DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 5 In an embodiment of the present invention, a dust collection hood 100 for an angle grinder includes a hood body 10 and a depth adjustment plate 20. The hood body 10 can be detachably mounted on the angle grinder shield. The depth adjustment plate 20 is used to adjust the cutting depth.

[0027] The cover body 10 is formed with a dust collection pipe 11. The dust collection pipe 11 guides the discharge of debris. The depth adjustment plate 20 is rotatably mounted to the cover body 10. The cover body 10 is provided with a first support wheel 30. The depth adjustment plate 20 is provided with a second support wheel 40. The depth adjustment plate 20 is formed with a slide groove 21. A fastening screw is fixed to the cover body 10. The fastening screw slides within the slide groove 21 to achieve rotation of the depth adjustment plate 20 relative to the cover body 10. A locking knob 50 is screwed onto the fastening screw. The locking knob 50 and the cover body 10 clamp the depth adjustment plate 20 from both sides to lock the position of the depth adjustment plate 20 relative to the cover body 10.

[0028] Specifically, the cutting depth of the saw blade of the angle grinder is adjusted by sliding the fastening screw in the slide groove to rotate the depth adjustment plate 20 relative to the cover 10. The structure is simple.

[0029] As a specific implementation manner, there are two first support wheels 30 , and the rotation axes of the two first support wheels 30 are collinearly arranged.

[0030] As a specific embodiment, there is one second support wheel 40 . The second support wheel 40 is disposed on a side of the depth adjustment plate 20 away from the cover body 10 .

[0031] As a specific embodiment, the rotation axis of the depth adjustment plate 20 relative to the cover body 10, the rotation axis of the first support wheel 30, the rotation axis of the second support wheel 40 and the axis of the fastening screw are all parallel to each other.

[0032] As a specific embodiment, a scale is provided on the notch of the chute 21. The scale is used to indicate the cutting depth.

[0033] As a specific embodiment, the cover body 10 is provided with a plurality of buckles 12. A locking bolt 60 is screwed onto the cover body 10. The buckles 12 and the locking bolt 60 clamp the cover body 10 to the angle grinder shield from both sides.

[0034] As a specific implementation, the buckle 12 is formed by punching and bending.

[0035] As a specific embodiment, there are two buckles 12 , and the two buckles 12 are symmetrically arranged with respect to the locking bolt 60 .

[0036] Specifically, the buckle 12 is engaged with the inner wall of the outer side of the angle grinder shield, and the outer side of the angle grinder is pressed by the end of the locking bolt 60. At the same time, different angles can be adjusted by rotating the base angle of the angle grinder, which helps personnel operation.

[0037] As a specific embodiment, the dust collecting pipe 11 is equipped with a dust collecting connector 70. The dust collecting connector 70 is used to connect to a vacuum cleaner.

[0038] As a specific implementation manner, the dust suction interface is configured as a rubber dust suction interface, which is mainly connected to a rubber conversion joint of a vacuum cleaner threaded hose.

[0039] This utility model's angle grinder dust hood 100 is designed specifically for large angle grinders up to 230 mm in size. This design incorporates auxiliary functions for first and second support wheels, along with a depth adjustment plate 20 for adjusting the cutting depth, to address the cutting conditions of large angle grinders where the saw blade is perpendicular to the workpiece surface. This design facilitates smooth cuts for large angle grinders and effectively reduces operator workload, considering the weight of these relatively heavy machines. It is a precise, portable, and reliable auxiliary equipment suitable for various working conditions.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0041] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
