Description

  The present invention relates to a linear slide rail and its retainer.

  As precision feed systems have been developed and improved, linear transmission technology and its products are already the most important part of many precision devices. Various linear structure products such as linear slide rails are often used in human life, processing factories and high-tech equipment. Although linear construction technology is developing very quickly, consumers still want to improve the technology further. In addition, since problems during development frequently occur, various new ideas that can effectively improve the linear structure have been positively developed in related technology industries. The linear slide rail mainly includes a guide rail and a slider that is fitted to and slides on the guide rail. The slider has a rolling surface facing the guide rail, a rolling member interposed between the slide rail and the slider (divided into two types, a chain and a non-chain), and an infinite circulation of the rolling member. A possible circulation module, two end caps attached to both ends of the slider, and a retainer for the rolling member to be kept in place are provided.

  When the slider slides on the guide rail, dust and fine dirt from outside tend to enter between the guide rail and the slider, so that the slider cannot slide smoothly between the guide rail. Therefore, some manufacturers add and attach related dustproof members to the retainer. Currently, a known dustproof member installed in a retainer is difficult to mount in addition to being complicated to manufacture.

  It is an object of the present invention to provide a linear slide rail and a retainer for which each retainer can effectively position two circulation sleeves simultaneously by designing the structure.

A slider in which two housing passages penetrating the part are respectively formed, and two circulation modules respectively attached to opposing parts of the slider, which are formed in two adjacent housing passages, In each case, at least a part of the two circulating sleeves projecting out of the slider and the two circulating sleeves are mounted, and the portion exposed from the two circulating sleeves is rotatable between the guide rail and the slider. Two circulation modules with two rolling units sandwiched between them, respectively on opposite sides of the guide rail The two circulation modules are mounted on the slider and are positioned on the guide rails of the two circulation modules, and are held on the sliders and slidably fitted on the guide rails. And two end cap modules that cover a portion of the circulating sleeve that projects out of the slider. The retainer has a base portion, two side flaps that are integrally extended from the base portion and are each formed with a position restricting hole, a position restricting member having a V-shaped cross section, and a position restricting member Two dust seals formed at the two ends of the V-shaped outer edge, in close contact with the surface near the rolling groove of the corresponding guide rail, and installed integrally with the position regulating member by double injection And a pressing member that is fitted to the base of the position restricting member and the slider, respectively, on opposite sides. In the circulation module positioned by the retainer, the two circulation sleeves are respectively positioned in the position restriction holes of the two side flaps of the position restriction member, and the portions exposed from the two circulation sleeves of the two rolling units are the two side flaps. Each of the position restricting holes is rotatably formed.

And two side flaps 412 to be formed. A stripe-shaped attachment groove 4111 is formed along the longitudinal direction of the base portion 411 at a substantially central portion. A set of locking clips 4112 is formed at portions adjacent to the two ends of the mounting groove 4111. The two side flaps 412 are each formed with a longitudinal position restricting hole 4121 along the longitudinal direction. One position restricting hole 4121 of the two position restricting holes 4121 is shifted from one side of the mounting groove 4111 (for example, the upper position restricting hole 4121 is located on the right side of the mounting groove 4111 in FIG. 6). Another position restricting hole 4121 is installed on the other side opposite to the mounting groove 4111 (for example, the position restricting hole 4121 located below is shifted to the left side of the attaching groove 4111 in FIG. 6).

  That is, each position restricting hole 4121 is surrounded by two long side walls 4123 and two arcuate walls 4122, and the two long side walls 4123 extend in directions opposite to each other to form a long position restricting column 4124. It is formed. The distance between the end faces of the two position restricting columns 4124 of each side flap 412 is smaller than the distance to the adjacent arcuate wall 4122 site. Mounting bars 4125 that can be fitted to the side positioning grooves 212 are geometrically provided at positions away from the base 411 in the two side flaps 412. The pressing member 42 includes a fitting column 421 and two engaging columns 422. The fitting column 421 has a substantially hexagonal cross section perpendicular to the longitudinal direction. The opposite side portions of the fitting column 421 (for example, the front side and the rear side of the fitting column 421 in FIG. 5) are geometrically fitted into the positioning groove 211 and the mounting groove 4111, respectively. The two engaging columns 422 are cylinders, and are formed by extending integrally from two opposite end surfaces of the fitting column 421 (for example, the left side surface and the right side surface of the fitting column 421 in FIG. 5). .

  One side of the fitting column 421 of the pressing member 42 is fitted into the mounting groove 4111 of the position regulating member 41. The two engaging columns 422 are respectively sandwiched between two sets of locking clips 4112. The two long dust seals 43 are formed at positions away from the base portion 411 of the two side flaps 412 and are located almost on the opposite side of the mounting bar 4125.
