Chain saw friction plate

Abstract

The chain saw friction plate comprises an inserting rod, supporting blocks distributed at equal intervals are evenly welded to the outer side wall of the inserting rod, a stainless steel base disc is welded to one end of the inserting rod, and the side, close to the inserting rod, of the stainless steel base disc is fixedly connected with the supporting blocks. The side, away from the inserting rod, of the supporting block extends out of the edge of the stainless steel base disc and is in a protruding shape, and the stainless steel base disc is sleeved with an annular grinding wheel piece. According to the chain saw friction plate, the stainless steel base disc and the supporting block are arranged on the inserting rod, so that after the stainless steel base disc is sleeved with the annular grinding wheel, the annular grinding wheel can be fixed by screwing up the threaded rod, and therefore the annular grinding wheel can be powerfully supported by the stainless steel base disc and the supporting block when rotating; by means of the arrangement, the problem that the grinding wheel is prone to being broken when the grinding wheel rubs saw teeth of a chain of a chain saw is effectively solved, and therefore the stability and safety of the chain saw friction plate in the using process are improved.

Technical Field

[0001] The utility model relates to the technical field of friction plates, in particular to a friction plate for a chain saw. Background Art

[0002] As is known to all, after a period of use, the teeth of the chainsaw chain need to be sharpened to keep them sharp. The prior art usually uses a grinding wheel to rub the surface of the teeth, but since the teeth spacing of the chainsaw chain is small, the grinding wheel is easily broken during operation due to insufficient hardness. In addition, there is a safety hazard that a broken grinding wheel may accidentally injure a worker under the action of inertia, so the stability and safety of the friction plate when used still needs to be improved.

[0003] The above information disclosed in the Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may include information that does not constitute the prior art that is already known to one of ordinary skill in the art.

[0006] Through the above technical scheme, after the insertion rod is installed on the chuck of the electric drill, the annular grinding wheel can be first mounted on the stainless steel base plate, and then the mounted annular grinding wheel can be fixed on a plurality of evenly distributed support blocks by screwing the threaded rod into the threaded groove. As a result, after the electric drill drives the stainless steel base plate and the annular grinding wheel plate to rotate through the insertion rod, the stainless steel base plate can press the inner ring of the annular grinding wheel plate tightly, and a plurality of support blocks can strongly support the annular grinding wheel plate at the same time, thereby making the annular grinding wheel plate have higher strength and stability, and enabling the edge of the annular grinding wheel plate to rub the saw teeth of the oil saw chain more effectively.

[0007] Preferably, grooves are formed on both sides of the outer wall of the insertion rod.

[0008] The above technical solution can make it easier for the chuck of the electric drill to clamp the rod.

[0009] Preferably, a fixed plate is closely attached to a side of the annular grinding wheel away from the thread groove, and one side of the fixed plate is detachably connected to a stainless steel base plate.

[0010] Through the above technical solution, when the annular grinding wheel is mounted on the stainless steel base plate and is tightly attached to the support block, the other side of the annular grinding wheel can be clamped by installing a fixing plate, thereby further improving the stability of the annular grinding wheel during use.

[0011] Preferably, the interior of the fixing plate is evenly threaded with bolts, and threaded holes for screwing the bolts are evenly opened on a side of the stainless steel base plate away from the insertion rod.

[0012] Through the above technical solution, the fixed disk can be easily disassembled and assembled on the stainless steel base disk, thereby facilitating the replacement of the annular grinding wheel.

[0013] Preferably, one end of the threaded rod is fixedly connected with a protrusion.

[0014] The above technical solution can facilitate the screwing of the threaded rod.

[0015] Preferably, a slot is provided on one side of the protrusion.

[0016] Through the above technical solution, the wrench can be inserted into the protrusion to operate the threaded rod.

[0017] In summary, the present application includes at least one of the following beneficial effects:

[0018] The chainsaw friction plate is provided with a stainless steel base plate and a support block on the insertion rod respectively, so that after the annular grinding wheel plate is mounted on the stainless steel base plate, the annular grinding wheel plate can be fixed by tightening the threaded rod, so that the annular grinding wheel plate can be strongly supported by the stainless steel base plate and the support block when rotating; through the above arrangement, the problem that the grinding wheel plate is prone to breakage when rubbing against the saw teeth of the chainsaw chain is effectively solved, thereby improving the stability and safety of the chainsaw friction plate when in use.
