[0001] This utility model relates to the technical field of lawnmower blade structure, and in particular to a lawnmower blade structure that is easy to disassemble. Background Technology

[0002] The easy-to-disassemble lawnmower blade structure aims to simplify the blade assembly and disassembly process by optimizing the connection between the blade and the machine body, while also ensuring stability and safety. It primarily serves the daily maintenance, function switching, and troubleshooting of lawnmowers.

[0003] To address the aforementioned issues, existing patents offer solutions. Most existing lawnmower blades are connected to the lawnmower via bolts or screws. Disassembly is complex when using bolts or screws, and most existing protective structures are fixed, making it difficult to adjust the height according to the blade thickness.

[0004] Therefore, a lawnmower blade structure that is easy to disassemble is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a lawnmower blade structure that is easy to disassemble, which can solve the problem that most existing lawnmower blades are connected to the lawnmower by bolts or screws. When connected by bolts or screws, the disassembly process is relatively complicated, and most existing protective structures are fixed structures, which are not convenient for adjusting the height according to the thickness of the blade.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lawnmower blade structure that is easy to disassemble, including a lawnmower device, a limiting component fixedly connected to the bottom of the lawnmower device, a blade body provided on the surface of the limiting component, a limiting hole for cooperating with the limiting component being opened at the bottom of the blade body, and a protective component fixedly connected to the surface of the lawnmower device. The limiting component includes a frame, on the inner side of which a bidirectional threaded rod is rotatably connected. Two adjusting rods are threadedly connected to the surface of the bidirectional threaded rod. A spring rod is fixedly connected to the opposite side of each of the two adjusting rods. An L-shaped frame is fixedly connected to the opposite side of each of the two spring rods. A spring body is fixedly connected inside each of the two L-shaped frames. A limiting block that mates with a limiting hole is fixedly connected to the top of each of the two spring bodies. An internal hexagonal nut is fixedly connected to the right side of the bidirectional threaded rod.

[0007] Preferably, the protective component includes a protective shell, a sliding groove is provided on the rear side of the protective shell, a spiral rod is rotatably connected to the inner wall of the sliding groove, a sliding block is threadedly connected to the surface of the spiral rod, and an adjusting cover is fixedly connected to the rear side of the sliding block.

[0008] Preferably, the adjusting cover is made of stainless steel, and a knob is fixedly connected to the top of the screw rod.

[0009] Preferably, the protective shell has sliding grooves on both the left and right sides, and the adjusting cover has sliders fixedly connected to the left and right sides of the inner wall for use with the sliding grooves.

[0010] Preferably, an auxiliary groove is provided at the top of the inner wall of the frame, and an auxiliary block is fixedly connected to the top of each of the two adjusting rods.

[0011] Preferably, an auxiliary rod is fixedly connected to the inner wall of the auxiliary groove, and both auxiliary blocks are movably connected to the auxiliary rod.

[0012] Preferably, an inner protective cover is fixedly connected to the inner wall of the protective shell, and the inner protective cover is made of stainless steel.

[0013] Preferably, anti-slip plates are fixedly connected to the top of both L-shaped frames, and both anti-slip plates are in contact with the bottom of the blade body.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The present application sets up a combination structure of "bidirectional threaded rod + limit block" to replace the traditional bolt. During installation, only the internal hex nut needs to be rotated to adjust the distance between the adjusting rods, so that the limit block can be embedded into the limit hole of the blade body under the action of the spring body to complete the fixation. During disassembly, the nut can be rotated in the opposite direction to loosen it. There is no need to repeatedly disassemble and assemble the bolts throughout the process, which greatly simplifies the operation steps and shortens the disassembly and assembly time. 2. The protective component in this application is configured such that the screw rod is rotated by manually turning the knob, which causes the sliding block to move along the sliding groove and simultaneously drive the adjustment cover to rise and fall. The slider and the sliding groove cooperate to ensure that the adjustment cover moves smoothly. The protective height can be precisely adjusted according to the thickness of the blade body to avoid the protective height being too high and affecting the cutting or too low and causing flying objects to injure people.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: A lawnmower blade structure that is easy to disassemble includes a mowing device 1, a limiting component 2 fixedly connected to the bottom of the mowing device 1, a blade body 3 provided on the surface of the limiting component 2, a limiting hole 4 for cooperating with the limiting component 2 being provided at the bottom of the blade body 3, and a protective component 5 fixedly connected to the surface of the mowing device 1. The limiting component 2 includes a frame 201. A bidirectional threaded rod 202 is rotatably connected to the inner side of the frame 201. Two adjusting rods 203 are threadedly connected to the surface of the bidirectional threaded rod 202. A spring rod 204 is fixedly connected to the opposite side of each of the two adjusting rods 203. An L-shaped frame 205 is fixedly connected to the opposite side of each of the two spring rods 204. A spring body 206 is fixedly connected inside each of the two L-shaped frames 205. A limiting block 207 that mates with the limiting hole 4 is fixedly connected to the top of each of the two spring bodies 206. An internal hexagonal nut 208 is fixedly connected to the right side of the bidirectional threaded rod 202.

