Description

Technical Field

[0001] The present application relates to the technical field of grinding wheels, and in particular to a lighter grinding wheel. Background Art

[0002] The grinding wheel, also known as the ratchet wheel, is an important component of a lighter. The grinding wheel is used to rub the flint in the lighter to generate sparks, thereby igniting the fuel.

[0003] In the related art, the grinding wheel includes a movable wheel, and a plurality of friction blocks are arranged on the outer surface of the movable wheel. The friction blocks are of a square structure and are distributed along the circumference of the movable wheel. The friction blocks can generate friction with the flint to ignite the fuel.

[0004] Since the friction block is a square structure, it is easy to be damaged when rubbing against the flint, and the wear resistance of the friction block is poor. Therefore, a more wear-resistant movable wheel is needed to reduce the operation of frequent replacement of the movable wheel. Utility Model Content

[0005] In order to improve the problem of easy breakage of the friction block, the present application provides a lighter grinding wheel.

[0006] The present application provides a lighter grinding wheel, which adopts the following technical solution:

[0007] A lighter grinding wheel comprises a movable wheel. The movable wheel is provided with a plurality of friction blocks, which are distributed along the circumference of the movable wheel. The cross section of the friction blocks along the circumference of the movable wheel is triangular.

[0008] By adopting the above technical solution, the circumferential cross-section of the friction block along the movable wheel is triangular, so that the pressure can be better dispersed when the friction block and the flint are rubbed, and the damage of the friction block caused by repeated friction with the flint is reduced, so that the friction block can remain stable, and the wear resistance of the movable wheel is improved, thereby reducing people's replacement of the movable wheel.

[0009] Optionally, the friction block has a first moving surface, and the first moving surface extends in a direction perpendicular to the outer surface of the movable wheel.

[0010] By adopting the above technical solution, the first moving surface extends in a direction perpendicular to the outer surface of the movable wheel, so that the fingers can better contact the first moving surface, so that the fingers can drive the movable wheel to rotate through the first moving surface.

[0011] Optionally, the friction block has a second movable surface, the second movable surface is recessed in the direction between the friction block and the movable wheel, and the first movable surface and the second movable surface are opposite to each other.

[0012] By adopting the above technical solution, the second movable surface is recessed in the direction between the friction block and the movable wheel, so that the contact area between the second movable surface and the finger is increased, allowing the finger to better adapt to the curvature of the second movable surface, thereby increasing the comfort of the finger sliding the movable wheel; at the same time, the second movable surface is recessed in the direction between the friction block and the movable wheel, making it easier for the finger to be located in the second movable surface, and because the first movable surface and the second movable surface are directly opposite to each other, the finger can abut against the first movable surface of the adjacent friction block when sliding on the second movable surface, thereby reducing the slipping of the finger on the friction block and improving the accuracy of rotating the movable wheel.

[0013] Optionally, the edge of the friction block away from the movable wheel has a chamfer.

[0014] By adopting the above technical solution, during the rotation of the friction block, the edge of the friction block away from the movable wheel abuts against the flint. Since the edge of the friction block away from the movable wheel has a chamfer, the friction between the friction block and the flint is more uniform and stable, making ignition smoother and more reliable; at the same time, the accidental scratches caused by people's fingers abutting against the edge of the friction block away from the movable wheel are reduced, thereby improving the safety of the movable wheel.

[0015] Optionally, the friction blocks are divided into multiple groups, and the multiple groups of friction blocks are distributed along the width direction of the movable wheel.

[0016] By adopting the above technical solution, multiple groups of friction blocks are distributed along the width direction of the movable wheel, so that multiple groups of friction blocks can rub the flint, avoiding problems with a certain flint that cause the friction blocks to be unable to rub the flint, and increasing the reliability of the friction blocks in stably igniting the flint.

[0017] Optionally, there is a through hole between two adjacent friction blocks.

[0018] By adopting the above technical solution, through the perforations between two adjacent friction blocks, the heat and gas generated during the friction process can be dissipated more quickly, effectively preventing the movable wheel from overheating.

[0019] Optionally, the friction block has a third movable surface on the surface facing the friction blocks of different groups, and the third movable surface is inclined between the direction toward the friction block and the direction away from the movable wheel.

[0020] By adopting the above technical solution, the third movable surface is tilted toward the friction block and away from the movable wheel, so that the gap between two adjacent groups of friction blocks is larger, and the heat dissipation between the two adjacent groups of friction blocks is further increased.

[0021] Optionally, an indicator groove is provided on the movable wheel.

[0022] By adopting the above technical solution, by setting the indicator groove on the movable wheel, the staff can better distinguish the direction of the movable wheel when installing the movable wheel, avoiding the staff installing the wrong direction and causing different hand feel.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The circumferential cross-section of the friction block along the movable wheel is triangular, so that the pressure can be better dispersed when the friction block and the flint rub, reducing the damage of the friction block due to multiple frictions, making the friction block stable, improving the wear resistance of the movable wheel, thereby reducing people's replacement of the movable wheel.

[0025] 2. The second movable surface is recessed in the direction between the friction block and the movable wheel, so that the contact area between the second movable surface and the finger is increased, allowing the finger to better adapt to the curvature of the second movable surface, thereby increasing the comfort of the finger sliding on the movable wheel; at the same time, the second movable surface is recessed in the direction between the friction block and the movable wheel, making it easier for the finger to be located on the second movable surface. Since the first movable surface and the second movable surface are directly opposite to each other, the finger can abut against the first movable surface of the adjacent friction block when sliding on the second movable surface, thereby reducing the slipping of the finger on the friction block and improving the accuracy of rotating the movable wheel.

The plurality of indicating grooves 12 are all provided on one side surface of the movable wheel 1, so that the staff can distinguish the direction of the movable wheel 1.

[0034] Reference Figure 1 A plurality of friction blocks 2 are integrally formed on the outer circumferential surface of the movable wheel 1, and the plurality of friction blocks 2 are divided into a plurality of groups. The plurality of groups of friction blocks 2 are arranged in an array along the width direction of the movable wheel 1, and the friction blocks 2 of the same group are arranged in an array along the circumference of the movable wheel 1, and the friction blocks 2 of different groups are arranged in an alternating manner.
