Grinding disc

This creation is about a grinding disc.

Press, when the general object is to be polished or polished, in order to save time and effort, a rotating tool is used, and the rotating tool is connected with a grinding disc, which is provided with an abrasive part (such as a grinding wheel, a brush or a hair) Wheels, etc., by rotating the tool to drive the grinding member to rotate, the workpiece can be polished, polished or waxed, and the grinding disc disclosed in TWM329497 is such.

However, such conventional grinding discs are all circular disc bodies, and the shape of the discs can increase the overall weight of the grinding discs, and the heat dissipating efficiency of the grinding discs can be reduced. Moreover, the grinding discs are provided with the edges of one side of the grinding discs. It is a right angle, which is easy to cause scratches due to the direct contact of the edge of the abrasive piece with the object, and there is a drawback that needs to be improved.

Therefore, it is necessary to provide a novel and progressive grinding disc to solve the above problems.

The main purpose of the present invention is to provide a grinding disc having a disc body, the disc body being provided with at least three arc convex portions radially outward, and the at least three arc convex portions can increase the grinding area when the grinding disc rotates. In addition, the grinding disc does not increase the weight and volume, so that the purpose of weight reduction and rapid heat dissipation can be achieved, and the disc body is provided with a chamfer on the periphery of the second side, which prevents the scratching to be ground. object.

To achieve the above object, the present invention provides a grinding disc comprising a disc body. The disk body defines an axial direction and includes a first side surface and a second side surface. The first side surface is provided with a plurality of joint portions along the axial direction, and the set portion is provided for being combined with a rotating portion of a rotating tool. The second side is assembled with an abrasive member, and the disk body is provided with at least three arc convex portions radially outward.

The structural features of the present invention and the intended effects thereof will be described below by way of a preferred embodiment, but are not intended to limit the scope of the present invention.

Referring to Figures 1 through 5, there is shown a preferred embodiment of the present invention. The abrasive disk of the present invention comprises a disk body 1.

The disk body 1 defines an axial direction and includes a first side surface 11 and a second side surface 12. The first side surface 11 is provided with a plurality of connecting portions 13 along the axial direction. The connecting portion 13 is provided with a rotating tool. 5 One of the rotating portions 51 is assembled, and the second side surface 12 is assembled with an abrasive member 6, and the disk body 1 is provided with at least three arc convex portions 14 radially outward. In the embodiment, the grinding member 6 is a brush wheel. When the rotating portion 51 of the rotating tool 5 rotates, the disk body 1 can be rotated, thereby driving the grinding member 6 to rotate. An object is polished and polished.

In the embodiment, the at least three arc convex portion 14 includes a plurality of arc convex portions 14 which are continuously disposed, and an adjacent one of the arc convex portions 14 is provided with an arc concave portion 15 , and the arc convex portions 14 and the arc concave portions 15 . Forming a continuous wave shape, the arc convex portions 14 can increase the grinding area of the disk body 1 when rotating, and can reduce the weight and volume of the disk body 1, thereby achieving the purpose of light weight and rapid heat dissipation, and additionally, due to the arcs The convex portion 14 is curved, so that the object and the human body are less likely to be scratched.

Further, the disk body 1 is provided with a plurality of long grooves 16 extending in the radial direction. In the embodiment, the long grooves 16 are arcuate grooves and are arranged radially. In addition, the disk body 1 is provided with a plurality of openings 17 which are arranged in a staggered manner with the long grooves 16. With the long slots 16 and the openings 17, the disk body 1 can be increased in heat dissipation area and weight.

It is worth mentioning that the disc body 1 is provided with a chamfer 18 on the outer periphery of the second side surface 12. In detail, since the grinding member 6 is flexible, when the user places the grinding member 6 toward the When the object is pressed against the top, the abrasive member 6 is deformed to cause the outer periphery of the second side surface 12 to directly contact the object, so the chamfer 18 can avoid scratching the object.

Preferably, the connecting portion 13 is integrally extended from the first side surface 11 to have sufficient structural strength. The connecting portion 13 is provided with a threaded portion 131, and the threaded portion 131 is coupled to the rotating portion 51. Screwed. In the embodiment, the threaded portion 131 is disposed on the inner peripheral wall of the connecting portion 13 , and the threaded portion 131 is a reverse thread to prevent the threaded portion 131 and the rotating portion 51 when the rotating portion 51 is rotated in the forward direction. The phase is loose.

The second side portion 12 is further provided with a first adhesive portion 121. The polishing member 6 is further provided with a second adhesive portion 61 that is adhered to the first adhesive portion 121. The adhesive portion 121 and the second adhesive portion 61 are corresponding to the devil felt assembly, and the abrasive member 6 can be quickly disassembled.

In summary, the arc discs of the present invention can increase the grinding area of the disc body when rotating, and can reduce the weight and volume of the disc body, thereby achieving the purpose of light weight and rapid heat dissipation, and additionally, due to the arcs The convex portion is curved, so that the object and the human body are less likely to be scratched.

Moreover, when the user presses the abrasive member against the object, the abrasive member is deformed to cause the outer edge of the second side to directly contact the object, so the chamfer can avoid scratching the object.
