The semi-enclosed shell has an extension piece on one side of the blade, and the semi-enclosed shell and the extension piece are disposed opposite each other on the other side of the blade to form a receiving cavity for accommodating the blade. When the blade is rolled up, it is completely hidden in the receiving cavity.

[0006] Preferably, the semi-enclosed structure includes a main panel, a rear panel disposed opposite to the main panel, and a base plate for connecting the main panel and the rear panel. The main panel, the rear panel, and the base plate together form a braking cavity for mounting the roller shutter braking mechanism.

[0007] Preferably, the main panel and the rear panel are provided with arc-shaped buckles on opposite surfaces, and an upper top plate can be detachably installed between the two arc-shaped buckles to facilitate the installation and maintenance of the braking mechanism in the braking chamber.

[0008] Preferably, the rear panel has a groove on the side facing away from the main panel, the groove has a positioning protrusion, and the semi-enclosed shell has a center plate that cooperates with the positioning protrusion. When the semi-enclosed shell is connected to the semi-enclosed cover, the center plate is located above the positioning protrusion and placed in the groove.

[0009] Preferably, the rear panel is provided with a first folding plate above the positioning protrusion, and the semi-enclosed shell is provided with a second folding plate above the center plate that matches the first folding plate. The second folding plate is inserted into the interior of the first folding plate to fix the semi-enclosed shell.

[0010] Preferably, the first folding plate is folded downwards to form a side opening groove between itself and the rear panel, and the second folding plate is folded downwards and inserted into the side opening groove.

[0011] Preferably, the positioning protrusion or the bottom of the substrate is provided with a first protrusion, and the semi-enclosure is provided with a pressing plate below the center plate. The pressing plate is provided with a second protrusion. When the semi-enclosure is connected to the semi-enclosure, the first protrusion and the second protrusion engage with each other to further secure the semi-enclosure.

[0012] Preferably, the half-cover and half-shell are provided with end caps on both sides, and each end cap has a plug-in part at both ends for quick installation on both sides of the half-cover and half-shell.

[0013] To achieve the above objectives, this utility model provides the following technical solution:

[0014] The Venetian blind includes the aforementioned semi-enclosed shell, whose slats are rolled up inside the semi-enclosed shell.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The semi-enclosed cover of this utility model can be used in Venetian blinds or honeycomb blinds. It can completely store the slats in the rolled-up state, making it more simple and beautiful. At the same time, the semi-enclosed cover can be quickly assembled, installed and disassembled, which is convenient for maintenance. Attached Figure Description
