Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary structure technology, specifically a welding anti-spatter structure. Background Technology

[0002] During the welding process, a lot of spatter is generated. If the current or voltage is not adjusted or the operation technique is inaccurate, the spatter problem will be more serious. This spatter can easily burn the user, and the spatter tends to slag after falling, which is more troublesome to clean.

[0003] To address these issues, Chinese patent CN221848951U describes a gas shielded welding spatter shield that prevents welding slag from splashing and features a rear observation port for easy monitoring by workers. This invention has two positional states: in working mode, rotating the shield towards the nozzle blocks upward and sideways spatter, causing it to fall below the work area; for special parts where the welding torch needs to be extended, rotating the shield towards the handle avoids interference. This invention aims to prevent welding slag from splashing during gas shielded welding and reduce interference with the surrounding area. While the patent effectively prevents welding slag from splashing in all directions, as seen in the attached drawings, it still has certain technical problems. Firstly, cleaning slag inside the shield is difficult; secondly, the welding torch cannot be adjusted at multiple angles, hindering welding operations; and thirdly, it cannot effectively exhaust welding fumes.

[0004] In order to overcome the shortcomings of the existing technology, a welding anti-spatter structure is proposed, which enables easy multi-angle adjustment of the welding torch and facilitates cleaning of the protective cover. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a welding anti-spatter structure, which solves the problems of existing anti-spatter structures having limited multi-angle movement when the welding torch is fixed, and the difficulty in cleaning welding slag that splashes onto the protective cover.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding spatter prevention structure, comprising an outer frame structure and a connecting structure. The connecting structure is connected to an air extraction fan and is installed on the right side of the outer frame structure. A movable structure is installed on the connecting structure, and a welding torch is placed inside the movable structure. A multi-level protective structure is also installed inside the outer frame structure. The movable structure includes a movable column, an inner movable column, an inner ring, and an outer ring. The multi-level protective structure includes an inner plate, an inner top plate, and a mounting plate. The movable column moves within the connecting structure, and its outer end... The unit is equipped with an outer ring body, which has a circular opening running from top to bottom. An inner movable column is inserted into the circular opening. A baffle is fixedly connected to the surface of the inner movable column on the outer surface of the outer ring body. An inner ring body is installed on the inner end face of the inner movable column. The welding torch extends into the outer frame structure through the inner ring body. An inner plate is installed on both ends of the inner top plate and is inserted into the outer frame structure. A circular opening is opened on the outer surface of the inner top plate. A mounting plate is installed on the lower end face of the inner top plate, which also has a circular opening on the outer surface of the inner top plate.

[0007] Furthermore, through the above technical solution, the circular openings on the surfaces of the internal top plate and the mounting plate are arranged alternately.

[0008] Furthermore, the outer frame structure includes an outer panel, a protective cover, an inner support rod, and an exhaust pipe; the protective cover is installed on the upper end of the two sets of outer panels and covers the outer perimeter edge of the outer panels; the inner support rod is installed on the inner side of the outer panel, wherein the lower end face of the inner panel contacts the upper end face of the inner support rod; an exhaust pipe is provided on the surface of the protective cover; and a U-shaped groove is provided on the right end face of both the outer panel and the inner panel.

[0009] As a preferred technical solution, the connection structure includes a connecting pipe and nuts. The connecting pipe is set in a U-shaped groove, and two sets of nuts are provided on the surface of the connecting pipe. One set of nuts contacts the surface of the outer plate, and the other set contacts the inner surface of the inner plate.

[0010] Furthermore, a transparent plate is installed on the right end face of the protective cover via a hinge. The transparent plate has a square opening on its surface, and one side of the square opening is aligned with the inward side of the connecting pipe.

[0011] Compared with the prior art, the present invention provides a welding spatter prevention structure, which has the following beneficial effects:

[0012] 1. This structure is achieved through the appendix Figure 3 and Figure 4As can be seen, during welding, the welding torch is directly inserted into the inner movable column and then pushed inward to make the welding torch contact the workpiece to be welded, and then welding begins. At this time, the welding slag can be effectively blocked by the transparent plate, the mounting plate, and the inner top plate. Secondly, the circular openings on the surface of the mounting plate and the inner top plate are staggered, so the welding slag will not come into contact with the inner surface of the protective cover. While preventing the slag from splashing in all directions, it can also prevent the welding slag from coming into contact with the surface of the protective cover and causing the welding slag to be fixed on the inner surface of the protective cover, which would make cleaning difficult.

[0013] 2. Through the connecting pipe, movable column, inner movable column, inner ring body, and outer ring body, when the welding torch is oscillating or adjusted, firstly, the movable column can move appropriately within the connecting pipe; secondly, the movable column can move up and down; and thirdly, the inner ring body can move left and right, thereby enabling multi-angle adjustment of the welding torch and facilitating the operator's welding work.

[0014] 3. The exhaust fan can be connected to the exhaust pipe to absorb the welding fumes, which helps the operator see the welding path clearly. Secondly, the mounting plate and the internal top plate can effectively prevent welding slag from being sucked into the exhaust fan. Attached Figure Description

[0024] 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.

