Description

Technical Field

[0001] This utility model belongs to the technical field of tents or blinds, and particularly relates to a rotating device for tent blinds. 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 currently made of tarpaulin-type materials. Although some tents use transparent materials for the top to let in light, they have poor ventilation and cannot be used when light and air need to pass through. Summary of the Invention

[0004] The purpose of this invention is to provide a louvered rotating unit 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 tent blinds includes blinds and rotating components. The blinds have a first U-shaped body with a downward opening on one side of an upwardly bulging arc-shaped portion and a second U-shaped body with an opening pointing towards the first U-shaped body on the other side. The arc-shaped portion has two or more downwardly recessed first grooves spaced apart. Rotating components matching the lower surfaces of the arc-shaped portion and the first grooves are provided on the lower surfaces of the front and rear ends of the blinds. Cover plates are provided on the upper surfaces of the blinds. The cover plates are fixedly connected to the cover plates, blinds, and rotating components by screws passing through the cover plates and the blinds and screwing them into the threaded holes at the bottom of the first grooves. The rotating components have a first hinge hole in the middle for mounting a rotating shaft, and a second hinge hole on the side of the rotating components away from the cover plates for hinged connection with a linkage rod.

[0007] As a further optimization of the above technical solution, the cover plate is provided with a first protrusion that matches and engages with the first groove relative to the two or more first grooves.

[0008] As a further optimization of the above technical solution, the bottom of the second groove corresponding to at least one of the first grooves on the rotating component is provided with a threaded hole, and the screw passes through the cover plate and the louver and is screwed into the threaded hole to fix the cover plate, the louver and the rotating component relatively.

[0009] As a further optimization of the above technical solution, a second groove is provided at each of the first groove locations on the rotating component, a positioning post is provided between two adjacent second grooves, a positioning hole is provided on the louver corresponding to the positioning post, and a positioning groove is provided on the cover plate corresponding to the positioning post.

[0010] As a further optimization of the above technical solution, the cross-section of the louver is formed by three folds on one side of the arc-shaped portion, one side opening downwards, and the other side opening upwards and inwards, forming a second U-shaped body with the opening facing the first U-shaped body.

[0011] As a further optimization of the above technical solution, the upper bottom of the first U-shaped body is higher than the upper surface of the second U-shaped body.

[0012] As a further optimization of the above technical solution, the rotating component is provided with two or more hollowed-out parts.

[0013] As a further optimization of the above technical solution, the second hinge hole is located on the side away from the cover plate and the first hinge hole.

[0014] As a further optimization of the above technical solution, the louver is a profile structure made of metal or plastic material, and the rotating part and the cover plate are an integrated structure made of metal or plastic material.

[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 and cover plates are made of metal or plastic materials, which have good wind and rain resistance.

[0017] 2. The louvers of this utility model increase each other's strength through the clamping of the rotating parts and the cover plate. In use, the opening and closing of the louvers is driven by the swing of the linkage rod driven by the motor, and the rotation angle is consistent, making it convenient to use.

[0018] 3. This invention can be used to assemble larger tents with openable tops or for larger windows.

[0019] 4. This utility model has a simple structure, low production cost, good wind and rain resistance, light and wind transmission performance, long service life, and is easy to promote and apply. Attached Figure Description
