Description

Technical Field

[0001] This utility model relates to the field of lawn mower technology, and in particular to an auxiliary grip structure for a lawn mower. Background Technology

[0002] A lawn mower, also known as a lawn cutter or lawn trimmer, is a type of garden machinery used to trim lawns and grassland vegetation. Its core function is to quickly and efficiently cut various herbaceous plants to keep the lawn flat and beautiful, or to clear weeds from wasteland in preparation for subsequent planting, development and other activities.

[0003] Existing lawn mowers typically have their blades mounted on the underside of the machine. This design prevents them from cutting tall grass, limiting their usability. Furthermore, the grass cut by existing lawn mowers is often quite fine, which tends to get damp and rot easily when piled up, making it difficult to preserve. The fine grass is also inconvenient to collect and reuse, resulting in a waste of resources. It is difficult to collect grass clippings scattered on the lawn, and existing lawn mowers cannot cut flattened grass, resulting in an uneven lawn trimming.

[0004] An existing patent (publication number: CN210746083U) describes a lawnmower that, by placing the blades at the front end of the lawnmower, enables it to cut taller grass, thus expanding its application range. Through the combined use of feed rollers and a conveyor belt, the cut grass is transported to the hay bin, avoiding repeated cutting by the blades and ensuring that the cut grass is relatively intact. This facilitates the bundling and transportation of the collected grass, which is beneficial for its preservation. At the same time, the cut grass can be used to feed animals, thereby improving the utilization of the grass.

[0005] The aforementioned lawn mowers generate high-frequency vibrations of varying amplitudes during operation. The original handle alone cannot effectively cushion these vibrations, allowing the vibrations to be transmitted to the hand almost without obstruction. This not only exacerbates hand soreness and discomfort but may also damage the user's hand joints and arm muscles over time. Furthermore, users vary greatly in height, arm length, and operating habits, and the fixed position of the original handle makes it difficult to meet individual grip needs. This results in some users struggling to accurately control the direction of the lawn mower, thereby reducing work efficiency and quality.

[0006] Therefore, an auxiliary gripping structure for a lawn mower is proposed. Utility Model Content

[0007] The purpose of this invention is to provide an auxiliary grip structure for a lawn mower, which can solve the problem that existing lawn mowers generate high-frequency and varying amplitude vibrations during operation. The single original handle cannot effectively buffer these vibrations, allowing the vibration to be transmitted to the hand almost without obstruction. This not only aggravates hand soreness and discomfort, but may also cause damage to the user's hand joints and arm muscles in the long run. Furthermore, different users have huge differences in height, arm length, and operating habits. The original handle has a fixed position and cannot meet the personalized grip needs. This makes it difficult for some users to accurately control the direction of the lawn mower, thereby reducing the efficiency and quality of operation.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary grip structure for a lawn mower, comprising a body, an original handle fixedly connected to the top of the body, a connecting block provided on the surface of the original handle, an adjustment component provided on the top of the connecting block, the adjustment component comprising a connecting plate, and an auxiliary grip component provided on the top of the connecting plate;

[0009] The auxiliary grip assembly includes an inner grip, which is fixedly connected to the top of the connecting plate. An outer grip is provided on the surface of the inner grip, and the interior of the inner grip is hollow. A damper is fixedly connected between the opposite sides of the outer grip and the inner grip. The number of dampers is set to multiple and evenly distributed in a ring. A shock-absorbing spring is sleeved on the surface of the damper, and the two ends of the shock-absorbing spring are fixedly connected to the inner wall of the outer grip and the surface of the inner grip, respectively.

[0010] Preferably, a mounting block is fixedly connected to the top of the connecting block, and a mounting groove is provided on the top of the mounting block. A bidirectional adjusting screw is rotatably connected inside the mounting groove. Both sides of the surface of the bidirectional adjusting screw are threadedly connected to mating blocks, and the connecting plate is fixedly connected to the top of the mating block.

[0011] Preferably, guide grooves are provided on the front and rear sides of the inner wall of the mounting groove, and a sliding rod is fixedly connected inside the guide groove. Guide blocks are fixedly connected on the front and rear sides of the mating block, and the guide blocks are slidably connected to the surface of the guide groove.

