One waves knuckle arm head
Technical field
The utility model belongs to window cleaning equipment assembly, and particularly one waves knuckle arm head.
Background technology
Existing window cleaning equipment knuckle arm head is generally fixed, only can turn round, and without swing function, makes the operating efficiency of wiping window limited.
Summary of the invention
The purpose of this utility model is that design one waves knuckle arm head.
To be solved in the utility model is that existing window cleaning equipment knuckle arm head is generally fixed, only can turn round, and without swing function, makes the problem that the operating efficiency of wiping window is limited.
For realizing the purpose of this utility model, this has the technical scheme of employing to be: one waves knuckle arm head, comprise pivoting support, described pivoting support is provided with revolution underframe, swiveling gear and turning motor, described swiveling gear is connected with turning motor, it is characterized in that described revolution underframe front end is provided with the first Swing Arm, second Swing Arm, first gear and the second gear, the first Swing Arm tail end is located at by the first described gear, the second Swing Arm tail end is located at by the second described gear, the first described gear and the second gear engage each other, the arm of the first described Swing Arm is connected with electric pushrod with it, the other end of described electric pushrod is connected to it the frame of revolution underframe.
The first described Swing Arm and the loose joint of the second Swing Arm difference are in the front end of revolution underframe.The arm head place of the first described Swing Arm is provided with the first head pulley, and arm tail place is provided with the first horizontal trolley; The arm head place of the second described Swing Arm is provided with the second head pulley, and arm tail place is provided with the second horizontal trolley; The first described horizontal trolley is located at the first gear bottom, and the second described horizontal trolley is located at the second gear bottom.The rear portion of described revolution underframe is provided with vertical sliding wheel.
The utility model has the advantages that: the utility model not only has the revolute function of existing knuckle arm head, also has swing function simultaneously; Wave arm head to swing around pivoting support, make to be suspended on knuckle arm head platform can pivotal while, certain luffing motion can be done; The utility model also by the structure of many group pulleys, enable flexible steel wire turn round through knuckle arm and rocking action time, kink phenomenon can not be there is.The utility model adopts electric pushrod as the power waved, and the motion controlling Swing Arm is more effective.The synchronization action that the engagement realization that the utility model passes through the first gear and the second gear swings the first Swing Arm and the first Swing Arm.
