Abstract

The invention discloses a wheel axle assembly lifting structure arranged on a dust collector shell. The wheel axle assembly lifting structure comprises a rotary knob, a cam and a wheel axle assembly. The rotary knob is in matched connection with a rotary portion of the cam. The end of the cam is provided with a plurality of continuous uneven positioning grooves. The wheel axle assembly is in contact connection with the end of the cam. The wheel axle assembly lifting structure is simple in structure, convenient and fast to operate, low in cost and capable of effectively adjusting the terrain clearance of the wheel axle assembly.

Description

technical field [0001] The invention relates to a vacuum cleaner technology, in particular to a lifting structure of a wheel shaft assembly applied to a vacuum cleaner. Background technique [0002] With the improvement of productivity level, vacuum cleaners have gradually become a necessity of contemporary people's life. How to optimize the performance of vacuum cleaners has become a problem that manufacturers have been thinking about. In order to allow the vacuum cleaner to be effectively applied to different occasions and carpets of different materials, the manufacturer realizes this by adjusting the height of the wheel shaft assembly from the ground. However, the lifting structure of the axle assembly of the traditional vacuum cleaner is realized by multiple parts, which has a complicated structure, high production cost and high maintenance cost. [0003] Therefore, there is an urgent need to propose a wheel axle assembly lifting structure that has a simple structure a...