[0012] Preferably, one end of the bidirectional adjusting screw is fixedly connected to a rotating rod, and the rotating rod passes through the mounting block and is rotatably connected to the mounting block.

[0013] Preferably, the connecting block has an arc-shaped groove inside, which is used in conjunction with the original handle.

[0014] Preferably, the connecting block has a fixing screw internally threaded, and the original handle has a threaded groove inside that cooperates with the fixing screw.

[0015] Preferably, the outer grip is made of a flexible material, and the surface of the outer grip is engraved with anti-slip texture.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application incorporates an auxiliary grip component, which significantly reduces the vibration received by the outer grip, eliminating the need for hand muscles to constantly tense against vibration. This makes operating the lawn mower easier and more comfortable, and even during long lawn mowing sessions, users are less likely to experience hand fatigue, thus improving the overall working experience.

[0018] 2. This application incorporates an adjustment component that allows for flexible horizontal adjustment of the position of the auxiliary grip component. Whether the user is tall with long arms or petite, they can adjust the auxiliary grip component to the most comfortable and natural position for gripping, thus improving operational comfort and convenience, and enhancing the flexibility of use.

[0025] 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.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] An auxiliary grip structure for a lawn mower includes a body 1, an original handle 2 fixedly connected to the top of the body 1, a connecting block 3 provided on the surface of the original handle 2, an adjustment component 4 provided on the top of the connecting block 3, the adjustment component 4 including a connecting plate 401, and an auxiliary grip component 5 provided on the top of the connecting plate 401.

[0028] The auxiliary grip component 5 includes an inner grip 501, which is fixedly connected to the top of the connecting plate 401. An outer grip 502 is provided on the surface of the inner grip 501, and the interior of the inner grip 501 is hollow. A damper 503 is fixedly connected between the outer grip 502 and the inner grip 501 on opposite sides. The number of dampers 503 is set to multiple and evenly distributed in a ring. A shock-absorbing spring 504 is sleeved on the surface of the damper 503. The two ends of the shock-absorbing spring 504 are fixedly connected to the inner wall of the outer grip 502 and the surface of the inner grip 501, respectively.

[0029] In this embodiment: By setting the auxiliary grip component 5, the lawn mower will generate vibrations during operation. The vibrations will be transmitted from the connecting plate 401 to the inner grip 501. Then, the damping spring 504 will be quickly compressed, converting the mechanical energy brought by the vibration into elastic potential energy and storing it to buffer the initial strong vibration and achieve initial vibration reduction. During the process of the damping spring 504 rebounding to its original state, the damper 503 will gradually dissipate the excess energy when the damping spring 504 rebounds in the form of heat energy, so that the vibration will not bounce back and forth between the inner and outer grips 502, allowing the vibration energy to be reduced smoothly. The outer grip 502 is the part that the user directly holds. After the vibration is filtered layer by layer by the damping spring 504 and the damper 503, the vibration transmitted to the hand has been greatly reduced, so that when the user holds the outer grip 502, the impact on the hand is minimal, and a stable grip can be maintained, allowing the lawn mowing operation to be carried out accurately and smoothly, reducing hand fatigue caused by prolonged holding.

[0030] Specifically, such as Figure 2 , Figure 3As shown, a mounting block 402 is fixedly connected to the top of the connecting block 3. A mounting groove 403 is provided on the top of the mounting block 402. A bidirectional adjusting screw 404 is rotatably connected inside the mounting groove 403. Both sides of the surface of the bidirectional adjusting screw 404 are threadedly connected to mating blocks 405. A connecting plate 401 is fixedly connected to the top of the mating block 405.

[0031] Specifically, such as Figure 3 , Figure 5 As shown, guide grooves 6 are provided on the front and rear sides of the inner wall of the mounting groove 403. A sliding rod 7 is fixedly connected inside the guide groove 6. Guide blocks 8 are fixedly connected on the front and rear sides of the mating block 405. The guide blocks 8 are slidably connected to the surface of the guide groove 6.

[0032] Specifically, such as Figure 3 As shown, one end of the bidirectional adjusting screw 404 is fixedly connected to a rotating rod 9, and the rotating rod 9 passes through the mounting block 402 and is fixedly and rotatably connected to the mounting block 402.

