further improved, and the potential harm to the welding environment and the operator is reduced.

[0054] Strong adaptability: the anti-splashing mechanism in the technical solution can adapt to various welding scenes and needs through the flexible adjustment ability of the adjusting structure. Whether it is a welding piece of different shapes and materials, or different welding environment and conditions, the operator can make the anti-splashing mechanism reach the best working state through simple adjustment operation. This adaptability makes the handheld welding machine have a wider application prospect in metal processing, mechanical manufacturing and other fields.

[0055] Stability and aesthetics are improved: through the linear array of the adjusting ring 12 and the fan-shaped combination design of the elastic protective fan 5, the anti-splashing mechanism can form a more uniform and continuous shielding surface when it is expanded. This design not only improves the anti-splashing effect, but also enhances the stability and aesthetics of the anti-splashing mechanism. At the same time, the fan-shaped shielding structure is also more in line with the splashing distribution characteristics in the welding process, which can more effectively block the threat of splashes to the welding quality and operation safety.

Those skilled in the art should understand that the present application is not limited to the above examples, and the above examples and descriptions in the specification are only the principles of the present application.
