Description

Technical Field

[0001] The utility model belongs to the technical field of roller guide rails and relates to a roller guide rail structure. Background Art

[0002] At present, sliding guide rail structures are widely used in various fields. The stability and reliability of their performance directly affect the accuracy of the entire applied device. Therefore, the sliding guide rail structure is required to have high stability and reliability. Most of the existing technologies use roller guide rail structures to ensure their precision and accuracy.

[0003] For example, a utility model patent with application number CN201320558204.8 provides a roller-supported guide rail moving structure, including a guide rail and a bag pushing frame, and also including a transverse roller and a vertical roller connected to the bag pushing frame. The cross-section of the guide rail is a groove type with one side open, the transverse roller abuts against the inner side wall of the guide rail, and the vertical roller abuts against the lower wall of the guide rail.

[0004] To sum up, in some existing technical solutions, the transverse roller and the vertical roller are two separate components, so the horizontal space they occupy is relatively large. At the same time, since the two components are at a certain distance, there is a torque at a certain distance when force is applied, and sufficient accuracy cannot be guaranteed, so there is a lot of room for improvement.
