Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plates for lawn mowers, in particular to an automatically docking aluminum plate for lawn mowers. Background Art

[0002] The aluminum disc of the lawn mower can also be called the aluminum mower disc. It is one of the important parts of the lawn mower. The mowing rope is usually installed on the aluminum disc. The rotation of the aluminum disc drives the mowing rope to rotate and cut the weeds.

[0003] For example, the publication number CN203279535U discloses a lawn mower drive shaft assembly, and in particular, a dust cover for an aluminum disk for driving a lawn mower blade. The dust cover is trumpet-shaped, and one side of the opening is connected to the dust cover seat to form a dust cover. A through hole that matches the aluminum disk cover is provided at the bottom of the dust cover, and the side is an inwardly protruding arc surface. The above structure utilizes the dust cover and the dust cover seat to form a dust cover, forming a protective cover to prevent dust and rainwater from entering the aluminum disk and protecting the aluminum disk structure. A through hole is provided at the bottom of the dust cover. This is due to the need for a compact structure. The structure is compact, and the dustproof and waterproof effects are more obvious. The inwardly protruding arc surface can effectively drain moisture or water droplets. The arc surface structure is also not conducive to dust adhesion. When the wavy groove rotates, a wind shield will be formed nearby to prevent moisture, dust and impurities from approaching, further protecting the aluminum disk and its internal components, and extending the service life.

[0004] However, the aluminum plate in the lawn mower in the above application still has some shortcomings during use. For example, it is inconvenient to dock and install the aluminum plate, which makes disassembly and assembly more troublesome. When the aluminum plate is damaged, it is inconvenient to disassemble and repair it, which brings inconvenience to the staff and reduces the use effect of the aluminum plate. Therefore, we propose an automatically docking aluminum plate for lawn mower to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1:

[0033] In this embodiment, the docking block 6 and the fixing groove 7 are engaged with each other, so that the docking rod 4 and the fixing shaft rod 5 can be engaged and limited. Figure 1-Figure 2 and Figure 5 As shown:

[0034] An aluminum plate body 3 is disposed below the outer shell 1, and a first docking structure is disposed directly above the aluminum plate body 3, and the first docking structure includes a docking rod 4, the docking rod 4 is welded and connected directly above the aluminum plate body 3, and a fixed shaft rod 5 is disposed above the docking rod 4, and the top end of the fixed shaft rod 5 is fixed to the driving shaft 2;

[0035] When using the automatic docking aluminum disc of the lawn mower, first install the outer shell 1 at the corresponding position, and provide a positioning disc 8 on the inner side of the outer shell 1, and the positioning disc 8 and the outer shell 1 are welded. Since the outer shell 1 and the drive shaft 2 are connected by bearings, and the bottom end of the drive shaft 2 is fixed to the fixed shaft rod 5, a docking rod 4 is provided just above the aluminum disc body 3, so the docking rod 4 on the aluminum disc body 3 and the fixed shaft rod 5 can be engaged and docked, and the inner wall of the fixed shaft rod 5 is provided with fixed grooves 7 with equal angles, and the outer wall of the docking rod 4 is provided with docking blocks 6 with equal angles, and the size of the docking block 6 matches the size of the fixed groove 7, so the docking block 6 and the fixed groove 7 can be engaged and limited to each other through the docking engagement between the docking block 6 and the fixed groove 7.

[0036] Embodiment 2:

[0037] In this embodiment, the second connecting block 10 and the first connecting block 9 are engaged with each other, so that the aluminum plate body 3 can be automatically positioned inside the outer shell 1. Figure 3-Figure 4 As shown:

[0038] The fixed shaft 5 and the driving shaft 2 are welded, and the driving shaft 2 and the outer shell 1 are connected by a bearing. The positioning plate 8 and the inner surface of the outer shell 1 are welded. The outer wall of the docking rod 4 is provided with a docking block 6, and the docking block 6 is connected to the fixed shaft 5 through a fixing groove 7, and the fixing groove 7 is provided on the inner wall of the fixed shaft 5. The docking block 6 and the docking rod 4 are an integrated structure, and the docking blocks 6 are distributed at equal angles, and the size of the docking block 6 is consistent with the size of the fixing groove 7;

[0039] Second connecting blocks 10 distributed at equal angles are also provided on the upper surface of the aluminum plate body 3, and first connecting blocks 9 distributed at equal angles are provided on the lower surface of the positioning plate 8. When the docking rod 4 and the fixed shaft rod 5 are docked, the second connecting block 10 will be engaged with the first connecting block 9, so that the aluminum plate body 3 is automatically positioned on the inner side of the outer shell 1, which brings convenience to the installation of the staff and saves working time.

[0040] Embodiment three:

[0041] In this embodiment, the limit block 13 is rotated along the connecting groove 14, so that the aluminum plate body 3 can be more stable when rotating. Figure 6-Figure 7 As shown:

[0042] A positioning plate 8 is installed on the inner side of the outer shell 1, and a second docking structure for re-fixing the aluminum plate body 3 is arranged below the positioning plate 8, and the second docking structure includes a first connecting block 9;

[0043] A second connecting block 10 is fixed to the upper surface of the aluminum plate body 3, and a fixing hole 11 is provided on the second connecting block 10 and the first connecting block 9, and a locking rod 12 is connected to the inner thread of the fixing hole 11, and a limit block 13 is installed on the top of the second connecting block 10 by screws, and the limit block 13 forms a rotating structure through a connecting groove 14 and a positioning plate 8, and the connecting groove 14 is provided inside the positioning plate 8, and the connecting groove 14 is in a ring shape when viewed from above, and the connecting end of the limit block 13 and the connecting groove 14 is in a "T" shape;

[0044] Since the first connecting block 9 and the second connecting block 10 are both provided with fixing holes 11, after the first connecting block 9 and the second connecting block 10 are connected, the staff can rotate the locking rod 12 into the fixing hole 11 to lock and fix the first connecting block 9 and the second connecting block 10 again, so that the aluminum plate body 3 is fixed, effectively preventing the aluminum plate body 3 from falling during use. In addition, a limiting block 13 is fixed on the top of the first connecting block 9. The limiting block 13 forms a rotating structure through the connecting groove 14 and the positioning plate 8, so that the first connecting block 9 can be limited. When the driving shaft 2 rotates, it will drive the fixed shaft rod 5 to rotate, and the fixed shaft rod 5 drives the docking rod 4 to rotate. When the docking rod 4 rotates, it will drive the aluminum plate body 3 to rotate. When the aluminum plate body 3 rotates, the limiting block 13 will rotate along the connecting groove 14, thereby ensuring the stability of the aluminum plate body 3 when it rotates. The above is the working process of the entire device.
