Description

Technical Field

[0001] This utility model belongs to the technical field of tents or blinds, and particularly relates to a rotating device for blinds with an arc top. Background Technology

[0002] Currently, the louver rotation structure used for blinds and other similar products is controlled by a pull cord to open, close, and raise and lower. Its shortcomings are that it can only be used for shading or letting light through windows, and its wind and rain resistance is poor.

[0003] Most tents are made of tarpaulin-type materials. Although some tents use transparent materials for the top to let in light, they have poor ventilation. Sometimes, it is necessary to quickly dissipate the odor inside the tent. If the top is not opened, it is impossible to achieve the situation where quick light and ventilation are required. Of course, sometimes even if there is very little unpleasant odor inside the tent, it is still desirable to have good air circulation with the outside air. This can also be achieved by opening the top to allow good air circulation between the inside and outside of the tent. Summary of the Invention

[0004] The purpose of this invention is to provide a louvered rotating device suitable for windows or tents with arched roofs that is windproof, rainproof, light-transmitting, and air-permeable, and can be freely rotated and opened.

[0005] The purpose of this utility model is to solve the following problem:

[0006] A rotating device for louvers with an arc-shaped top includes louvers and rotating components. The louvers are formed by multiple bends on one side of an upwardly protruding arc-shaped portion to form a first U-shaped body with an inward opening, and multiple bends on the other side to form a second U-shaped body with an downward opening. Rotating components are symmetrically arranged on the lower surface of the front and rear ends of the arc-shaped portion, and arc-shaped bodies are arranged on the upper surface of the arc-shaped portion to fix the louvers by being fixedly connected to the rotating components. The surfaces of the rotating components and arc-shaped bodies that contact the arc-shaped portion are mutually matching arc-shaped surfaces. A bolt connection portion is provided in the middle of the upper surface of the rotating component, and positioning posts extending upward are provided on both sides. The louvers are provided with through holes that match the bolt connection portion and positioning posts. The arc-shaped surfaces of the arc-shaped bodies are provided with mounting holes and grooves that match the bolt connection portion and positioning posts. A pivot hinge hole is provided in the middle of the rotating component, and a linkage rod hinge hole is provided on the side of the rotating component away from the louvers and pivot hinge hole.

[0007] As a further optimization of the above technical solution, the two sides of the louvered arc section and the sidewalls of the through hole are bent downward to form steps, and the height of the steps is less than the height of the positioning post.

[0008] As a further optimization of the above technical solution, the linkage rod hinge hole, the shaft hinge hole, and the positioning post on one side of the rotating component are located on a straight line, and the positioning post on the other side of the rotating component is located above the linkage rod hinge hole.

[0009] As a further optimization of the above technical solution, the bolt connection part on the rotating part includes a blind hole in the middle of the upper surface of the rotating part, a rectangular hole perpendicular to the blind hole and penetrating the side wall of the rotating part and the blind hole, and a screw passing through the mounting hole on the arc-shaped body and the through hole on the louver and threadedly connected to a nut fed from the rectangular hole of the rotating part.

[0010] As a further optimization of the above technical solution, the first U-shaped body of the louver includes one side of the arc portion that is bent diagonally downward, horizontally outward, upward, and inward in sequence to form a first U-shaped body with an inward opening.

[0011] As a further optimization of the above technical solution, the second U-shaped body of the louver includes the arc portion bending diagonally downward, horizontally outward, upward, horizontally outward, and downward in sequence to form a second U-shaped body with an opening facing downward.

[0012] As a further optimization of the above technical solution, one side of the rotating shaft mounting hole on the rotating component is a stepped hole, and the other side is a first annular platform extending outward from the side wall of the rotating shaft mounting hole.

[0013] As a further optimization of the above technical solution, the rotating component has a second annular platform extending outward from the side wall of the linkage hinge hole on the side of the first annular platform, and the height of the first annular platform is higher than the height of the second annular platform.

[0014] As a further optimization of the above technical solution, a hollow part is provided on the rotating part between the shaft mounting hole and the linkage rod hinge hole.

[0015] The advantages of this invention compared to the prior art are:

[0016] 1. The louvers of this utility model adopt a profile structure, and the rotating parts are made of metal or plastic materials, which have good wind and rain resistance.

[0017] 2. The louvers of this utility model are fixedly connected with the rotating component and the arc-shaped body, which increases their strength. In use, the louvers are opened and closed by manually or by motor driving the swing of the linkage rod 41, which is hinged to the linkage rod hinge hole 34 of the rotating component. The rotation angle is consistent and easy to use.

[0018] 3. When using this utility model, the first U-shaped body 16 of one louver is inserted into the second U-shaped body 11 of another louver. When it rains, the rainwater can be guided into the second U-shaped body 11 through the protrusion of the arc-shaped part 14 and discharged uniformly from both ends without affecting the breathability. It has good rainproof and breathable properties.

[0019] 4. This utility model has a simple structure, low production cost, good wind and rain resistance, light and wind transmission performance, and long service life. It can be used to assemble larger tents with openable tops or for larger windows, making it easy to promote and apply. Attached Figure Description

The rotating component 30 has a bolt connection part in the middle of its upper surface 22 and a positioning post 36 extending upward on both sides. The louver 10 has a through hole 12 that matches the bolt connection part and the positioning post 36. The lower surface 22 of the arc-shaped body 20 has a mounting hole 21 and a groove 23 that match the bolt connection part and the positioning post 36. The rotating component 30 has a pivot hinge hole 32 in the middle and a linkage rod hinge hole 34 on the side of the rotating component 30 away from the louver 10 and the pivot hinge hole 32.

[0028] As a further optimization of the above technical solution, the two sides of the arc-shaped part 14 of the louver 10 and the side wall of the through hole 12 are bent downward to form steps 14 and 15, and the height of the steps 14 and 15 is less than the height of the positioning post 36.
