[0001] The utility model relates to the technical field of angle grinders, in particular to an angle-adjustable protective cover for an angle grinder. Background Art

[0002] Angle grinder, also known as angle grinder, is a handheld electric tool used for cutting and grinding. For safety during use, angle grinders are equipped with protective covers when they leave the factory. The protective covers equipped with angle grinders are semi-shield structures, that is, the inner side of the protective cover close to the angle grinder is a protective baffle, and the outer side is an open structure.

[0003] However, the existing protective cover is simple to connect and can only cover half of the grinding disc. When not in use, the grinding disc is basically in an exposed state and cannot play a protective role, causing the grinding disc to be damaged due to impact. Summary of the invention

[0006] As a preferred technical solution, a fixing seat is installed on the top surface of the protective cover, a fixing frame is installed on the fixing seat, the length and width of the inner cavity of the fixing frame match the length and width of the angle grinder shell, and multiple fixing holes are provided on both sides of the fixing frame.

[0007] As a preferred technical solution, a first screw hole is provided at the center of the baffle, a screw rod is threadedly connected in the first screw hole, a handwheel is installed at one end of the screw rod, a second screw hole is provided on the bottom surface of the angle grinder shell opposite to the screw rod, and the handwheel is arranged in a flat structure.

[0008] As a preferred technical solution, an avoidance groove is provided on the opening end surface in front of the protective cover.

[0009] As a preferred technical solution, the protective cover and the baffle are both made of stainless steel.

[0010] As a preferred technical solution, the baffle, the connecting portion and the arc-shaped plate are stamped integrally.

[0011] As a preferred technical solution, the diameter of the protective cover is set to be the same as the diameter of the baffle.

[0012] The beneficial effects of the utility model are as follows: the utility model has a simple structure, the fixing frame can be directly put on the angle grinder and fixed by screws to complete the fixation of the protective cover, and when not in use, the bottom surface and the outer ring surface of the grinding disc can be blocked by the baffle plate rotating around the torsion spring hinge, and the top of the grinding disc is blocked by the angle grinder housing, which effectively protects the grinding disc and avoids external impact.

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 and Figure 2 As shown, the utility model is an angle-adjustable angle grinder protective cover, comprising a protective cover 1 and a baffle 5, wherein the front and bottom openings of the protective cover 1 are arranged, and the baffle 5 is arranged away from the opening in the front of the protective cover 1, and a connecting groove 10 is provided on the outer side surface of the protective cover 1 facing the baffle 5, and one end of the baffle 5 protrudes opposite to the connecting groove 10 to form a connecting portion 11, and the connecting portion 11 is inserted into the connecting groove 10 and fixedly connected to the protective cover 1 by a torsion spring hinge, and an arc plate 6 is installed on the bottom surface of the baffle 5.

[0022] In this embodiment, a fixing seat 2 is installed on the top surface of the protective cover 1, and a fixing frame 3 is installed on the fixing seat 2. The length and width of the inner cavity of the fixing frame 3 match the length and width of the angle grinder shell. A plurality of fixing holes 4 are provided on both sides of the fixing frame 3. Screws can pass through the fixing holes to fix the fixing frame on the angle grinder. The angle grinder is provided with a third screw hole opposite to the fixing hole, so that the fixing frame can be locked and fixed.

[0023] In this embodiment, a first screw hole is provided at the center of the baffle 5, a screw rod 7 is threadedly connected in the first screw hole, a handwheel 9 is installed at one end of the screw rod 7, a second screw hole is provided on the bottom surface of the angle grinder shell opposite to the screw rod 7, and the handwheel 9 is arranged in a flat structure.

[0024] In this embodiment, an escape groove 8 is provided on the open end surface in front of the protective cover 1, through which the protective cover can be brought close to the driving shaft of the angle grinder, so that the protective cover can generally block the grinding disc.

[0025] In this embodiment, the protective cover 1 and the baffle 5 are both made of stainless steel, which increases the firmness and prevents rust.

[0026] In this embodiment, the baffle 5, the connecting portion 11 and the arc-shaped plate 6 are integrally stamped, which reduces the production cost and increases the production efficiency.

[0027] In this embodiment, the diameter of the protective cover 1 is set to be the same as the diameter of the baffle 5, so that after the baffle is rotated to the bottom of the protective cover, the opening at the lower end of the protective cover can be completely blocked.

[0028] When in use, the baffle is rotated with the torsion spring hinge as the center, and the rotation of the baffle drives the connection part until the baffle is rotated to the rear of the protective cover and rests on the bottom surface of the angle grinder. At this time, the screw rod is arranged opposite to the second screw hole on the angle grinder. After rotating the hand wheel, the screw rod can be driven to be threadedly connected to the second screw hole, thereby positioning the baffle after rotation to avoid affecting the grinding operation.

[0029] As attached Figure 3As shown, when not in use, the handwheel can be rotated in the opposite direction, and the screw can be driven to be screwed out of the second screw hole through the handwheel. After the screw is lost, the reverse twisting of the torsion spring hinge can automatically drive the baffle to rotate toward the protective cover until the bottom surface of the baffle is on the bottom surface of the protective cover, and the arc plate rotates to the front of the protective cover, and the bottom surface of the grinding disc can be blocked by the baffle, and the outer ring of the grinding disc can be blocked by the arc plate and the protective cover, and the top surface of the grinding disc can be blocked by the angle grinder itself, so as to effectively protect the grinding disc and avoid external impact.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
