Description

Technical Field

[0001] The invention relates to a hand pull rod, in particular to a curtain hand pull rod structure used for the opening and closing action of a push-pull curtain. Background Art

[0002] Curtains are an indispensable home decoration in modern families. When designing curtains, for larger and heavier curtains such as floor-to-ceiling windows, or curtains that are inconvenient to open and close in corners, especially double-curtain curtains, a curtain rod is usually designed to assist in opening and closing the curtains.

[0003] There is a curtain hand pull rod structure, please Fig.10 , 11 As shown, it includes a hand pull rod 50, and a horizontal through hole 51 is set on both sides of the top of the hand pull rod 50, and a pull ring body 52 is installed through the through hole 51. The pull ring body 52 is usually annular or triangular. The illustrated embodiment is described with a triangular pull ring body 52. ​​A rod segment 521 of the pull ring body 52 is passed through the through hole 51, and the hand pull rod 50 can swing on the rod segment 521 through the through hole 51, and then the pull ring body 52 is assembled on a connecting frame 53. The pull ring body 52 is hung on the through hole 531 of the connecting frame 53 at a symmetrical angle relative to the rod segment 521. Finally, the connecting frame 53 is assembled on a curtain slide 54 so that the curtain slide 54 can be pushed and pulled by the hand pull rod 50 to open and close.

[0004] A detailed look at the above-mentioned existing structure shows that it still has some shortcomings, the main reasons are as follows: the existing hand-pull rod 50 can only swing on the pull ring body 52 by using the through hole 51. Although the swing direction of the hand-pull rod 50 is the same as the push-pull direction of the curtain, when the curtain is actually pushed and pulled by the hand-pull rod 50, the hand-pull rod 50 is usually twisted inadvertently due to the standing position or when pushing and pulling. This not only affects the smoothness of the push-pull movement of the curtain, but also causes the pull ring body 52 and the connecting frame 53 to rub against each other, and then gradually pulls the gap of the pull ring body 52 open, causing the hand-pull rod 50 to be out of the gap of the pull ring body 52. ​​It lacks practicality and durability, and there is indeed a need for improvement.

[0005] In view of this, the inventor, with many years of experience in manufacturing, developing and designing related products, has finally obtained a practical invention after detailed design and careful evaluation for the above-mentioned goals. Summary of the invention
