Description

Technical Field

[0001] The present application relates to the technical field of agricultural harvesting machinery, and in particular to a handle flip locking mechanism of a lawn mower. Background Art

[0002] With the acceleration of urbanization, the demand for lawn maintenance in urban green spaces, home gardens, public parks and other places is increasing. Lawn mowers have become one of the main tools for maintaining lawns and are widely used for lawn mowing in various places. Efficient and convenient lawn mowers are an important demand of users, and new types of lawn mowers continue to appear on the market to meet different needs.

[0003] For example, publication number CN215379959U discloses a push rod folding mechanism and a lawn mower, which includes a chassis, a driving assembly and a push rod assembly installed on the chassis, and a limit assembly arranged on the push rod assembly. A limit plate is arranged on the push rod assembly, and a plurality of limit holes are opened on the limit plate. The positions of the limit holes can correspond to different working states of the lawn mower; the push rod assembly is fixed at the angle and position of the locking push rod assembly by cooperating with the limit holes through the spring pin on the limit assembly. When the push rod needs to be rotated, the spring pin is retracted into the push rod by pulling the cross bar, so that the push rod can rotate freely; when it is rotated to the required position, the cross bar is released, and the spring pin is automatically reset, so that the push rod assembly is fixed at the required position.

[0004] Although the limit assembly can control the angle and position of the push rod assembly to improve the portability and flexibility of the push mower, in actual operation, in order to ensure that the operator can easily pull the cross bar when standing on either side of the push mower, the cross bar is slid between the two push rods to make the cross bar protrude. Then, during the operation of the push mower, especially in dense grass or uneven terrain, the operator may accidentally touch the cross bar due to the protruding position of the cross bar, causing the limit assembly to fall off, causing the angle or position of the push rod to change unexpectedly, thereby affecting the stability and safety of the use of the push mower. Utility Model Content

[0005] In order to improve the problem in the related art that the cross bar is easily touched by the operator by mistake, causing the limit assembly to fall off, resulting in an unexpected change in the angle or position of the push rod, thereby affecting the stability and safety of the push mower, the present application provides a handle flip locking mechanism for a lawn mower.

[0006] The handle flip locking mechanism of a lawn mower provided in the present application adopts the following technical solution:
