Description

Technical Field

[0001] The utility model relates to the technical field of Roman rod structures, in particular to a Roman rod structure of a curtain. Background Art

[0002] The earliest curtain structure used a rope system. The curtain was raised and lowered by ropes and pulleys. This structure is more commonly used in simple curtains, but there are problems such as the ropes are easy to get tangled and difficult to operate. With the advancement of technology, the manual chain system was introduced into the Roman rod structure. It controls the rise and fall of the curtain through a manual device equipped with a ball chain. This structure is more convenient and easy to use, and has become one of the mainstream structures of the Roman rod. In order to further improve the convenience of operation, the spring system was introduced into the Roman rod.

[0003] However, most of the existing Roman rod structures are single-tube integrated structures. However, if a particularly long Roman rod is required, the Roman rod is not only inconvenient to transport and install, but also the whole-rod Roman rod structure is not suitable for the subsequent combination and assembly operations of longer rods. Therefore, the above problems need to be improved. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example: See Figure 1-5A Roman rod structure of a curtain in the utility model comprises two tube bodies 1, a connecting sleeve 2 is installed at the connection between the two tube bodies 1, and the length of the Roman rod can be increased by the connecting sleeve 2; a fixing frame 3 is installed on the rear side of the outer ends of the two tube bodies 1, and the entire Roman rod can be fixed to the wall by the fixing frame 3; a blocking block 4 is provided inside the opening at the outer end of the tube body 1, and the blocking block 4 can prevent larger debris from entering the tube body 1 and clogging it; a sliding groove is provided at the bottom of the two tube bodies 1, and a plurality of hanging rings 9 for curtain installation are slidably connected inside the sliding groove; a driving ring 7 is also slidably connected to the inner end of the sliding groove; a driving component is provided inside the tube body 1.

[0020] In the utility model, the driving assembly includes a screw rod 6 which is arranged inside the tube body 1 and rotates transversely, a micro motor 10 which is coaxially fixed to the screw rod 6 and a threaded tube which is sleeved on the screw rod 6. The rotation of the screw rod 6 can drive the driving ring 7 and thus drive the hanging ring (9); the micro motor 10 can drive the rotation of the screw rod 6; a connecting rod is arranged at the bottom end of the threaded tube, and a rectangular strip is opened transversely on the bottom surface of the tube body 1, and the connecting rod extends from the rectangular strip and is fixed to the top of the driving ring 7 at the bottom of the inner end of the tube body 1. The inner end of the screw rod 6 is provided with a bearing 5 which is fixed in the inner end of the tube body 1, and the bearing 5 is conducive to the rotation of the screw rod 6. The cross section of the crossbeam of the fixing frame 3 is an I-shaped cross section. The inner walls of both ends of the connecting sleeve 2 are provided with internal threads, and the outer wall of the inner end of the tube body 1 is provided with an external thread which matches the connecting sleeve 2.

[0021] Working principle: When the utility model is used, after determining the height of the Roman rod, first fix the fixing frame 3 on the wall, and then put the tube body 1 on the fixing frame 3. If the length of the Roman rod is not longer than that of the tube body 1, fix the connecting sleeve 2 at one end of the tube body 1, and then connect one end of the other tube body 1 to the connecting sleeve 2. After the curtain is connected to the hanging ring 9 on the driving ring 7, then the micro motor 10 is electrically connected to the external control device through a wire, and the micro motor 10 is started to drive the screw rod 6. When the screw rod 6 rotates counterclockwise, the driving ring 7 will pull the curtain and drive the hanging ring 9 away from the end with the micro motor 10. At this time, the curtain is closed. When the screw rod 6 rotates clockwise, the driving ring 7 will pull the curtain and drive the hanging ring 9 close to the end with the micro motor 10. At this time, the curtain is opened.
