Description

Technical Field

[0001] This application relates to the field of lawn mower technology, and in particular to a multi-functional cordless lawn mower that integrates multiple operating modes. Background Technology

[0002] A lawn mower, also known as a lawn cutter, weed trimmer, or swivel mower, is an indispensable and efficient tool in modern garden maintenance and farmland management.

[0003] When clearing weeds, common lawnmowers require operators to adjust the cutting angle and change the normal operating posture when the weeds are located in hard-to-reach areas such as corners, around tree roots, near rocks, or on slopes. This increases the difficulty of operation, is not labor-saving, and the limited operation of lawnmowers makes it inconvenient for operators to clear weeds. Summary of the Invention

[0004] To facilitate weed removal by staff, this application provides a multi-functional cordless weed cutter that integrates multiple operation modes.

[0005] This application provides a multi-functional cordless lawn mower that integrates multiple operation modes, and adopts the following technical solution:

[0006] A multi-functional cordless lawn mower integrating multiple operation modes includes a lawn mower body and a handle, as well as an adjustment assembly connecting the lawn mower body and the handle. The adjustment assembly includes a steering seat, and the handle is slidably connected to the steering seat. The handle slides away from or towards the lawn mower body. A limit ring block is provided at one end of the handle near the steering seat. An arc groove is formed on the inner wall of the steering seat, and the arc groove extends along the circumferential inner wall of the steering seat.

[0007] The outer surface of the limiting ring block is provided with a protrusion, and the side wall of the arc groove is provided with a plurality of positioning grooves for the protrusion to be accommodated. The positioning grooves are in the same direction as the sliding of the handle in the steering seat. When the handle slides away from the main body of the lawn mower and the protrusion disengages from the positioning groove, the steering seat is rotated and the protrusion slides along the arc groove to another positioning groove. It also includes an anti-disengagement component to prevent the protrusion from disengaging from the positioning groove.

[0008] By adopting the above technical solution, when it is necessary to clear weeds in hard-to-reach areas such as corners, around tree roots, next to rocks, and slopes, and when the operator needs to adjust the cutting angle of the lawnmower, the handle is slid away from the main body of the lawnmower, and the protrusion disengages from the positioning groove. At this time, the steering seat is rotated, and the protrusion slides along the arc groove to another positioning groove. At this time, the cutting direction of the lawnmower changes. The operator can continuously adjust the cutting angle according to the position of the protrusion in different positioning grooves. The rotation angle is generally set to 0°, 90°, and 180°, so that the cutting surface corresponds to the horizontal plane facing down, 90 degrees to the left, and 90 degrees to the right, respectively, which facilitates the operation of the lawnmower and makes it easier for the operator to clear weeds.

[0009] Optionally, the anti-detachment component is a return spring, and a constriction ring is provided at the end of the steering seat away from the main body of the grass cutter. One end of the return spring is provided on the limiting ring block, and the other end is provided on the constriction ring. The spring force direction of the return spring is the same as the sliding direction of the handle, and the return spring drives the protrusion to be located in the positioning groove.

[0010] Optionally, a limiting block is provided at the end of the limiting ring block away from the handle, and a plurality of receiving grooves are provided in the steering seat for the limiting block to be accommodated. When the protrusion is located in the positioning groove, the limiting block is also located in the receiving groove.

[0011] By adopting the above technical solution, the positioning of the limiting ring block is facilitated by the limiting block and the receiving groove.

[0012] By adopting the above technical solution, the return spring is used to drive the protrusion into the positioning groove, prevent the protrusion from disengaging from the positioning groove, and improve the connection stability of the handle.

[0013] Optionally, the adjustment component also includes a button. The main body of the lawn mower has a through groove for the button to slide. The button slides along the through groove away from or near the steering seat. Both the steering seat and the main body of the lawn mower have several toothed grooves. The side wall of the button is circumferentially provided with several toothed blocks that match the toothed grooves. The toothed blocks mesh in the toothed grooves.

[0014] A sliding spring is provided at the end of the button near the steering position. The direction of the spring force is the same as the direction of the button's sliding movement. The sliding spring drives the button to slide away from the steering seat. The toothed blocks are all engaged with the toothed grooves in the steering seat and the main body of the lawnmower. The rotation of the steering seat is limited. When the button slides closer to the steering seat, the toothed blocks disengage from the toothed grooves of the steering seat, and the steering seat rotates to adjust the angle of the handle.

[0015] By adopting the above technical solution, when the two buttons slide towards the steering seat along the through groove at the same time, and the toothed blocks on the buttons are completely disengaged from the toothed blocks on the main body of the lawnmower, the steering seat can rotate. The rotation of the steering seat drives the buttons to rotate at the same time, thereby realizing the adjustment of the handle angle.

[0016] Optionally, the handle includes a first connecting rod, a sleeve block, and a second connecting rod disposed on the first connecting rod. The first connecting rod is slidably disposed on the steering seat. The limiting ring block is disposed at the end of the first connecting rod. It also includes a handle with a sliding groove. The second connecting rod is slidably disposed in the sliding groove. The handle has a threaded line near the opening of the sliding groove for threaded connection to the inner wall of the sleeve block. The sleeve block is threaded to the handle. Several clamping blocks are arranged circumferentially at the opening of the sliding groove. The sleeve block is narrowed towards the end near the steering seat. When the sleeve block is tightened towards the handle, the sleeve block drives the clamping blocks to press against the surface of the second connecting rod to fix the second connecting rod and the handle.

