Description

Technical Field

[0001] The utility model relates to the technical field of curtain accessories, in particular to a pulley of a curtain slide rail. Background Art

[0002] Curtains are used to block sunlight and ultraviolet rays, and Venetian blinds are a new type of curtains. Venetian blinds are composed of multiple vertical curtain bodies, and the upper ends of the multiple curtain bodies are fixed by curtain buckles. However, when the existing curtain body is driven by a pulley to open or close the curtain, that is, when the curtain is opened, the multiple curtain bodies are retracted to one side at the same time, so as to open the window. However, since each curtain body has a certain width, after the multiple curtain bodies are retracted to one side, a relatively wide covering position will still be formed, thereby blocking one side of the window, so that the curtain cannot be maximized after opening.

The lower end of the gear member 10 is used to connect the curtain body, so that the curtain body can rotate independently. Since the protrusion 15 corresponds to the protrusion plate 13, when the protrusion plate 13 on the limiting gear member 10 rotates, until the protrusion plate 13 rotates to the protrusion 15, the limiting gear member 10 cannot rotate, and the curtain body can be rotated to a certain angle, so that light can be transmitted between two adjacent curtain bodies, so as to facilitate the curtain to adjust the light transmission. At the same time, when the transmission gear member is engaged with the transmission belt and the transmission belt is further operated, it can also drive the entire pulley to move, so that the pulley drives the curtain body to move, thereby realizing opening or closing the curtain. The overall structure is simple and compact, which can maximize the realization of the curtain after opening and reduce obstruction.

[0022] like Figure 2 and Figure 4 As shown, the frame body of this embodiment includes a lower frame 1 and an upper frame 3, the gear box 2 is arranged on the lower frame 1, and a plug plate 7 located on the lower frame 1 is arranged on one side of the gear box 2, and a clamping block 22 is arranged on the side of the plug plate 7 away from the gear box 2, and only a slot plate 21 is arranged at the lower end of one side of the upper frame 3, and a slot 24 corresponding to the plug plate 7 is arranged on one side of the slot plate 21, and a positioning groove 25 corresponding to the clamping block 22 is opened at the lower end of the slot 24, and the sliding belt groove 4 is located on one side of the upper end of the upper frame 3; by inserting the plug plate 7 of the lower frame 1 into the slot plate 21, and the clamping block 22 is clamped into the positioning groove 25, the structure between the lower frame 1 and the upper frame 3 is more stable to prevent loosening, and the installation is simple and quick.

[0023] It is worth noting that, in this embodiment, an upper hook groove 29 is provided on the side of the upper frame 3 close to the transmission gear part, and a lower hook groove 30 is provided on one side of the gear box 2, and the lower hook groove 30 is located directly below the upper hook groove 29, so that a belt groove is formed between the upper hook groove 29 and the lower hook groove 30; a part of the transmission gear part is located in the belt groove, and a transmission belt is passed through the belt groove, and the transmission belt has teeth on the side close to the transmission gear part, so that the transmission gear part is meshed with the transmission belt, and the belt groove formed can prevent the transmission belt from detaching from the transmission gear part.
