Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

The pulley mounting structure shown in fig. 1-4 comprises a connecting seat 10, a connecting rod 20 and a positioning piece, wherein the connecting seat 10 can be used for mounting a pulley. The specific connecting seat 10 is provided with an adjusting end 11, a connecting end is correspondingly arranged on the connecting rod 20, the connecting rod 20 can be slidably assembled with the adjusting end 11 of the connecting seat 10 through the connecting end, and the positioning piece can lock the connecting end and the adjusting end 11 after the connecting end and the adjusting end 11 are slidably assembled.

On the basis of the above structure, when the pulley mounting structure of the utility model is used, the connecting seat 10 can be assembled with the pulley, then the connecting seat 10 is assembled on the door and window frame through the structures such as bolts, the connecting rod 20 can connect two adjacent connecting seats 10, if the door and window frame is narrower, the distance between the two connecting seats 10 can be narrowed by enabling the connecting end of the connecting rod 20 to slide into the adjusting end 11 of the connecting seat 10 relatively, after the connecting end of the connecting rod 20 slides in place relatively to the adjusting end 11 of the connecting seat 10, the pulley mounting structure formed by matching the connecting rod 20 between the two adjacent connecting seats 10 can be adapted to the structure with narrower door and window frame, and the pulley on the two connecting seats 10 can slide and guide at two sides of the door and window frame.

If door and window frame is wider, then can be through making the link of connecting rod 20 slide out relatively in the regulation end 11 of connecting seat 10, the distance between two connecting seats 10 can widen, after the link of connecting rod 20 slides in place relative the regulation end 11 of connecting seat 10, can lock through the setting element, at this moment, two adjacent connecting seats 10 can adapt to the wider structure of door and window frame with the pulley mounting structure that connecting rod 20 cooperation formed, and the pulley on two connecting seats 10 can carry out the slip direction in the both sides of door and window frame.

Thus, the pulley mounting structure is applicable to door and window frame structures with different widths through sliding fit between the connecting rod 20 and the two adjacent connecting seats 10, and the application range is wider.

More specifically, in order to facilitate stable assembly between the connecting rod 20 and the connecting seat 10, the adjusting end 11 is provided with a through slot, the connecting end is slidably connected in the through slot, and a through hole is correspondingly arranged on the connecting end; the positioning piece is connected to the through hole in a penetrating way and is abutted to the connecting end, so that the connecting end and the adjusting end 11 are fixed. On the basis of the structure, when the connecting rod 20 is assembled with the connecting seat 10, the connecting end of the connecting rod 20 can be connected in the through groove of the connecting seat 10 in a sliding way, the assembling distance between the connecting rod 20 and the connecting seat 10 is adjusted through the sliding of the connecting rod 20 in the through groove, and after the connecting rod 20 is slid in place, the connecting rod can be connected to the through hole in a penetrating way through the locating piece and extend into the through groove to tightly prop the connecting end of the connecting rod 20.

Because the assembly of connecting rod 20 and connecting seat 10 is realized spacing through link and cross-under groove, therefore after the assembly, connecting rod 20 and connecting seat 10 adopt the mode of cup jointing to fix with the setting element, and the structure is more stable after the assembly. And when sliding, the sliding is guided by the through groove, so that the offset is reduced in the adjustment process, and the adjustment process is more stable.

Further, the through hole in this embodiment is a threaded hole, and the positioning member is a screw, and the screw is screwed to the threaded hole and abuts against the connection end, specifically when locking, the structure is more stable after locking by screwing to the threaded hole and penetrating into the connection end.

Of course, the positioning piece can also be in a bolt, rivet or other structure, or in a bolt structure or the like.

Further, above-mentioned cross-under groove includes circular arc groove section and guide way section, link up guide way section and circular arc groove section and link up, it is that connecting rod 20 is equipped with circular arc locking section 21 and slip section 22, circular arc locking section 21 and slip section 22 all extend along connecting rod 20's length direction, promptly when connecting rod 20 and wear to be assembled with the groove slip, circular arc locking section 21 can carry out sliding fit with the circular arc groove section of cross-under groove, and slip section 22 then can realize sliding fit with the guide way section of cross-under groove, because circular arc face that circular arc locking section 21 has is great in slip section 22 external diameter, circular arc locking section 21 and slip section 22 can be in the cross-under inslot stability slip when sliding, the condition of rocking appears in the reduction, sliding stability is better.

More specifically, the guiding groove section is connected to the bottom end of the circular arc groove section, the sliding section 22 corresponding to the guiding groove section can be connected to the bottom end of the circular arc locking section 21, that is, the sliding section 22 of the connecting rod 20 with the circular arc locking section 21 distributed up and down is respectively matched with the circular arc groove section and the guiding groove section distributed up and down, so that up and down shaking caused by sliding is reduced.

Further, including two at least connecting seats 10, sliding connection has connecting rod 20 between two adjacent connecting seats 10, when the door and window frame is assembled, can set up two at least connecting seats 10 in the bottom of door and window frame, all set up pulley structure on each connecting seat 10 and be used for bearing door and window frame, and the structure is more stable, and the interval between two adjacent connecting seats 10 all can be adjusted through connecting rod 20, and the interval between two adjacent connecting seats 10 all can be adjusted promptly, and the scope of adjustment is bigger, and the scope of application is wider.

It will be apparent to those skilled in the art from this disclosure that various other changes and modifications can be made which are within the scope of the utility model as defined in the appended claims.