[0017] By adopting the above technical solution, when it is necessary to extend the length of the handle, the sleeve block is loosened, the clamping block is no longer pressed against the surface of the connecting rod two, and the connecting rod two slides away from the handle. After sliding to a suitable distance, the sleeve block is tightened again, making it convenient to adjust the length of the handle.

[0018] Optionally, the connecting rod 2 is equipped with a power source, and the handle is equipped with a control switch. The control switch is electrically connected to the power source, and the power source is electrically connected to the main body of the lawn mower through a circuit.

[0019] By adopting the above technical solution, the operation of the main body of the lawn mower is controlled by the control switch on the connecting rod 2.

[0020] Optionally, it also includes a roller seat and two rollers. The two rollers are rotatably connected to both sides of the roller seat via a rotating shaft. The bottom and side walls of the lawn mower body are provided with locking blocks. The roller seat has an insertion slot for the locking blocks to be inserted into. The roller seat has an elastic buckle and a deformation cavity for the elastic buckle. An abutment block is provided at the end of the elastic buckle away from the deformation cavity. The locking block has a slot. When the locking block is inserted into the insertion slot, the elastic buckle is abutted by the outer wall of the locking block and deforms away from the lawn mower body. When the locking block is fully inserted into the insertion slot, the abutment block returns to its original position and abuts against the slot. The abutment block limits the locking block in the insertion slot.

[0021] By adopting the above technical solution, when the roller seat needs to be installed, the insertion slot is inserted into the locking block, and the elastic buckle abuts against the locking block to generate deformation. When the side wall of the abutting block is locked into the slot, the roller seat is installed. The roller seat is installed by the elastic buckle and the abutting block, which makes the roller seat easy to install and easy to disassemble.

[0022] Optionally, the main body and side wall of the grass cutter are provided with mounting blocks, the locking block is set on the mounting block, the outer diameter of the locking block is larger than the outer diameter of the mounting block, the roller seat is inserted into the opposite sides of the locking block, and the locking block has two adjacent slots in the circumferential direction, both of which are for the roller seat to be engaged, and the slots are perpendicular to each other.

[0023] By adopting the above technical solution, the roller seat has two installation directions through two adjacent slots, and can be installed onto the card block in both directions.

[0024] Optionally, the roller seat has a limiting groove for the rotating shaft to slide. The roller slides away from or near the bottom of the grass cutter body along the length of the limiting groove. The side wall of the limiting groove has several adjusting grooves for the rotating shaft to be accommodated. It also includes an adjusting spring. The two ends of the adjusting spring are respectively connected to the roller seat and the rotating shaft. The adjusting spring drives the rotating shaft to be located in the adjusting groove.

[0025] By adopting the above technical solution, when the height of the roller needs to be adjusted, the height of the roller can be easily adjusted through the adjustment groove and the adjustment spring.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When it is necessary to adjust the cutting angle of the lawnmower to clear weeds in areas that are difficult to clear, slide the handle away from the main body of the lawnmower so that the protrusion slides along the arc groove into another positioning groove. At this time, the cutting direction of the lawnmower changes. The operator can continuously adjust the cutting angle according to the position of the protrusion in different positioning grooves, which facilitates the operation of the lawnmower and makes it easier for the operator to clear weeds.

[0028] 2. Press both buttons simultaneously to completely disengage the toothed blocks on the buttons from the toothed blocks on the main body of the lawn mower, allowing the steering seat to rotate and adjust the angle of the handle.

The adjusting spring 93 drives the rotating shaft 94 to be located in the adjusting groove 92.

[0048] The implementation principle of this application's embodiment of a multi-functional cordless lawnmower integrating multiple operation modes is as follows: When weeding is required, the operator adjusts the length of the handle 2 by sliding the connecting rod 23 through the sleeve 22 according to their own height and weeding distance. When it is necessary to clear weeds in hard-to-reach areas such as corners, around tree roots, near rocks, and slopes, and the operator needs to adjust the cutting angle of the lawnmower, they hold the connecting rod 21 and slide the connecting rod 21 away from the lawnmower body 1, causing the protrusion 43 to disengage from the positioning groove 44. Rotate the steering seat 31, and the protrusion 43 slides along the arc groove 42 into another positioning groove 44. At this time, the cutting direction of the grass cutter changes. The operator can continuously adjust the cutting angle according to the position of the protrusion 43 in different positioning grooves 44. The rotation angle of the grass cutter body 1 is generally set to 0°, 90°, and 180°, so that the grass cutting surface corresponds to the horizontal plane facing down, 90 degrees to the left, and 90 degrees to the right, respectively. The operator can adjust the cutting angle according to the needs of use, which facilitates the grass cutter's grass removal operation and makes it easier for the operator to clean up weeds in areas that are difficult to clean.
