Description

Technical Field

[0001] The utility model relates to the technical field of linear guides, and in particular to a linear guide mechanism. Background Art

[0002] Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides, and are mainly used to support and guide moving parts for precise reciprocating linear motion. According to different friction properties, linear motion guides can be divided into categories such as sliding friction guides, rolling friction guides, elastic friction guides, and fluid friction guides. Linear guides are also called linear rails, slide rails, linear guides, or linear slide rails, and are suitable for occasions with high-precision or high-speed linear reciprocating motion. They can bear a certain torque under high-load conditions and achieve high-precision linear motion.

[0003] For the guide rail, in the prior art, after retrieval, the utility model patent with the Chinese patent publication number CN205189590U discloses a new type of guide rail. The new type of guide rail includes a guiding end head, a guide rail, and expansion screws. The guiding end head and the guide rail are fixed to the ground by the expansion screws. The new type of guide rail involved in the utility model mainly consists of a guiding end head and a guide rail, and the two can be fixed to the ground by expansion screws. A positioning piece is provided on the guiding end head, and a positioning groove is provided on the guide rail, so that the guiding end head and the guide rail can be quickly assembled together. The use of this new type of guide rail reduces the labor intensity of workers and improves work efficiency. In addition, the structure of this new type of guide rail is reasonably designed, easy to assemble and install, efficient and fast to use, and can make the work site more tidy and orderly, and is suitable for popularization and use.

[0004] Although this patent has the advantages of convenient assembly and installation, efficient and fast use, etc., in the connection process, only relying on the positioning piece and the positioning groove for positioning enables the guiding end head and the guide rail to be quickly assembled. However, this connection method relying only on the positioning piece and the positioning groove is prone to loosening during the movement process, making it difficult to maintain the stability of the movement, and thus difficult to ensure that the moving part performs precise linear motion along the predetermined trajectory.

[0005] Therefore, those skilled in the art have provided a linear guide mechanism to solve the problems raised in the above background art. Summary of the Utility Model
