Detailed Description
The following description will explain embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1, which is a top view of the present invention, the present invention relates to a ventilating sight-blocking door curtain, which comprises two rows of door curtains, each row of door curtains comprises a plurality of door curtain strips, hooks, door curtain strip hanging rods, gear rotating shafts, a transmission device and a door curtain transverse hanging rod, the number of the door curtain strips is the same as the number of the door curtain strip hanging rods and the number of the gear rotating shafts, wherein the transmission device is arranged in the door curtain horizontal hanging rod, the door curtain strip is hung on the door curtain strip hanging rod through the hook, one end of the gear rotating shaft is arranged in the door curtain horizontal hanging rod, and is connected with a transmission device, the other end is connected with a door curtain strip hanging rod, all door curtain strips can synchronously rotate with the door curtain strip hanging rod through the transmission device by the same angle by taking respective gear rotating shafts as axes, two rows of door curtains are arranged between the door frames in a staggered way, the horizontal hanging rods of the two rows of door curtains are parallel to each other, and the rotation directions of the door curtain strips of the two rows of door curtains are opposite. Therefore, the two functions of ventilation and sight blocking can be well coordinated, the sight can be blocked while the ventilation effect is achieved, the privacy is guaranteed, and the two rows of door curtains are completely closed into two closed door curtains, so that cold wind can be effectively blocked.
As an optimized structure of the invention: in the two rows of door curtains, the door curtain strips at two ends of one row of door curtains are half-width door curtain strips.
As shown in fig. 2, a structural section view of the transmission device of the present invention and fig. 3, a side view of the present invention, as an optimized structure of the present invention: the transmission device comprises a rotating handle, a gear and a rack, wherein the rack is arranged in the door curtain transverse hanging rod and is tightly meshed with one end of a gear rotating shaft, the rotating handle is arranged at one end of the door curtain transverse hanging rod and is fixedly connected with the gear, and the gear is tightly meshed with the rack.
When the door curtain needs to be opened or closed, the gear is driven to rotate by rotating the rotating handle, the rack is also translated along with the rotation of the gear due to the tight meshing of the gear and the rack, and similarly, the rack is driven to rotate by the translation of the rack due to the tight meshing of the rack and the gear rotating shaft, and the gear rotating shaft is connected with the door curtain strip hanging rod, so that the door curtain strip is rotated by taking the gear rotating shaft as an axis.
As an optimized structure of the invention: the rotation angle of the door curtain strip in the door curtain is 0-90 degrees.
As an optimized structure of the invention: the door curtain strip is made of semitransparent materials.
As an optimized structure of the invention: the transmission device also comprises a positioning block, the positioning block is arranged in the transverse hanging rod of the door curtain and clings to one smooth side of the rack, and the positioning block clings to the other smooth side of the rack due to the fact that one side of the rack is tightly meshed with the gear and the gear rotating shaft, so that the movement direction of the rack can be limited, and the rack can only be driven to perform translational movement by the rotation of the gear.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
