Easy-to-assemble skid wheel set

Abstract

The invention discloses a slide rail wheel set convenient to assemble. The slide rail wheel set comprises an idler wheel frame on which idler wheels are mounted; the idler wheel frame is sleeved with a shell; a horizontal bolt and a traction screw are respectively used for horizontally and longitudinally connecting the idler wheel frame with the shell; front and rear edges, opened downwards, of the shell are each provided with a plurality of embosses; front and rear surfaces of the idler wheel frame are each provided with a plurality of vertical grooves matched with the embosses in amount; each vertical groove penetrates through the upper and lower ends of the idler wheel frame; the space between opposite positions of every two vertical grooves is the same as that between the opposite positions of every two embosses, but the embosses and the vertical grooves are arranged in a staggered manner. During assembly, the idler wheel frame is sleeved with the shell from bottom to top along the position of each emboss and opposite to each vertical groove; the idler wheel frame can be limited by the embosses by being displaced a bit until the embosses and the vertical grooves are staggered, and the idler wheel frame cannot fall off or leave from the shell; at the moment, the assembly can be finished after slowly finding positions and mounting the traction screw and the horizontal bolt in place. The slide rail wheel set disclosed by the invention is ingenious in conception, convenient to assemble and capable of being widely applied to assembly of sliding doors and windows.

Description

technical field [0001] The invention relates to a slide rail wheel set for sliding doors and windows. Background technique [0002] Sliding doors and windows generally all need to be equipped with a slide rail wheel set on the lower frame of the door leaf or window sash, so that the door leaf or window sash can stand upright on the slide rail and slide along the slide rail. As for the structure of the slide rail wheel group, the slide rail wheel group includes a shell formed by sheet metal stamping, which is a rectangular box with an opening downward as a whole, and the first connecting hole is opened at the right end of the shell; the shape of a roller frame is also It is a rectangular box with an opening downward, and the second connection hole opened at the right end of the roller frame. Several rollers are installed on the roller frame through the roller shaft; the roller frame is inserted into the shell and the roller part is exposed; multiple The horizontal bolt conne...

AI Technical Summary

Problems solved by technology

However, it has been found in practice that often due to the deviation of the stamping size, the second connection hole cannot be aligned with the first connection hole, which makes it difficult for the traction screw to pass through the two holes in one go, resulting in failure of assembly

Therefore, workers are accustomed to replace the installation sequence, install the traction screws first, and install the cross bolts horizontally, because even if the two connection holes at the ends are occasionally misaligned, they are connected first, so that the bolt holes of the cross bolts themselves are not aligned. It will also be smaller, which can be completely ignored, and can be tightened with force, and the bolt hole size of the general horizontal bolt is large, easy to adjust

However, since the end part is installed first, it is often that after the roller frame is inserted into the shell, the hole position is not aligned, and the roller frame will fall down by itself due to gravity, causing workers to assemble parts. inconvenient
