Description

Technical Field

[0001] This utility model belongs to the field of tent or blind technology, and in particular relates to a rotating device for a tent. 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 rotating device suitable for windows or tents that is windproof, rainproof, light-transmitting, and well-ventilated, 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 a tent includes louvers and a rotating component. The louvers are U-shaped bodies with one side of a flat plate bent downward and outward to form an inclined insert, and the other side having an opening pointing towards the inclined insert. The flat plate has two or more longitudinally recessed first grooves spaced apart. The rotating component is symmetrically arranged at the front and rear ends of the lower surface of the flat plate of the louvers. The upper surface of the rotating component has at least one second groove that matches the first grooves. The louvers are fixedly connected to the rotating component. The rotating component has a pivot mounting hole in the middle and a linkage hinge hole on the side of the rotating component away from the louvers and the pivot mounting hole.

[0007] As a further optimization of the above technical solution, two or more through holes are provided on the outer side of the first groove on the louver, and mounting holes are provided on the rotating component corresponding to the through holes. The screw passes through the through holes on the louver and is screwed onto the mounting holes on the rotating component to fix the louver and the rotating component in place.

[0008] As a further optimization of the above technical solution, a rectangular hole communicating with the mounting hole is provided on one side of the rotating component. After the screw passes through the through hole on the louver and the mounting hole on the rotating component, it is threadedly connected to the nut fed into the rectangular hole of the rotating component.

[0009] As a further optimization of the above technical solution, the U-shaped body is formed by sequentially bending downward, outward, upward, and inward on the other side of the flat plate.

[0010] As a further optimization of the above technical solution, the first groove and all bends of the louver are smoothly transitioned.

[0011] As a further optimization of the above technical solution, both the first groove and the second groove are triangular grooves, trapezoidal grooves, or arc-shaped grooves.

[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 through hole centered on the outwardly extending cylinder, which is aligned with the small diameter of the stepped hole.

[0013] As a further optimization of the above technical solution, grooves are provided on both sides of the rotating component between the shaft mounting hole and the linkage rod hinge hole.

[0014] As a further optimization of the above technical solution, an outwardly extending annular boss is provided at the hinge hole of the linkage rod on one side of the rotating component.

[0015] As a further optimization of the above technical solution, the rotating component is a near-obtuse triangle, the linkage rod hinge hole is located at an angle less than 90 degrees of the obtuse triangle, the rotating shaft mounting hole is located on the lower side of the second groove, and a protruding edge is provided on the middle part of the side wall of the rotating component at the linkage rod hinge hole, extending outward and surrounding the side wall, and the plane where the protruding edge is located is parallel to the side of the rotating component.

[0016] The advantages of this invention compared to the prior art are:

[0017] 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.

[0018] 2. The louvers of this utility model are fixedly connected to the rotating parts, which increases their strength. In use, the louvers are opened and closed by the swing of the linkage rod driven by the motor, and the rotation angle is consistent, making it convenient to use.

[0019] 3. When using this utility model, the inclined insert of one louver is inserted into the U-shaped body of another louver. When it rains, the rainwater can be guided into the U-shaped body and discharged from both ends without affecting the breathability. It has good rainproof and breathable properties.

[0020] 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
