Description of the Invention: [Technical Field] The present invention provides a bead structure of a linear slide rail, and particularly a novel technique for improving the bead groove of the load side path and the direction revolving portion path connection. The diameter has the advantage of improving the smoothness of the linear slide, maintaining high quality, prolonging the service life and the like. [Prior Art] The techniques for linear sliding bead groove are known at present, and can be classified into the following three categories: 1. Please cooperate with the figure, the linear sliding rail is composed of the sliding roller having the first rolling groove 11 The slider 2 of the second rolling groove 21, the first rolling groove 11 and the first rolling line 41 form a load side path 23 for rolling the rolling element 3, and the cover 2 and the end cover 25 are mounted on both sides of the slider 2. The cover plate 26 and the end cover 25 have a directional turning path 24 for providing the rolling element 3 in an infinite loop, and the directional turning path 24 must have a larger aperture than the load side path 23 to facilitate the rolling element 3 not to be received in the directional turning path 24. The pressing 'causes the portion of the load side path 23 that is connected to the direction turning path 24 to cause a gap A, so that when the linear sliding operation is performed, the rolling element 3 hits the second rolling groove of the slider 2 through the gap A. 21 generates vibration, which not only has stress concentration, but also makes the second rolling groove 21 of the slider 2 easy to be damaged and makes the linear sliding rail run less smoothly. 2, smart read the picture - it is the representative of the US patent US6807746, 200829806

Because the slider 2 is large, it will greatly increase the manufacturing time and cost, and - shown, the basin cover 26 is not directly fixed to the slider 2, but the end cover 25 is fixed to the slider 2' so that the slider 2$ is rolled (four) and does not meet the requirements of precise positioning. Assembly break A may result. A 3, as shown in Chinese Patent No. I259876, M264395, which has a fitting groove formed at both ends of the second rolling groove 21 of the slider 2, and the corresponding cover on the cover plate has a protruding portion that is inserted into the assembly concave surface. According to the direction of the fine-grained direction, the path 24 and the load-side path 23 are rotated. However, as shown in FIG. 1, it is limited that the aperture of the direction-turning path 24 must be larger than the activity margin requirement of the load-side path 23, so both ends of the load-side path 23 The portion connected to the direction turning path 24 still produces a gap A, so there is still a disadvantage of FIG. It is known from the above that the bead groove formed by the linear slide rail connecting the direction slewing path % and the load side path 23 has a gap A formed by a predetermined aperture size difference, or a poor assembly position. The fault A can cause the / swaying element 3 to pass through the fault a, which will have an adverse effect and greatly detract from the quality of the linear slide. This is the current processing technology cannot break through 6 200829806.
