Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, it is provided that the reciprocal wiping arrangement in a kind of blackboard for education plate face.
The technical solution of the utility model realizes in the following manner, and this reciprocal wiping arrangement in blackboard for education plate face, its structure includes blackboard, horizontal frame and mill teeth bar；
The horizontal frame of blackboard is provided with mill teeth bar, the mill teeth limit of mill teeth bar towards blackboard panel front,
Transition gear engages with mill teeth bar, and wiper rolls gear engages with transition gear；
Transition gear, wiper rolls gear are co-located on same wheel carrier,
Wheel carrier is perpendicular to mill teeth bar and arranges, and the rear end of wheel carrier extends backwards over mill teeth bar and is provided with apparatus for suspension, and the two ends of apparatus for suspension are respectively arranged with orientation road wheel forward,
Orientation road wheel is provided with race, and wheel slot fit is on the guide rail of the bar back of the body of mill teeth bar, and apparatus for suspension is connected realization and mill teeth bar relative lateral motion by orienting road wheel with the rolling of guide rail；
Wiper rolls gear is fixedly installed on longitudinal wiper rolls, and the roll surface of longitudinal wiper rolls is provided with roll surface bristle, roll surface bristle and blackboard panel pressure contact；
Wheel carrier is fixedly installed and longitudinally surrounds cover, and longitudinal opening of cover that surrounds, towards blackboard panel, longitudinally surrounds the horizontal both sides of cover and is respectively arranged with the dust-proof bristle of side, the dust-proof bristle of side and blackboard panel pressure contact；
Wheel carrier extends to blackboard panel front and crosses and longitudinally surrounds cover and extended have push handle.
Longitudinally surround and be provided with dust cavity between cover inwall and longitudinal wiper rolls roll surface bristle.
Longitudinally longitudinal top and longitudinal bottom of encirclement cover is respectively arranged with end cap, removably connects between end cap and longitudinally encirclement cover.
This utility model compared with prior art produced by provide the benefit that:
The reciprocal wiping arrangement in this blackboard for education plate face utilizes orientation walking mechanism to realize longitudinal wiper rolls, when laterally walking, blackboard be can be carried out wiping, it is only necessary to can realize the wiping to blackboard by hands reciprocal laterally push-and-pull push handle gently.Mill teeth bar, transition gear, the setting of wiper rolls gear make to form differences in motion between roll surface and the blackboard panel of longitudinal wiper rolls, it is achieved the friction to blackboard panel of the roll surface bristle, play the effect of blackboard wiping chalk writings, simple and convenient, effective and rapid, time saving and energy saving.
This reciprocal wiping arrangement in blackboard for education plate face is reasonable in design, simple in construction, safe and reliable, easy to use, be easily maintained, have good value for applications.
