Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is part of the embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belong to the model of the utility model protection
Enclose.
Reference picture 1, one kind ventilation cabinet door automatic sensing lowering or hoisting gear, including frame 1, and it is arranged on the front of frame 1
Cabinet door 2, the restocking of frame 1 of the top of cabinet door 2 are provided with a universal driving shaft 3, and the left and right ends of the universal driving shaft 3 are arranged with a company
Gear 4 is connect, a chain 5 is arranged with the connection gear 4, a drive gear 7 is also arranged with the universal driving shaft 3, it is described
Drive gear 7 is connected with a motor 8 by drive belt 9, and motion sensor 10, the action are provided with the frame 1
Inductor 10 is electrically connected with a control centre 11, and the control centre 11 controls the start and stop of motor 8.
Motion sensor 10 can sense the motion of experimenter, when experimenter acts signal opening or shuts cabinet
Signal is passed to control centre 11 by Men Shi, motion sensor 10, and control centre 11 controls motor 8 to drive chain 5 to roll
Or put down, drive the cabinet door 2 of the one end of chain 5 to move or move downward upwards, realize the automatic lifting of cabinet door 2, it is not necessary to
