Description

Technical Field

[0001] The utility model relates to the technical field of shutters, in particular to a shutter with a closed cover. Background Art

[0002] Venetian blinds are a type of window that originated in China. There are several styles of blind structures available on the market today, which are generally installed on doors and windows at home to block sunlight and provide decoration. Depending on the needs of different consumers, conventional Venetian blinds rotate the blind blades by pulling the cord or bead by hand to achieve the closing and closing actions.

[0003] The open covers currently used in the market have been used for decades due to their easy molding and installation characteristics. However, under the open covers, the blades are exposed to the cover regardless of whether they are in a closed or hanging state. In this state, on the one hand, dust is easily accumulated in the cover and is difficult to clean. On the other hand, the exposure of the shutters after folding not only affects the aesthetics of the shutters, but also causes shaking under external factors such as wind disturbance, colliding and scratching with the cover, and making noise. Therefore, we proposed a shutter with a closed cover that is convenient for blocking and closing the shutters to solve the above problems. Utility Model Content
