Curtain piece, electric roller shutter door and livestock and poultry draught fan of roller shutter door
The invention discloses a curtain piece, an electric roller shutter door and a livestock and poultry fan for the roller shutter door. The curtain piece comprises a locking unit arranged at the bottom end and an insertion buckle unit arranged at the top end, the insertion buckle unit is inserted into the locking unit of an adjacent curtain piece, and the insertion buckle unit can slide along the interior of the locking unit under the action of gravity to adjust the insertion depth. When the insertion buckle units are located at the deepest inserting positions, adjacent curtain pieces are mutually locked and cannot rotate relatively, and when the insertion buckle units are located at the shallowest inserting positions, the adjacent curtain pieces can rotate relatively. When a door is opened, due to the gravity effect, the distance between the adjacent curtain pieces is increased, a third hooking part of an inserting plate is inserted into a first hooking part, the curtain piece can rotate relatively at the moment, the curtain piece is locked when the door is opened and closed in a winding mode, the overall structural design is ingenious, the curtain piece can be wound when the door is opened while it is guaranteed that the door is closed and locked, and therefore, the strength of the roller shutter door is greatly improved when the door is closed, wind pressure can be borne, and sealing performance is guaranteed.
本发明公开一种帘片、电动卷帘门及卷帘门畜禽风机，帘片包括设在底端的锁口单元、设在顶端的插扣单元，插扣单元插入相邻帘片的锁口单元内，且插扣单元可在重力作用下沿所述锁口单元内部滑动以调节插入深度，所述插扣单元处于插入最深位置时，相邻所述帘片相互锁紧无法发生相对转动，所述插扣单元处于插入最浅位置时，相邻所述帘片可发生相对转动。本发明开门时，由于重力作用相邻帘片的间距拉大，插板的第三勾起部插入第一勾起部内，此时帘片能够相对转动，实现卷绕开门，关门时帘片锁紧，整体结构设计巧妙，在保证关门锁紧的同时，也能够实现开门时帘片的卷绕，从而大大提高关门时卷帘门强度，能够承受风压，并保证密封性能。
