Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plates for lawn mowers, in particular to an aluminum plate protective structure for lawn mowers which can be opened and closed quickly. Background Art

[0002] Lawn mowers are quite common in our daily life. They are mainly used by workers to trim lawns and gardens and cut weeds. The aluminum disc of the lawn mower is just an important component of the lawn mower. Usually, the lawn mower cuts the grass through a mowing rope, which is installed on the aluminum disc. During the mowing process, the weeds will be protected by a protective mechanism.

[0003] For example, the publication number CN212993141U discloses an aluminum disk sealing dust cover, which includes a dust cover; a dust cover, the dust cover is sealed and arranged at the narrow mouth of the dust cover; a mounting hole, the mounting hole passes through the center of the dust cover, and the mounting hole is used to install a transmission shaft; a slot, the slot is arranged on the outside of the mounting hole; an air flow groove, the air flow groove is arranged at one end of the slot, and is used for heat dissipation inside the dust cover; wherein, a guide plate that fits the shape of the air flow groove is arranged on the upper end of the dust cover, and the inner wall of the guide plate is close to the inner wall of the air flow groove; a collecting plate is also arranged at one end of the guide plate, and the collecting plate is arranged in an arc shape; the beneficial effect is that when it is in a working state, powder will be generated during processing, and the dust cover and the dust cover rotate with the aluminum disk structure. During the high-speed rotation of the dust cover, air is provided to the collecting plate to enter the guide plate, and the air flow rate near the air flow groove is increased by the guidance of the guide plate, thereby increasing the air pressure difference between the inside and outside of the dust cover, so that a more stable protective cover is formed on the air flow groove to prevent dust from entering;

[0004] However, the dust cover in the above application still has some shortcomings during use, such as the need to regularly disassemble and clean the dust cover, and the use area of ​​the dust cover is limited. It cannot be automatically unfolded to increase the use area when the aluminum disc is used, resulting in a failure to better protect weeds, thereby reducing the use effect. Therefore, we propose a lawn mower aluminum disc protection structure that can be opened and closed quickly to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a lawn mower aluminum disc protective structure that can be opened and closed quickly, so as to solve the problem that the protective structure currently on the market requires regular disassembly and cleaning of the dust cover, and the use area of ​​the dust cover is limited. When the aluminum disc is used, it cannot be automatically unfolded to increase the use area, resulting in poor protection of weeds, thereby reducing the use effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lawn mower aluminum plate protection structure that can be opened and closed quickly, comprising an aluminum plate body and a connecting shaft installed just above the aluminum plate body;

[0031] Embodiment 1:

[0032] In this embodiment, the mounting frame 3 and the aluminum plate body 1 are mounted by docking the docking block 8 and the fixing slot 9. Figure 1 and Figure 5-Figure 6 As shown:

[0033] The inner side of the mounting frame 3 is provided with a mounting structure that can be docked with the aluminum plate body 1, and the mounting structure includes a docking block 8;

[0034] The docking block 8 is installed on the inner surface of the mounting frame 3, and the docking block 8 is connected to the aluminum plate body 1 through a fixed card slot 9, and the fixed card slot 9 is opened on the aluminum plate body 1, the docking block 8 and the mounting frame 3 are welded, and the docking blocks 8 are distributed at equal angles on the inner surface of the mounting frame 3, and the size of the docking block 8 is consistent with the size of the fixed card slot 9;

[0035] When using the quickly openable and closable lawn mower aluminum disk protection structure, firstly, the mounting frame 3 and the aluminum disk body 1 are installed, a fixed slot 9 is provided on the aluminum disk body 1, and a docking block 8 is provided on the inner wall of the mounting frame 3, and the size of the docking block 8 is consistent with the size of the fixed slot 9, so the docking block 8 and the fixed slot 9 can be engaged, and the installation between the mounting frame 3 and the aluminum disk body 1 is realized by docking the docking block 8 and the fixed slot 9.

[0036] Embodiment 2:

[0037] In this embodiment, it is disclosed that the butt joint block 8 and the aluminum plate body 1 can be fixed again to make the connection between the mounting frame 3 and the aluminum plate body 1 more tightly. Figure 3-Figure 4 As shown:

[0038] The inner walls of the mounting frame 3 and the aluminum plate body 1 are both provided with a limiting groove 10, and the inner thread of the limiting groove 10 is connected with a fixing rod 11, and the depth of the limiting groove 10 on the aluminum plate body 1 is less than the thickness of the aluminum plate body 1;

[0039] Since the limiting grooves 10 are provided on the inner walls of the docking block 8 and the aluminum plate body 1, and the docking block 8 is distributed at equal angles, when the docking block 8 and the fixed slots 9 are engaged, the limiting grooves 10 on the inner walls of the docking block 8 and the limiting grooves 10 on the inner walls of the aluminum plate body 1 will be aligned with each other, so the staff can rotate the fixed plug rod 11 into the limiting groove 10 to limit and fix the docking block 8 and the aluminum plate body 1 again, thereby making the connection between the mounting frame 3 and the aluminum plate body 1 more secure, effectively preventing the phenomenon of falling during later use.

[0040] Embodiment three:

[0041] In this embodiment, the weeds can be better protected by unfolding the protection block 6. Figure 2 and Figure 7 As shown:

[0042] A mounting frame 3 is arranged outside the aluminum plate body 1, and a guard structure for protecting weeds is arranged outside the mounting frame 3, and the guard structure includes a fixed baffle 4;

[0043] The fixed baffle plate 4 is connected to the mounting frame 3 via the mounting shaft 5, and a protective block 6 is provided between the fixed baffle plate 4 and the mounting frame 3;

[0044] An elastic spring 7 is also installed between the fixed baffle 4 and the mounting frame 3, and the elastic spring 7 is located above the protective block 6, and the protective block 6 is made of flexible rubber material.

[0045] The fixed baffle 4 forms a rotating structure through the mounting shaft 5 and the mounting frame 3, and the fixed baffle 4 is distributed at equal angles on the outside of the mounting frame 3;

[0046] When the connecting shaft 2 rotates, it will drive the aluminum disk body 1 to rotate together, and the mounting frame 3 will be driven to rotate through the aluminum disk body 1. When the mounting frame 3 rotates, centrifugal force will be generated, which will cause the fixed baffle 4 to rotate. When the fixed baffle 4 rotates through the mounting shaft 5, the elastic spring 7 will be stretched, and the protective block 6 will be unfolded at the same time. The protective block 6 is made of flexible rubber material. Therefore, after the protective block 6 is unfolded, it will cooperate with the fixed baffle 4 to block the weeds splashed during mowing, effectively reducing the phenomenon of weeds splashing. Moreover, the protective blocks 6 are distributed at equal angles, which can make the blocking effect better and improve the overall use effect of the aluminum disk of the lawn mower. The above is the working process of the entire device.
