Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and more specifically, to a novel tabletop welding dust collector. Background Technology

[0002] Welding processes generate a large amount of fumes, which not only pollute the working environment but also harm the health of operators. For example, long-term inhalation may lead to respiratory diseases. Therefore, it is necessary to equip the site with fume extractors to absorb and treat the fumes generated during welding.

[0003] Existing fume extractors use multi-jointed flexible metal tubes with a high-temperature and corrosion-resistant rubber layer, allowing them to bend and extend flexibly for easy adjustment of the suction position. However, while these multi-jointed flexible metal tubes can bend flexibly, wear may occur at the joints during long-term and frequent bending and adjustment, resulting in reduced positioning effectiveness after bending. Under the influence of vibrations generated during the operation of the vacuum cleaner, the position of the suction hood may easily shift, causing the suction hood to fail to accurately align with the source of the fume, thus reducing the suction effect. In view of this, we propose a new type of benchtop welding fume extractor. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a new type of tabletop welding fume vacuum cleaner to solve the technical problem that the wear and tear of the current multi-joint flexible metal tube after repeated bending and adjustment leads to a decrease in the stability and accuracy of positioning, resulting in the suction hood not being able to accurately align with the position where the fume is generated.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a novel tabletop welding fume vacuum cleaner, including a vacuuming device body installed on a welding table, and fixed frames installed on both sides of the top of the welding table, a sliding member movably installed between the two fixed frames, an adjusting block movably installed on the outer wall of the sliding member, and an adjusting member movably installed on one side of the adjusting block;

[0006] The top of the main body of the vacuuming device is equipped with a flexible tube for smoking dust, and a vacuum hood is fixedly installed at the lower end of the flexible tube. A connecting block that is rotatably connected to the adjusting component is fixedly provided on the side of the vacuum hood near the adjusting component.

[0007] The sliding component includes two sliders, with a fixed rod and a limiting rod installed between the two sliders, and the fixed rod is rotatably connected to the sliders;

[0008] The adjusting block has a through hole on its side that connects to the fixing rod, and a limiting hole on its side that connects to the limiting rod.

[0009] This invention uses a fixed frame, a sliding component, an adjusting block, and an adjusting component to fix the position of the dust hood. The fixed frame and the sliding component work together to move the dust hood forward and backward. The sliding component and the adjusting block work together to move it laterally. The adjusting block and the adjusting component work together to move it vertically. The adjusting component and the connecting block work together to adjust the angle of the dust hood. This overall structure improves the stability of the dust hood's position, reduces the impact of wear on the flexible tube on the dust hood's positioning stability, maintains accurate dust collection, and achieves consistently good dust collection results.

[0010] Preferably, the surface of the fixing rod is integrally formed with a spiral strip, and the inner wall of the movable hole is provided with a spiral groove corresponding to the spiral strip.

[0011] Preferably, an L-shaped plate is fixedly provided at the bottom of the adjusting block, and a threaded rod is rotatably installed at the top of the L-shaped plate.

[0012] Preferably, the side wall of the adjusting member is provided with a threaded hole for engaging with the threaded rod, and a rotating rod that passes through the connecting block is installed between the two sides of the adjusting member.

[0013] Preferably, both ends of the rotating rod are rotatably and fixedly fitted with limiting caps that fit against the side of the adjusting member, and a resistance ring that fits against the outer edge of the limiting cap is fixedly provided on the side of the adjusting member.

[0014] Preferably, the outer edge of the limiting cap is integrally constructed with several flexible resistance teeth, and the inner wall of the resistance ring is provided with several tooth grooves that engage with the resistance teeth.

[0015] Preferably, a handle is fixedly provided between the opposite sides of the connecting block, and the cross-sectional shape of the handle is circular.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model uses a fixed frame, a sliding component, an adjusting block, and an adjusting component to fix the position of the dust hood. The fixed frame and the sliding component work together to move the dust hood forward and backward. The sliding component and the adjusting block work together to move it laterally. The adjusting block and the adjusting component work together to move it vertically. The adjusting component and the connecting block work together to adjust the angle of the dust hood. In this way, the overall structure can improve the stability of the dust hood position, reduce the phenomenon of the dust hood positioning stability being affected by the wear of the flexible tube, maintain the accuracy of the dust collection position, and achieve a continuous and good dust collection effect.

[0018] 2. This utility model also increases the resistance to movement by constructing a spiral strip on the surface of the fixed rod and cooperating with the spiral groove opened in the inner wall of the movable hole. When the connecting block is moved laterally by pulling the handle, the fixed rod can rotate under the effect of the spiral limit, thereby increasing the resistance of the adjusting block to move laterally on the outside of the sliding part. In this way, it is not easy to deviate after the position is fixed, and the stability of the connecting block alignment position is maintained.

[0019] 3. This utility model also increases the resistance to adjusting the flip angle of the dust hood by using the combination of the limiting cap and the resistance ring. With the cooperation of the resistance teeth and the tooth groove, the force required to flip the dust hood can be further strengthened, so that the dust hood can be less affected by vibration after the flip angle is adjusted, maintain a stable position, and further enhance the effect of aiming at the smoke and dust position.

[0027] like Figures 1 to 6As shown, this utility model relates to a novel tabletop welding fume vacuum cleaner, which includes a vacuuming device body 1 installed on a welding table. Fixed frames 2 are installed on both sides of the top of the welding table, and a sliding member 3 is movably installed between the two fixed frames 2. An adjusting block 4 is movably installed on the outer wall of the sliding member 3, and an adjusting member 5 is movably installed on one side of the adjusting block 4. The cooperation between the fixed frame 2 and the sliding member 3 achieves a forward and backward displacement effect; the cooperation between the sliding member 3 and the adjusting block 4 achieves a left and right displacement effect; and the cooperation between the adjusting block 4 and the adjusting member 5 achieves a vertical displacement effect.