[0019] In this embodiment: the mowing device 1 serves as the mounting base and power carrier for the entire blade structure, fixing the limiting component 2 and the protective component 5, and providing cutting power to the blade body 3. It is the core component for mowing operations. The limiting component 2 limits the movement of the blade body 3. The blade body 3, the execution component for mowing, is fixed to the bottom of the mowing device 1 by the limiting component 2. During high-speed rotation, it cuts weeds and lawns. A limiting hole 4 is provided at the bottom of the blade body 3, fitting with the limiting block 207. The limiting block 207, once inserted, restricts the movement of the blade. The horizontal and vertical displacement of the body 3 is a key structure for the rapid positioning and fixing of the blade body 3. The protective component 5 limits the movement of the blade body 3. The frame 201 serves as the basic support structure for the limiting component 2, internally housing components such as the bidirectional threaded rod 202 and adjusting rod 203, providing stable installation and movement space for each part. The bidirectional threaded rod 202 can rotate inside the frame 201, and its surface threads drive the two adjusting rods 203 to move in opposite directions. It is the core transmission component for adjusting the spacing of the L-shaped frame 205, and its right side is connected to the internal hexagonal nut 20. 8. For ease of operation, an adjusting rod 203 is threadedly connected to a bidirectional threaded rod 202. The rod rotates with the bidirectional threaded rod 202, changing its position and thus moving the spring rod 204 and the L-shaped frame 205. The spring rod 204, connecting the adjusting rod 203 and the L-shaped frame 205, provides elastic deformation capability, adjusting the fit between the L-shaped frame 205 and the blade body 3. The L-shaped frame 205 serves as a support for the blade body 3, with the top for placing the blade body 3 and the inner side fitted with a spring body 206 and a limiting block 207, which limit and fix the blade body 3. 206, fixed inside the L-shaped frame 205, provides upward elastic force to the limiting block 207, allowing the limiting block 207 to be tightly embedded in the limiting hole 4 of the blade body 3, enhancing the stability of the blade. By setting the limiting block 207, under the elastic force of the spring body 206, it can be embedded in the limiting hole 4 of the blade body 3, directly realizing the positioning and locking of the blade body 3, preventing the blade body 3 from shifting during operation. By setting the internal hex nut 208, fixed on the right side of the bidirectional threaded rod 202, the bidirectional threaded rod 202 can be rotated by rotating the internal hex tool, providing a convenient operating end for adjusting the bidirectional threaded rod 202.

[0020] Specifically, such as Figure 3 As shown, the protective component 5 includes a protective shell 501. A sliding groove 502 is provided on the rear side of the protective shell 501. A spiral rod 503 is rotatably connected to the inner wall of the sliding groove 502. A sliding block 504 is threadedly connected to the surface of the spiral rod 503. An adjusting cover 505 is fixedly connected to the rear side of the sliding block 504.

[0021] Specifically, such as Figure 3As shown, the adjusting cover 505 is made of stainless steel, and a knob rod 506 is fixedly connected to the top of the screw rod 503.

[0022] Specifically, such as Figure 3 As shown, the protective shell 501 has sliding grooves 507 on both the left and right sides, and the adjusting cover 505 has sliders 508 fixedly connected to the left and right sides of the inner wall, which are used in conjunction with the sliding grooves 507.

