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. Background Technology

[0002] Currently, the rotating structure of louvers used in 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 currently made of tarpaulin or plastic sheeting. Although some tents use transparent materials for the top to allow light to pass through, 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 customers also want better air circulation between the inside and outside of the tent, and they also need to be able to achieve better air circulation by opening the top. Summary of the Invention

[0004] The purpose of this invention is to provide a louvered rotating device suitable for tents or windows 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 a louver includes a louver and a rotating component. The louver is formed by bending one side of a flat plate downward and outward to form an inclined insertion portion, and the other side is formed by sequentially bending a lower edge, an outer edge, and an upper edge to form an upward-facing U-shaped body. The outer wall end of the U-shaped body is first bent inward and then bent upward to form a locking portion. The flat plate is provided with two or more longitudinally downward recessed first grooves at intervals. The front and rear ends of the lower surface of the flat plate of the louver are symmetrically arranged with rotating components. The upper surface of the rotating component is provided with at least one second groove that matches the first groove. One side of the upper surface of the rotating component is provided with a hook that engages with the locking portion and can accommodate the U-shaped body. The louver is fixedly connected to the rotating component. The middle of the rotating component is provided with a pivot mounting hole, and the side of the rotating component away from the louver and the pivot mounting hole is provided with a linkage hinge hole.

[0007] As a further optimization of the above technical solution, both ends of the louver are provided with a rear-flanged edge to form a louver reinforcement.

[0008] As a further optimization of the above technical solution, the first groove on the louver is a first trapezoidal groove, and the second groove on the rotating component is a second trapezoidal groove that matches the first trapezoidal groove.

[0009] As a further optimization of the above technical solution, the first trapezoidal groove has three sections, and the second trapezoidal groove has two sections.

[0010] As a further optimization of the above technical solution, the rotating component is formed by an inclined plate extending downward and outward from the lower surface of one side of a strip-shaped body, the rotating shaft mounting hole is installed in the middle of the strip-shaped body, and the linkage rod hinge hole is installed at the tail of the inclined plate.

[0011] As a further optimization of the above technical solution, the strip body and the inclined plate have a smooth transition, the thickness of the strip body is greater than the thickness of the inclined plate, one side of the strip body is flush with one side of the inclined plate, and the side of the inclined plate that is flush with the side of the strip body extends out a positioning protrusion that is flush with the side of the strip body.

[0012] As a further optimization of the above technical solution, a first protruding ring is provided outward from the shaft mounting hole on one side of the rotating component, and a second protruding ring is provided outward from the linkage rod hinge hole on the other side of the rotating component.

[0013] As a further optimization of the above technical solution, the inner diameter of the side away from the first convex ring shaft mounting hole is expanded to form a first expanded diameter section, and the inner diameter of the side away from the second convex ring linkage rod hinge hole is expanded to form a second expanded diameter section.

[0014] As a further optimization of the above technical solution, two or more weight-reducing grooves are respectively provided on the rotating side surfaces of the two sides of the first convex ring.

[0015] As a further optimization of the above technical solution, a threaded groove is provided on the plane outside the second groove on the rotating part, and the louver is fixedly connected to the rotating part by screwing it into the threaded groove.

[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. When this utility model is used, the louvers are fixedly connected to the rotating parts. The hook on one rotating part engages with the locking part on another louver, which fixes them together to increase strength. The opening and closing of the louvers is driven by the swing of the linkage rod driven by the motor. The rotation angle is consistent and 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
