Electric lawn mower with functions of adjusting height and secondarily folding

Abstract

The invention discloses an electric lawn mower with the functions of adjusting height and secondarily folding, including a machine body, and a secondarily folding push hand rotatablely connected to the rear end of the machine body, wherein the machine body includes a shell, front wheels and back wheels respectively used for supporting the front and rear ends of the shell, a height-adjusting mechanism is arranged in the shell for adjusting the height of the machine body relative to ground, the secondarily folding push hand includes a gesture-locking mechanism fixedly connected with the rear endof the shell, a lower push rod with a root part connected with the gesture-locking mechanism, an upper push rod arranged on the top of the lower push rod, and a cross rod arranged between the upper push rod and the lower push rod, and when the upper push rod carries out reciprocating rotation action relative to the lower push rod and around the cross rod, the bottom of the upper push rod and thetop of the lower push rod are selectively clamped. The electric lawn mower disclosed by the invention is convenient to store by secondarily folding, and also can adjust the height of the machine bodyfrom the ground to adapt to different operational requirements.

Description

technical field [0001] The invention relates to the field of electric garden tools, in particular to an electric lawnmower that can be adjusted in height and can be folded twice. Background technique [0002] On garden tools such as hand-push electric lawn mowers or hand-push electric sweepers, it is often necessary to use a push handle for controlling the driving or forward direction of the garden tool. The push handle is generally composed of an upper push rod and a lower push rod. The connection of the traditional up and down push rods is relatively independent. At least two actions are required to realize the connection assembly and posture adjustment of the up and down push rods. It is cumbersome to use, and it is not easy to unfold and store. With the ability to adjust the angle between the push handle and the garden tool in real time and conveniently to adapt to the height of the user, the existing push hands still have the following problems: First, the reliability o...

[0002] On garden tools such as hand-push electric lawn mowers or hand-push electric sweepers, it is often necessary to use a push handle for controlling the driving or forward direction of the garden tool. The push handle is generally composed of an upper push rod and a lower push rod. The connection of the traditional up and down push rods is relatively independent. At least two actions are required to realize the connection assembly and posture adjustment of the up and down push rods. It is cumbersome to use, and it is not easy to unfold and store. With the ability to adjust the angle between the push handle and the garden tool in real time and conveniently to adapt to the height of the user, the existing push hands still have the following problems: First, the reliability of posture locking is poor, and the user uses it after locking a posture At the same time, the posture lock is often unstable; among them, the operation of unlocking the posture and adjusting the posture back and forth is more complicated, and at the same time, it is easy to cause the mechanism to get stuck in the process of adjusting the posture; again, the structure is complicated, and it is not easy to assemble and overhaul.

[0003] In addition, garden tools often require a push handle to control the driving or forward direction of the garden tool. The push handle is generally composed of an upper push rod and a lower push rod. The traditional connection of the upper and lower push rods is relatively independent and requires at least two actions to achieve The connection assembly and posture adjustment of the upper and lower push rods are cumbersome to use, and it is not easy to unfold and store, and the appearance is abrupt and unnatural. In addition, the garden tool needs to be able to adjust the angle between the push handle and the garden tool in real time and conveniently, so as to To adapt to the height of the user, the existing push hands still have the following problems: first, the reliability of the posture locking is poor, and when the user uses it after locking a posture, the phenomenon of posture locking often appears unstable; wherein, the unlocking of the posture and The operation of adjusting the attitude back and forth is more complicated, and at the same time, it is easy to cause the mechanism to get stuck in the process of adjusting the attitude; again, the structure is complicated and it is not easy to assemble and overhaul
