Description

Technical Field

[0001] The utility model relates to the technical field of grinding and rust removal, in particular to a wire wheel for a hand grinder. Background Art

[0002] A hand grinder wire wheel is a tool accessory used for handheld grinding and polishing, typically consisting of a wheel and a connector. The wheel is typically made of steel wire and is used for grinding, removing rust, sanding, and polishing various surfaces, such as metal, wood, or plastic. The connector typically features a mechanism that secures the wire wheel to the handheld grinder for easier operation. This tool is commonly used in metalworking, woodworking, and other jobs requiring finely finished surfaces.

[0003] After searching, a Chinese patent with publication number CN210232721U discloses a wire wheel. The patent records that a combined partition is provided on the end cover of the wire wheel. The combined partition can block the steel wires on the outer peripheral side of the wheel disc, preventing the steel wires on the outer side of the wire wheel from being scattered due to the bending of several steel wires on the outer peripheral side of the wheel disc, and can improve the neatness of the free ends of several steel wires of the wire wheel. The number of radial stacking of the combined partitions can be adjusted, so that the blocking height of the combined partitions on the steel wires on the outer peripheral side of the wheel disc can be adjusted, which facilitates the control of the degree of scattering of the steel wires on the outer side of the wire wheel, ensures the grinding and rust removal effect of the wire wheel, and improves the service life of the wire wheel. The end cover is detachable and can be reused, which effectively saves costs.

[0004] In this solution, the wire wheel reduces the degree of scattering of the wire by combining partitions. However, when installed on different grinders, the wire wheel cannot be adapted to different grinders due to the different sizes of the mounting shafts on the grinders. As a result, a grinder of the same model as the wire wheel needs to be used when in use, which limits its flexibility and scope of application. In order to solve this technical problem, the utility model proposes a wire wheel for a hand grinder. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In this solution, the wire wheel reduces the degree of scattering of the wire by combining partitions. However, when installed on different grinders, the wire wheel cannot be adapted to different grinders due to the different sizes of the mounting shafts on the grinders. As a result, a grinder of the same model as the wire wheel needs to be used when in use, which limits its flexibility and scope of application. In order to solve this technical problem, the utility model proposes a wire wheel for a hand grinder.

[0014] (3) Beneficial effects

[0015] The utility model provides a wire wheel for a hand grinder. It has the following beneficial effects:

[0016] (1) Shell 1 and shell 2 are an integral frame that provides stable support. The design of the inner ring and the annular groove allows for flexible installation of structural parts. The combination of the slide groove 1 and the slider controls the moving direction of the slider to keep it consistent with the slide groove. The curved surface on the slider fits tightly with the shaft and other accessories. The groove limits the movement of the annular spring to prevent it from offsetting. The annular spring provides elastic support when the slider is subjected to external force, ensuring that the slider is firmly fixed on the shaft. This design achieves a reliable fixing effect, solves the problem that traditional wire wheels cannot adapt to different hand grinders, and improves work efficiency and reliability.

[0017] (2) The brush is fixed to the housing through a clamping plate. The second slide groove and the slide column ensure the accurate position of the clamping plate when moving. The handle drives the movement of the clamping plate through the rotation of the threaded rod, thereby realizing the replacement and fixation of the brush, solving the operational difficulty and instability problems when replacing the brush, and simplifying the operation process.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] Embodiment 1: A wire wheel for a hand grinder comprises an outer shell 1, an inner cavity 10 is provided inside the outer shell 1, an inner ring 2 is fixedly connected inside the outer shell 1, an annular groove 3 is provided on the outer side wall of the inner ring 2, an annular spring 9 is provided on the outer side wall of the inner ring 2, and the annular spring 9 is engaged in the annular groove 3, two groups of sliders 5 are provided inside the inner ring 2, and two groups of slide grooves 4 are provided inside the inner ring 2, the sliders 5 correspond to the slide grooves 4, and the slider 5 is slidably connected in the slide grooves 4, a groove 6 is provided at one end of the slider 5, the groove 6 corresponds to the annular spring 9, and the annular spring 9 is inserted in the groove 6, an arcuate surface 7 is provided at the other end of the slider 5, and the rear end of the slider 5 is slidably connected in the inner cavity 10.

[0027] When the shaft is inserted into the inner ring 2, the slider 5 is displaced outward, its curved surface 7 fitting against the shaft while simultaneously pulling the annular spring 9 within the annular groove 3, tightening it. The elasticity of the annular spring 9 secures the slider 5 to the shaft, while the groove 6 restrains the annular spring 9, preventing it from shifting. The chute 1 4 limits the direction of movement of the slider 5, ensuring it remains aligned with the chute 1 4. Once the slider 5 is clamped against the shaft of the hand grinder, it is secured with a nut. This combination allows for quick installation to suit different hand grinders, making it more practical.

[0028] Embodiment 2: The difference between this embodiment and embodiment 1 is that, the bottom of the shell 1 is fixedly connected to the shell 2 8, and a brush 11 is provided inside the shell 2 8. Threaded rods 16 are threadedly connected to both sides of the outer wall of the shell 2 8, and one end of the threaded rod 16 is fixedly connected to a turning handle 15, which is provided on the outside of the shell 2 8, and the other end of the threaded rod 16 is rotatably connected to a splint 12. The brush 11 is provided between the splint 12 and the shell 2 8, and a pair of sliding columns 14 are fixedly connected to the top of the splint 12. At the same time, a pair of sliding grooves 13 are opened on the inner wall of the shell 2 8, and the sliding grooves 13 correspond to the sliding columns 14. At the same time, the sliding columns 14 are slidably connected to the inside of the sliding grooves 13, and at the same time, the splint 12 is slidably connected to the inside of the shell 2 8.

[0029] By turning the handle 15, the threaded rod 16 rotates accordingly, driving the clamping plate 12 inward. Simultaneously, the clamping plate 12 is restrained within the second chute 13 by the slide post 14, ensuring accurate movement. As the clamping plate 12 moves inward, the angle between the clamping plate 12 and the second housing 8 increases, making brush 11 replacement more convenient. To install a new brush 11, turn the handle 15 in the opposite direction, and the clamping plate 12 begins to move outward, gradually securing the brush 11, completing the installation. This coordination significantly improves work efficiency and saves costs.

[0030] When the cam 1 is in the working state, the cam 1 is rotated by the spring 7 and the spring 8 is tightened, so that the cam 1 is fixed on the workpiece 2. When the cam 1 is in the working state, the cam 1 is tightened, and the workpiece 2 is fixed on the workpiece 2. When the cam 1 is in the working state, the cam 1 is tightened, and the workpiece 2 is fixed on the workpiece 2. When the cam 1 is in the working state, the cam 1 is tightened, and the workpiece 2 is fixed on the workpiece 2. When the cam 1 is in the working state, the cam 1 is tightened, and the workpiece 2 is fixed on the workpiece 2. The brush 11 can be easily removed and replaced by the user, and the new brush 11 can be inserted between the shell 2 8 and the splint 12. The handle 15 is rotated in the opposite direction to drive the splint 12 to move outward and gradually fix the brush 11, thereby achieving the effect of installation. The cooperation between them greatly improves work efficiency and saves costs.
