Embodiment Construction

[0036] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] In order to achieve the purpose of the present invention, in some embodiments of the lifting structure of the wheel axle assembly,

[0038] Such as Figure 1-8 As shown, the lifting structure of the wheel shaft assembly is arranged on the vacuum cleaner housing 4, and includes: a knob 1, a cam 2 and a wheel shaft assembly 3. The knob 1 is connected to the rotating part 21 of the cam 2, and the end of the cam 2 is provided with a plurality of continuous With the uneven positioning groove 22, the wheel and axle assembly 3 is in contact with the end of the cam 2. The knob 1 is provided with a groove 11, and the knob portion of the cam 2 is provided with a protrusion 23 matching the groove 11.

[0039] The adjacent positioning grooves 22 are smoothly transitioned and connected in a circular arc. The inner wall of the positioning groove 22 is...

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 axle assembly applied to a vacuum cleaner. Background technique [0002] With the increase in productivity, vacuum cleaners have gradually become a necessity in the lives of contemporary people. 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 used on carpets of different occasions and materials, the manufacturer adopts the adjustment of the height of the axle assembly from the ground. However, the lifting structure of the wheel axle assembly of the traditional vacuum cleaner is realized by using multiple parts, which has a complicated structure, high production cost, and high maintenance cost. [0003] Therefore, a lifting structure of the wheel axle assembly that can effectively adjust the height of the wheel axle assembly from the gr...
