Embodiment 1

[0015] Embodiment 1: as figure 1 . The curtain cloth or blinds 7 driven by the winding rope 4a of the notch 1a of 1, and the deceleration device 2 are composed of the power box 3a fixed on the curtain bracket 1 and the one-way rotation clutch device arranged in the power box 3a. 3b. The pull cord turntable 3c that drives the action of the one-way rotation clutch device 3b is formed. The pull cord turntable 3c is driven to rotate by the pull cord or the bead chain 3d. The rotating shaft 3b3 driven by the transmission shaft 6 in the shaft hole 3b1 of the clutch body and the clutch sliding rotating head 3b4 at one end of the rotating shaft 3b3 are formed. To the meshing right triangle tooth 3b5, a guide shaft 3b9 is provided in the middle of the end face of the rotating shaft 3b3, the clutch sliding head 3b4 is rotated and arranged on the guide shaft 3b9, the side of the pull rope turntable 3c is provided with a sleeve 3c1, and the other end of the clutch sliding head 3b4 Locat...

Embodiment 2

[0019] Embodiment 2: as Figure 6 , 7, the present embodiment is on the basis of embodiment 1, and there are two sets of rotating drive unit 3, rope winding device 4, curtain cloth or louver 7, deceleration device 2, wherein, rotating driving unit 3, rope winding device 4. The deceleration device 2 is arranged symmetrically on the curtain bracket 1, and the two curtain fabrics or louvers 7 are connected together from top to bottom. In this way, the curtain has two curtain functions to meet the needs of consumers.

Abstract

The invention provides a curtain, which is characterized in that: the curtain mainly comprises a curtain bracket, rotating-driving devices arranged on two ends of the curtain bracket, a rope winding device arranged on the curtain bracket, a curtain cloth or a shutter driven by the rope winding device, as well as a speed reducing device; and each rotating-driving device consists of a power box fixed on the curtain bracket, a unidirectional rotary engaging-disengaging device arranged in the power box, as well as a pull rope turntable driving the unidirectional rotary engaging-disengaging device to move. Compared with the prior art, the curtain has the advantages of simple structure, convenient use, low cost and easy expanding functions.

Description

Technical field: [0001] The invention relates to a curtain. Background technique: [0002] Existing curtains that drive curtain cloth or blinds to move up and down by winding ropes are composed of curtain brackets, rotating drive devices arranged on the curtain brackets, rope winding devices driven by the rotating drive devices and deceleration devices arranged on the supports. This kind of curtain, its rotation driving device and deceleration device are respectively located at the two ends of the curtain bracket, limited by the above-mentioned structure, the function of expanding the curtain (such as setting a variety of curtain fabrics) is greatly restricted. In addition, in order to be able to To realize the function of automatically releasing the curtain, a one-way rotating device and a clutch device connected together with the rotating drive device must be respectively provided, which increases the complexity of the structure and improves the overall cost of the product...
