Description

Technical Field

[0001] This utility model relates to the technical field of lawnmower flywheel plates, specifically a lawnmower flywheel plate that is easy to replace. Background Technology

[0002] A lawnmower is a mechanical tool used for trimming lawns and vegetation. It mainly consists of a blade disc, engine, wheels, running gear, blades, handle, and control unit. The lawnmower flywheel is an important component; it refers to a cam-shaped wheel on the lawnmower engine, usually mounted at the end of the engine.

[0003] A novel flywheel plate, disclosed in Chinese Patent No. CN 206111941 U, includes a body with a ring of teeth around its outer periphery. Annular protruding rings are welded to the edges of the front and rear sides of the body. A central hole is located inside the body. Six through holes are evenly distributed between the central hole and the protruding rings on both the front and rear sides of the body. These six through holes are divided into three groups, each group arranged symmetrically in pairs relative to the central hole. An inner ring is connected to the center of the central hole via three connecting rods, evenly distributed relative to the inner ring. The inner ring contains a shaft hole, and a sealing ring is provided between the shaft hole and the inner ring. The thickness of the protruding ring is three times the thickness of the body. The thicknesses of the body, inner ring, and sealing ring are consistent. This novel flywheel plate is lightweight, wear-resistant, waterproof, dustproof, has a good central shaft hole seal, a long service life, and excellent performance.

[0004] The device has six through holes evenly distributed on both the front and back sides. However, existing devices still have the following problems: most existing lawnmower flywheel plates are bolted to the end of the engine. After the bolts are fixed, the bolts need to be tightened again when the flywheel plate is disassembled for maintenance. This is inconvenient and prone to stripping, affecting the efficiency of flywheel plate replacement. Therefore, a lawnmower flywheel plate that is easy to replace is proposed. Utility Model Content

The two bevel gears 605 mesh at an angle. The left end face of the double-threaded rod 604 extends through the right side of the two sliders 606 to the left side of the two sliders 606. The top surface of the sliders 606 is fixedly connected to... A connecting block 607 is attached, and a through groove is opened on the top surface of the connecting seat 4. The top surface of the connecting block 607 slides through the inner top surface of the connecting seat 4 and the inner wall of the through groove, extending to the top of the connecting seat 4. The left side of the connecting block 607 is fixedly connected to the surface of the pressure plate 608, the rotating rod 603, and the double-threaded rod 604. Both are rotatably connected to the inner wall of the connecting seat 4 through the bearing seat. Through the connecting assembly 60, the flywheel plate 1 is positioned during installation using the dovetail block 601 and the dovetail groove. The double-threaded rod 604 drives the slider 606 to move away from each other, so that the pressure plate 608 drives the rubber pad 609 to clamp and fix the L-shaped plate 602 on the connecting seat 4, thereby realizing the installation of the flywheel plate 1. This avoids the inconvenience of maintenance caused by bolt fixing of the flywheel plate 1 and improves the replacement efficiency of the lawnmower flywheel plate.

[0034] A rubber pad 609 is fixedly connected to the bottom surface of the pressure plate 608, and the bottom surface of the rubber pad 609 is pressed and connected to the inner bottom surface of the L-shaped plate 602.
