Description

Technical Field

[0001] This utility model relates to the field of lawn mower technology, and more specifically, to a lawn mower handle structure and a lawn mower having the structure. Background Technology

[0002] Handheld cutting machines use various cutting blades as their tools. These blades are sometimes made of resin. However, because resin-made plate-shaped blades wear down when cutting lawn grass, weeds, and other vegetation, they need to be replaced as needed based on their wear condition.

[0003] However, when using such handheld cutting machines to cut lawn grass, weeds, etc., it is usually done outdoors. At this time, the operator needs to carry a replacement cutting blade with him, which is quite troublesome.

[0004] Currently, many handheld cutting machines on the market have various blade storage structures. For example, CN217064599U uses a movable storage box on the lawnmower to store the blades. However, this adds extra parts or accessory compartments for blade storage, increasing product cost and user complexity. CN209057529U's brush cutter uses a storage section on the rear housing in front of the battery pack, but changing the blades requires removing the battery pack, increasing the hassle. Furthermore, the added parts or accessories are at risk of becoming loose or lost during machine use, making these designs unsuitable from both a cost control and ease-of-use perspective.

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings: like Figure 1As shown, a lawnmower handle structure with a blade storage structure includes: a right handle housing 101 and a left handle housing 102. The right handle housing 101 and the left handle housing 102 are fastened together to form a grip portion 100. The grip portion 100 includes a handle portion 110 and a connecting portion 120. A trigger 111 is provided on the handle portion 110. A cutout 112 is provided between the handle portion 110 and the connecting portion 120. A cutting blade positioning post 130 is provided below the connecting portion 120. The front of the 20 is provided with a foot 140, which is used to connect with the battery pack 200. The rear side of the foot 140 is provided with a cutting knife storage compartment 150, which has an opening 151. The cutting knife positioning post 130 and the cutting knife storage compartment 150 are spaced apart. The structure is simple. It only requires forming the cutting knife positioning post 130 in the right shell 101 and the left shell 102 of the handle, and hollowing out the foot 140 to form the cutting knife storage compartment 150.

[0025] Furthermore, the cutting blade positioning post 130 extends downward perpendicular to the connecting part 120, and the opening 151 faces rearward.

[0026] To prevent the cutting blade 210 from becoming contaminated and to further improve its tightness, a rubber strip 152 is provided at the opening 151 to seal the cutting blade storage compartment 150. The rubber strip 152 may have a window, which, through the friction of the rubber strip 152, can restrict further movement of the cutting blade 210 and prevent it from falling off when the handle 110 vibrates.

[0027] Furthermore, the cutting blade positioning post 130 and the cutting blade storage compartment 150 are located on the same horizontal plane.

[0028] Furthermore, the cutting blade storage compartment 150 includes an upper surface 153, a lower surface 154, and a side surface 155. The upper surface 153, the lower surface 154, and the side surface 155 form a receiving space with an opening 151. The receiving space is used to receive part of the cutting blade 210. The upper surface 153 and the lower side of the connecting part 120 are located on the same horizontal plane.

[0029] like Figure 2 As shown, to prevent axial movement of the cutting blade 210 after installation and ensure precise positioning, the stepped design of the cutting blade positioning post 130 forms a limiting step. The cutting blade positioning post 130 includes a first end 131, a second end 132, and a stop 133. The first end 131 is a free end, the stop 133 is connected to the connecting part 120, and the second end 132 is located between the stop 133 and the first end 131. The diameter of the first end 131 is larger than the diameter of the second end 132, and the thickness of the first end 131 is smaller than the thickness of the second end 132. The second end 132 is used to position the cutting blade 210. Figure 3As shown, the first end 131 is used to fit the cutting blade 210, and the second end 132 is used to install multiple cutting blades 210.

[0030] To prevent accidental injury to users from the blades during transportation or storage, the spacing between the blades should be less than the length of the cutting blade 210. Preferably, one-quarter to one-eighth of the overall length of the cutting blade 210 is stored in the cutting blade storage compartment 150.

[0031] like Figure 1 As shown, a lawn mower with the aforementioned handle structure includes a right handle housing 101, a left handle housing 102, a support rod 220, a front housing 230, a motor 240, a cutting blade 210, and a battery pack 200. The right housing 101 and the left housing 102 of the grip handle are fastened together and located at the rear end of the support rod 220. The front housing 230 is connected to the front end of the support rod 220; Motor 240 is fixed inside the front housing 230 and is used to drive the cutting blade 210 to rotate. A battery pack 200, which is detachably mounted on the extended leg 140, is used to provide a power source to the motor 240; The rear end of the cutting blade 210 is fitted onto the cutting blade positioning post 130, and the front end of the cutting blade 210 is housed in the cutting blade storage compartment 150.

[0032] like Figure 5 As shown, the cutting blade 210 has an end face 211 and a cutting edge 212, with the cutting edge 212 extending along the length of the end face 211. The end face 211 has a first mounting portion 213 and a second mounting portion 214. The first mounting portion 213 is a first mounting hole with a first diameter, and the second mounting portion 214 is a second mounting hole with a second diameter. The first diameter is larger than the second diameter. The first mounting portion 213 and the second mounting portion 214 are connected by an intermediate section 215. The diameter of the cutting blade positioning post 130 is smaller than the first and second diameters, and the diameter of the cutting blade positioning post 130 is larger than the width of the intermediate section 215.

[0033] Furthermore, when storing the cutting blade 210, the first mounting part 213 of the cutting blade 210 is aligned and passes through the first end 131. When the end face 211 of the cutting blade 210 is pressed against the stop part 133, the cutting blade 210 is pushed towards the storage compartment so that the second end 132 enters the second mounting part 214 and the middle section 215 passes through the cutting blade positioning post 130. At this time, the cutting blade 210 will be unable to be pushed further.

[0034] The operating principle of this utility model is: like Figure 6As shown, when storing the cutting blade 210, the first mounting portion 213 of the cutting blade 210 is aligned and passed through the first end portion 131. When the end face 211 of the cutting blade 210 is pressed against the stop portion 133, the cutting blade 210 is pushed towards the storage compartment so that the second end portion 132 enters the second mounting portion 214. At this point, the cutting blade 210 can no longer be pushed, making installation convenient and reliable. At this time, the blade surface 212 of the cutting blade 210 is partially or completely stored in the cutting blade storage compartment 150 formed by the right housing 101 and the left housing 102 of the handle. The cutting blade storage compartment 150 is located above and behind the battery pack 200, and does not obstruct the installation and removal of the battery pack 200.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
