Description

Automatic locking device for control rod of floor washing machine Technical Field The utility model relates to a floor washing machine device, in particular to an automatic locking device for a floor washing machine control rod. Background With the technical iteration of intelligent cleaning equipment, the floor cleaning machine gradually becomes a main stream product for replacing the traditional floor cleaning tool by virtue of the integrated design of rolling brush cleaning and dirt suction synchronization. The existing floor washing machine generally adopts a three-level mechanical structure of a floor washing main machine, a control rod and a holding handle, and the power transmission of the floor washing machine depends on that a user applies linear thrust to the main machine through the control rod and depends on a hinge mechanism to realize travel direction adjustment. The existing floor washing machine has the following defects that (1) a single-shaft hinging structure of a control rod and a host machine leads to a thrust direction to be strictly parallel to a travelling axis, actual measurement data show that when the deviation of a force application direction exceeds 5 degrees, transverse moment reaches 0.8-1.2 N.m, the probability of body deviation is raised to 67% or more, and (2) a force arm difference formed by a fulcrum of the control rod and the gravity center of the host machine leads to a user to continuously apply 12-15N thrust, and the gravity center distribution difference of a water purifying tank (usually positioned at the upper part of the control rod) and a sewage tank leads to wrist torque load exceeding 2.1 N.m/h, and (3) the hinging mechanism only provides unidirectional rotation freedom degree around a vertical shaft and cannot realize self-adaption of an inclined road surface or multi-dimensional steering in a narrow space.
