COMPARTMENT AND BOTTOM DOOR THEREOF

摘要

Disclosed is a bottom door of a compartment, comprising a telescopic cylinder (2) and at least two sets of door bodies (1), wherein each set of door bodies (1) is provided with a set of transmission mechanisms, each transmission mechanism comprises a rotating shaft (3) and a transmission rod (4), and the rotating shaft (3) is connected to the door body (1) by means of the transmission rod (4), such that the door body (1) is driven to rotate when the rotating shaft (3) rotates; and the rotating shafts (3) are each driven by the telescopic cylinder (2) to rotate, and at least two rotating shafts (3) can be driven by the telescopic cylinder (2) successively to rotate, such that the door bodies (1) corresponding to the rotating shafts (2) are sequentially opened in a certain order. Compared with the prior art, the telescopic cylinder (2) only needs to always provide an acting force required for opening one set of door bodies (1), the required acting force is relatively small, the size of the telescopic cylinder (2) is reduced, the dead load is lowered, and the impacting force generated in the opening process is also reduced.
