[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Example 1

[0029] Please see Figure 1 As shown, this utility model is a welding fume collection hood structure, including a collection hood 1. Four lifting rings 101 are fixedly connected to the top wall of the collection hood 1, which facilitates the lifting of the collection hood 1 by means of a gantry crane and ropes, thereby enabling the position to be adjusted according to the welding station position.

[0030] like Figures 2-5 As shown, the lower end of the collection cover 1 is a rectangular frame structure, and the inner walls of all four sides are rotatably connected with rollers 2. The ends of the four rollers 2 are sequentially connected for transmission. For example, each roller 2 is connected to a bevel gear at its end, and they mesh with each other, so that the four rollers 2 can drive each other and rotate synchronously.

[0031] Furthermore, one end of one of the scrolls 2 is rotatably connected to a drive device 3, which is a drive motor. The drive motor drives the four scrolls 2 to rotate. The drive device 3 may be a hand-cranked worm gear reducer. The output end of the hand-cranked worm gear reducer is connected to the scroll 2, and the four scrolls 2 are rotated by hand.

[0032] This embodiment takes a drive motor as an example. The drive motor is fixed to the outer wall of the collection cover 1 and is connected to the roller 2 via gear transmission. The roller 2 is connected to a roller blind 201. The roller blind 201 is a soft glass curtain, which can be made of transparent material or colored soft glass curtain, thereby reducing the impact of arc light generated by welding on the workshop.

[0033] The drive device 3 synchronously drives four rollers 2 to rotate, and the rollers 22 wind up the roller shutter 201 to achieve the raising and lowering of the roller shutter 201. This allows for adjustment of the raising and lowering length of the roller shutter 201 according to the height of the collection hood 1, effectively improving the overall adaptability and ensuring the collection effect of welding fumes. Furthermore, when not in use or during hoisting, the rollers 22 can also be used to wind up and store the roller shutter 201, which helps to keep the roller shutter 201 clean and improves the convenience of hoisting.

[0034] Example 2

[0035] like Figure 1 , 6 As shown in Figure 7, based on Embodiment 1, telescopic legs 4 are connected to all four side walls of the collection cover 1. The upper ends of the telescopic legs 4 are rotatably connected to the side walls of the collection cover 1. A flat-headed pin 5 is fixedly connected to the side wall of the collection cover 1, and a spring 501 is sleeved on the flat-headed pin 5 and an L-shaped hanging plate 502 is movably inserted therethrough. The lower end of the L-shaped hanging plate 502 is bent into a horizontal state and faces the collection cover 1. The spring 501 is located on the side of the L-shaped hanging plate 502 away from the collection cover 1. By pushing the L-shaped hanging plate 502 with the spring 501, the L-shaped hanging plate 502 is made to fit tightly against the outer wall of the collection cover 1.

[0036] By adjusting the length of the telescopic leg 4, the collection cover 1 is supported. When the telescopic leg 4 is not in use, the L-shaped hanging plate 502 is pulled away from the collection cover 1, and the telescopic leg 4 is rotated to a horizontal position. At this time, the L-shaped hanging plate 502 is released, and the spring 501 pushes the L-shaped hanging plate 502 so that the telescopic leg 4 rests on the L-shaped hanging plate 502. The end of the telescopic leg 4 is limited between the L-shaped hanging plate 502 and the collection cover 1 by the L-shaped hanging plate 502, thereby suspending and fixing the telescopic leg 4 and realizing the storage of the telescopic leg 4. This improves the convenience of adjusting the position of the collection cover 1 and greatly improves the overall practicality.
