The moving assembly drives the moving beam to move, so that direct friction between the moving beam and the guide groove is avoided, and the loss speed of the moving beam is reduced.
Specifically, a moving block and a clamping block pressed on the moving block are arranged on the moving beam, and the moving block is connected in the window frame in a sliding way; a rope penetrating through hole for the steel wire rope to pass through and a fixing hole for the steel wire rope to connect are formed between the moving block and the clamping block. The head end and the tail end of the steel wire rope are connected with the movable beam through the connection with the fixed hole; the other side of the steel wire rope is arranged in the rope threading through hole in a penetrating way, so that unnecessary shaking of the steel wire rope is limited.
Specifically, a guide rope for guiding the moving direction of the day curtain is arranged in the day curtain; one end of the guide rope is connected to the sky curtain, and the other end of the guide rope passes through the sky curtain along the sliding direction of the moving beam and is connected to a window frame far away from the sky curtain; the moving block is internally provided with a steering wheel for tensioning the guide rope. The motion track of the day curtain in the process of opening or folding is guided, so that the opening or folding process is smoother; the unnecessary problem caused by random shaking of the day curtain after the day curtain is opened to a certain degree is avoided.
Specifically, an elastic piece with an elastic expansion direction parallel to the sliding direction of the moving beam is connected between the head end of the steel wire rope and the moving beam. The elastic piece can provide a buffer effect when the motion state of the moving beam changes suddenly, so that the loss speed of the moving beam is reduced.
The beneficial effects of the invention are as follows: the problem that the transmission piece is easy to age and lose efficacy is avoided, the automatic adjustment can be realized for the condition that the two sides of the skylight curtain move asynchronously, the cost is reduced, and the installation is convenient.
