Scissor type door
The invention relates to a scissor type door. The scissor type door comprises a rack, a power device, a crank, a first connecting rod, a main rocker arm, an auxiliary rocker arm, a sector-shaped door body and an inner door body. The sector-shaped door body is fixedly arranged on the auxiliary rocker arm so that the sector-shaped door body and the auxiliary rocker arm can jointly swing. The sector-shaped door body is hollow and is provided with a lateral opening. The inner door body is connected with the auxiliary rocker arm through a connecting rod mechanism arranged on the rack. When the auxiliary rocker arm swings around a rotating shaft, the auxiliary rocker arm drives the inner door body through the connecting rod mechanism to stretch out from or draw back into the lateral opening of the sector-shaped door body so that the sector-shaped door body and the inner door body can be switched between the stopping state and the releasing state. According to the scissor type door, the inner door body is driven by the connecting rod mechanism to stretch out or draw back; and compared with a sliding mechanism and a gear mechanism, the scissor type door has the beneficial effects of being low in friction and free of influences of foreign matter.
