Description

Technical Field

[0001] The utility model relates to the technical field of linear guide rails, in particular to a linear guide rail with a limiting structure. Background Art

[0002] Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving parts to perform reciprocating linear motion in a given direction. Depending on the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types. Linear guides are also called line rails, slides, linear guides, and linear slides. They are used in linear reciprocating motion occasions. They have a higher rated load than linear bearings and can bear a certain torque. They can achieve high-precision linear motion under high load conditions. They are divided into square ball linear guides, dual-axis core roller linear guides, and single-axis core linear guides.

[0003] In the prior art, when a linear guide rail is in use, a limiting block is installed at the end of the guide rail to limit the slider and prevent the slider from falling off the guide rail. The limiting block lacks a buffer structure, and the slider directly contacts the limiting block, which can easily cause damage to the slider. In addition, the guide rail needs to maintain stability after installation. If the stability is insufficient, the guide rail is prone to offset and shaking during use. Utility Model Content
