DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-5 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0030] The embodiment of the present application discloses a lawn mower operating armrest assembly structure.

[0031] Reference Figure 1 and Figure 2 A lawn mower operating armrest assembly structure of the present embodiment includes a chassis 1 and an armrest assembly 2, the armrest assembly 2 includes an upper armrest 21 and a lower armrest 27, the upper armrest 21 is fixedly connected to the chassis 1, and the lower armrest 27 is installed on the upper armrest 21, the upper armrest 21 includes two connecting tubes 22, a hand handle 23 and a limiter 25, the two connecting tubes 22 are respectively fixedly connected to the lower armrest 27, and the hand handle 23 is fixedly connected to two sliding tubes 24, the two sliding tubes 24 correspond to the two connecting tubes 22 respectively, one end of the two sliding tubes 24 is respectively slidably connected to the corresponding connecting tube 22 along the axial direction of the connecting tube 22, and the limiter 25 is used to limit the sliding of the sliding tube 24.

[0032] Reference Figure 1 and Figure 2 , pull the hand-held part to make the two sliding tubes 24 slide in the connecting tube 22 at the same time, and adjust the height of the armrest part of the lawn mower by changing the contact area between the sliding tube 24 and the connecting tube 22, and limit the sliding of the sliding rod by the limiting member 25, so as to lock the position of the sliding tube 24 on the connecting tube 22.

[0033] Reference Figure 1-Figure 3The limiting member 25 includes an abutment block 251 and a driving assembly 26. The abutment block 251 is rotatably connected to the connecting tube 22. A clamping block 252 is provided on the abutment block 251. A plurality of clamping grooves 221 that can be matched with the clamping block 252 are provided on the inner wall of the connecting tube 22. The plurality of clamping grooves 221 are evenly distributed along the axial direction of the connecting tube 22. The driving assembly 26 is used to drive the rotation of the abutment block 251. When the abutment block 251 rotates toward the clamping groove 221 to the extreme position, the clamping block 252 is matched with any clamping groove 221. When the driving assembly 26 drives the abutment block 251 to rotate toward the clamping groove 221 to match with any clamping groove 221, the position of the sliding tube 24 on the connecting tube 22 is limited.

[0034] Reference Figure 1-Figure 4 The driving assembly 26 includes a conical block 261, a connecting rod 262 and a force block 263. The conical block 261 is slidably connected in the sliding tube 24. The conical block 261 is tapered from one end close to the hand-held handle 23 to the other end away from the hand-held handle 23. A hinged rod 253 is hingedly connected to the abutment block 251. The end of the hinged rod 253 away from the abutment block 251 is slidably connected to the conical block 261 along the circumferential outer surface of the conical block 261. The force block 263 is penetrated along the sliding direction of the conical block 261 and slidably connected to the hand-held handle 23. The two ends of the connecting rod 262 are respectively fixedly connected to the conical block 261 and the force block 263.

[0035] Reference Figure 2-Figure 4 , the force block 263 is forced to move, and through the connection of the connecting rod 262, the conical block 261 and the connecting rod 262 are moved in the same direction together, and the hinge rod 253 is caused to slide along the surface of the conical block 261; in the process that one end of the hinge rod 253 slides from the end of the conical block 261 with a larger axial cross-section to the end of the conical conical block 261 with a smaller axial cross-section, the hinge rod 253 drives the abutment block 251 to slide toward one side of the conical block 261, so that the clamping block 252 is separated from the clamping groove 221 and contacts the limit of the sliding tube 24 on the connecting tube 22; when one end of the hinge rod 253 slides from the end of the conical block 261 with a smaller axial cross-section to the end of the conical block 261 with a larger axial cross-section, the hinge rod 253 drives the abutment block 251 to slide toward one side of the clamping groove 221, so that the clamping block 252 is clamped and matched with the clamping groove 221, thereby locking the position of the sliding tube 24 on the connecting tube 22.

[0036] Reference Figure 2-Figure 4The driving assembly 26 also includes a first spring 264 and a second spring 265. The first spring 264 is located in the handle 23. The two ends of the first spring 264 respectively abut against the force block 263 and the inner wall of the handle 23. The first spring 264 always drives the force block 263 to move toward the side away from the central axis of the handle 23. The second spring 265 is located in the sliding tube 24, and a baffle 241 is coaxially and fixedly connected inside the sliding tube 24. The two ends of the second spring 265 are respectively abutted on the baffle 241 and the conical block 261, and the second spring 265 always drives the conical block 261 to slide toward the side away from the hand-held handle 23; when no force is applied to the force block 263, the first spring 264 drives the force block 263 to slide toward the side away from the central axis of the hand-held handle 23, and the second spring 265 always drives the conical block 261 to slide toward the side away from the hand-held handle 23, so that the hinge rod 253 always slides toward the end of the conical block 261 with a larger axial cross-section, thereby locking the position of the sliding tube 24 on the connecting tube 22, reducing the possibility of sliding of the sliding tube 24 when no force is applied to the force block 263.

[0037] Reference Figure 1 and Figure 5 The handle 23 is covered with a rubber sheath 231. The rubber sheath 231 can increase the friction when the hand is held on the handle 23, and reduce the possibility of the operator's hand slipping on the handle 23 when pushing the lawn mower. The rubber sheath 231 is provided with a matching groove 2311 that can match with the force block 263. When the rubber sheath 231 is covered on the handle 23, the force block 263 matches with the matching groove 2311. The matching groove 2311 can reduce the possibility that the operator's fingers are pinched by the gap between the force block 263 and the handle 23 when applying force to the force block 263, and reduce the possibility of safety hazards during use.

[0038] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