[0033] In this embodiment: With the above settings, when the user needs to adjust the position of the auxiliary grip component 5, rotating the lever 9 can drive the bidirectional adjustment screw 404 to rotate. The rotation of the bidirectional adjustment screw 404 will drive the two mating blocks 405 to move horizontally in opposite directions. When the mating blocks 405 move, they will drive the connecting plate 401 to move together, so that the grip component on the top of the connecting plate 401 can move horizontally synchronously. During the process of the bidirectional adjustment screw 404 driving the mating blocks 405 to move, the guide block 8 will slide smoothly along the slide bar 7, thereby limiting the movement trajectory of the guide block 8 and the mating blocks 405, avoiding the mating blocks 405 from deviating during movement, improving the stability of the auxiliary grip component 5 position adjustment. Then, the user can flexibly change the lateral position of the auxiliary grip component 5 according to their own arm length and operating habits, find the most comfortable and convenient grip point, thereby improving the flexibility of use.

[0034] Specifically, such as Figure 1 , Figure 2 As shown, the connecting block 3 has an arc-shaped groove 10 inside, which is used in conjunction with the original handle 2.

[0035] Specifically, such as Figure 1 , Figure 2 As shown, the internal thread of the connecting block 3 is connected to a fixing screw 11, and the original handle 2 has a threaded groove inside that is used to cooperate with the fixing screw 11.

[0036] In this embodiment: By setting the arc groove 10, when installing the auxiliary grip component 5, the connecting block 3 is fitted onto the original handle 2. The arc groove 10 can fit tightly against the original handle 2, so that the two are initially positioned, preventing the connecting block 3 from rotating or sliding freely on the surface of the original handle 2, laying the foundation for subsequent fastening installation. By setting the threaded groove and fixing screw 11, after the connecting block 3 is fitted onto the original handle 2 and the arc groove 10 fits tightly, the fixing screw 11 is screwed in. The fixing screw 11 is continuously screwed in along the threaded groove. As the fixing screw 11 is tightened, it applies a continuously increasing compressive force to the inner wall of the original handle 2. With the help of the friction between the threads, the connecting block 3 can be firmly fixed to the surface of the original handle 2, improving the stability of the auxiliary grip component 5 when connected to the original handle 2.

[0037] Specifically, such as Figure 3 As shown, the outer grip 502 is made of a flexible material, and the surface of the outer grip 502 is engraved with anti-slip texture.

[0038] In this embodiment: Through the above settings, the flexible material outer grip 502 can better conform to the palm contour, adapt to the pressure applied by the hand, reduce the tension of the hand muscles, and the anti-slip texture can effectively increase the friction between the palm and the outer grip 502, ensuring that the user always maintains a stable and reliable grip and improving the safety of operation.

[0039] Working principle: First, align the arc-shaped groove 10 inside the connecting block 3 with the original handle 2 and insert it. Then, screw the fixing screw 11 into the threaded groove of the original handle 2. With the help of the friction between the threads, the connecting block 3 can be tightly fixed to the surface of the original handle 2. Then, when the lawn mower body 1 is working, it will generate vibration. The vibration will be transmitted to the connecting block 3 through the original handle 2. The connecting block 3 will then transmit it to the connecting plate 401 and the inner grip 501, and finally act on the auxiliary grip component 5. The vibration energy will compress the shock-absorbing spring 504, converting mechanical energy into elastic potential energy, reducing the initial vibration. Subsequently, the shock-absorbing spring 504... During rebound, the damper 503 suppresses and dissipates excess energy, preventing secondary vibration. After multiple layers of filtering, the vibration transmitted to the user's hand is greatly reduced. When the auxiliary grip position needs to be adjusted, rotating the lever 9 will drive the bidirectional adjusting screw 404 to rotate. When the bidirectional adjusting screw 404 rotates, it will drive the two mating blocks 405 to move horizontally in opposite directions along the mounting groove 403. When the mating blocks 405 move, they will drive the connecting plate 401 and the auxiliary grip component 5 to move synchronously. Then, the position of the auxiliary grip component 5 can be adjusted to a suitable position according to the user's needs.

[0040] 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.
