Description

Technical Field

[0001] This utility model relates to the field of debris protection plate technology, and in particular to a magnetic protective plate for preventing welding spatter. Background Technology

[0002] Welding is a method of joining workpieces by heating or pressurizing, or both, with or without filler material. Welding spatter is extremely hot and can burn the operator's eyes, skin, and other areas. Magnetic protective shields can block most of the spatter, reducing the risk of injury. For example, without a shield, spatter may enter the eyes, causing eye injuries, severe pain, and blurred vision.

[0003] Before welding, workers need to select a magnetic protective plate with a suitable size and magnetic strength based on the shape, size, and welding location of the workpiece. By placing the protective plate close to the workpiece, its magnetism allows it to easily adhere to the surface of the workpiece or the surrounding metal frame without the need for additional tools. During welding, the protective plate effectively blocks molten metal droplets from splashing everywhere.

[0004] In existing technologies, some magnetic protective plates designed to prevent welding spatter require users to hold them for extended periods, which can easily lead to operator fatigue and difficulty in maintaining a stable protective posture for long periods, thus affecting the protective effect. This necessitates rest or constant adjustments to the grip, resulting in reduced work efficiency. Therefore, to address these shortcomings, a magnetic protective plate designed to prevent welding spatter is proposed to solve the aforementioned problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a magnetic protective plate for preventing welding spatter, aiming to improve the problem that some existing magnetic protective plates require long-term handling during use, leading to fatigue and affecting work efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A magnetic protective plate for preventing welding spatter includes an arc-shaped protective plate. Two support frames are fixedly connected to the bottom side of the arc-shaped protective plate. Support legs are slidably connected inside the support frames.

[0010] As a further description of the above technical solution:

A transmission plate is fixedly connected to the adjacent side of each of the two sliding plates.

[0012] As a further description of the above technical solution:

[0013] The two transmission plates are fixedly connected to the opposite sides of the two trapezoidal plates respectively, and the limiting frame has an inclined opening inside, and the trapezoidal plates are slidably connected to the inside of the inclined opening.

[0032] 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a magnetically attached protective plate for preventing welding spatter, comprising an arc-shaped protective plate 1 used to block welding spatter. Two support frames 2 are fixedly connected to the bottom side of the arc-shaped protective plate 1, and the support frames 2 are connected to the arc-shaped protective plate 1 via a welding process. Multiple rectangular limiting openings 3 are provided on opposite sides of the inner walls of the two support frames 2. Support legs 4 are slidably connected inside the support frames 2, allowing the support legs 4 to slide stably up and down due to the constraints of the support frames 2. Support pads 5, made of non-slip rubber, are fixedly connected to the bottom side of the support legs 4 to increase friction with the ground and ensure the stability of the protective plate.

[0034] Reference Figures 2 to 4A connecting frame 6 is fixedly connected to the adjacent sides of the two supporting legs 4, connecting the two supporting legs 4 into a whole. Power transmission components are slidably connected to both ends of the connecting frame 6, responsible for transmitting force to control the trapezoidal plate 9, allowing the protective plate to better adapt to different working conditions. Each transmission component includes a sliding plate 7, the exterior of which is slidably connected to the interior of the front and rear ends of the connecting frame 6. The connecting frame 6 restricts the sliding of the sliding plates 7, allowing them to slide stably. A transmission plate 8 is fixedly connected to the adjacent sides of the two sliding plates 7, pushing the sliding plates 7 causes the transmission plates 8 to slide synchronously. A trapezoidal plate 9 is fixedly connected to the adjacent sides of the two transmission components, the adjacent sides of the two transmission plates 8 being fixedly connected to the distant sides of the two trapezoidal plates 9, transmitting the sliding force to the trapezoidal plates 9 through the transmission plates 8. A limiting frame 10 is slidably connected to the exterior of the trapezoidal plate 9, converting the forward and backward sliding force of the trapezoidal plate 9 into a left and right sliding force. The limiting frame 10 has an inclined opening 11 inside, and the trapezoidal plate 9 is slidably connected to the inside of the inclined opening 11. Through the cooperation of the two, the position of the limiting frame 10 can be adjusted.

