Abstract

The invention discloses an opening and closing device for a transmission passageway. The opening and closing device comprises a base part, a pendant fitting, at least one beam body and at least one pair of vertical arms. The base part is provided with at least one driving unit. The pendant fitting is arranged above the base part. The beam body has two ends and a central position positioned between the two ends. The central position of the beam body is pivoted to the pendant fitting. One projection between the two ends of the beam body has a driven piece. The driving unit drives the driven piece to swing with the central position of the beam body as an axis. One end of each of the two vertical arms can be movably connected at two opposite positions of the beam body with the central position as the center, and the other end of each of the two vertical arms is provided with a cover body.

Description

technical field [0001] The invention relates to an opening and closing device, in particular to an opening and closing device for a transmission entrance which can control the opening or closing of the transmission entrance. Background technique [0002] For transmission inlets and outlets such as dampers or valves, when it is desired to open or close these transmission inlets and outlets, it is necessary to use an opening and closing device. [0003] see figure 1 The known opening and closing device shown includes a base body 1, two drive elements 11 arranged on the base body 1, two transmission inlets 12 opened on the base body 1, and the two drive elements 11. The two cover bodies 112 are driven to move up and down, and the two cover bodies 112 respectively correspond to the two transmission inlets 12 on the base body 1 . [0004] Therefore, when wanting to figure 1 When the transmission entrance 12 on the left is opened and the transmission entrance 12 on the right is...
