Description

Shutter rotating device with arc top Technical Field The utility model belongs to the technical field of tents or shutters, and particularly relates to a shutter rotating device with an arc top. Background At present, the shutter rotating structure for shutters and the like is controlled to open and close and lift by a pull wire, and has the defects of being only used for shading or transmitting light of windows and having poor wind resistance and rain resistance. At present, tents are made of tarpaulin materials, although some tents are made of transparent materials for light transmission, the ventilation performance is poor, the odor in the tents needs to be rapidly dispersed sometimes, if the roofs are not opened, the situations that the rapid light transmission and ventilation are needed cannot be achieved, and of course, although the bad odor in the tents is little, the good ventilation with the air outside the tents is also expected, and the good ventilation of the air inside and outside the tents is also needed to be achieved by opening the roofs. Disclosure of Invention The utility model aims to provide a shutter rotating device which has good wind resistance, rain resistance, light transmission and ventilation performance and can be freely rotated to open and close and is suitable for a window or a tent with an arc top. The utility model aims to solve the following problems: The utility model provides a take tripe rotating device on arc top, includes tripe and rotating piece, the tripe is bent many times in the one side of bellied arc portion that makes progress and forms the first U type body of opening inwards, the opposite side is bent many times and is formed the second U type body of opening downwardly directed, the lower surface symmetry of the front and back end of arc portion is provided with rotating piece, upper surface be provided with rotating piece fixed connection in order to fix the arc body of tripe, rotating piece and arc body with the face that arc portion contacted is the arcwall face of mutual matching, the middle part of rotating piece upper surface is provided with bolted connection portion, both sides are provided with upwards extending reference column, be provided with on the tripe with bolted connection portion and reference column assorted through-hole, be provided with on the arcwall face of arc body with bolted connection portion and reference column assorted mounting hole and recess, the middle part of rotating piece is provided with the pivot hinge hole, one side that rotating piece kept away from tripe and pivot hinge hole is provided with the gangbar hinge hole.
