The lifting mechanism comprises a horizontal push rod, a swing rod, a rotating shaft, an eccentric wheel, a roller, a bearing seat, a lug seat, a movable platform and a fixed bottom plate, the rotating shaft is arranged on the fixed bottom plate through the bearing seat, the eccentric wheel is fixedly arranged on the rotating shaft, the upper end of the swing rod is also fixedly arranged on the rotating shaft, the rotating shaft is arranged on the fixed bottom plate in a rotating way, the lower end of the swing rod is hinged with the horizontal push rod, and the roller is arranged on the lower end face of the movable plate in a rotating way, is fixed on the movable plate through the lug seat, and is contacted with the eccentric wheel. When the horizontal push rod is moved right and left, the swing rod can drive the rotating shaft to swing right and left. Since the eccentric wheel is fixedly arranged on the rotating shaft, the eccentric wheel can swing correspondingly to drive the movable plate for back-and-forth lifting movement, and thus the requirements of lifting of the moving bracket relative to a fixed bracket can be satisfied.

The utility model content:
The purpose of this utility model is the elevating mechanism that a kind of silicon chip movable support bracket is provided for the efficient sintering furnace of no guipure.
The technical scheme that the utility model adopted is:
The elevating mechanism of described silicon chip movable support bracket, comprise horizontal push, fork, rotating shaft, bearing block, eccentric wheel, roller, ear seat, portable plate and fixed base plate, rotating shaft is installed on the fixed base plate by bearing block, eccentric wheel is fixedly mounted in the rotating shaft, the upper end of fork is fixedly mounted in the rotating shaft, and rotating shaft is installed in rotation on the fixed base plate, and the lower end and the horizontal push of fork are hinged, roller is fixed on by the ear seat on the lower surface of portable plate, and roller contacts with eccentric wheel.
