Problems solved by technology
But the upper part of this roller skating still has its weakness, that is, the center distance between the two pulleys installed in parallel is fixed, that is, the distance between the outer wheel surfaces of the two pulleys is also fixed, and the matching The distance between the aluminum alloy upper rail grooves cannot be changed
Therefore, the use of this roller skating seems to have certain limitations. It can only be assembled with an aluminum alloy groove of one specification, and a groove that is too wide or too narrow cannot be used.

A quick positioning structure for sliding-door buffer guide pulleys comprises a main fixing board and a quick positioning device arranged on the main fixing board. The quick positioning device comprises a sliding plate hinged with the main fixing board, the left guide pulley arranged on the left side of the sliding plate and a right guide pulley arranged on the right side of the sliding plate, adjusting plates are further arranged on the sliding plate in a riveted manner, the adjusting plates include a base plate and a connecting plate, a sliding groove is arranged in the connecting plate, anda retaining rivet penetrating the sliding groove to be riveted with the sliding plate. The quick positioning structure has the advantages that at least two locking grooves are arranged in the adjusting plate, so that when an eccentric screw is positioned, the adjusting plate is locked by using retaining screws penetrating the locking groove to be connected with the main fixing board to have the guide pulleys fixed.
Description
technical field [0001] The invention relates to a hardware accessory for a sliding door, in particular to a quick position adjustment structure for a guide wheel of a buffer for a sliding door. Background technique [0002] In the existing buildings, the left and right translational sliding doors are favored by the majority of owners because of their large opening and closing area. Generally, pulleys are installed at the lower end of the sliding door and pulleys are installed at both sides of the upper end of the sliding door, which are hardware accessories commonly used in architectural decoration. The lower pulley at the lower end of the sliding door has the functions of bearing, pushing and pulling, and rolling, and the upper pulley at the upper part has the function of guiding. But pulley commonly used at present, it is simple in structure, only is made up of two pulleys, pulley shaft and fixed plate, and fixed plate is installed on the side upper end of door horizontal...