[0025] Example

[0026] Please see Figure 1-8 This utility model provides the following technical solution: a welding spatter prevention structure, including an outer frame structure and a connecting structure. The connecting structure is connected to an exhaust fan and is installed on the right side of the outer frame structure. A movable structure is installed on the connecting structure, and a welding torch 13 is placed inside the movable structure. A multi-level protective structure is also installed inside the outer frame structure. The movable structure includes a movable column 10, an inner movable column 11, an inner ring 12, and an outer ring 14. The multi-level protective structure includes an inner plate 5, an inner top plate 6, and a mounting plate 7. The movable column 10 moves within the connecting structure, and an outer ring is installed at the outer end of the movable column 10. 14. The outer ring body 14 has a circular opening running from top to bottom. An inner movable column 11 is inserted into the circular opening. A baffle is fixedly connected to the surface of the inner movable column 11 located on the outer surface of the outer ring body 14. An inner ring body 12 is installed on the inner end face of the inner movable column 11. The welding torch 13 extends into the outer frame structure through the inner ring body 12. The inner plate 5 is installed on both ends of the inner top plate 6. The inner plate 5 is inserted into the inner side along the outer frame structure. A circular opening is opened on the outer surface of the inner top plate 6. The mounting plate 7 is installed on the lower end face of the inner top plate 6. A circular opening is also opened on the outer surface of the inner top plate 6.

[0027] In this implementation scheme, the specific working principle is as follows: During use, the welding torch 13 is pushed along the inner ring 12 into the outer frame structure, so that the welding torch 13 contacts the workpiece to be welded. At this time, during welding, the welding slag produced will be blocked by the internal top plate 6, mounting plate 7, and inner plate 5, thereby preventing the welding slag from splashing onto the inner surface of the protective cover 2, which would cause inconvenience in cleaning the inner surface of the protective cover 2. Secondly, the movable column 10 can move inside the connecting pipe 9, thus enabling the attachment of... Figure 8As shown, the left and right sides can be adjusted appropriately. Secondly, the movable column 10 and the connecting pipe 9 are not fixedly connected, so the up and down rotation adjustment can be realized. Furthermore, the inner ring 12 can be adjusted left and right through the inner movable column 11. Therefore, the welding torch 13 can be adjusted in multiple angles through the movable structure, which greatly facilitates the operator's welding operation.

[0028] Based on the above, in order to prevent the exhaust fan from sucking up the welding slag during air intake, and secondly to prevent the welding slag from contacting the inner surface of the protective cover 2, please refer to the following for details. Figure 5 and Figure 7 As can be seen, the circular openings on the surfaces of the internal top plate 6 and the mounting plate 7 are staggered, so when the welding slag splashes, it will be intercepted by the internal top plate 6 and the mounting plate 7 through multiple protections, thereby preventing the welding slag from being sucked away by the exhaust fan, and secondly preventing the welding slag from contacting the surface of the protective cover 2.

[0029] For details regarding the outer frame structure, please refer to [link / reference needed]. Figure 1 , Figure 3-5 As can be seen, the outer frame structure includes an outer plate 1, a protective cover 2, an inner support rod 3, and an exhaust pipe 4. The protective cover 2 is installed on the upper end of the two sets of outer plates 1 and covers the outer perimeter of the outer plates 1. The inner support rod 3, which supports the inner plate 5, is installed on the inner side of the outer plate 1. The lower end face of the inner plate 5 contacts the upper end face of the inner support rod 3. The surface of the protective cover 2 is provided with an exhaust pipe 4 for easy connection to the exhaust fan. The right end faces of both the outer plate 1 and the inner plate 5 are provided with U-shaped slots for easy installation of the connecting pipe 9.

[0030] To ensure that both the outer panel 1 and the inner panel 5 can be secured simultaneously, please refer to the following for details. Figure 4 and Figure 8 As can be seen, the connecting structure includes a connecting pipe 9 and nuts. The connecting pipe 9 is set in the U-shaped groove, and there are two sets of nuts on the surface of the connecting pipe 9. One set of nuts contacts the surface of the outer plate 1, and the other set contacts the inner surface of the inner plate 5. The connecting pipe 9 is pushed into the U-shaped groove, and then the two sets of nuts on the surface of each connecting pipe 9 are clamped. The clamping force can simultaneously clamp the inner plate 5 and the outer plate 1, and prevent the connecting pipe 9 from moving. It should also be noted that the inside of the connecting pipe 9 is a cavity, which facilitates the rotation and movement of the movable column 10.

[0031] For ease of welding by the operator. See details. Figure 2 and Figure 3 As can be seen, a transparent plate 8 is installed on the right end face of the protective cover 2 via a hinge. A square opening is provided on the surface of the transparent plate 8, and one side of the square opening is aligned with the inner side of the connecting pipe 9. This provides a larger working space for the welding torch 13 during operation.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