[0035] Two transmission components are internally slidably connected to guide rods 12, and two sliding plates 7 are internally slidably connected to the outside of guide rods 12. The sliding plates 7 restrict the guide rods 12, allowing them to slide stably. Limiting discs 13 are fixedly connected to both the front and rear sides of the guide rods 12, providing support and preventing slippage. A spring 14 is sleeved on the outside of the guide rods 12, restricting its force to ensure even distribution. The adjacent sides of the two transmission plates 8 are fixedly connected to the front and rear ends of the spring 14. During sliding, the transmission plates 8 compress the spring 14, allowing it to store elastic potential energy and subsequently exert a counterforce on the transmission plates 8 for resetting. Positioning plates 15 are fixedly connected to the distant sides of the two limiting frames 10, allowing the positioning plates 15 to slide synchronously. The external sliding connection of the positioning plate 15 is inside the limiting opening 3, which restricts the positioning plate 15 so that it can be engaged.

[0036] Reference Figure 1 , Figure 2 and Figure 5A magnetic suction plate 16 is fixedly connected to the rear end of the arc-shaped protective plate 1, which can attract debris during the welding process. Guide frames 17 are fixedly connected to both the left and right ends of the rear side of the arc-shaped protective plate 1, and are fixed by welding to provide support for the guide frames 17. A positioning rod 18 is fixedly connected inside the guide frame 17, and is fixed by welding to ensure stable guidance. A second spring 19 is sleeved on the outside of the positioning rod 18, and the spring 19 is evenly stressed by limiting its movement. The bottom end of the second spring 19 is fixedly connected to the bottom inner wall of the guide frame 17. A sliding block 20 is slidably connected to the outside of the positioning rod 18, and the sliding block 20 can slide stably up and down by the guidance of the positioning rod 18. The outside of the sliding block 20 is slidably connected inside the guide frame 17, and the guide frame 17 guides the sliding of the sliding block 20 to prevent displacement.

[0037] The bottom side of the sliding block 20 is fixedly connected to the top of the second spring 19. During the sliding process, the sliding block 20 compresses the second spring 19, allowing the second spring 19 to store elastic potential energy, which then provides a force in the opposite direction to the sliding block 20 for resetting. A scraper 21 is fixedly connected to the adjacent side of the two sliding blocks 20, and the scraper 21 cleans the welding spatter on the rear side of the arc-shaped protective plate 1. Two guide frames 17 are slidably connected to the adjacent sides of the scraper 21 on the left and right sides respectively, providing guidance for the sliding of the scraper 21. A push plate 22 is fixedly connected to the rear side of the scraper 21; pushing the push plate 22 moves the scraper 21. A collection frame 23 is fixedly connected to the bottom rear side of the arc-shaped protective plate 1, and the collection frame 23 collects the welding spatter cleaned by the scraper 21. A handle 24 is fixedly connected to the front side of the arc-shaped protective plate 1, providing a convenient grip for the operator. An observation window 25 is fixedly connected to the top of the arc-shaped protective plate 1. The observation window 25 allows the operator to observe the welding process under the cover of the protective plate.

[0038] Working principle: Based on the welding height requirements, the two sliding plates 7 are pushed to slide, which in turn drives the transmission plate 8 to slide, thereby pushing the trapezoidal plate 9 to slide. At this time, the trapezoidal plate 9 will abut against the limiting frame 10. The inclined opening 11 inside the limiting frame 10 guides the trapezoidal plate 9, allowing the two limiting frames 10 to slide towards each other. This then drives the positioning plate 15 to slide, allowing the limiting frame 10 to slide away from the limiting opening 3 inside the support frame 2. During the sliding process of the transmission plate 8, the spring 14 is also compressed, allowing the spring 14 to store elastic potential energy. A force in the opposite direction is applied to the transmission plate 8 to reset it, and then the connecting frame 6 is pushed to drive the two support legs 4 to slide. After sliding to the desired position, the push force on the sliding plate 7 is released, so that the spring 14 can be reset and the reset force is transmitted to the positioning plate 15, so that it can be locked inside the limiting opening 3, thereby adjusting the height of the support frame 2 and the support legs 4 to adapt to welding requirements of different heights, reduce fatigue of holding, and thus improve work efficiency. When the welding equipment is turned on for welding work, the magnetic suction plate 16 will attract the welding debris and prevent it from flying everywhere.

[0039] After welding, by holding the push plate 22, the scraper 21 is pushed downwards to slide against the magnetic plate 16, allowing the debris attached to the surface of the magnetic plate 16 to move downwards. As the scraper 21 slides, it also drives the two sliding blocks 20 to slide. The sliding blocks 20 compress the second spring 19, allowing the second spring 19 to store elastic potential energy. Then, the sliding blocks 20 apply a force in the opposite direction to the scraper 21 to reset it. As the scraper 21 slides, the debris is scraped away from the surface of the magnetic plate 16, and the magnetic plate 16 no longer attracts debris, allowing the splashed debris to fall into the collection frame 23, thus quickly cleaning the debris on the surface of the magnetic plate 16.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
