Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a roller shaft for door and window sliding rails. Background Technology

[0002] As core components of buildings for achieving lighting, ventilation, and space division, the evolution of doors and windows in terms of structure and function has always revolved around convenience and durability. Traditional doors and windows mostly rely on hinges or tracks for opening and closing, but with the increasing demand for large-size, lightweight, and low-friction opening methods in modern architecture, sliding track systems have gradually become the mainstream solution. Door and window sliding tracks support the smooth sliding of door or window sashes through a linear guide structure, and their performance directly depends on the matching precision between the track and the moving parts. As a key actuator of the sliding track system, the roller shaft converts the weight of the door sash into rolling friction through a bearing structure, significantly reducing the opening and closing resistance and wear problems caused by traditional sliding friction.

[0003] During the use of the roller shaft, it was found that at the connection point between the roller shaft and other components, problems such as uneven load distribution leading to misalignment were prone to occur. Furthermore, long-term compression and sliding on the slide rail easily caused severe wear on the roller edges. To address these issues, this invention provides a roller shaft for door and window slide rails. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a roller shaft for door and window sliding rails, which solves the problems found during the use of roller shafts, such as the tendency for the connecting shaft to be misaligned due to uneven load at the connection point between the roller shaft and other components, and the problem that long-term compression and sliding on the sliding rail can easily lead to severe wear on the roller edges.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a roller shaft for a door and window sliding rail, comprising a roller shaft body, the roller shaft body comprising a roller component and a rotating shaft, the roller component being rotatably connected to the sliding rail, the rotating shaft being fixedly connected to both ends of the roller component, and a tapered groove being provided inside the rotating shaft, the tapered groove being used to achieve quick centering and positioning with a matching tapered buckle, and to reduce uneven wear of the roller component caused by installation errors.

[0006] Preferably, the tapered groove is also used to smoothly transition the axial load from the shaft end to the roller component, avoiding stress concentration at the shaft end.

[0007] Preferably, the conical groove and the corresponding conical retaining spring form a mechanical relationship that becomes tighter with increasing pressure, making it less prone to loosening during vibration.

[0008] Preferably, a chamfered groove is provided on the outer side of the rotating shaft, which is used to reduce the wear of the edges and corners of the rotating shaft and the slide rail.

[0009] Preferably, a connecting ring is fixedly connected to the outer end of the tapered groove, and the connecting ring is fixedly connected to both ends of the rotating shaft. The connecting ring is used to connect the tapered buckle.

[0010] Preferably, the outer end of the roller component is provided with a roller chamfer groove, which is used to reduce the wear of the edges and corners of the roller component and the slide rail.

[0011] Preferably, a central groove is provided at the center of the roller component, and the central groove is used to connect the bearing.

[0012] Preferably, the central shaft slide groove has side ring grooves at both ends, and a rubber ring is installed in the side ring groove. The rubber ring is used to reduce the wear of the roller components and the connecting bearing.

[0013] This utility model discloses a roller shaft for a door and window sliding rail, which has the following beneficial effects: the roller shaft of this door and window sliding rail has tapered grooves at both ends of the shaft, so that the roller shaft will not deviate from the connecting clips, resulting in misalignment due to uneven load, and the pressure on the shaft is reduced. The chamfer design reduces the wear between the roller shaft and the sliding rail. Attached Figure Description

A tapered groove 123 is provided inside the rotating shaft 12. The tapered groove 123 is used to achieve quick centering and positioning with a matching tapered buckle. The tapered groove 123 guides the buckle or fixing component to slide into the positioning quickly without the need for precise alignment of the tapered groove 123, and reduces uneven wear of the roller component 11 due to installation errors, thus extending its service life. The tapered groove 123 is also used to smoothly transfer axial load from the shaft end of the rotating shaft 12 to the roller component 11, avoiding stress concentration at the end of the rotating shaft 12 and improving the fatigue resistance of the rotating shaft 12 shaft. It is especially suitable for heavy-duty sliding doors. The tapered groove 123 and the corresponding tapered snap spring form a mechanical relationship of increasing pressure, making it less prone to loosening during vibration, and suitable for high-frequency vibration environments.

A connecting ring 122 is fixedly connected to the outer end of the tapered groove 123. The connecting ring 122 is fixedly connected to both ends of the rotating shaft 12 and is used to connect the tapered buckle.