[0023] In this embodiment: A protective shell 501 is fixed to the surface of the mowing device 1, and its interior is used to install components such as the auger 503 and the adjusting cover 505, while also blocking weeds and gravel that fly during cutting. A sliding groove 502 is provided on the rear side of the protective shell 501 to provide a track for the sliding block 504 to slide up and down, ensuring that the sliding block 504 maintains a stable trajectory when moving the adjusting cover 505. The auger 503 is rotatably connected to the inner wall of the sliding groove 502, and its surface threads can drive the sliding block 504 to move up and down. It is the core component for adjusting the height of the adjusting cover 505. A knob 506 is connected to the top for easy operation. The sliding block 504 is threadedly connected to the auger 503. Fixed to the adjustable guard 505, it moves up and down along the sliding groove 502 as the screw rod 503 rotates, thereby driving the adjustable guard 505 to rise and fall synchronously. The adjustable guard 505 is made of stainless steel and its height can be adjusted up and down with the sliding block 504. The protection range can be adjusted according to the thickness of the blade body 3 to avoid the protection being too high or too low and affecting the operation. A knob rod 506 is fixed to the top of the screw rod 503. No special tools are required. The screw rod 503 can be rotated manually to drive it to rotate, providing a convenient operating end for adjusting the height of the adjustable guard 505. By setting the sliding groove 507 and the slider 508, the slider 508 and the inner wall of the sliding groove 507 are slidably connected to ensure that the adjustable guard 505 rises and falls smoothly along a fixed trajectory.

[0024] Specifically, such as Figure 4 As shown, an auxiliary groove 6 is provided at the top of the inner wall of the frame 201, and an auxiliary block 7 is fixedly connected to the top of each of the two adjusting rods 203.

[0025] Specifically, such as Figure 4 As shown, an auxiliary rod 8 is fixedly connected to the inner wall of the auxiliary groove 6, and both auxiliary blocks 7 are movably connected to the auxiliary rod 8.

[0026] In this embodiment: by setting an auxiliary groove 6 and an auxiliary block 7, the inner walls of the auxiliary block 7 and the auxiliary groove 6 cooperate to prevent the adjusting rod 203 from tilting or deviating when rotating with the bidirectional threaded rod 202, thereby enhancing the stability of the adjusting rod 203's movement. By setting an auxiliary rod 8, which is fixed to the inner wall of the auxiliary groove 6, passes through the auxiliary block 7 and is movably connected to the auxiliary block 7, the movement trajectory of the auxiliary block 7 is further restricted, the guiding effect of the adjusting rod 203 when moving is enhanced, and the adjusting rod 203 is prevented from shaking.

[0027] Specifically, such as Figure 1 As shown, an inner protective cover 9 is fixedly connected to the inner wall of the protective shell 501. The inner protective cover 9 is made of stainless steel.

[0028] Specifically, such as Figure 2 As shown, anti-slip plates 10 are fixedly connected to the top of both L-shaped brackets 205, and both anti-slip plates 10 are in contact with the bottom of the blade body 3.

[0029] In this embodiment: by setting an inner protective cover 9, which is fixed to the inner wall of the protective shell 501 and is made of stainless steel, a double-layer protective structure is formed with the protective shell 501, enhancing the impact resistance of the protective component 5 and further blocking the splatter during cutting. By setting an anti-slip plate 10, which is fixed to the top of the L-shaped frame 205 and contacts the bottom of the blade body 3, and has anti-slip texture on the surface, the friction between the L-shaped frame 205 and the blade body 3 can be increased, preventing the blade body 3 from sliding due to vibration during operation.

[0030] Working principle: When it is necessary to install the blade body 3, the user first manually adjusts the hexagonal nut 208 to adjust the distance between the two adjusting rods 203 on the bidirectional threaded rod 202. After adjusting to the appropriate position, the user manually adjusts the blade body 3 so that the preset hole inside the blade body 3 contacts the two L-shaped brackets 205. When in contact, the two spring rods 204 adjust the position spacing of the two L-shaped brackets 205 adaptively. Then, the preset hole on the inner side of the blade body 3 contacts the surface on the opposite side of the two L-shaped brackets 205. After contact, the two spring rods 204 adjust the height of the two limiting blocks 207. The two limiting blocks 207 engage with the inner walls of the two limiting holes 4 to limit the blade body 3. For subsequent disassembly, the user manually adjusts the hexagonal nut 208 again to move the position of the two adjusting rods 203, thus allowing the blade body 3 to be disassembled.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