[0028] The top of the main body 1 of the vacuuming device is equipped with a flexible tube 101 for smoking dust, and a vacuum hood 102 is fixedly installed at the lower end of the flexible tube 101. A connecting block 103 that is rotatably connected to the adjusting member 5 is fixedly provided on the side of the vacuum hood 102 near the adjusting member 5. The combination of the adjusting member 5 and the connecting block 103 can enable the vacuum hood 102 to have the effect of flipping angle adjustment.

[0029] The sliding component 3 includes two sliders 301, with a fixed rod 302 and a limiting rod 304 installed between the two sliders 301. The fixed rod 302 is rotatably connected to the sliders 301. The side of the adjusting block 4 has a through hole 401 that engages with the fixed rod 302, and the side of the adjusting block 4 also has a limiting hole 403 that engages with the limiting rod 304. The cooperation of the two allows the adjusting block 4 to maintain stable lateral movement, and the rotatable connection between the fixed rod 302 and the sliders 301 can achieve a self-rotation effect.

[0030] In an embodiment of this utility model, a spiral strip 303 is integrally formed on the surface of the fixed rod 302, and a spiral groove 402 corresponding to the spiral strip 303 is formed on the inner wall of the movable hole 401. An L-shaped plate 404 is fixedly provided at the bottom of the adjusting block 4, and a threaded rod 405 is rotatably installed on the top of the L-shaped plate 404. By combining the spiral strip 303 and the spiral groove 402, the fixed rod 302 can rotate by the spiral engagement when the adjusting block 4 is displaced, thereby increasing the resistance to the displacement of the adjusting block 4 and improving the stability of the adjusting block 4 when it is in a fixed position.

[0031] In this embodiment of the present invention, the side wall of the adjusting member 5 is provided with a threaded hole 501 that engages with the threaded rod 405. A rotating rod 502 that passes through the connecting block 103 is installed between the two sides of the adjusting member 5. Both ends of the rotating rod 502 are rotatably and fixedly installed with a limiting cap 503 that fits against the side of the adjusting member 5. A resistance ring 504 that fits against the outer edge of the limiting cap 503 is fixedly provided on the side of the adjusting member 5. The protrusion with the threaded hole 501 in the middle of the adjusting member 5 is located in the limiting groove 406 on the side of the adjusting block 4. This can improve the tightness of the connection between the two, so that the adjusting member 5 can move up and down smoothly under the cooperation of the threaded rod 405 and the threaded hole 501 to achieve the effect of height adjustment. The combination of the rotating rod 502 and the connecting block 103 can make the dust cover 102 flip and adjust the angle under the limitation of the connecting block 103. The cooperation of the limiting cap 503 and the resistance ring 504 can increase the resistance of the connecting block 103 flipping.

[0032] In the embodiments of this utility model, the outer edge of the limiting cap 503 is integrally constructed with several flexible resistance teeth 505, and the inner wall of the resistance ring 504 is provided with several tooth grooves 506 that engage with the resistance teeth 505; through the cooperation of the two, the resistance to the rotation of the rotating rod 502 can be further improved, thereby strengthening the limiting effect and maintaining positional stability when the rotation stops.

[0033] In an embodiment of this utility model, a handle 104 is fixedly provided between the opposite sides of the connecting block 103, and the cross-sectional shape of the handle 104 is circular; the handle 104 facilitates the pulling of the dust cover 102 to adjust its position, and the circular design increases the comfort of holding it.

[0034] Working Principle: This embodiment provides a novel desktop welding fume vacuum cleaner. When the position of the vacuum hood 102 needs to be adjusted laterally, it can be pulled left or right by pulling the handle 104. This allows the adjusting block 4 to move laterally along the slider 301 under tension. During this movement, the slider 301 rotates due to the cooperation between the fixed rod 302 and the spiral groove 402, increasing the resistance to the lateral movement of the adjusting block 4. This ensures stable positioning during fume absorption after the adjustment, making it less susceptible to vibrations from the main body 1 of the vacuum cleaner. When the position of the vacuum hood 102 needs to be adjusted forward or backward, it can be done by pulling or pushing the handle 104 forward or backward, causing the slider 301 to move horizontally within the groove 201 on the side of the fixed frame 2. The anti-slip strip 202 further increases the resistance to the slider 301's movement, improving positioning stability. When the height of the vacuum hood 102 needs to be adjusted vertically, the rotating threaded rod 405 can be turned. The protrusion in the limiting groove 406 of the adjusting component 5 moves up or down with the cooperation of the threaded hole 501, thereby completing the height adjustment operation. The threaded cooperation can improve the accuracy of height adjustment, prevent excessive operation, and reduce the difficulty of position adjustment operation. When it is necessary to change the angle of dust suction hood 102, it can be done by pressing the handle 104 upward or pressing it in opposite directions, so that the connecting block 103 flips under the rotation of the rotating rod 502. At the same time, the limiting caps 503 set at both ends of the rotating rod 502 rotate inside the resistance ring 504. The cooperation of the resistance teeth 505 and the tooth groove 506 can increase the resistance of rotation. This can increase the resistance of return movement after the angle adjustment is completed, and strengthen the stability of the fixed position. Through the cooperation of the overall structure, the impact of repeated adjustment of the position of dust suction hood 102 on the flexible tube 101 can be reduced, so that the dust suction hood 102 can be kept in a suitable position for dust suction and is not easy to shift, thereby improving the convenience of welding operation and saving the time required to adjust the position of dust suction hood 102.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
