Technical Field

[0001] The utility model relates to the technical field of dust collecting devices, in particular to a foldable dust collecting hood. Background Art

[0002] During the processing of metal or alloy workpieces, welding, gas cutting and other operations are often required. In order to ensure the dust collection effect, the dust hood installed at the processing position usually needs to be installed directly above the workpiece.

[0003] However, since the sizes of the workpieces being processed are different, and the existing dust hood is generally welded on the air pipe and the position is fixed, it is affected by the size of the workpiece. If the dust hood is close to the workpiece, it will affect the dust collection range, and if the distance is far, it will affect the dust collection effect, so there are certain shortcomings.

[0004] Therefore, a foldable dust collecting hood is provided to solve the above-mentioned problems. Utility Model Content

[0010] The movable ring is fixedly connected to the dust collecting hood body, and the movable ring is slidably connected in the air duct through an opening. The movable ring is used to clamp the telescopic tube to drive the telescopic tube to contract or extend.

[0011] In order to facilitate the movement of the dust collecting hood, preferably, an extension tube is fixedly connected to the dust collecting hood body, the extension tube is sleeved outside the air duct, and the movable ring is fixedly connected to the extension tube.

[0012] In order to facilitate the fixation of the dust hood, preferably, a limiting bolt is threadedly connected to the extension tube, and the limiting bolt is used to fix the dust hood body to the air duct.

[0013] In order to facilitate the fixation of the telescopic tube, preferably, two ends of the telescopic tube are fixedly connected with a fixing ring 1 and a fixing ring 2 respectively, and the fixing ring 1 and the fixing ring 2 are fixedly connected to the air duct and the dust collecting hood body respectively.

[0014] In order to prevent the air duct from affecting the processing of the workpiece, preferably, a plurality of sets of splicing tubes are threadedly connected to the air outlet end of the air duct, and the extension tube is sleeved on the splicing tubes.

[0015] For ease of use, preferably, the empty opening is arranged on the splicing tube.

[0016] Compared with the prior art, the utility model provides a foldable dust collecting hood, which has the following beneficial effects:

[0017] The utility model can adjust the position of the dust collecting hood body under the condition of ensuring that the airflow is not lost through the cooperation of the dust collecting hood body and the telescopic tube which can be moved up and down, so as to avoid affecting the dust collecting effect and range due to position problems, and is convenient for use in workstations for processing different workpieces.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1:

[0027] Reference Figure 1-6 A foldable dust hood includes an air duct 1, a dust hood body 2, and further includes: an opening 102, which is arranged on the air duct 1; a telescopic tube 3, which is arranged in the air duct 1, one end of the telescopic tube 3 is fixedly connected in the air duct 1, and the other end of the telescopic tube 3 is fixedly connected in the dust hood body 2; a moving ring 203, which is fixedly connected to the dust hood body 2, and the moving ring 203 is slidably connected in the air duct 1 through the opening 102, and the moving ring 203 is used to clamp the telescopic tube 3, and drive the telescopic tube 3 to retract or extend. The extension tube 201 is sleeved on the outside of the air duct 1, and the movable ring 203 is fixedly connected to the extension tube 201. The extension tube 201 is threadedly connected with a limiting bolt 202, and the limiting bolt 202 is used to fix the dust hood body 2 on the air duct 1. The two ends of the telescopic tube 3 are respectively fixedly connected with a fixing ring 1 301 and a fixing ring 2 302. The fixing ring 1 301 and the fixing ring 2 302 are respectively fixedly connected to the air duct 1 and the dust hood body 2.

[0028] When the device is in use, if the height needs to be adjusted, it is only necessary to loosen the limit bolt 202 to release the fixing of the limit bolt 202 to the dust cover body 2, and then move the dust cover body 2 upward. Figure 3 As shown, the telescopic tube 3 is in the maximum extension state at this time. By moving upward at this time, the telescopic tube 3 can be moved upward and retracted under the action of the movable ring 203. The movable ring 203 is clamped on the telescopic tube 3 to facilitate the movement of the telescopic tube 3. The movement at this time can adjust the position of the dust hood body 2. After reaching the appropriate position, the limit bolt 202 can be tightened again to make the limit bolt 202 resist the air duct 1, thereby limiting the position of the dust hood body 2. Subsequently, the workpiece can be processed to avoid the position problem affecting the dust collecting effect of the dust hood.

[0029] Embodiment 2:

[0030] Reference Figure 1-6 A foldable dust hood is basically the same as Example 1, and further: a plurality of groups of splicing tubes 101 are threadedly connected to the air outlet end of the air duct 1, the extension tube 201 is sleeved on the splicing tube 101, and the empty port 102 is set on the splicing tube 101.

[0031] After moving upward to a certain position, the air duct 1 may extend out of the dust hood body 2. In this case, a splicing tube 101 needs to be provided. Multiple groups of splicing tubes 101 are threadedly connected to each other. If the splicing tube 101 extends out of the dust hood body 2, the leaking splicing tube 101 can be removed by rotating it in the reverse direction to prevent the extended splicing tube 101 from affecting the processing of the workpiece.

[0032] The utility model can adjust the position of the dust hood body 2 while ensuring that the airflow is not lost through the cooperation of the dust hood body 2 and the telescopic tube 3 which can be moved up and down, so as to avoid affecting the dust collection effect and range due to position problems, and facilitate the use of workstations for processing different workpieces.

[0033] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
