Description

Technical Field

[0001] This utility model relates to the field of louver technology, and in particular to an adjustable louver. Background Technology

[0002] Plastic Venetian blinds are a common interior design feature in newly built homes, and are frequently used in renovations. The convex and concave surfaces of the slats block outside views while allowing light in. At night, with the convex side of the slats facing inwards, shadows won't be reflected outside, ensuring a clean and safe viewing experience. They are also easy to clean. Compared to curtains, Venetian blinds offer the added benefit of adjustable slats.

[0003] Chinese Patent Publication No. CN211950267U discloses a solar-powered adjustable venetian blind that can automatically rotate and open or close vertical venetian blinds according to the intensity of incident light. It features a high degree of automation and makes full use of solar energy, thus saving energy. The invention relies on a rotating curtain cord to drive a disc wheel to rotate and move the blinds, resulting in a simple structure. Both sides of the venetian blinds are made of reflective material, effectively reflecting external optical fibers into the room when the blinds are open, increasing indoor light intensity, temperature, and brightness. It offers both automatic and manual adjustment modes for user selection.

[0004] However, compared with existing technologies and comparative documents, existing adjustable blinds adjust the amount of light entering the room by rotating the slats during use. However, there are gaps between the tilted slats, which makes it easy for mosquitoes from the outside environment to enter the room through the gaps between the slats, thus failing to prevent mosquitoes and reducing practicality. Utility Model Content

[0005] The main purpose of this invention is to provide an adjustable louver.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] An adjustable venetian blind includes a window frame, multiple blades evenly spaced within the window frame, a support shaft fixed in the center of each blade, two sets of protective components symmetrically mounted on each blade, and a transmission component mounted at the top of the support shaft. One end of the transmission component is connected to a drive component. The protective components include a curtain fixed to the blades, and an edge sealing fabric fixed to the end of the curtain away from the blades, with an absorbent plate fixed inside the edge sealing fabric.

[0008] Preferably, the bottom end of the support shaft is rotatably connected to the window frame, and the top end of the support shaft is fixedly connected to the transmission assembly.

[0009] Preferably, the transmission assembly comprises a transmission wheel fixedly connected with the support shaft, a driving wheel is engagedly connected on the upper side of the transmission wheel, and the included angle between the driving wheel and the transmission wheel is 90°.

[0010] Preferably, a main shaft is connected in the middle of the driving wheel, and a key groove connected with the driving wheel is formed on the main shaft.

[0011] Preferably, the driving assembly comprises a motor located at the top end of the window frame, and a connecting shaft is fixedly connected to the output end of the motor.

[0012] Preferably, two sets of synchronous wheels are correspondingly installed on the connecting shaft and the main shaft.

[0013] Preferably, a synchronous belt is engagedly connected on the outer side of the two sets of synchronous wheels, and a tooth groove engaged with the synchronous belt is formed on each of the two sets of synchronous wheels.

[0014] The beneficial technical effects are that:

[0015] By setting the protection assembly, after adjusting the inclination angle of the blades, the protection assemblies at the front and rear ends of the blades rotate synchronously with the blades, when the two protection assemblies approach each other, the adsorption plates in the edge cloth are attracted to each other due to the existence of magnetism, so that the screen is located between the two blades, the gap between the blades is protected by the screen, mosquitoes are prevented from entering, the mosquito prevention effect is improved, and the practicability of the shutter is increased.
