Benefits of technology
[0007]The present invention relates to a linkage rod for a vertical window blind transmission seat which comprises a clamping groove used to engage with a notch located at one side of the transmission seat, a blocking head formed at a front end of the linkage rod, an inward concave edge formed at one side of the linkage rod behind the clamping groove, a flange block formed on a top of the linkage rod behind the clamping groove, and a stopping block formed on a top of the linkage rod behind the clamping groove. The flange block, and the stopping block are located behind the clamping groove for engaging with an inserted sheet of a movable seat. Hence, the present invention can offer the following advantages:
[0008]Because the clamping groove is positioned by clamping the notch of the transmission seat, the clamping groove can be positioned on the transmission seats made by different producers, thus avoiding the problem of un
Problems solved by technology
Thereby, the conventional linkage rod can be only applied on a special structure, but cannot be used together with a general transmission seat.
Hence, once the linkage rod is damaged, the transmission seat must be replaced together with the linkage rod, thus wasting the use cost and resource.

Embodiment Construction
[0014]The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
[0015]Referring to FIGS. 1-2, a linkage rod 2 for a vertical window blind transmission seat comprises a clamping groove 21, a blocking head 22, an inward concave edge 23, a flange block 24 and a stopping block 25. The clamping groove 21 used to engage with a notch 11 located at one side of the transmission seat 1. The blocking head 22 is formed at the front end of the linkage rod 2. The inward concave edge 23 is formed at one side of the linkage rod 2 and located behind the clamping groove 21. The flange block 24 and the stopping block 25 are formed on the top of the linkage rod 2 and located behind the clamping groove 21 for engaging with the inserted sheet 31 of a movable seat 3. By such arrangements, after the linkage rod 2 is placed on a link...

A linkage rod for a vertical window blind transmission seat comprises a clamping groove used to engage with a notch located at one side of the transmission seat, a blocking head formed at a front end of the linkage rod, an inward concave edge formed at one side of the linkage rod, a flange block formed on a top of the linkage rod, and a stopping block formed on a top of the linkage rod. After the linkage rod is placed on a linkage sheet by utilizing the inward concave edge to pass through the inserted sheet, the flange block is made to force the inserted sheet to elastically deform upwards, so as to be pulled out, thus making the flange block and the stopping block be locked at the front and back ends of the inserted sheet respectively for realizing a fixed connection of the transmission seat with the movable seat.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a linkage rod for a vertical window blind transmission seat which comprises a clamping groove used to engage with a notch located at one side of the transmission seat, a blocking head formed at a front end of the linkage rod, an inward concave edge formed at one side of the linkage rod, a flange block formed on a top of the linkage rod, and a stopping block formed on the top of the linkage rod. The flange block, and the stopping block are located behind the clamping groove for engaging with an inserted sheet of a movable seat, by such arrangements, the operation of pulling the linkage rod out causes an elastic deformation of the inserted sheet to make the flange block pass through the space under the inserted sheet, so as to restrict the inserted sheet between the flange block and the stopping block, thus realizing a linkage of the transmission seat and a fixed connection with the movabl...
